DASS-992 · Perfect Defeat Big Sister: The Undefeated MMA Champion Who Lost to a Weak Brat - Hibiki Otsuki

Hibiki Otsuki is a former martial arts champion and now a full-time housewife. She challenges Yuto, a neighborhood brat who wanders around at night, to a fight, telling him, "If I win, you have to do whatever I say!" Frustrated by his loss, Yuto secretly spikes Hibiki's drink with an aphrodisiac and challenges her to a rematch. Unable to use her strength due to the drug, Hibiki loses to Yuto. She tries to challenge him again, but he tells her, "If you cum, you'll be at my mercy." Driven to climax repeatedly by the aphrodisiac, she eventually becomes his obedient sex slave.
