A married woman living with her husband's parents begins to notice his extreme mother complex, leaving her emotionally hurt. He used to be assertive and passionate, making her feel his masculine charm, but now she admits, "I can't see him as a man anymore," and they haven't had sex in over a year. Driven by pent-up sexual desire, she travels to Tokyo and indulges in intense threesomes with men other than her husband. Eagerly drinking the men's cum, she fully reveals her wildly lustful side.
