A housewife, Tamaki, lives with her college student son while her husband is on a long business trip. Her recent concern is that her son's room has become a gathering spot for his friends as he prepares for job hunting. One day, as she tries to take a bath as usual, she encounters one of her son's friends masturbating in the bathtub, and they see each other naked. From that day on, her ordinary life disappears. She becomes a sexual outlet for her son's friends and gradually loses her sanity. A housewife torn between pleasure and guilt as young men toy with her body!
