My father-in-law, Kojiro, who came to Tokyo to get a chef's qualification, will teach his wife, Iroha, how to cook. As Kojiro continues to teach her, Kojiro's body touches increase, and Iroha feels a burning sensation in her body. Because she doesn't have a relationship with her husband, she can't stand it and masturbates in the bathroom, but she is seen by Kojiro. Her husband's violent and obscene sex makes Iroha's crotch uncontrollable, and her body becomes more and more sensitive to the humiliation of her father-in-law who doesn't know how to stay.
