In a clinical setting, a dominant doc takes control, her patient's cock the center of her medical attention. She watches, unblinking, as he tentatively touches himself, her presence commanding obedience. She guides his hand, her fingers brushing his, her breath hot on his ear. The room is filled with the scent of sweat and desire as she orders him to tug harder, faster, her voice a whip's crack. His cock glistens with pre-cum, his balls tighten, and she grins, knowing she's in control as he nears the edge, her orders echoing in his mind.
