Pain and pleasure in a BDSM couple's encounter

The scene begins with a couple engaging in a BDSM encounter. The woman, a Mistress, is in complete control of her partner, who is being punished and dominated by her. She starts by giving him a handjob, but instead of enjoying it, he moans in pain as she uses her hands to damage his genitals. The Mistress continues to dominate her partner, using her body weight to push him into submission. She then takes control of his orgasm, denying him a proper one as she ruins it with her own moans and screams. The man is clearly in pain and discomfort, but the Mistress continues with her punishments, making sure he is completely submissive to her. The scene ends with the man finally achieving an orgasm, but it is a painful one, made worse by the Mistress' dominance and control.
