Newly hired teacher Suzu, blessed with a big, sexy ass, decides to hold after-school lessons at her home in an attempt to reform Shota, the class delinquent. But her voluptuous backside quickly becomes Shota's prime target for mischief. In the bathroom, he spies on her bubble-covered ass as she bathes, and at night, he sneaks into her room to perform lewd acts on her sleeping, shapely rear. Soon, her ass is licked, then taken from behind, and in just one night, Suzu’s resistance crumbles completely. Her ass grows increasingly aroused, driving her to obsessively seek out Shota’s cock even at school. In the restroom, she climaxes from cunnilingus and grinds her ass against him; in the classroom, she thrusts her hips back, flashing her anus as they engage in explosive creampie-filled threesomes. A lustful, ass-obsessed female teacher is born, utterly addicted to cock.
