A power dynamic shifts as a mistress takes control, her eyes gleaming with sadistic pleasure. She commands her submissive, "Grab your cock, slave. You will masturbate for me, and when you cum, you will not waste a drop. You will follow my instructions precisely." The sub, eager to please, grips his throbbing member, his strokes steady and firm. The mistress, enjoying the show, leans back, her fingers tracing the edge of her lacy bra. "Faster," she demands, her voice a whip crack. "And remember, you will not cum until I say so." The tension builds, the air thick with the scent of sex and the promise of release, but only on her command.
