Adult university student Shiori visits a lender to cover the debt she ran up at a host club, but she has not repaid her previous loan. The man demands an obscene video as payment, making her describe her masturbation, hairy anus, swollen clit, and worthless pussy on camera. He then introduces her to an escort owner for masochistic service training before filming more dirty-talk sex, gradually conditioning her into a verbal sex doll.
