MVSD-578 Mei Itsukaichi, a tutor, is drugged and taken by her student's father Ippei in a sweaty daytime affair with creampies and squirting

Haruto's father Ippei spends the late mother's insurance money on drinking and gambling, so Haruto studies alone to get into a national university. His homeroom teacher recommends a private tutor, and Haruto is drawn to Mei, a beautiful and kind young woman. Ippei, annoyed by their closeness, waits until Haruto is out and gives Mei a powerful aphrodisiac. She screams and convulses from the relentless pleasure, her back arching and fluids spilling as Ippei takes her in a hot, humid room, and the cycle continues day after day.
