A female teacher unfortunately shoplifts an SM novel she found in a secondhand bookstore. She reluctantly takes it home, but her interest grows and she becomes absorbed in reading it. Drawn into a world where teachers are tormented by their students, the woman indulges in masturbation. The next day, when she is called by the store owner to go to the store, she is shocked to see security camera footage of the shoplifting. She is forced to sign a slave contract without question, is declared a pervert for shoplifting an enema novel, and is threatened with telling the principal, blocking her way out. She is then sacrificed to an SM club for anal torture.
