Kyouka looked rather displeased as she and Misa stood in front of Ren's door, discussing whether this was really the right time to go through with this. But Misa had to remind Kyouka that tomorrow was the deadline for Ren's semen sample—otherwise, a medical team would come to forcibly take him to the hospital.

"I know... but with everything that happened..." Kyouka muttered. Misa clutched her head, clearly confused and conflicted herself.

"What am I supposed to do, Kyouka? Should I let them take him and strap him to a machine, traumatizing him even more? He's definitely scared of women and any sexual activity, so I need to make sure he's comfortable with everything... after all, he's precious to us, and I don't want to see him looking sad." Misa placed her hand on the doorknob, but Kyouka suddenly put her hand on her mother's shoulder.

"Mother... you're shaking," Kyouka said, noticing Misa's trembling hand. She sighed. "Mother... you have a deeper bond with him than any of us. I'm his sister, even if not by blood... so I'll do this. You're his adoptive mother, so I think it's better if I'm the one."

"But—" Misa began, but Kyouka cut her off. "I'm closer to his age... so I'm the most suitable person for this. Just let me."

Misa thought long and hard, then looked at Kyouka. "Do you have any experience?"

Kyouka glanced down, her cheeks flushed. "I've seen a few videos. I can manage... give me the vial, I'll fill it." Muttering those words, she took the vial from her mother's hand.

Misa gave Kyouka one final look as Kyouka entered the room. With a sigh, Misa stepped away so she wouldn't be tempted to peek or listen to what was going on inside. Still, she was determined to give the harshest punishment possible to the girl who had tried to assault her son—and had already planned a meeting with the girl's mother.

"I'm not letting this go until I get justice for my son."

Meanwhile, Kyouka's heart pounded like a drum as she stepped into Ren's room, the door clicking shut behind her with a soft finality. The room was dimly lit, the curtains drawn against the windows making room darker than it should be, casting long shadows across the bed where Ren sat huddled under his blankets with the light of his lamp.

He looked up startled, his eyes wide and wary, like a cornered animal. Ever since that horrific incident at school—the girl who had tried to force herself on him—Ren had withdrawn into himself, barely speaking, avoiding eye contact with anyone, especially women.

At least, that's what Kyouka and the other girls think is going on. In reality, Ren is avoiding contact with Misa, Kyouka, and Hiyori because he's afraid his ability, [Yandere Believer], might affect them. After all, they're the first people he doesn't want to end up pushing knives into his back.

"Ren... it's me," Kyouka said softly, trying to keep her voice steady. She clutched the small vial in her hand, her palm sweaty. Her cheeks burned with embarrassment, but she pushed it down. This was for him. For her brother.

Ren pulled the blanket higher, up to his chin. "K-Kyouka? What... what are you doing here? Mother said she wanted to discuss something with me.."

She took a hesitant step forward, forcing a gentle smile. "I know, but... we need to talk. It's important. About tomorrow. Did you hear what's happening tommorow?"

Ren looked confused, but Kyouka decided to come clean without beating around the bush.

"Ren, you know about the sperm bank, and how every male is required to donate semen to the process as soon as they turn eighteen."

He immediately understood where this was going, but what he didn't expect was that Kyouka had come to jerk him off instead of asking him to do it himself—since, in this world, the concept of males masturbating was uncommon. After all, it was usually the girls who masturbated.

"What do you want me to do, Kyouka?" Ren asked.

"I'll take the semen from you, so until then, you have to try your best to stay calm, Ren. It won't hurt, I swear. I'll be as gentle as possible," Kyouka muttered, though she wasn't exactly the most convincing. That might have been enough to unsettle the previous Ren, but the current Ren was grinning inside, knowing he was about to get a handjob from a beautiful girl.

"HELL YEAH!" he shouted inwardly. He might have hated overly crazy bitches, but that didn't mean he disliked sex—in fact, he actually enjoyed it. Even with a crazy girl like Yuno, he'd had plenty of sex… at least until she started showing her more unhinged side.

Kyouka moved closer to Ren, while he sat on the bed, careful not to let his overly excited expression show. He knew it was time to get some training and see how different his body was in this world compared to the last one—because, according to Luxy, there had been some genetic changes in both males and females.

"Would you like something to drink, Ren?"

He really just wanted to proceed with their semen collecting process. Just the idea of this silver haired beauty, trying her best to collect his semen was enough for Ren to feel more and more excited.

"I am fine, thank you. If that is alright with you, can we start this right away?"

Seeing the expression on her face, Ren knew she was surprised by how well Ren took this. She sat in front of him.

"Of course. So, um, how should we start? What are you curious about?"

"I would like to know more about sex, Kyouka. I don't know much about it, so it would help me if you tell me what exactly is going to happen."

His supposedly innocent bluntness surprised her, in a very good way. Her grin was only growing larger and lewder by the minute unlike what she excepted to happen because she thought she will quickly collect semen and rush out of the room knowing how dangerous it will be for her to be in front of this handsome man. She nodded several times quickly and answered.

"Yes, that is very important. Let's see... As I know insertion is when the woman puts the man's penis inside of her vagina and sex is the act of the woman stimulating the man's penis until he reaches ejaculation. It is the way a woman can get impregnated by a man's sperm, which will allow her to have children. But, most of the time, sex is just used by the two partners to have fun, since it is an extremely stimulating and pleasant process. Pretty much all the women in the age of procreating use the pill, which is a very safe way to avoid pregnancy. O-of course I haven't had sex yet."

She let out her not very subtle desire a bit at the end and was somewhat red in the face by the end of her explanation. Even though Ren didn't learn anything new, he still noted that her choice of words was a bit weird, very centered around everything being done by the women. He was curious about that so he directly asked her.

"This is very interesting. But, from the way you phrased this, it seems that the woman is doing everything during sex. What is the man doing then?"

She let a small resigned laugh at that question.

"Most men... don't want to do anything during sex. This is because the act of sex is traditionally about impregnating a woman. That implies making the man ejaculate inside the woman, and it is the job of the woman to make that happen. Of course, that isn't all bad for the woman, since that doesn't mean they can't get a lot of pleasure from sex, as they also get greatly stimulated during intercourse."

Now that was new information for him. He could hardly hide his happiness when he heard that. Interpreting what she said, didn't that mean that active men during sex were rare? This meant that if he was active, he would surprise the women and let them experience something completely new.

If he thought that he was hot stuff before, he was now more and more convinced that it went even beyond that, like a winning lottery ticket or something. He then asked her another question.

"I see... And so, concretely, how does sex work? I, um, I know you agreed to teach me but I don't want to abuse your kindness. I-if possible, could you give me a practical experience, I mean that's how you're going to collect these semen sample right?"

"Yes! Oh... I mean, of course, we can, we are here so you can learn it all, after all. You should not hesitate to ask me anything, right, absolutely anything!"

The idea of just quickly giving a handjob to Ren and collecting his semen suddenly vanished from Kyouka head, as she realized Ren was asking her to teach him sex.

Her excitement was already reaching a very high level and she could barely contain herself. He wasn't in a much better state, his hard-on already visible through his pants.

"First, you can take off your clothes and lie on the bed."

He did as she said and started taking his clothes off. As soon as he removed his top, her eyes focused on it, her face full of desire. When he removed his pants and underwear, her line of sight immediately moved down, admiring his erect member for a long time. She finally took her eyes away from the scenery and removed her clothes.

"Aren't you going to remove clothes, Kyouka? You told me...both partners have to be naked," Ren asked in an innocent tone.

It wasn't a big deal for Kyouka to take off her clothes—after all, it was normal for women to even work topless—but for some reason, she started to feel shy and embarrassed. Despite that, she slowly took off her shirt, then her pants, moving on to her ladylike panties and bra.

It was now his turn to focus on her body and he that noticed her pussy was neatly trimmed. It was literally drenched, drops of juice falling to the ground. Now that they were both nude, he went to lie down on the bed. She restarted her explanations, approaching him.

"It is very important for the man's penis to be erected and lubricated beforehand, to avoid hurting it during the insertion. This is called foreplay."

That was yet again the reverse of what he knew. He asked her.

"What about the woman, isn't she hurting during the insertion?"

"Not at all, women's vaginas can lubricate themselves, making any foreplay unnecessary. Contrarily to the men's erections, women get wet extremely easily and do not need any external stimulation."

She climbed on the bed, her head now at the level of his cock, and concluded.

"Shall we start now?"
