Aoi works part-time at a convenience store. Her husband (sexless) is a regular customer, and she's been getting a bit tired of seeing him both at home and at work every day. Then, a young man named Tatsuya becomes her coworker... Unlike her husband, Aoi is drawn to the kind and young Tatsuya. She invites him out for drinks under the pretext of a welcome party. From that day on, the two begin an affair limited to the workplace... They repeatedly have sex in the store, regardless of whether they're on duty or on break. Before long, Aoi finds herself getting wet just from punching out her time card...
