Rong Yu was hugged between Zheng Mingchi's thighs, watching Zheng Mingchi turn off the video with a numb expression, then opened the browser, and entered word by word in the input box - male, x organ composition and principle.

Rong Yu: "..."

With a stiff face, Rong Yu sincerely begged: "Zheng Mingchi, I will really listen carefully, can you let me down?"

Zheng Mingchi also asked seriously: "Why?"

Rong Yu: "...I feel so uncomfortable for you!"

Zheng Mingchi patted Rong Yu's head, and comforted him: "It's okay, don't move, it will disappear by itself in a while."

Rong Yu: "..."

Zheng Mingchi: "I'll tell you later why it disappears by itself."

Rong Yu: "..." Thank you, I don't want to know the principle at all.

However, passive confrontation is useless. Zheng Mingchi seems to have made up his mind today to explain to Rong Yuzai this important matter that is seriously related to his physical problems. He searched for a long time among the searched web pages, and finally chose I took a picture and opened it.

Zheng Mingchi lowered his head, leaned into Rong Yu's ear and asked softly, "Can you see clearly?"

Rong Yu: "...very clear."

Zheng Mingchi enlarged the picture again.

Rong Yu: "..."

Ma Da, what's so good about the structure that is exactly the same as my own in the picture, I have to zoom in to see it!

It is probably for the audience to see more clearly. The thing painted on the picture is the state after the blood is congested. It stands upright stiffly. It is very thick and looks full of danger.

Then, very academically, arrows pointing outwards were added to the side, and text descriptions were added.

For example, there is an arrow next to the two testicles.

Scientific name: Gaowan.

The more Rong Yu looked at it, the more he felt that the things on the picture were full of danger. He swallowed, and whispered to Zheng Mingchi in an unnatural voice: "I, I don't want to hear it..."

Zheng Mingchi rejected Rong Yu's request coldly and ruthlessly: "You said just now that you should listen carefully, so why don't you count your words?"

Rong Yu: "..."

But he didn't want to listen to this kind of indecent class either——Rong Yu wrinkled his face, and sat pitifully on Zheng Mingchi's lap, not daring to move.

"Okay, let's finish soon, okay?"

Zheng Mingchi put his arms around Rong Yu's waist, and said very gently, "Don't worry, x education is what should be taught to students in elementary and junior high schools, and what I'm telling you now is not something you can't say, don't be shy ,Um?"

In a trance, Rong Yu felt that there was a bit of sincerity in Zheng Mingchi's tone, and he didn't notice that he was tightly hugged in his arms, but tried hard to think about it, and asked back: "Really, Really?"

Zheng Mingchi comforted: "Of course, don't be afraid, other students in the class know about it too."

It's just that what I know is the knowledge of sexual life between men and women.

Of course Zheng Mingchi would not tell Rong Yu this sentence, he moved the mouse after fooling the silly child in his arms, and the arrow just happened to be placed on the two balls.

He leaned next to Rong Yu's ear, and said very academically: "Look here. Do you know these two words? This is a place to store liquid. The longer you hold it, the more stock there will be."

Rong Yu's face was so red that he was about to burn, he covered his face with his hands, trying to cool himself down.

Zheng Mingchi was still beside him and said reluctantly: "Do you remember?"

Rong Yu almost cried out of anger, he moved his body almost subconsciously: "I know, I know, I know! There! There is still a place where I can get hard! I don't need to listen to this! I'm going to study now!"

Zheng Mingchi didn't interrupt Rong Yu's words, he waited quietly and patiently for him to finish speaking, and then said "um" slowly: "It seems that we Yuyu know quite a lot..."

Rong Yu's face turned even redder. He opened his mouth and fumbled for a long time without choking out a word.

"Okay, then you have passed this one."

Zheng Mingchi turned off the picture with a big wave of his hand, and when Rong Yu let out a long sigh of relief, thinking that today's extra-curricular tutoring was over, Zheng Mingchi opened another picture.

Rong Yu glanced subconsciously, then was slightly taken aback.

This picture is completely different from the one just now, at least without the rattling organs, instead it looks like a picture of the internal structure.

It is also pointed outward with an arrow, and then marked.

Rong Yu stared blankly, then heard Zheng Mingchi ask him: "New question, do you know what this picture is about?"

Rong Yu shook his head, trying to change the subject: "Didn't it pass today?"

Zheng Mingchi shook his head, then rested his chin on Rong Yu's shoulder, lowered his voice and coaxed: "Don't play tricks, I just said that the picture was passed, but this one is not."

Rong Yu sniffed aggrievedly, and retorted: "Well, if there are always pictures, it will never end!"

Zheng Mingchi smiled: "Don't worry, this is the last picture."

Rong Yu felt that the thing holding him under his body was getting harder and harder, and he confirmed it with Zheng Mingchi again tremblingly: "It's really the last picture, huh?"

"Really, I'm not like you, I always act like a baby every day." Zheng Mingchi teased Rong Yu with a smile.

Rong Yu puffed her cheeks and said angrily, "I never act like a baby!"

Zheng Mingchi lowered his head to look at the cute hair on the top of Rongyu's head, and said quite generously: "Okay, Yuyu never acts like a baby. Can you learn from the pictures now?"

Rong Yu was extremely awkward: "This is still learning."

"Of course forget it." Zheng Mingchi chuckled twice, "The short videos you got from Tao Hua are all considered learning materials, so how come this is not considered learning?"

Rong Yu: "..."

How angry, how could he still remember!

Rong Yu bit the bullet and looked at it for a long time. There was no other description on this picture except for a few notes in Chinese characters.

A diagram of the structure of a section of the intestine.

Zheng Mingchi hugged him and asked, "Do you understand?"

Rong Yu had already decided to break the jar, so he sat up straighter and said with a straight face, "No, I don't know you. Tell me, I'm going to sleep after I finish!"

Zheng Mingchi saw that Rong Yu was about to turn himself into a puffer fish again, so he stopped embarrassing him, moved the mouse, and slid the arrow on the picture: "This is a diagram of the physiological structure of the male intestine."

After thinking about it, Zheng Mingchi added another sentence: "This is the place where men have sexual relations."

Rong Yu subconsciously said: "This is not for—!"

Almost immediately, he recalled the action he had seen on that little video before, and his expression became extremely complicated for a moment.

"Yes, but as long as the measures are taken, there will be no problem at all."

Zheng Mingchi touched Rongyu's head, his voice was low and coaxing, he moved the mouse, and put the arrow on a small raised point, "The receiving side between men, through the friction of this point, The most intense pleasure can be obtained."

Then, Zheng Mingchi's scorching breath came to Rong Yu's ear, and he said in a very low and gentle voice, "It's also possible that it will be more comfortable than between a man and a woman."

Rong Yu, who had been completely refreshed, stared at the round eyes, and looked at the picture on the computer, and did not speak for a long time.

Zheng Mingchi patted Rong Yu's shoulder lightly, hugged him off his body, and then pinched Rong Yu's nose: "Okay, are you scared?"

Rong Yu looked up at Zheng Mingchi in a daze.

Zheng Mingchi was amused by Rong Yu's silly appearance, couldn't help stretching out his hands to tease him, then pulled his clothes, and said very normally: "Many homosexuals are born with inclinations, and have nothing to do with the day after tomorrow."

He thought about it, and said to Yudao seriously, "In this world, every orientation should be respected. No matter which one it is, there is no need to feel sorry or ashamed for it."

Zheng Mingchi stood up from the chair, and said to Rong Yu: "This is what I mainly want to tell you in this class, do you understand?"

Rong Yu frowned and thought for a long time, then nodded slightly.

“Fish is awesome.”

Zheng Mingchi praised Rong Yu as usual, then turned and went to the bathroom.

Then came the sound of the shower.

There is also the sound of water mixed in, it seems that there is no attempt to cover up, low breathing.

Rong Yu felt that his face might have developed the ability to change colors today, red and white, hot and cold... He took out his phone and looked at his watch, and found that there was still some time before the lights were turned off, so he struggled for a while. I still took out the textbook from my schoolbag and prepared to review today's homework.

Although I don't know if I can read it under this kind of background sound - there was a message from Miao Jiajia in WeChat asking about homework, Rong Yu sent it to her according to his answer, and then lay down on the table After thinking about it, I still sent a question to Miao Jiajia.

#鱼#: Jiajia, are you asleep?

Jiajia is the cutest: No, I just finished my homework ah ah ah I'm going to play on the computer for a while!

#鱼#: That... I want to ask, do you have x education courses in elementary and junior high schools?

Jiajia is the cutest: Huh?Do you mean x physiology education class?

Jiajia is the cutest: Yes!Don't you?

Jiajia is the cutest: Oh yes... Maybe you don't have any... Rongyu sent Miao Jiajia an emoji and ended the conversation by the way.

Then he sat on the chair and thought seriously, from this point of view, it seems that there is nothing unusual about Zheng Mingchi giving himself science popularization—the sound of water in the bathroom stopped, Zheng Mingchi pushed the door and walked out, quickly wiped the water and changed casual clothes.

Rong Yu was a little surprised and asked him, "Are you still going out? Why don't you just change into your pajamas?"

Zheng Mingchi threw the mobile phone into his pocket casually, and smiled at Rong Yu: "I suddenly remembered something, I have to go home, I probably won't be going back to the dormitory tonight."

Rong Yu was stunned: "Oh..."

"Unhappy?" Zheng Mingchi took out a lollipop from his pocket and stuffed it to Rong Yu, "Save it for you to miss me, I'll be back tomorrow."

Rong Yu: "..." Who wants your lollipop!

Zheng Mingchi said: "Okay, go to bed early and cover yourself with the quilt. Good night."

The bedroom door was closed again, and Rong Yu was stunned for a while, then slumped back on the seat.

I always feel a little uncomfortable... like throwing it away after being used...

Rong Yu thought for a while and decided to go to bed.

Before going to bed, he specially turned off the night light beside the bed, thinking angrily that Zheng Mingchi would come back tonight!Don't leave him a light either!

And Zheng Mingchi probably won't need the night light tonight, he received a call from Tao Hua just as he left the house.

Tao Hua seemed quite leisurely: "How is it? Is the USB flash drive I found for Rong Yu useful?"

Zheng Mingchi got into the taxi, and said with some headache: "Why did you get him such a big scale."

Tao Hua laughed: "I don't have small-scale ones here, I have sifted through them all."

Zheng Mingchi: "..."

Tao Hua took the conversation back and changed his tone: "I didn't call you to talk about this. I heard from my mother today that your parents are coming from J City, you know?"

Zheng Mingchi looked at the dark night outside the window: "I know, I'm already rushing home."

Tao Hua paused: "Okay, you just need to make some preparations yourself, remember to speak up if you have something to do."

The author has something to say: Rong Xiaoyu: This kind of play is really shameful. .I want to say no. . .

Ochi: But I like _(:3」∠)_

Rong Xiaoyu: ...

Tao Huahua: Tsk, what is this kind of play, young people~~~——
