[Synopsis]
My mother is in a bad mood every day.
Because of that, my father avoids her, saying that his business trip has been postponed and he can't come home.
The way to turn my mother back into the kind mother she was before was to make her anger peak and make her violent.
By becoming violent, my mother's anger is reset and she can return to her normal kind self.

Harutaro, the son, is determined to make his mother angry and succeeds in making her hit him.
However, this time, his anger is different from before.
His mother, who was doing karate, punches and kicks with all her might and Harutaro faints with more power than he expected.
His mother regains her senses and cries and apologizes.
Harutaro regains consciousness.

Harutaro asks his mother: [Your irritation this time was terrible, unlike before. Did something happen?]
His mother confesses: [Actually, I have not had sex for months. I really like sex. I think I'm addicted.]
And his mother's eyes began to desire Harutaro as a man.
From there, the forbidden mother-son incest begins... ( ͡° ͜ʖ ͡°)
