Chapter 1: Chen Lun's Classroom (Part 1)

The morning sun shone brightly on the tree-lined path, leading to Yingzheng Academy. Students,
dressed neatly, entered the school, creating a vibrant scene.

At this moment, a soft murmur arose among the students, some whispering, others peeking furtively. A beautiful woman gracefully
walked through the crowd, her long, soft hair flowing in the wind. Her elegant figure, accentuated by her suit, exuded mature charm. This was none other than Matsushita Keiko, the new English teacher at Yingzheng Academy
. Keiko immediately became an idol among the students upon her arrival. This is an all-boys
school, and the 24-year-old Keiko, with her rational beauty, quickly earned the nickname "Eishi Beauty."

From a young age, she had aspired to be a teacher, and having just obtained her teaching qualification three months prior, Keiko couldn't wait
to start teaching at the prestigious Eishi Academy.

A month passed after she took up her post… (Oh… it's Koda…) On her way home, Keiko encountered
a boy wearing the Eishi Academy uniform—Harukawa Koda. He was a student in Class 3-3 of the third year at Eishi, and Keiko had been Koda's tutor during her
university years when he was in junior high

… "Koda."

Harukawa Koda turned around, saw Keiko walking towards him, and showed a surprised expression.

"I… I have something to do…" He turned away and hurriedly ran off.

Watching the model student Harukawa's retreating figure, Keiko felt uneasy.

Not long after, Kayo, the mother of Harukawa Koda, came to visit Keiko.

"Long time no see... I was planning to visit you..." Keiko offered tea.

"Not at all, my son is going to be under your discipline again..." Kayo accepted the tea.

"What brings you here?"

"It's because..." Kayo hesitated, lowering her head. "Because I wanted to talk about Koda... he... he's
become a delinquent." Kayo's hand holding the teacup trembled slightly.

"What?" Keiko still couldn't believe what she was hearing. The once innocent student had become a delinquent?

"Yes, he doesn't like school, he comes home very late... lately he won't talk to me... his father passed away after he entered junior high school
, probably because I spoiled him too much." Kayo gently wiped away the small tears that rolled down her cheeks.

"I only teach Koda two classes a week, and he has the best grades, so he can't be a bad student... Besides, he's already
a senior in high school... It's the age when he doesn't like to be disturbed. I just came to the school, so I don't know the situation in the class yet,
but I'll talk to the tutor about it. Don't worry!" Keiko reassured Kayo.

"I'm sorry, Mr. Matsushita only recently arrived and he's already causing you trouble, but considering I taught Koda before... please
help me..."

"Don't mention it, it's my duty as a teacher."

After Kayo left, Keiko also worried about Koda's situation: "Speaking of which, Koda's been acting
strangely . Could it be...? The principal said there was a disturbance at the school last year, could it be related to Koda's change?"

"A disturbance last year? Oh, it's just that our famous school, like other schools, had a delinquent student.

It was Kuroda from Class 3-5. He entered as a substitute... but his grades couldn't keep up, so he went bad
. He gathered other students with poor grades and formed the 'Kuroshikai,' using violence both inside and outside the school.
Since our school didn't have any delinquent students before, the principal and teachers didn't know how to deal with it..." Keiko
went back to school early that morning to inquire about what had happened.

The colleague took a deep drag on his cigarette and continued, “The result was a split between a hardline faction that expelled delinquent students and a more compassionate faction that supported
remedial education… The hardline faction was represented by your predecessor, Ms. Yoshizawa, while the compassionate faction was represented by
Mr. Yokota, who taught math. When classes were being reorganized, the delinquent students were grouped into Mr. Yokota’s third-year, fifth-class. Ms. Yoshizawa was unhappy and resigned; you’re here
to replace her… But don’t worry, Mr. Yokota is probably quite effective at guiding them; the recent ‘Kuroshi-kai’ (a group of students who frequent the Kuroshi-kai)
hasn’t been doing much .”

“Now it seems they also do extra tutoring after class or hold study sessions at Mr. Yokota’s house, so Mr. Yokota
’s influence has increased, and he’s gained the principal’s appreciation…”

“But why would a good student like Harukawa be placed in fifth-class alone?” Keiko pressed for
details about Harukawa.

“…This…this is because…at least one good student needs to be a role model for the others,”
the colleague stammered.

Keiko pondered the matter repeatedly, but couldn't find any problem. She just felt things weren't so simple.

As soon as class ended, Keiko discussed Harukawa's situation with his homeroom teacher, Yokota.

"I have my own educational principles, please don't meddle!" Yokota replied, displeased.

"One is influenced by one's company. Harukawa was a very good student in middle school. Why does Mr. Matsushita only care about Harukawa…"

Before Keiko could finish, Yokota interrupted her.

"You two had a special relationship when you were Harukawa's tutor, didn't you? Harukawa Koda is a handsome
young man , and... Harukawa seems to really like Matsushita-sensei. Of course, you're also
the new, beautiful teacher whom all the students admire and praise..."

Hearing Yokota's lewd words, Keiko trembled, unable to believe such words could come
from

... "I'm talking about serious matters. Yokota-sensei, do you think Harukawa can sacrifice himself for other students?" Keiko rarely
got angry .

"Why does Matsushita-sensei think that? Did Harukawa say it?"

"No, it was her mother..." "

Oh, that beautiful widow?... She seems unwilling to let her child be independent... Don't get involved in this, or
I won't be responsible for any regrets later..." Yokota seemed to be making a threat.

After school, in the principal's office, Keiko summoned Harukawa for a detailed discussion.

"I asked the principal for permission to use this place. No one will come. Your mother is very worried about you.
What's troubling you?" Keiko asked softly.

"I don't know what my mother said, but I'm not a child anymore. Please don't interfere in my affairs..." Harukawa
replied sullenly.

"What? What did you say? Making your mother worry, don't you feel bad?" Keiko scolded angrily.

"Talking about your troubles will make you feel better..." Keiko said, suppressing her anger, and took Harukawa's hand encouragingly.

"Being with Kuroda all the time, it's not your wish... You're definitely being forced..."

"No, no!..." Harukawa suddenly became agitated after Keiko mentioned Kuroda's name. "Teacher,
don't meddle... You'll regret it!" Harukawa exclaimed and stormed out.

Keiko knew then that the situation was quite serious.

Finally, the day arrived for Class 3-5. After class, a few students stayed behind as cleaning duty,
including Kuroda from the "Kuroshikai."

"You two seem to be very close to Harukawa... What do you usually do together after class?" Keiko
probed Kuroda.

"We don't play around, we study hard. We have university entrance exams in a year... We automatically
study " Kuroda replied respectfully.

"Automatic? What good will that do for Harukawa?"

"Not necessarily. There are some things we know more about than he does, and... Yokota-sensei is happy to say that this
has improved teaching!" Kuroda said confidently.

"Oh, I'd also like to see your extracurricular activities."

"Really? With Matsushita-sensei here, everyone will be more energetic," Kuroda said happily.

"Then please come to this classroom after class tomorrow. Goodbye, Matsushita-sensei."

Before they knew it, it was around five o'clock the next day. All the students had left the school, and the once noisy
corridors were now quiet, save for the sound of Keiko's high heels.

"Oh, it's Mr. Matsushita. I heard he's going to check on the students' after-school study sessions. How kind of him!"

The cleaning lady outside the classroom greeted Keiko, but her eyes were secretly glancing at Keiko's shapely buttocks, something Keiko
was unaware of.

"Click..." Keiko pushed open the classroom door and saw only five students huddled together, seemingly
discussing something, but it didn't seem to be about homework. Seeing Keiko open the door, the five students' expressions became
strange.

"Only five people here? Where's Harukawa?" Keiko walked over to them, feeling that the situation
was somewhat different from what she had imagined.

"Click...bang..." The sound of the door opening rang out, and Keiko turned around to see that Kuroda had somehow walked
behind her and closed the door.

"Today is the first time our beloved Matsushita-sensei is attending, and the four of us from the 'Kuroshi-kai' have decided
to take a commemorative photo with him, followed by a welcome party..." Kuroda said casually,
his

hands behind his back. At that moment, the other four stood up, their eyes filled with sinister intent. Keiko felt a strong sense of oppression and involuntarily retreated until her back hit the blackboard.

"...A welcome party or a commemorative photo is too much...and besides, I didn't say I wouldn't
come again..."

Kuroda: "It can't just be once, so we absolutely have to take a nude photo of the teacher!"

"What did you say?!" Keiko knew they had ill intentions, but she hadn't expected them to say such things
. After all, this was on campus; surely they wouldn't be so outrageous.

"Help...!" Keiko remembered the school janitors cleaning outside the door and tried to shout for help. But
the members of the Black Society acted extremely quickly. While two men restrained Keiko's upper body from behind, one of them stuffed a pre-
prepared hand slap into Keiko's mouth and tied it behind her head, silencing her.

"Ah...ah..." Keiko tried to call out, but could only make low, muffled sounds.

The man behind her gently tried to remove Keiko's suit jacket, and Keiko could only struggle to
resist .

"Don't move around too much, or you'll tear your clothes. Do you want to go back in torn clothes?" Keiko, whose upper body was restrained,
was no match for the men's strength, and her jacket was easily removed. Just as all her attention was focused on
her upper body a chill on her lower body. She saw that another man behind her had taken off his suit skirt and pulled it to the ground, revealing
pure white underwear.

"Oh, your panties are snow-white, what an innocent teacher," Kuroda said flirtatiously from the front.

"Ugh!" Keiko felt a sharp pain in her shoulders. The man who had removed her top forcefully
bound her hands behind her back with rope, the thick hemp rope digging into her flesh and chafing her wrists.

The situation in the classroom changed drastically, something Keiko had never imagined.

"Huff...whoosh...whoosh..." A soft murmur rippled through the cramped room, but Keiko kept her eyes tightly shut, thinking, "If
this is a dream, please wake up quickly." Her bra was removed, her legs were spread wide, and she was tied
to the table at the knees with rope. Her full breasts trembled with her body, and her slender waist resembled the belly of a queen bee,
without a trace of fat. She was left only with white panties to cover her most shameful lower body, but
it was only a matter of time before that defense was removed.

"Wow, I never imagined a naked body under a suit could be so beautiful..."

"Yeah, it's a waste for her to be a teacher; she should be a nude model."

"Such big breasts! She hasn't even given birth yet and already has such enormous breasts; her only purpose must be to seduce men."

"Behind that innocent face lies a devilish figure..."

Exposing her body in front of her students, and receiving their judgments and lewd comments, a chill ran through Keiko.

"Truly a beautiful and virtuous woman, completely different from a cricket..." Kuroda approached Keiko and breathed into her ear
.

"Cricket is your ex-teacher, Yoshizawa-sensei... Matsushita-sensei inquired about us and told you why Cricket
resigned ... Cricket wanted to expel us, so we gang-raped her... At first she didn't want to,
but in the end she was twisting her waist and moaning, and then we called her over to play with her a few more times... That's why she resigned. We weren't
interested in that old woman; she can't compare to a teacher..."

Keiko finally understood what the commotion at school had been all about.

At this moment, Ihara, wearing glasses, knelt down, staring intently at the barely visible black part inside her thin underwear, and
hooked a small section of the edge with his finger: "Is this a black forest like Cricket's?"

Seeing Ihara's actions, Keiko knew this was the moment they wanted to take off their underwear. "Ugh...ugh..."

Unable to utter a sound, her anxious heart caused her hips to sway slightly, and the urge to urinate intensified, but
this only fueled the boys' lust.

"Ugh..." Kuroda flicked Keiko's nipple, causing her to let out a deep breath.

"They dream of the teacher's naked body every night and even have nocturnal emissions. This makes it difficult for them to concentrate on their studies."
"Well , let's show them the real thing. It's a teacher's responsibility to make the students happy." Kuroda
took out a pair of scissors from the wooden box on the teacher's desk and placed them along the side of her underwear.

"Ugh...ugh..." Keiko shook her head, indicating no. Her nervousness caused her urine to rush
to her labia; if she relaxed her muscles, she would probably urinate.

"I'll cut up the beautiful teacher's vulva for you. Don't move around, or you might hurt everyone's beloved
teacher ."

"Cut! Cut!" "...With two crisp snips of scissors, a white sheet fell from Keiko's body.
Her genitals were completely exposed to the students. Overwhelmed with shame, Keiko lost her composure, her mind went blank,
and the will that had been controlling her genitals crumbled. A gush of hot urine spurted out, splashing onto the ground.

"Her vulva is even more beautiful than in my dreams! I never imagined Keiko-sensei would give us a urination performance."

"Her vulva shines with urine; it must be the same when it's covered in vaginal fluid."

Kuroda: "Don't just stare. Quickly get the camera so I can take a picture with the teacher." "

Yes, Chairman." Kuroda

walked behind Keiko, his right arm around her slender waist, his left hand on her heavy, beautiful
breasts, rubbing her nipples with two fingers. Ihara and the other boys also held cameras, focusing from different angles
.

The light reflected from the lenses chilled Keiko, and she turned her head away.

"Face your pretty face towards the camera." Kuroda used his hand, which had been on Keiko's waist, to turn her face towards
the camera, and Keiko was thus photographed in a humiliating manner.

Afterwards, her beautiful vulva was photographed in numerous close-ups, and each person
posed . The sound of shutters and flashes in the room was like a relentless barrage of thunder and lightning assaulting Keiko's body. But... this
was only the beginning of a nightmare.

**********************************************************************

Kuroda: "If you promise not to scream, take the gag off your mouth..."

Keiko thought this would be her only chance to talk, and perhaps she could persuade them, so she nodded in agreement.

"Quickly untie the ropes; if someone sees you, you'll be prosecuted by the police." " I met Mr. Tajima, the school janitor, before I arrived...
" Keiko, her gag just removed, launched into a series of statements about the consequences, hoping to
scare them off.

"Don't worry, no one will come to the third floor now. We had him keep watch, but he's been
peeking in ... Come in, you've been watching for a while now."

"Click... clack..." The door opened again.

"Don't worry, Mr. Matsushita, no one will come..." The janitor, Tajima, entered.

Keiko: "Ah! Don't look! Close the door!"

"Don't shout. There's no one on the third floor, but there are still many people on campus. You don't want to
appear like this in front of everyone, do you?" Kuroda covered Keiko's mouth with his hand.

"Please, please let me go! What have I done to deserve this...?" Tears
welled in Keiko's eyes , and her voice became hoarse.

"There are many reasons. First, to shut up that nosy Matsushita-sensei. Second, since you're
curious , I'll let you know our secret, but you also need to have your own secrets..."

Keiko's breasts, waist, and thighs were being caressed by the four boys.

"Your skin is so smooth."

"Just thinking about making love with you in the classroom makes my blood boil. I'm so excited."

"I can't resist anymore, President, let me insert it here." The obese Nagano asked Kuroda for permission,
his fingers already probing towards Keiko's vulva.

"No! Don't touch here!" "When Keiko heard they were about to gang rape her, she couldn't help but scream.

Ihara, standing beside her, covered Keiko's mouth again, saying, 'Teacher, are you screaming so loudly because you want the other
teachers and students still at school to see your naked body? How about I go outside and shout, "Let everyone who wants to see our beautiful teacher come to
Class 3-5!"'

Keiko shook her head, clearly aware of her situation. 'Okay, I won't scream anymore, and
I promise I won't tell anyone about today's events. Let me go...' Keiko stated her terms.

'Teacher, you don't understand your position. Speak more respectfully. We can gang rape you right now
.' Kuroda said, placing his hand on Keiko's vulva and rubbing it.

Seeing Kuroda's actions, the others also began to grope Keiko.

'Wow! Teacher's thighs are so bouncy!'" "

Teacher's peaches are such a beautiful color, just like a virgin's."

...

Everyone also praised Keiko's body.

"Oh, right, there's a third reason: differential treatment. Harukawa is a handsome boy, but the teacher only gives him
sex education outside of class. It's so unfair." Kuroda quickened the rubbing motion of his hand on Keiko's vulva.

"Nonsense! Harukawa and I have nothing to do with each other..." Keiko denied, her whole body stimulated.

"No need to hide it anymore. It started when you were a tutor, didn't it... But why make love in the principal's office?"

The school worker, Tajima, stepped forward and scanned Keiko's entire body with lewd eyes.

"She's even more beautiful up close. Her breasts are so high and full, her waist and thighs are so beautiful..." "

No!" "I didn't, you're lying," Keiko retorted.

"I saw everything that happened between the teacher and Harukawa in the principal's office. The teacher forced herself on Harukawa, but he refused
and ran away," Tajima continued his lies.

"It's a misunderstanding, it's not what you think..."

"Stop arguing. Let's call Harukawa over and ask him. Also, let the students who haven't left school yet come up to testify,
and they can see the beautiful teacher's naked body," Kuroda ordered.

"Okay, and collect some admission fees too," Ihara said, making a move to leave.

"Don't go! I admit it, don't embarrass me anymore."

Keiko hoped this would satisfy them and reduce her torment, but Kuroda wasn't about to
let .

"Admit it?" "It wasn't just last time, you've been secretly making love for a long time!"

"You wicked teacher, when did you take Harukawa's virginity...?" Kuroda kept verbally
humiliating .

“No… I haven’t been with a man…” Keiko whispered, but it didn’t escape Kuroda’s ears.

“Oh? Really? A twenty-four-year-old beauty can be a virgin?” Kuroda deliberately raised his voice, causing
a stir.

“Really?”

“It’s unbelievable.”

“But judging from this beautiful color, perhaps it’s true…” Ihara and Tajima carefully observed Keiko’s
vulva and parted her labia.

“Crickets have mates, so there’s no problem, but a virgin is a different story…” Kuroda pondered.

“The more proud a beautiful woman is, the less she wants anyone to know about her shame, let alone being gang-raped by us…”

Keiko grew increasingly horrified as she listened: “No… this can’t be… I will never tell anyone about what happened today,
so …”

“Losing a virgin in the sacred classroom isn’t good either… If you agree to our terms, I can reconsider.”

Kuroda seemed to be conceding, but he already had other plans in mind. His first step was to completely
erase Keiko’s sense of shame. Keiko thought she was saved and repeatedly agreed.

“President, no, how do we deal with that hard penis?” The others also thought Kuroda was giving in.

“It’s like a dog in heat. If you can’t resist, just watch your idol teacher masturbate. Let’s have a competition to see who can shoot the most accurately.”

Kuroda drew a line on the ground in front of Keiko’s feet with chalk. He whispered in Keiko's ear, "How about it? Let them
masturbate in front of you, okay? That's one of the conditions. It's better than gang rape, right?"

Keiko knew she really had no choice (yes, it's better than being gang raped), but hoping the Kuroda
Association would keep its promise, she nodded in agreement.

"Teacher, I'll go first." The first to step forward was Ihara, who reached out and unzipped his school trousers,
revealing his already eager, hot penis, and quickly began to stroke it vigorously with his hand. The foreskin stretched and contracted,
intermittently . Apart from textbooks, Keiko had never seen a real penis before. Now, before her eyes
, her student was performing lewd acts on her, the secretions seeping from the glans making
a rhythmic sound as the foreskin rubbed against her.

Shame made Keiko turn her face away and close her eyes, her heart screaming... This can't be, this is too much...
The shy face of Keiko in front of him, coupled with her beautiful body, brought Ihara's masturbation to its peak.

"Ah... This isn't a dream, this is a real beautiful teacher... My masturbation object... Teacher...
I can't... take it... anymore..." With rapid breathing and words, Ihara immediately ejaculated two
thick streams of semen onto Keiko's body.

(...Heh... Matsushita Keiko, this is just the beginning, I'll make you suffer even more later...) Kuroda
chuckled inwardly.

(II)

The arrival of night made the daytime Eisei Academy deathly silent, with only a few dim streetlights outside the school walls, and
the chirping of summer insects in the school's woods was the only sign of life. Yingzheng Academy, usually deserted except for school workers and security guards,
was unusually lively tonight. The classroom of Class 5, Grade 3, was lit, but it exuded a sinister aura, completely
out of place with the school's atmosphere.

The classroom, which should have been pure, now reeked of a foul stench, but what was most unexpected was that the source of the stench
was a stunningly beautiful woman. High, full breasts, a fair and shapely bottom, a slender waist and beautiful legs, coupled with a
pretty face full of intellectual beauty—the newly appointed English teacher, Matsushita Keiko, had just become the object of her students' masturbation. From her breasts
down, her body was covered in the semen ejaculated by the boys standing just outside the three-foot line—this was the source of the
stench .

Keiko, experiencing this "baptism" of semen for the first time, was enduring the shameful smell emanating from her body. "Cleaning is my job, Ms. Matsushita. Let me clean you up," said Tajima, the school worker, holding
a floor-cleaning cloth, which he dampened with water and used to wipe the semen off Keiko's body. Since this
would also remove the unpleasant odor from Keiko's body, she acquiesced to the school janitor's service; of course, resistance
was futile.

"No wonder they're so energetic with such a beautiful body; even standing three feet away, they could ejaculate
so much onto your vulva." Tajima wiped the vulva, which was covered in the most semen, with a cloth.

"No...don't wipe that place...ah..."

"Don't be angry, this is the dirtiest part; it needs to be washed properly. But they really have
a lot!"

"Ah...no, don't use that force..." Tajima vigorously rubbed Keiko's vulva with the cloth,
the rough cloth rubbing against her delicate labia. Although Keiko had tried masturbating before, she only needed to
gently tease her sensitive clitoris to achieve satisfying pleasure. But now, under the vigorous
movements , no woman could withstand it, especially under the watchful eyes of everyone, which added a
humiliating pleasure of being tortured. Keiko's vaginal fluids broke free of her willpower and flowed out of her vagina. Keiko tried to
suppress it , not wanting anyone to know about this shameful situation, but she couldn't stop the flow of

her vaginal fluids. "Huh? I wiped it clean, so why is there more and more? I think it's not what they ejaculated on you
, but what the teacher released."

"Don't... say such dirty words, let me go!" Stimulated by the physical and verbal shame, Keiko
twisted her body slightly. "

Matsushita-sensei seems to have a masochistic streak, being played with by students and having the school janitor clean up after her can actually produce
pleasure ..." Just as Tajima was about to bury his head to suck Keiko's nectar, a strong and powerful hand pressed down on his shoulder.

“You’ve received your pay for guarding the place. Go back to your watch. It’s our turn here.” Tajima
, though unwilling, had to do as Kuroda said, his eyes lingering on Keiko’s body as he left.

The members of the “Kuroshikai,” who had been standing by, were now aroused after masturbating and ejaculating. The four of them swarmed around the
naked Keiko. Imai and Morisawa each grabbed one breast, their tongues licking and
sucking things they’d learned from pornographic videos.

Nagano, below, ran his tongue over Keiko’s thighs, then used his thumb and forefinger to part her shy labia
, preparing to lick the pearl within.

“Ah, don’t touch there!” Keiko was terrified at the sight of this place, which had never been touched before.

“Ah!” A sharp pain shot through her head as Ihara pulled her head back from behind.

“Ugh… ugh…” Ihara lowered his head and stuffed his tongue into Keiko’s mouth, making it difficult for her to breathe.

The most sensitive spots on her body were simultaneously being skillfully manipulated by her student,
amplifying the pleasure she had experienced from Tajima earlier. The pleasure signals from various parts of her body surged into her brain, which
had never received so much pleasure before. This caused Keiko's body to react in an unprecedented way, her hot
vaginal fluids spraying onto Nagano's face as he manipulated her vulva.

"Huh? This...this is...?" Even Nagano, who had some sexual experience, was unaware of this woman's
display of pleasure, while the onlookers were even more astonished.

"Is it urine?" Imai asked.

Nagano: "It doesn't taste like that."

Kuroda, who had been observing from the sidelines and wasn't in a hurry to tease Keiko, mocked: "Idiot, this is
what's called vaginal fluid. It's what a woman ejaculates when she reaches her climax, but only the most promiscuous or sensitive women can
do it. Now you know why Ms. Matsushita came to an all-boys school, because no one would do
this ."

"No, because I heard everyone here is a good student. If I had known there were delinquents like you here, I would
n't have come."

"Don't deny it, Ms. Nagano. What's the reason you're so excited about being teased by delinquents?"

Nagano, whose vulva was sprayed with vaginal fluid, stuck out his tongue and deeply licked Keiko's vulva.

"Ah…!" Keiko, who had just denied it, let out a vibrating cry of pleasure under Nagano's tongue, making
her begin to doubt whether she was as Kuroda had said.

(III)

It was 7 PM, three hours after Keiko's nightmare began… The concepts

deeply ingrained in people's minds—that schools are sacred, students are pure, teachers are respected—
were contradicted at Ei-jung Academy today.

“Ugh… ugh…” Keiko's tightly closed eyes and trembling breathing revealed her intense tension
. Her hands were bound behind her back, her face and shoulders pressed against the teacher's desk, her knees kneeling on the desk with her buttocks
raised , her most shameful parts—her vulva and anus—completely exposed to the air. She was drenched in sweat, making the desk wet
.

“It's even more beautiful up close.”

“More beautiful than in my dream.”

Although Keiko didn't turn around, her senses told her that the students were carefully observing her most
private parts.

(Oh...are they still watching? It's a dream, I'm having a nightmare. This couldn't possibly be happening.
Just hours ago I was respected by my students, teaching with unwavering resolve
...and now I'm being toyed with by delinquent students, succumbing to pornography, standing naked on the podium, exposing my front and back to them...)

Humiliated in various ways, though still retaining her virginity, she felt a great deal of shame
. Images from her classes kept replaying in her mind.

"Just looking at her makes you wet. Your face is elegant, but Ms. Matsushita isn't just a masochist, she's an exhibitionist
too ."

"Of course, she came to an all-boys school specifically to expose herself."

"Serving an exhibitionist teacher, spread her buttocks." Nagano used his hands to pull Keiko's thighs apart,
making her already exposed anus even more obvious.

"Wow! Don't look at my shameful place..."

Kuroda: "To be honest, I'm more interested in the back hole than the front."

"No, don't touch there." Keiko felt uneasy as Kuroda approached and made a move.

Kuroda took a small capsule from his pocket, cut it open with scissors, and inserted the pointed end into Keiko's
anus.

"Ouch! What are you doing?" Keiko cried out in pain from her anus.

"It's an enema. One probably isn't enough, so I'll give you three."

Kuroda pressed the capsule hard, and the white liquid inside shot into the intestines. He then injected the remaining two into
Keiko's body.

"No! You can't do this to a teacher. You...you're not human, you're beasts!"

Keiko knew the purpose of the enema and jumped up immediately, knowing that pleading with these beasts was useless
. Keiko immediately launched into a tirade of curses.

"Oh, so you can still say things like that after an enema. No wonder you're a beautiful teacher. But will you still be so dignified when you defecate in front of us later
?" Kuroda chuckled.

Upon hearing their intentions, Keiko felt a chill in her heart and lowered her head to sob, "Why...why do you have to
do this..."

"Is it because we like to destroy or defile beautiful things that my grades have suffered and I've become a bad student
? Is it the responsibility of the current education system or you teachers? Making us spend so much money and then forcing me to repeat a grade—
what does this mean?"

"That has nothing to do with me." "

How can you say that, Mr. Matsushita? As a teacher, you should bear some responsibility, especially since you're
an exhibitionist masquerading as a hypocrite? So we have to punish you. From now on, you're our pet."

"Don't talk nonsense! I'm your teacher! How can students treat their teachers like pets...please...please
...put me down for a moment..."

The contents of her intestines churned, and Keiko could only try to clench her anus tightly.

"What? You need to poop? It's still a long way from when you can't take it anymore!" Kuroda knew Keiko's body
was undergoing an enema and deliberately made things difficult.

"Don't say that... I can tie you up again later, go to the toilet first..."

"Want to go to the toilet? Okay, then swear to be our pet first." Kuroda easily sat back down
in his usual classroom seat.

"If you don't want to be a pet, then I'll make you keep twisting your butt like this until you poop."

"Hmph, if you poop in the sacred classroom, you'll have to lick it clean." Nagano and Ihara
whispered lewd words in Keiko's ear and ran their hands over her body, making it even harder for Keiko to bear.

As her anus was struck repeatedly by the contents of her intestines, Keiko realized she couldn't endure it any longer.

“Ugh…ugh…I can’t take it anymore, I swear, I’ll do anything…please…please let go of the rope…”

“What kind of attitude is that?” Kuroda continued his indifferent attitude.

“The teacher should say it like this…” Ihara whispered something close to Keiko’s ear.

“I…I…” Although she had received Ihara’s guidance, she still couldn’t easily utter the shameful words.

Keiko took a deep breath: "I, Matsushita Keiko, treated Harukawa like
a pet when I was his tutor... and... I'm a masochist who loves being played with or humiliated by my students... Please spare
me... I need to go to the toilet..." Keiko couldn't help but plead midway through her oath.

"You haven't finished your oath yet? Forgot? If you don't continue, you'll have to start over."

Keiko had no choice but to continue: "Yes... I will no longer be a hypocrite. From today onwards, I will be my students'
pet. I swear... Please feel free to play with this shameless, lewd female teacher. If I break my oath... I
will accept any punishment without question... Ah! I can't take it anymore, please..."

"Alright, I'll have you sign the oath in a moment." Kuroda stood up and approached with satisfaction.

"I'll sign, please let me use the toilet quickly..."

"The toilet is too far, you'll be unable to hold it in and will urinate in the corridor. Therefore, I've prepared a portable toilet for you,
just relieve yourself here. Nagano..."

"Yes!" Nagano obeyed and placed an iron bucket in front of Keiko.

Keiko realized their intention. "No, I don't want to!" "

Didn't you say you couldn't hold it in for a while, teacher? Why don't you want to now? Come on, let me help you." The tall
Imai lifted Keiko's legs from behind, like helping a child urinate.

"No, I don't want this..." Although she refused verbally, as her legs were pulled apart, the muscles of her anus, which were tightly closed by
willpower , were also slightly pulled open, and the filth inside her intestines was beyond her control.

"Oh, it's coming out." Ihara raised his camera and focused on Keiko's anus, which was about to burst.

"Plop...plop..." The sound of feces spraying from her anus into the metal bucket on the ground was audible.
Her body, which had been holding back for so long, finally relaxed. Keiko let out a breath and relaxed her body; the fact that she had been defecating in front of her students was
irreversible.

However, as soon as her body relaxed, the contents of her intestines were pushed forward unimpeded. Keiko felt
pressure , and by the time she tried to tighten her muscles, it was too late. "Plop...plop...plop plop..." The feces
came out like a machine gun, even more than before. "Oh, this must be the teacher's lunch." Ihara pressed the shutter repeatedly, the flash going off incessantly

in the room . "Even though she's a beautiful teacher, her poop still smells bad." "Don't say things like that, you'll be punished by heaven. Ihara, make sure to take a clear picture of the teacher's face and anus together. Tajima, come in! " "Yes, do you want me to serve you? I'll wash your buttocks later, Matsushita-sensei, don't be angry, just poop ." Tajima stood respectfully to the side in front of Kuroda. "After you've finished defecating, I'll untie you and then come to my house. I'll throw you a pet welcome party..." "Gurgle...gurgle..." At this moment, Keiko's stomach, which had calmed down, made a strange sound...it seemed...the enema had worked again... Chapter Two: The Pet Welcome Party (Part One) "Woo...woo..." The siren of an ambulance pierced the night, and with a sharp turn, it drove into the city's only hospital, Kuroda Hospital. The hospital doors opened, and paramedics in white uniforms stepped forward to take the injured from the ambulance . It seemed perfectly natural for innocent people to be doing sacred work. But the backyard of this sacred place was a den of demons. Kuroda, a delinquent student from Eisei Academy and the only son of the hospital's director, had his own two-story house in a secluded spot next to his residence in the backyard. In the demon's hall sat four devils and a fallen angel. Kuroda moved his torment of Keiko from Eisei Academy to his home, but the situation remained largely unchanged; Keiko was still naked. Before everyone prepared dinner, Kuroda dragged Keiko to watch a pornographic film . "Tch! What kind of film is this? I bet if Matsushita-sensei starred in it, it would sell like hotcakes ." Kuroda casually played with Keiko's soft, elastic breasts from behind her neck to her chest, but Keiko ignored him, her head bowed. Kuroda, his head bowed, said to Keiko, "My family is quite open-minded, isn't they? This place is exclusively mine; no one can hear me even if I shout loudly. The cricket-teacher, Yoshizawa-sensei, was made to cry tears of joy here by us." Keiko, who had been silent since arriving, softly asked, "Are you satisfied with humiliating me like this? I promise not to tell anyone about today, so let me go back!" " Ah!" Keiko's first words were met with a merciless slap. "Watch your words. At school you're a teacher, but here I am the master. When you ask the master for something, you must kneel down!" Kuroda warned loudly. Keiko covered her flushed face and tears streamed down her cheeks: "That...that's too much." "You haven't forgotten the oath we made in the classroom, have you? If you disobey our orders, we'll punish you however we want. Let me help you remember it. Come on! The pet welcome party officially begins!" "What is this? No, no..." Hearing this, Ihara and Imai grabbed and carried her to a metal frame placed to the side. This was a metal frame used for pull-ups, with adjustable height . "Ah!..." Keiko's hands were tied to the horizontal bar at the top of the frame. Because the frame was too high for Keiko , her shoulders ached, and she could only touch the ground with her toes. "Does it hurt? Then let's try a different position, hmm...how about the frog jump?" Kuroda lowered the frame by a third, making Keiko squat. "Your knees aren't forward, they're to the sides!" Kuroda forcefully pulled Keiko's knees apart, and Imai and Ihara immediately used ropes to tie Keiko's knees to two straight iron bars on the ground. "Don't do this, it's too embarrassing!" Keiko shook her head and cried out. With her arms stretched straight, her already high and firm breasts became even more beautiful, and her lower body was in a half-squatting position with her beautiful legs spread wide, her labia peeking out from her pubic hair. Keiko was tied to the iron frame like this, even more embarrassing than the way she had been tied up in the classroom . "Ha! This is like a position for stepping into a boxing ring, we have to take a picture to remember it." Ihara took out a camera and stepped forward to hold it up. Imai then grabbed her two large breasts from behind and smiled. "No, don't take pictures of this ugly side!" "Teacher, we've already taken pictures of you using an enema to defecate, what's there to be embarrassed about now?"

"Click...click..." The flash relentlessly shone on Keiko, who closed her eyes to avoid
the camera .

"Teacher seems to really like this position; her labia look like they'll leak fluid if you just look at them
."

"No, she's drooling because she can't eat the delicious food. Poor thing, please have some treats
!"

Imai took out a bowl of yellow, paste-like liquid. Keiko didn't know what it was, but she knew it wasn't
good . Imai dipped his finger in the yellow paste and smeared it on Keiko's labia. Then, he used his pinky
to smear the liquid inside her vagina. Not wanting to carelessly break Keiko's virginity, he only applied a small amount inside
, but the coldness of the liquid and the insertion of the hard object already made Keiko uncomfortable.

"Wow! Please don't do this."

"Teacher, please don't refuse our kindness. We need food when we're hungry."

"You can't fight when you're hungry. Let's eat while we watch the pet's butt-wiggling dance." Kuroda led the way,
sitting down .

After dinner, the members of the "Kuroshikai" sat down in front of Keiko, waiting for the yellow, sticky fluid to take effect
. Keiko was initially happy that the boys were sitting quietly beside her, allowing her beautiful body a temporary rest. Sometimes she even
fantasized she would be released when the night absorbed the boys' energy.

Watching the second hand of the clock on the wall tick by, the quiet hall was filled only with the "…de…de…de…
de…de…" sound. The oppressive space and erotic gazes made Keiko feel pressured, her heart pounding
with tick of the clock.

With a beautiful face, a curvaceous figure, and snow-white skin, Keiko, if not for her shameful poses and
icy demeanor, resembled an angelic ice statue. However, even ice melts eventually
. A thin blush rose on Keiko's lifeless, ashen face, and her body reacted inexplicably, making her tense. The cool, yellowish fluid applied to
her genitals changed, its temperature rising to a warm one.

She didn't know what this strange substance was, but it seemed to be livingly eroding her body. The alternating hot and cold temperatures
stimulated Keiko's sensitive vulva, gradually making her feel as if she were being bitten by ants and mosquitoes.

"Ah...ah..." First, her body trembled slightly, her hips swaying involuntarily.

The eyes of Kuroda and the others gleamed even brighter; the main act of the lewd play was about to begin.

"Ah!... It's so itchy..." The pleasurable sensation of insect bites inside her vagina caused Keiko to leak a gush of vaginal fluid,
deepening the pale blush on her face.

"Ah... It's so itchy... Please, please, find a way to stop the itch...!" The increasingly intense stimulation
caused Keiko to lose control, twisting her waist and swaying her buttocks in an arc. These unconscious movements not only
failed to alleviate the discomfort but also caused the yellow fluid, originally applied to her vulva, to seep even deeper,
expanding the affected area and causing vaginal fluid to flow out like a burst dam.

"I never expected the teacher to be such a good stripper. Even if you lose your job one day, you can still make a living as a stripper
." Kuroda lit his cigarette with satisfaction.

"It's so itchy! Please, find a way!" Once her body started twisting, she couldn't stop, her buttocks tracing larger
arcs, the violent swaying splashing copious amounts of vaginal fluid onto the ground. The feeling, worse than death, drove Keiko to
screams. At this moment, she would do anything to alleviate the pain in her body.

"Don't forget your status as a pet. When making requests, address us as 'Master.'" Kuroda approached Keiko
.

"Yes, Master!..."

"Then let me ask you. Keiko, where does it itch?"

He wanted to say something vulgar to make Keiko feel embarrassed, but it was a choice: "It's...it's Keiko's
genitals that are so itchy, please...Master, please think of a solution..." "

What genitals? I don't understand, explain more clearly."

"I...I can't say those things, Master...please don't tease me..."

"Ding...dong...ding...dong..." Two rings of the doorbell interrupted Kuroda's game.

(II)

The night was far from peaceful. A guest arrived at the Devil's Hall, where a pet welcome party was being held for Matsushita Keiko.

The door opened, and standing outside was the expressionless Harukawa Koda. A top student from the school should
be completely out of place in this awful place, but in a place where even the humiliation of a teacher could happen, what was impossible?

"Why are you so late?" Kuroda asked, opening the door.

"Sorry, I was just having dinner..." Harukawa replied respectfully.

Indeed, this was a devil's dwelling; anything nauseating could happen. Kuroda grabbed Harukawa, who was standing frozen in front of the door,
and forcefully kissed him. Faced with Kuroda's forceful kiss, who was a head taller than him, Harukawa looked shy but
made no attempt to resist, letting the same-sex boy tease him with his tongue.

"Come in, everyone's waiting for you."

"Yes." Harukawa wiped the saliva Kuroda had left on his lips and followed him inside.

Harukawa walked a few steps down the corridor with familiar steps, then turned right to reach the door to the main hall. The normally
clear demonic realm emanated a terrifying aura far more intense than usual.

"Ah! Matsushita-sensei?!" Seeing
the disgraceful state of the second most respected person in his life besides his mother—Matsushita Keiko—Harukawa nearly fainted.

(Is it...Harukawa-kun?) Keiko, who had always regarded Harukawa as
her younger brother, was shocked by his arrival and covered her beautiful face with her hair in embarrassment.

"From today onwards, we have one more pet. Harukawa, isn't that great?" He grabbed Keiko's
hair , making her already embarrassed face turn even redder.

The inner pain extinguished all the lust in her body. Before Harukawa, whom she considered family, she uncontrollably
danced a lewd, hip-wiggling dance. Even death would be better than this.

"Teacher..."

Kuroda: "Teacher asked to be a pet herself. That pose was also requested by the exhibitionist teacher herself
!"

"Liar! Teacher isn't like that! You shouldn't have hurt Teacher like this..." Although she didn't know the reason,
Harukawa could guess that the angel in her heart had fallen due to the devil's scheme.

"I'm not lying to you. Here's a pledge that Teacher signed herself."

"Forcing Teacher to write something like this, isn't that too much?"

"Don't pretend to be so proper in front of the teacher. If the teacher knew your true colors, I wonder if you'd still be able to say such
things?" Kuroda gave Harukawa a malevolent smile.

Kuroda then gave the order: "Take off his clothes."

Ihara and Imai grabbed Harukawa, and the frail scholar had no choice but to submit to the thugs' grip, all he could do
was struggle.

All that could be heard were Harukawa's cries of pain; she didn't know what kind of torture he would suffer. Keiko couldn't bear it and closed her eyes.

"Go ahead and watch! Doesn't the teacher want to know what kind of delinquent your beloved Harukawa has become? Open your eyes
and see what kind of perverted behavior this so-called model student can have!"

Although she didn't want to see Harukawa being bullied, Keiko was still concerned about his situation, and she half-opened her eyes to look at
Harukawa . The handsome young man before her, Harukawa, looked no different from any other boy, except that he was wearing
a bra , a fact that truly surprised Keiko.

"Don't strip me naked in front of the teacher!" Harukawa protested fiercely when Ihara pulled down his trousers
, only to find himself helplessly pinned down by Ihara's strong arms.

"This kid gets all cocky in front of the beautiful teacher, actually putting up a fight."

"You should speak like a woman in front of us, didn't we tell you that already?" Ihara said, then
grabbed Harukawa's scrotum hard as punishment.

"Ah! It hurts!" The excruciating pain reminded Harukawa of the discipline he had previously received.

"…Forgive me, I won't rebel again…"

"Harukawa has been our pet for half a year, a senior to the teacher, and we've already trained her to be very much like
a woman."

"Teacher, now look carefully, or open your eyes if you don't want to be beaten."

"Ugh…ugh…" Ihara played with Harukawa's naked breasts from behind, and as expected,
Harukawa, trained by Kuroda, let out a moan like a girl. However, what stunned Keiko most was Harukawa's slightly
protruding breasts—breasts indistinguishable from a young girl's!

Kuroda: "I forged his application form, had the doctor at my dad's hospital inject him with female
hormones ... and also had surgery to augment his breasts."

"But his little penis is still hanging here, it's an eyesore, might as well cut it off."

Imai removed Harukawa's last remaining underwear, revealing his shy little penis, the pubic hair around it already
shaved. Feeling as if a loved one had been humiliated, Keiko turned away, unable to bear looking.

"Teacher, don't close your eyes, why don't we shave yours like Harukawa did?"

Kuroda pulled Keiko's nipples upwards from behind, her entire breasts swaying.

"Wow! I see! I see!" The burning pain in her nipples forced Keiko to submit.

"Although Harukawa's breasts aren't very high, they're still very sensitive. Teacher, take a look..."

Kuroda rubbed Harukawa's nipples with his fingers. The stimulation of her sensitive area caused her uncontrollable lower body to react, and
her developing penis, which had been limp, became erect.

"Teacher, don't look...no..." Her body faithfully responded to the sensations it received, and Harukawa hated this
uncontrollable instinctual behavior.

"Does Teacher know? Harukawa, like Teacher, likes to be played with in front of others. She's an exhibitionist and
a masochist !"

An exhibitionist and a masochist...an exhibitionist and a masochist! ...An exhibitionist...is...(I
am...an exhibitionist...a masochist...?) Every insulting word echoed in Keiko's mind, disrupting her
thoughts, and the lust she had successfully suppressed earlier rekindled. The potent aphrodisiac, unchecked by willpower
, reactivated, causing the dried-up vagina to secrete fluids again.

"Teacher, what's wrong?" Imai asked. "Itchy! Ah...it's...it's itchy again..." Keiko still vividly remembered

the discomfort caused by the unknown aphrodisiac . "No...please help me, it's getting itchier..." "You forgot your tone when you spoke. Don't act tough in front of Harukawa. State your itch clearly." "Don't bully me, I'm going crazy..." "That's why I asked where it itches. Before you tell me, let me let you experience something different." "Is it itchy? Let me give you more stimulation...okay!" Imai's large, fat hand slapped heavily against Keiko's large, beautiful buttocks. "Ouch!" A sharp slap left a bright red handprint on her snow-white buttocks. "Is it good?"... "Still itchy?"... "Is it good?"... Imai seemed determined , the heavy slaps continuing. What should have been a painful punishment stirred ripples within Keiko's heart. With each slap to her buttocks, her lower body thrust forward, simultaneously releasing the fluids from her vagina. And so it continued, secreting and splashing... "Wow! I'll talk! Spare me!" The remaining aphrodisiac inside her vagina was hot, the secreted fluids were cool, and combined with the heavy blows to her buttocks, the confused sensations gradually blurred, making it impossible to distinguish between pleasure and pain. "Please, Master... it's my little hole... my wanton vulva is so itchy, I can't stand it anymore! Please, please help me!" "Harukawa, did you hear that? The teacher is going crazy from the itching in her little hole. Why don't you use this to relieve the teacher's itch?" Kuroda gently stroked Harukawa's penis. "No, I can't do that to the teacher." "Senior! It's such a waste to give the beautiful teacher's virginity to Harukawa!" Imai and Ihara expressed their dissatisfaction. "If you want to train your teacher into an obedient pet, this is necessary. A proud beauty values her virginity most. Today, she's only offering her body because of lust. If we were to deflower her , she might be resentful when she sobers up. But if her virginity is taken by Harukawa, whom she likes, then it's different..." Kuroda explained. "Ah...it itches...please help me..." Keiko screamed frantically. Kuroda: "If you want to stop the itching, ask Harukawa. You said Keiko's vagina is unbearably itchy, come and fix it." "Harukawa, please come and take care of it..." Keiko, consumed by unbearable lust, abandoned her pride and begged Harukawa. “Teacher, I can’t…do that to you…” “You’re so hard…and you still say no…?” Kuroda teased Harukawa’s scrotum.

“It’s a beautiful woman begging you! You’ll be punished if you don’t agree.” … “Let us help.”

Imai loosened the rope binding Keiko’s knees and pulled the iron frame to a suitable height for Keiko.

“Let’s get intimate.” Ihara pushed Harukawa down onto Keiko, making Harukawa’s hands go around Keiko’s back
and tie his wrists, so that their upper bodies were pressed tightly together.

“I don’t want this, untie the ropes…” Harukawa still rationally suppressed his emotions.

“Teacher can’t just stand there, move your breasts closer to stimulate him.”

Keiko, wanting to get a quick solution, did as she was told and rubbed her breasts against Harukawa’s body.

“Teacher… no… you can’t do this…” Every time Keiko’s nipples gently brushed against his body,
the current of pleasure made Harukawa’s body tremble.

"What a slow-witted teacher..." After fiddling with the two naked mounds for a while without any progress, Kuroda impatiently
patted Keiko's buttocks and whispered in her ear, "Hook your legs around her and beg properly..."

Keiko lifted one of her beautiful legs and hooked it around Harukawa, saying as Kuroda had instructed, "Please, Harukawa-
kun, in the classroom we are teacher and student, but here we are naked men and women... and we are both pets, I can't
stand the itching anymore. Hurry! Harukawa, only you can stop the teacher's itch now! Put in more effort!"

Keiko rubbed her lower body against Harukawa, and when her pubic hair brushed against Harukawa's glans, Harukawa's desire was
ignited .

“Harukawa-kun, I’ll do whatever you say… Come on…”

“Forgive me, teacher… forgive me!” Harukawa, being a boy in heat, finally
succumbed to Keiko’s temptation. He moved his penis, trying to find the entrance to her vagina. Although
he had been played with countless times by the members of the Black Society, this was his first time with a woman’s body. His haphazard thrusting couldn’t get in smoothly.

“No, hurry up and get in, or I’ll really go crazy… Not there, a little further down!”
Seeing what she craved right in front of her, Keiko was frantic, desperate.

“This couple is really troublesome, go help them.” Kuroda lifted Keiko’s legs high, while Ihara gripped
Harukawa ’s penis, aiming the glans at her vulva. Because Keiko was taller than Harukawa, her standing position allowed
the penis to slant precisely to the opening.

“Okay…one…two…” Before they even counted to three, Kuroda and Ihara pushed Keiko and Harukawa’s
buttocks , allowing Harukawa’s penis to easily penetrate Keiko’s vagina.

“Ah!” Both of them cried out in pleasure at the same time.

Keiko, who was experiencing a penis for the first time, was still savoring the pleasure of the glans suddenly thrusting in. Harukawa’s penis
was small, but it was very comfortable for a virgin’s narrow vagina.

Kuroda asked, “Teacher, is it really okay?”

“Yes…yes…Harukawa-kun, please continue.” Keiko was truly enjoying herself.

“Ah…no…I can’t…Teacher, I…” The already narrow vagina was unbearable, let
alone Keiko’s vagina, which was sucking and releasing Harukawa’s glans with each thrust, trying
to absorb all of his essence. Even the most skilled lovers would find the virgin's flesh unbearable. Harukawa, after just a few rubs, showed
signs of near collapse.

"Ah..." Harukawa shuddered several times with all his might, and after only one thrust, his entire penis, inserted into Keiko's vagina
, released his semen.

"No, I can't ejaculate yet...!" Keiko abandoned her pride.
The pleasure she had endured through all sorts of humiliation turned to intense disappointment when she felt semen leaking into her vagina.

"Harukawa surrendered so quickly; the teacher's lust will burn even brighter. Let's take Harukawa's place."

Kuroda stood satisfied in front of Keiko.

"Please, I really can't take it anymore! Whoever it is, please come and penetrate me!" As soon as the penetration stopped, Keiko
's vulva itched again.

"What a lecherous teacher, huh? Let's gang rape you to your heart's content."

They lowered Keiko from the iron frame so they could rape her as they pleased, then tied Harukawa to the frame in her place. Kuroda took out a small
rope, and Keiko obediently put her hands behind her back, letting Kuroda tie her wrists. Keiko didn't care
what they wanted to do; she only hoped the boys would satisfy her physical needs.

"Please...please stop my itching, okay?" Keiko twisted her already aching buttocks, her thighs still
bearing traces of virgin blood from her vulva.

Kuroda didn't respond, so the others didn't dare to do anything rash.

"Yes...I'm begging you as a pet." Keiko was gradually realizing Kuroda's intentions.

Keiko performed a deep kneeling bow to the students, kneeling on the ground and burying her face in it.

"I, Matsushita Keiko, am an exhibitionist and a promiscuous woman. I love sex. Now, please
gang rape me!" Whether it was the influence of drugs, her inner lustful instincts, or the result of Kuroda's training, Keiko
shamelessly uttered these vulgar words.

Kuroda: "Alright! Since you've asked, I'll rape you. The bedroom is upstairs; she'll go first."

"Hurry, hurry up..." Keiko endured the itching in her vagina, her hands bound behind her back, half-limping, half-stumbling up
the wooden stairs.

Kuroda secretly pressed the button on a hidden tape recorder. The others looked at Keiko's disheveled figure and exchanged knowing smiles.
It was obvious that a conspiracy was brewing.

On the large bed, Keiko had already assumed a welcoming posture, her wrists bound behind her back with rope, her legs
spread wide. By this time, Keiko was a woman at his mercy, but Kuroda still used ropes to tightly
bind her ankles to opposite corners of the bed, stretching her legs into a wide V-shape to satisfy his sadistic desires.

"Hurry...hurry up and insert it, it's getting itchier..." Keiko didn't care about Kuroda's rough treatment;
all she craved was a male organ to soothe the agitation inside her. Her vaginal fluids flowed from her opening onto the sheets.

Kuroda: "This is something our teacher willingly allowed us to rape; we never forced you." Kuroda straddled Keiko
.

"Yes, it's Keiko who wanted Master to fuck me, hurry...please fuck me quickly."

"Where do you want to fuck me?" Kuroda pressed.

“Little hole… insert into Keiko’s lewd little hole…”

“Okay!” Kuroda sat cross-legged on the bed, picked up Keiko, and held her tightly with both hands, his glans pressing against her
vulva. As soon as he loosened his grip, Keiko sat on Kuroda’s lap, her plump vulva swallowing his erect
penis whole.

“Okay!…” His penis, much larger than Harukawa’s, plunged
smoothly . The even larger penis plowed through the newly deflowered vagina, and Keiko convulsed before ejaculating,
experiencing even greater pleasure than Harukawa’s penetration.

Overwhelmed by the intense stimulation and release, Keiko lost her balance, falling back onto the bed, but
her lower body remained connected to Kuroda.

“Mmm… mmm…” Keiko’s body continued its orgasmic response, her chest heaving, soft moans escaping her lips,
her vagina still tightly gripping Kuroda’s penis.

Kuroda, his penis still hard inside Keiko’s vagina, intended to thrust or change positions. He
remained seated, carefully observing the beautiful teacher’s seductive energy, while also relieving
the pleasure on his glans.

"Teacher is amazing! Just one thrust and I felt the urge to ejaculate..."

"Ah..." As Keiko's vaginal muscles loosened, Kuroda thrust his
hips maintaining the sensation of her orgasm. Then, just
as Keiko's body began to relax, Kuroda would thrust several times, keeping her arousal constant. Harukawa

used his penis to break her hymen, and Kuroda gently inserted his, giving Keiko a painless first time and allowing her
to experience the pleasure of sex. Under the continuous orgasms, Keiko couldn't withstand the constant stimulation and, feeling dizzy and lightheaded
, half-conscious.

Having been gripped and sucked by her vagina for so long, Kuroda couldn't resist. He lifted Keiko's legs and
thrust forcefully into her vagina dozens of times, ejaculating his passionate semen into the unconscious Keiko's vagina.

“As expected of a lewd female teacher, even though she’s unconscious, her cunt is still sucking in semen…” Kuroda withdrew,
and a mixture of aphrodisiac, vaginal fluid, and semen flowed from her vagina.

Keiko, already half-conscious, lay paralyzed on the bed, unconscious. Imai pushed Keiko several times but couldn’t wake her
. The remaining men, who hadn’t yet ejaculated, became tense.

“I can’t hold back! Let’s do it like a necrophiliac!” Imai climbed on top of Keiko and began
to fuck .

“Ah! So tight…” Before long, Imai couldn’t help but ejaculate.

Afterwards, Ihara also couldn’t withstand the tight cunt and quickly ejaculated.

Unwilling to accept defeat, Imai immediately attacked Keiko again after Ihara withdrew. He placed Keiko's legs on his shoulders
and pressed his entire body down on her, a position that allowed for deep penetration. Confident that his recently ejaculated penis
wouldn't relentlessly thrust into her vagina.

Under the frenzied penetration, Keiko's body gradually regained consciousness and responded, releasing more vaginal fluid.
Regaining consciousness and opening her eyes, she saw her student's face before her, her legs bent over her chest, her vulva facing upwards to receive
the penetration.

"Is it not over yet...?" Having fully regained consciousness after the aphrodisiac wore off, Keiko turned her face to the side, her vagina still
leaking fluid, but her demeanor remained indifferent.

"Teacher, aren't you happy even when I penetrate you?" He had hoped to experience extreme pleasure upon Keiko's awakening, but instead, he
was met with a blank, expressionless body. This was no different from the previous necrophiliac treatment, leaving Imai feeling resentful.
He thrust harder a few more times to show his dissatisfaction.

"So, Teacher only feels happy when aphrodisiacs are applied, you wooden beauty? Well, I'll give you the drug then."

"No, no…" The thought of being drugged again was unbearable.

"Then why does Teacher seem unhappy?"

"No… no, it's probably because I just woke up…"

"But Teacher's attitude just now hurt me. You have to work harder to make me feel good…"
After withdrawing his penis from her vagina, Imai lay down on the bed, his still-erect penis standing proudly before Keiko in a show of defiance.

“Teacher! Sit down quickly, don’t keep me waiting, and don’t forget you’re a pet…”

Keiko knew that if she angered them, she would be subjected to even more brutal abuse. Since her fate of being raped was
unavoidable , Keiko straddled Imai and inserted his penis into her vagina.

“Don’t be lazy, rock your hips back and forth,” Imai instructed.

“Yes.”

This time it was a female-dominated position, and Keiko easily achieved pleasure. Keiko began to learn how to use
the penis inside her vagina to satisfy herself. When she wanted to thrust all the way in, she would thrust her hips forward in one go; when she wanted to rub against the walls of her vagina, she knew to
twist her hips.

"Ah...oh..." Ignoring her pride, she decided to indulge in pleasure. Keiko moaned ecstatically, her body
swaying , her large breasts rolling up and down, her buttocks swallowing and releasing his penis, drawing out copious amounts of her juices.

Imai reached out to grab her dazzling breasts, but they were too large and the vigorous movements made it difficult for
him the wanton beauty to escape.

Unable to catch them, Imai simply buried his face in Keiko's chest, letting the swaying breasts hit his face. Keiko
's seductive allure stimulated his senses, the rapid rhythm, the soft sensation on his glans...

"Ah...I can't take it...I'm going to cum again!" Imai ejaculated into Keiko's vagina for the second time.

“Teacher, you can’t just be nice to Imai, you have to give me pleasure too!” Ihara pulled Keiko to the bedside and raped her in
the missionary position…

Afterwards, each of the young and energetic boys raped Keiko twice more before stopping.

Having been violated more than ten times on her virgin night, Keiko lay exhausted on the bed, the rope binding her wrists
still in place, breathing intermittently, her genitals covered in copious amounts of vaginal fluid and semen, her trembling naked body revealing sexual
satisfaction.

“It’s late, Imai, go find a taxi. We can’t let the teacher stay here overnight; it’s not
the right … Hey, Ihara, did you take any pictures of the teacher’s current lewd behavior…” Kuroda instructed everyone
to clean up afterward.

“Teacher, are you satisfied? Get up.” Kuroda kicked Keiko’s buttocks.

Kuroda: "You need to wear this skirt to school tomorrow, remember that!"

Keiko, exhausted from being played with, tidied herself up, took the short skirt Kuroda had given her, and
quickly left the lecher's room.

Keiko let out a sigh as she stepped out of the room. The day's events felt like a dream; her mind was blank.
She stood in front of the door for a moment, then glanced back at the still-lit brothel. Terrified, Keiko hurriedly got into
the taxi Imai had called and drove away.

Chapter Three: The Classroom Exhibitionist (Part One)

The nightmarish night passed. The next morning, Keiko asked for leave from school, saying she wasn't feeling well.
Cute , beautiful as she matured, Keiko had received love and care from those around her since birth. She
had many suitors during her school years, but they were all gentle. She learned about the beautiful world from books, but when the sudden violence of the previous day occurred,
she couldn't handle it. Keiko Matsushita remained hidden under the covers, her gaze blank, not thinking about the future.

"Keiko, Kuroda's student called..." Keiko's elderly mother opened the door, her
movements revealing paralysis in her lower body.

"What?" Keiko snapped out of her daze, already anticipating that Kuroda wouldn't let her off easily.

She put on her morning coat and stood before the phone, hesitant. The devil's intentions were obvious, but his actions
were unpredictable. If she didn't answer, she didn't know what kind of revenge they would take. She closed her eyes, took a deep breath, and forced herself
to remain calm as she picked up the receiver…

“Yes, this is Keiko,”

she said, deliberately lowering her voice so her mother wouldn’t hear. “We heard you were sick, teacher. Are you better now? Your photos are developed, and we’d like to come see you,
” Kuroda’s voice came through the receiver.

“No! No need. I’ll definitely be able to go to school tomorrow.” Keiko knew those devils had ill intentions, so she could only
promise to appear tomorrow, hoping to dissuade them from forcing their way in.

"Alright, remember to wear the skirt I gave you, and the top should be a front-opening style. Most importantly, you can't
wear underwear...

" "No... at least... let me wear panties!"

"Alright, but you have to wear seven-colored panties."

"...I...I don't have any."

"Then I'll give them to you. You're not allowed to wear panties to school. I'll give them to you later. You also have to wear
high heels . If you don't want me to publish the photos, remember to do as I say, otherwise... ha!"

Kuroda's cold laugh chilled Keiko to the bone.

"Yes, thank you for calling." Seeing her mother peek out, Keiko quickly agreed and hung up.

(…………) Keiko stared blankly at the phone…

“What a good student, calling to check on me…” Her mother, unaware of the situation, was pleased to see her daughter so well-liked by
her student .

“Yes…yes.” …“Mom, I’m going to school tomorrow, wake me up on time.”

“Are you feeling better?”

“Yes, I’ll be fine after a day of sleep.” Forcing a smile, Keiko didn’t want her mother to worry.

Her mother was getting old, and the family burden was heavy…she couldn’t quit her job. And besides, indecent
photos had been taken of her; if they moved, who knew what they would do…call the police! …Would that work?

Keiko spent her days pondering a way out.

Time…it couldn’t be stopped; the next sunrise was just around the corner. Unable to find a solution, Keiko could only take things one step at a
time.

Following Kuroda's instructions perfectly, Keiko wore a white, front-opening blouse. Because she wasn't wearing a bra,
her breasts were clearly visible, which she covered with a suit jacket. Her high heels made her long, beautiful legs even more dazzling. But
what attracted the most attention as she walked was her incredibly short, provocative skirt, almost revealing her buttocks with every step
. A gentle breeze blew against her exposed vulva, revealing a seductive allure beneath her gentle demeanor. Every
passing would turn back and stare with lustful eyes.

It was rush hour, and the train was packed.

A unique feature of Japanese trains is the well-known pervert, and the beautiful Keiko was always on edge, squeezed
among . She was constantly subjected to lewd stares from men, and now, trapped in the crowd
, she gripped the handrail tightly with tense hands.

Squeezed in the crowd, her body kept bumping into each other, but the sensation of being touched on her buttocks felt strange. She felt as if
a hand was gently caressing her, but the timid Keiko ignored it, hoping it was just her imagination.

The weight on her buttocks deepened, and Keiko was certain it was a hand on her buttocks, because five fingers were
deeply embedded in her flesh.

(Is...is he a pervert?) Keiko seemed flustered. Although she was a well-educated teacher, she was slow
to react . She gently twisted her buttocks in an attempt to escape, but the lewd hand withdrew upon encountering resistance, and Keiko felt
relieved.

(Hmm...) The hand returned, and its action was even bolder, inserting itself into her inner thigh.

(Oh no... they'll find out I'm not wearing underwear...)

Seeing that Keiko didn't react, his hand became even more brazen, reaching upwards. When he touched Keiko's pubic hair, he knew that the
seemingly beautiful woman was actually a slut. Without any hesitation, he pulled up her short skirt, partially exposing her buttocks.

"What should I do...? If others notice, they'll see my exposed buttocks..."

Feeling that the owner of her buttocks had no intention of resisting, his shameless hand touched her anus without any politeness.

(Ah... no...) Because of a momentary lapse in judgment, Keiko found herself in a situation of being played with. Sensitive areas were being
teased, causing her to grip the handrail even tighter. Her lower body, defying her will, secreted its own juices in pleasure…

(Ah…am I really an exhibitionist?…Being played with in this crowded train, my body is even
getting itchy and sensual…) Feeling Keiko's wetness, his lewd hand moved to attack her vulva, using his index and ring fingers to part her
delicate labia, his longest finger, the middle finger, to attack her clitoris.

His middle finger vibrated rapidly against the pearl-like clitoris, trying to make the beauty before him even more wanton. Her juices
flowed continuously throughout the half-hour journey, too much for his teasing hand to handle, staining Keiko's thighs.

“Ding…ding…” The train was nearing its stop. Keiko took a deep breath, waiting for the doors to open so
she could escape the pervert behind her, pulling her skirt back up, and dashing out of the train.

Without looking back, Keiko walked away from the station in one breath. The lustful fluid on her legs evaporated in the morning sun, filling the air with
a sensual scent.

(II)

"Thump...thump...thump...thump..." Keiko's high heels echoed throughout the quiet teachers' room. Her
provocative miniskirt attracted the attention of her colleagues, and her eye-catching outfit drew sidelong glances from the male teachers. One of them was so stunned that he spilled
his tea.

Although Keiko had been stared at by people along the way, she felt embarrassed because these were her acquaintances.
She quickly returned to her seat.

"Oh, Ms. Matsushita is so brave! As expected of a young beauty, she actually wore such a miniskirt." The nosy,
ugly female teacher, Kanda, said curiously.

"I know you're a trendy woman these days, but don't forget this is an all-boys school. Don't be too provocative to the boys."

The speaker was Yokota, sitting next to her, now the homeroom teacher of Class 5, Grade 3, which comprised the worst-performing students in the entire grade.

The teachers in the classroom whispered amongst themselves, discussing Keiko's striking outfit.

Her short miniskirt struggled to cover her large, round buttocks, and her sitting posture had pulled the hem up even higher
; just two more centimeters and her vulva would be exposed.

A pair of lustful eyes were fixed on Keiko's snow-white thighs; the owner of those eyes was none other than the slightly wicked-looking
Yokota.

"Good morning, teachers. Excuse me, I came to see Mr. Matsushita. Sorry to bother you." Kuroda's appearance interrupted
the private discussions about Keiko.

"Mr. Matsushita, we were worried about you when we heard you were ill yesterday. This is a small token of our appreciation." Kuroda
placed a paper bag on Keiko's desk.

"Goodbye!" Kuroda bowed respectfully to Keiko and left.

Kanda remarked, "That's quite polite. Unlike the delinquent who chased after teachers with a piece of southern landmass half a year ago. Yokota-sensei,
you've really done a good job teaching him!"

"But he's still not as good as Matsushita-sensei. He received a gift so soon after arriving." Yokota's gaze kept lingering
on Keiko's legs. Kuroda

's behavior caused the teachers to refocus their conversation on Keiko, whispering amongst themselves . Yesterday, Kuroda said he would wear seven-colored underwear. Although the paper bag was tightly wrapped, Keiko already guessed what was inside . Reaching the restroom specifically for female employees, Keiko opened the bag and reached inside; sure enough it was underwear. "How...how could this be!...Wasn't it supposed to be seven-colored underwear?" What was pulled out was a pair of underwear with thin straps on the side, and most alarmingly, the fabric covering her private area was a slightly sheer black silk. "Should...should I wear this?" Just as Keiko stared dumbfounded at the sexy underwear, a photograph fell out of the paper bag. Keiko picked it up. The person in the photo was familiar yet strange: familiar because it was herself, and the photo clearly showed her face; strange because of the grotesque image of her being lifted up by a student to defecate— she couldn't believe she could be so repulsive. The shameful photo reeked of Kuroda's threats! Class 3-5 was in the second period today. Keiko walked slowly down the long corridor to the classroom at the very end. Her hand hesitated on the doorknob for a moment, then she mustered her courage and pushed the door open forcefully. The students, who were never quiet before, were so quiet today that Keiko was uneasy. The atmosphere was different, and the environment had changed. The teacher's desk was gone, leaving the platform empty. "Where did my desk go?" Keiko asked. "It was a shame it was blocking the teacher's beautiful legs, so I moved it," Kuroda said, standing up and giving his rude reason. The other students took it as a joke and joked around... Agreed... No objections! The classroom became noisy. Faced with the students' unruly behavior, Keiko was helpless, especially since it was Kuroda's doing. "Alright, everyone, quiet down, it's time for roll call..." "Abe-kun?" "Here!" "Watanabe-kun?" "Here!" "No one is absent today, continue with last week's class." With great difficulty, he managed to take attendance amidst the chaos. "Last lesson was about..." Keiko opened her textbook, preparing for class. As her eyes inadvertently peeked at Kuroda for any inappropriate behavior, Kuroda snapped his finger at her, signaling her to come over. "Iida-kun, read this passage from page 20, line 3..." Keiko casually walked to a student in the third line to give guidance, as this was the path to Kuroda, who sat in the back row. "Begin reading," Keiko said calmly, turning and walking towards Kuroda. Keiko stopped beside Kuroda, glancing around occasionally to see if any other students were looking at her. Kuroda suddenly and rudely pulled up Keiko's skirt, checking if she had put on . Keiko was so startled she almost fell off her textbook. She looked back, thankfully the other students were also looking at their books and hadn't noticed Kuroda's actions. What was revealed was her lower body clad in see-through underwear. Although the fabric was deep black, the triangular patch of black pubic hair still revealed an equilateral triangle shape. The thin fabric only covered the most important part, and the shape of her vulva was clearly visible. "Good!" Kuroda was very satisfied with Keiko's distinctly black and white body; this was also his masterpiece. He grabbed Keiko's collar and pulled her upper body closer, unbuttoning her top to reveal her snow-white cleavage. This also revealed that Keiko had obediently chosen not to wear a bra. Keiko pleaded softly, "I didn't wear a bra as you asked, please don't do this here..." "I'm just serving the exhibitionist teacher. If I don't expose my body, the exhibitionist won't get any pleasure ..." "The skirt straps should be raised above your navel..." Taking advantage of Keiko's inattention, Kuroda pulled up the waistband of her short skirt . "Go back to the platform." Kuroda patted Keiko's buttocks. A large expanse of her breasts was exposed, and the raised skirt revealed the semi-circular curve of her buttocks, with a centimeter of her cleft showing . Keiko walked forward nervously, her body swaying as if she were about to fall. Kuroda patted the student in front of him who was still looking at his book, pointing out the impressive sight before him. "Hey..." Messages circulated among the students, and everyone noticed Keiko's seductive behavior. Her deliberately slow, deliberate steps, intended to avoid disturbing the students, ironically prolonged their viewing time. The boys on either side even bent down to peek under her skirt after Keiko passed. Reaching the raised teakwood platform, her perfect buttocks became even more defined, especially the deep cleft between her buttocks and long, beautiful legs, which became the students' focus. "Wow! We saw everything…" "What's going on…?" The whole class started to jeer, and Keiko dared not turn around. Kuroda: "Teacher, how can you teach without turning around?" Keiko understood the command in Kuroda's words, took a deep breath, and turned to face the students. "Wow!…Great…" After a round of exclamations and cheers, there was a sudden silence as the students all focused their attention on…

Look at Keiko's body. Kuroda had pulled open her blouse, revealing a third of her large, snow-white breasts, and
sweat seeped from her deep cleavage. Beneath her miniskirt, her smooth thighs pressed together, revealed black
pubic hair, the color of which was indistinguishable—either underwear or pubic hair.

The air seemed to freeze for a moment; everyone was like motionless plaster statues, frozen in this alternate dimension,
only the sound of heartbeats remaining. Keiko… was nervous; the students… were excited.

“Teacher… your… your blouse is unbuttoned…” a dazed student, completely bewildered,
gave Keiko a silly reminder.

“Oh… yes.” Keiko tried to pull her blouse back up.

“Cough! Cough!” Kuroda coughed twice as a warning.

Keiko's hand, which had been pulling at her collar, stopped. After meeting Kuroda's gaze, she pulled her collar back into place.

"…Teacher…it feels so stuffy…I'm sensitive to heat…so I'm just getting some fresh air…" Keiko tried to
explain.

"If you're so sensitive to heat, why don't you take off your jacket and go to the window for some fresh air!" Imai said loudly.

"Well…that's fine too." Keiko took off her suit jacket and placed it on the back of the chair, opening the window frame as if to cool off.

"Ah…how embarrassing…am I really an exhibitionist?" The cool breeze blowing against Keiko's bare body brought
her a refreshing sensation.

Nagano: "Teacher, showing off your beautiful body is great, but you still need to teach." "

Yes...yes! Then, Shimonaga-kun, continue reading."

Nagano: "Teacher, let's be fair. Let the students in the back rows also appreciate your beautiful body. Please
pace back and forth in the classroom!"

Nagano, a member of the *Kuroshikai*, gave the order, and Keiko, unable to disobey, began walking into the classroom.

"Where are you all looking...? Look back at your books..."

The students ignored Keiko's words, secretly peeking when she couldn't see them.
Even the students couldn't stop after a couple of sentences, intently staring at their beautiful teacher's body.

Walking back and forth among the forty students, knowing everyone was looking at her, she
could look forward to avoid eye contact. The classroom fell silent again. Keiko felt as if she had stepped into a
pack , ready to devour her at any moment, obediently displaying her perfect body. With each step, she
swayed her hips from side to side, sweat pouring down her face, soaking her black stockings and making them almost completely transparent.

Although only a small portion was visible under her short skirt, the shame gave Keiko a thrill of exhibitionism. Her high heels
supported her almost collapsing body, the crisp rhythm causing her large breasts to
bounce . The students' eyes followed the rise and fall of her breasts, her white silk top, now soaked with sweat
, revealing the shape of her breasts, highlighting her nipples, making them dizzying to look at.

"Ding...dong...ding...dong..." Like a life-saving bell, the sound jolted Keiko back to her senses.

"Ah!...Class...is over..." Keiko quickly straightened her clothes and left the classroom.

"A quarter to a quarter... A quarter to a quarter... Wow... Shh... Hazel!..." After a long silence, Class 3-5
erupted in boisterous cheers. The boys danced with joy, jumping up and down or throwing their books into the air to
release their pent-up desire and energy.

The members of the "Black Society" were pleased to see this. Today, besides giving Keiko a lesson on physical exposure
, they had successfully cultivated and aroused the bestiality and sadistic tendencies of the other students.

When Kuroda and the others realized that the beautiful female teacher was beginning to turn into an exhibitionist, they tormented her even more each day...

Today, Keiko's class in Class 3-5 began again. As usual, at the beginning, Keiko would secretly
go to Kuroda's side to await the day's instructions.

"Remember, when you hear my signal, you must do what I just told you, understand?"

Her short skirt, black stockings, and open-fronted top remained unchanged. Keiko, after listening to Kuroda's instructions and
mentally nodded shyly.

"As expected of a clever teacher. Okay, let's go!"

Keiko, as if conducting a normal lesson, wrote the topic on the blackboard with her back to the students…

"…Because of this… therefore, this sentence is…" Keiko diligently wrote
the explanation .

"Why is this happening…? Is today different?…" Having become accustomed to Keiko's usual
display , some students became restless and agitated when their teacher showed no reaction.

"Ahem!" Kuroda seized the opportunity to give the signal.

Keiko remembered Kuroda's orders:

(1. After hearing my signal, the teacher will drop the textbook he's holding...) Keiko pretended to accidentally
drop ...

(2. At this point, you must bend down to pick it up. Remember, keep your legs straight and spread apart, absolutely do not bend them
...) Keiko straightened her legs, bent down to pick up the textbook, her miniskirt couldn't
hide her , revealing her round, fleshy thighs. The thin straps and small triangle of her panties could only cover her anus and
vulva. Between her spread legs were two huge breasts hanging upside down,
appearing even larger because of their upside-down position.

"Wow..." The students snapped back to attention the moment Keiko bent down. The sudden glimpse of her exposed
skin caused some of the students who saw it to jeer.

"What's going on...?" the students who had missed it asked the others.

"Please...quiet...class begins..."

"Ahem!" Before Keiko and the others could even compose themselves, Kuroda gave the signal again.

Having learned from the previous experience, performing the same action became easier this time. Keiko
dropped her book again, knowing that the faster she completed the action, the less time the students would see it, so
she quickly picked it up.

"See?...that's it..." This time, many people noticed Keiko's actions,
causing an even bigger commotion.

"Quiet...quiet down, the answer is..."

"Ahem!"

Before the coughing subsided, Keiko dropped her textbook again, a sign that her body had adapted to the signal and that she was mentally
prepared .

"Here we go again..." The other students were also beginning to get used to Keiko's actions.

Keiko bent down again, intending to get up as quickly as possible, but this time it didn't go smoothly. Because of the tightness...
Zhang's condition and the repeated large movements had exhausted her strength, making this bend even more difficult. Her unbuttoned
blouse, with the repeated bounces of her breasts, had already opened wider and wider, now revealing her pink nipples
. Keiko had to grab the wooden edge of the blackboard to stand up again.

"…See it? It's…it's a nipple!" The students murmured amongst themselves before quietly falling silent,
realizing this was part of their teacher's performance that day, and they needed to concentrate, not wanting to miss a single
second of the exciting moment.

The entire class was silent; even without looking, Keiko felt everyone's gaze fixed on her.

"Forty students are watching me…" Extreme nervousness made Keiko forget to pretend to teach; her
trembling hands held the chalk and textbook, her rapidly beating heart counting down, waiting for the next signal.

The whole class fell silent, waiting. Since Keiko hadn't made a move, some
students tensed up, clenching their sweaty fists.

Keiko didn't want Kuroda to give the signal again, didn't want her body to be further humiliated by the students, but her uncontrollable
body was ready to obey at any moment. The exposed lust aroused Keiko, and her genitals
seemed to be going crazy waiting for the signal. A sensation, like a urge to urinate or an orgasm, surged through her vagina… This made
Keiko even more tense, contracting her vaginal muscles tightly.

"Ahem!" Kuroda gave the signal just as everyone was reaching their peak of tension.

"Shh… it's coming…" Keiko's body, relieved by the signal, naturally dropped her textbook
to the ground again… At this moment, the long-awaited little pervert stood up impatiently, craning his neck to see the beautiful sight he so desperately wanted.

Keiko bent over, a familiar movement she had performed many times before, but this time the sensation
was vastly different. The physical strain of waiting was relieved by the liberation after bending over, and this comfort made Keiko lower her
guard. The thought of spreading her legs to show her breasts, which had already fully spilled out, and the prospect of her two
pink nipples being exposed to the entire class intensified the shock to her vagina.

This was quite a shock; it was too late for Keiko to regain her composure and resist. The bending at the waist and
the spreading activated the muscles of her genitals, and combined with her momentary relaxation, a torrent of pleasure surged from
her vagina.

This was what had previously made Keiko feel the urge to urinate—a suppressed gush of vaginal fluid that had uncontrollably
sprayed onto her underwear. How could thin, delicate panties possibly contain such a torrent? A small portion, propelled by
the force of the fabric, managed to break through the silk and spill onto the teacher's platform; the rest simply flowed from the sides of the panties, down the thighs, and
onto the floor. The silk panties were now completely soaked and transparent, the vaginal fluids adding
a layer of , radiating a captivating heat under the sunlight!

The lewd scene was too much for the young students to bear. Some, after a couple of shudders,
ejaculated inside their school pants. This feeling, like a wet dream, was even more wonderful than in a dream. Some even ejaculated
twice . Some secretly hid under their desks, masturbating in front of the beautiful Keiko.

(Look! ...Those who like to look, look...) Keiko didn't get up for a long time, because she couldn't think of
a way to face the students, and besides, her body, exhausted from ejaculation, lacked the strength. Since they couldn't think of any other way, they simply
grabbed the wooden frame of the blackboard for support, continuing to expose their lewd buttocks high, hoping the bell would ring soon.

The time before class ended was enough for the students to masturbate a second time under their desks. While everyone was in high spirits
, tears welled up in a dark corner of the classroom…

(I'm sorry, teacher, they harmed you because of me… The elegant Matsushita-sensei was threatened and did
something shameless… It's all my fault…) The unassuming Harukawa Koda was secretly sobbing in the dark corner…

(I'm sorry… teacher… I'm not human…) Keiko's lewd posture made
Harukawa, who had tasted Keiko's body, feel even more deeply. Harukawa saw that his pants were wet; he had ejaculated earlier without being able to stop himself
. Harukawa felt even more ashamed because he had also ejaculated after seeing his teacher, who served him like a younger brother, being humiliated…

“Hehe! Are you enjoying being exposed? It's time to move on to the next step…” Kuroda happily calculated in his heart… For
Matsushita

Keiko, the classroom of Class 5, Grade 3 at Eisei Academy was the source of her nightmares. Two weeks ago,
she was forced to take shameful photos here by delinquent students to be used as blackmail. Two hours ago, she was again humiliated in front of forty students in the same place, orchestrated by Kuroda
. Reluctantly, she now had to walk helplessly down the corridor leading to this nightmare
classroom , step by step, heading back towards that nightmare factory.

Recalling the shameful scene two hours earlier, waiting for the bell to ring, Keiko fled
the classroom and hid in the women's restroom. She locked herself inside and wept for her pitiful fate.
After locking herself in for over an hour, she heard a knock on the door:

"Matsushita-sensei? Are you alright? You've been in there for a long time, are you okay?" The concerned greeting came from the devil
's mouth; it was Kuroda's voice.

"..." Keiko was too afraid to respond.

"Matsushita-sensei?...I hope you're alright!...I'm coming in!"

"No...I'm fine, just a little unwell, I'll be fine in a bit..." Keiko
answered hastily, having no other choice.

"That's good, I was so worried!"

"I'm fine, class is over, you can go home now, don't worry."

"Not yet, teacher, don't you remember today was our class's after-school self-study session? You came
to observe last time, have you forgotten?"

"No, how could I..." Of course, Keiko had dreamt of such a shameful thing countless times.

"That would be best, since you're very popular, I'd like to ask you to come again today."

In the classroom during the day, students might have some restraint, and their insults would have a limit. But in the
quiet, empty environment after school, who knows how wild they might become?

"Oh no, I want to go home and rest early."

"Don't worry, teacher, you won't have to do anything strenuous. Just sit aside and watch."

"This…" Keiko was still trying to find an excuse to decline. Suddenly, a small stone wrapped in paper was thrown
into the toilet through the ventilation window… It was easy to guess that this was Kuroda's doing. Keiko unwrapped the paper from the stone; it was another
unflattering photo of herself. Keiko understood Kuroda's intention perfectly.

"Teacher, are you really not going? Then I'll just hand out your beautiful photo to comfort those who are looking forward to your visit
!"

"No! ...I'll go. Is it really just for a quick look?"

"Of course, I wouldn't lie to my beloved Matsushita-sensei."

**********************************************************************

Even if the pace is slow, the destination will eventually be reached. Since Class 3-5 is the worst
class in the school, its assigned classroom is the worst and in the most remote corner. Keiko passed by the corner in front of Class 5 and
encountered the school janitor,

Tajima. "Oh, Matsushita-sensei, hello. Are you here to observe extracurricular study again? You look so beautiful in that miniskirt! The whole school
is talking about it."

In front of what is arguably the least visited classroom in the entire school, Tajima unceremoniously stared at Keiko's beautiful legs.

"Please, keep what happened last time a secret."

"Of course I will. I'll keep

watch today too, don't worry." "No need, I'm just going to check."

"Oh, that's a shame. I was hoping to help the teacher clean up her mess... But today is really strange. The classroom
floor is covered in filth, and the teacher's desk smells of my beloved teacher..."

(What? He knows about today's events too?) Keiko didn't want to argue with him, so she avoided Tajima and pushed open
the classroom door.

"Clap clap... clap clap..." The students in the classroom clapped to welcome Keiko. There
were many more people than last time, probably twenty, but Kuroda had said he wouldn't make her too uncomfortable, so she minimized
her worries .

Sitting in the crowd was Harukawa Koda, completely naked, head bowed and silent. Keiko was also struggling to keep her own body in check,
so much.

"Matsushita-sensei, in this hot summer, why don't you expose your chest to cool off? Haruka is already so hot he wants to strip naked,"

Nagano said.

"Don't worry about me, you can start your studies. Kuroda, who are these people?"

Keiko did as he was told, unbuttoning her blouse to reveal her cleavage. Having performed this body exhibition in the classroom
many times , Keiko no longer felt too embarrassed to expose half of her breast. With a very natural posture, Keiko sat down in her
chair.

"These are all members of the 'Black Shikai'."

"All of them?...So many?"

Kuroda explained, "Yes, because the after-school tutoring is so popular, it
attracts . Last time was the teacher's welcome party, so only the executives attended."

"We also set a learning theme each week. First, there was anatomy class, then shaving and whipping
classes... This week, we're starting on homosexuality. It's very convenient
because . The rapid increase in 'Black Shikai' members can be attributed to
these pets who represent female bodies..."

"How could this be?..." Knowing Harukawa's long-term suffering pained Keiko.

"Teacher, just sit there and watch. That's what I promised you. Now, please let the student council member
Nagano preside over this week's new project in front of the school-wide admirer, Ms. Matsushita."

Nagano: "Harukawa, aren't you going up to the platform?"

"I can't... in front of the teacher."

"No? The teacher came specifically to observe; you can't be rude. Besides, she's not an outsider to you..."

"Ah!" Nagano pulled hard on the rope, dragging Harukawa away. The rope was tied to Harukawa
's wrists behind his back.

"This can't be! It's too cruel!" Seeing Harukawa suffer, Keiko couldn't help but rush out to stop him. But Kuroda
immediately blocked her way.

“Although I am a teacher, bystanders are not allowed to interfere.” Nagano: “You have to say
your lines . If you don’t want to, I can have the teacher do it for you.”

“No, I will say it.” This was the only thing Harukawa could do to protect Keiko.

“I, Harukawa Koda, am a half-male, half-female transvestite. I love being bullied and abused by my classmates. Please
love this perverted person.”

“That’s not enough. And it’s not love, it should be toying with. Continue!”

“I… I have something unsightly in my lower body, but please don’t mind. I will do my best to serve you
as . Please… please play with me as you always have.” By the end,
Harukawa’s voice was hoarse and trembling.

Nagano asked, "Before we begin this week's topic on homosexuality, we need to finish the assignment from last lesson.
Whose turn is it after the last flute lesson?"

"It's me, but the teacher is here, is that okay?" a student replied.

"The teacher wants your grades to improve, Mr. Matsushita, right?"

Keiko nodded helplessly.

"It's a little embarrassing in front of the teacher, but..." As she spoke, she pulled down her trousers and
sat naked on the floor of the teacher's platform.

"Go on, let the teacher know that besides having good grades, you can also play the flute." Nagano pulled Harukawa to
the ground and untied his ropes.

Harukawa obediently crawled to the classmate who had taken off his trousers, used his long, thin hands to pull
down the foreskin of the penis in front of him, exposing the glans, and sat down on the classmate's penis, sucking it.

"Oh? Even your dick gets hard in front of a beautiful teacher." Seeing Keiko ignore him, the others
became , as usual, some playing with Harukawa's penis.

"Hey, yeah, her nipples are getting hard too." Someone else grabbed Harukawa's breasts from behind and played with them.

"Don't just enjoy it, use your mouth properly." The person who put his penis in Harukawa's mouth held Harukawa
's head down, controlling the up-and-down motion.

Keiko could only sit quietly to the side.

"We have our rules. The person with the best score in the bi-weekly math test gets to
play with the pet. Yokota-sensei's method is really good." Kuroda described the situation during extracurricular study.

"What? Yokota-sensei knows about this too!" Keiko exclaimed.

"He invented this method that requires everyone to work hard, which is why our math is among the best in the school
," Kuroda said, a hint of pride in his voice.

Keiko thought to herself: (This isn't something an educator should do; I must tell the principal…)

“Mmm…so good…” Just as Keiko was secretly planning, the boy who had inserted his penis into Harukawa’s
mouth pressed Harukawa’s head down, thrusting his buttocks, which were sitting on the ground, back and forth in his mouth.
Harukawa, who had provided oral sex before, still frowned, preparing to welcome the arrival of the vile creature.

“I want to…shoot…” He had originally intended to insert the penis to the back of his mouth before ejaculating, but during the thrusting, he couldn’t resist
the pleasure, and just as the glans was pulled to his lips, he exploded. Semen shot into his mouth and face, and
Harukawa, who had tasted semen before, hurriedly wiped the semen off his face in front of Keiko.

**************************************************************************

Nagano: “Okay, the assignment from last lesson is finished. Now let’s begin the topic of homosexuality.”

Nagano continued: “Love between men and women is innate… Homosexuality refers to
love . Some people are born attracted to the same sex, while others change later in life… And among them, there exists
another exception: homosexuality. The best example is Harukawa. He started as Mr. Matsushita’s pet, but now
he’s our toy, enjoying being abused by us…”

“To understand how homosexuals make love, we’ll use a pet’s body as a teaching material. Harukawa, lie down
and raise your buttocks.”

“This…” Although Harukawa had already experienced all forms of sexual humiliation, Keiko’s presence made him
hesitate for a moment…

"Damn it! What are you standing there for?" Nagano punched the frail Harukawa in the stomach. Harukawa
curled up on the ground, clutching his aching belly, enduring the pain. He knelt down, raised his buttocks, and covered his face with his hands. The physical wounds were nothing compared to the emotional trauma.

"When men and women have sex, men can insert into a woman's mouth, vagina, or even anus to achieve pleasure. But
between men, besides oral sex, the only other way is through the anus..." Nagano pointed at Harukawa's anus, then took out
a bottle of lotion and applied it to the anus

... "Ah!... What are you doing?" The coolness from his rear sent a chill down Harukawa's spine, and he twisted his buttocks...
Nagano used his strong body to press Harukawa down, rendering him immobile.

“Because the anus doesn’t secrete saliva or vaginal fluid like the mouth or vulva, you must use
lubricant …”

“Only Kiguchi got an A in the math test two days ago, so as usual, Kiguchi can participate in this
assignment.” Kuroda handed Kiguchi lubricant.

“Apply some to your glans first; it will make insertion easier,” Kuroda instructed.

“Yes.” Kiguchi applied the lubricant to his glans.

“No! Please spare me, not in front of the teacher…” Harukawa begged.

“Pets don’t have a choice. If you don’t comply obediently, the students who got B grades
will teach you a lesson!”

“You can’t do this! Haven’t you toyed with Harukawa enough?” Keiko finally couldn’t hold back any longer,
angrily telling Kiguchi to stop his attempt to insert his penis.

The boys, seeing that Keiko hadn't objected to the group's teasing of Harukawa, assumed she was
in cahoots with the math teacher, Yokota, and tacitly approved of the activity. The core members of the "Kuroshi-kai" were at a loss, whispering amongst themselves.

After all, Keiko was a teacher; if she dealt with it strictly, even if they weren't
imprisoned due to their young age, they would certainly be sent to a juvenile detention center. Thinking this, they became even more worried,
glancing . If they couldn't think of a solution, they would have to kneel down and beg for mercy.

Kurota: "I promised not to make things difficult for you today. Please sit back and watch. If you break
the rules, I don't have to keep my promise either. Please think carefully, teacher." "

...But...this isn't extracurricular activity; it's just teasing Harukawa!" Although she knew further argument might
have negative consequences, Keiko still resisted for Harukawa's sake.

"Teacher, besides what's in the books, there's so much more we need to learn. That's why we're doing self-study
outside . We're learning things that mainstream education doesn't teach."

"Don't try to justify yourself! This is a classroom. Who would be studying such perverse things here?" "

Oh? Is the teacher dissatisfied with the self-study topics we've chosen? If so, then using
the textbook for English class shouldn't be a problem, right? Alright, since it's Mr. Matsushita's suggestion, let's change today's topic.

Nagano, distribute the textbooks the teacher wrote."

"What... textbooks?" What kind of textbooks could they be? Keiko had always used textbooks in class and
couldn't recall ever writing any teaching materials. But the devil's intentions were unfathomable to Keiko. The more she saw Nagano
passing around sheets of blank paper, the more uneasy she became.

"No way!"

"I never would have imagined this!"

The people holding the flyers started arguing after seeing what was written on the paper.

"I forgot to give one to the teacher, Mr. Matsushita, please take a look." Kuroda handed Keiko a "teaching material."

"This is...no way..." Upon seeing the contents of the paper, Keiko realized the seriousness of the situation.

Kuroda: "Have you forgotten? This is the pledge that your teacher signed that day. Everyone, due to Mr. Matsushita's
request, we have decided to change our self-study assignment to Chinese translation, and Mr. Matsushita will naturally be our instructor.

Teacher, we will now read aloud sentence by sentence as written on the paper, and please also teach us how to translate it into English." "

No...please...I beg you..." Keiko's plea was weak; this was her
last . Keiko's chaotic heart had no choice but to await her death sentence.

Kuroda: “Teacher, get ready. I’ll read first. I am the lewd female teacher, Matsushita Keiko.
I treated Harukawa like a pet when I was his tutor.”

Nagano continued: “Actually, I also enjoy being played with and raped by my students…” Imai added: “
Because I am a true exhibitionist and masochist…”

After the members of the *Kuroshikai* read the oath, Keiko could only cover her ears with her hands, her face burning with shame, her legs
becoming unsteady, and she could barely stand. The other students, stirred by Kuroda and the oath, eagerly continued
reading the rest:

“Please play with this shameless female teacher to your heart’s content…”

“Please insert your penis into me…”

“It doesn’t matter if you fill my mouth with semen…”

“Because I am the most lewd woman who loves to eat semen…”

"If I disobey your orders, I am willing to accept severe punishment."

"Wow...that's great..." After the entire text was read aloud, the students cheered uncontrollably,
jumping around in the classroom, unable to contain their joy.

"No...I didn't..." Keiko muttered to herself, unaware of the beastly
change in everyone's eyes. The boys stared excitedly at Keiko, having already erased her identity as a teacher from their minds.

"I never imagined that the teacher had already treated Chunchuan like a pet..."

"It's like a dream, the beautiful Yingzheng is our pet..."

One after another, the little perverts, now disguised as humans, gradually lost control.

A boy said, "Instead of translating English, why not use Pet Teacher to teach another anatomy lesson? Using Chunchuan
as the teaching material before was too superficial and not realistic enough."

"Okay!"

"Great!"

Kuroda said, "Hmm...that's a good suggestion. Since everyone is so enthusiastic, please use a beautiful
body ."

"What did you say? I absolutely refuse!" Keiko angrily refused.

"Do you have a choice? You don't acknowledge the previous oath? Then I'll just have to hold another
welcome have you sign a new one. But this time the number of people is several times greater, I'm afraid you won't be able to
handle it..." Kuroda finished speaking, his sinister gaze lingering on Keiko.

"So a welcome party has already been held?"

"That means the teacher isn't a virgin anymore..."

"She really is a woman who would give up her body..."

Keiko sensed the changes in everyone, as if she were surrounded by hungry beasts, as if she could smell the scent of death.

Nagano: "I think the teacher has considered his current situation. How about this, if you're willing to be naked,
Harukawa can go back immediately. Isn't that a good deal?"

Kuroda: "Let them see. Most of these people have never seen a real woman naked before.
Anyway, the teacher is an exhibitionist, so taking off his clothes will only benefit one family and two families..."

Keiko: "I'm not an exhibitionist... how could I..."

Kuroda: "You're unwilling to sacrifice for Harukawa? How heartless! After all, he was your pet before
. Harukawa, do you hear me? It's the teacher who refuses to save you."

"The teacher firmly refuses. There's no other way. If you can't bear it, then don't hold back. Whether it's an A or B, or
any grade, I'll make an exception today and let you vent your frustrations on Harukawa."

"Fine, we can't hold back, Harukawa is fine too." One by one, the impatient little devils, as if waiting for the gates of hell to open, swarmed around
Harukawa's body.

Surrounded by a horde of beasts, with no hope of survival, Harukawa could only instinctively cry out, "Matsushita-sensei,
save me..."

Before the words even finished, a penis was shoved into his mouth. Almost simultaneously, someone else
inserted ; those who couldn't get a head start grabbed Harukawa's hand to masturbate themselves. Amidst the flying sand and stones, the dense crowd had already
engulfed Harukawa, and the lewd classroom once again resembled a scene from hell.

"No! I promise!" Keiko felt
a sense of mission . Having always treated Harukawa like a younger brother, she felt she had to stand up for him in his time of need. Keiko's
momentary compassion was pushing her further into the abyss of evil.

"The teacher has something to say, please be quiet!" Kuroda gestured for Nagano and the others to disperse the crowd.
Chunchuan , curled up on the ground, was covered in bruises from the beast's attack, his lifeless expression as if he had just been
to hell.

"Teacher, you need to be clear about what you want to say. If they go berserk again, I can't guarantee I can
suppress them again."

Seeing Chunchuan's state, Keiko's determination to rescue him grew even stronger: "Just a look is
enough ... Let Chunchuan go first, and I'll agree to show you my naked body..." Keiko compromised, and the suppressed
emotions erupted in cheers again, the atmosphere joyful yet tinged with melancholy.

"Chunchuan, we don't need you today. You can go back first, or stay and watch the teacher's performance."

As if he had experienced life and death, Chunchuan didn't even glance at Keiko, snatched his clothes back, and strode out of the classroom.

"I'm sorry, teacher..." Harukawa walked half-naked down the long corridor, inwardly blaming himself for his
cowardice , but his body, devoid of emotion, desperately wanted to escape the clutches of these beasts.

"Hey, line up according to your grades..."

"Teacher, hurry up and take your clothes off, we can't wait..."

"This is the front row, don't push..."

Keiko stood on the eight-inch-high platform, unable to believe that those surrounding it were her students;
a bunch of perverts would be a more accurate description. Although she had already exposed herself in this classroom this morning, everyone had remained seated
, and had only been peeking from afar. Now, she was about to be
completely naked in front of boys only five feet away, and cold sweat trickled down her legs beneath her miniskirt.

"Thump...thump...thump..." Heavy, rhythmic music filled the classroom.

"With music, I'm sure you can perform the striptease even better, teacher." Kuroda pressed the button on the loudspeaker
and walked over to Keiko to monitor her.

"Wha...what striptease? Isn't it just about taking your clothes off?"

"Teacher, you're dreaming! Do you think it's that simple? I'm doing this for your own good. If it's not like this,
the audience won't be satisfied. They might accidentally go crazy and rape you. Remember what happened in Harukawa
? If you don't want the same thing to happen, think about how to make all sorts of lewd gestures during the striptease,
making them unable to resist ejaculating in the audience. That might be your only chance!"

Judging from the lustful looks in the boys' eyes, Kuroda's words might actually be true. Keiko was also
half-believing, wondering what to do.

"I...I don't know how." Unable to think of a solution, Keiko began to panic.

"What a clumsy teacher! Let me teach you. First, stand in the center!" Kuroda patted Keiko's bottom. Keiko

didn't know how to do a striptease either, only thinking she could just take off each piece one by one. She gently unbuckled her belt
, clumsily pulled at the hem of her skirt, and slowly, carefully, pulled the miniskirt down, but then immediately
stopped, covering her crotch with her hands.

Kuroda shook his head. "Sigh, you really are pathetically clumsy. You have to twist your waist to the music while taking it off!
You can't Haven't you ever seen a striptease?"

"Of course not... and you're a minor, you couldn't possibly go to a place like that to watch
striptease ..."

"...Ouch!" Before she could finish, a sudden, sharp pain shot through her buttocks,
revealing a deep, bright red bruise on her snow-white bottom.

Nagano flicked the vine in his hand, sternly saying, "How dare you, a pet, contradict the chairman?
You still don't understand your place, showing your immature mind... But being a pet isn't important,
as long as your lewd body is fully mature." "

Nagano-kun, I'll be obedient, please don't hit me..." The cruel punishment left Keiko speechless
, pleading for mercy. This was wise; since emotional damage was unavoidable, why suffer physical
pain as well?

"Fine, since you admit your mistake, hurry up and twist your waist!" Nagano flicked the vine again.

“I’ll show you the steps one by one now, remember them well. First…”

Under Kuroda’s guidance, Keiko followed along with each movement. She swayed her hips from side to side, while her upper body
swayed in the opposite direction, and her head swayed to the rhythm of the music. Although she had never studied dance, her graceful body
made any movement beautiful.

Keiko shrugged, pulled open her shirt to both sides, and her ample breasts, even without a bra,
bounced firmly out, looking very confident. Before the movement was finished, her upper body made an even bigger sway, which, of course, was also
according to Kuroda’s instructions. Each time, her breasts danced from side to side in different shapes, and
the two nipples bouncing wildly were dazzling to behold.

"Okay, Keiko, but you have to wiggle your hips too..."

"Even prettier than the nude women in magazines..."

The merciless whistles and cheers echoed in the closed classroom. The students' frenzied insults against their teacher felt no
shame; the scene resembled a brothel. Keiko was terrified by this loss of humanity,
and hesitated, stopping when she was down to her last piece of clothing, her underwear. "Don't be so slow! Have you forgotten what Chairman Kuroda instructed?" Nagano's vines whipped

in the air , making a shrill sound. The past two weeks had taught Keiko that the devil's orders could not be disobeyed. She pessimistically acknowledged her fate , bent forward slightly, and was about to remove her underwear. This time, she would truly lose her teaching position. Keiko's shame made her movements slow, but this only tightened the students' grip on her emotions . At this tense moment, the students held their breath, for her vulva was about to be completely exposed . The powerful music faded, the air stilled, all senses focused on Keiko, watching her every move. As the thin fabric of her panties was pulled down past her buttocks, the crowd's uncontrolled breathing quickened, and they all crouched down, gazing upwards at the soon-to-be-revealed secret. The heavy breathing of the group caused Keiko to pause for a moment: (There was no turning back …) After confirming her fate once more, she pulled her thin panties to the ground. (I…I am no longer a teacher …) Tears welled in her eyes, reason vanished, and her trembling hands, as Kuroda had instructed, were raised and placed behind her neck, making her already firm breasts even more prominent. Against the dark blackboard, her snow-white flesh appeared even more beautiful. At this point, only one action remained for Kuroda. (Only the last one...) Keiko spread her long, beautiful legs wide, wider than her shoulders. The room was eerily silent. Keiko stood motionless on the platform, displaying her body in the most revealing way, like a statue more beautiful than Venus, captivating all who beheld her. Her open vulva seemed to evaporate sweat, radiating a mesmerizing heat. The flesh they had dreamed of or imagined was now before their eyes. The audience below were all parched, swallowing hard, frozen in afraid to move even a small movement would shatter the soap bubble of their fantasy. Even the onlookers felt the intense heat, making the source of the heat even more unbearable. Keiko was drenched in sweat; this secretion, meant to cool her down, now seemed to spread the heat even faster . (Ah... is everyone watching? Twenty people are watching...) Keiko's body seemed to have a memory of the pleasure of humiliation; under the students' insults, she naturally responded, beginning to secrete fluids. ( Don't ... let it leak out...) Her body wouldn't obey her commands, and glistening fluid gradually leaked from her labia. "You've done a pretty good job, but you can't just stand there. You have to dance a lewd, hip-twisting dance to the music." Nagano lightly tapped Keiko's buttocks with a rattan cane. At first, there were subtle swaying movements, which gradually increased in intensity with the powerful beat of the music. Using her head and the space between her legs as an axis, Keiko's buttocks rotated and twisted vigorously along this axis. This dispersed the force that was meant to concentrate and tighten her vaginal muscles, allowing the fluid to flow freely, spraying it onto the ground with each forward twist of her hips. As darkness fell, Keiko's naked body shone with a seductive glow. Her buttocks swayed incessantly, and her juices flowed freely ... The classroom of Class 5, Grade 3 at Eisei Academy was devoid of any semblance of humanity... "The previous striptease was just a prelude. Now, the enthusiastic teacher Matsushita is using her own body as teaching material to provide us with a lesson in female anatomy..." After Kuroda's speech, the students applauded and sat down around the eight-inch-high teak platform. After the spectacular striptease, everyone began to get used to Keiko's naked body, and their expressions, no longer tense, became calm. After Keiko's energetic performance of the butt-swaying dance, Kuroda announced that the second lesson would begin immediately. With her wrists bound behind her waist, she dragged her tired body, soaked in sweat, onto the cold platform. The hot sweat and vaginal fluid she had just exhaled were still on her back . Her chest heaved from the intense exercise, her breasts maintaining a firm shape despite gravity. "We can't let our teacher down. Now you must pay close attention and learn to understand the female anatomy." Kuroda gestured on Keiko's body with his teaching stick, finally pointing to her breasts: "Let's start with the breasts. Generally speaking, the breasts are the second most important erogenous zone for women, after the genitals. Why are they larger than men's? Besides breastfeeding after childbirth, they are also the easiest to attract men's attention and increase their libido ..." Kuroda circled the stick on her breasts, speaking in a lecture-like tone, stopping when the tip of the stick reached her nipple. "Look closely, these are nipples, just as sensitive as the clitoris. Because she hasn't given birth, they are pink, but they will turn black after childbirth." Kuroda teased Keiko's nipples with the tip of the stick.

At this moment, a boy raised his hand to ask a question. Kuroda: "Takeshita-kun, please ask your question."

Takeshita: "Senpai, why are the teacher's nipples more erect than usual?"

Kuroda: "Oh, you're very observant. As I said before, nipples are very important erogenous zones. They normally
only become erect when stimulated, but Matsushita-sensei is an exhibitionist. Exposing her body in front of people makes her feel sexy, so
her nipples naturally become erect..."

Keiko ignored the verbal insults. Compared to the humiliation she had suffered, this was nothing, and it no longer
embarrassed .

(Hmph, let's see how you hold back next.) Kuroda quickly realized this: "Beautiful breasts are
a woman's pride, so it's common to see women with large breasts wearing revealing or sexy clothes to show off.

But conversely, the genitals are a shameful part, so they are usually kept hidden. However, there are exceptions,
namely exhibitionists, who get pleasure from exposing their genitals. Now, we're going to learn about the structure of the female
genitals , which will also prove once again that I'm an exhibitionist. Nagano, Imai, spread my legs
!" "

No, no!" Just as Kuroda said, the genitals are a shameful part for women, and Keiko reflexively
resisted, squeezing her legs together.

Kuroda chuckled at Keiko's resistance: "By the way, let me talk about psychology. Women's psychology is very complex,
so don't be fooled by their words or actions. Because they feel embarrassed to directly say what they need, women
like to say the opposite to provoke a man's greater desire to conquer... Just like Ms. Matsushita now,
on the surface she's resisting with her legs tightly closed, but deep down she wants us to spread her legs even wider!" No matter

how hard Keiko tried, she couldn't resist the boys. Imai and Nagano each grabbed one of Keiko's legs and pulled them apart...
Her beautiful legs, which had been tightly closed like a clam shell, were now wide open, her vulva shining like a pearl. Kuroda had hit the nail on the head;
the boys had felt an even greater desire during Keiko's resistance, so seeing her plump vulva now gave them even greater
satisfaction. Keiko's lying position best showcased the three-dimensionality of her vulva; her pubic bone was slightly protruding, and beneath the wet, curly pubic hair were two
labia just moistened with vaginal fluid, the two pink, tender petals as delicate as peaches.

“Please, don’t look…” A sense of shame welled up within Keiko, fueled by a deep-seated rationality.

“What the teacher really meant was for us to look more closely,” Kuroda twisted Keiko’s words again.

“No, I really beg you not to look anymore…”

At this point, the crowd no longer cared about Keiko’s true meaning; her pleas only fueled
their aggression. They relentlessly discussed the shape, color, and subtle features of her vulva, their only desire being to
satisfy their bestial desire to humiliate their teacher.

Over the past two weeks, Keiko had experienced pleasure through humiliation countless times. Her mind had subconsciously
equated shame with orgasm, and her body had become accustomed to responding with excitement under such circumstances. Now, in
front of more than twenty students, she was displaying her still-erect genitals, feeling utterly humiliated, and her lower body was
reacting inappropriately...

(Am I going to... ejaculate again?) Keiko noticed the urge to urinate returning to her vagina. From her extensive
experience , she knew what this meant. (No...) A sliver of rationality tried to
fight against her physical sensations, trying her best to tighten the vaginal walls, not wanting to expose her shameful state again. The battle between mind and body was reaching its climax.
Her labia trembled, opening and closing in the struggle between the two sides, and the clitoris, brimming with desire, was faintly visible through the cleft. Her honest
body had tasted the sweetness of orgasm many times before, and now, regardless of her mental resistance, she wanted to experience the pleasurable
sensations she had come to love. The secreted fluids were beyond what her vagina could handle, and her strength to hold back was finally exhausted.

"Ah...it's over!" Her vaginal fluids had breached her defenses, wetting her already dried vulva again. The flow was
so profuse that the teakwood altar was soaked, turning a deeper color. Kuroda: "Everyone, please look carefully. When a woman is aroused, she secretes lubricating fluid

to facilitate intercourse . Ordinary women only secrete this fluid when their erogenous zones are stimulated by objects, but for someone like Matsushita-sensei to get this wet just from being seen is the mark of a serious exhibitionist..." "Spare me...please stop insulting me..." "Oh, are you being sarcastic again? Does anyone understand the teacher's true intentions?" "I know!" "I know too..." By this point, the children's reason had been completely eroded. They eagerly raised their hands, wanting to be the ones to humiliate their teacher . Kuroda: "Very well, then Takeshita will answer." Takeshita: "Does the teacher want us to humiliate her even more?" Kuroda: "All correct! Nagano, Imai..." Nagano and Imai, each holding Keiko's ankles, understood and, in unison, pulled up Keiko's ankles, bending them into an upside-down gourd shape. Her feet were pressed firmly to the ground, her calves were pressed against her ears, and her round, white buttocks were facing upwards, her vulva and anus fully exposed. "What kind of position is this? No... I don't want this..." "Shut up!" Kuroda used Nagano's rattan whip to strike Keiko's tender buttocks hard, adding another deep, long welt to her smooth skin. Unable to bear the excruciating pain, Keiko obediently submitted and quieted down. "You're all incredibly lucky to have such an exhibitionist teacher. You won't have many opportunities to see a woman's anus , so you'd better be careful. Now, teacher, please explain the physiology lesson and name the place I'm pointing to." Kuroda brandished his rattan whip in front of Keiko. "Isn't this insult enough? Please spare me..." "You don't want to talk? Then let's have a beating." Kuroda lashed out again at her large buttocks without hesitation. "Ah!... I'll be good, don't hit me." "Don't want the whip? Then you have to say the medical name and common name for this place." Kuroda pointed to Keiko's anus. "This...this is the anus, commonly known as...the anus." "I see, so this is the beautiful teacher's anus." Everyone laughed at the intellectual Keiko for using such vulgar language. Kuroda: "Teacher, what's the function of that spittoon?" "Well... you know that too..." Seeing Keiko's slight resistance, Kuroda added another bloody stain to her white buttocks. "Wow! I told you, this is where you poop..."

“What a despicable exhibitionist, won’t listen even if I don’t beat her. Perhaps an enema would
clarify the purpose of her anus.”

“No! I…I will obey, please…please, Master, don’t use an enema…” Keiko’s humiliation
began with an enema, a nightmare she never wanted to experience again.

“Good, you’re talking more and more like a pet.” Kuroda stroked the blood-red whip marks, admiring his masterpiece.

“And what is this place?” Kuroda moved the cursor to her vulva.

"This...this is the reproductive tract, commonly known as..., scientifically called the uterus..."

Kuroda: "Don't stop, keep going."

"...This...is also where a man inserts his penis during intercourse..."

**********************************************************************

It was already around six o'clock. Kuroda glanced at his watch and winked at Imai. Imai understood, and he and Nagano
released Keiko and left the classroom. Keiko, relieved, lay motionless on the floor.

"Ahem, the teacher's explanation is almost over, but optical theory isn't enough, so next up will
be a practical lesson, and the teaching material will be provided by Matsushita-sensei, who is more suitable than Harukawa."

(What kind of practical lesson will it be again?) Keiko suddenly had a bad feeling.

"Ms. Matsushita explained the uses of the vagina before. Horiguchi and Tomita, you both
got , so you'll get to try out my vagina today." Kuroda casually announced.

"Wow! No way!" "

Damn it! If I'd known earlier, I would have studied harder."

The announcement sent the boys into a frenzy of excitement, while Horiguchi and Tomita
were . Meanwhile, Keiko, feeling like she'd fallen into an ice cave, was also chilled to the bone by the news of her bad luck.

"No... I absolutely won't do it!"

"You can't refuse. Teachers have an obligation to improve students' grades. If a teacher offers their body as
a reward , students will work even harder. That's the purpose of a pet, but Harukawa can't
compare to a teacher no matter what."

"Nonsense! Teachers can't offer their bodies to students... I... I'm not a prostitute." "

...That's true. It seems Mr. Matsushita has no obligation to those who do well in math, so let's
change offering bodies to those who do well in English. Improving students' English while
satisfying sexual desires—a double win for the lecherous Mr. Matsushita."

"No, I'm not a lecherous teacher."

"Still denying it now? Imai, are you ready?" "

Alright." The two, who had returned, put the tape into the player and pressed the button.

"Please, Harukawa, in the classroom we're teacher and student, but here we're naked men and women,
and ... I'm going crazy with itching..." The player played footage of Keiko, under the influence of drugs,
begging Harukawa at the Kuroda house.

"Don't play it! Turn off the recorder!"

The cold, heartless machine ignored Keiko's pleas and continued to read out the secrets of their lewdness:

"...I, Matsushita Keiko, am a promiscuous woman... Please gang rape me... Ah... Ah... Ugh...
Ah..."

"...Teacher, does it feel good?

" "...Ugh... Yes... Hmm..."

Although Keiko had been engaging in such outrageous behavior in the classroom for two weeks, the students perceived
her as being somewhat coerced. Now, with the irrefutable evidence of her debauchery broadcast like a radio drama, the students, staring at
Matsushita Keiko before them, were even more certain of her status as a pet.

Kuroda: "Did you all know? She's usually such an elegant teacher, but this is the true face of this beautiful teacher." "Don't judge a book by its cover.

I never imagined Ms. Matsushita was such a lecher."

"I thought she was a remarkable teacher, but now that we know she's just a wanton woman, we can play with her even more
freely ."

One sentence after another, the students excitedly discussed, their lust rising even higher.

Keiko remained silent, dejected, yet sensing the increasingly strong, familiar, animalistic scent emanating from the students. Their
eyes perfectly reflected their own desires; their lewd gazes were fixed on Keiko, their eyes red-rimmed, gazing at their beautiful
prey, their noses already smelling blood. If it weren't for Kuroda's presence preventing them from acting rashly, they would have already pounced on her
to unleash their lust.

Kuroda observed that the crowd's reaction was exactly as he had predicted: "Can't hold back anymore? Fine, no intercourse,
you do whatever you like. Go! Don't be shy."

Everyone was already poised for action, and Kuroda's words unleashed a barrage of attacks. The students surged forward, twenty
hungry wolves vying for Keiko's body. The shadowy figures of the beasts blocked out the light, plunging Keiko into darkness,
unable to see the light or the future. Keiko could only feel the wet, slippery mouths and the frenzied claws covering her body.

Her breasts were gripped in two men's hands, kneaded forcefully, the flesh piling into different shapes in their palms. Her nipples
were sucked hard, her areolas bitten with teeth marks. Her lips were taken, someone shoved their tongue in and pounded them, someone
swept their tongue across her face, and her earlobes were sucked. Her neck, shoulders, abdomen, and legs were soaked in saliva. The most intense stimulation came from
her genitals. Her labia were parted with fingers, and a nimble tongue circled her clitoris. Like being surrounded by a pack of hungry beasts, Keiko deeply
felt the agony Harukawa had just experienced.

The endless sensory stimulation overwhelmed her central nervous system, leaving her only able to release vaginal
fluids .

The manipulators were ecstatic, drinking all the leaked fluids. There was only one woman, enough for a dozen or so men to play with at the same time. Those outside couldn't squeeze
in and simply watched the lewd scene while masturbating.

Ten minutes later, many had already ejaculated…

"Alright, that's enough. If you accidentally damage the teacher's body, you won't be able to play anymore." Kuroda
ordered Nagano and Imai to disperse the crowd.

Keiko's strength was as if she had been raped a dozen times. She was no longer in the boy's grasp, but her body still trembled slightly on the platform, lingering in the afterglow of
ecstasy .

"Matsushita-sensei, do you understand? Now, twenty men can gang rape you continuously. Each energetic boy
can probably do it five times. So, if you do the math… the teacher will be raped a hundred times! This is the depraved teacher…"
"Even I couldn't handle it. What do you think? How about we just let the good students play with it?"

"Uh...uh...okay, I'll listen, but...please don't do it here..." Having no better
choice, Keiko had no choice but to comply.

"It's best if you listen. Horiguchi and Tomita, then come to my house for your sex practice. But does the teacher remember what you said in
your oath ? You refused to provide your body as teaching material for sex before, so now you're being punished—
you'll masturbate in front of everyone."

"No, I promised...it should be for the good students...not here."

"You bastard! Have you forgotten to listen?" Kuroda whipped Keiko several times with a rattan cane. Her exhausted body could
no longer withstand the pain, and Keiko hurriedly begged for mercy.

"I know I was wrong, please don't hit me, I just masturbated..."

"Masturbating in front of so many people must be very interesting for an exhibitionist, but I still need to teach you the
details ..." Kuroda untied the rope from Keiko's wrists and whispered instructions in her ear.

The students then sat in an orderly fashion around the teaching platform, waiting for the show to begin.

Keiko tidied her soiled body slightly, knelt on the platform in a Japanese sitting posture, placed her hands on her knees, and
began her masturbation performance with a humble attitude, following Kuroda's instructions.

"Dear students, thank you for using me as teaching material today. To express my gratitude, and to apologize to those who couldn't participate in
the sex ... I will now perform masturbation for you. Please watch carefully as my lewd teacher
performs. "

Keiko slowly stood up, her two-centimeter-high heels barely supporting her swaying body. She first
lifted her heavy breasts with her hands, then let them fall, repeating this several times to fully
showcase . Kuroda: "

Next step."

Keiko paused, then pinched her nipple between her fingers, manipulating it until it became erect.

Kuroda: "Almost there, next step."

His hand left her breast, moved past her waist, and slid down to her lower abdomen, then rubbed between her pubic hair and pubic flesh.

"Use two fingers of your right hand to part your labia."

"Okay, then use your other hand to rub your clitoris." Keiko

followed Kuroda's instructions step by step, while the boy, sitting upright, pulled out his penis and watched Keiko
masturbate .

At first, it was unintentional, but her body seemed to have lost its ability to regulate itself; any stronger stimulation would cause
her to become aroused naturally. Her already cleaned vulva glistened with lust again, and her uncooperative vulva began to secrete fluids once more.

(Hmm… she's gradually showing the results of her training.) Kuroda observed Keiko's bodily reflexes and
began to plan deeper training methods.

(Ah...how could this be...can being forced to masturbate in front of twenty students still be sexy...?) Keiko's hand moved faster
with her physical needs, waves of pleasure washing over her, to the point where she craved a man's penis.
She probably wouldn't resist if someone tried to rape her. (I...I'm really a masochist...) To satisfy her
urgent sexual desire, Keiko used admitting her lowly status as an excuse, thus masking her pride and allowing herself
to indulge in wantonness.

Keiko prepared herself mentally, and inserted a finger into her vagina. (Ah...) She tilted her head back to
receive the moment of satisfaction, her vaginal fluids overflowing and splashing across her thighs. (Good...good...) Having experienced
the pleasure of penetration, she became addicted to this sexual beauty, withdrawing her finger and inserting it again, her vaginal fluids flowing even more freely.

This action was repeated several times, and her other hand naturally rubbed against her clitoris. (Coming...coming...)
The arrival of orgasm caused her body to tremble, her legs could no longer support her lustful body, and her knees buckled on the ground, but her hand
had not yet left her clitoris.

Her head was raised high, her waist arched like a bridge, and her vagina had been aroused to a lustful state. At this moment, Keiko inserted two fingers and
fiercely thrust them into her vagina. This was no longer an action instructed by Kuroda; it was an act of
reckless .

At this moment, the students could no longer balance their bodies and lay half-reclined, letting themselves freely stroke the penis.

(Okay...okay...it's coming again...!) The rapid thrusting of fingers pumped out Keiko's juices, spraying them
forward and breaking through the air. "Ah...ah..." Keiko was already in a frenzy, her mouth uttering
gasps of climax, unable to hold back any longer. (She clenched...so this is what clenching feels like...) Her face was contorted, appearing to be
in pain, but truly in ecstasy.

"Ah!" "Keiko screamed as her fingers were firmly inserted to the root, her buttocks thrusting upwards, reaching an unprecedented
peak of masturbation, savoring the delicious afterglow.

At the same time as Keiko's frenzy, the student also reached his climax, twenty spurts of semen erupting...

The breath of a wild beast, the stench of semen—the only sound in the classroom of Yingzheng Academy was this...

Night fell, and the abode of the demons received guests... no, pets, more like pets. After a whole day of being abused by the students,
Keiko was exhausted.

She ordered takeout from a restaurant, and then the six boys dragged Keiko into Kuroda's detached building behind the hospital.

Upon entering, Kuroda ordered Keiko to strip naked. Exposing her body was no longer difficult for Keiko; her thin clothes
and short skirt were easily removed.

"Huh? What is this?" Nagano slipped a leather dog leash around Keiko's neck from behind: "This is
a gift for you, and also a way for your pet to recognize you. Wear it every time you come; you'll get used to it eventually."

"Come on, let's eat." Imai placed a bowl of cold rice on the ground, then shoved Keiko down:
"You have to eat like a dog, not with your hands."

Keiko stared at the dog food; even smelling it made her uncomfortable, let alone eating it.

"You naughty pet, so disobedient! You're awful!" Imai mercilessly whipped Keiko's back with the leather belt.

"Waaah! Please don't hit me, I'll eat!" "Keiko succumbed to the violence, crawling on her hands and feet,
and swallowed a mouthful of rice from the bowl. She closed her eyes, tears streaming down her face. Suppressing her anger, she
ate the rice mixed with her tears. A bitter taste, then

a deep sorrow, welled up inside her. The students, watching Keiko, felt their sadistic desires growing ever stronger.

After the meal, the boys half-dragged, half-pushed Keiko up to the dormitory on the second floor.

"Get on the bed!" Pushing Keiko to the bedside, the boys, impatient, began hastily tearing
off their school uniforms.

"Please, I'm a teacher! How can a group of students rape a teacher… If this gets out
, you'll all be punished! Please stop immediately!" Keiko pleaded, kneeling."

The plea was laced with a threat, and the two inexperienced students, Horiguchi and Tomita, began to worry.

"No one will know, because students are also beneficiaries; they would never say a word.
Unless it's the teacher himself. But don't forget I have photos of the teacher's wanton behavior and countless witnesses who can testify against him. That
might not be enough to convict me. Besides, if you dare to leak even a word, I have ways to make things even worse for you.
You should think about your mother at home."

"Yes, don't worry. Remember the president's psychological guidance on women today? What the teacher said and what she thought
were exactly the opposite. When she said no, she meant she wanted to go all out, understand?" Nagano encouraged the two timid students,
putting his arm around their shoulders.

"President Kuroda, should we use this again this time?" Ihara brought out the aphrodisiac
ointment .

“No, this bitch still won’t listen. Tonight, we’ll force her! We can also use rape to boost
the confidence of the coward.” Imai and Ihara grabbed Keiko’s arm and forced her onto the bed.

“Last time, she wriggled her ass and wanted me to do it, but it always felt like something was missing—the feeling of torturing a teacher. But this time,
it’s real rape, it’ll be much more exciting.”

“Teacher, you should struggle a bit. That way, it’ll be more fun for us to gang rape you.”

“If you want us to rape you more fiercely, scream and make a fuss.”

Keiko became a sacrifice to the lecherous demons, her wrists and ankles tied to the four corners of the bed with ropes. A
sacrifice was thus displayed on the altar.

"No, please spare me..." Although she had tried countless times to expose herself and
ejaculate , tonight's gang rape was different. Furthermore, without any aphrodisiacs, her clear
-headedness dictated resistance. Keiko's skin, bound by the rope, was abraded from her fierce struggles, but
all her movements were futile, only intensifying the students' aggression.

Meanwhile, the two boys who had hesitated earlier, seeing a beautiful female body swaying on the bed, forgot all their previous
worries Never mind, let's do it first...

Kuroda: "Horiguchi, Tomita, you can do the teacher now."

"Can we?"

"I... I want to go first..." The eager Horiguchi climbed onto Keiko first.

"Teacher's breasts are so smooth!" The small, weak Horiguchi couldn't stand out from the crowd in the classroom
, only able to reach out and touch Keiko through the gaps in the crowd. Now, with two complete breasts at his mercy, Horiguchi was so nervous
he didn't know where to begin. Gradually, he remembered scenes from pornographic films and began to imitate them on Keiko's
body. Horiguchi's hands kneaded Keiko's breasts like milking a cow, licking
the nipples that swayed before his eyes with his tongue, and soon he became erect. With each stimulation, Keiko's upper body trembled. The inexperienced Horiguchi
could no longer resist. He guided his penis to Keiko's vulva, and
the boy, unaware that he shouldn't wait for the woman to secrete vaginal fluid before intercourse, thrust his penis all the way in. Because it was an still-developing penis, the small
shaft barely managed to penetrate the dry vagina, but it already caused Keiko to scream in agony.

Keiko felt as if her vagina was being torn apart; this was the agony of being raped. If she hadn't already been deflowered,
this excruciating pain would have made her faint.

The glans penis was slightly sore from the dry friction, but seeing Keiko's painful cries gave him a great sense
of conquest . After settling down, the glans felt the warm, tight walls of her vagina gripping it. How could a virgin withstand this
double pleasure? He felt a dizziness, and Horiguchi ejaculated.

Keiko felt that Horiguchi's semen was plentiful, and it lasted for several seconds before stopping. Having released his pent-up desire, Horiguchi slumped against Keiko's
chest, panting.

"Useless, let me try." Tomita, caught off guard, pushed Horiguchi away from Keiko. He
was already impatiently waiting, and without any foreplay, he wanted to penetrate her long-desired vagina. He rubbed
his glans her labia to probe the entrance, but unexpectedly, his eager anticipation and the pleasure of rubbing against her vulva caused him
to ejaculate, his semen spraying across Keiko's lower abdomen.

"You're so fast too? Don't be discouraged, you can try again after you recover. Now watch us demonstrate
."

"Hmph, you didn't pay attention in the anatomy class earlier. To have sex with a woman, dry penetration won't work; the most important thing is
to make her produce vaginal fluid first. The best way is to stimulate her erogenous zones, such as her ears, neck, abdomen, legs,
breasts, and genitals." Imai finished speaking and began to rub and lick Keiko's large breasts.

"No, don't do this..." The itching on her breasts made Keiko writhe.

"See, because she's a masochist, she gets aroused with just one lick." Imai sucked on Keiko's nipple,
making a sucking sound, while Ihara also took over the other breast.

Keiko began to enter a state of confusion, her breasts were rubbed until they were soft and swollen, the nipples felt sweet when licked, and
sour and bitter when bitten. Her body writhed on the bed, her limbs were stretched tightly, and fluid seeped from her secret place between her legs, wetting
the bed.

"Hmm, it's already this wet, it's ready to use." Nagano lifted Keiko's waist, raising her vulva to the right
height, and with a "slap!" he thrust his penis, already aimed at the entrance, all the way in.

"Oh...oh..." The long and strong penis was incomparable to Horiguchi and Tomita, hitting the very core in one go.

This was no longer the influence of drugs; it was a truly conscious experience of intercourse. Keiko could clearly feel the hot
object filling her vagina, the glans burning hot, as if it would evaporate all the moisture.

"So tight already? It's not long, it'll be even more pleasurable." Nagano showed no mercy to Keiko's vulva, his
powerful thrusting drawing out her juices, splashing them all over their lower bodies,
adding .

Before, she could use the excuse of being driven by aphrodisiacs, but now it was a genuine physical reaction. Although Keiko was
extremely unwilling, she couldn't resist the waves of sensual pleasure, her whole body under his control, shaking her head and screaming with ecstasy.

"Teacher's moans sound just like a porn star..."

"Yes, just as sweet, just as lewd, truly captivating..."

Under the frenzied thrusting, Keiko's vagina went numb, the muscles tightening with each stroke, and soon she
spurted out vaginal fluid, splashing it onto his glans, experiencing the pleasure of finally releasing pent-up urine. Keiko thoroughly enjoyed it.

"Is Teacher about to cum?...Okay...I'll cum too..." Nagano inserted his penis all the way in, and
streams of hot semen filled her vagina.

He only withdrew his penis when it had softened from being sucked by her vagina. A mixture of semen and vaginal fluid flowed from her opening. Without the support of
drugs , Keiko lay limp, panting heavily.

"It's not over yet, it's my turn. Give it your all, teacher." Imai pressed Keiko down, inserting his penis into her soaking wet
vagina, simultaneously prolonging Keiko's lingering orgasm. Imai and Keiko faced each other, their noses rubbing together.
Imai loved enjoying the changes in Keiko's expressions during his pleasure. When he deliberately slowed down, she would grit her teeth and gasp, but
when he switched to a frenzied thrusting, she would cry out, her head bowed. It was so interesting and so much fun. Although Keiko knew Imai was
deliberately playing with her like this, her body obediently responded, unable to suppress it.

Seeing his teacher being manipulated, Imai felt a sense of conquest and ejaculated inside Keiko again
.

"Look how much the teacher is enjoying herself. Do you remember how many times she went to heaven?"

"She doesn't look like a woman who was deflowered just two weeks ago. Perhaps this could be called 'congenital promiscuity'

!"

After that, one after another, for two weeks, Horiguchi and Tomita had made progress, stirring dozens of
times inside her before finally ejaculating due to her still extremely sensitive vagina…

Young people have inexhaustible energy. Nagano and the others, having waited two weeks to have sex with this beauty, were naturally
not easily satisfied. The two boys, experiencing women for the first time, were even more unsatisfied, their penises hard, waiting for the next round.
However, when Kuroda raised his hand to stop, no one dared to go any further, knowing the game was over.

Keiko's body was covered in men's semen, her hair disheveled, her vulva swollen and red from being penetrated, her legs
numb , and the abrasions from the ropes binding her limbs ached with sweat. Seeing that no more men were climbing on top of her,
Keiko said, "You've humiliated me enough, haven't you? Let me go, I want to go home."

Kuroda exhaled a comfortable smoke ring: "Is Teacher satisfied? So eager to leave. But I haven't
done it !"

"If you want to do it, then do it. I'm already very tired. Hurry up and finish so I can go home." At this point,
whether it was one man or ten men, it didn't matter to Keiko; she only wanted to leave quickly.

"Teacher, do you want me to do you? Then I'll do it... Nagano, lift her legs."

Kuroda picked up the aphrodisiac ointment from the ground. Nagano had already pulled Keiko's legs back towards the headboard, her smooth buttocks
exposed. Keiko, who was no longer aware of being raped, felt a little uneasy. The others were happy to watch the next
scene sex.

"Look how swollen your genitals are, teacher. We can't use it again tonight, but it's not a big deal, because I'm
more interested in this area." Kuroda applied the aphrodisiac to Keiko's anus. The cool sensation made Keiko understand Kuroda's
evil intentions.

"No, you can't use it here..."

"A good pet should use its ass to please its master. Harukawa cries tears of joy when it's penetrated here!

Don't worry, it's fun. You'll love it after you've tried it once."

While Keiko wasn't paying attention, Kuroda inserted his entire index finger straight into her anus. With the help of the moist aphrodisiac,
this action was easy.

"It hurts!... Not here, if you want to penetrate me... just use your vagina as usual!"

Even inserting a finger caused such excruciating pain; what would it be like to insert Kuroda's large penis? This was Keiko's
biggest worry.

The walls were soaked with ointment that had seeped in from her body heat, and after several slow insertions, her fingers could now move in and out smoothly. The nimble
fingers stirred and teased inside her anus, a sensation far better than a hard penis; the rubbing, shifting left and right, was almost unbearable for Keiko
.

"Mmm...no...like this..." Keiko writhed wildly, her two buttocks
pointing skyward. Besides Kuroda's skillful fingers, the effects of the aphrodisiac were the biggest factor. Each stimulation tightened the inner walls, like
sucking on a finger.

Gradually, the tingling, itchy sensation returned, assaulting Keiko's senses once more.
A seductive blush returned to her face, her lips trembled, and with soft moans, the dignified teacher transformed into a wanton woman.

"I didn't expect this hole to know how to suck, but it doesn't seem very clean
. It'd be better to wash it with an enema."

"No... Kuroda-kun... Master, I'll agree to anything... Don't use an enema... You
can play however you like, just do it..." She seemed to refuse the enema, but in reality, she couldn't resist the drug's effects. She
didn't know how long the enema would last, so she couldn't wait and demanded to be done.

"Want it? Suck this clean first." Kuroda pulled out his filthy finger and placed it in front of Keiko.

Keiko considered it, looking at the thing covered in yellow fluid that had been swirling inside her anus, feeling somewhat nauseous.

But her physical needs were urgent; the feeling of insects biting inside her anus was overwhelming. She couldn't care less, and Keiko
opened her mouth and sucked the finger clean in one gulp.

"You did very well, I can let you go, but the teacher must ask..."

**************************************************************************

Keiko knelt down by the bed, hands on her knees, head bowed, pleading: "I will release Keiko's anus, it belongs to the master
... Keiko will crawl on the ground, raising her buttocks to welcome the master's penis... Please, master, enjoy the virginity of your anus
..." After saying this, Keiko turned around and crawled on the ground, presenting her beautiful buttocks to Kuroda.

Kuroda knelt behind Keiko, rubbing his glans against her anus.

"...Master, it hurts so much... Don't torture Keiko anymore..." Keiko seemed unbearable under Kuroda's teasing
, repeatedly thrusting her buttocks back, trying to take his penis in.

"Haha... You want it this much? Look at you, you slut, you're even more erotic than me!"

Having played with her enough, Kuroda thrust his penis inside, taking Keiko's anal virginity.

"Ouch..." More or less because of her anticipation, the initial pain of the tearing turned into pleasure,
and Keiko cried out with every thrust.

"What a secret hole that sucks in semen, it feels so good..." Kuroda pressed Keiko's waist down, making her buttocks more
upturned , making it easier to thrust. His ten fingers gripped her two snow-white buttocks tightly, ignoring Keiko's feelings, his powerful thrusts
only for his own amusement, as if he were merely playing with an inflatable doll.

"Wow!... Master... please slow down... Keiko... can't take it..." Keiko crawled on
the ground , trying to avoid the rapid ravaging of his penis, but her buttocks were immobilized under Kuroda's force.

Kuroda slightly loosened his grip, allowing Keiko to crawl forward a little. Keiko thought she had successfully dodged...
With each thrust of his penis fully inside, Keiko felt a slight sense of relief. But this was just Kuroda's lewd game; his penis continued its relentless assault
on her now-moved anus.

Keiko was startled to find the ferocious phallus still relentlessly attacking. Her upper body, exhausted, crawled forward, while Kuroda followed, kneeling beside
her , his penis relentlessly penetrating her anus. Keiko crawled like a dog, her relentless
pursuit by Kuroda creating a scene resembling a circus among the onlookers, who clapped and cheered.

"Come on, come on, teacher, crawl over here and perform..."

"Hee, little dog, come this way..."

The humiliation in her ears and the half-sexually stimulating lewd play behind her drained Keiko of her strength. When she reached Ihara's feet,
she collapsed, her body wet with vaginal fluids, leaving trails on the ground where she had crawled.

Standing there, Ihara looked at Kuroda for instructions, and Kuroda nodded in response. Ihara roughly
grabbed , and the proudly erect penis before her deepened Keiko's image of the thing wreaking havoc inside her.

Ihara: "Since the back virginity was given to the chairman, I'll use the front one."

Ihara pinched Keiko's nose shut, forcing her to breathe through her mouth. Keiko opened her mouth wide and inhaled deeply,
providing Ihara with a hole to accommodate his penis. His mouth, like a black hole,
swallowed , and Ihara immediately pushed the egg-shaped glans to the back of his throat.

"Keep your teeth in, be careful not to damage my treasure." Ihara began to sway his hips,
rubbing his glans against his wet tongue.

The penis in her eyes thrust in and out of her mouth, saliva making the ugly thing gleam with a lewd light. Behind her
was the ecstasy of swallowing and spitting, an indistinguishable itch. Before her was the merciless stabbing, an unbearable bitterness. Keiko teetered between heaven and
hell . Closing her eyes, she slowly lost the distinction, for these were also
sex organs for men, ultimately just places for men to ejaculate.

Tears streamed from the windows of her soul, staining her face; the mark of the toy was deeply imprinted on her heart…

A shooting star streaked across the sky of purgatory, a pure heart falling into the abyss.

Who knows what fate awaits Ms. Keiko… only heaven knows?
