Hibiki Otsuki is a former martial arts champion who is now a housewife. She challenges Yuto, a mischievous neighborhood *** who is out at night, to a fight, telling him that if he can beat her, he'll have to obey her. After losing the fight, Yuto, frustrated, secretly slips an aphrodisiac into Hibiki's drink and challenges her to a rematch. Hibiki is unable to use her strength due to the aphrodisiac and loses to Yuto. Hibiki challenges Yuto to a fight again, but he tells her, "If you cum, you'll do whatever I say," and continues to make her orgasm with the aphrodisiac, after which she becomes his obedient slave.
