The Mistress's voice echoes through the room, a sultry symphony of dominance. "Stroke yourself," she commands, her eyes locked onto her submissive's every move. He hesitates, then begins to obey, his hands tentatively wrapping around his hardening cock. She watches, her expression inscrutable, as he picks up speed, his breathing growing ragged. "Harder," she demands, her voice a whip crack. He complies, his body tensing as he nears the edge, his hands moving furiously at her command.
