Aoi works part-time at a convenience store frequented by her sexless husband, and she is tired of seeing him both at home and at work. Then a kind young man named Tatsuya joins as a junior coworker. Attracted to everything her husband is not, she invites him out for welcome drinks, and the two begin a sexual affair. They keep meeting inside the store during work and breaks, squeezing dense sex into every short window, until merely clocking in makes Aoi wet.
