A young, lean twink, nervously undresses for his mysterious gay doctor. The doc, with a gleam in his eye, produces a long, cold steel rod. "This will help with your... unique condition," he assures, positioning the lad on his back. The twink gasps as the rod presses against his smooth, hairless balls, then slides into his tight, unlubricated asshole. The doc, now visibly aroused, begins to push it deeper, drawing out the young man's pain and pleasure.
