Chapter 3 Second Sex Demonstration Class

Back home, I tried to break the mother-son relationship between me and my mother

But I quickly found that this didn't work

Whenever I try to get close to my mother, my mother will stop me with her unwavering eyes. I feel very frustrated and have to look forward to the next sexual demonstration class.

A week later, Teacher Chen sent an invitation to me and my mother.

We came to her office. This time she did not ask me to go to another room to change clothes, but took us mother and son to the next classroom

The moment we entered, the female students in the classroom clapped neatly, and it seemed that they were looking forward to this sexual intercourse demonstration class.

Teacher Chen walked to the podium and announced in public: We will learn two contents in this class today: one is how to use condoms correctly, which is very important to you; the other is what common postures are there for sexual intercourse. In order to facilitate students to observe nearby, I would like to ask students to move their desks around.

So all the female classmates moved their desks to the surroundings of the classroom. Teacher Chen asked my mother and I to walk to the open space in the middle of the classroom.

Mom Li, classmate Li, you can take off your clothes now. Teacher Chen said

We quickly took off all our clothes

Although this is the second time I have shown my naked body in front of so many female students, I am still a little uncomfortable. My mother seems to be more calm than me.

Now let's learn how to use condoms correctly

Teacher Chen said as she took out a small plastic bag from her pocket. She gently tore open the bag, took out the things inside and showed them to the students and said: Look, this is a condom. Does anyone know how to wear a condom?

At this time, a female classmate stood up and said: Can I give it a try?

The person who spoke was the somewhat cramped student Wang

Teacher Chen said: Yes

Classmate Wang took the condom from Teacher Chen's hand and walked in front of me. She put the opening of the condom on my glans, and then gently stroked it down.

Since my penis was already erect, she quickly put on a condom for me

Teacher, am I doing it right?

Teacher Chen nodded and said: It is already very good that you can do this, but before wearing a condom, the male penis should be fully moistened, otherwise the male will lose sexual desire due to pain. Mother Li, can you ask you to demonstrate to your classmates?

Mom nodded and said: OK

So my mother walked up to me. She didn't bent down like Mr. Wang just now, but squatted down in front of me. She gently took off the condom for me, then opened her mouth and took my penis and sucked it a few times, then spit it out and helped me put on the condom again.

Did the students see it? Teacher Chen said, Mother Li’s demonstration just now was very good, of course there are many ways to make the penis wet, and oral sex is just one of them.

At this time, a classmate asked: Teacher Chen, are there any other ways to wear condoms?

Teacher Chen said: Good question, can you wear condoms for men and use your mouth to wear mother Li?

Mom shook her head and said: No

OK, let’s demonstrate how to wear condoms with your mouth

Teacher Chen also squatted down in front of me like her mother. She took off the condom, stuck out her tongue and licked my cock for a while, and then sucked it in her mouth. Classmates, now Li's penis is fully wet. Next, you should pay attention to how the teacher uses his mouth to help men wear condoms.

After saying that, Teacher Chen put the condom in his hand into his mouth, left the opening of the condom outside his mouth, pressed the opening on my glans, and swallowed the penis bit by bit. When she spit out my cock, the condom was already put on.

A warm applause suddenly sounded in class

Next is a sex match with a condom. Teacher Chen signaled me to lie on the floor of the classroom. Because the floor was very cold, the teacher suggested using the clothes that my mother and I took off to cushion underneath.

After I lay down, Teacher Chen nodded to her mother, but she didn't shy. She stepped over my body and squatted down slowly. She held the base of my penis with one hand, gently stroked it a few times, and reached the other hand to the middle of her legs to spread the labia and the malaria, put the vaginal opening on my glans and sat down gently.

The whole class of female students gathered around at this time. They watched seriously, and there were still people talking in a low voice.

Really got in

Will wearing condoms affect the pleasure?

Teacher Chen obviously heard their comments, and she said with a smile: Wearing condoms will certainly affect pleasure, but in order to ensure safety, wearing condoms is still necessary. If you don’t want to have children, you must insist on letting men wear condoms when having sex with them.

But you can also take birth control pills! The person who spoke was that classmate Wang

Do you understand? Teacher Chen said in a serious tone that taking too much medicine is not good for the body, especially for adolescent girls like you, you should avoid taking medicine.

When Teacher Chen educated the students, my mother sat on my cock and looked very embarrassed. I wonder if she was going to get off or continue to sit down.

Mom Li can come down. The teacher said that next is a demonstration of sexual posture

After my mother got off me, Teacher Chen took off the condom that was put on my penis and said: Students, Mom Li has been on the ring, so you don’t need to wear condoms for the next sexual demonstration. Therefore, you can see the intimate contact between their mother and son’s sexual organs. You must observe carefully later. If you have any questions, you can ask them.

At this time, the classmate Wang suddenly spoke: Teacher Chen, why do you have to find Mom Li to be the partner of Li’s sexual intercourse? Isn’t mother-son incest the biggest taboo for incest?

I saw my mother's face turn red all of a sudden

Student Wang, you should know that what we are doing now is a teaching demonstration, not really having sex. Since Li is underage, the teacher asked him to do the demonstration and had to win the consent of his parents. If Li's mother is not invited to be her son's sex partner, then who should I invite?

Teacher Chen can do it too!

It is not impossible for the teacher to be a partner of Li's sexual intercourse, but firstly, he also needs to obtain the consent of his mother, and secondly, the teacher also needs to be a tour guide. It is inconvenient. The teacher originally wanted to hire a call girl from outside, but he was afraid that Li's mother would not agree.

Teacher Chen nodded to his mother and continued: Actually, the son's body was born from his mother's vagina. After the son became an adult, he would use his vagina to teach his son how to have sex with his vagina. What's wrong with this?

So what is mother-son incest? Someone asked

Unusual sexual behavior between mother and son is mother and son incest

Then what is abnormal sexual behavior? Or did the classmate ask just now

Teacher Chen pondered for a moment and said: For example, if the mother and son who were carrying their fathers, and if the mother and son had a child who had a mess of their generation after having sex, it was the mother and son incest.

Does Teacher Chen mean that as long as you don’t have children and don’t carry your relatives at home, it’s not an incest? This time it’s that classmate Wang again

Teacher Chen said: That should be

Student Wang continued: Are dad and daughter the same?

Teacher Chen said in a serious tone: The sexual behavior between father and daughter is not as simple as between mother and son. Because the hymen is intact before the virgin is broken. If the girl loses her virginity too early, if the husband cares about her virginity, it may bring about unhappiness in the marriage.

So, mother-son sex only requires the consent of the father, while father-female sex requires not only the consent of the mother, but also the consent of the husband? Isn’t this unfair?

There are many unfair things in this world. Our class is not used to discuss ethics. Please continue to demonstrate sexual intercourse for us.

Next, my mother and I demonstrated several sexual positions in front of more than 30 female classmates in the class, and even demonstrated anal sex.

To be honest, my mother and I don’t like anal sex. When I stuffed my cock into my anus, my mother was so painful that she trembled all over, which made me feel very distressed.

When the get out of class was about to end, Teacher Chen suddenly announced: Students, can I ask Li and his mother to have a complete sex for us?

A cheers suddenly sounded in the classroom

I looked at my mother, but she had already set up her pose and just waited for me to go up and fuck her

I inserted my dick from behind my mother. This time it was no longer a demonstration of how to use the dragonfly to flash water, but a real gun and ammunition fucked her.

In order to increase sexual stimulation to my mother, I was thrusting my cock while stroking my mother's breasts, thighs and buttocks with both hands while stroking my mother's breasts, thighs and buttocks with both hands.

Mom soon got into the state. She couldn't help but scream loudly, and her vagina became more and more slippery. Psychic fluid kept seeping out of the junction of our mother and son's sexual organs, wetting the floor of the classroom

Teacher Chen, what's going on with so much water coming out of Mother Li? A classmate asked

Teacher Chen explained: These are all vaginal fluids. When men and women experience pleasure, vaginal fluids will flow out. Their function is to avoid damage to the vagina due to violent thrusting. Look, Mom Li is already on the verge of orgasm.

At this moment, I suddenly felt my mother's vagina twitch violently, and a stream of vaginal fluid sprayed on my glans, and then my mother's delicate body kept trembling.

AhAh~ Mom made a lewd sound

Students, please see, this is a typical orgasm symptom! Li’s mother is probably in orgasm now, this is the happiest moment for a woman.

Teacher Chen explained and said to me: Student Li’s performance today is really great. It would be even better if he could complete ejaculation in your mother’s body.

Before Teacher Chen finished speaking, I started ejaculation

I hugged my mother's legs tightly with both hands, and injected hot semen into the depths of my mother's vagina.

I finally sprinted a few times and then fell on my mother's back and stopped moving

Wow, Li ejaculated!

You see, he is sweating a lot!

The female classmates around me were talking about this, Teacher Chen told me to pull out my penis and let the students watch my mother's vagina being ejaculated.

Look, these milky white liquids that flow out are men's semen. When Li's father ejaculated in Li's vagina, he combined with the eggs discharged from Li's body and gave birth to him.

Will Li ejaculate in his mother's vagina, and will he have a baby? Someone asked

No, Teacher Chen said: Because Mom Li has already been on the ring

Then my mother squatted down and let the semen flow out from her vagina, then got up and put on her clothes.

This long-awaited sexual demonstration class ended like this. I fucked my biological mother's slutty pussy as I wished, and even ejaculated incest semen in her vagina.
