Honoka and her husband live in the company housing. Her husband's former boss, Tajima-san, also lives next door. Tajima's wife passed away a year ago, and he is unable to move around normally, so his superiors want Honoka's husband to help Tajima. Seeing this as an opportunity for advancement, Tsuji asks his wife to take care of the boss while he goes to find a nurse. Because it has been a long time since they have been intimate, and he meets a very beautiful, busty, and seductive girl, Tajima takes advantage of Tsuji's promotion to threaten and force Honoka to serve his sexual desires.
