Hinako is a young wife burdened with secret debt unknown to her husband. To repay it, she visits an underground loan shark. However, when she says she still can't repay the money she borrowed before, the man pressures her, saying, "The only option is to film a dirty talk video and have you pay with your body." Thus, Hinako is forced to appear in a doujin AV as collateral for her debt. Asked, "It's not coercion, right? It's your own will, right?" she meekly replies, "Yes..." The man begins dirty talk training, and further introduces her to a brothel owner, saying, "You could earn more if you work in the sex industry." M-sexual technique lessons and dirty talk sex lessons are conducted, and Hinako is brainwashed into obscene verbal abuse.
