Chapter 18 Mother’s sperm donation teaching (II)

I want you to have sex in stockings, okay?

Ah! That's how Ah! Of course

Mom smiled slightly and said to the female nurses: When you are fertilized, any request made by the other party is reasonable, you must satisfy it as much as possible.

My mother took off her underwear, so she was wearing only a pair of flesh-colored stockings. Although she was forty years old, her figure was still very good. Her legs were round and slender, her buttocks were slightly raised, and her breasts on her chest were slightly drooping, but they were very large and full. A deep cleavage in the middle attracted imagination.

Mom climbed onto the bed and rode on my thighs. She signaled four nurses to stand on both sides of the bed, then held my cock with her right hand, separated her labia with her left hand, and leaned over and gently wrapped my glans and sank down. My whole cock was penetrated into the depths of my mother's vagina.

Yingying, you go get an test tube

OK

When Yingying went to get the test tube, her mother sat on my dick and didn't move

For you, Director Huang

My mother took the test tube and sat on my cock to teach four nurses: Look, the penis of the sperm donor has been inserted into my body. Although it seems to be a simple sexual intercourse, we must grasp the right measure. As fertilized people, we must not just seek temporary happiness, but let the sperm donor ejaculate as soon as possible, because every time we have to face five sperm donors. If we reach orgasm too quickly, the subsequent work will not be carried out. Remember?

Remember, the four nurses answered in unison

My mother gently stroked it a few times to keep my cock erection. She continued: After the sperm donor ejaculates, she must take off the condom as soon as possible, put the semen into this test tube, and then put the label on it.

The female nurses listened very seriously

Okay, who will come up first now? Mom said as she got off me, the vaginal fluid in her vagina stuck to my cock, shining like a layer of cream

Seeing that everyone was not making a sound, Yingying stood up and said: I'll do it first!

So Yingying quickly took off her clothes. She was about to climb onto the bed, but her mother stopped her. You are not married yet, put on the condom before doing it. It's not enough to avoid business accidents.

Director Huang, there is no need to do it. I just stroking it for a few strokes and I won’t get ejaculation.

No, you should develop good habits in this way so that you won’t be negligent. Do you understand?

Yingying stretched out her tongue and said yes, then went to the shelf to get a condom and gently tear it open the outer packaging. She took out the condom and helped me put it on.

Yingying climbed onto the bed and asked me to lie on her body. So we changed positions. I knelt between her legs and inserted my cock into her vagina.

It feels very uncomfortable to do with a condom on my cock. I just fucked Yingying out of bed after a few symbolic times.

The second person to go to bed was Nurse Xu. She was thin and her pubic hair was repaired. She looked quite sexy. She also asked me to lie on her and fuck her.

When my glans thrust in, I found that it was tight inside her, so my mother got some lubricant and applied it to my cock condom. This time I finally inserted it smoothly

Oh, so big! Nurse Xu moaned

Then do you like it? Yingying asked with a smile

Nurse Xu nodded with a blushing face and said: Of course, the bigger the dick, the more comfortable it feels!

OK, Dr. Li, you can make fun of her and make her feel good!

Yingying, at this time my mother spoke, you forgot again, we fertilized people cannot just think about reaching orgasm, we must try every means to make the other person ejaculate.

When my mother taught Yingying, I took the opportunity to fuck her hard, which made Nurse Xu confused and raised her legs and screamed.

OK, Nurse Xu can come down, Mom said

Nurse Xu reluctantly got out of the bed, and it was obvious that she was a little annoyed because she had not reached orgasm!

Nurse Yu, it's your turn, mom said

Nurse Yu looked at me shyly, but she still took off the clothes. Her pubic hair on her lower body was very thick, but her skin was very white.

Nurse Yu rode on me, she spitted on her hands, wiped it down, and then sat down with my cock

Have you all gone in? Yingying asked

Well, Nurse Yu nodded, and her delicate body stroking it together

Okay, let’s get here! Mom asked Nurse Yu to stop and then said to Nurse Zhang: You are not married yet, so you don’t need to do it anymore

Nurse Zhang blushed and said softly: Director Huang, Yingying is not married either. Since she has done it, I want to give it a try.

Then have you ever broken the ground? Mom asked

Nurse Zhang's face turned redder, and she said: What does this matter?

You can't be still a virgin, right? Yingying smiled

Yes, Nurse Zhang's voice was even smaller. I don't know if she was sure of Yingying's words, or would she admit that she was a virgin.

Are you really still a virgin? Mom was also surprised. After all, virgins have become rare animals in this era.

Yes, Nurse Zhang nodded and said

That would be even worse, mom said

She wants to try it, let him try it

Yingying said

I know she wants to help me, because she was already broken before dating me. Although I have fucked many women, none of them are virgins yet!

Mom looked at Yingying, then looked at me, and then said: Nurse Zhang, the destruction is not a trivial matter, you must think clearly

Nurse Zhang was playing with a strand of hair at a loss, and because she was nervous, she stuttered a little: Director Huang said, ~ To be honest, ~ Virginity is not good for me, when I was studying, my classmates in the class joked about me! Donating ~ Since donating sperm is an important task in our department, I can't stay out of it.

Well, Yingying, go and get some lubricant to apply to her. Mom told me, Nurse Zhang, when I do it later, you have to take it slowly. There will be a little pain at the beginning, and you will endure it and it will pass.

Yes, thank you Director Huang

After Nurse Zhang applied lubricant, she shyly climbed onto the bed. My mother asked her to lie on the bed, so I would do it.

I have never fucked a virgin pussy, so I was naturally a little nervous. I knelt between Nurse Zhang's legs and pressed my glans against the opening of her vagina. Her pubic hair was not too much, and it grew sparsely on the periphery of the labia majora. The color of the labia minora was pink.

I pushed my glans and just went in a little while. Nurse Zhang shouted in pain, so I had to stop and look at my mother

Don't worry, Mom looked at me with a smile and said, "You can go in with a little force."

I thrust hard, and the glans finally entered, but Nurse Zhang screamed in pain, and I stopped again

You'd better stop doing it! I said that although I didn't give her some regrets, I couldn't bear it when I saw her in pain so much, so I felt so sorry for her.

You do it, I can bear it. She tried hard to separate her labia and bit her lower lip and said

I thought to myself: It’s better to have a short pain than long pain, so I’ll just do it hard.

So I gritted my teeth and poked hard. With Nurse Zhang's scream, a stream of bright red blood flowed out of her vagina.

My cock was in a dilemma. I looked at my mother at a loss. Seeing that my mother gave me encouraging eyes, I had the courage again. I exerted force again and finally pushed most of my cock in.

Nurse Zhang was already sweating profusely in pain!

OK, please help her touch her breasts, she will get used to it for a little while, Mom said

I pressed and rubbed Nurse Zhang's pair of breasts, lowered my head and sucked her nipples gently, and my cock was carefully thrusting in her vagina.

Oh~Ah~

Nurse Zhang moaned

How about it, do you feel it? Yingying asked her with concern

Well, Nurse Zhang nodded

I looked at my mother again and said: Is it OK?

Mom smiled and said: This is her first time. You must let her reach orgasm, otherwise she will have psychological shadows in the future.

I was just so eager, so I continued to fuck her. Soon, Nurse Zhang was screaming and kept screaming by me.

AhAh~It's so cool~

My mother, Yingying and the others laughed and I fucked her for a while, and then my mother stopped crying. OK, it will be swollen if I fuck her again!

In this way, I fucked them all in just over half an hour

Director Huang, what should I do if Dr. Li has not ejaculated yet? Yingying asked

Today is just a training class, it doesn't matter if you don't have ejaculation

However, if we don’t ejaculate, we won’t learn how to collect semen Ah! Yingying continued: Director Huang, can you give him a complete sperm donation demonstration?

Oh well!

As my mother said, she climbed onto the bed again. She pulled off the condom on my dick and handed it to Yingying, saying: I can't use this, you go and throw it away.

My cock got rid of the constraints of the condom and felt a sense of comfort. My mother rode on me and quickly put her vagina on her vagina and started fucking me.

Because there are bystanders, I dare not be too presumptuous, but just passively endured my mother's tricks.

My mother seemed to be more open than me. She picked up my hand and placed it on her breasts. So I kneaded my mother's breasts and my lower body catered to her tricks.

At this time, Yingying spoke beside the bed: Let me tell you a secret: Dr. Li is my fiancé! Brother Li, do you think it is Ah?

The other three nurses looked at Yingying in surprise, and the youngest nurse Zhang said: No wonder you look very natural! Did you intend to let him sign up for this sperm donation training?

Not bad, I have a bigger secret, do you want to know?

Mom looked at Yingying with a little worried. Of course I know what my mother is worried about

I said: Yingying, don’t talk nonsense!

Princess Yingying smiled and said: What are you afraid of? Anyway, they will know sooner or later. Let me tell you. Director Huang is Brother Li's biological mother, and my future mother-in-law.

The nurses all stared at us, mother and son with wide eyes. My mother was blushing and sitting on my cock. She was not moving, nor was she moving, and she was so embarrassed that she didn't know what to do.

Then isn't they incest like this? Nurse Xu said

Don’t talk nonsense, Yingying said, today is just a training class. Brother Li and his mother are just doing sperm donation demonstrations for everyone. How can it be said to be incest?

But how can mother have sex with her son? Nurse Yu said

Why can't it be possible? Brother Li was born from his mother's vagina. Now, what's wrong with just inserting a part of his cock into it?

It seems that there is some reason for you to say this. Nurse Zhang blushed and said: But according to what you say, both mother and son can have sex!

Of course, there must be a reason. Yingying said: I asked them to have sex today, because if Brother Li doesn’t come to sign up, wouldn’t my mother-in-law want to let another man fuck her?

This is true. All three nurses think that Yingying's words are not unreasonable.

Seeing that my mother looked embarrassed, I pressed her under her body, straightened her lower body, and thrust her dick quickly.

My mother was so excited that she was fucked by me soon. She forced herself to do it first, but finally couldn't help but moan: AhAh~ Oh~ Mom can't stand it anymore~Ah~

I thrust hard again, and my mother quickly reached orgasm with a scream!

Oh~Ah~

My mother's vagina twitched, and her whole body fell down and I fucked her dozens of times, and her glans numb and ejaculated.

Yingying, get the test tube

My mother told Yingying to bring the test tube. She signaled me to pull out my cock and then put the test tube mouth at the vaginal opening. At the same time, she did not forget to educate her subordinates: Look, this is how the other party collects semen after ejaculation!

Director Huang and Nurse Xu said: Your son has ejaculated so much semen in your vagina, will you get pregnant because of this?

Mom blushed and said: No, because I put on a ring after giving birth to him, otherwise I wouldn't let him cum inside.

After my mother and I got off the bed, my mother told everyone to put on their clothes. She said: Today's class is over. Do you have any questions?

No more, the four female nurses said in unison

An unforgettable sperm donation training class ended like this. Not only did I fuck five women, including my mother, but I also fucked a virgin for the first time
