This live-action adaptation combines both hit works from Momojiru Teien. Adult literature-club junior Izumi secretly reads the erotic novel written by his quiet, refined senior and is stunned by its obscene content. Circumstances lead them to have sex, and from then on they reenact the fantasies in her stories day after day. The novels reveal her real masochistic desires: forced deep-throat, creampie sex and being used like a masturbation toy. Freed from her modest exterior, she abandons herself to instinct and spends her days fucking him.
