After five years in a loveless arranged marriage, Kanna develops an exhibitionist fetish. Working as a nurse in an adult school role-play, she becomes aroused by the masculine scent around her and waits for the opening bell to empty the halls. There she exposes her most shameless side, addicted to the thrill of being seen. Her displays grow bolder until adult student-role performers catch her, after which she begins satisfying herself through sex with the aroused men.
