A top student experiences vaginal discharge, saliva, and sweat during orgasm, resulting in ecstasy. (This is followed by unrelated text: "DASS-564 Nagano Suzu, using aphrodisiacs for on-campus sex.")

Homeroom teacher Saito helps transfer student Nagano Suzu, who is entangled with delinquents. "If you have any trouble, please talk to me," Saito says, approaching Nagano. However, under the guise of caring for his students, he is actually a problem teacher who repeatedly takes photos of female students and sexually harasses them. Saito then turns his gaze to the model student, the quiet Nagano, and uses an aphrodisiac to admire her crotch. "I don't like it, I resist it, but my body doesn't understand why, and I eventually ejaculate." He uses this situation as a joke, threatening Nagano to soak him in an aphrodisiac and train him to become a sex urinal.
