Story
Her younger sister Mana is a shy and kind honor student.
But she shows the exact opposite expression only to me.

Asana was a bright, well-dressed girl from an early age.
I had been feeling inferior to her as her girlish loveliness gradually blossomed, but

That was my little sister, and I was determined not to mess with her.

It really is a distraction.
I found Mana’s pants in the laundry basket by accident.
It was unbecoming of an older brother, but I was so lustful that I brought it back to my room and used it as a side dish. ……

From that day on, Mana’s attitude changes drastically.

She became overbearing only towards me, coming to my room every night, provoking me and demanding sexual relations.

That well-mannered Mana is …….

I know in my head that I can’t go on like this, but when Mana’s seductive voice accuses me, I can’t refuse.

[I’ve locked the door. You can’t come in now, mom.]
You can’t resist the temptation of Mana again today.

Heroine Introduction
Mana Fujishiro (CV: Yuri Matsuoka)
She is a student at a famous private school. Her special skill is playing the violin.
A beautiful girl with excellent grades, seriousness and honesty, a good listener, and a good reputation in the neighborhood who has nothing to complain about.
Ever since she discovered her brother masturbating in his own underwear.
It’s not that I don’t like my brother, I just don’t like him.
It’s not that I don’t like him, it’s just that I think that by keeping his secret, I’ll be able to keep him to myself.
The truth is, I love my brother.
I’ve been worried about my infantile body size, but now that I know my brother’s sexuality, I’m more confident.
I am proud of the fact that my brother sees me as a sexual object.
Recently, I’ve been improving my sexual knowledge through my brother’s erotic magazines and comics, and I’ve started to learn some of his favorite sex words.
I really love my brother.
