After math class the next day, because my grades were not ideal, I was kept behind for tutoring until 9:30 pm. I also
watched as Teacher Li Zhenzhen, who had just finished work, left the tutoring center. I was sure that she would not have to stay behind for extra "tutoring" by Director Jiang Wangcheng.
Only then did I feel relieved and happily rode my bicycle home.
Teacher Li Zhenzhen must be the so-called training teacher, right? Usually, she compiles handouts at the tutoring center, observes other
teachers' video training methods, and does some administrative and cleaning work in her spare time. She is called a full-time teacher, but
in reality, she is a cheap laborer at Bedford. Her salary is several times better than that of part-time students, but compared to the real big-name teachers,
her income is less than half of theirs. Huh? The back of that person pulling the motorcycle looks familiar? No way, isn't 　　that Teacher Li who left in front
of me 10 minutes ago ? "Teacher?" 　　I slowed down my bicycle and rode up to the teacher. 　　"Hehe, out of gas." 　　The teacher stuck out her tongue, completely lacking any teacherly demeanor, treating me almost like her college classmate, 　　acting like a silly goose. 　　"Then I'll ride off to buy some gas. What kind do you want? 95?" 　　I estimated there was a gas station a few kilometers away, but at this rate, it would take the teacher a long time to walk there, 　　so I figured I'd ride off to buy some and come back to fill it up for her. 　　"No, no need," 　　the teacher quickly waved her hand. 　　"It's okay, I'm often kept late from work, my mom won't be surprised if I'm a little late." 　　Saying that, I started riding towards the gas station. 　　"Really, no need!" 　　The teacher's scream made me brake suddenly, and I quickly swerved back to her side. 　　"I forgot to bring any money, I have to take it home to get some." 　　The teacher lowered her head shyly. 　　No way, how unlucky, I forgot to bring any money and just happened to run out of gas. 　　"It's okay, I have money." 　　I patted my pocket; I still had a few hundred dollars left in my allowance. Gas shouldn't cost that much, I thought. 　　Ignoring the teacher 　　's calls of "Xiaoping, Xiaoping" behind me, I rode to the gas station, filled my water bottle with 95-octane unleaded gasoline, and then 　　rode back to find the teacher. 　　"Here you go!" 　　I handed the water bottle to the teacher. 　　"Thank you, you're so kind." 　　The teacher smiled at me, then added the gasoline to the tank and started the motorcycle for a while before it was working again. 　　"I'll leak the test questions to you before the next quiz!" 　　the teacher playfully said as a thank you for my kindness, but it held no appeal. My mom only cared 　　about school grades; even if I got a zero at the cram school, she wouldn't mind, after all, it was "Bede Gifted Academy," 　　full of weirdos. 　　When I think of those perverts, I don't picture 　　Tang Chenwei and Chen Yuhao, who bullied me for over a year and were ranked in the top 10 of the school, nor do I picture Zhen Shuzhu, the school beauty from the private girls' high school whom I used to glance at several times a day 　　. Instead, I picture Li Fa, whom I only met once. This guy, with his seriously problematic personality and mental state, is what you call a pervert 　　, right? I think he's like what people call Asperger's syndrome or something, with a social anxiety disorder. 　　Hehe, I'm pedaling furiously on my bicycle; I'm still so far from home! Huh? It's you again? I rode to a 　　bridge over a wild stream and saw Ms. Li Zhenzhen's motorcycle parked by the roadside. She was pacing back and forth on the bridge. 　　"Teacher, what's wrong?" 　　I followed her pacing back and forth, looking down the bridge to see what she was looking at. 　　"There's a puppy." 　　The teacher went around to the embankment to see if there was a way down. 　　Huh? It really is! There's an ugly little dog under the bridge, staring longingly up at the top. 　　It was past nine o'clock at night. Teacher, you must have incredibly sharp eyesight to have spotted it! 　　Just as I came to my senses, the teacher had already found a way down through the bushes. But that dog was so 　　stubborn. It had been lying in the shallow stream looking like it was waiting for rescue, but as soon as the teacher 　　finally overcame all obstacles and made its way down, it ran away, arrogantly keeping a distance from her. 　　"Xiaoping, come down and help!" 　　the teacher's clear voice called from below the bridge. 　　"Okay." 　　No good stuff, but lots of pictures. Resigned, I followed the path the teacher had taken down the bridge, and in the blink of an eye, I 　　was covered in grass clippings and beggar-ticks. 　　"Chase it over from over there," 　　the teacher instructed me to surround the stupid dog. Although the stream only reached our knees, after the chase, we 　　were soaking wet, dirty, and smelly. Luckily, the ugly dog must have been a pet; although it 　　was somewhat afraid of us, when we finally grabbed it with all four of our hands, it 　　didn't resist, only letting out a slight whimper. It simply let us carry it onto the bridge. 　　"It must have been abandoned. The owner probably left it under the bridge to prevent it from following them," 　　the teacher said sadly, looking at the dog by the roadside. The dog, certain it was out of danger of drowning or starving, 　　didn't even say thank you before running away along the road. 　　"Hmph, not even a thank you," 　　I muttered, watching its retreating figure alongside the teacher, realizing I was indeed a few centimeters shorter than her. 　　"Hey, buddy," 　　the teacher gently tapped my head. Dogs, of course, don't say thank you. 　　"Thank you, Xiaoping." 　　The teacher gave me a warm smile, but I didn't dare look her in the eye. Her already revealing outfit 　　, soaked by the stream, was practically just underwear; her black bra was clearly visible through her top under the streetlights 　　. 　　"I also thank you on behalf of the dog. If you hadn't found it, it would be dead." 　　Actually, I quite like dogs. Although I don't have one at home, I love playing with stray dogs on the street, and I even 　　buy them food when I have extra pocket money. 　　"Hehe, respect for life, right?"

The teacher noticed her black bra was exposed again, but she didn't seem bothered and pointed to her dimples with both index fingers, trying to look cute
.
"How far is it to your house?"
the teacher asked with concern, noticing I was also soaking wet.
"About another half hour riding along this road,"
I replied, pointing to the seemingly endless road.
"Wow, that's a bit far,"
the teacher said, putting her hand to her chin in a thoughtful gesture.
"Lock the bike."
Huh? The teacher suddenly made this request.
"I'll take you to my house to shower and dry your clothes before we go back."
With that, the teacher grabbed my hand and tried to get me on her scooter.
"No, no, no need."
As a middle school kid, my first reaction to any request from an adult was always no, but
I regretted it as soon as I said no. After all, being able to go to the teacher's house felt like a privilege,
the only thing I had that set me apart from everyone else in the year or so I'd been at Bethlehem.
"Even our new classmate Li Fa knows that riding a bicycle soaking wet will make you catch a cold, and you live so far away. If you catch a
cold, you won't be able to study properly for several days, and you won't be able to see your tutor and classmates. Is that okay?"
The teacher's almond-shaped eyes widened as she reasoned with me, appealing to my emotions. But
I was actually happy not to see my tutor and classmates. Wait, that would mean I wouldn't see Teacher Li Zhenzhen and Li Fa either.
I don't know what got into me, but hearing Li Fa's name made me lose all will to resist, letting
the teacher pull me onto the motorcycle.
"Hold onto my waist."
The teacher grabbed my thighs, making sure my feet were properly on the footrests, and that my hands had something to support them—
she was very concerned about my safety.
"Isn't that inappropriate?"
I didn't dare touch the teacher's waist. Faced with this awkward situation, I suddenly wanted to get off the motorcycle.
"You little brat, I'm not afraid of you anymore, what are you afraid of?"
The teacher found my attempts to maintain proper boundaries between men and women amusing. But I'm clearly not a child anymore; I
even ejaculated on your tongue earlier! So, acting as if it were no big deal, I placed my hand on the teacher
's slender waist, inhaling her youthful fragrance and feeling her warmth in my palm.
In less than two minutes, we arrived at our destination, which seemed to be a suite rented to students from a nearby teachers' college.
The teacher took out a key to the iron gate and opened it; we went upstairs and entered one of the rooms.
The suite was quite small, roughly the size of my room; the toilet/bathroom was tiny, a single
bed took up almost half the space, leaving only room for a desk and shoe cabinet, and then a narrow aisle.
However, it was clear the teacher was very clean; the floor was spotless. What pleased me even more was that there wasn't
a single male item in the room, presumably because the teacher didn't live with her boyfriend, and he didn't come here often. "Wait a
moment, I'll change my clothes,"
the teacher said, taking her clothes into the bathroom. A minute later, she changed into a short-sleeved t-shirt and shorts, then
asked me to go into the bathroom, take off my clothes, and hand them to her so she could wash and dry them; she also gave me a clean change of clothes
, which were what the teacher usually wore.
"It's okay if you don't wear underwear for a little while, I'll give it back to you after I dry your clothes."
The teacher's voice came from outside the door. The countryside was indeed very quiet at around 9 pm; I couldn't hear
any other sounds. The teacher's footsteps faded into the distance; it seemed she was going to the shared coin-operated washing machine and dryer
to dry my clothes.
I'm not used to using the showerhead; I prefer to fill a bucket with hot water and scoop it out one scoop at a time. A large
bucket is just the right amount for my shower.
So I turned on the tap and, before filling the bucket, curiously looked around the teacher's bathroom
.
The teacher definitely didn't live with her boyfriend; her sink only had her toiletries. There weren't
any men's shoes in the entryway either. However, there was a razor on the sink. I was a little sad when I first saw it, but then
I realized it was probably for shaving armpits. Sure enough, the hair near the blade was fine, unlike the coarse
hair on my dad's razor.
Just as I was about to start showering, I noticed the teacher's clothes in the basket.
Tsk tsk, how careless of you! Letting a budding kid like me into the bathroom, how could you not take her
underwear with you?
Looking at the teacher's black underwear, I thought about how just a minute ago I'd been touching her beautiful genitals. I recalled
how Director Jiang had almost taken her vagina the day before, and just seeing her secret place made my blood boil.
It truly has an alluring power! The teacher's genitals were a darker color than Li Fa's, but I knew
that was inevitable. Even at 13, my foreskin was already a bit dark and dirty. When I'm in my twenties,
my penis will turn dark, no longer a pink little thing—that's to be expected.
I picked up the teacher's underwear and saw a small white object in the crotch area, with
sticky, slippery secretions on it. Could this be a sanitary napkin? But if it's a sanitary napkin, why
isn't there blood? Thinking about what I did to the scantily clad pictures in the past, that impulse rekindled within me. Although I knew
I could never have any further interaction with the teacher, I still wanted to possess her. I wanted her to be imbued
with my scent, I wanted her to take my shape.
So I pulled back the foreskin of my already hard penis slightly, but found that I still couldn't fully expose it.
It would be too painful to pull it down, so I only exposed the urethral opening. I didn't have the courage to actually let the urethral opening touch
the side of the teacher's penis that was covered in secretions, so I turned the teacher's underwear right side out and aimed the glans
at the center of the teacher's crotch, the triangle area that was usually hard to see. I imagined that this was the teacher's real vulva, and then I put
the urethral opening up and gently rubbed it against this place that had been in close contact with the teacher's genitals just a few minutes ago. "Ahhhhhh,
teacher..."
I imagined that I had entered the teacher's vagina. Although I don't masturbate and have never watched porn, I
know the beauty of sex, especially since my sexual fantasy object is such a beautiful
teacher with such a good figure and a kind heart, such as jumping off a bridge to save a dog.
I twisted my waist, recalling the scene yesterday where Jiang Wangcheng almost violated the teacher. Although my glans was only pressing
against the teacher's panties, it felt like Jiang Wangcheng's glans was pushing open the teacher's labia, preparing to gradually
penetrate.
Even though I was actually just holding my penis and poking at the crotch of the teacher's panties, I knew that if my entire penis
were inserted into the teacher, I would gain unparalleled pleasure, both psychologically and physiologically.
"Don't know how to turn on the hot water? I'll help you."
Just as I was still indulging in the pleasure of fantasizing about the teacher, the bathroom door suddenly opened. Damn, how come I didn't hear
the teacher's footsteps coming back! Ah, it was covered by the sound of the washing machine! Her footsteps were clearly
audible when she went out, but when she came back, the washing machine was making a noisy sound. I was so engrossed in erotic
things that I overlooked it and didn't even notice! "Oh, it's okay, I thought you used the showerhead."
The teacher noticed that I had already filled the hot water and casually closed the bathroom door.
But the teacher clearly glanced at my erect penis and noticed the tip of my penis pressing against the crotch of her underwear,
yet she acted as if nothing had happened and immediately closed the door. However, her eyes flickered noticeably; I wonder what she was thinking now.
Startled by the teacher's reaction, I lost all interest in fantasizing about her, and I didn't know how to explain what I had just done
. Should I just force myself on her to shut her up? Haha, being shorter than her, I probably couldn't possibly beat her!
Neither gentle nor forceful methods worked; my little penis immediately went from proudly erect to listless. I quickly showered
and put on the clothes the teacher had given me.
Sigh, even an ugly daughter-in-law has to meet her in-laws eventually. After showering, I thought for a moment and decided to handle the incident calmly,
without mentioning it at all.
"Your clothes aren't finished washing yet, wait a little longer."
As I walked out of the bathroom, the teacher was listening to music on her computer.
The teacher was operating the computer with the mouse, and I got another glimpse of her cleavage from the side.
Looking through the sleeve of her t-shirt, I could see her snow-white breasts—she wasn't wearing a bra—jiggling with her movements.
Many women are like this at home, right? I once saw a hot mom at a tutoring center who
went out in just a t-shirt after showering, and I could see two raisins through her clothes.
Besides, the teacher had only gone in to change to avoid making a mess; she hadn't even showered yet. How could she possibly
put on a new bra just to help me wash my clothes?
"Xiaoping,"
the teacher suddenly turned around. This time, she probably didn't notice me staring at her breasts. After all, from my perspective
, it was both her large breasts and the computer monitor—the " 　　straight-line travel of light" mentioned in the first section of Chapter 4, "Light and
Color," of the third volume of physics and chemistry. 　　"Come sit here," 　　the teacher patted her single bed, gesturing for me to sit on it. 　　The single bed was right next to her computer desk. She sat in the chair, and I sat on the bed, only inches away from her. 　　At that moment, a slow song was playing on YouTube; the melody sounded quite nice, so I 　　casually asked the teacher, "What song is this?" " 　　'A Single Thought of Obsession,' the theme song of 'Scarlet Heart,'" 　　the teacher replied casually. 　　The line "It's the fault of time that we can only miss each other" 　　made me think of my interactions with Teacher Li Zhenzhen. Sigh, why did I 　　meet such a beautiful girl when I was a kid? If she were a college classmate or a colleague, I would definitely pursue her! (Wake up, you 　　'll just be a fat otaku when you grow up!) "As your teacher, although I'm not much older than you, there are some principles 　　I must teach you, so they will help you when you enter society," 　　the teacher suddenly turned her chair around and said seriously. Given the height difference between the chair and the bed, and our own 　　height difference, I knew she was about to lecture me. 　　"Tell me honestly, what were you doing in the bathroom just now?" 　　The teacher's tone was a little embarrassed, and she sounded a little trembling. 　　Honesty is the best policy; I had memorized this phrase in English. Although I often treated the teacher like a female animal 　　and thought about having sex with her all day long, she was still a teacher, and a teacher at the terrifying "Bede Gifted Academy 　　." I only realized now that if this matter got out of hand, the most serious consequence would be expulsion, and 　　my parents would definitely kill me! So I decided to tell the truth! "I was doing dirty things to the teacher's underwear." 　　I lowered my head, even though I could see the teacher's nipples vaguely if I looked up, I still tried to reflect on my actions 　　and temporarily refrain from taking advantage of the teacher with my eyes. 　　"Masturbating?" 　　The teacher's tone was trembling, but it was probably not because she was angry, but because it was the first time she had encountered such a thing, and she was embarrassed 　　and didn't know how to say it. 　　"I don't masturbate." 　　Actually, I was only 13 years old, so it wasn't surprising that I didn't know how to masturbate, but now declaring that I didn't know how to masturbate gave me a 　　sense of upright purity. 　　"Didn't we agree to tell the truth?" 　　The teacher raised her voice slightly as she questioned me. 　　"I really didn't." 　　To prove I wasn't lying, I looked up at the teacher's eyes, my peripheral vision catching glimpses of 　　her barely visible nipples. 　　"Then why are you holding my underwear!" 　　The teacher blushed, but since the student had done something wrong, she had an obligation to reprimand him, no matter 　　how embarrassing it was to say it aloud. 　　"I just put my penis on it," 　　my voice was muffled by the sound of the washing machine. 　　"So you weren't masturbating?" 　　The teacher seemed calmer now, her arms crossed over her chest, the tighter her clothes making her breasts and nipples 　　even more clearly visible. 　　"Yeah." 　　I felt a sense of relief, like I'd been given a reduced sentence, like a life sentence. 　　"If you weren't masturbating, why did you do it?" 　　the teacher asked, frowning. 　　Actually, at my age, there are probably quite a few people who masturbate, some wanting to prove...

Knowing they're adults, they use masturbation and even sex to declare their maturity. But physical satisfaction is
secondary; it's essentially just childish behavior.
Like Chen Yuhao, Tang Chenwei, and Huang Ruoli, they talk a good game, but with so much academic pressure, the best
thing is to have something new every day, constantly watching Sato Haruki and Uehara Ai, thinking they're
sophisticated by choosing porn.
"I just want to do things others can't do,"
I said subtly. Actually, I wanted to possess all the pretty girls I could see, even without the pleasure of ejaculation
. But being able to declare "that's mine" in the most unseemly way
was more appealing than physical orgasm.
"You can get first place to prove others can't do it,"
the teacher said.
"It's not like I don't try, but they're just too good!"
I argued. Actually, if I used the time I spent playing games like Tower of Saviors and online LoL on weekends to study, maybe
I'd have a chance.
"Then come to the tutoring center often. I'll definitely teach you well. I can't guarantee anything in other subjects, but you
must get the highest score in physics and chemistry!"
The teacher put her hands on my shoulders, looking into my eyes with burning determination, but I didn't know where to look
. "There's one more thing."
"What?"
I breathed a sigh of relief. It seemed we were going to talk about something else, so this matter could be downplayed.
"Did you run out of tissues to wipe your sweat in class yesterday?"
The teacher suddenly asked with a stern face.
Right, I remembered that hellish class yesterday. Every single one of us had used up all our tissues wiping away sweat
.
"Yeah."
I answered nonchalantly.
"And when you went downstairs yesterday, you told the headmaster that you were looking for tissues in the dark after using the restroom?"
This time, the teacher didn't dare look me in the eye; she stared at my body.
"I..."
Damn, I couldn't lie this time. I couldn't admit that I had been watching for a long time! "Did you
see everything?"
The teacher blushed, her earlobes and collarbone flushed, but her voice was slightly choked.
"Don't you think I'm shameless, doing this even though I have a boyfriend?"
The teacher's eyes were already red, and her body was trembling, but she tried to hide her distress and
spoke calmly.
"No, it's the headmaster's fault, and you were just studying, weren't you?"
Damn it, I knew perfectly well that the teacher had succumbed to financial pressure, yet I still went against my conscience and gave her a way out.
"That's right, it's so good that you understand my good intentions. Yesterday, I was trying to learn classroom management
techniques for tutoring centers, not doing anything shameful; I only used those
methods in class because of teaching needs. I didn't do anything wrong to my boyfriend, did I?"
The teacher sniffled and wiped her tears with a tissue.
"I know, I know your good intentions, teacher. Don't worry about what others think, at least I'm
doing very well in my physics and chemistry classes."
It was the first time I'd seen a young woman cry in front of me, and I stood up, my mind filled with nothing but wanting to comfort her;
I was willing to say anything, no matter what.
"By the way, Tang Chenwei, Chen Yuhao, and Huang Ruoli also had a lot of fun." (
What a joke!) I hadn't talked to them about this at all, but a little white lie might help the teacher
stay strong at this moment.
"Hmm, you're the most understanding, you know the teacher's good intentions. You should explain it to everyone when you have the chance."
The teacher didn't seem so agitated anymore; although she had cried, she was still presentable.
From my elevated position, I easily peered through the
loose neckline of her t-shirt and saw that beneath her flushed collarbone, her large breasts were still fair. The two nipples adorning her fair breasts
weren't the usual small, cute shape blending into the areola, but rather
erect and engorged like when she was aroused yesterday! Seeing this, a wicked thought popped into my head.
The teacher seemed to feel guilty towards her boyfriend for her physical infidelity, but she insisted that she was
still faithful in spirit and that everything was for teaching purposes. If I went along with her thinking, would she
try to meet my "learning"
needs? This proved that she was indeed only dressed provocatively to attract students, and that giving students oral sex was just to
obtain experimental equipment.
"Teacher, can I ask you a question now?"
I pretended to be an eager teenager, looking earnestly into her eyes.
"Of course,"
the teacher said, taking out paper and pen to explain.
"Teacher, I don't quite understand unit conversions,"
I continued, "If a steel ruler is calibrated in winter, will the reading be higher or
lower in summer?"
"This is due to the thermal expansion and contraction of objects. If the unit is enlarged, the number decreases; if the unit is reduced, the number enlarges.
The steel ruler is enlarged in summer, meaning the standard becomes larger, so the number will be smaller, and the reading
will be an underestimation."
The teacher carefully drew a comparison diagram on the paper.
"Teacher, I don't understand, can I borrow this?"
I said, pulling down my shorts, instantly revealing my limp penis.
The teacher was momentarily surprised, but I quickly put her at ease: "Teacher, is there a ruler here? Let's
measure the length of my penis first, and then measure it again after it's erect to see how the readings are converted."
I made it seem like I genuinely wanted to learn.
"Ah."
The teacher was almost angry, but seeing my serious expression, coupled with Huang Ruoli's superb acting
skills in the first lesson—this was the second time she'd seen a student's penis—she wasn't so surprised anymore.
"Hehe, but that would be the opposite; you'd magnify the object, but the ruler wouldn't be longer."
The teacher found a ruler, but didn't actually measure the length of my penis.
"Hmm, we learned that measurement doesn't require international standard units; any reasonable length can be measured using..."
"We can measure things like how many hand spans a desk is, or how many bamboo poles a building is tall,"
I said, pretending to be serious as I stood next to the computer desk, wanting to compare how many erect
penises the desk was equivalent to.
"How long are you going to keep comparing like that?"
The teacher, hands on her hips, couldn't help but laugh at my clumsy actions.
"Then, teacher, can I find an object that's close in length to measure it?"
I said, pretending to look around, finally fixing my gaze on the teacher's crotch.
"In nature, the object closest in length to a penis is the vagina."
I pretended to be an innocent young man unaware of such matters. In fact, my actions towards her underwear,
though crude, weren't excessive. Perhaps Teacher Li Zhenzhen genuinely thought I was just eager to learn and simply wanted to monopolize the teacher
, not to release my lust. "Hmm."
The teacher's eyes flickered, but refusing now would prove that her previous behavior was genuine
infidelity, not something for teaching purposes. So, she almost without hesitation took off her shorts. Sure enough,
like her upper body, to save time, she hadn't changed into new underwear. Now, with her shorts off, her pubic area, with a small patch of dark hair hanging down,
was fully exposed before me.
I walked to the teacher's side, straining to stand on tiptoe, and used my penis to measure near her pubic hair. Because
this position was against human biomechanics, I trembled unnaturally.
The teacher noticed my discomfort and lay down on the bed, but her legs remained tightly closed.
I climbed onto the teacher, straddling her with my legs spread wide, facing her with my most unsightly part. Then
I placed my penis on her mons pubis, aligning the base of my penis with the point where her legs met. This way,
the tip of my penis didn't even extend beyond the area of her pubic hair, meaning her pubic hair was longer than my penis.
"Hehe, even one of your pubic hairs is longer than my penis,"
I laughed like an idiot.
"It'll be much longer once it gets bigger,"
the teacher replied with a forced smile.
"Right now, I don't know how many penis lengths your vagina is, so I'll make a mark."
Saying this, I lay down on her lower abdomen and licked her pubic hair with the tip of my tongue. The fine hairs, moistened with saliva, lay smoothly
together, indicating roughly where the tip of my penis would be if it entered her body.
"Teacher, where is the bottom of your vagina?"
I suppressed my excitement and asked the teacher to point out the deepest part of her vagina so I could see.
"I don't know, maybe around here?"
The teacher casually gestured, and it was almost exactly the same spot as the place I had just moistened with my saliva.
"Isn't that exactly the same as my penis? If my penis gets longer, then I won't be able to insert it all the way in?"
I feigned surprise.
"Teacher, your gesture is inaccurate. Let me try."
Saying that, I spread the teacher's thighs apart, knelt in front of her vulva, and continued to pretend to be eager to learn
, while trying to suppress the urge to get an erection. In fact, my penis was already slightly engorged with blood.
The teacher wanted to stop me, but seeing that my penis was still soft and I couldn't do anything fancy, she
continued to lie on her back with peace of mind.
I excitedly examined the teacher's vulva. Between her fair thighs was a darker-colored organ, which
became darker and darker from the pink on both sides to the area near the so-called vulva. The part on the inner thighs was even close to
brown. A fold peeked out from the gap, and it was impossible to tell that there was a vaginal opening.
Above the folds was a small bump, which must be the clitoris. I gently touched it, and the teacher
shuddered, quickly leaning back to see what I was doing. However, she didn't stop me because my groin was still a
soft, pliable mass, harmless.
I gently rubbed the folds and discovered that they were two intertwined folds. Pulling the two folds apart
, the center was a captivating pink, contrasting excitingly with the surrounding erotic brown
. Those folds must be the labia minora.
So that's where the vaginal opening was! I finally answered a long-standing question, but then I immediately realized that there were actually
two holes hidden in that pink flesh. The upper opening protruded slightly, was rounder and smaller,
while the lower opening extended downwards and was larger. However, the so-called opening was actually just a depression squeezed together by a bunch of pink tissue
. I think the upper one was the urethra, and the lower one was the vaginal opening.
I guided my not-yet-fully-erect penis towards the teacher's opening, only to find it impossible to penetrate; it was incredibly
tight! However, I seized the opportunity, rubbing the tip of my penis against her vulva several times, a
sensation hundreds of times more pleasurable than doing similar things to cold, revealing pictures in magazines, because her
tender organs were warm.
"It won't go in,"
the teacher said, beads of sweat forming on her forehead. She knew it was impossible before I was erect, but she was also afraid of
accidents; if I actually went in, it seemed a bit excessive for teaching purposes.
However, my desire to possess the teacher had reached its peak, so I tested it with my index finger, finding
that a little pressure could open the pink slit, clearly revealing the shape of the opening. But
I had only inserted one knuckle when the teacher warily stopped me.
"Hey, weren't we supposed to use my penis to measure?"
"Oh, but I can't get in, so I can't measure the length of your vagina."
I focused intently on observing the teacher's genitals, my hands also restlessly fiddling and touching, trying to understand female anatomy.
I pulled back the foreskin of the teacher's clitoris, then touched the teacher's labia majora and minora, until the teacher's labia minora
became engorged and spread open, no longer folded up as before, but pink and glossy.
This time, I had already probed the location of the teacher's vaginal opening with my index finger, and my penis was no longer just a wrinkled
ball of sushi, but had already become a small, fleshy rod about ten centimeters long.
"Teacher, there's something stuck in your bangs, let me help you fix it."
I quickly pretended to help the teacher fix her bangs, making her close her eyes so that she wouldn't discover that my penis
was now aggressive! While touching the teacher's bangs, which had nothing on them, with my right hand, I held my left hand...
I tightened my small but firm penis, letting half of the glans protrude, and then thrust it into the teacher's vagina! The teacher
felt something enter her body and quickly opened her eyes, arching her back as if to do something. I, however, temporarily
ignored the sensation in my lower body and shouted, "Teacher, don't move!"
This is what you call the villain accusing the innocent first. I kept my penis inside the teacher's vagina, leaning over her upper body, and
asked with clear eyes, "Teacher, where is the tip of my penis now?"
The teacher stopped struggling, letting my penis remain inside her vagina, which already had a boyfriend. Then, feigning composure, she pointed to
her lower abdomen: "About here."
Actually, it was exactly the same spot she had pointed to, but to make her think we were just discussing
homework, I pretended to suddenly understand and said, "Teacher, I understand!"
My lower body, however, was restlessly wriggling slightly.
"How so?"
the teacher asked, trembling, because of the warm, not-too-large but enough to give her pleasure inside her vagina
.
"Before it got bigger, my penis was so short. From the entrance of your vagina to this spot,
it was roughly the length of my penis. Then, my penis got longer, and it felt like your vagina got shorter.
Counting from the entrance to where it was just now, it only reached the base of my glans. This means that as the standard unit gets bigger, the number gets
smaller. Your vagina is less than the length of my penis!"
The principle is incredibly simple; I just wanted to lose my virginity.
"Congratulations on learning! Can you get up now?"
The teacher arched her back, her furrowed brow telling me she was suppressing pleasure, forcing a smile to
end this absurd teaching discussion.
"Wait a minute, teacher, didn't you teach us that to make the measurement results closer to the actual value, we have to do it several times?"
Looking at the part where we were joined, I now understood how much pleasure her body gave me.
The instant I entered my teacher's vagina, I knew my foreskin had retracted, pushed back to the base of my penis.
Only my penis itself truly broke through and entered her vagina—it was truly astonishing ! I hadn't realized
the power of a woman's vagina was so great! Even now, I still can't believe I've entered her body. The feeling of my penis—
wet, warm, and tight—made me focus all my attention on my lower body, my brain almost oxygen-deprived and unable to think.
Only after I slightly withdrew my penis, confirming that my penis and my teacher's vagina were now one, and as I
pulled my penis out, part of her labia minora was also pulled out, did I finally realize that I had
successfully transformed from that brat who only knew how to touch the triangle area of a picture with the tip of his penis into an adult.
I want to tell all the gifted students who get better grades than me in tutoring classes that I've reached the pinnacle of life a step ahead of you
.
Looking at my teacher's feigned composure, it wasn't a question of possession anymore; I wanted to see
what unknown sides she had.
Would a teacher who usually reprimands students with a stern face also show a lewd expression when being penetrated? The teacher
, always so serious and proper, would moan and groan when being penetrated to orgasm? So, I pretended to be just repeating
the measurement steps, pulling my penis out of the teacher's vagina and then gently tracing the spot she had just indicated with my fingernail
.
"Again."
I inserted the glans into the teacher's vagina again. This time, because of previous experience, it was easier to enter.
After the glans was inside the teacher's body, I immediately lowered my hips to make sure the entire penis was submerged, with only the scrotum still outside
the teacher's body. Then I pushed forward a few more times, ostensibly to determine the position of the tip of the glans, but in reality,
I just wanted to enjoy the pleasure of intercourse.
"Which way?"
I looked up at the teacher, asking her to point out where the tip of the glans was this time. "Are you sure?" Actually, this had nothing to do with the experiment; I just wanted to hear 　　what
the teacher's voice sounded like with a penis inside her vagina . 　　"Mmm." 　　At this point, the teacher's cheeks were flushed, her temples were completely wet with sweat, and her voice 　　trembled uncomfortably. 　　"Okay." 　　I gently etched a mark on the teacher's mons pubis again, just to reassure her through the contact. 　　"Again." 　　So I naturally pulled out my penis and thrust it in hard again, actually wanting to use this practice to grasp 　　the key points of penetration. I've heard that even after losing their virginity, many men still can't penetrate a woman's vagina on the first try, 　　just like a USB flash drive is hard to insert perfectly the first time. 　　"Xiaoping." 　　This time, before I could entice the teacher to speak, she took the initiative to call me by my "stage name. 　　" "Not inside." 　　The teacher's voice was so muffled that it took me a while to understand what she meant. 　　"Don't ejaculate inside." 　　The teacher almost pleaded, looking at me with her watery eyes. 　　"How could that be? I'm just measuring, I don't feel anything else." 　　Although I said this seriously, I had to admit that after the experience of ejaculating last time, I knew 　　that with each penetration, plus the twisting and squeezing after insertion, I would reach orgasm after a few more movements, 　　but I acted nonchalant. 　　"Teacher, I've measured twenty times." 　　Officially, it was just twenty times of withdrawing and inserting the penis into the vagina, but for a middle school 　　student who had just lost her virginity, it was already quite a challenge, especially considering I was also secretly making small thrusts inside. 　　Plus, the teacher was only a girl in her early twenties at most, and the tightness and vitality there were unbearable. 　　Not to mention, this was the first time I'd felt such warmth from my tutor, especially the undeniable 　　heat inside her vagina. 　　"Teacher, thank you." 　　After the twentieth measurement, I looked at the twenty faint nail marks on the teacher's lower abdomen. I knew that 　　until the marks disappeared, the teacher couldn't possibly have sex with her boyfriend again; otherwise, there was no way to explain these marks. These past few 　　days, the teacher belonged only to me! Then an even more wicked thought arose within me. This wasn't just the discharge from the urethra.

It's not as simple as just touching her genitals; I want to completely and truly possess my teacher! "Teacher, one more question."
I was reluctant to pull out my penis, so I left it inside her vagina while watching her
feigned seriousness despite her obvious pleasure as I asked the question.
"In the mixture calculation of an aqueous solution, why do we divide the total mass of the solute by the total mass of the solution? Like last time,
when I added saline solution to my semen, I knew it became diluted. But why not just use
the mass of the saline solution as the denominator and the semen as the numerator? We can still know it became diluted, right?"
I pretended to be a studious young man, even bringing up the absurd experiment from before as teaching material. On one hand, it was to boost
the teacher's confidence, to let her know that her teaching method was correct and that the student was indeed learning well, so that we would
continue to have an endless supply of saps in the future.
"But what if the mass of the saline solution added is very small? Wouldn't you think that the mass of the saline solution is less than that of the semen, so
the semen concentration is actually higher?"
The teacher's eyes were almost full of lust, but she still looked at me seriously as she answered.
"Oh, that's why the teacher kept emphasizing that when mixing, you add up the total mass of the solutions
as the denominator and the total mass of the solute as the numerator to calculate the new concentration. So, my semen was originally so concentrated, but
when mixed with the teacher's secretions, because the semen mass didn't change, but the total mass had to be calculated by adding the teacher's secretions,
the concentration became diluted."
After I finished speaking, my eyes lit up as if I had discovered a new continent, but my crotch began
to thrust vigorously without any restraint.
"Xiaoping, what are you doing!?"
The teacher's terrified expression intensified my animalistic desires. I gripped the teacher's knees tightly with both hands, spreading them as wide as possible
, pretending not to understand that the teacher wanted me to stop.
"No! No! Don't ejaculate inside!"
The teacher shook her head and waved her hands. Although her F-cup breasts weren't exposed,
her breasts and nipples were still visible under her thin t-shirt, swaying incessantly due to her resistance.
"Teacher, I suddenly find physics and chemistry so interesting. I want to do experiments to prove that I
understand."
Because of the unprecedentedly high-frequency rhythmic movements happening between my legs, I spoke haltingly,
barely managing to get the words out.
"No! No!"
The teacher struggled to get up, but although I was small, my weight gave me the advantage.
Plus, a small but undeniably present penis was inserted into her sensitive area, so she
couldn't get up. She could only look at me with a terrified expression, screaming at an almost screaming volume, but
it was insignificant amidst the sound of the washing machine.
"Teacher, experiment complete!"
Having completed those 20 vaginal length measurement experiments, I was already on the verge of ejaculation. I took the teacher's screams
as a pleasant accompaniment. I released her knees, squeezed my hands between her buttocks and the sheets,
tightly hugged her soft bottom, and then indulged in a memorable release deep inside her vagina.
This time, the target of my ejaculation wasn't her tongue, but the bottom of her alluring honeypot,
a forbidden territory that even the evil, perverted headmaster Jiang Wangcheng of the tutoring center had never conquered.
Finally, in the teacher's desperate eyes, she stopped struggling and resignedly let my penis
throb inside her vagina, filling the deepest part of her uterus with my semen. The washing machine outside the door also stopped running, leaving only
my heavy breathing and the teacher's soft "ha," "ha," "ha"
sounds.
I dared not linger too long in the afterglow of ejaculation. After all, this was just an "experiment," and I had to make the teacher
completely believe that I was only doing it out of a love of learning, and that all her transgressions were merely to cooperate with the elite teaching at the cram school
.
So I looked at my genitals, which had been tightly connected to the teacher just seconds before. My penis, having already ejaculated a large amount
, not only stopped trembling but had also returned to its harmless, cute pink shape. It
was then naturally squeezed out by the teacher's incredibly tight vagina due to its weakness.
As my penis slid out, a semi-transparent, white liquid trickled from the teacher's not-yet-fully-closed vaginal opening
. I knew it was a mixture of semen and the teacher's vaginal fluid.
Actually, my sexual satisfaction outweighed my thirst for knowledge, but I still pretended to be excited and shouted, "It really did get
thinner, teacher, I understand! Semen is the solute, and even though you don't have much secretion, adding your secretions
still lowers the concentration of semen!"
I said this on purpose to make the teacher think that she was still upholding the boundaries between teacher and student. So
what if the penis was inserted into her vagina? She didn't lose control because of it, and there wasn't much vaginal discharge. So what if she was ejaculated inside? The student's reaction was
the satisfaction of having the question answered, which was more gratifying than a physical orgasm. Besides,
is it wrong to satisfy students' academic and sexual needs at the same time? Would forbidding them from watching porn necessarily make them study obediently? It's better to
satisfy both their sexual and intellectual needs, saving them the time they would spend studying and masturbating at the same time!
"Thank you, teacher."
I took the initiative, forcing out tears as I knelt against
the chest of my teacher, who was almost unconscious with shame from being forced to ejaculate inside her.
"I thought physics and chemistry would be so hard, and I was going to be last in my class again in the second year of junior high. Thanks to you, sob
sob."
After ejaculating, I regained my saintly state, and was even more surprised by the evil I had after my erection. I ignored the teacher's resistance
and penetrated her, even boldly ejaculating inside her.
I took the teacher's hand, recalling the painful experiences of the past, and how that bastard Jiang Wangcheng
humiliated me every time after the monthly exam. I was really overwhelmed with emotions, and tears streamed down my face as I pretended to cry.
"Don't cry, congratulations on learning."
Teacher Li Zhenzhen picked up a tissue box, casually pulled out a few tissues and tucked them between her legs to prevent my semen from dripping
all over the sheets, and then thoughtfully wiped my pink little penis, which was covered with vaginal fluid and semen.
"Heh."
Seeing that the teacher didn't take the exaggerated after-school tutoring seriously at all, I decided to continue playing dumb, wanting to...
She then tried to tease me a bit more, reminding me of what we had just done.
"Teacher, why did you tell me not to ejaculate inside your vagina?"
I regretted asking as soon as I opened my mouth, because I had clearly learned in my first-year health education that ejaculation inside the vagina can lead to pregnancy!
Pretending not to know would only make my acting seem too exaggerated! "Because a woman's vagina is acidic, and a man's semen
is alkaline. The neutralization of acid and alkali will generate heat. If you're not mentally prepared, I'm afraid I might burn your glans."
Damn, I didn't expect her to give that answer. She must think I'm an idiot! But maybe she
didn't want to contaminate me. If she told me that ejaculation inside the vagina could lead to pregnancy, it might scare me, or it might make me associate her
teaching with male-female relationships. So she used such a strange reason to brush me off.
After she came to Bedford, she must have often heard other teachers mention the level of us students. And I
was indeed last in Bedford, so
it makes sense that she treated me like a slow learner, even enduring being ejaculated inside me without getting angry! Later, I wasn't too naive and quickly asked some difficult calculations
, which I learned very seriously, making the teacher feel that everything I did was out of genuine desire to do well in physics and chemistry.
After this experience of ejaculating inside the teacher, and the experience of having my semen admired during oral sex, I believe that
no one in the school understands aqueous solutions better than me! While the clothes were drying, the teacher took the opportunity to
take a shower. I also checked around to make sure that the teacher's boyfriend rarely came to her place. So
what if he's taller and more handsome than me, and even goes to a national university? They probably don't even have sex very often. Today, not only did I eat my girlfriend
, but I also ejaculated inside her. I'm so sorry, future teacher-in-law.
After the teacher finished showering, it was clear she was wearing a bra this time. Then she drove me back to the bridge to get my bicycle,
and I went home feeling incredibly happy, both physically and mentally.
(VII)
After ejaculating inside Teacher Li Zhenzhen, the closer it got to the time to go to the tutoring center, the stronger my sense of
guilt became. Tsk tsk, what was I thinking back then? I actually abused the teacher's sympathy and sense of responsibility towards me; if
I hadn't always been the last in the school's exams at Bede Tutoring Center, anyone else would
have been considered a pervert for making such a request to the teacher.
But I should be thankful that the teacher also said she would tutor me well. If my grades didn't improve,
I could ask the teacher for more help; if my grades improved, that would be even better, making the teacher think that
her teaching method was helpful to students, and I would enjoy endless bliss.
I nervously parked my bicycle and entered the Bede Tutoring Center building. Among the many receptionists and teachers,
I immediately spotted Teacher Li Zhenzhen's beautiful appearance. I politely greeted all the teachers and part-time students.
Teacher Li Zhenzhen responded without any apparent change in attitude. No one could have guessed that this brat, this "furnace master," had last night
inserted his still-developing penis into this young, beautiful teacher, and ejaculated inside her for the second
time in his life—an unforgivable and heinous crime.
With an hour before English class, I ate the lunchbox ordered by the tutoring center and then
studied in the common area. Teacher Li Zhenzhen proactively came over to tutor me, sitting directly in front of me. To help me understand the calculations
, she bent over and wrote numbers and symbols upside down so I could read them, completely unconcerned that this meant her
large breasts were almost completely exposed from her low-cut dress. Tang Chenwei immediately noticed this "perk" and leaned over
to listen with relish, actually just constantly adjusting his angle to fantasize about the teacher's breasts.
From the teacher's and my reactions, I knew she hadn't taken my almost prank-like physics and chemistry discussion from last night
to heart. I finally felt relieved and ran upstairs to my English class.
The following week in physics and chemistry class, the teacher's low-cut dress revealed almost two-thirds of her breasts.
While I was surprised, I couldn't help but worry about whether other students would take advantage of her. This was something I had declared I wanted,
and I had even left my scent inside her—how could someone else steal it from her?! I must
work even harder to protect her!
"This question had the most mistakes. Here, go to homework page 38, question 1: Which of the following substances has
the highest density? (a) 1 kg/dm3 (b) 7.8 g/cm3 (c) 0.5 kg/
m3 (d)" Teacher Li Zhenzhen reviewed the overwhelming amount of homework from last week. I knew that, except for a few people,
everyone else had copied it.
"I suggest that when learning new concepts, use association more often. Set a certain situation as a standard value, and then
compare everything with it to reinforce the concept. For example, a friend of mine who was studying criminal law
used a case study to illustrate each legal provision, which made the similarities and differences between the provisions very clear."
Teacher Li Zhenzhen professionally shared her learning experience. I secretly glanced back at Teacher Li and noticed that her smile had widened
. I didn't know if she understood something or was just mocking that such a professional teacher had to sacrifice her
looks to get the students' attention.
"dm actually means 'meter,' where 'd' represents one-tenth and 'm' is an abbreviation for meter. What
kind of length concept does this represent?" Teacher Li Zhenzhen guided the students to ask.
"Chen Jianian's little penis after erection," Huang Ruoli, sitting next to me, casually answered, and then the whole class
burst into laughter.
Damn, it really is! But I'm only in the second year of junior high school; I'll still develop!
"Yes, but 1 cubic inch isn't the concept of his penis; it's a whole mass about that size
, with a mass of 1 kilogram. What substance has a density close to 1 kg/dm3?" The teacher
gestured as he spoke, indicating the size of a cube with sides of about 10 centimeters.
I understood—it meant water! We're so used to
expressing the density of water in c. g. s. (cm, gram, second), but back then, the density unit was g/cm3, which is why we could say the density of water is 1. If
we switch to m. k. s. (meter, kilogram, second), the density of water becomes 1000
! And kg/dm3 and g/cm3 are the same unit! In other words, the order of magnitude in this problem
is b > a > c. We can't just look at which unit in the numerator or denominator is larger; we must actually convert the units.
Only then can we make comparisons; otherwise, as Teacher Li Zhenzhen said, we need to use actual objects as analogies.
Listening to the teacher explain unit conversions and international standard units, I recalled
the scene from last week where my standard unit expanded into the teacher's body and then shrank and slid out. I deeply felt that unit conversions were
so simple. The unit increases, the number decreases; the unit decreases, the number increases. The teacher's vaginal depth is currently
much longer than my penis, but when my standard unit increases, the teacher's vagina will almost be equal to my
length. And when I develop for another year and enter the third year of junior high, the teacher's vagina will almost be unable to accommodate my penis.
"So it's the teacher's breasts?" Chen Yuhao gestured towards the teacher's breasts, indicating
a size of about 10 centimeters cubic meters, while tilting his head in deep thought.
"Yes, the teacher's breasts are about 1 kg/dm3." After being instructed by Director Jiang Wangcheng last time
, Teacher Li Zhenzhen knew to make good use of her advantage. So, without any objection, she had the students gesture towards her breasts,
saying, "The density of the teacher's breasts is about the same as water, actually slightly less, but the teacher doesn't mind you using the teacher
's breasts as an analogy. Also, please remember the approximate concept of 7.8 g/cm3." Then, she
took out a weight in each hand.
"The weights we are using are made of stainless steel. Although they are not pure iron, their density is not much different from pure iron.
We know that substances with higher density will sink to the bottom of substances with lower density. Now, let's see if
the concept of density 7.8 g/cm3 is greater or less than 1 kg/dm3." As she spoke, the teacher lay back
on the first row of desks on the left. The first row on the right was for me and Huang Ruoli. The left side was usually where the teacher's belongings were placed, but
today the teacher had emptied it, apparently because she was going to lie down there.
The teacher alluringly presented her deep cleavage to the class, then
placed two weights, one on each side, on the exposed breast tissue above her bra. Sure enough, the weights, with a density of 7.8 g/cm3,
sank, pushing her exposed, white breasts further outwards and deforming them, proving that seemingly small units
actually have a density much greater than 1 kg/dm3.
I then noticed that the teacher was wearing a white demi-cup bra, so it only covered about a third of her
breasts. The simple cut, clinging tightly to her large breasts, appeared even more sensual. Although I had already
seen her naked body and private parts, and even
explored her vagina with my 10-centimeter penis, seeing this captivating scene still caused my crotch to tighten, and I immediately became erect again.
"But teacher, won't the force around your bra affect the pressure on your breasts? Wouldn't taking
off your bra make it more obvious that the density of the weights is much greater than the density of your breasts?" With Mom not in the classroom today, Tang
Chenwei was unusually active, offering a suggestion I could have predicted.
"Okay." After the headmaster and I "guided" her, the teacher seemed to have come to see selling her body as
merely a teaching aid. Plus, there hadn't been any whispers about her daring clothing or teaching style at the tutoring center lately
, so she increasingly accepted this teaching method as normal.
The teacher unceremoniously took off her bra, and from Tang Chenwei's angle, they could probably see her
pink nipples hidden under her dress.
"Can I experience the force of the weights on my breasts?" Tang Chenwei, unusually polite, raised his hand
to ask Teacher Li Zhenzhen.
"Anyone who wants to try can come and try. After all, when you drop a weight into pure water, you'll only see it sink
; you won't feel the force acting on it." The teacher finished speaking and lay back on the table expressionlessly, letting several
bold and lecherous students surround her.
The first was Zhen Shuzhu. Although she was a girl, she was quite curious about the feel of so-called large breasts, so she beat
Tang Chenwei to it, picked up a weight, and placed it on the teacher's chest, actually just wanting to get a clear look at a mature woman
's body.
The second was Huang Ruoli. Seeing Teacher Li Zhenzhen closing her eyes and having everyone compare
the density of the weights and breast tissue, he pretended to be conducting an experiment while simultaneously raising his legs and, when the teacher wasn't looking, swaying
his lower body as if the teacher were giving him a blowjob, his expression one of extreme ecstasy.
The most outrageous one was Tang Chenwei. Seeing the teacher's dress slipping lower and lower with the actions of the previous students
, he secretly tugged at the hem, causing her pink nipples to gradually slip out of the dress, eventually
becoming completely exposed!
Teacher Li Zhenzhen seemed oblivious to this subtle change, still accepting the students placing weights on
her chest with her eyes closed. So Tang Chenwei went further, gently placing both weights on her nipples
!
Metal has a high thermal conductivity, and heat is conducted from high to low temperatures. Therefore, in
an air-conditioned room at around 26 degrees Celsius, a person with a body temperature of 37 degrees Celsius will naturally and quickly transfer heat to the 26-degree weights
. Thus, the perceived temperature when in contact with metal is quite cold. If it were wood or cotton cloth, the perceived temperature
would not be so low.
The moment the metal weight touched her nipple, the teacher abruptly opened her eyes, discovering that the student had maliciously placed the weight
on her nipple. However, since Tang Chenwei was putting on a serious expression, and being the boss's child, she could only
pretend nothing had happened and continue lying down with her eyes closed. She couldn't stop her nipples from hardening from the stimulation, and
goosebumps rose around her small nipples.
Seeing that the teacher's pink and lovely nipples had turned into vibrant buds, the next group of boys followed suit,
each stimulating the teacher's nipples with weights. The teacher's tightly closed brows furrowed unnaturally, and her cheeks
gradually flushed.
Seeing the teacher's embarrassment, I was a little angry and wanted to go over and stop them, but as soon as I stood up, without indicating
whether I wanted to join their experiment or have any other purpose, Chen Yuhao glared at me fiercely and waved
for me to sit down. Remembering his idiot friends and their nasty behavior of smoking and fighting, I immediately
gave in and sat down.
During the process, I didn't expect Li Fa to join in. I thought she was a beautiful girl with a strong sense of justice,
but I didn't expect her to interfere too. From some angles, she was even worse than those perverts, because she actually stood on the table and used...
A free-fall experiment with weights! Luckily, the weights weren't very heavy, just very dense, otherwise the teacher's nipples
would definitely be bruised!
Huh? High density and heavyness are two different things. Mass per unit volume is called density, but the mass of an object itself
isn't necessarily related to density. It can only be said that for the same volume, the greater the density, the greater the mass. Li Fa, so you were
reminding me of this concept! It's really amazing, every move this crazy woman makes has a profound meaning.
Please allow me to call you Big Sister!
After the experiment, the teacher didn't have time to put her bra back on. She just pulled her dress up to make sure her nipples weren't exposed
before continuing the lesson. After all, in a place like Bedford, full of gifted students, the pressure to catch up on lessons is immense, and
time must be used wisely.
"Next, let's talk about the composition of air. Air is also a solution in a broad sense, with a very uniform molecular composition.
It consists of about 78% nitrogen, 21% oxygen, 0.9% inert gas argon, and the rest is water vapor and carbon
dioxide. Do you know what gas makes up the majority of the air we exhale?" Ms. Li Zhenzhen turned
around, her nipples faintly visible through her dress, and asked casually.
"Carbon dioxide." As a studious but academically weak junior high student, and also wanting to make a good impression in class
so I could step up in crucial moments later, I answered the question without raising my hand.
"Wrong. Nitrogen has very low reactivity. It only reacts with oxygen at high temperatures in the internal combustion engines of cars and motorcycles, causing
chemical smog pollution. So, at room temperature, the air we exhale is mainly nitrogen.
What's the second most abundant gas?" Ms. Li Zhenzhen continued.
Damn, I remembered! Even Tang Chenwei and the others were fooled by this question on their biology review test in the first year of junior high. I've
actually repeated the same mistake.
"Carbon dioxide." Hmph, surely I won't get it wrong this time.
"Still wrong. After a person breathes in the air, only a small
portion of oxygen is converted into carbon dioxide. About ten percent of the exhaled air is still oxygen; otherwise, what's the point of artificial respiration?
The gas we force-feed into the rescued person still contains a large amount of oxygen, with carbon dioxide
and water vapor being the third and fourth largest components; however, the exact order is still undetermined, as each scholar's experimental results are slightly different
." Teacher Li Zhenzhen finally began to demonstrate her professionalism. I believe Tang Chenwei and the others
would have a hard time finding the answers in reference books.
"By order of Mayor Ko Wen-je, every high school student will be required to learn CPR in the future. So, while explaining
the composition of air, we'll also practice. After all, the diversified admission process includes not only the high school entrance exam scores but also extracurricular
competitions, physical fitness, etc. Learning CPR
will definitely help you with competitions or obtaining certifications in the future. Xiaoping, come to the front and help." The teacher then asked me to go to the front of the class to assist her with the demonstration.
The teacher had me lie on the table, briefly explained the key points, and then pressed on my chest, demonstrating the pressing motion.
"Teacher, I think it would be more appropriate for you to play the role of Annie," Chen Yuhao and Tang Chenwei exchanged glances
, then said, "Everyone can easily find the area between Chen Jianian's breasts,
so there's nothing special to pay attention to when pressing. But for girls, especially those with prominent breasts like the teacher, shouldn't
the pressing position be calculated specifically?"
"Teacher, after the density comparison experiment just now, I think it's necessary to practice and see
the effect of the applied force on breast tissue," Tang Chenwei added, his eyes unusually sincere.
"Hmm." Oh no! Could it be that last week at the teacher's house I made up that Tang Chenwei and Chen Yuhao actually
enjoyed class, and the teacher really thought their "mischief" was just a different kind
of studiousness, like mine? She agreed without even considering it! I immediately lay down on the table, letting my braless breasts naturally
expand outwards.
"To fully understand the pressure on the chest, Apple's videos all feature models in bikinis demonstrating.
Could you show us your breasts to help us understand better, teacher?" Tang Chenwei asked.
"Okay." The teacher pulled down her dress, revealing two enormous
breasts that were still strikingly large even when lying down. She then closed her eyes, pretending to be unconscious and awaiting rescue.
"The line connecting the two breasts," Tang Chenwei seemed to be calculating precisely, gently stroking the teacher's nipples on both sides.
He finally calculated the midpoint of the line connecting the two nipples and placed his palm on it.
While Tang Chenwei pressed on the teacher's chest, his palm was indeed at the midpoint of the line connecting her breasts, but his
right hand below had his middle finger unnaturally protruding, the tip of which was touching the teacher's right nipple.
Each press resulted in him gently rubbing the teacher's nipple with his middle finger!
The mantra is supposed to be "press hard, press fast, breasts bounce back, don't stop," but Tang Chenwei's was basically "rub hard,
rub fast, nipples hard, get aroused!" Although Tang Chenwei pressed according to the teacher's instruction of 100 times per minute
, his fingers were actually faster than the vibrating egg!
Compared to her normal left nipple, Li Zhenzhen's firm right nipple stood out prominently.
Chen Yuhao and Huang Ruoli covered their mouths and chuckled, enjoying Tang Chenwei's manipulation of Li Zhenzhen
's upper body through CPR practice.
When it came to the artificial respiration segment, although I anticipated that the teacher would inevitably have to do mouth-to-mouth resuscitation with Tang Chenwei,
I still sat frozen in my seat, unsure how to stop it. Although my penis had been inside the teacher's mouth before,
and even her lower mouth, I had never kissed her lips. I really didn't want to see
that happen.
While I hesitated, Tang Chenwei's mouth was already covering the teacher's. The teacher, who had been keeping her eyes tightly closed
, suddenly opened them wide and struggled for a considerable amount of effort to push Tang Chenwei away.
"What are you doing!" the teacher exclaimed, wiping her mouth, which was covered in Tang Chenwei's saliva.
"Didn't you teach me that the higher the temperature, the lower the solubility of a gas? So I was moving my tongue around in your mouth, trying to
generate heat through friction to reduce the amount of gas dissolved in your saliva as much as possible, so that the person being rescued
could receive as much gas as possible," Tang Chenwei replied innocently.
Good grief, that's not entirely wrong. This was the first time I'd heard such an absurd explanation from Teacher Li Zhenzhen.
There was no way to refute it.
"Hmm, you're right." After saying that, the teacher lay back down, letting Tang Chenwei's tongue
swirl around in her mouth. He also lifted the teacher's beautiful face with his hands, ostensibly to clear the airway of the person being rescued,
but in reality, as I said before, he just wanted everyone to see his lewd appearance while French kissing the teacher, to prove
that he was an adult.
The teacher's skirt was not long today, and while Tang Chenwei was French kissing the teacher, Huang Ruoli stood
near the teacher's legs to admire the scenery under her skirt.
Suddenly, he seemed to notice something and called everyone over to look. I then noticed that the crotch of the teacher's underwear
was slightly wet with her own secretions. It turned out that the teacher could not resist the stimulation of her nipples and
the rough yet energetic and animalistic contact of her tongue.
"What are you doing!?" Suddenly, the classroom door was pushed open. I shifted my gaze from the teacher's crotch and
found that it was Sister Yu who came in, that is, Tang Chenwei's mother, the owner of the tutoring center.
"Oh, are you practicing CPR? Director Jiang Hong informed me that today's lesson might involve CPR practice
, so I came in to see if I needed any assistance. But teacher," she immediately noticed that the teacher was performing CPR with her breasts exposed
, pointing at the teacher's body and asking.
"It's easier to control the body's movements this way, and it's less likely that the bra underwire will pierce the lungs of the person being rescued,"
the teacher calmly replied, her mouth covered in the drool left by Yu Jie's good son.
"Hmm." Yu Jie thought for a moment, then asked, "Won't you be too slow by yourself? Do you need my
help?"
"Mom, we're done." In fact, only Tang Chenwei had practiced, but he immediately lied
to his mother.
"Chen Jianian, have you done it?" Yu Jie asked me. I wanted to follow Tang Chenwei's lead and say that I had also practiced
, but before I could answer, Li Fa immediately replied, "I haven't." "
Then I'll help. It'll be faster if both groups do it together. Chen Jianian, come here." After saying that, Yu Jie actually started to
unhook her bra.
"Mom, no need!" Tang Chenwei hadn't expected his mother to do
the same thing he'd just done to teacher Li Zhenzhen, so he hurriedly begged Yu Jie to stop.
"What does it matter? You've seen it before. Don't forget you were still bathing with your mother in sixth grade.
Besides, the teacher's teaching style is purely for educational purposes. You usually get 100 on tests, right? That proves
it's very effective. My former university professors also guided us in this way, which is how I got into the position
of school clerk." Yu Jie ignored her son's pleas and took off her shirt in front of the whole class, revealing
breasts that were no less impressive than teacher Li Zhenzhen's.
"Ke, I think you just want to compete with the teacher to see who has the better figure ." And through Sister Yu's words, it was confirmed
that Tang Chenwei consistently scored almost the same as Da Xiong in his tutoring class quizzes, yet always got perfect scores at school—clearly,
he was up to no good!
To be honest, aside from her darker, almost brownish nipples, Sister Yu's nipples were just as beautiful and elastic
as Teacher Li Zhenzhen, who was more than ten years younger than her!
Under Sister Yu's instructions, I was the first to go up. Given that she was the mother of the little tyrant Tang Chenwei, I
had to strain my eyes and carefully considered the strength of my hands, only doing so after Sister Yu corrected me several times
. I pressed hard on Yu-jie's chest, but my right middle finger wasn't as excessive as Tang Chenwei's, and I dared not
stick my tongue into Yu-jie's mouth.
I tried to avoid touching Yu-jie's breasts, but seeing her brown nipples near my palm, so
alluring and mature, so
different from Teacher Li Zhenzhen's young, large breasts and Li Fa's girlish breasts, I almost couldn't resist the urge to touch them!
I stared at Yu-jie's large breasts, wanting to put my mouth to them and suck on them a few times, partly out of physiological instinct,
this sexy body naturally... This made my crotch even harder, partly psychologically. If I could
possess this body, it would be the most humiliating way to retaliate against Tang Chenwei, who had bullied me for over a year!
Ha, but Teacher Li Zhenzhen was forced into it; she couldn't imagine why Sister Yu would go into the adult entertainment industry. It seems
my biggest act in this life is only this.
Next, when it was Li Fa's turn, she wasn't so polite. She completely imitated Tang Chenwei's actions in serving
Sister Yu. In just a few strokes, Sister Yu's nipples hardened, and she protested, panting, "Li Fa, what are you doing?"
"That's how Tang demonstrated the operation, isn't it?" Li Fa maintained her usual attitude,
expressionless and unhurriedly recounting the misdeeds of Sister Yu's son.
"Is that so?" Sister Yu glanced at Tang Chenwei but didn't seem angry. Half an hour later, the CPR
practice came to an end.
"We've finished Chapter 1, Introduction and Measurement, and Chapter 2, Water and Air. Now we're going to
go ahead and talk about the properties of sound and waves." After the last student finished their demonstration, the teacher pulled up her dress, but
still didn't put on her bra.
No wonder this is Bedford Gifted Academy; while everyone else is still on summer vacation, we've already covered the scope of our first midterm exam
.
"Waves are divided into mechanical waves and non-mechanical waves. The difference lies in whether or not a medium is needed for transmission. Can you all tell me
what kinds of waves we encounter in daily life, and also think about which waves require a medium, and what kind of medium?" The teacher continued
the lesson, while Sister Yu stood beside me wearing a shockingly large bra, completely oblivious to the greedy
gazes of the male students. "
Breast waves," I thought to myself, looking at Sister Yu's large breasts right next to me.
"Yijieye Duobo, Juice Honey Waves," Chen Yuhao blurted out, oblivious to the fact that the landlady was still in the classroom
.
"Don't think you can fool me just because I read AV actresses' names backwards. I do watch the 'Airline
Version'!" Teacher Li Zhenzhen retorted directly, perhaps wanting the shop owner to know that for teenagers' sometimes
inappropriate behavior, a little teasing and correction within acceptable boundaries, trying to be their mentor and friend,
is more effective than simply scolding them.
There's an AV video store near the cram school, its sign advertising "Airline Version."
Honestly, I didn't quite understand what it meant. It probably meant something like "exporting" or "selling abroad," hence the more explicit content.
Seeing Yu-jie's genuine smile, and her bold
act of exposing her breasts to assist with the lesson, I knew that Teacher Li Zhenzhen had made the right move. From now on, whatever she does in class, the boss's wife, the
major shareholder, will support her to the end. Thinking of this, I couldn't help but be happy for her.
"While mechanical waves require a medium, the medium doesn't move with the wave; it only
vibrates in place." As she spoke, the teacher gently poked her breasts a few times, and sure enough, her breasts rippled, but her fingers only moved in place.
"When the medium vibrates in place, it's called a 'wave.' If even the medium moves, it's called a 'wave'."
The teacher said, swinging her breasts from side to side, almost making my nose bleed. It really looked very "wavey."
"Waves are divided into transverse waves and longitudinal waves. The ripples on your breasts are transverse waves. Did you observe
the direction of your fingers?" Hmm, poking back and forth with her fingers, the breasts swaying left and right—very good, easy to understand indeed.
"If this were a classmate's finger, how would you define a transverse cut? How would you define a longitudinal cut?" The teacher
drew a rod-shaped object on the electronic whiteboard that didn't resemble a finger but was more like a penis, making everyone burst into laughter.
I immediately understood that cutting along the direction of the object is called a longitudinal cut, and cutting perpendicular to the object is called a transverse cut.
Therefore, a transverse wave is when the direction of the medium's vibration is perpendicular to the direction of the wave, like the teacher's breast waves, water waves, or rope waves, while a wave whose propagation
direction is parallel to the direction of the medium's vibration is called a longitudinal wave, such as a sound wave or a spring compression wave.
"A complete mechanical wave must contain a complete waveform, that is, a crest and a trough." After saying
this, the teacher lay back on the desk, and I then realized why she wasn't wearing a bra.
"When you encounter a test question, you usually won't be given a complete waveform to judge. Sometimes you have to use the wave crest to crest,
and sometimes you have to use the trough to trough." The teacher lay on her back, letting the students admire her naturally large
breasts from the side, while pointing to her nipples with her index fingers. " Hmm, indeed, the waves connect to the horizon. A complete
breast is a wave, the wave from nipple to nipple crest to crest is another wave, and the wave from armpit to cleavage trough to trough
is yet another wave.
"And the time it takes for a complete wave to occur is called a cycle; conversely, the number of waves generated within a unit of time
is called frequency." And so on and so forth, this part is a bit difficult to understand.
"When you were doing CPR just now, 100 times per minute, that's the concept of frequency. Come on, Tang Chenwei, please
replay how you just played with the teacher's nipples." Tang Chenwei glanced at Sister Yu standing by the door, seemingly
not intending to move forward.
"Go on, how did you just do it?" Sister Yu mockingly urged him to hurry up.
After Sister Yu witnessed it firsthand and Li Fa's intentional or unintentional tattling, Tang Chenwei knew that a family revolution
was about to unfold when he got home. This was actually just a piece of cake, so he recklessly walked to the teacher lying down and
quickly teased her nipples with his fingers, instantly making her nipples, which had finally subsided, harden again.
"That was about 10 times per second. We specifically shorten 'number of times per second' to 'hertz,'
meaning Tang Chenwei's fingertip frequency was 10 hertz, abbreviated as 10 Hz." The teacher didn't even look up
, suppressing the pleasure in her chest, and continued speaking fluently. I think the level of professionalism she displayed in this class made
these little brats admire her.
"Don't go so fast this time. Please use a frequency of 2 Hz to forcefully poke the teacher's nipple. Xiaoping, please time it
and tell the teacher after ten seconds." Damn, are you a masochist? Why do you have to make students poke your nipples so hard?
"Xiaoping!?" This time, not only did Li Fa have a strange reaction, but even Sister Yu's body suddenly trembled.
"It's me. Chen Jianian's 'Nian' was written too ugly, so the teacher called me 'Xiaoping.'" I explained to Sister Yu that
"Xiaoping" was actually referring to me.
"I thought it was Sister Yu's college classmate." Sister Yu laughed.
Following the teacher's instructions, Tang Chenwei poked the teacher's nipples 20 times, creating
ripples on her chest.
"The diameter of one of my breasts is about 20 centimeters. Have you noticed
how long a complete wave of my breast is?" The teacher stood up, pressing her breasts together to prove that
the diameter was indeed around 20 centimeters. However, without pressure, the diameter was less impressive, only about 12
to 15 centimeters. "How
far my breast wave travels in one second depends on the wavelength of my breast and the frequency at that moment. Multiplying the wavelength
by the frequency gives you the wave speed—it's a very simple principle. Conversely, you learned in elementary school that
speed is calculated by dividing distance by time. Wave speed can also be calculated by dividing the length of a wave by the time it takes for the
wave to occur, which is wavelength divided by period. Therefore, frequency and period are reciprocals." The teacher
excitedly finished this explanation, her breasts jiggling. However, Huang Ruoli and I, although sitting in the first row and feeling
the most intense breast jiggling, didn't understand a word.
Seeing my bewildered look, Teacher Li Zhenzhen lay back down on the table: "This time, use a frequency of 5 Hz per second!
Time it for 10 seconds!"
Tang Chenwei had just been teasing the teacher's nipples with his fingertips during CPR, easily reaching 10 Hz. Now, he
was poking the teacher's chest heavily with his index finger. Although he enjoyed it, he knew it wasn't easy, and
he completed 50 pokes with trepidation.
"Everyone can clearly see that after the frequency increases, the length of a complete waveform on the teacher's chest decreases
, that is, the wavelength becomes shorter. However, the rate at which the wave propagates through the teacher's chest does not change significantly, which is enough to prove
that in the same type and property of medium, the wave speed does not change!" The teacher explained while poking her own
chest, changing the frequency from time to time to prove that what she said was true. Increasing the frequency only shortens the period; increasing the frequency
also only shortens the wavelength. Therefore, wavelength and period are directly proportional, calculated by dividing by the same side of the equation. Conversely,
frequency and wavelength are inversely proportional, calculated by multiplying by the same side of the equation, resulting in a constant product. I've finally understood another
complex concept!
"As for amplitude, it refers to the extent to which the medium vibrates off its equilibrium position. It has nothing to do with frequency.
A wave with a higher frequency can have a larger amplitude, and vice versa," the teacher said, speaking at a high frequency and with great force.
She poked her own chest, repeatedly and subtly poking it to demonstrate that her idea was correct.
"It's just like what Chenwei usually does in the room. At first, he stimulates the tip with a high frequency and small amplitude,
then later he starts stroking from the base with a small frequency and large cycle, proving that amplitude and frequency are unrelated." Sister Yu
revealed this pointedly, but I didn't understand what she was talking about.
"Mom!" Tang Chenwei stood up in fright upon hearing this, shouting to interrupt Sister Yu.
"Sigh, don't think adults don't know what you kids do. Who wasn't a brat when they were young
? Teacher Li, these kids will spend time watching inappropriate things at home anyway, so why not have a teacher
make learning fun and educational, allowing them to release their excess energy while learning, and stop
wasting time searching for information about the body's structure? From now on, they're in your hands. I won't interfere with the teaching methods at all, and I
'll put in a good word for you with the shareholders." After saying this, Sister Yu gave Tang Chenwei a loving smile and continued, "If you're embarrassed,
Mom won't bother you here. You should try your best to attend class. As long as the teacher is willing to cooperate, you don't need
to worry about anything. Mommy is going home to prepare your favorite bird's nest soup."
Hearing the teacher's masterful explanation throughout the lesson, Sister Yu had essentially given Teacher Li Zhenzhen a free pass
! She just wondered if this meant the teacher would stop providing shabis (a type of sweet soup) in the future?
Watching Yu-jie actually walk out of the classroom, Tang Chenwei was still standing there, forgetting to sit down. The teacher then walked over and
said gently, "I know you're all curious about sex during puberty.
How about we learn together and answer these questions, like Yu-jie suggested?"
Seriously, these kids don't need you to explain things to them.
I'm the only one in the class innocent enough to need guidance!
I was secretly laughing at Teacher Li Zhenzhen's naiveté when she moved closer to Tang Chenwei and whispered,
"Yu-jie just said something about what you usually do. Can you show me what you do?" She leaned forward,
pleading with Tang Chenwei in an almost begging tone.
Seeing the teacher's large breasts hanging like bells because she wasn't wearing a bra, Tang Chenwei stubbornly said, "But I haven't
gotten hard yet." "
Then what do you need to do to get hard?" the teacher asked, pouting.
"Boys are visual creatures, teacher, show me over there." Tang Chenwei, unlike his usual mischievous self,
stared blankly at the teacher's skirt. "Have you ever seen a girl's side?" The teacher turned to the side, legs pressed together,
and asked Tang Chenwei.
"Never seen one in person." Tang Chenwei swallowed hard.
Damn it, all those rumors about sleeping with some slut from another school, or messing around with some delinquent girl,
were all lies! He's a virgin! Thinking about it this way, maybe even Chen Yuhao
was just talking nonsense, and I'm the only one in the class who's lost my virginity! I'm the real devil in this class!?
Just as I was amazed by Tang Chenwei's innocence, I realized that my act of pretending to be a fool and then ejaculating inside Teacher Li Zhenzhen was the truly
heinous crime, and I was overwhelmed with shame.
While I was still in a daze, Ms. Li Zhenzhen had already taken off her underwear, which was already soaked with her own sweat. She then
sat in an empty seat in the last row, spread her long, straight legs (a full 110.3 centimeters long) to the side, and
leaned back slightly to expose her genitals. She then explained to Tang Chenwei, "This is the clitoris." She then
touched the small bean at the lower edge of her pubic hair and pulled back the foreskin to show us her glistening clitoris.
Li Fa, sitting next to Tang Chenwei, still had a smile on her face, but she was clearly very interested in the scene before her,
staring wide-eyed and even taking notes!
"The part next to the inner thigh is the labia majora, and the two petals in the middle are the labia minora."
Although Ms. Li Zhenzhen couldn't see her own genitals, she easily pointed out the exact locations based on her more than twenty years of familiarity,
just as Director Jiang Wangcheng had taught her last week—it was essential to be familiar with the course content and with one's own body.
"The opening at the top is the urethra, and the one below is the vaginal opening." The teacher skillfully peeled back the pink structure,
pointing to her most shameful and embarrassing part. Although I knew she had adjusted her mindset,
her cheeks still flushed at such a bold action.
The whole class was so quiet that everyone could hear their own breathing. Even Zhen Shuzhu and Chen Yuhao stopped acting strangely and
just obediently stared at the private parts of this woman who was actually a sexy older sister, despite being a tutor. Boys
naturally love to look, and girls are curious about their own anatomy, which they often can't see in its entirety. Now that there's a real person to let
them know, it seems pretty good, and they all watched with great interest.
"Are you hard?" Teacher Li Zhenzhen didn't dare to look at Tang Chenwei, turning her face away shyly and uttering
these words.
"Yes." Tang Chenwei nodded excitedly, his eyes red.
"Then can you take out your platinum-iridium alloy rod and make low-frequency friction?" The teacher suppressed her laughter and shame,
saying a sentence that sounded like something you'd hear in a physics or chemistry class. But after Yu-jie's revelation, we now all
know what that sentence means.
Tang Chenwei, who usually enjoys teasing me and always shows disgust and ridicule when he sees me with my penis exposed, couldn't resist the teacher's temptation any longer . He simply unzipped his suit pants and pulled out 　　a dark-colored penis that was longer and darker
than mine from his already bulging crotch ! 　　"Can you demonstrate the low frequency for everyone?" the teacher instructed shyly. 　　Tang Chenwei gripped the tip of his penis tightly and slowly rubbed it. So this is what masturbation is like. I finally saw it for myself 　　. 　　"Other students can come over too. Let's play a game. The teacher will give the instructions. If you make a mistake, you have to 　　pause for 30 seconds." The teacher finally overcame her shame and turned around to call everyone to her from the back of the classroom. 　　In less than a minute, she was surrounded by male students with exposed penises and bewildered female students 　　. None of the male students' penises, including mine, were limp. Every single one, regardless of size, was erect and proud. 　　"In a moment, follow the teacher's instructions to perform the actions. Each incorrect answer will result in a 30-second pause. 　　The three people with the most incorrect answers will need to come to Director Jiang Hong for tutoring on Saturday." Damn, tutoring by Jiang Wangcheng? No way! Lin 　　Bei is determined to win!

"Girls can do it too. If you're shy, you can
just use your fingers to gently make the movements through your skirt or pants." The teacher was as kind as a big sister next door, corrupting these probably still innocent girls.
"Let's begin. Everyone, start with low frequency and low amplitude movements." The teacher still had her legs spread, her genitals facing
us, but now she couldn't be shy anymore, because she needed to clearly identify the students who made mistakes. A good teacher
must be fair in rewards and punishments; regardless of how strict they are, fairness is the most basic requirement!
I've never masturbated, but biological instinct made me grasp the tip of my penis. I fantasized about having another chance
to enter Teacher Li Zhenzhen's body, so I gently stroked the foreskin back and forth, occasionally revealing half of the glans.
"High frequency, low amplitude!" I recalled what the teacher had taught and sped up the stroking motion, but still
didn't fully expose the glans. After all, a small amplitude movement is called low amplitude. Most of the male students knew how to masturbate, and those who didn't 　　had been taught
by Tang Chenwei during their year at Bedford . Some of the female students, however, couldn't let go of their inhibitions. They were usually very fond of making lewd jokes, but now they 　　didn't know how to do it. 　　The teacher, somewhat leniently, prompted the girls who hadn't yet started, quickly and subtly rubbing her clitoris 　　. This finally got the girls to follow suit, even the usually extremely pretentious Zhen Shuzhu 　　. 　　Although the teacher said she would catch three, we had no interest in watching whether others were doing it correctly; we were too busy admiring 　　the teacher's seductive charm. Every male student was staring intently at the teacher's vulva and lips, afraid of making a mistake 　　and having to stop masturbating for 30 seconds. 　　I glanced at Li Fa and realized that this guy was indeed an idiot in some ways. While most girls 　　follow the teacher's instructions, what teenage girl doesn't 　　protect her body tightly? At most, they might rub their clitoris through their underwear, not revealing a single bit of their genitals to avoid being 　　taken advantage of by boys. You've taken your pants off again, what's wrong with you?! 　　Li Fa was completely naked from the waist down, only wearing a thin pink shirt on her upper body. Although she still had that silly, 　　half-smiling face, her face was flushed from the high-frequency rubbing of her clitoris with fingers, and her big eyes 　　were filled with desire, almost making a sound. 　　I didn't know whether to look at the teacher or Li Fa. Suddenly, the teacher shouted, "Large period, large amplitude!" I 　　continued to vigorously rub my penis at a high frequency. Immediately, I heard the teacher say, "Xiaoping, stop rubbing for 30 seconds!" 　　Waaah, period and frequency are reciprocals. Large period means a long time interval, so everyone else 　　correctly slid from the base of the penis to the glans to achieve the effect of increasing both period and amplitude simultaneously. 　　"High frequency, high amplitude!" Everyone was happiest when they heard this. All the boys vigorously and quickly rubbed 　　their little penises. I almost let my penis naturally break free from the foreskin. Except for 　　the time when the teacher gave me oral sex and when I forced my penis into the teacher's vagina, my glans had never been fully exposed. 　　"High frequency, small wavelength!" Three three three small? 　　"Xiaoping, wrong answer!" Not understanding for a moment, I had to stop rubbing for 30 seconds again. 　　During my break from masturbation, watching Huang Ruoli's rapid masturbation, which actually tightened the folds of his foreskin, I realized 　　that within the same medium, since the wave velocity is constant (equal to the product of frequency and wavelength), a higher frequency 　　naturally results in a shorter wavelength. 　　"Large period, large amplitude!" Having already witnessed Huang Ruoli's premature ejaculation in the second physics and chemistry class, he indeed 　　couldn't last more than a few rounds. The teacher had already switched from high frequency to large period, but he still couldn't bear to stop 　　, forcing semen to gush from his urethra. 　　"Huang Ruoli answered incorrectly!" the sharp-eyed teacher shouted. Actually, I knew he hadn't answered incorrectly; he was just about to 　　ejaculate, and the teacher suddenly wanted him to lower the frequency, which he couldn't bear, so he ejaculated while simultaneously receiving a "bad grade." 　　"Teacher, where should I ejaculate? The student workers will be angry if you get the floor dirty." Tang Chenwei 　　asked, suppressing his urge to ejaculate, but his hands didn't neglect to change the frequency and amplitude according to the teacher's instructions. 　　"Aim at the most natural target." The teacher said shyly. 　　"Okay." Tang Chenwei said, about to ejaculate on the ground. 　　"No, isn't the purpose of semen production to be ejaculated into the vagina? Aim at me." Hearing this 　　, both boys and girls stirred. This beautiful female teacher was actually telling the 　　male students, most of whom were still virgins, to ejaculate into their vaginas! Hearing this instruction, several girls, who had been rubbing their clitoris for a long time 　　and were surrounded by penises of various sizes, actually clenched their legs and reached clitoral orgasm! 　　After hearing the teacher's words, Tang Chenwei held his penis and brought the head of his penis close to the teacher's pink opening, immediately 　　wanting to push the head of his penis into the teacher's vagina. 　　"No, no!" The teacher glanced at me, as if recalling the scene of me ejaculating inside her that day. 　　"Didn't you all learn the Pythagorean theorem in math? Then 　　review it with the trigonometric formula song by internet celebrity teacher Liu Jing, and make sure you're at least a meter away before you ejaculate." The teacher covered her 　　vagina with her right hand, which was almost penetrated by a student, while gesturing for Tang Chenwei to back away. 　　"Damn, I shouldn't have ejaculated so quickly." Even if he couldn't actually ejaculate inside the teacher's vagina, it 　　was still very stimulating to spray semen on the teacher's vulva. Huang Ruoli rubbed his already swollen penis, hoping to 　　regain his vigor. 　　Unfortunately, Tang Chenwei didn't even have a chance to adjust his angle. Just as the teacher told him to back away, he couldn't help but 　　ejaculate first, spraying semen onto the outside of the teacher's right palm at close range, with the rest spilling on the ground. 　　Two or three other students had mistakenly thought the teacher was going to let them ejaculate inside her vagina and were so excited that 　　they ejaculated before the teacher even finished speaking, their trembling penises groaning in frustration. 　　Seeing that no students had crossed the line, the teacher bent her legs and sat on the table with her buttocks raised. Then 　　she leaned back, exposing her genitals not only completely but also upwards, allowing us to see her anatomy more clearly! 　　The teacher then spread her hands apart from the inside of her thighs, so that her palms were between her legs. 　　She then used her fingers to pry open her thighs near her genitals, revealing a pink, moist, 　　and already soaking wet, sticky vulva!

Seeing the beautiful teacher who had just been talking about fluctuations on stage, now spreading her legs like a wanton woman, waiting to be filled with semen
, this extremely lewd scene immediately sent Chen Yuhao's lust soaring to its peak. He adjusted
the angle of his penis, singing Liu Jing's trigonometric function song: "Sperm, flies out from the hypotenuse, pants,
fall off from the hypotenuse." Wait, isn't it sin flies out from the hypotenuse and cos falls off from the hypotenuse? Sigh, forcing growth,
memorizing trigonometric functions in junior high school resulted in this kind of haphazard memorization.
I watched Chen Yuhao's semen spurt out with trepidation, fearing he would ejaculate and actually spray it into the teacher's vagina
. Although the chances of the teacher getting pregnant from this were extremely low, Lin Bei was still going to give it to her!
Fortunately, this guy even sang the trigonometric function song wrong, so of course he couldn't spray very accurately. He accidentally sprayed it on Zhen
Shuzhu's shoes and got a few light punches.
I rubbed my penis harder, determined to be the first to ejaculate on the teacher; my sperm would never lag behind!
So, on the verge of climax, I stood on Tang Chenwei's desk, aimed at the teacher's vaginal opening, and fired, hoping her
tender hole would be covered in my scent from the inside out!
Although my grades at Bedford were as terrible as Nobita's, my shooting skills were just as outstanding
. I easily sprayed my semen onto the teacher's pubic hair and vagina. As if encouraging me, the teacher
forcefully spread her vaginal opening, making the pink folds of her vagina clearly visible. Then, my white, cloudy
semen naturally flowed in like it was being subjected to an antlion's hell.
Hehe, the teacher's vagina and my penis were indeed a match made in heaven; neither of us managed to ejaculate successfully, only
I succeeded, and the teacher even deliberately let my semen flow to her deepest point!
Seeing this, several more male and female students climaxed. The male students tried to imitate my angle, but
they couldn't even adjust before they lost control and ejaculated all over the floor.
"Hmph, these young bastards," I thought, taking out a tissue to wipe my glans. After all, the last few twitches of my urethra couldn't produce
the same powerful ejaculation as at the beginning, and some had dripped down.
I looked down and took out a tissue from my pocket, only to find a beautiful face looking up at me with a cold smile!
Damn it! I dripped semen on Li Fa's head!
Wanting to stand at a higher position, I naturally stood at Tang Chenwei's table. At the time, blinded by lust
, I didn't pay any attention to Tang Chenwei, nor did I realize that it was also the table of the perverted beauty Li Fa
!
Li Fa looked at my penis, which was curled up in a ball because I had just ejaculated and was actually afraid of her crushing kick,
and surprisingly showed an angry expression. However, she didn't harm me; she just stood aside wiping the semen from her hair
.
In the end, all those left to attend Saturday tutoring were boys, including me and two other guys who weren't as
assertive as Tang Chenwei and his friends, but still liked to bully me. I hope Ms. Li Zhenzhen won't be too nice to them. I don't
mind doing exercises all day, but I don't want any sabbaticals!
