Chinami is a frustrated housewife who indulges in masturbation every day, unknown to her husband. At one point, she can’t take it anymore and begins to lose her mind. One day she goes to a public male restroom and locks herself in a stall. She heard the guys come and go for a while, and at some point, she undressed and deliberately leaves the door open.
