In a dystopian adult school role-play, a sex-education committee responds to a population crisis by enacting the Next-Generation Population Development Act, better known as the “Creampie Law.” Chinamii Natsuno is selected as the model case and ordered to serve as a government-approved sexual outlet, teaching other adult students the pleasure of creampie sex through repeated breeding sessions. As she obeys the teacher and lets her body be used, she gradually becomes aroused. The male adult students become addicted to the pleasure and keep filling her with cum morning, noon, and after class.
