At the masked instructors' special classroom, intense discipline takes place once again today. Under the guise of a lesson, students are subjected to harsh punishment. The student, dressed in a tight gym uniform that highlights her snug bloomers, is restrained onto the teacher's desk, where the session begins immediately. The teacher uses mops and brooms not as whips, but as vibrating toys to torment her. Overwhelmed by this depraved passion, the student is consumed by humiliation and pleasure, screaming as she reaches climax, convulsing repeatedly in trembling spasms.
