Convenience-store clerk Aoi is cold and defiant toward both customers and her manager, though she is affectionate with her coworker boyfriend. Resentful of the contrast, the manager seizes his chance when a blackout locks every door for 24 hours. He forces his enormous cock down her throat, brutally pounds her deepest spot, and makes her perform oral sex in exchange for food. When a repairman finally arrives, he is dragged into the assault as well, leaving Aoi penetrated around the clock until she is soaked and convulsing through uncontrollable orgasms.
