Nanami, an honor student at school, was on the verge of breaking down from the stress of interpersonal relationships and entrance exam studies. One day, she impulsively shoplifted from a convenience store. She was caught by the store manager, who told her, "If the school finds out, you'll be expelled. I'm short-staffed, so if you come to work starting tomorrow, I might let it slide." From then on, Nanami became the plaything of the malicious manager... She continued to be raped inside the convenience store as a sexual relief part-time worker... Forced to work as punishment for shoplifting, the girl is called in 24 hours a day to be a submissive meat toilet inside the store.
