Sierra Sanders, dressed in her crisp nurse's uniform, welcomes Lance Hart into her office, her eyes twinkling with a mix of professionalism and mischief. She guides Lance through a series of medical examinations, her hands expertly exploring his body, her touch both clinical and intimate. As she reaches his groin, she expertly handles his cock, her gloved hands working in tandem with her medical knowledge. She instructs him on the art of CBT, her voice calm and steady as she guides him through the sensations of pleasure and pain. Lance, both aroused and apprehensive, follows her instructions, his body responding to her touch, his cock growing harder with each expert maneuver.
