Japan was engulfed in a demographic crisis, forcing the government to implement the "Ikumonogakari" law, which permitted promiscuous sexual interactions among the people. They started doing practical and pedagogical activities on the lessons of sexual life and a partner's sexual fulfillment. The protagonists are young and inexperienced, so practical exercises will help them to improve their skills.

A married couple runs a coffee shop, but the husband is currently in the hospital. The wife pleads with the landlord to wait for this month’s rent. Pretending to be a good guy, the landlord uses that to blackmail her. He gropes her ass while she’s working and whispers in her ear “You want to protect this place, don’t you?” when she tries to resist him. She then becomes his outlet to release his sexual frustration.

Etou, a fat and unattractive student, has feelings for Sayako, his popular and friendly classmate. While wandering at night, he sees Sayako being harassed by some men. Initially reluctant to get involved, he ends up helping his classmate. However, when they are safe, Etou realizes that Sayako is very different from the one at school. The truth is, she has a dual personality; during the day, she’s a modest and kind student, but during the night she is a vulgar girl with a lot of sexual desire. Now that they are both alone, Sayako shows her lust and fucks Etou.
