Former fighting champion and now a full-time housewife, Hibiki Otoshi. She challenges a local brat, Yuuto, to a fight in the middle of the night, saying 'Obey me if you lose!' After losing the match, Yuuto, filled with regret, secretly drugs Hibiki with an aphrodisiac and challenges her again. Hibiki loses to Yuto because he can't perform due to the aphrodisiac. Hibiki challenges Yuto again but is told, 'Once you cum, you'll do whatever I say,' and ends up being made to cum repeatedly by the aphrodisiac, becoming obedient afterwards.
