Ruby, a British beauty with a penchant for femdom, takes command of her submissive's pleasure, acting as his key-holder. She trains him in the art of orgasm denial, her voice a sultry, commanding whisper. "You'll only cum when I say so," she orders, her fingers tracing the outline of the chastity device keeping his erection at bay. She edging him mercilessly, bringing him to the brink of release, only to cruelly deny him, leaving him desperate and begging for her mercy. Yet, Ruby's not one to give in easily; she enjoys her power too much.
