A chaotic physiology class

"Tap tap..."
Accompanied by the pleasant sound of high heels, Ms. Xiaoyue stepped into the classroom.
The noisy classroom quieted down momentarily. Ms. Xiaoyue's appearance always caught the boys' attention,
and not only the boys, but all the girls in the class secretly observed her attire, comparing and imitating her. Today, Ms. Xiaoyue wore a moon-white cotton dress, her hair adorned with a yellow hair clip,
exuding youthful vitality. Her slender arms revealed fair skin, subtly revealing the color of jade
, crystal clear.
Even more captivating were her long, shapely legs, peeking out from under the hem of her dress. She wasn't wearing stockings, but rather
white high-heeled sandals, her five snow-white toes peeking out like five flower petals,
swaying gently with each step.
Faint blue veins were faintly visible on the tops of her feet.
Ms. Xiaoyue had only graduated a year ago, yet she taught physiology and hygiene. She was charming and exuded
a mature air; her classes were never missed.
Today's lesson was on reproductive health. The students arrived early; the girls
were there, and the boys, though many already knew the material by heart, had been eagerly anticipating it.
The lecture began, and as usual, Ms. Xiaoyue's lecture was delivered in a gentle, detailed manner. When she talked about male genital
physiology, the girls mostly listened with their heads down and blushing.
When she discussed female genitalia, the classroom was so quiet you could hear a pin drop. Ms. Xiaoyue said
, "Look at illustration eleven in the book. At the upper part of the vulva, covered by the foreskin, is the clitoris,
a sensitive area of the female genitalia. Although small, it has nerve endings similar to those in the male glans penis. When stimulated
, it erects like a penis..."
At this moment, Zhang Peng, sitting in the back row, curiously adjusted his glasses and looked up at the teacher. His deskmate, Li Xia,
immediately knew he was about to ask a question—"This bookworm,"
Li Xia muttered to herself, "How dare he ask such a question!" Sure enough, Zhang Peng asked, "Teacher Xiaoyue,
when the clitoris is erect, is it the same size as the penis? What's the difference between it and a boy's?"
Teacher Xiaoyue blushed, then calmly replied, "No, the clitoris itself is very small, and it doesn't get
very big when erect."
"Oh, how big is it then?"
"About... this big..."
Teacher Xiaoyue gestured with her hand.
"It would be great if we had a real object to compare it to. I know what a penis looks like, but I've never seen a clitoris..."
As soon as this bookworm said this, the class burst into giggles, and even some of the girls couldn't help but blush
and laugh.
"Uh, this..."
Teacher Xiaoyue hesitated, lowered her head for a moment, and as if she had made up her mind, said, "How about this, today we
can use real objects to explain it to everyone, so that everyone can better understand female physiology. However,
this goes against some social ethics and morality, so I hope everyone will treat it correctly and not tell anyone!"
As soon as she finished speaking, several quick-fingered boys immediately closed the doors and windows and drew the curtains.
The atmosphere in the classroom changed instantly, and everyone stared at Teacher Xiaoyue.
Teacher Xiaoyue bit her lip, her white teeth flashing. "I'm four or five years older than you, and
my development is a bit better. Take me as an example..."
Teacher Xiaoyue turned her back, reaching under her skirt to pull down her panties,
revealing her fair, full thighs. Several girls noticed her formally styled black lace panties.
Although she quickly crumpled them into a ball and stuffed them into her bag, she couldn't escape the notice of a few girls.
The teacher turned away, her face slightly flushed. After taking a few deep breaths, she gradually regained her composure, lifted her legs, and
laboriously sat down on the lectern, instinctively covering her crotch as she did so.
Teacher Xiaoyue spread her legs, her gaze now somewhat resolute, perhaps after an internal struggle, and said
, "Now, we will begin to explain the physiology of female external genitalia."
After saying that, she lifted her long skirt, pulling it up high to her waist. Between her two snow-white thighs, there was
a black area with not much hair, appearing as a pale black from a distance. Within the black, the pale pink labia were faintly visible.
The entire class seemed to hold their breath as the teacher, with two slender fingers, parted her labia and explained:
"These are the labia majora, with pubic hair distributed on them... These two are the labia minora, which protect the vaginal opening.
With increased sexual activity, they may darken due to pigmentation..."
Zhang Ming asked, "Teacher, your current color shouldn't have any pigmentation, right?"
Teacher Xiaoyue looked up at Zhang Ming, a fleeting blush crossing her face. "No... not that much."
"Then,"
Zhang Ming continued, "where is your hymen, Teacher?"
This time, Teacher Xiaoyue's face turned completely red. "My hymen is gone. In a bit, we can see
which female student can demonstrate..."
She then looked up at everyone, and many girls immediately lowered their heads.
"Zhang Peng, look, this is the clitoris, under the foreskin..."
"Teacher, what's that wetness on your labia? Is it urine?" The teacher's face, which had just recovered somewhat, immediately turned red again, and she said shyly
, "No, it's vaginal secretions,
which help with penile insertion. It's secreted during sexual arousal..."
"Then now..." Even Zhang Peng, a bookworm, felt that his question was inappropriate. "Teacher, you said the clitoris gets erect when aroused, what does it look like?" Teacher Xiaoyue bit her lip again, her teeth gleaming. "Okay, watch." She then began gently rubbing her clitoris with the tip of her right middle finger, while her left hand parted her vulva . Her slender fingers spun rapidly, her flesh-colored nail polish making her skin appear both white and rosy. It was clear her movements were quite skilled… "Ah—" Before she knew it, Teacher Xiaoyue's cheeks were flushed. "Zhang Peng, did you see that? Ah—Isn't my clitoris getting bigger? Ah, I'm about to climax! Ah, ah , um, I can't take it anymore, oh—" With a long moan, Teacher Xiaoyue's face contorted, her beauty scrunched up, her neck arched as she stared intently at her lower abdomen, then she collapsed onto the lectern. The classroom was quiet, save for the heavy breathing that rose and fell.

A minute later, Teacher Xiaoyue slowly sat up, glancing shyly at the students.
"Did you all see that? I just demonstrated the structure of female genitalia."
She started putting on her underwear. Zhang Peng, sharp-eyed, exclaimed, "Teacher, your fluids are on the table..."
The teacher blushed. "Well, that's a normal physiological reaction. Now, who will demonstrate male
genitalia ? Liu Feng, would you like to?"
Teacher Xiaoyue had already noticed Liu Feng sitting there, his erect penis pressing high against his crotch.
Liu Feng grunted, blushing as he stood up, his back noticeably hunched. Teacher Xiaoyue couldn't help but
smile , take off your pants and
come over here."
Liu Feng pulled down his pants and underwear, revealing a long, bright red penis that swayed back and
forth. Several girls glanced at him, blushing and lowering their heads.
Liu Feng, wearing a white shirt and naked from the waist down, walked to the podium, facing the class.
Teacher Xiaoyue stretched out her slender hand and lifted Liu Feng's penis. Actually, it didn't need to be lifted; Liu Feng's penis
was thick and hard, standing straight up, trembling slightly in Teacher Xiaoyue's hand. "Look, everyone, this is
the male external genitalia... Ladies, please lift it up, there's nothing to be embarrassed about, we're
studying science here... Right, that's good. Look, everyone, this is the male external genitalia. This is the penis
, and the swollen part at the front is the glans, which has many nerve endings and is very sensitive. This is the foreskin, which
covers and protects the penis. After a man matures, the foreskin retracts, exposing the glans. Oh, Liu Feng's foreskin is
a bit too long... See, everyone, do you see this? This is the glans. Because it's been covered by the foreskin for many years, its color is pink
. If there's a lot of sexual activity, the skin of the glans will darken..."
"Teacher,"
Liu Feng hesitated before speaking, "Is my penis... is it... very short?"
"Hehe,"
Teacher Xiaoyue laughed. "Most boys are very concerned about this issue. Actually, the size of a man's penis
is not much different after erection, and the length does not affect the quality of sex life, so everyone should not worry too much about their
length. Besides, your length is already quite good, and it is slightly upturned after erection, making it easier for women
to reach orgasm..."
At this point, Teacher Xiaoyue paused, blushed, and glanced at everyone. Everyone's attention
seemed to be on Liu Feng's genitals. Teacher Xiaoyue quickly continued, "This is the scrotum, inside which are two testicles,
the place where sperm is produced. Unlike women, men's urine and semen come out from the urethra..."
Everyone listened very attentively as Teacher Xiaoyue explained in detail the physiology of men.
"Next, please have Liu Feng demonstrate the process of male ejaculation. Everyone should observe carefully..."
"Ah, this, what, I can't..."
Liu Feng hurriedly said. Teacher Xiaoyue said, "This is a very serious matter. Don't have any other concerns."
Liu Feng had no choice but to pick up his limp little brother with his hand and try to move it a couple of times, but his little brother was still limp
and unresponsive. Liu Feng looked up at Teacher Xiaoyue with a bitter face, "I can't, teacher, I..."
Teacher Xiaoyue covered her mouth and laughed, "Hehe, it seems that someone needs to help you. Here's what we'll do."
The teacher looked around and said, "Wang Fang, you come up here!"
Wang Fang was Liu Feng's deskmate. She was usually very talkative and a crazy girl, but she was also very beautiful
, even a little seductive. The boys all liked to joke with her.
Wang Fang pouted and said, "No! Why me? I won't touch his thing!"
Teacher Xiaoyue smiled and said, "If you won't touch it, then, when I was demonstrating for everyone just now, who put their hand
inside Liu Feng's pants?" The students in the classroom laughed, and Wang Fang
's face turned even redder. She stood up awkwardly. Today she was wearing a very short skirt, and from behind, her two strong, fair legs were particularly eye-catching. For some reason , Wang Fang unconsciously pressed her skirt as she stood up, as if afraid that everyone would see something. Wang Fang walked to the podium, picked up Liu Feng's penis, and reluctantly started to stroke it. It was clear that this wasn't the first time she had stroked a man's penis, but Liu Feng's penis still didn't get any action, making Wang Fang roll her eyes and mutter something unintelligible. At this moment, Liu Feng slipped his hand inside Wang Fang's collar, grasped her breast, and began kneading it roughly. Wang Fang twisted her body, but was helpless, letting him shamelessly pinch her nipples. Liu Feng's penis seemed to get a little aroused, but slowly it became limp again. Teacher Xiaoyue said, "With sufficient sexual stimulation, the penis will fully erect. Currently, the penis is not receiving enough stimulation, mainly because it is not receiving enough stimulation from the cerebral cortex..." At this moment, Liu Feng's hand withdrew from Wang Fang's collar and slipped under her skirt, kneading her plump buttocks. From Liu Feng's kneading, the students could vaguely see Wang Fang's fair thighs and a corner of her buttocks. The boys stared greedily, and the girls, knowing that Wang Fang's buttocks were very full and perky, also looked on with some envy. Suddenly, Liu Feng grabbed Wang Fang's skirt by the sides and lifted it up abruptly. Before Wang Fang could react , her skirt was off, leaving her only in her underwear. At this moment, Wang Fang screamed, "What are you doing!—You're so annoying—" "Hehe, didn't the teacher say you weren't exciting enough? Besides, your panties were soaking wet just now, I even felt them…" Wang Fang blushed, spat, and pulled her panties down. The sharp-eyed boys saw that there was indeed . The girls noticed that Wang Fang's panties were the same brand as the teacher's, except the teacher's were black with lace trim, while Wang Fang's were black thongs. Wang Fang pulled her panties off and threw them at Liu Feng's head, bursting into laughter. Wang Fang was still an outgoing and decisive girl; although somewhat shy, she reverted to her usual self. Although Wang Fang was young, she was indeed very well-developed, with a patch of dark pubic hair. Liu Fengchen also took off her bra, exposing a pair of full breasts to everyone. Although Teacher Xiaoyue was several years older than her , she felt that her own breasts were much smaller in comparison, and her pink areolas were something she couldn't compare to.

The teacher blushed slightly. "Luckily, I didn't take off my bra earlier. Sigh, it's all because
I rubbed it too much when I masturbated..."
Teacher Xiaoyue thought to herself.
No one knew what the teacher was thinking, and no one cared. All eyes were on Wang Fang's voluptuous
body. Boys and girls alike were presented with a full, perfect naked body, especially since she was usually a very
open and wild girl. All the boys' penises were erect, except for Liu Feng's.
Wang Fang felt a little embarrassed by everyone's stares. As if she had made up her mind, she squatted down, grasped Liu Feng
's long, but somewhat limp penis, opened her mouth, and slowly but firmly took the glans into
her mouth , beginning to give him oral sex! Almost all the boys opened their mouths, watching in surprise. Several
naive girls covered their eyes, yet peeked out through their fingers unwillingly.
Having regained her composure, Ms. Xiaoyue said, "There are many kinds of sexual stimulation, including visual and
tactile , all of which can cause penile erection..."
Aside from the teacher's soft explanation, the only other sound in the classroom was Wang Fang performing oral sex on Liu Feng, the soft "slurping..." echoing
endlessly. Wang Fang looked up at Liu Feng, her eyes full of mockery and provocation, because Liu Feng's penis
was already at its maximum size, the egg-sized glans almost filling Wang Fang's mouth. Wang Fang would occasionally spit out the glans,
rapidly stroking his penis with her hand, then sucking on it for a while, stroking it again... Under the light, Liu Feng's glans
gleamed white... …Liu Feng had already closed his eyes, his heavy breathing gradually turning into moans. Wang Fang was squatting
on the ground, diligently performing oral sex and masturbation on him. Li Ming in the front row had noticed long ago that Wang Fang's anus was also vaguely visible
, as were two slightly visible labia minora. In the most private part, with the movement of her body, a little bit of moisture
glistened… The teacher looked up at the students, and all the students were staring at the scene of intense oral sex on the podium
. Almost half of the boys had already taken out their penises and were masturbating. Several girls also put their hands under their skirts and
silently stirred their fingers. Without exception, everyone's face was flushed.
It seems today's physiology and hygiene class went a bit too far, Teacher Xiaoyue couldn't help but think. But
it's good this way; it lets everyone understand more fully and learn how to protect themselves in today's society… "Masturbation
itself isn't harmful to the body. It should be treated correctly; don't have any mental burden. Just be
moderate and pay attention to hygiene, especially for girls…"
Teacher Xiaoyue explained. Suddenly, the remaining boys, who were still somewhat hesitant, pulled down their pants
or exposed their genitals, brazenly starting to masturbate. Several boys even
looked at their female classmates with a smug expression while masturbating.
Some girls stopped their activities between their legs, while others secretly reached for their genitals…
Everyone's attention remained focused on the ongoing "male genital demonstration."
Liu Feng suddenly grabbed Wang Fang's head, stopping her thrusting. Teacher Xiaoyue thought he had ejaculated and
was about to explain when Liu Feng picked up Wang Fang, placed her on the desk, spread her legs
, and was about to penetrate her.
Teacher Xiaoyue hurriedly said, "No! Every woman's virginity should be given to her husband; that's perfect
sex. Wang Fang, she..."
"Wang Fang's virginity was already..."
Liu Feng rudely interrupted the teacher, but Wang Fang screamed, "Shut up! Don't say that—"
As she spoke, she hooked her legs around Liu Feng's buttocks and pulled him down to her lower body. With Liu Feng's penetration, Wang Fang let out an "
Oh—"
and lay down on the teacher's desk.
"Sigh,"
Teacher Xiaoyue couldn't help but sigh, "These kids nowadays, really..."
The classroom was immediately filled with the sounds of flesh slapping against flesh and suppressed moans.
Wang Fang's snow-white, full body lay on the teacher's desk, her hands involuntarily gripping the edge of the desk. Her
waterfall -like hair was spread out over the desk, swaying with each impact. Wang Fang's foxy
eyes became hazy, staring blankly at the ceiling, her dry lips slightly parted, occasionally letting out
moans .
Those precocious breasts swayed with each impact, wave after wave… “After a girl becomes sexually aroused
, her nipples will stand up, everyone pay attention. At this time, the woman’s whole body will turn slightly red, her skin will
become , her labia will swell, and her vagina will secrete a lot of fluid, which helps the penis to enter. Hehe, Wang Fang
’s fluid is quite plentiful…”
By this time, Wang Fang’s vaginal fluid had already flowed down her buttocks onto the lectern, and Liu Feng’s penis was even more wet and
glistening .
Wang Fang had long since forgotten about her teacher's jokes. She had already reached orgasm twice, the first two times she had forcibly covered
her to hold back her screams. With another wave of orgasm approaching, Wang Fang could no longer hold back
and screamed, "Ah, I can't take it anymore, I'm coming again, ah—"
She looked up at Liu Feng's thrusting, then screamed again and collapsed, but Liu Feng's thrusting continued
. Wang Fang's head swayed helplessly from side to side... Teacher Xiaoyue was speechless, staring blankly at
Liu Feng's large penis, thinking about how she had given herself to her university teacher last time... "Young people are just different
..."
At this moment, one of the boys in the seat couldn't hold back any longer. He grabbed his female classmate and laid her down on the desk,
intending to penetrate her as well. Teacher Xiaoyue then realized what was happening and quickly went over to say, "Be careful,
do you know if she's a virgin...?"
The girl just covered her face with her hands and remained silent. As the boy penetrated her, she began to moan softly.
Teacher had just breathed a sigh of relief when she seemed to remember something and turned back to call Liu Feng, "Remember, you're not allowed to ejaculate inside!"
Then she turned back to the boy and said, "You too!"
She was slightly relieved when she saw both boys nod.
At this moment, almost half of the boys in the class started to pin their deskmates down, and a chorus of squeals
and screams filled the air. Teacher Xiaoyue was busy again, and several who struggled fiercely were half-heartedly penetrated
. A few others struggled desperately to have their underwear removed. After questioning by the teacher, it was confirmed that they were indeed virgins, but their underwear
was clearly already soaked. Teacher Xiaoyue said, "Then, let the boys give you oral sex, like I
just did. Boys, please observe your classmates' genitals carefully, don't break the hymen."
Several girls, blushing and dazed, had their underwear removed and lay on the desks… Two girls
cried out to the teacher with pained expressions, "I've started my period…"
"Then, you can give your deskmates oral sex, and pay attention to the male's external genitalia... Classmates! —
"
The teacher looked around at everyone, "Be careful not to ejaculate into the girl's vagina, otherwise she will get pregnant!"
"Teacher, I, I'm in my safe period now..."
A girl next to the teacher said quietly while being penetrated, her face flushed, "Teacher, me too..."
"Me too..."
Several girls whispered.
"Sigh, you're wrong. Using the safe period for contraception has a lot of hidden dangers and cannot be considered the safest method
. Do you understand, male students?"
"Understood!"
Everyone responded in unison, while vigorously thrusting.
The classroom was filled with the sounds of thrusting, and moans rose and fell, some barely audible, some very
loud and wanton, some just moaning and groaning, what a scene of eroticism! With a long moan from Liu Feng,
streams of semen shot onto Wang Fang's body, even reaching her chin. Wang Fang was already
lying , unable to move, and she had lost count of how many orgasms she had had.
"Teacher..."
A boy's voice from behind made Teacher Xiaoyue turn around. Wang Liang looked at Teacher Xiaoyue with a pained expression, "
What are we going to do with two boys at one table? We're not gay..."
Seeing the two already erect penises, Teacher Xiaoyue couldn't help but chuckle. "You two
kids... come here..."
she said, walking up to the podium. Liu Feng, understanding the situation, picked up the almost unconscious Wang Fang to make room for the teacher. Teacher
Xiaoyue once again took off her panties, raised her legs high, and said to Wang Liang, "Come on, young man..."
Teacher Xiaoyue seemed like a tolerant older sister, but seeing so many young bodies moving before her eyes, her heart
was already filled with lust.
The boy was impatient and thrust all the way in, pumping in and out. Teacher Xiaoyue laughed, "
Little boy , so eager, oh, um..."
She wanted to laugh at the boy, but was interrupted by a sudden surge of pleasure and couldn't help but join in the moans
.
Teacher Xiaoyue turned her head and saw Wang Liang watching the two of them having fun, still looking miserable.
The teacher gently pinched Wang Liang's penis with her hand, "You come too, little boy..."
After saying that, she pulled it over and stuffed it all the way in and started sucking. Wang Liang excitedly called out, "Teacher..."
and then involuntarily began to thrust in and out of the teacher's penis.
In the classroom, the students all saw their usually beautiful and quiet teacher lying on the podium, her two long, white
legs draped over a boy's shoulders, her genitals being penetrated by a long penis. One of her shoes had been thrown off, and
her petal-like toes involuntarily opened and closed with pleasure. The boy tightly gripped
the teacher , spreading her genitals open, exposing her labia to everyone. The boy
would occasionally kiss the teacher's feet, even sucking on her white toes... The teacher moaned, playing
with Wang Liang's large penis, letting it slide in her mouth. With a wave of intense thrusting, the teacher spat out the large
penis and screamed, "Ah—it feels so good—I'm going to come again, harder!"
After saying that, she fiercely stroked Wang Liang's large penis. Wang Liang let out a long cry, and after an "oh," he couldn't help but ejaculate! He ejaculated all over Teacher Xiaoyue's head and face, even her lips were covered in semen.
Seeing such a lewd scene, the students became even more excited. Several couldn't resist and ejaculated
on the female students' bodies. The sounds of thrusting, moaning, and shouts of ejaculation filled the classroom...
Suddenly, the classroom gradually quieted down. Following everyone's gaze, everyone looked towards the door. The door
had been opened sometime earlier, and a person stood quietly in the doorway.
Teacher Xiaoyue followed everyone's gaze and was immediately stunned! It was Director Hou, the head of the teaching department, standing in the doorway.
This old woman was hated by both teachers and students. Not only was she incredibly old-fashioned, but she also
dressed . Her voice was cold, and perhaps due to menopause, she was always finding fault with everyone.
Everyone both hated and feared her.
Now that she had discovered their shameful affair, everyone felt a chill run down their spines, and several boys immediately
went limp.
Needless to say, she had noticed the unusual noise and unlocked the door with her key.
Director Hou coldly scanned everyone, snorted, and was about to turn and leave.
Teacher Xiaoyue reacted quickly, ignoring the semen on her lips, shouting, "Don't let her go!" Several
boys immediately understood, rushing forward and pulling Director Hou back.
Liu Feng led the way, tearing at Director Hou's shirt. Director Hou glared and shouted, "What are you trying to do!"
The boys immediately stopped. Teacher Xiaoyue said softly, "This is the only way..."
Liu Feng and the other students gritted their teeth and began tearing at Director Hou's clothes.
Director Hou struggled violently, shaking off everyone, and looked around at the boys. "Fine, I'll do it myself..."
she said, pulling down her pants, followed by her baggy underwear... It was six o'clock in the afternoon,
long after school had ended. The school was quiet, but only when you reached the top floor of the teaching building could you hear some unusual noises coming from the east end
.
Wang Liang sat on the steps at the top of the stairs, his tired eyes scanning the surroundings.
The class had already changed, but the game wasn't over yet, and he wanted to go home.
The group sex in the classroom had long ended. Students sat scattered on their seats and desks. Several
girls, unable to bear it any longer, lay sprawled on their desks. A few pretty girls, after being raped by several boys, lay on
their desks, occasionally twitching, letting semen flow from their genitals down their thighs and onto the desks… Several
less sat dejectedly on their desks, resting their chins on their hands.
Almost every boy's face was blank and tired, staring blankly at the erotic scene unfolding before them.
On the teacher's desk in the classroom, which had been moved aside, lay a shocking scene of eroticism that would leave anyone who
saw it in awe: a boy lay naked on the desk, with Director Hou swaying on top of him.
A large clump of black pubic hair obscured the truth below. Director Hou was rapidly stroking two penises in his hands, one in each hand
, while sucking on a classmate's large penis. The classmate stood awkwardly to one side of Director Hou, as two
other classmates were squatting nearby, each biting and sucking on one of Director Hou's breasts. Director Hou's breasts
were slightly sagging, but even as the boy sat on her, her nipples were still being sucked… Seeing
this erotic scene, Teacher Xiaoyue, sitting on the floor to the side, could only sigh in admiration, only worrying that Director Hou was slaughtering a pig.
Not knowing if her screams would be heard by others, several students were sent to keep watch. This Director Hou, it's unclear if
she has a regular sex life; she seems to have had several orgasms and still isn't satisfied… Director Hou's two
penises ejaculated again, shooting onto her face and shoulders, but it didn't seem particularly noticeable because her body
was already covered in semen stains… “Two more!”
Director Hou said. Teacher Xiaoyue had no choice but to scan the students around her. A boy next to her said with a bitter face, “
I… I’ve already ejaculated twice, first with my deskmate, then with Director Hou…”
Several other boys also hid to the side with bitter faces. “Anyone else who hasn’t slept with Director Hou, come to the front, listen to me!”

Several boys reluctantly came to the front. Teacher Xiaoyue picked two boys, but no matter what she did,
their penises remained limp. Seeing Director Hou's impatient expression, Teacher Xiaoyue had no choice but to say,
“Let your deskmates give you a blowjob, quick!”
The two boys then turned to find their deskmates. At this moment, Director Hou's penis… With a groan, he ejaculated
. Director Hou straightened her back and twisted rapidly a few times, letting the young man's glans churn a few more
times deep inside his vagina... The boy struggled to his feet and hid to the side. Director Hou looked at the fleshy forest of young men around her
and laughed, "Let me have my fill today!"
Teacher Xiaoyue couldn't help but sigh inwardly. She pulled Liu Feng over, squatted down, and began to give him oral sex
. After Liu Feng's penis grew large again, Teacher Xiaoyue vigorously stroked it a few times with her hand, revealing its long shaft.
Slightly throbbing, powerfully swaying, Teacher Xiaoyue patted Liu Feng's buttocks. "Go on."
Liu Feng helplessly lay down on the podium. Director Hou's eyes lit up as he looked at this unusually tall and muscular man
. He quickly sat on him, his lower body already filled with countless men's semen, and thrust deep inside him.
"Oh—oh, so good…this is the best…"
As the boys on both sides arrived one after another, Director Hou grabbed two "armrests" with both hands, put
a "gag" in his mouth
, and began another wave of vigorous shaking! …At this moment, Teacher Xiaoyue realized that Director Hou's buttocks were really
not ordinary. Usually, when he wore baggy pants, it wasn't noticeable, but his pear-shaped buttocks, sitting on the 1.8-meter-tall Liu
Feng, almost covered the boy's body.
The director's skin wasn't fair and was a bit loose, but it was very clean and smooth, smelling of soap.
Director Hou had been divorced for a long time, and Teacher Xiaoyue suddenly felt a little sorry for her, and kept urging the students
to do as the director asked.
Director Hou's long howls were truly earth-shattering. Each time, Teacher Xiaoyue was afraid of being overheard. Everyone
thought Director Hou was finally satisfied, but after each drunken murmur, he would
start , eventually sitting up and down energetically! He would even raise
his buttocks high, looking down at how his long penis moved in and out of his body.
Sometimes he would turn around, sitting on the penis in different directions, writhing and thrusting.
Sometimes he would sit on the penis, looking around at the students with interest, having a row of boys stand in front
of him , pulling on each person's penis and testicles one by one, casually teasing and commenting, occasionally asking
Teacher Xiaoyue's opinion, even asking which boy's penis felt inside her. Teacher
Xiaoyue blushed and answered each question.
When Director Hou noticed his penis was getting soft, he would wriggle his buttocks a few times until
it only then would he be satisfied and start playing with the others.
Suddenly, Director Hou noticed that Wang Manxia, the class monitor who often opposed her, was lying on her desk,
seemingly asleep with a lustful look on her face. However, the semen flowing from her genitals seemed to tell her the reason. "
This little girl," Director Hou thought, "it must be because she's pretty that several male classmates have taken turns with her. "
Thinking this, Director Hou ordered several male students to lift Wang Manxia onto the desk and
spread her legs, fully exposing her clitoris and labia. The pink flesh inside her vagina was even turned inside out.
Wang Manxia struggled and screamed in resistance, but seeing Teacher Xiaoyue's disapproving look, she could only remain silent
and let everyone do as they pleased.
Director Hou ordered all the boys to surround Wang Manxia, and each of them wantonly rubbed
every part of her body. Seeing Wang Manxia's pretty face flushed red, looking aggrieved and wanting to cry, but the pleasure in her body
made her groan involuntarily, Director Hou laughed happily, bouncing her big buttocks up and down,
making Liu Feng beneath her groan as well.
Director Hou then ordered several girls she disliked to climb onto the desks, facing her, and
masturbate until they reached orgasm. Initially, the girls resisted, but under Teacher Xiaoyue's persuasion, they complied
. Some of the girls were clumsy, seemingly never having masturbated before. Teacher Xiaoyue had to walk
over to and whisper instructions. The girls listened blushing, stroking and rubbing their
genitals with their fingers, occasionally inserting their index fingers into their vaginas.
"Don't try to fool me," she said. "Whoever's fluids flow onto the back of their hand means they've truly orgasmed, and then they can get down,
hehe..."
She then involuntarily began to wiggle her large buttocks, making a slapping sound.
Upon hearing this, several girls had no choice but to grit their teeth and get to work. Those who initially tried to bluff their way out had to start kneading themselves with all their might
. Soon, the classroom was filled with the sounds of moans and groans... Teacher Xiaoyue was secretly anxious, wondering when
this would end. The longer it went on, the more trouble it would cause. Teacher Xiaoyue secretly winked at the boys
"serving" Director Hou
. They understood, and two boys sucked on Director Hou's nipples vigorously
while kneading her slightly sagging but still full breasts. Director Hou was sitting
on Liu Feng's penis with her back to him. Liu Feng was thrusting his hips, letting his penis penetrate Director Hou's lower body, while
reaching out to explore behind Director Hou's buttocks... For some reason, Director Hou finally felt
something again, no longer paying attention to the erotic scene in front of her. She was just passionately moving her hips up and down, pressing her hands tightly against
Liu Feng's thighs, occasionally raising her head and panting heavily.
"Ah, so good, such a big cock, I love it, come on, let me feel it again, ah!—oh
, faster, almost there—ah—harder, yes, you two, harder, ah, you're so naughty, daring to reach into my
... ah, so good!"
Between thrusts, Liu Feng's penis swelled exceptionally thick, glistening with a white fluid. Each time it was withdrawn, the glans was clearly
visible; when he sat down, only his testicles were exposed. Director Hou seemed to possess inexhaustible strength; beneath his thick
pubic hair , his two slightly dark labia were wide open, and a bright red clitoris peeked out,
quite different from Teacher Xiaoyue and the other students. Teacher Xiaoyue and the other students were stunned! Suddenly, Director Hou's body stiffened,
the thrusting sounds abruptly stopped, and with a long cry, Liu Feng and Director Hou simultaneously reached orgasm!
Teacher Xiaoyue inwardly cried out in alarm, knowing that Director Hou's orgasms lasted a long time and this wouldn't be enough to satisfy him.
Teacher then looked back at the other student's penis, which was now usable. Fortunately, several penises were semi-erect. Xiaoyue
was about to go over and pull them away.
Suddenly, Liu Feng flipped over, throwing Director Hou to the ground. He
grabbed a nearby umbrella with a wooden handle, over a foot long, and thrust it into Director Hou's genitals,
twisting . He gritted his teeth and yelled, "You slut! You whore! You bitch, I'll fuck you to death! I'll fuck
you to death!"
Director Hou, still recovering from her orgasm, was so stimulated that she became incredibly absurd, unable to
control herself. She cried out, "Fuck me to death! I am slut, you whore, fuck me to death! Ah—ah—it feels so good
—I can't take it anymore—ah—ah—ah—"
With Liu Feng's rapid thrusting, a stream of liquid suddenly gushed from between Director Hou's labia! Then another stream followed, flowing out in waves. The female students stared wide-eyed,
speechless . Only Teacher Xiaoyue and a few boys realized it was a woman's squirting.
Director Hou, no longer shouting despite Liu Feng's thrusting, simply leaned to one side, closed his eyes, and breathed
heavily, occasionally twitching or convulsing. Liu Feng gradually stopped moving as well.
Teacher Xiaoyue finally breathed a sigh of relief and quickly gestured for the students to help Director Hou get dressed.
Then, she had each girl lie on the table with her legs spread apart. Although they were a little embarrassed,
they trusted Teacher Xiaoyue and complied. Teacher Xiaoyue checked each girl, instructing those who had accidentally ejaculated
inside to take emergency contraception. Thankfully, no one was injured.
Only then did the teacher return to the podium, where students had already set up the desk.
"Class, today, something unexpected happened in our physiology and hygiene class. However, I believe
you all have gained a better understanding of your own and the opposite sex's reproductive systems. I hope you will wash yourselves thoroughly when you get home,
and promise not to tell anyone else. Do you all understand?"
After receiving a chorus of agreement, the teacher nodded in satisfaction, then smiled and
said , "Today, no new cases of hymen rupture occurred in our class. There are still three virgins, which is
very good. Next time, I hope these three girls will demonstrate the physiology and hygiene of the hymen for us..."
The three girls blushed instantly. One girl still had someone's semen hanging around her neck. The three
girls nodded shyly at the same time.
Watching everyone rustling as they put on their clothes, one girl handed the teacher her underwear. Teacher Xiaoyue then
realized that she was still completely naked, except for a pair of sandals on her feet. She exclaimed "Oh!" and quickly put on her clothes
. The students smiled knowingly.
Two boys helped the nearly unconscious Director Hou home. Then, the students gradually
left the classroom. Teacher Xiaoyue opened the window to let the lewd smell dissipate.
I thought to myself, this is truly an unusual sex education class.
The young, mature bodies of my classmates floated before my eyes, then past Director Hou's cold face and wanton physique. I didn't know whether to look forward to or worry about the next sex education class…
