In the sterile, white-walled clinic, the young twink lies back on the examination table, his heart pounding. The gay doctor, dressed in a crisp white coat, approaches, his eyes scanning the twink's body. He starts with the basics, stethoscope to chest, blood pressure cuff on arm. But his touch lingers, his fingers brushing against the twink's nipple, his hand wrapping around the twink's wrist. The twink swallows hard, his cock stirring. The doctor smiles, a knowing look in his eyes. He reaches for the lube, squirting some onto his fingers. 'Let's check your prostate,' he says, his voice casual. The twink nods, his breath catching as the doctor's fingers push inside him. The doctor works his fingers in and out, his touch firm, confident. The twink's cock tents the paper sheet beneath him. The doctor leans in, his lips brushing against the twink's ear. 'You're very responsive,' he murmurs, his fingers moving faster. The twink moans, his body arching, lost in the sensation of the doctor's touch.
