(08) In the last physics and chemistry class, Tang Chenwei was surprisingly "well-behaved". It seemed that his mother appeared in class and not only was her breasts exposed by the classmates, but some classmates also took the opportunity to play with his super big breasts of F cup under the guise of CPR practice; on the other hand, it was because he confessed to Li Zhenzhen in a gentle tone that he had never seen a girl's genitals in person, which was equivalent to indirectly admitting that his previous boasts about his good performance in bed were just lies. I thought he would restrain himself a bit, but I didn't expect to hear his words in math class, which made me worry about Li Zhenzhen's chastity again. "What? I'm a virgin? Please, how can I have a chance to sleep with the teacher if I don't say that?" When Tang Chenwei faced the ridicule of his best friends Chen Yuhao and Huang Ruoli after class, he lewdly said his desire for the teacher, and pretended that the premature ejaculation from masturbating in class that day had never happened. Even though the tide has receded and his pants have been washed away, he's still stubbornly refusing to admit it. He couldn't even last two minutes masturbating in front of the teacher's crotch, yet he dares to claim he's sexually proficient. If I weren't so cowardly, but instead had a bunch of idiot friends like Chen Yuhao, seeing him so utterly exposed yet still desperately denying it, I would have slapped him long ago! It's almost time for our week's physics and chemistry class, and today the teacher is dressed in a very revealing low-cut top, slightly showing the top of her green bra. Her ethnic-style floral long skirt looks quite dignified, but upon closer inspection, it's practically see-through; if she bends over, her pinkish-green underwear is clearly visible! She wasn't dressed like this near the counter just now! She must have changed specifically for our class, otherwise, the parents would have complained long ago. The teacher turned on the interactive whiteboard as soon as she came in, continuing the lesson on the concept of vibrations from last week. I glanced at Li Fa; her half-smile turned sour when she saw me. Haha, this meant she had temporarily lowered her guard. After all, we were already good friends who had seen each other's bodies. Very good. "The generation of a sound wave requires an object to vibrate rapidly in a medium, and one vibration contains four amplitudes." The teacher drew a diagram of a particle vibrating continuously up and down on the whiteboard and played a Flash
animation to help us understand. Even someone as brain-dead as me could understand it, so I didn't believe anyone else wouldn't. "Teacher, is this what four amplitudes mean?" Chen Yuhao clenched his fist and made the mischievous gestures that boys usually do in their rooms, gesturing up and down. "Yes, the movement from the equilibrium point upwards to the highest point, then downwards back to the equilibrium point, then downwards to the lowest point, and then back to the equilibrium point completes one wave; conversely, it can be from the equilibrium point to the lowest point, or even from the highest or lowest point, as long as the vibration of the medium passes through four amplitudes." The teacher fluently explained the process of a complete wave, while simultaneously making up-and-down movements with her palms on the classroom floor. She looked gentle and charming, completely different from the lewd actions of Chen Yuhao. I originally thought that Chen Yuhao was going to pretend to be innocent and continue to try to get more benefits from the teacher, but unexpectedly, the teacher walked over herself and casually placed her palm on Chen Yuhao's crotch. Chen Yuhao didn't expect things to happen so suddenly, and instinctively shrank back a little, then stood still, his eyes shining as he wanted to see what the teacher would do next. Although Ms. Li Zhenzhen didn't want people to question her professionalism, taking off one's own pants and taking off someone else's pants are completely different concepts. She still put in some effort to remove Chen Yuhao's outer pants, then his underwear, revealing his still-soft penis. "In terms of your masturbation movements, a complete vibration, if you take the mid-section of the penis as the balance point, is starting from the penis, moving forward to the glans, then back to the mid-section, then sliding to the base, and then returning to the mid-section." The teacher casually picked up Chen Yuhao's penis, which wasn't much bigger than mine, and moved it back and forth. "Teacher, sorry, I can't see very clearly. Could you please make it bigger first?" Chen Yuhao glanced at Ms. Li Zhenzhen, who was squatting on the ground explaining, and asked. Damn it, isn't that your own penis? You can't even see it clearly! I think the teacher should just casually rub it a few times to get it erect; there's no need to be too nice to him. Looking back on the lessons so far, the teacher has only given me oral sex in class, and even had her vagina penetrated by my penis in private. Not to mention, I've ejaculated into her vagina in front of the whole class. She belongs to me, and the teacher should respect her position. She wouldn't do anything too outrageous, right? "Hmm." After saying that, the teacher unhesitatingly stuck out her tongue and skillfully licked Chen Yuhao's glans. It was like a bolt from the blue! What? I thought those sabis that belonged only to me were taken away in the blink of an eye! The teacher's soft tongue was actually licking the dirty outlet from which a brat ejaculates semen and urine every day, not to mention that dirty opening belonged to a scoundrel who had bullied me for years! ? Thinking about it, it's not too surprising. After all, even a teacher like me, a master of the furnace, is willing to sacrifice my body to guide. In terms of return on investment, those high-achieving students have more reason to possess the teacher's body. Besides, the landlady, Sister Yu, said last week that as long as the teacher doesn't mind, she won't interfere with the teaching method at all. She even hopes that the teacher can let them achieve multiple goals in class, such as learning physics and chemistry, satisfying their curiosity about the opposite sex, releasing excess energy, and saving time for watching porn at home. In that case, it's only a matter of time before the teacher's vagina is violated by other beasts. However, I still can't get over it. I used to be at the bottom of my class, and after finally getting into the second year of junior high school, I managed to be the first to get oral sex from the teacher. I even secretly slept with the teacher under the guise of tutoring, losing my virginity in a cool way, and achieving the achievement of being the only one to ejaculate inside the teacher's vagina. All of these feelings of superiority have vanished, replaced by a greater sense of humiliation than before, especially when I see the dazed look in the teacher's eyes. The teacher, eyes squinting, licked Chen Yuhao's penis, sometimes taking it into her mouth, sometimes just sticking out her tongue and licking it quickly. She stretched her tongue as far as she could, like an AV actress, Shizuka Kanno. This teacher was no longer the beautiful, gentle, and kind Li Zhenzhen of the past; she resembled the succubus Sajupa from Greek mythology! Finally, this painful ordeal didn't last long, and Chen Yuhao's penis became erect. The teacher stopped demonstrating with her hands and instead had Chen Yuhao stand on the table. She then stood on a chair, slightly crouching, adjusting the height difference, and began to perform the so-called "complete vibration" with her mouth. "Look carefully, now the teacher's mouth starts from the tip of Chen Yuhao's glans. When you finish one vibration, please shout 'Stop!' so the teacher knows if you've learned it." The teacher, having finally stopped, lightly touched the area near Chen Yuhao's urethral opening with her lips. Then, with her sexy, bright red lips slightly parted, she slowly took Chen Yuhao's approximately 12-centimeter-long penis into her mouth, inch by inch, until her lips were tightly pressed against Chen Yuhao's pubic hair, leaving only his testicles exposed. I wondered if the teacher's throat was that long? She effortlessly kept Chen Yuhao's entire hard penis in her mouth. Then, the teacher paused for a moment, making sure no one thought this was a complete vibration, before slowly spitting out Chen Yuhao's penis inch by inch, revealing his ugly, lewd penis, now wet with the teacher's saliva. "Stop!" The classmates shouted the order to stop in unison. I yelled "Stop!" especially loudly. By this point, I understood what "one vibration, four amplitudes" meant. Please, don't continue; it will hurt my young and innocent heart. "Next, we'll start from different parts. Students, shout 'Stop' after completing one vibration." The teacher's mouth was full of saliva and Chen Yuhao's disgusting urine stains, making his words indistinct. Then the teacher put his mouth on Chen Yuhao's penis again, but this time he swallowed half of it, then started backing away until Chen Yuhao's penis was fully exposed, then he swallowed the whole thing, then backed away again…
"Stop!" Huh? The deafening shouts from the whole class jolted me awake. I realized I'd been so focused on the teacher's oral sex that I hadn't noticed she'd already finished one vibration. I suddenly felt a pang of sadness, almost to the point of tears. If it hadn't been the whole class answering at once, and only I had, wouldn't Chen Yuhao have gotten a good deal from the teacher for a while longer? And here I was, talking about protecting the teacher's body, but what a fool I was, I hadn't helped her at all. With tears in my eyes, I continued watching the scene of the physics and chemistry teacher giving oral sex to the gang leader. Li Fa glanced at me, a slightly empathetic expression on her face. I nodded and smiled slightly at her, thanking her for her empathy. However, she was a woman of few words in class. Although she'd joined in the clitoral stimulation last time, she'd rarely spoken, and today she hadn't said a word when she should have called for a stop. This time, the teacher started from the base, immediately having Chen Yuhao's entire penis fill her mouth. Then she gradually withdrew, advancing only after the entire penis was exposed, until Chen Yuhao's penis was pressing against the teacher's throat again. However, this time, apart from me choking back tears and quietly calling for a stop, the whole class surprisingly kept their mouths shut. Even though this was considered a cycle after it was fully inserted, no one in the class called for a stop. Teacher Li Zhenzhen thought it wasn't inserted enough, so she frowned and forced her mouth closer to the base of Chen Yuhao's penis until she realized her lips couldn't go any further, and her uvula was being pushed against the glans until tears streamed down her face. Only then did she allow the penis to withdraw slightly from her mouth. Teacher Li Zhenzhen knew that her classmates were teasing her, so she deliberately didn't call for a stop. However, in order to maintain a good atmosphere with the class, she pretended not to know and continued to perform oral sex on Chen Yuhao with great effort, repeatedly making "pop pop pop" sounds as Chen Yuhao's glans thrust in and out of her lips. I don't think it was more than ten cycles already! "Stop, stop, stop!" I shouted stupidly, trying to interrupt this scene that was obviously quite interesting to others. Teacher Li Zhenzhen heard my voice and finally made a "pop" sound as Chen Yuhao's swollen and purple glans left her lips. "Now you finally understand what a complete vibration, a cycle, and four amplitudes mean, right?" Teacher Li Zhenzhen wiped her mouth smugly. After all, she had demonstrated these easily confused concepts perfectly through her body. Apart from the moralists who might have some objections, students everywhere had to admire her dedication and professionalism. Not to mention that time when the whole class ganged up to tease her, she neither got angry nor panicked. On that point alone, even I had to admire her, even though I still felt a little sad because she had performed oral sex on someone else. "Teacher, we didn't see it here." Huang Ruoli suddenly attacked at this moment. Please, the teacher has been sucking for so long and you're only saying you didn't see it now? You son of a bitch! "Okay, this time I won't let you stop. I'll demonstrate each posture twice consecutively, starting from the highest point, the lowest point, and the balance point. Can those of you who didn't see it watch carefully?" The teacher had indeed overlooked the students in my position, and because I didn't want to look too closely, I hadn't noticed. I knew Huang Ruoli was using this as an excuse, but the teacher should have tried to prevent her from finding fault. "Hmm..." So, while giving Chen Yuhao oral sex, making his penis move in and out of her mouth, the teacher also had to keep an eye on the students in my position, making a "1, 2, 3, 4, 2, 2, 3, 4..."
gesture to indicate that one vibration required four amplitudes. While the teacher was looking at Huang Ruoli seductively, Chen Yuhao glanced at Huang Ruoli in approval, then closed his eyes and enjoyed the teacher's service. Teacher, look, they're all in cahoots! They're not as eager to learn as I am; they just want to bully you! "Is that enough?" After the last swallow, the teacher gently pulled the glans away from her lips with a "pop," wiped her mouth, and asked. Whether from exhaustion or arousal, her cheeks flushed, and the constant stimulation of the penis on her throat caused tears to well up in her eyes. Chen Yuhao, somewhat dejected, pulled up his pants. "Teacher, you can't see from here either." Damn, which crazy woman was talking nonsense? But I immediately recognized the source of the voice—it was Li Fa!? I thought we were on the same side, why…you!? "Okay, any other students who haven't seen it, please come over here, okay? We've been delayed in our lesson." The teacher then continued to half-squat in front of Chen Yuhao. Chen Yuhao thought this perk was over, but Li Fa had unexpectedly secured another round for him. He happily winked at Li Fa, but Li Fa completely ignored him. Damn Li Fa, you stinky Li Fa, when you grow up you should go work at a "pure" hair salon as a hostess, so you can cut hair to your heart's content, damn it! So, Teacher Li Zhenzhen once again took Chen Yuhao's glans, which was frighteningly large compared to its pre-erection size, into her mouth and began to swallow and spit it out repeatedly. Although I didn't want to see this horrific scene, I still hoped that more people watching would scare Chen Yuhao into losing his erection, so I also crowded around to watch the teacher's oral sex demonstration up close. Oh no, even the student with the best stamina would ejaculate after being served like this by the teacher's skilled oral techniques for so long! Teacher, please don't take it too seriously, just do a little bit and hurry up and continue the lesson!
Sure enough, with this round of demonstration, Chen Yuhao closed his eyes and prepared himself as soon as the head of his penis entered the teacher's mouth. As the teacher's oral sex countdown began, he excitedly tensed his legs. "Tsk, tsk, tsk..." The teacher sucked on his penis with a smacking sound, and Chen Yuhao's brows gradually furrowed. It's okay, only two more times left. Chen Yuhao, hang in there. Teacher Li Zhenzhen, just suck it a little bit. Everyone hurry up and go home. I'll treat you to a late-night snack! Just as the last vibration was about to finish, the teacher forcefully took Chen Yuhao's entire penis into her mouth, even making a "plop" sound as her lips hit her perineum. Then Chen Yuhao's brows relaxed, and he began to tremble his scrotum, obviously ejaculating! It's okay, the teacher still has time. Quickly spit out the head of his penis. My feelings were like a parent whose child has swallowed a button battery. I was thinking to myself, "Quickly tell the teacher to spit out the foreign object in her mouth." The teacher noticed the penis ejaculating in her mouth. The pungent smell of semen made her quickly press her hands against Chen Yuhao's inner thighs, then jerked her head back, trying to spit out the penis and semen. However, Chen Yuhao was incredibly audacious. He tightly gripped the back of Li Zhenzhen's head with both hands. Although he was just a middle school student, the strength of the teacher's neck was no match for the pressure of her hands, especially since Chen Yuhao had been training in fighting. So I watched up close as Li Zhenzhen's eyes widened in terror, tears welling up, just like the face on the poster for the first Scream movie. But while the beautiful woman on the poster only had her mouth open, our Li Zhenzhen's mouth was not only open, but also had an ejaculating penis inside, full of semen! "Oh, so good..." Chen Yuhao ejaculated while holding the teacher's head, pouring all the thick semen into her mouth, and I wondered if it even sprayed down her esophagus. No way! My biology teacher taught me that the stomach is acidic, but last time he told me that male semen is alkaline. Wouldn't that mean acid-base neutralization releases heat?! Won't the teacher's stomach be very uncomfortable?! Thinking this, I practically cried as I ran out the door, grabbed a soda from the vending machine at the tutoring center, and rushed back to the classroom. The teacher's mouth was still on Chen Yuhao's penis!
Finally, when Chen Yuhao was satisfied, he released Li Zhenzhen. The teacher immediately coughed, as if choked by the semen, bending over and making strange noises. That damn pervert! He used class as an excuse to blow-feed the teacher! And the worst part is Li Fa, it's none of your business, yet you're causing trouble over there. Don't give me a chance, or next time I'll definitely fuck your little cunt raw! Who told you to be so stupid? If it weren't for you, the teacher wouldn't have been so choked by the semen! I quickly took the soda to the teacher, who frowned and looked at me: "What are you doing?"
"Semen and stomach acid will neutralize each other, so teacher, quickly use some acidic soda in your mouth to neutralize it first, to avoid stomach discomfort." Actually, before I ejaculated inside the teacher, I had no idea about the term "acid-base neutralization." When the teacher heard this term, she naturally remembered our forbidden exchange, blushed, accepted my soda, and immediately drank a few sips, hoping that even if it didn't neutralize the acid, at least the taste of Chen Yuhao's semen wouldn't linger in her mouth for too long. "Chen Yuhao, you..." The teacher was about to accuse him of disrespecting girls and forcing oral sex when this guy started acting again, preemptively shedding tears: "Teacher, I'm sorry, I've never ejaculated before. I suddenly felt very comfortable, so I couldn't help it, sob sob." Damn, Tang Chenwei and I have both used this trick, each claiming to be a virgin, thinking that would result in a lot of semen, right!? Actually, it's quite effective. As an understanding older sister—no, I mean, a very considerate older sister—Teacher Li Zhenzhen is almost always willing to fulfill our needs, as long as they're not too outrageous and have to be related to the course. Therefore, I really need to study physics and chemistry well so I can intervene at crucial moments. I absolutely don't want to see the teacher's vagina being penetrated by someone else's penis! "What I just demonstrated was the movement pattern of wave motion. Next, I'll explain the generation of sound waves." The teacher adjusted her makeup and continued the lesson. "For a sound to form, an object must vibrate rapidly in a medium, and the frequency must be moderate; too high or too low, and it won't be audible. Of course, the human ear must function normally; the frequency received by the eardrum is the sound frequency, which is the frequency of the vibration source." The teacher then showed pictures of an experiment by Irish chemist Boyle. He evacuated the air from a glass jar, and although the alarm clock inside was still vibrating, no sound was emitted. "This proves that sound propagation requires air as a medium. But in fact, you can still hear sounds from the shore when you're diving in a swimming pool, indicating that gases, liquids, and solids can all serve as sound transmission media," the teacher continued. "Teacher, is this vibration fast enough?" Huang Ruoli, pretending to be mentally challenged and addicted, immediately stood on a chair after hearing the teacher's explanation and made the signature "air sex" gesture of Asian video king Show Lo, exaggeratedly twisting his waist as if performing air sex. He was seen performing air sex at about 5 times per second against the teacher's almost transparent skirt; according to our learned concepts, this frequency is about 5 Hz. Although Huang Ruoli was wearing pants, his large bulge was clearly visible. It was all because the teacher was dressed too provocatively; not only was her upper body revealing a deep cleavage, but her skirt was practically nonexistent, almost revealing her underwear – thin green girl's panties, and if you looked closely, you might even see glimpses of pubic hair. "Not fast enough. The vibration frequency must exceed 20 Hz to make a sound." The teacher smiled and dismissed his efforts, seeing his movements that were practically bordering on idiotic. "How about this?" This time, Tang Chenwei tried to wiggle his butt, but I knew that even a Ricky Martin electric butt vibrator couldn't reach a frequency of 20 vibrations per second. "Impossible. The human ear can hear frequencies between 20 Hz and 20,000 Hz, and
the range of frequencies audible decreases with age." The teacher watched the group of kids trying to twist their waists and wiggle their hips, and although she knew they were fantasizing about her to some extent, she still laughed until she bent over. "Buzzing..." The teacher's lecture was interrupted by a sound. "What's that sound?" The teacher stopped, her smile freezing as she tried to locate the source of the sound. The "buzzing" sound sounded like vibration. Could someone have reached a vibration frequency of 20Hz, emitting sound waves that the human ear could hear? "Hehe, the teacher was right, you can only hear it above 20Hz." Tang Chenwei chuckled and pulled a small, pink object, no bigger than an eraser, from his pocket. He then adjusted the remote control in his hand, and the small object vibrated rapidly one moment and jumped slowly the next. The teacher's cheeks flushed rapidly upon seeing the object. Damn, could that thing be a vibrating egg, an adult toy?! I remembered writing "flea" as "vibrating egg" when I was in junior high school biology class. When my friend Yu checked the communication book, the biology teacher found it and made me write "flea" 100 times as punishment. She called me over to question me, and I honestly admitted that I had written "vibrating egg" as "flea" during a school quiz. Yu's cheeks were almost as red as Ms. Li Zhenzhen's now. Later, I asked my classmates what a vibrating egg was and got vague answers. Now that I see the real thing, I finally understand. "I just turned it on at 10Hz and 15Hz and the teacher didn't hear it, but as soon as I turned it on to 20Hz, the teacher heard it. Sure enough, 20Hz
is within the range of human hearing!" Tang Chenwei happily placed the vibrating egg on the table and let it vibrate "ringing" and "buzzing". "Can you put it away now?" Teacher Li Zhenzhen asked expressionlessly. I had thought she was going to get angry; however, strictly speaking, although Tang Chenwei taking out the vibrator was inappropriate, it was related to the lesson, and it wouldn't make sense for the teacher to suddenly get angry. "Teacher, is a girl's vagina normally closed?" Zhen Shuzhu asked, interrupting the awkward moment. "Why are you asking that?" The teacher was already getting angry, and this seemingly delicate and pretty private girls' high school beauty had asked such a strange question. It looked like the teacher was about to explode! "I just find it strange. If you put a vibrator inside your vagina, wouldn't the vibration be heard? Why do so many erotic novels say that the heroine puts a vibrator inside her vagina and walks around enjoying shameful play without being noticed by passersby? It's so illogical!" Zhen Shuzhu's straightforward, even indignant, question softened Teacher Li Zhenzhen's expression slightly. She continued, "Hmm, it is indeed illogical. A vibrator can vibrate as long as there is a medium, and it is indeed possible for it to make a sound inside the vagina." "Then can you please demonstrate it, Teacher?" Zhen Shuzhu lowered her head, feigning shyness, which was more in line with her status as the school beauty. However, I knew very well that she, who usually liked to make dirty jokes, wouldn't be shy about this!
"Why don't you try it yourself?" the teacher asked sternly. "I'm still a virgin..." Zhen Shuzhu said in a voice barely louder than a mosquito's buzz. I can't refute that, but I think she's probably an Australian pear pretending to be an apple, a Black Widow pretending to be a king crab. "Teacher, we're also curious whether sound changes in nature after passing through the human body. Show us!" Chen Yuhao and Tang Chenwei seized the opportunity to make a ruckus. Thinking about it calmly, the vibrator was brought by them, and all of this development was exactly in line with the plot they had arranged. Teacher, please don't give in to their wishes!
"Well, the teacher also wanted to explain how vibrations change when passing through different media, so I'll reluctantly demonstrate it for everyone." After careful consideration, the teacher decided to insert that seemingly cute but incredibly powerful toy into her body in front of everyone! The teacher took the vibrator and wireless remote control from Tang Chenwei, then decisively lifted her skirt, took off her panties, and sat on the empty table she used to put things on, legs spread in an M-shape. I saw the teacher's long legs bent in the most lewd posture, and my lower body was already restless. When I looked at the teacher's darker genitals, I saw that her labia minora were engorged and spread open, the opening in the center of her vagina slightly exposed, and the surrounding area was moist and reflecting light. My penis was already erect in my pants. "Everyone, listen to the sound at 20Hz. This is the control group." The teacher held the thin string at the top of the cute vibrator, making it vibrate in the air. You could indeed hear the sound. "Next up is the experimental group, please listen carefully." The teacher leaned back slightly, nervously lowered her head, parted her most private parts, and then inserted the vibrator into her vagina. "?" "Quiet!" Tang Chenwei excitedly told everyone not to make any noise. "Did the teacher turn it on?" As the vibrator lewdly burrowed into the teacher's pink flesh, completely buried in the layers of her vaginal walls, with only a thin thread showing, we heard no sound. "It's on." The teacher frowned, her voice trembling. So the teacher pulled the vibrator out halfway, leaving only half of it outside her vagina, and we began to hear the buzzing sound again, and witnessed firsthand how the vibrator served the teacher's thin labia minora, making the two little petals vibrate in a sexy way. "If you don't believe me, feel the teacher's stomach." The teacher almost begged to end the experiment quickly, asking us to touch her lower abdomen to see if we could feel the vibration coming from her vagina. The teacher deliberately phrased it subtly, saying we should touch her stomach. Actually, the area where we could feel the vibration was closer to the vibrator. But being a gentleman, I first touched her small hand. She was currently spreading her thighs to allow classmates to observe the changes in her genitals. Finding no movement, I then hurriedly placed my hands near her lower abdomen, especially between her pubic hair and navel. Several perverts simultaneously reached out, and sure enough, I felt a very strong vibration through her skin and subcutaneous tissue. "It really is!" Zhen Shuzhu exclaimed excitedly. Even though she couldn't hear a sound, she could feel the vibration inside the teacher's stomach. She happily raised her hands, making her B-cup breasts stand out even more through her school uniform shirt. "No, I need to confirm." Tang Chenwei snatched the remote control from the teacher's hand. Because her most vulnerable area was being subjected to an attack so intense she couldn't speak, her hand slipped, and Tang Chenwei took the remote. "It's really on!" Tang Chenwei saw the LED display on the remote and then incredulously turned up the frequency. How did I know? Ah, Lin Bei's hand was on the teacher's mons pubis! "Students, remember, the frequency of a wave doesn't change when it penetrates different media, but..." The teacher frowned as if she was in great pain, but actually it was because Tang Chenwei was mischievously switching frequencies, and the teacher was probably already enjoying herself to the point of almost losing control. The old woman's vagina was already enduring a high-speed attack that even Kato Taka couldn't match, and some students even took advantage of the chaos to grope the teacher. I noticed Huang Ruoli's hands were improperly touching the teacher's clitoris and labia, while several of Chen Yuhao's followers were stroking the inside of the teacher's thighs; some people even tried to insert their fingers into the teacher's vagina and anus, but I slapped them away, but countless others failed to defend themselves, and the teacher was groped dozens of times. "Wait, wait!" The teacher's fair collarbone and thighs suddenly flushed red, interrupting her explanation. She leaned back and begged Tang Chenwei to stop. However, Tang Chenwei was enjoying the pleasure of humiliating his teacher, so how could he stop? He retreated far away from his teacher and continued to adjust the remote control in his hand until the teacher couldn't take it anymore and awkwardly pulled the vibrator out of her body before losing control. The deafening buzzing sound made us realize that this little guy was too powerful!
The teacher glared at Tang Chenwei, then continued, panting, "When a wave passes through different media, the frequency doesn't change. So when Tang Chenwei turned up the frequency, you could hear it through my stomach. However, the amplitude, wavelength, and wave speed changed. In the air, because the amplitude is large enough, you can hear the vibrating egg. But inside my body, although the vibrating egg still vibrates, firstly, there's no air as a medium inside my vagina, so I can't hear the buzzing sound like in the air; secondly, the amplitude isn't large enough. The energy of the vibrating egg isn't enough to disturb my body and produce a large enough amplitude, so you can't hear the sound." Although the teacher was panting, she still managed to explain everything she wanted to say in one breath. It seemed she had taken Jiang Wangcheng's advice to heart, that sly, fat man, to heart. The more she faced a crisis, the more she could turn it into an opportunity. "Teacher, could you demonstrate again?" Tang Chenwei made a pleading gesture with both hands and even handed over the remote control, wanting the teacher to know his sincerity. He "really" just wanted to learn properly. "Hmm." This time, the teacher first placed the vibrating egg near the clitoris and labia minora, letting the students see clearly that if it were a thin object like the labia minora, the vibrating egg could transmit energy to cause them to vibrate at a high frequency and also make a buzzing sound. However, I think even if the labia minora really vibrated at 20 times per second, it shouldn't make a sound, otherwise it would be too incredible! Then the teacher couldn't wait to insert the vibrating egg into her vagina. This time, without Tang Chenwei's interference, she could actively control the frequency. She quite enjoyed using the guise of demonstration to openly masturbate. She slowly increased the frequency and occasionally pulled out the vibrating egg to stimulate her clitoris. "Hmm~~~" The teacher's muffled moans became more and more obvious under the students' indifferent attitude. She squinted her eyes, frowned, and sweat slowly slid down her temples. Her body trembled slightly, whether from the vibration of the vibrating egg or from her own pleasure. "To the students who came for tutoring last week, I'm going to test if you've learned how to vibrate. Xiaoping, you stimulate my nipples at a high frequency." The teacher didn't even glance at me before pulling down her shirt and unhooking her front-opening bra, revealing her slightly swaying, fair breasts. Of course, I was more than happy to oblige. I quickly stepped forward, gently flicking the teacher's pink nipples with one hand each. Those pink tips were already erect, no wonder people call them "pepper nipples." Even though the teacher's breasts were so large, her nipples were still slightly upturned like chili peppers, their color a fiery red full of lust, and their shape so cute that one wanted to put them in their mouth. However, some people say that pepper nipples refer to the fragrance like Sichuan peppercorns. I haven't licked them, so I dare not make a judgment. At this moment, without my defense, the teacher's clitoris had already surrendered. Huang Ruoli parted the teacher's clitoral foreskin and lewdly rubbed the teacher's little bean. Afraid of being discovered by the teacher, he licked the corner of his mouth while rubbing the teacher's clitoris, all the while watching whether the teacher's eyes were open. Chen Yuhao also tentatively tried to insert his finger into the teacher's vagina, but the vibrator was already inside her. He could only poke and rub the entrance of her wet vagina, unable to actually insert his finger. "Teacher, we've seen enough. Thank you for your insightful guidance and your great spirit of sacrifice." Seeing that the teacher was already indulging in lustful pleasure, his comrades were more concerned with their own enjoyment, completely forgetting that inserting their penises into the teacher's body was the ultimate strategic goal. Tang Chenwei, on the other hand, was a little annoyed and put on a rare show of gratitude. Kids, they're only happy when others are happy, that's what you call the rebellious phase. The teacher was a little surprised, after all, Tang Chenwei had never said thank you before, except when calling a female classmate surnamed Xie, Xie Chenying. "Teacher, please give me back the vibrator." Tang Chenwei put on a stern face, took out a tissue, and prepared to take the vibrator, which was now covered in the teacher's secretions. "Pfft~~~~~~" Just as the vibrator left the teacher's vagina and she leaned back to return it to Tang Chenwei
, an embarrassing fart sound echoed through the classroom! My instinct was to cover my nose, but the astonishing scene before me left me stunned. I was certain it wasn't a fart, because the teacher's labia minora were trembling from the force of the air expelled from her vagina! Good heavens, the fart sound was coming from the teacher's vagina. Teacher Li Zhenzhen looked so innocent, yet she could fart from there! Not only was the teacher embarrassed, but I was also utterly ashamed. "Teacher, have you ever given birth?" At this moment, Li Fa stood up expressionlessly and asked. This temporarily made everyone overlook the astonishing sight of the teacher's vagina farting. "Of course not, I'm unmarried," the teacher replied, straightening her posture. "That sound is commonly known as vaginal flatulence or vaginal fart, usually caused by vaginal laxity after childbirth."
Li Fa continued, his face flushed with displeasure, "If the teacher hasn't given birth, then it's because the pelvic floor muscles contracted, causing spasms in the uterus. The pressure decreased, and the moment the vibrator was pulled out, a large amount of air was forced into the vagina and uterus. Then, when changing positions, the vagina or uterus was under pressure, resulting in a large amount of gas being expelled, similar to farting." I thought about it, and it was indeed because the teacher leaned back that she made a farting sound between her legs. Otherwise, she would have been playing with the vibrator for half the class, and I hadn't heard any sound. "And the uterus spasming, simply put, means the teacher had an orgasm." Li Fa glared at the teacher resentfully, then rudely sat down. Damn, no wonder the teacher repeatedly pulled the vibrator out of her vagina to stimulate her clitoris, intentionally or unintentionally. I'd heard of a theory that there's no such thing as a "vaginal orgasm," and that achieving orgasm mostly relies on clitoral stimulation; it turns out that Teacher Li Zhenzhen had just taken the opportunity to stimulate her clitoris with the vibrator, and the moment her thighs and collarbone flushed was her first orgasm!
"Huh?" Hearing that the teacher had actually climaxed in class while demonstrating the movement, Tang Chenwei, Chen Yuhao, and the others started making a ruckus: "How could the teacher do that? She's only enjoying herself and doesn't care about us!" "The teacher is unprofessional!" The kids' protests rose and fell. The teacher was speechless. After all, what Li Fa had just said sounded reasonable. She had told me last week that she had an aunt who had taught her a lot about male and female anatomy. I don't think she was just making it up. At that moment, even I, who had just been asked to help stimulate her nipples, started to dislike Teacher Li Zhenzhen! However, seeing that class was over, the teacher had no chance to salvage the situation and could not bribe the students with her body. She could only shamefully put her underwear back on and watch the kids walk past her with disdain. [To be continued] [Last edited by Ye Xuanxingchen]
