Story: The story opens with a nightmare, in which several girls take Momone's underwear off and make a display of her to the boys. Apparently, this was something that actually happened when Momone was a student. Now, she is a high school teacher, and all the male students lust after her because of her good looks and sexy body. Hino, a juvenile delinquent, is also attracted to her, and one day, he dares to visit her apartment. Hino succeeds in seducing her and makes her beg for sex. Unable to control her sexual desires, Momone even agrees to become his lover.
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.
