Mina wa Onii-chan ni Shojo o Ubaware Ie kara Derarenai.

━━A peaceful everyday life, a peaceful life, or so it was supposed to be.

The innocent girl Mina was in a pure relationship with her boyfriend and everything was going smoothly.

But then, after a small incident her life began to fall apart.

Mina's brother, Kenichi, trusted her, but he began to grow suspicious of the adolescent girl's behavior, and he decided to rape her.

"If you don't want to get hurt, do as I say, Mina."

Faced with unreasonable demands, Mina was unable to leave the house, and her confinement and training, in which her body was licked all over, began.
