A line of tall, muscular men, clad only in white briefs, await their turn in the cold, clinical room. The doctor, a stern figure in his crisp lab coat, calls them in one by one, each man's body tensing as he's ordered to strip. Penises of varying sizes and shapes are revealed, some soft, some already hard with anticipation. The doctor checks pulses, examines skin, and probes gently, his professional demeanor belying the sexual tension in the air. As he leans in close to examine one twink's perfectly symmetrical balls, the man's cock twitches, betraying his excitement at the doctor's touch.
