Nanami is a straight-A student, and the pressure from exams and everyone around her has her close to breaking. One day she snaps and shoplifts from a convenience store — and the manager catches her. “If your school finds out, that's expulsion, isn't it.” “We're short-staffed. Start a shift tomorrow and maybe I didn't see anything.” From then on she's his. Kept on as the store's sex-relief hire, used again and again behind the counter. An adult student forced into work as punishment for stealing, on call around the clock, an obedient cum-dump inside the shop.
