Momone, a college professor, suffers disturbing dreams about sexual deviance from her youth. She dismisses the memory and heads to class. Along the way, every boy stares at her with lustful thoughts about the voluptuous teacher. The basketball team captain is fond of her, but his rival Hino has other intentions. When Momone confiscates a pornographic magazine from some boys, Hino claims it is his and asks if it arouses her. Back in her apartment, Momone examines the magazine, which does indeed turn her on. Hino makes a dramatic entrance and dominates his professor, forcing Momone to become his submissive. The next day, following Hino's instructions, Momone wears no underwear. This is part of Hino's plan to fully claim Momone as his own. And he is certainly not gentle about it.
