In response to unprecedented low birth rates, the sex education committee implemented a policy known as the "Next Generation Population Development Basic Law" (commonly referred to as the ND Law), or what is called the "inside-out law." The role given to "Natsuno Chiyomi" selected as the model case is to make other students experience the pleasure of in-semen sex, becoming a government-approved outlet for sexual release, and receiving impregnation sex! As she follows the teacher's instructions and uses her body passively, she unknowingly becomes aroused...! A boy possessed by sexual pleasure keeps ejaculating inside indiscriminately, whether it's morning, noon, or after school!
