The submissive's cock twitches eagerly, yearning for her touch. The mistress grins, her eyes locked onto his as she slowly brings her hands close, but never quite touching. "Only when I tell you," she repeats, her voice a sultry whisper. She leans in, her breath teasing his ear, her words sending shivers down his spine. "Jerk off for me, pet," she finally commands, her voice laced with dominance. His hand moves, stroking his cock, following her every instruction, lost in a world of pleasure and submission.
