A strange love triangle between a small-breasted, shaved high school girl, a middle-aged janitor, and a middle-aged teacher. Mikako, a high school girl, is in a physical relationship with her middle-aged teacher who is the head teacher of her grade. One day after school, she accidentally witnesses the janitor masturbating to her school swimsuit in the classroom. Although she is surprised, Mikako, who has always liked older men, does not feel uncomfortable and instead asks him to "take a good look at a man masturbating." The small-breasted high school girl is used as a toy by the old men, but she gets lewd and wild in this forbidden face-licking affair after school.
