A beautiful masochist teacher invites a natural masochist idol student who has seen through his masochistic temperament into the abyss of masochism! ! ! ``I can't stop studying because I can't stop having sexual fantasies.'' The teacher Shiokawa, who was worried about the situation, called out to him. Shiokawa desperately complains that she is controlled by the delusion of being raped by a man, but he tries to lure her in by telling her that he has a secret club. It's a behind-the-scenes activity at school, where sadistic and masochistic people gather together.
