In the dimly lit bedroom, Mistress Kares clears her throat, commanding her sissy step-brother to her feet. He obeys, eyes downcast, as she inspects his pathetic excuse for a cock. "You will not touch yourself until I say so," she growls, her voice dripping with domination. He nods, hands clasped behind his back, erection throbbing. She smirks, enjoying his humiliation, and begins her cruel, tantalizing instructions. "Stroke slowly...faster...now slower...you're pathetic," she sneers, her voice echoing in the room filled with his desperate moans.
