Yuna, a housewife whose marital life had grown cold, entered into an affair with a student she met at her part-time job at a convenience store. They became so obsessed with sex that they would engage in it during work hours. Yuna would hide behind shelves to give blowjobs without being caught by customers or sneak into the store's storage room or restroom to have sex without the manager finding out. Eventually, Yuna decided to separate from her husband and begged her lover to ejaculate inside her.
