Mihono Sanjo, 32 years old, mother of one. Miho is a natural service-oriented Mihono who always ends up devoting herself to her man. However, perhaps due to this personality, her husband, who used to lead her in a manly way, has become completely selfish and their nighttime activities have become completely king-like. Gradually, she began to feel that "I'm not your servant," and her desire to commit adultery, something she had never experienced before, grew stronger. "I'm embarrassed to say this, but... I'm a masochist, so I want to be fucked hard..." Her pent-up sexual desire and suppressed abnormal desires open the door to immorality for this beautiful, pure wife.
