Iori Nanase has her pubic hair shaved for the first time, leaving her completely bare, before malicious adult student-role performers subject the teacher to relentless sexual humiliation. She is tied up naked in the infirmary and forced to drink water, while a perverted participant gulps down the urine she can no longer hold. Iori then cries as she is made to show a grotesque pantyhose-stretched face before a crowd. The climax surrounds her with the adult student-role group for public sex, ending in a mass facial cumshot.
