A college girl named Shiori visits a consumer finance company to repay her debt, but confesses that she's already behind on her previous payments. The man pressures her, saying, "The only way is to film a dirty-talking video and pay with your body." Shiori begins to speak perverted words on her own—"I want lots of people to watch me masturbate," "There's a lot of hair growing around my anus," "My slutty clit is getting hard," "Please fuck my trashy pussy." Shiori strings together obscene phrases in front of the camera. The man then introduces her to a brothel owner, saying, "If you work in the sex industry, you can earn more." After putting her through an M-sensual massage parlor training session, another dirty-talking sex video shoot takes place. The film vividly depicts Shiori being gradually brainwashed and trained into a dirty-talking slut through verbal abuse.
