In the sterile, clinical setting of an underground gay clinic, a young twink nervously awaits his examination. The doctor, a rugged, experienced man, enters, donning a rubber glove. He begins the check-up, his touch firm yet gentle, exploring the twink's body with a clinical precision that belies the arousal growing in his pants. The twink squirms, his breath hitching as the doctor's gloved hand brushes against his hardening cock. The doctor, sensing his patient's excitement, smirks, "Well, it seems we've found the source of your discomfort."
