Ayumi works at a public bathhouse but is falsely accused of stealing a wallet. The truth is, the bathhouse owner has set a trap to sexually dominate her. She is subjected to a body search by the owner, who gropes her entire body. Gradually losing resistance, she is eventually raped by him. Forced into submission under the condition of receiving money, Ayumi is led by a collar and chain into the men's changing room, where she is ordered to provide sexual services to customers. One after another, men violate her as she trembles with humiliation and pleasure, her pussy dripping wet from relentless thrusting. Her big tits sway as she succumbs to pleasure, climaxing repeatedly with a look of satisfaction on her face.
