In a dystopian adult school role-play, the government admits that its “chaste society” has failed, establishes a sex-education committee, and passes a mandatory creampie-duty law. Aizawa Miyu is selected as the new model case and made an officially sanctioned sexual outlet tasked with spreading the pleasure of creampie sex. She takes the desires of adult student and teacher role-play partners morning, noon, and after class, enduring nonstop group sex and repeated creampies in a relentless campaign of impregnation fantasy.
