A submissive man, eager to please his dominant partner, offers himself for chastity training. She accepts, presenting a cock cage that will deny him orgasmic relief. With practiced ease, she applies lube, her fingers caressing his sensitive flesh before guiding the cage onto his throbbing cock. The tight fit makes him gasp, but he remains still, waiting for her approval. She snaps the lock shut, her eyes sparkling with satisfaction as she informs him, "You won't come without my permission now."
