Taking charge, Hino manipulates Momone, demanding that she come to school without any underwear on. Alone in a room, he applies some sort of stimulating lotion to Momone. He goes on to declare that she is a masochistic flasher and he'll prove it in the class. Sure enough, during their art class, Momone ends up not only showing off her private parts to the male students but also masturbating in front of the entire class -- fainting as she reaches her sexual climax.
When Momone's returns to consciousness, she finds herself alone with Hino, who has already inserted a vibrator inside her and dressed her in skimpy sex gear. Hino takes her to the other boys, who are waiting to have fun with her. She ends up giving oral sex to them and demands that they give it back. In the end, she passes out as Hino shows up to take her away.
