To fight against the declining birthrate, the local government set a new law called “Ikumonogakari”. a group of students arrives to participate in a sex education class. As time passes, they put their newly acquired knowledge to use through hands-on experiences and practical exercises. Living together in a small place, the boundaries between lessons and personal desires are starting to blur. The students find themselves unable to resist the temptation of engaging in wild orgies that break out in the bathrooms and bathhouses. The allure of uninhibited pleasure proves to be irresistible. In the heat of the moment, the students abandon the use of condoms, succumbing to the thrill of unprotected sex and the allure of internal ejaculation.
