【your sister】Class is closed, so health and physical education class, big brother, please!

I’m sure you’ll be happy to know that I’m not the only one who has a problem with this.

I’m sure you’ll be able to find something that works for you.

[Puberty is a period of transition to adulthood] Okay, so I’m going through puberty? Right?

During puberty, the secretion of sex hormones increases and reproductive organs develop. What are sex hormones? Big brother.

I don’t know. I’m sure you’ve heard of it. Is that what it is?

I’m sorry. I’m sure you’ll be able to find something to help you out.

The seminal vesicle and prostate are inside the body, so skip them.

The [penis] is in the body, so skip it.

The next one is [testes].

My brother, it happens to be hard to see you in your current position, so I’ll just move my face a little closer. Sorry, thank you for listening to my selfishness.

What? Why are you hiding your penis all of a sudden? I’m sorry, I held it in so long that I peed my pants. I’m sorry, big brother. I’m sorry, that was embarrassing. Are you okay?

I’m sorry, big brother. I know it’s embarrassing, but can you take out your penis again? Don’t worry, I’ll take care of it. I’ll wipe it off for you.

Hey, big brother? What’s wrong? Big brother, you know, we’re brother and sister, so don’t be shy, remember? You wiped my crotch when I peed my pants, right? What? Yeah, that was back in preschool, but age doesn’t matter.

You know what? Big brother, don’t hide your penis. You’re a good boy. Can you move your hand to cover your penis? Yeah, take your time. Yeah, yeah, you’re good.
