The movie consists of four separate parts acted by four actresses, but only two main storylines.
The first part is also the first storyline about the illicit affair of Wakatsuki with a young pilot who went to the toilet. Disappointed with her old husband, each time their relationship fails to satisfy her desires, she always seeks a young, healthy man to please her. Coincidentally, the neighbor boy fits the type of man she desires. After going to the toilet, she stood at the door and seduced him, the young man, eager to experience something intense, boldly responded. Later, when her husband returned, they panicked and hid in the bathroom but didn't stop there, continuing their affair while the husband remained unaware of what had happened.
The other three parts share the same storyline. The actresses, upon discovering they were being watched by mischievous college students, forced them into their homes to deal with the situation. The students were scared, thinking they would be punished, but no, because the women were too promiscuous and desirous of sex, they found ways to invite the students in for intimate relations.
