A dominant woman asserts control over her submissive partner, commanding them to masturbate while she watches in a voyeuristic power trip. The submissive, bound and helpless, strokes their throbbing cock until they're on the brink of orgasm. But their mistress has other plans. "You'll only cum when I say so," she taunts, making them suffer through denied climaxes. Finally, when she deems them worthy, she allows the release, ordering them to taste their own cum in a degrading act of submission.
