Derek, a fresh-faced twink, finds himself in the throes of a vivid fantasy as Dr. Geo, the rugged, experienced gay medic, examines him. The crinkle of the paper gown, the coolness of the stethoscope on his chest, each sensation sends jolts of pleasure through Derek's body. Dr. Geo, his deep voice resonating, asks Derek to lift his gown, revealing Derek's hardening cock. Derek blushes, but the doctor's professional facade cracks, a hint of lust in his eyes. As Derek's cock throbs, Dr. Geo leans in, his warm breath on Derek's ear, "You're responding quite well, Derek," he murmurs, sending Derek over the edge, his cock pulsing with desire.
