Yuna, a housewife whose marital life had cooled down, had an affair with a student she met at a convenience store at a part-time job, and became so crazy about sex that they sought each other's bodies during work. She hides in the shelf and gives blowjobs so that customers don't find out, and she spends her days in the warehouse and toilets in the store so that the store manager doesn't find out. She finally decides to break up with her husband and Yuna begs her partner to cum inside her.
