CHAPTER 682: SEX-ED IN SESSION (R-18)

"What do you need me to do?"

Xiaoyun asked, trying his hardest to hold in his giggle as it was abundantly clear what was going to happen.

"Do you mind taking off your pants in front of the class for everyone to see?"

As the two of them both looked down at the class, none of them shied away from it, other than Lily, who tried to cover her face with the textbook.

"I’m more than happy to be used as the prop. But I don’t think the transfer student is comfortable with it."

"Lily, are you uncomfortable with it?"

"N-No, Miss Chen."

Lily instantly replied, putting the textbook back down onto the desk as if she was scared of Leyan making her step out of the room.

"Great, then I’m going to start the class again... Xiaoyun, can you sit down at the desk and take off your pants?"

Xiaoyun quickly followed Leyan’s direction, sitting down before pulling his pants all the way down to the floor.

"Your underwear too."

All of them could see with their own eyes the massive boner popping right out of its last remaining restraint.

"Okay, now I need you just to remain still. You don’t have to do anything else... I’m just going to explain each part of the organ."

Seeing Leyan pick up her ruler right next to him on the desk, Xiaoyun suddenly felt a chill go down his spine.

"Miss, y-you are kind of scaring me." Xiaoyun nervously murmured.

"What are you scared of? Come on, I’m not going to hit with you this or anything... Unless you want me to."

"You’re very funny, Miss... Chen."

"Ahem, back on topic. So the organ near Xiaoyun’s crotch is called a penis. It is the sexual organ that a man has."

As the ruler made a swoosh sound, the cold breeze didn’t make him move a single bit, as his leg was completely still.

"The current state it’s in is called an erection... Do you mind having it softened so I can showcase it to the class?"

Xiaoyun sat still, looking back at her in silence as if he was expecting something back from her.

"Hm?"

A single, gentle tap with the ruler instantly made his penis soften within a matter of seconds, his mind realizing Leyan was playing him.

"This is what a flaccid penis looks like... Usually, it either starts small and grows big, or it’s already big and grows a little.

The two terms used to describe them today would be shower and grower. But since Xiaoyun is a little special, he starts big and grows even bigger..."

Leyan didn’t elaborate any further, her voice getting quieter and quieter as if she got a little embrassed saying it out.

"Okay, you can get hard again.’

As the penis becomes fully erect again within the blink of an eye, Leyan finally drops the ruler onto the side before moving closer and closer to it.

"You all can move up to the front to have a better look for yourself... The next part is going to be a little hard to see for those in the back."

All of them immediately carried their chair with them to the front. Even Lily moved her chair to the front as she sat next to Nami and Yuqi.

"Now this part is going to be on the test, so I want you all to listen carefully... This part is the foreskin, and this part is the glans..."

Seeing Leyan starting to explain his penis as if it were an actual prop with a fully serious face, Xiaoyun’s heart felt a little guilty.

She was genuinely teaching every single technical term to them, ones that are clearly only used in a biology class.

But the guilt soon vanished as Leyan’s hand gently pulled his foreskin all the way back to expose his glans.

"Hm."

A little groan came out of his mouth as he hadn’t done it for the past week since he went inside Tianci’s lab.

"Oh my... This clear, colorless liquid that’s coming out of the tip right now is called pre-seminal fluid, or precum.

It is a lubricant that comes out of the penis to prepare for sex, meant for a smoother transit for the actual sperm in male ejaculation to travel inside the vagina."

Leyan’s shift quickly changed back to serious mode as she didn’t expect his body to be so sensitive from just peeling his foreskin.

"Although it is called pre-cum, it often does not contain sperm itself... Notice how I use the word often?

It’s not a zero percent chance. There’s always a chance for it to slip by, so always wear protection even if the person is telling you he can do it raw and ejaculate outside."

As she continued explaining her lecture, both Kate’s and Anna’s faces started blushing a little as if they were being singled out.

"Miss Chen, I think that’s a little off-topic," Kate murmured with a hint of irritation in her voice.

"Of course not... Now, since we got a real penis as a prop, I’m going to show you guys what male ejaculation looks like."

Xiaoyun’s heart immediately skipped a beat, but he was soon disappointed as she only looked back at him in silence.

"What?"

Despite asking her in confusion, seeing Leyan pick up the ruler immediately made Xiaoyun realize what she wanted.

"There you go... You aren’t that dumb after all."

As he gently stroked his penis with his own hand, Xiaoyun had no choice but to stomach her arrogant tone.

"Make sure you ejaculate onto your hands. I don’t want my desk to get all dirty... What are you looking at?"

"N-Nothing."

Xiaoyun quickly turned back around, facing towards the student rather than looking at her suit that could barely hide her cleavage.

"Does anyone remember what the makeup of male ejaculation is?" Leyan suddenly asked as she sat down next to him.

Seeing Shuli being the only one who raised her hand, Leyan picked her.

"Is it 5-10% sperm cells and 90-95% seminal plasma?"

"That’s the correct answer... Now, does anyone know what’s inside the sperm that could make a baby when mixing with an egg?"

This time, both Lily and Wuli raised their hands. Leyan picked Lily in the end as Shuli pulled Wuli’s hand back down.

"Is it DNA?"

"Bingo. Now, does anyone know what the chemical composition of a male ejaculation is?"

Not a single person raised their hand. Not even Shuli, as she looked back at Leyan with a confused face.

"I’m just joking. That won’t be on the test... But if you wanted to know, it is mostly made out of water, like 90% of it."

As Leyan stated the most random fact in the lecture, Tianci suddenly got up from her seat as she let out an ah sound.

"Tianci, you okay?"

"S-Sorry, I just remembered something."

With her seat back down, Leyan didn’t think too much about it as she continued with her lessons.

"Further down the penis’s shaft is where the male’s testicle is located... This is the organ that produces millions of sperm per second and controls testosterone production."

As Leyan pointed at Xiaoyun’s testicle with her finger, she showed zero interest in helping as she watched him continue stroking his own cock.

"Underneath all these skins are tubes, where, if it is dissected, it will show a connection to the rest of your body."

"Can we not talk about dissecting?" Xiaoyun quietly murmured as he felt a little scared when hearing her say it out loud.

"What? You scared of me turning your penis into an actual prop?" Leyan jokingly asked, her finger making a sissor motion.

Xiaoyun didn’t say anything back, but his hand was starting to move faster as if he just wanted to get it over with.

"All of the things I talked about are only the front. Technically, there’s also the back with the whole prostate that’s heavily connected to the reproductive system.

Since today I forgot to bring the prop, I’m not going to talk about it... But it will be on the test, so remember to read the textbook after class."

Xiaoyun let out a small sigh of relief as he got a little scared after the second sentence.

His mind seriously thought Leyan was about to use him as an actual prop, about to tell him to turn around to show his ass in front of everyone.

"What’s taking you so long? Can you not just show what male ejaculation looks like to the class?" Leyan asked as she started to look a little impatient.

"Sorry. I can’t really do it by hand."

Xiaoyun apologized, his face smirking a little as it was finally his turn to flip the script onto Leyan.

"If you can’t do it by hand, how often have you had to masturbate? Did you masturbate so much that you lost your sensitivity?"

Leyan’s question didn’t make any sense as it was far from the opposite, but he kept playing along with it as he awkwardly scratched his head with the other hand.

"I... I have no one else to have sex with other than with my hand."

Xiaoyun’s eyes looked all depressed as his penis started to soften. His hand had come to a complete stop as she let out a small sigh.
