A trembling slave, bound and gagged, is presented to his Mistress, eyes darting nervously between her stern gaze and the pulsating bulge in his chastity device. She strokes his cheek, "You've been such a good boy, haven't you?" Her hand wraps around his caged cock, giving it a gentle squeeze. "But it's time for your reward, and your punishment." She unleashes his throbbing member, commanding him to stroke it while she watches, her breath growing heavy. His humiliation complete, she denies him his climax, locking him back up, leaving him aching and desperate.
