Proper wife Mio Kijima, who works full-time part-time five days a week with her husband, was secretly called to public restrooms by a middle-aged man from her part-time job after work. 'I think I can manage the raise for you, Ms. Kijima...' Lured by these words, the part-time wife is gang-banged in the station toilet. Her husband, who knows nothing, is genuinely happy about his wife's raise, but she gradually falls both physically and mentally due to the daily acts.
