Her mother vanishes after leaving enormous debt and a letter with a phone number. Rin calls, follows the stranger's instructions to an address, and discovers she has apparently been sold to a fat middle-aged man. The adult uniformed-girl role is restrained and helpless as he licks, penetrates, and takes her first bareback creampie. Cries for her mother bring no rescue; thick older semen repeatedly fills her womb while her slender body convulses and arches through thrusting orgasms that expose the masochism beneath her pristine appearance.
