A plus-sized submissive, brimming with self-doubt, is guided into a femdom chamber by her stern mistress. The mistress, clad in leather, delights in her prey's discomfort, calling her "fat" and "disgusting." She orders the submissive into a chastity device, her large frame trembling with humiliation. The mistress, enjoying her power, torments her with descriptions of her ample curves, making the submissive squirm and blush.
