Mio works hard as a call girl to pay off her debts without her husband knowing, but she also feels annoyed by the carefree residents of her apartment building, and whenever they meet she finds fault with them to relieve her stress. However, one of the residents finds out about her call girl job, and as revenge he calls her out to him and makes her have sex with him. It doesn't end there, and another resident who has a grudge against Mio is called in and she is forced to serve as a cock slave in front of the two men, having her pussy penetrated repeatedly and reaching orgasm many times.
