Reira was a famous slut in her hometown. But now she is a devoted wife who is devoted to her husband. One day, she is persistently approached by a man trying to sell her, and it turns out to be Tatsuya, a local classmate who knows her past and who used to be a playboy. Unable to refuse Tatsuya's request, she starts working at a delivery health service, satisfying the sexual needs of old men, and is reminded of the pleasures of her past as a slut. Tatsuya escalates and embraces Reira roughly, just like in the old days. While thinking that her husband must not find out, this married woman becomes increasingly addicted to the pleasure of being violated by sadistic men.
