I’m a perpetually overworked employee under a harassing boss. One day, I’m reprimanded by Hinata Tachibana, a married woman from the general affairs department, for exceeding working hours. However, there’s a secret behind her serious demeanor… she’s actually extremely horny and had been masturbating at work. Upon discovering this, I’m called by her and seduced into an affair. From that day on, I’m treated as a sex toy, exploited both at work and at home.
