BASJ-019 A depraved, lustful woman who warps a boy's sexual preferences and sends his life into hard mode: Reiko Koyakawa

A boy entering puberty with an insatiable interest in sex. He just wants to do perverted things and falls into the trap of a married woman. The woman enjoys twisting younger boys to her liking and meticulously raises them to be M, getting excited as they beg to ejaculate. The boy, unaware that his life has become hard mode, goes to the married woman just to ejaculate. Eventually, he is teased until he can't ejaculate on his own, becoming an ultimate perfect M slave. Once he becomes this, he will repeatedly endure endless ejaculations until the woman gets bored.
