I make slave jerk off and cum while I beat his balls

A dominant brunette grants her slave a single indulgence: the chance to climax. But there’s a price—he must stroke himself to orgasm while she relentlessly assaults his balls, delivering sharp punches and crushing squeezes. Just as he reaches his peak, she tightens her grip, driving her fingers deep into his swollen sack to steal the pleasure. His desperate pleas for mercy go unanswered as she refuses to release him.
