Aoi Amano works at a convenience store and secretly dates a coworker, hiding the relationship from their nasty manager. One day he catches her snacking on store merchandise and begins humiliating her by repeatedly fucking and marking her with creampies. She resists at first, disgusted by him, but he pounds her raw and forces so many embarrassing orgasms out of her that the pleasure gradually takes over. What should have been the worst sex imaginable leaves her increasingly conquered and unable to resist.
