A janitor who indulges in masturbation with an SM magazine in one hand in a dull room. In the back of a man's mind, there is a bondage figure of a female teacher who had a crush on him... One day, when a woman asks him to repair her apartment, a man finds an adult toy hidden in a small box in a drawer while the woman is away. The man who caught a glimpse of the woman's weakness loses his reason and tries to tie her up and tie her up... An old man's obscene sex play, a woman who is relentlessly accused of her wet vagina and writhing in shame, is disciplined by her masochistic habits, and becomes a captive of a perverted old man!
