Imakara Atashi......

Lunch break at the school.

There is a place where the siblings Ryosuke and Yayoi can be alone and undisturbed.

Why do they meet in secret?

That is because they are more than brother and sister.

Sex is on their lunch menu.

However, only anal, because they are siblings, and Ryosuke is vary to cross the last line.

Yayoi is full of happiness because she loves her elder brother, a love she feels will last for all time...
