This happened when I was in my third grade of health school
In June that year, the graduation exam had just ended. I was idle on campus, so I went to see my first-grade class teacher, Mr. Chen.
Teacher Chen has always taken good care of me, and I am very grateful to her
I sat in Teacher Chen's office for a while and chatted about the past. As I was talking about the human anatomy class she had recently. She said that the students she taught are very stupid when studying now. She asked me if I could help teach my juniors. Of course, I said no problem, because Teacher Chen is my favorite teacher and the best beauty teacher in the school.
Of course I have to do my best to ask for my help if such a beautiful teacher.
At that time, Teacher Chen was about 34 or 35 years old. Although he was already married, he was still beautiful and charming.
When she went to take our class, I was the class monitor. She never concealed her preference for me, and even caused jealousy among many boys in the class. Unfortunately, she only taught me for two years. When she was in the third grade, she changed a male teacher, and Teacher Chen returned to the first grade to take care of her current class.
I asked: What do you need me to do?
Teacher Chen smiled and said: Just to show your juniors and sisters.
Make a demonstration? What kind of demonstration?
I have never taken any human body demonstration class in my memory!
Teacher Chen smiled and said that he would know by then. When I saw that she didn't want to talk more, I stopped asking more questions.
Teacher Chen asked me to call my mother here again, so I could invite us to dinner after class, thank you for your help.
I didn't want Teacher Chen to invite her to dinner, but then I thought, can I take this opportunity to contact the teacher more! And I can also take the opportunity to invite her back! So I agreed.
My mother's name is Huang Meilian, and she was a doctor. She was 38 years old at the time, and was 1.68 meters tall. She had a measurement of 35, 24, 36. She had a standard model figure.
I was eighteen years old at that time, 1.78 meters tall, weighed 69 kilograms, and was a recognized handsome man.
The next morning, my mother and I came to Teacher Chen's office. Although her office is not big, it is a room for each person. Although the furnishings inside are simple, they are very clean.
Hello, Teacher Chen! This is my mother
I introduced them to both of them, and Teacher Chen couldn't help but praise him when he looked at my mother: Classmate Li, your mother is such a beautiful woman!
Mom smiled and said: Teacher Chen is also very beautiful!
Teacher Chen made tea for us and said: Please wait a moment, this class has not ended yet, the next one is my human anatomy class.
So my mother and I were drinking tea and chatting. Soon it was time to finish class. The classroom next door suddenly became lively. A few girls came to the door of Teacher Chen's office and looked in.
What do you think? Don’t you know that this is impolite?
Teacher Chen said with a straight face
A girl stretched out her tongue and said: Didn’t the teacher announce that the next class is a human body demonstration class? We want to see the nude model first.
Teacher Chen laughed: OK, you saw it too, are you satisfied?
The girl asked with a smile: There are two people here in the teacher. Which mannequin is today?
There are boys and girls in our class, and these two are nude models invited by the teacher!
At this time, the bell rang for class, and the girls rushed back to the classroom. Teacher Chen also stood up and said to me and my mother: Please come with me, two,
The classroom is next door when we entered the classroom with Teacher Chen, there were more than 40 students sitting inside, and the male-female ratio of the whole class is about 1:1
Teacher Chen asked my mother to sit down on a chair, and then asked me to stand in front of the podium.
Students, today we have the honor to invite senior Li Xiaoming and his mother Huang Meilian to be a nude model for everyone. Later, you can understand the difference between men and women through physical observation.
More than 40 students from the audience applauded together
I suddenly felt something was wrong, but now it's too late to regret
Classmate Li, please take off your clothes
Teacher Chen nodded at me
I took off my only sweatshirt with a stinging body, revealing my pretty muscular breasts
Please take off your pants, too
I glanced at Teacher Chen, and she looked at me firmly, so I had to take off the sports shorts again
There is also the pair of briefs that need to be taken off, Teacher Chen continued
If you take off, you will be naked? Standing naked on the podium in front of so many students in the class, is this what Teacher Chen calls a human body demonstration?
I took off my only underwear again, and my hands covered the hidden part of my lower body.
The whole class looked at me with more than 40 pairs of eyes. This was the first time I was so old that I took off naked in front of everyone, and more than 20 were women.
In order to teach in comparison with male body, I would like to ask Mrs. Li to come on stage to demonstrate female body for us. Can Mrs. Li?
When I was looking at Teacher Chen in surprise, my mother had already stood up from her seat. She walked to the front of the podium a little shyly and asked: Teacher Chen, do I want to take off my nakedness too?
Teacher Chen nodded and said: Not bad, does Mother Li agree?
Mom hesitated for a moment, and I thought she would not agree, but my mother looked at Teacher Chen and said: Well, in order for the students to learn knowledge, I am willing to be a demonstration of female entities.
After saying that, my mother took off her skirt. She was wearing a set of blue floral lace underwear. The underwear was designed very sexy. Except for a piece of paper-sized cloth in front that was embroidered with a few flowers, the rest were almost all transparent.
Mom seemed to have made up her mind. She took off her underwear without any hesitation and stood beside me openly
This is the first time I saw my mother naked, but I didn’t expect her figure to be so good!
Her breasts are big and firm, her abdomen is smooth and tight, her legs are long, and her buttocks are slightly upturned. She looks very tall and beautiful because she is wearing a pair of five-centimeter-high orange high heels.
Students, now there is a male entity and a female entity standing in front of you. I want to ask a student to tell you about their differences.
Teacher Chen tapped me with the instruction stick and said
I put my hands behind me awkwardly, and my penis hung softly due to tension, making me feel a little funny.
Several students in the audience raised their hands
Hu Yumei, please tell me
Teacher Chen pointed at a girl wearing glasses in front with a teaching stick.
The male has a prominent Adam's apple but the female does not, the female has plump breasts but the male does not. The hu classmate said
Is there any more? Teacher Chen asked
This... Classmate Hu suddenly turned red with his face. She shook her head and sat down.
Classmate Wang Yingying, what are the differences between male and female entities? Teacher Chen pointed to another girl and asked
This time, Wang, who stood up, was the most courageous girl who stood at the door of Teacher Chen’s office just after class. She had a medium figure and a pair of big, watery eyes, and looked very beautiful.
The biggest difference between men and women is their genitals
Student Wang said in a crisp voice, the male genitals have a protruding penis, while the female genitals are a hole that cannot be seen on the outside. There is also a hole in the male genitals, but the female does not.
Teacher Chen said in an approving tone: Student Wang’s analysis is very correct and good. The male external genitals are composed of a penis and a scrotum.
Teacher Chen pointed at the corresponding part of my lower body with a teaching stick and explained: As for women, the entire external genitals are relatively secret. Can you please sit on the podium and show your external genitals to your classmates?
OK
Mom agreed readily. She sat on the podium, her feet in high heels stepped on the edge of the podium, her legs spread apart in an M-shaped shape, and the most secret part of the woman was fully displayed in front of the whole class.
Liu Qiang, come up and help the teacher explain. Teacher Chen called a male classmate up.
You use your hands to help push Li's private parts away from both sides. Li's hands have to support the table, so it is not convenient to do it yourself
Later, Teacher Chen pointed her slender finger at her mother's genitals and explained that, students, please see, the female external genitals are composed of mons pubis, labia and vagina, and the vagina. Here I would like to remind students that there are three holes with great differences in shape and size in the entire lower body of a woman.
Teacher Chen continued to explain: You see, the smaller hole on the top is called the urethra, which is the channel used by women to urinate. Some couples lack the necessary sexual knowledge and often mistakenly think that the urethra is the vagina, which can easily cause harm to women. There is a larger hole on the bottom. This is the vagina used by women to have sex and is also the smaller and tightly closed hole on the bottom of the birth canal for giving birth to children. It is generally a channel for defecation.
Teacher Chen, what do you mean generally? Isn’t the anus just used for defecation?
A classmate asked
Yes, some sexual behaviors use anus for sexual intercourse, which is a kind of obscene behavior that only very lewd women do.
Teacher Chen explained
So, how do men have sex with women?
This time I asked the question: the naughty classmate Wang
Although this problem is not the problem that needs to be solved in today's class, it is a very important knowledge for the students. So please ask Mother Li to give a one-time intercourse demonstration for the students?
Teacher Chen's decision received unanimous applause from the whole class
Is there any problem with Mother Li?
No
Mom shook her head and said, "But how do I demonstrate?"
Teacher Chen walked to his mother's side, handed the teaching stick to Liu Qiang and said: This is actually very simple. For example, the teaching stick in Liu Qiang's hand is a male penis. Look, inserting the penis into the vagina like this is sexual intercourse.
While explaining, Teacher Chen carefully directed Liu Qiang to gently insert the instruction stick in his hand into his mother's vagina.
Teacher Chen, the teaching stick in your hand is so hard that you can certainly insert it, but Li’s penis is soft and slim, so how can it be inserted?
The one who spoke was the same as Wang
Yes, Wang's observation can be said to be very careful. Therefore, before men and women have sex, in order to make the male penis fully erect, there is a foreplay, such as kissing, stroking and oral sex.
Teacher Chen walked to me, she reached out and held my cock, gently stroked it a few times, and then said: Look, is Li's penis bigger than just now?
I didn't expect that the best beautiful teacher in the school would actually help me shoot. When I was stimulated, my dick would naturally react.
Now please come up and touch Li's penis to actually experience how to help a man's penis fully erect
I could hardly believe that Teacher Chen actually wanted all the girls to come up and touch my cock. I looked at my mother a little at a loss. My mother was still sitting naked on the podium and smiling at me without saying anything.
Please line up and touch them one by one in sequence. When touching, please don’t use too much force. The male penis is sometimes very fragile.
Teacher Chen pointed out
So more than 20 female students in the class lined up in front of me. The first girl to come up was the Hu classmate. She touched my cock a little shyly and quickly retracted her hand, which made the girls behind laugh.
Then the girls who came up became much more courageous. They gently stroked my cock like Teacher Chen, and one of them touched my scrotum with his hands.
Then the boldest classmate Wang came up.
She first used gloves to get my cock a few times, then touched my scrotum. When I thought it was about to end, she squatted down and opened her mouth to hold my cock and sucked it a few times.
I looked at her in surprise and looked at Teacher Chen again. The teacher didn't say a word of accusation. It seemed that she did not object to Mr. Wang's bold move
I thought helplessly: I didn’t expect that my virginity would be destroyed by a girl’s mouth like this. It’s so miserable!
The next girl was timid and turned around after touching her, and the brave ones also imitated her classmate Wang and opened her mouth to hold my cock and suck it. Under the constant stimulation of so many female students, my cock quickly became very firm, and the glans was raised high and almost touched my belly.
Okay, students, please see, Li's penis has been fully erected in the foreplay just now. This is the role of foreplay. In fact, in addition to touching and oral sex, kissing is also very important. Let the teacher demonstrate kissing.
Teacher Chen walked up to me and said: Have you ever had any kissing experience?
I shook my head and said no
Then the teacher will guide you! Please open your mouth
Teacher Chen put her mouth over and pressed it against my mouth. Then, she put her tongue into my mouth.
To be honest, this is my first kiss
I was surprised to find that kissing was such a fun thing.
I held the teacher's tongue and sucked hard, then put my tongue into Teacher Chen's mouth.
Teacher Chen and I kissed for about three minutes, and she continued: Can Classmate Li’s penis be inserted into the vagina now?
Teacher Chen, can you let Li demonstrate the insertion?
Needless to say, the naughty classmate Wang is still talking
Although this kind of demonstration is inevitably suspected of pornography, mastering correct sexual knowledge is also very important and necessary for you in adolescence. Can Mother Li agree to have a one-time sexual intercourse demonstration with Li so that the students can have a chance to witness it and learn how to have sex with the opposite sex?
Does Teacher Chen really want my mother and I to demonstrate such sexual intercourse suspected of incest in front of more than 20 female classmates? I was so surprised that I opened my mouth wide and couldn't close it for a while.
However, what surprised me even more was my mother's attitude. She nodded without hesitation and said: As long as I can help these classmates, it's nothing to do with such demonstrations.
Since Mom Li agreed to have a sexual intercourse demonstration, OK, Li asked you to come here
Teacher Chen signaled me to walk to the front of the podium. Students, in order to observe more clearly, you can come to the edge of the podium, but please do not interfere with the sex between Li and his mother.
So more than 40 students in the class gathered together
I was both excited and nervous. Do I really want to have sex with my mom in front of so many students?
I held the base of my cock with my right hand, but the glans was dared to penetrate my mother's vagina but she didn't dare to insert it into it.
Teacher Chen gently pushed me behind me, so I pushed forward and pressed my glans against my mother's clitoris.
Mom said lightly, and her lower body slightly adjusted the angle, and my cock was inserted into my mother's vagina.
Wow! I've gone in!
A few female classmates shouted
good
Teacher Chen explained that this is sexual intercourse, Li's penis has been successfully inserted into Li's mother's vagina. Of course, this kind of insertion must be fully wet for the female vagina, otherwise the female vagina may feel uncomfortable due to injury.
So how can it be fully moist?
A girl asked
Men can caress women, or even help women with oral sex to make their vaginas fully wet. Classmate Li, try to help mothers with oral sex!
I looked at my mother, and she nodded at me with a rosy face. So I pulled out my cock, squatted down slightly, stuck out my tongue and licked my mother's vagina a few times.
Teacher Chen smiled and said: It seems that Li has not mastered the method of oral sex. You can lick your mother's labia and larvae back and forth first, and then tease your mother's clitoris with the tip of your tongue. The clitoris is the most sensitive sexual organ for women.
I did it as Teacher Chen taught me, and my mother screamed excitedly.
Teacher Chen, what does Li’s mom’s “Ah” mean?
Student Wang asked again
This means that Mother Li has already felt sexually excited. Usually, she is moaning. Look, there is already vaginal fluid flowing out of Mother Li’s vagina, right?
Really! A lot of vaginal fluid flowed out of Mother Li!
Teacher Chen, Mom Li’s vagina seems to be still squirming!
The students observed it very carefully! This kind of squirming means that Mother Li already wants her penis to be inserted into Li. You can try it with your tongue.
So I put my tongue into my mother's vagina and fucked it in and out, and my mother quickly made a moan again, AhAh...
How do you feel?
Teacher Chen asked me
Teacher Chen, it seems that the inside of my mother's vagina is wet and slippery, and there seems to be water seeping out of the inner wall of the vagina!
That's right
Teacher Chen said, this fully shows that your mother has urgently needed your penis to be inserted into her. Classmate Li, you can insert your penis into your mother's vagina now and thrust it back and forth.
I started having sex with my mother as Teacher Chen told me
Teacher Chen, where can I go to the deepest penis of Li?
I don't know who raised such an explosive question this time
Very good question!
Teacher Chen explained that during sexual intercourse, the deepest can be inserted into the uterus, but Li's penis is probably only seven inches long, while Li's mother's vagina should be nine inches deep, so Li's penis can only enter so much, so it cannot be reached into Li's mother's uterus.
Isn't this possible?
It was the girl who just said
Not bad. If a male classmate's penis is more than nine inches long, we can ask that classmate and Li's mother to demonstrate. However, today's sexual intercourse demonstration is not necessary to insert it into the uterus. Mom Li, do you agree with the male classmate having uterus intercourse with you?
OK!
Mom nodded and said
So which male classmate has a long penis? Come forward consciously!
As soon as Teacher Chen finished speaking, a male classmate stood up. When he stood up, his crotch was raised by the erect penis, so his body was obviously arched.
Seeing him like this, Teacher Chen couldn't help but smile and said: It's okay, Wen Xiong, it's all for everyone to learn better. Moreover, you are the class monitor, so you must take the lead for your classmates!
It turns out that this classmate is the class monitor, and his dick looks much bigger than mine, I thought to myself
Come on, take off your pants and walk to the teacher
Wen Xiong took off his pants and underwear in response, and saw a long cock popping out of his crotch, shaking up and down red. Several girls on the left and right looked at him, all of them blushed and lowered their heads.
Wenxiong walked to the podium wearing a white top and naked, facing everyone
Wenxiong, you can try inserting it!
Teacher Chen said
Wenxiong slowly inserted his cock, and his glans quickly pushed a soft flesh. Mom's moan, and her lower body trembled slightly.
I know that Wenxiong's glans has hit the mouth of his mother's cervix
Wenxiong looked at his mother, wondering if he wanted to go deeper and smiled at him. She blushed and said: Don’t move, let me do it!
So my mother erected her lower body slightly, Wenxiong's glans pushed open the soft flesh and entered her mother's uterus.
Wow! It's all inserted!
Mother Li’s vagina is really amazing! If it were me, I wonder if it could be done!
A few girls chattered and said
OK, Wenxiong and Li’s mother have successfully demonstrated the intercourse inserted into the uterus for us. This is a very successful demonstration. Do students have any questions?
Teacher Chen continued to ask
Teacher Chen
Classmate Wang stood up again. Didn’t you say that anal can also be used for sexual intercourse? Can you ask Mother Li to demonstrate for us?
This class will be over soon
Teacher Chen said: Mom Li, can you demonstrate anal sex in the following class?
Mom nodded and said: As long as it is helpful to the students' studies, I am very happy to serve.
Okay, Wenxiong can pull out your penis. This class will end here. If you have any questions, you can communicate in the next class.
Wenxiong was reluctant to pull out his cock. At this moment, due to long erection and various physical and mental stimulation, Wenxiong could no longer help ejaculate!
A stream of milky white and sticky semen ejaculated from his glans' urethra. Just as the glans had been halfway out of his mother's uterus, his thick semen ejaculated into his mother's vagina. Because the amount was too large, it was even squeezed out from the joint place.
My dearest mother was actually cummed by a junior!!
It's strange. Although I feel uncomfortable when I see my mother being cummed inside, I feel a strange feeling of pleasure in my heart.
Teacher Chen was also stunned for an accident. She didn't expect Wenxiong to ejaculate so suddenly. The classmates also looked at Wenxiong in a daze, as if he was a monster. My mother looked at me with a red face, then at the place where she and Wenxiong had sex without saying a word.
Teacher Chen, is this ejaculation?
A female classmate asked in a low voice
OK, this is ejaculation
Teacher Chen seems to have not completely recovered. She dipped some Wen Xiong's semen with her hands and said: Such a little semen can give birth to many children. If you want to enjoy the joy of sexual intercourse but don't want to hurt yourself, you must take effective contraceptive measures. In the next class, the teacher will tell the students how to use condoms.
I stood in front of the podium with great embarrassment, looking at my mother and Wenxiong. It was not until someone handed me a pack of tissues that I came to my senses.
It turned out to be the naughty classmate Wang! She looked at me sympathetically and said: You can't blame Wenxiong for this matter. Unless Wenxiong is not a normal man, who can guarantee that he won't ejaculate?
I thanked her and then started to wipe the semen flowing out of my mother's vaginal opening.
My mother asked me to wipe it gently until it was wiped clean. Then she closed her legs and got off the podium and put on her underwear and skirt again.
But as soon as I put on my clothes, my mother suddenly blushed and said to Wenxiong. Classmate Wenxiong, do you rarely slap in your hand? You have accumulated too much semen? When you ejaculate in the inside, the semen was too thick and stuck to my cervix, making me feel strange. You...you... Halfway through her speech, she blushed like mosquitoes and lowered her head
Can you help me get the semen out? Mom quickly said to Wenxiong.
After saying that, my mother turned her back, took her hands from under her skirt, pulled her underwear off, and put them in her hands, put them in her bag.
Then she held the podium and bent down, her buttocks raised to the squad leader.
From the side, my mother's seductive S-shaped curve is undoubtedly full of ease.
After seeing his mother's lustful movements, Wenxiong immediately excitedly put his finger into his mother's wet vagina and tucked it. However, after just a few tucks, his mother spoke again.
The fingers are too short to stretch inside, so you can use your penis to make it more efficient
After hearing this, Wenxiong immediately took out his cock and inserted it into his mother's pussy.
However, since it was his first time trying this position and he knew where the vaginal opening of this position was, he did not successfully insert his penis into his mother's vagina once, but accidentally slid open and poked her anus. Although he did not insert it at all, the impact still made his mother groan in pain: Uh!
Wenxiong heard his mother's moan and became playful. He teased and inserted his mother's cute dark red anus again. As expected, his mother groaned again.
What are you doing!
As he said that, his mother stretched out her hand to grab Wenxiong's penis and penetrated it into her vagina. However, it was probably because of different positions. This time, entering her mother's body made Wenxiong feel that her vagina was unprecedentedly tight. After a few thrusts, this time, Wenxiong quickly entered the situation.
Mom Li, have you removed the semen like this? He asked while thrusting his lower half hard.
I can't feel it, I just feel your penis hitting the ground inside
Mom resisted the excitement that should have made during sex, pretending to bury her head in her arms, as if she was just to remove the semen from the cervix, and did not enjoy the process at all.
Teacher Chen sighed when she saw her mother likes to eat and face, and said to the class monitor, Wenxiong, you can't get the innermost part of it like this. You must have a missionary position to insert your penis into the deepest part of a woman.
What is the missionary position? He was stunned
After hearing this, my mother turned her head over and her pretty face turned red with shame and said to him, "It's okay, let my aunt teach you."
So under the guidance of his mother, he picked up his mother, turned her over, let her lie on the desk, then carried her feet with her shoulders, lay on her body and sprinted hard, cleverly using waist strength, and indeed pushed every insertion to her mother's cervix.
Then he tried hard to circle his penis in his mother's body, and scraped her vaginal folds with the angled umbrella that intersected the glans and the coronal groove, thrusting hard
Finally, my mother no longer cared about her dignified image and shouted affectionately: Ah, Ah!...No...No!
I looked carefully and saw a trace of white thick vaginal fluid was grinding out where he and his mother's genitals were intercourse. As he pulled out, her mother's labia minora also turned out with her penis; and as he inserted it, her labia minora was inserted into her again.
At this moment, my mother suddenly hugged Wenxiong's neck tightly with her hands. I can't do it anymore. I'm going to have an orgasm. Ah... can't stand it anymore... let me go... Ah... you fuck you to death... fuck me to death
My mother's delicate body trembled and twitched wildly, her eyes closed, and a heat flow suddenly ejaculated from her lower body, hitting his glans. Wenxiong couldn't hold on at all. Mother Li, I'm going to ejaculate!
Both of them reached the peak of the explosion!
Then he pulled out his penis, and ejaculated on his mother's tender belly one by one, and then collapsed weakly on her sweaty body, hugging her mother tightly.
Ah, it seems to be cleaned. Mom gasped and made these syllables with her breath sounds.
After that, she got up and took out the underwear she had just taken off from her bag and wiped the vaginal fluid from her body. Then, when the others were not paying attention, she kneaded the underwear into a ball and stuffed it into Wenxiong's hand.
This extremely lustful sexual demonstration class ended like this. Actually, I guess it was not because the semen sticks to the cervix, but because she was not satisfied just now, but because she didn't dare to say it in front of so many people, she had to find an excuse to send Wenxiong another message.
I unexpectedly discovered that my mother was so beautiful and sexy, and I was also glad that I could have sex with my mother. I even began to look forward to the next sex demonstration class
I think mom and Fumixiong are looking forward to it too!
In June that year, the graduation exam had just ended. I was idle on campus, so I went to see my first-grade class teacher, Mr. Chen.
Teacher Chen has always taken good care of me, and I am very grateful to her
I sat in Teacher Chen's office for a while and chatted about the past. As I was talking about the human anatomy class she had recently. She said that the students she taught are very stupid when studying now. She asked me if I could help teach my juniors. Of course, I said no problem, because Teacher Chen is my favorite teacher and the best beauty teacher in the school.
Of course I have to do my best to ask for my help if such a beautiful teacher.
At that time, Teacher Chen was about 34 or 35 years old. Although he was already married, he was still beautiful and charming.
When she went to take our class, I was the class monitor. She never concealed her preference for me, and even caused jealousy among many boys in the class. Unfortunately, she only taught me for two years. When she was in the third grade, she changed a male teacher, and Teacher Chen returned to the first grade to take care of her current class.
I asked: What do you need me to do?
Teacher Chen smiled and said: Just to show your juniors and sisters.
Make a demonstration? What kind of demonstration?
I have never taken any human body demonstration class in my memory!
Teacher Chen smiled and said that he would know by then. When I saw that she didn't want to talk more, I stopped asking more questions.
Teacher Chen asked me to call my mother here again, so I could invite us to dinner after class, thank you for your help.
I didn't want Teacher Chen to invite her to dinner, but then I thought, can I take this opportunity to contact the teacher more! And I can also take the opportunity to invite her back! So I agreed.
My mother's name is Huang Meilian, and she was a doctor. She was 38 years old at the time, and was 1.68 meters tall. She had a measurement of 35, 24, 36. She had a standard model figure.
I was eighteen years old at that time, 1.78 meters tall, weighed 69 kilograms, and was a recognized handsome man.
The next morning, my mother and I came to Teacher Chen's office. Although her office is not big, it is a room for each person. Although the furnishings inside are simple, they are very clean.
Hello, Teacher Chen! This is my mother
I introduced them to both of them, and Teacher Chen couldn't help but praise him when he looked at my mother: Classmate Li, your mother is such a beautiful woman!
Mom smiled and said: Teacher Chen is also very beautiful!
Teacher Chen made tea for us and said: Please wait a moment, this class has not ended yet, the next one is my human anatomy class.
So my mother and I were drinking tea and chatting. Soon it was time to finish class. The classroom next door suddenly became lively. A few girls came to the door of Teacher Chen's office and looked in.
What do you think? Don’t you know that this is impolite?
Teacher Chen said with a straight face
A girl stretched out her tongue and said: Didn’t the teacher announce that the next class is a human body demonstration class? We want to see the nude model first.
Teacher Chen laughed: OK, you saw it too, are you satisfied?
The girl asked with a smile: There are two people here in the teacher. Which mannequin is today?
There are boys and girls in our class, and these two are nude models invited by the teacher!
At this time, the bell rang for class, and the girls rushed back to the classroom. Teacher Chen also stood up and said to me and my mother: Please come with me, two,
The classroom is next door when we entered the classroom with Teacher Chen, there were more than 40 students sitting inside, and the male-female ratio of the whole class is about 1:1
Teacher Chen asked my mother to sit down on a chair, and then asked me to stand in front of the podium.
Students, today we have the honor to invite senior Li Xiaoming and his mother Huang Meilian to be a nude model for everyone. Later, you can understand the difference between men and women through physical observation.
More than 40 students from the audience applauded together
I suddenly felt something was wrong, but now it's too late to regret
Classmate Li, please take off your clothes
Teacher Chen nodded at me
I took off my only sweatshirt with a stinging body, revealing my pretty muscular breasts
Please take off your pants, too
I glanced at Teacher Chen, and she looked at me firmly, so I had to take off the sports shorts again
There is also the pair of briefs that need to be taken off, Teacher Chen continued
If you take off, you will be naked? Standing naked on the podium in front of so many students in the class, is this what Teacher Chen calls a human body demonstration?
I took off my only underwear again, and my hands covered the hidden part of my lower body.
The whole class looked at me with more than 40 pairs of eyes. This was the first time I was so old that I took off naked in front of everyone, and more than 20 were women.
In order to teach in comparison with male body, I would like to ask Mrs. Li to come on stage to demonstrate female body for us. Can Mrs. Li?
When I was looking at Teacher Chen in surprise, my mother had already stood up from her seat. She walked to the front of the podium a little shyly and asked: Teacher Chen, do I want to take off my nakedness too?
Teacher Chen nodded and said: Not bad, does Mother Li agree?
Mom hesitated for a moment, and I thought she would not agree, but my mother looked at Teacher Chen and said: Well, in order for the students to learn knowledge, I am willing to be a demonstration of female entities.
After saying that, my mother took off her skirt. She was wearing a set of blue floral lace underwear. The underwear was designed very sexy. Except for a piece of paper-sized cloth in front that was embroidered with a few flowers, the rest were almost all transparent.
Mom seemed to have made up her mind. She took off her underwear without any hesitation and stood beside me openly
This is the first time I saw my mother naked, but I didn’t expect her figure to be so good!
Her breasts are big and firm, her abdomen is smooth and tight, her legs are long, and her buttocks are slightly upturned. She looks very tall and beautiful because she is wearing a pair of five-centimeter-high orange high heels.
Students, now there is a male entity and a female entity standing in front of you. I want to ask a student to tell you about their differences.
Teacher Chen tapped me with the instruction stick and said
I put my hands behind me awkwardly, and my penis hung softly due to tension, making me feel a little funny.
Several students in the audience raised their hands
Hu Yumei, please tell me
Teacher Chen pointed at a girl wearing glasses in front with a teaching stick.
The male has a prominent Adam's apple but the female does not, the female has plump breasts but the male does not. The hu classmate said
Is there any more? Teacher Chen asked
This... Classmate Hu suddenly turned red with his face. She shook her head and sat down.
Classmate Wang Yingying, what are the differences between male and female entities? Teacher Chen pointed to another girl and asked
This time, Wang, who stood up, was the most courageous girl who stood at the door of Teacher Chen’s office just after class. She had a medium figure and a pair of big, watery eyes, and looked very beautiful.
The biggest difference between men and women is their genitals
Student Wang said in a crisp voice, the male genitals have a protruding penis, while the female genitals are a hole that cannot be seen on the outside. There is also a hole in the male genitals, but the female does not.
Teacher Chen said in an approving tone: Student Wang’s analysis is very correct and good. The male external genitals are composed of a penis and a scrotum.
Teacher Chen pointed at the corresponding part of my lower body with a teaching stick and explained: As for women, the entire external genitals are relatively secret. Can you please sit on the podium and show your external genitals to your classmates?
OK
Mom agreed readily. She sat on the podium, her feet in high heels stepped on the edge of the podium, her legs spread apart in an M-shaped shape, and the most secret part of the woman was fully displayed in front of the whole class.
Liu Qiang, come up and help the teacher explain. Teacher Chen called a male classmate up.
You use your hands to help push Li's private parts away from both sides. Li's hands have to support the table, so it is not convenient to do it yourself
Later, Teacher Chen pointed her slender finger at her mother's genitals and explained that, students, please see, the female external genitals are composed of mons pubis, labia and vagina, and the vagina. Here I would like to remind students that there are three holes with great differences in shape and size in the entire lower body of a woman.
Teacher Chen continued to explain: You see, the smaller hole on the top is called the urethra, which is the channel used by women to urinate. Some couples lack the necessary sexual knowledge and often mistakenly think that the urethra is the vagina, which can easily cause harm to women. There is a larger hole on the bottom. This is the vagina used by women to have sex and is also the smaller and tightly closed hole on the bottom of the birth canal for giving birth to children. It is generally a channel for defecation.
Teacher Chen, what do you mean generally? Isn’t the anus just used for defecation?
A classmate asked
Yes, some sexual behaviors use anus for sexual intercourse, which is a kind of obscene behavior that only very lewd women do.
Teacher Chen explained
So, how do men have sex with women?
This time I asked the question: the naughty classmate Wang
Although this problem is not the problem that needs to be solved in today's class, it is a very important knowledge for the students. So please ask Mother Li to give a one-time intercourse demonstration for the students?
Teacher Chen's decision received unanimous applause from the whole class
Is there any problem with Mother Li?
No
Mom shook her head and said, "But how do I demonstrate?"
Teacher Chen walked to his mother's side, handed the teaching stick to Liu Qiang and said: This is actually very simple. For example, the teaching stick in Liu Qiang's hand is a male penis. Look, inserting the penis into the vagina like this is sexual intercourse.
While explaining, Teacher Chen carefully directed Liu Qiang to gently insert the instruction stick in his hand into his mother's vagina.
Teacher Chen, the teaching stick in your hand is so hard that you can certainly insert it, but Li’s penis is soft and slim, so how can it be inserted?
The one who spoke was the same as Wang
Yes, Wang's observation can be said to be very careful. Therefore, before men and women have sex, in order to make the male penis fully erect, there is a foreplay, such as kissing, stroking and oral sex.
Teacher Chen walked to me, she reached out and held my cock, gently stroked it a few times, and then said: Look, is Li's penis bigger than just now?
I didn't expect that the best beautiful teacher in the school would actually help me shoot. When I was stimulated, my dick would naturally react.
Now please come up and touch Li's penis to actually experience how to help a man's penis fully erect
I could hardly believe that Teacher Chen actually wanted all the girls to come up and touch my cock. I looked at my mother a little at a loss. My mother was still sitting naked on the podium and smiling at me without saying anything.
Please line up and touch them one by one in sequence. When touching, please don’t use too much force. The male penis is sometimes very fragile.
Teacher Chen pointed out
So more than 20 female students in the class lined up in front of me. The first girl to come up was the Hu classmate. She touched my cock a little shyly and quickly retracted her hand, which made the girls behind laugh.
Then the girls who came up became much more courageous. They gently stroked my cock like Teacher Chen, and one of them touched my scrotum with his hands.
Then the boldest classmate Wang came up.
She first used gloves to get my cock a few times, then touched my scrotum. When I thought it was about to end, she squatted down and opened her mouth to hold my cock and sucked it a few times.
I looked at her in surprise and looked at Teacher Chen again. The teacher didn't say a word of accusation. It seemed that she did not object to Mr. Wang's bold move
I thought helplessly: I didn’t expect that my virginity would be destroyed by a girl’s mouth like this. It’s so miserable!
The next girl was timid and turned around after touching her, and the brave ones also imitated her classmate Wang and opened her mouth to hold my cock and suck it. Under the constant stimulation of so many female students, my cock quickly became very firm, and the glans was raised high and almost touched my belly.
Okay, students, please see, Li's penis has been fully erected in the foreplay just now. This is the role of foreplay. In fact, in addition to touching and oral sex, kissing is also very important. Let the teacher demonstrate kissing.
Teacher Chen walked up to me and said: Have you ever had any kissing experience?
I shook my head and said no
Then the teacher will guide you! Please open your mouth
Teacher Chen put her mouth over and pressed it against my mouth. Then, she put her tongue into my mouth.
To be honest, this is my first kiss
I was surprised to find that kissing was such a fun thing.
I held the teacher's tongue and sucked hard, then put my tongue into Teacher Chen's mouth.
Teacher Chen and I kissed for about three minutes, and she continued: Can Classmate Li’s penis be inserted into the vagina now?
Teacher Chen, can you let Li demonstrate the insertion?
Needless to say, the naughty classmate Wang is still talking
Although this kind of demonstration is inevitably suspected of pornography, mastering correct sexual knowledge is also very important and necessary for you in adolescence. Can Mother Li agree to have a one-time sexual intercourse demonstration with Li so that the students can have a chance to witness it and learn how to have sex with the opposite sex?
Does Teacher Chen really want my mother and I to demonstrate such sexual intercourse suspected of incest in front of more than 20 female classmates? I was so surprised that I opened my mouth wide and couldn't close it for a while.
However, what surprised me even more was my mother's attitude. She nodded without hesitation and said: As long as I can help these classmates, it's nothing to do with such demonstrations.
Since Mom Li agreed to have a sexual intercourse demonstration, OK, Li asked you to come here
Teacher Chen signaled me to walk to the front of the podium. Students, in order to observe more clearly, you can come to the edge of the podium, but please do not interfere with the sex between Li and his mother.
So more than 40 students in the class gathered together
I was both excited and nervous. Do I really want to have sex with my mom in front of so many students?
I held the base of my cock with my right hand, but the glans was dared to penetrate my mother's vagina but she didn't dare to insert it into it.
Teacher Chen gently pushed me behind me, so I pushed forward and pressed my glans against my mother's clitoris.
Mom said lightly, and her lower body slightly adjusted the angle, and my cock was inserted into my mother's vagina.
Wow! I've gone in!
A few female classmates shouted
good
Teacher Chen explained that this is sexual intercourse, Li's penis has been successfully inserted into Li's mother's vagina. Of course, this kind of insertion must be fully wet for the female vagina, otherwise the female vagina may feel uncomfortable due to injury.
So how can it be fully moist?
A girl asked
Men can caress women, or even help women with oral sex to make their vaginas fully wet. Classmate Li, try to help mothers with oral sex!
I looked at my mother, and she nodded at me with a rosy face. So I pulled out my cock, squatted down slightly, stuck out my tongue and licked my mother's vagina a few times.
Teacher Chen smiled and said: It seems that Li has not mastered the method of oral sex. You can lick your mother's labia and larvae back and forth first, and then tease your mother's clitoris with the tip of your tongue. The clitoris is the most sensitive sexual organ for women.
I did it as Teacher Chen taught me, and my mother screamed excitedly.
Teacher Chen, what does Li’s mom’s “Ah” mean?
Student Wang asked again
This means that Mother Li has already felt sexually excited. Usually, she is moaning. Look, there is already vaginal fluid flowing out of Mother Li’s vagina, right?
Really! A lot of vaginal fluid flowed out of Mother Li!
Teacher Chen, Mom Li’s vagina seems to be still squirming!
The students observed it very carefully! This kind of squirming means that Mother Li already wants her penis to be inserted into Li. You can try it with your tongue.
So I put my tongue into my mother's vagina and fucked it in and out, and my mother quickly made a moan again, AhAh...
How do you feel?
Teacher Chen asked me
Teacher Chen, it seems that the inside of my mother's vagina is wet and slippery, and there seems to be water seeping out of the inner wall of the vagina!
That's right
Teacher Chen said, this fully shows that your mother has urgently needed your penis to be inserted into her. Classmate Li, you can insert your penis into your mother's vagina now and thrust it back and forth.
I started having sex with my mother as Teacher Chen told me
Teacher Chen, where can I go to the deepest penis of Li?
I don't know who raised such an explosive question this time
Very good question!
Teacher Chen explained that during sexual intercourse, the deepest can be inserted into the uterus, but Li's penis is probably only seven inches long, while Li's mother's vagina should be nine inches deep, so Li's penis can only enter so much, so it cannot be reached into Li's mother's uterus.
Isn't this possible?
It was the girl who just said
Not bad. If a male classmate's penis is more than nine inches long, we can ask that classmate and Li's mother to demonstrate. However, today's sexual intercourse demonstration is not necessary to insert it into the uterus. Mom Li, do you agree with the male classmate having uterus intercourse with you?
OK!
Mom nodded and said
So which male classmate has a long penis? Come forward consciously!
As soon as Teacher Chen finished speaking, a male classmate stood up. When he stood up, his crotch was raised by the erect penis, so his body was obviously arched.
Seeing him like this, Teacher Chen couldn't help but smile and said: It's okay, Wen Xiong, it's all for everyone to learn better. Moreover, you are the class monitor, so you must take the lead for your classmates!
It turns out that this classmate is the class monitor, and his dick looks much bigger than mine, I thought to myself
Come on, take off your pants and walk to the teacher
Wen Xiong took off his pants and underwear in response, and saw a long cock popping out of his crotch, shaking up and down red. Several girls on the left and right looked at him, all of them blushed and lowered their heads.
Wenxiong walked to the podium wearing a white top and naked, facing everyone
Wenxiong, you can try inserting it!
Teacher Chen said
Wenxiong slowly inserted his cock, and his glans quickly pushed a soft flesh. Mom's moan, and her lower body trembled slightly.
I know that Wenxiong's glans has hit the mouth of his mother's cervix
Wenxiong looked at his mother, wondering if he wanted to go deeper and smiled at him. She blushed and said: Don’t move, let me do it!
So my mother erected her lower body slightly, Wenxiong's glans pushed open the soft flesh and entered her mother's uterus.
Wow! It's all inserted!
Mother Li’s vagina is really amazing! If it were me, I wonder if it could be done!
A few girls chattered and said
OK, Wenxiong and Li’s mother have successfully demonstrated the intercourse inserted into the uterus for us. This is a very successful demonstration. Do students have any questions?
Teacher Chen continued to ask
Teacher Chen
Classmate Wang stood up again. Didn’t you say that anal can also be used for sexual intercourse? Can you ask Mother Li to demonstrate for us?
This class will be over soon
Teacher Chen said: Mom Li, can you demonstrate anal sex in the following class?
Mom nodded and said: As long as it is helpful to the students' studies, I am very happy to serve.
Okay, Wenxiong can pull out your penis. This class will end here. If you have any questions, you can communicate in the next class.
Wenxiong was reluctant to pull out his cock. At this moment, due to long erection and various physical and mental stimulation, Wenxiong could no longer help ejaculate!
A stream of milky white and sticky semen ejaculated from his glans' urethra. Just as the glans had been halfway out of his mother's uterus, his thick semen ejaculated into his mother's vagina. Because the amount was too large, it was even squeezed out from the joint place.
My dearest mother was actually cummed by a junior!!
It's strange. Although I feel uncomfortable when I see my mother being cummed inside, I feel a strange feeling of pleasure in my heart.
Teacher Chen was also stunned for an accident. She didn't expect Wenxiong to ejaculate so suddenly. The classmates also looked at Wenxiong in a daze, as if he was a monster. My mother looked at me with a red face, then at the place where she and Wenxiong had sex without saying a word.
Teacher Chen, is this ejaculation?
A female classmate asked in a low voice
OK, this is ejaculation
Teacher Chen seems to have not completely recovered. She dipped some Wen Xiong's semen with her hands and said: Such a little semen can give birth to many children. If you want to enjoy the joy of sexual intercourse but don't want to hurt yourself, you must take effective contraceptive measures. In the next class, the teacher will tell the students how to use condoms.
I stood in front of the podium with great embarrassment, looking at my mother and Wenxiong. It was not until someone handed me a pack of tissues that I came to my senses.
It turned out to be the naughty classmate Wang! She looked at me sympathetically and said: You can't blame Wenxiong for this matter. Unless Wenxiong is not a normal man, who can guarantee that he won't ejaculate?
I thanked her and then started to wipe the semen flowing out of my mother's vaginal opening.
My mother asked me to wipe it gently until it was wiped clean. Then she closed her legs and got off the podium and put on her underwear and skirt again.
But as soon as I put on my clothes, my mother suddenly blushed and said to Wenxiong. Classmate Wenxiong, do you rarely slap in your hand? You have accumulated too much semen? When you ejaculate in the inside, the semen was too thick and stuck to my cervix, making me feel strange. You...you... Halfway through her speech, she blushed like mosquitoes and lowered her head
Can you help me get the semen out? Mom quickly said to Wenxiong.
After saying that, my mother turned her back, took her hands from under her skirt, pulled her underwear off, and put them in her hands, put them in her bag.
Then she held the podium and bent down, her buttocks raised to the squad leader.
From the side, my mother's seductive S-shaped curve is undoubtedly full of ease.
After seeing his mother's lustful movements, Wenxiong immediately excitedly put his finger into his mother's wet vagina and tucked it. However, after just a few tucks, his mother spoke again.
The fingers are too short to stretch inside, so you can use your penis to make it more efficient
After hearing this, Wenxiong immediately took out his cock and inserted it into his mother's pussy.
However, since it was his first time trying this position and he knew where the vaginal opening of this position was, he did not successfully insert his penis into his mother's vagina once, but accidentally slid open and poked her anus. Although he did not insert it at all, the impact still made his mother groan in pain: Uh!
Wenxiong heard his mother's moan and became playful. He teased and inserted his mother's cute dark red anus again. As expected, his mother groaned again.
What are you doing!
As he said that, his mother stretched out her hand to grab Wenxiong's penis and penetrated it into her vagina. However, it was probably because of different positions. This time, entering her mother's body made Wenxiong feel that her vagina was unprecedentedly tight. After a few thrusts, this time, Wenxiong quickly entered the situation.
Mom Li, have you removed the semen like this? He asked while thrusting his lower half hard.
I can't feel it, I just feel your penis hitting the ground inside
Mom resisted the excitement that should have made during sex, pretending to bury her head in her arms, as if she was just to remove the semen from the cervix, and did not enjoy the process at all.
Teacher Chen sighed when she saw her mother likes to eat and face, and said to the class monitor, Wenxiong, you can't get the innermost part of it like this. You must have a missionary position to insert your penis into the deepest part of a woman.
What is the missionary position? He was stunned
After hearing this, my mother turned her head over and her pretty face turned red with shame and said to him, "It's okay, let my aunt teach you."
So under the guidance of his mother, he picked up his mother, turned her over, let her lie on the desk, then carried her feet with her shoulders, lay on her body and sprinted hard, cleverly using waist strength, and indeed pushed every insertion to her mother's cervix.
Then he tried hard to circle his penis in his mother's body, and scraped her vaginal folds with the angled umbrella that intersected the glans and the coronal groove, thrusting hard
Finally, my mother no longer cared about her dignified image and shouted affectionately: Ah, Ah!...No...No!
I looked carefully and saw a trace of white thick vaginal fluid was grinding out where he and his mother's genitals were intercourse. As he pulled out, her mother's labia minora also turned out with her penis; and as he inserted it, her labia minora was inserted into her again.
At this moment, my mother suddenly hugged Wenxiong's neck tightly with her hands. I can't do it anymore. I'm going to have an orgasm. Ah... can't stand it anymore... let me go... Ah... you fuck you to death... fuck me to death
My mother's delicate body trembled and twitched wildly, her eyes closed, and a heat flow suddenly ejaculated from her lower body, hitting his glans. Wenxiong couldn't hold on at all. Mother Li, I'm going to ejaculate!
Both of them reached the peak of the explosion!
Then he pulled out his penis, and ejaculated on his mother's tender belly one by one, and then collapsed weakly on her sweaty body, hugging her mother tightly.
Ah, it seems to be cleaned. Mom gasped and made these syllables with her breath sounds.
After that, she got up and took out the underwear she had just taken off from her bag and wiped the vaginal fluid from her body. Then, when the others were not paying attention, she kneaded the underwear into a ball and stuffed it into Wenxiong's hand.
This extremely lustful sexual demonstration class ended like this. Actually, I guess it was not because the semen sticks to the cervix, but because she was not satisfied just now, but because she didn't dare to say it in front of so many people, she had to find an excuse to send Wenxiong another message.
I unexpectedly discovered that my mother was so beautiful and sexy, and I was also glad that I could have sex with my mother. I even began to look forward to the next sex demonstration class
I think mom and Fumixiong are looking forward to it too!
