To repay a debt she's been hiding from her husband, young wife Himari visits a certain office. However, when no way to repay the debt is found, the man gives her a harsh ultimatum: "You'll have to pay it off with your body by starring in a dirty talk video." She is then subjected to training sessions on dirty talk blowjob techniques and nipple play conducted by a brothel owner, followed by instruction in dirty talk sex. As Himari's body and mind are tormented with lewd words, she gradually finds herself drawn into this obscene world. Through this process, she discovers an entirely new side of herself.
