A hentai trainer's world turns upside down when her students decide to teach her a lesson. Dragged into a seedy backroom, she's stripped and spread, her ample curves on display. The first cock slides into her unlubricated ass, making her wince, but the real torment begins when a second joins, stretching her tight hole beyond its limit. The trainer's cries are drowned out by the grunts and slaps of flesh as her students take turns ravaging her, filling her holes and marking her as their toy.
