Bound and helpless, the submissive finds himself at the mercy of his Mistress's whims. She explores his body with toys, tracing the sensitive underside of his shaft, cupping his balls, and occasionally brushing his tip, sending shivers of anticipation through him. The chastity device clicks shut, trapping his hard cock, as she commands, 'You will not cum until I allow it.' The struggle for control is palpable, the tension electrifying.
