Kneeling before her, the slave's chastity device glints under the dim light. The femdomme, resplendent in leather, commands him to surrender his cock and balls to her. She strokes his shaft through the metal cage, feeling his futile attempts to harden. "You will not cum," she purrs, "not until I allow it." Her firm grip and slow, steady rhythm drive him wild with need, yet he knows better than to disobey. She milks his balls, watching his face contort with the exquisite torture of denial.
