A bratty submissive, locked in a chastity device, is paraded around in public as part of her punishment. The humiliated slut is forced to follow her mistress's every command, even as they walk through a crowded marketplace. Her chastity device is locked tight, denying her any pleasure, and her mistress ensures she's dressed in a way that draws the most attention to her predicament. The submissive's humiliation is complete when she's made to thank her mistress publicly for her 'mercy'.
