My mother and I demonstrated sexual intercourse.

This happened when I was in fifth grade. That June, after the final exams, I was free at school when Ms. Chen asked if I could help tutor a junior. Of course, I said no problem, because Ms. Chen was the most beautiful woman in the school; although she was married, she was still stunning. Ms. Chen also asked me to bring my mother, saying she could treat us to dinner after class to thank me for my help, so I brought my 38-year-old mother along.

My mother's name was Huang Meilian, and she was 38 years old at the time, 5 feet 2 inches tall, with measurements of 36C-25-34. I was 17 years old then, 6 feet tall, and weighed 120 pounds, making me one of the most handsome men in the school, so it wasn't surprising that the teacher asked me for help, and I was happy to help Ms. Chen.

That day, I arrived at the small room next to the classroom very early in the morning, and my mother came with me.

"Li, you're here really early; did you bring your student ID?"

"Yes."

After handing over my student ID to Teacher Chen, she took a set of patient clothes from a drawer and gave it to me. "Turn left at the end of the door, there's a changing room on your right. Take off your clothes and pants and change into this hospital gown."

Looking at the "set" of clothes in her hand, it was at most just a piece of cloth with two sleeves sewn on.

After taking off my outer clothes and pants, I hesitated whether I should also take off my underwear. Two years in the army had indeed made me more thin-skinned, so I decided to wear my underwear and put on the patient gown before returning to the office.

"Li, did you take off your underwear too?"

"Ah, no."

"Then take it off."

"Okay."

It was the first time I took off my underwear in front of Teacher Chen without doing anything. After taking it off, I couldn't help but tug at my clothes, as if I was worried that Teacher Chen would see my private parts. Teacher Chen lowered her head slightly and glanced at my lower body before returning her gaze to the table and continuing to type. I, on the other hand, felt like I was sitting on pins and needles, fidgeting and constantly tugging at my clothes. Finally, Teacher Chen stood up, nodded to me, and led me into an empty room.

"Li, please wait here for a moment."

"Okay."

Then she opened the door and walked into the adjacent classroom. She could hear many people whispering inside, very quietly.

"Classmates, to help you get into the swing of things as soon as possible, the school has arranged for the upperclassmen to help you with a live dissection."

The upperclassmen must be referring to me? Live dissection? I was filled with endless confusion.

"Live dissection not only explains the organs of the human body, but also hopes that you will use touch, sight, smell, and even hearing to gain a deeper understanding of the human body."

For some reason, a vague sense of unease crept into my heart.

"Well then, let's welcome Li, the senior student, with an open mind."

At this moment, Teacher Chen opened the door again. "Li, it's alright, please come to the front of the classroom."

It turned out that she had just entered a classroom. Inside, she saw about thirty male students sitting in their seats (because I attended an all-boys school). They were all craning their necks to look at me, their eyes seemingly shining.

"Yes, everyone, please treat Li as a living person for now; it will make the lesson run more smoothly."

Teacher Chen then turned to look at me. "Li, please take off your patient gown."

Uh, if I take off this patient gown, won't I be naked in front of these thirty-odd men? Hearing the lecturer say this, the male students began to whisper among themselves.

"Class, please raise your hand if you have any questions. Whispering like this is very impolite to me, and to this living, breathing person on stage—uh, I mean, Li."

He continued to look at me, seemingly waiting for my next move. I reluctantly removed the cloth covering my sleeve. After Professor Chen took it, all eyes were on me, naked in front of the podium.

"Yes, what is presented before you is a male body. You can clearly see that the biggest difference between a man's body and your own is that he lacks breasts; instead, he has thicker muscles. And the lower body..."

The professor gestured for me to raise my hands covering my genitals. "We can see that the male lower body consists of the penis and scrotum."

This was the first time I had been naked in front of men, and in front of more than thirty men at once.

"Actually, you'll have many opportunities to see male bodies after graduation, whether it's male patients or your boyfriends, but none of those will be like today, where you can get to know the different parts of a man. Okay, does anyone have any questions?"

"Teacher..."

A student raised his hand. "Um, Wang, please go ahead."

"I want to ask, how do men have sex?"

"Very good question. Although it's not part of today's male anatomy lesson, I'll explain it to you anyway. Sexual intercourse is the insertion of the male sex organ, the penis, into the male vagina."

"But how can this limp penis be inserted into a vagina?"

The speaker was Wang, who had just raised his hand, and his slightly cunning eyes were now looking at me.

"Yes, today is Li's first time demonstrating a live anatomy, so he's a little nervous. When a normal male is stimulated, his penis will become erect due to increased blood flow, and once erect, it can be inserted into the male body."

"Teacher, could you please demonstrate an erection using a live anatomy? I mean, could you please have Li demonstrate an erection?" It was Wang who spoke again.

"At this point, it's probably impossible for Li to get an erection naturally, so I'll give him some stimulation. Everyone should approach today's live anatomy class with caution, and don't mistake it for a pornographic demonstration."

As he spoke, the instructor turned to face me, nodded to me, and then touched my penis with his hand.

"Class, please come a little closer to observe the changes in the live penis today."

At this moment, the instructor held my penis, and the students below the stage all moved closer, as if watching an interesting little animal. My penis, which was originally contracted due to tension, unexpectedly began to respond and gradually became erect under the watchful eyes of more than thirty young men and the touch of the beautiful female instructor.

"Wow, it's really hard!"

Under the female instructor's caresses, my penis went from contracted to erect.

"Class, this is a male penis in its arousal phase."

"Teacher, can we touch it?"

It was Wang again who asked. "Okay, today I hope that you all can thoroughly understand the structure of the male body through different sensations. Now, according to the seating order, remember to be gentle when touching it, as the male penis can be quite sensitive at times."

The men lined up neatly in front of me, waiting to touch my penis. So this is what teaching models does.

At this moment, the teacher removed the hand that had just grasped my penis. "Now everyone, take turns touching the male penis and scrotum."

The first student slowly extended his right hand, touched the penis with his fingers, and then withdrew it, causing the other students behind him to burst into laughter. The second one was Wang, the student who had asked many questions earlier. She reached out and grasped my penis without hesitation, and even moved it back and forth a few times. This action was just like the action I take when masturbating, except that this hand was not my hand, but the hand of a very young girl with a pretty face.

"Teacher, you just said that we can experience the male body through touch and smell. Can I smell a male penis?"

"Hmm, okay, but remember to be careful."

Wang looked up, gave me a sly look, and then lowered his head to smell my penis.

"Teacher, male bodies don't really smell. I wonder what they taste like."

Before the lecturer could answer, Wang actually put my penis in his mouth, sucked it twice, and then slipped off the stage. The other students, some shyly touched it, some held the whole penis and stroked it slightly like Wang, and some bolder ones even bent down to smell it. But no one dared to open their mouths and put my penis in their mouths like Wang.

Finally, all thirty-odd male students in the class had taken turns playing with my penis. At this point, my penis was extremely erect due to the great stimulation, and the tip of the glans even secreted a little prostate fluid, making it wet.

"Teacher, you just mentioned male-male sex, could you demonstrate it?"

The questioner was still the same student, Wang. "As for male-female sex, it's not convenient for the teacher to demonstrate it in class. Let's assume this is a woman's vagina."

As he spoke, the lecturer circled his left hand. "This is how a male penis is inserted."

The lecturer brought his circled left hand close to my penis and began to stroke it back and forth. "However, usually during sex, the man is the one who initiates the movement, performing the piston-like motion after penetration."

"Then, teacher, could you please have student Li demonstrate, pretend to have sex with the teacher, I mean, with the teacher's hand, and show us?"

The female lecturer glanced at me and nodded, indicating that I should demonstrate. Good heavens, didn't this lecturer know that besides masturbating a few times, I was actually a complete virgin? Oh well, I had no choice but to follow the scenes from porn in my head and pretend to have sex with the lecturer's hand. Sigh, I never thought my first time as a virgin would be so unromantic, openly having sex with the left hand of a rather unattractive lecturer in front of over thirty male students.

"Classmates, this is what sex is, but real sex isn't with a man's hand, it's with the vagina. Any other questions?"

"Teacher, how does a man ejaculate?"

Finally, it wasn't student Wang asking anymore, but this question was even more explosive.

"Well, when the male penis is making piston-like movements inside the male vagina, after some back and forth movements, the male will eventually reach orgasm, which is ejaculation."

"Can you demonstrate it for us?"

"This sex is different from the hand-holding game with the teacher, it's difficult to demonstrate."

"Then we can invite a student who is willing to come up on stage to demonstrate."

Student Wang challenged again, "Although such a demonstration may cause some students to have erotic fantasies, ignoring that eroticism and teaching are on the same level, alright, is there any student who is willing to come up on stage to demonstrate?" The students

looked at each other, and suddenly fell silent.

Teacher Chen didn't expect that when it came to the real thing, no one dared to try. "Alright then, I'll ask Li's mother to help out. Mrs. Li, please come up on stage and demonstrate sex to us. Everyone, please applaud and encourage her. Mrs. Li wasn't originally here to demonstrate."

Then, my mother, Li's mother, came up on stage. My mother was nervous and a little shy, and had never thought about demonstrating sex with her own son.

"Mrs. Li, then please take off your clothes and demonstrate for the other students."

My mother didn't hesitate and took off her coat and long skirt, revealing a pure white bra and panties. Then she took off her bra and panties, and her C-cup breasts popped out, with light brown nipples. Her pubic hair was sparse but neatly growing on her mons pubis. She was only wearing 3-inch high-heeled sandals. I had never seen my mother's body before, and it was very sexy.

"Dear students, although Ms. Li is your mother, she is still very young and has given birth, making her a mature mother. Before the demonstration, let me briefly explain the different parts of the female body."

The instructor asked my mother to sit on the platform, placing her feet, clad in high-heeled sandals, on the edge of the platform, bending her legs into an M-shape, exposing her labia to the other students.

"Dear students, this is the labia majora, and this is the labia minora, the clitoris. Inside the labia minora is a small opening, the one I'm inserting the pen into now. This is the urethra. Many first-timers often accidentally enter the urethra, causing extreme discomfort for the woman."

My mother displayed her genitals, blushing as she glanced back at me before turning away.

"Next, look below the urethra. There's a larger opening; that's the vagina. The vaginal surface has a thin membrane, commonly known as the hymen. Oh dear, Li Mama, your hymen is broken, isn't it? The small, tightly closed hole below is the anus, which is generally only used for defecation."

"Teacher, what do you mean by 'generally'? Isn't the anus only used for defecation?" a boy in the back asked.

"Yes, because some abnormal sexual intercourse involves the anus, that's called anal sex! Only very lewd people do it, it's a perverted thing."

A boy said again, "Can you demonstrate? Can you really insert the penis?"

"This is abnormal sexual behavior, only lowly women do it." The teacher turned to the mother and asked, "Ms. Li, would you be willing to demonstrate sexual intercourse with your mother now, and then teach anal sex next week?" "

Yes, as long as it can help these students, and my son is willing to cooperate, I don't object." The mother agreed without thinking.

"Student Li, are you willing?" Teacher Chen asked me in a slightly sexy tone.

"Teacher Chen, it's okay, I'm willing." Of course, I couldn't resist Teacher Chen's request.

"Well, since the parties involved have no objections, please come over here, Li."

I walked to the front of the podium, standing there a little lost, but my eyes were drawn to my mother's genitals. Her light brown labia were slightly damp, extremely beautiful, and my erect penis couldn't help but nod in agreement.

The instructor pushed me closer to my mother, pointing my glans towards her vagina. "Students, please move closer, but don't disturb the two on stage. Find a spot where you can see clearly."

The students crowded around the podium like they were watching a show. Once everyone was in position, the instructor grabbed my penis, preparing to demonstrate this classroom erotic show. "Teacher, is this how sex is done, with the man directly penetrating?"

a student asked. "Generally speaking, is there a foreplay before sex?" "Foreplay includes caressing and oral sex, and I've already demonstrated oral sex to the students,"

Teacher Chen said. "Then let me demonstrate caressing a woman."

The instructor held my penis and gently stroked it back and forth. Although I felt a little uncomfortable in front of more than thirty men, it felt really good, so I closed my eyes to enjoy it. At this moment, I felt the instructor squeeze my penis slightly, and I quickly opened my eyes again.

"Next, I will demonstrate male caressing and oral sex on a woman."

The instructor gestured for me to lower my head, so I lowered my head to face my mother's genitals. "When a man licks a woman's clitoris and labia with his tongue, it is called oral sex."

The instructor nodded, so I licked my mother's labia, and at that moment my mother trembled as if she had been electrocuted.

"Due to time constraints, the instructor will give us a brief demonstration. Next, you will see how a man has sex with a woman."

The instructor nodded to me again. I raised my erect penis and slowly approached my mother's already wet vagina, slowly inserting it until the entire penis was inside. At this point, the female instructor signaled for me to pause. "Yes, the action I just demonstrated is having sex. Does anyone have any questions?"

"Teacher Chen, Li's penis wasn't fully inserted. Is that okay?"

"Yes, that's because the penis only went to the end of the vagina. Li's penis is 11 inches long; any further and it would have entered his mother's uterus." "

Is that not okay?" another student asked.

"Yes, that's fine, but it's just a demonstration. You don't need to insert it all the way in," Teacher Chen explained. "How about this, Li, you insert it a little further, until it reaches the uterus, okay?"

"Let me help!" Mom offered, then slowly moved her body, gently swallowing my penis into her vagina. I could feel it passing through her cervix. "Ahhh!" Mom groaned.

"Looks like it's inside the uterus," Chen Youshi began his academic explanation, but I didn't hear a word. My whole body was focused on the pleasure of my penis thrusting into her uterus. Involuntarily, I continued thrusting into my mother.

"Teacher, what was that 'Ahhh!' sound that the lady made?" a male student asked, even mimicking his mother's moans.

"Oh! That's moaning. When you experience sexual pleasure during intercourse, you make joyful noises. But what you just heard was really vulgar; you could call it 'lewd moaning!'" The teacher explained without any politeness, in a serious tone.

"Teacher, can I watch the whole process of making love? Also, what is anal sex?"

"Okay, since this class is about to end, let's ask Li and Li's mother to demonstrate other sexual acts for us after class."

After saying that, the instructor gestured to me, so I pulled out my penis that was inserted into my mother's vagina. Unexpectedly, after nearly fifty minutes of stimulation, just as I pulled out my penis, yes, I ejaculated. Amid the exclamations of the other students, I ejaculated the unfinished semen from our lovemaking, shooting it all over my mother's belly.

Perhaps unexpectedly, Teacher Chen suddenly fell silent, staring at the semen I ejaculated on Wang's stomach for a long, long time, until the next student asked... "Teacher, is this ejaculation?"

"Uh, yes, although today's sex demonstration wasn't a complete set, Li was probably stimulated by everyone and ejaculated while withdrawing his penis. That's semen, no doubt."

The instructor picked up the semen with her finger. "Students, if these drops of semen were ejaculated into a woman's vagina, it could potentially cause pregnancy. So, before you decide to have a baby, you must wear a condom during sex to avoid causing a pregnancy while enjoying yourself." My mother

looked at me, her blushing face and slightly hazy eyes were extremely beautiful. I couldn't help but reach out and grab her leg, wanting to caress her passionately, until the female instructor's soft cough startled me.

"That's about time. You can take turns touching my semen, but be careful to wash your hands afterwards."

This absurd "live dissection" class ended amidst the class's uproarious laughter and the rush of students touching my semen.

This happened when I was in fifth grade. That June, after the final exams, I was idle at school. One day, Ms. Chen asked if I could help tutor a junior student. I naturally said no problem, because Ms. Chen was the most beautiful woman in the school; although married, she was still stunning. Ms. Chen also asked me to bring my mother, saying she could treat us to dinner after class to thank me for my help, so I brought my 38-year-old mother along.

My mother's name was Huang Meilian. She was 38 years old at the time, 5 feet 2 inches tall, with measurements of 36C-25-34. I was 17 years old, 6 feet tall, and weighed 120 pounds. I was one of the most handsome men in the school, so it wasn't surprising that the teacher approached me. I was happy to help Teacher Chen.

That day, I arrived at the small room next to the classroom early in the morning, and my mother came with me.

"Li, you're here very early; did you bring your student ID?"

"Yes."

After handing Teacher Chen and my student ID, she took a set of patient clothes from the drawer and gave them to me. "Turn left at the end of the door, there's a changing room on the right. Take off your clothes and pants and change into this hospital gown."

Looking at the "set" of clothes in her hand, it was at most just a piece of cloth with two sleeves sewn on.

After taking off his outer clothes, he hesitated whether he should also take off his underwear. Two years in the army had indeed made him more thin-skinned. He decided to wear his underwear and put on his patient gown before returning to the office.

"Li, did you take off your underwear too?"

"Ah, no."

"Then take it off."

"Okay."

It was the first time I took off my underwear in front of Teacher Chen without doing anything. After taking it off, I couldn't help but tug at my clothes, as if I was worried that Teacher Chen would see my private parts. Teacher Chen lowered her head slightly and glanced at my lower body before returning her gaze to the table and continuing to type. I, on the other hand, felt like I was sitting on pins and needles, fidgeting and constantly tugging at my clothes. Finally, Teacher Chen stood up, nodded to me, and led me into an empty room.

"Li, please wait here for a moment."

"Okay."

Then she opened the door and walked into the adjacent classroom. She could hear many people whispering inside, very quietly.

"Classmates, to help you get into the swing of things as soon as possible, the school has arranged for the upperclassmen to help you with a live dissection."

The upperclassmen must be referring to me? Live dissection? I was filled with endless confusion.

"Live dissection not only explains the organs of the human body, but also hopes that you will use touch, sight, smell, and even hearing to gain a deeper understanding of the human body."

For some reason, a vague sense of unease crept into my heart.

"Well then, let's welcome Li, the senior student, with an open mind."

At this moment, Teacher Chen opened the door again. "Li, it's alright, please come to the front of the classroom."

It turned out that she had just entered a classroom. Inside, she saw about thirty male students sitting in their seats (because I attended an all-boys school). They were all craning their necks to look at me, their eyes seemingly shining.

"Yes, everyone, please treat Li as a living person for now; it will make the lesson run more smoothly."

Teacher Chen then turned to look at me. "Li, please take off your patient gown."

Uh, if I take off this patient gown, won't I be naked in front of these thirty-odd men? Hearing the lecturer say this, the male students began to whisper among themselves.

"Class, please raise your hand if you have any questions. Whispering like this is very impolite to me, and to this living, breathing person on stage—uh, I mean, Li."

He continued to look at me, seemingly waiting for my next move. I reluctantly removed the cloth covering my sleeve. After Professor Chen took it, all eyes were on me, naked in front of the podium.

The instructor nodded to me again. I raised my erect penis and slowly approached my mother's already wet vagina, slowly inserting it until the entire penis was inside. At this point, the female instructor signaled for me to pause. "Yes, the action I just demonstrated is having sex. Does anyone have any questions?"

"Teacher Chen, Li's penis wasn't fully inserted. Is that okay?"

"Yes, that's because the penis only went to the end of the vagina. Li's penis is 11 inches long; any further and it would have entered his mother's uterus." "

Is that not okay?" another student asked.

"Yes, but this is just a demonstration. You don't need to insert it all the way in," Teacher Chen explained. "How about this, Li, you insert it a little further, until it reaches the uterus, okay?"

"Let me help!" Mom volunteered, then slowly moved her body, gently swallowing my penis into her vagina. I even felt my penis pass through the cervix. "Ahhh!" Mom groaned.

"It seems it has entered the uterus," Teacher Chen began his academic explanation, but I didn't hear a word. My whole body was only focused on the pleasure brought by my penis thrusting into my uterus. Involuntarily, I thrust into my mother.

"Teacher, what was that 'Ahhh!' sound that the lady made?" a male student asked, even imitating his mother's moan.

"Oh! That's moaning. When you experience sexual pleasure during intercourse, you make joyful noises. But what you just heard was really vulgar; you could call it 'lewd moaning!'" The teacher explained without any politeness, in a serious tone.

"Teacher, can I watch the whole process of making love? Also, what is anal sex?"

"Okay, since this class is about to end, let's ask Li and Li's mother to demonstrate other sexual acts for us after class."

After saying that, the instructor gestured to me, so I pulled out my penis that was inserted into my mother's vagina. Unexpectedly, after nearly fifty minutes of stimulation, just as I pulled out my penis, yes, I ejaculated. Amid the exclamations of the other students, I ejaculated the unfinished semen from our lovemaking, shooting it all over my mother's belly.

Perhaps unexpectedly, Teacher Chen suddenly fell silent, staring at the semen I ejaculated on Wang's stomach for a long, long time, until the next student asked... "Teacher, is this ejaculation?"

"Uh, yes, although today's sex demonstration wasn't a complete set, Li was probably stimulated by everyone and ejaculated while withdrawing his penis. That's semen, no doubt."

The instructor picked up the semen with her finger. "Students, if these drops of semen were ejaculated into a woman's vagina, it could potentially cause pregnancy. So, before you decide to have a baby, you must wear a condom during sex to avoid causing a pregnancy while enjoying yourself." My mother

looked at me, her blushing face and slightly hazy eyes were extremely beautiful. I couldn't help but reach out and grab her leg, wanting to caress her passionately, until the female instructor's soft cough startled me.

"That's about time. You can take turns touching my semen, but be careful to wash your hands afterwards."

Amidst the whole class's uproarious laughter and the rush of people touching my semen, this absurd "live dissection" class came to an end.
