Track1　Voices that are made to be used by my sister in the bathroom

(Recording time: 18 minutes 28 seconds) Hehe, this is an “erection”, right?
This is a phenomenon that occurs when a boy becomes sexually aroused, and his penis becomes larger.

Oh my, were you excited to take a bath with your sister and get washed?
Hmm, that’s why you were hiding your crotch just now so your erection wouldn’t be seen.

Hehe, your brother is also a boy around that age.
Did you get excited by having my breasts wash your back?

The feeling of her still immature and underdeveloped breasts on my back made my cock go wild.

Ufufu, I can’t help it.
When a boy gets excited, he naturally gets an erection, right?

When I went to wake up my brother in the morning, there was a bulge in the front of his pants.

At first I thought it was strange that he was hiding something in his pants, but…
One day, my brother didn’t seem to wake up at all, so I looked inside his pants!

Hehe, I was surprised because the cute penis I saw a long time ago had turned into a magnificent matsutake mushroom.
After that, I got curious and looked it up on the internet, and found out that it’s called morning erection, and that boys naturally feel more energetic in the morning.

Also, regardless of my intentions, when I do something naughty, my dick gets bigger.
Hehehe, it’s cute how he grows so forcefully, regardless of what he thinks. While young boys and girls with immature sexual knowledge are living their normal daily lives, a girl accidentally kicks a boy’s balls.
“I only kicked her lightly…” The boy writhes in agony, ignoring the suspicious girl.
This is a collection of voices of boys and girls who are curious about the physical differences between men and women and learn about sex.
