In Japan's future, where there is an extreme decline in child population due to super low birth rates and aging society, the Sexual Education Committee is established. As a result, they pass the 'Sperms-on-Duty Law', which encourages students who have little interest in sex to participate in coital activities that promote procreation! A female student is chosen as a model case for this program, becoming an officially sanctioned orifice through which sperm can flow freely. She endures nonstop pregnancy-inducing sex throughout the day, satisfying both her fellow students and male teachers' desires. This school is dedicated to uninterrupted creampie sex, leaving no room for anything else!
