A girl in a navy blue sailor uniform faces the camera, comparing herself to a man. She allows him to grope her still-developing breasts, her eyes fixed on the lens, filled with curiosity and anxiety. Facing financial hardship, the girl pleads for the man to buy her underwear. Instead, he proposes to buy her herself. The deal is struck for just a few thousand yen. In exchange for a small sum of money, the girl resolves to offer her body. In the dark confines of a public restroom in a park, the man spreads the tearful girl's legs and slowly penetrates her.
