The doctor, a seasoned gay professional, begins the routine check-up, his experienced hands skimming over the twink's smooth skin. He pauses at the twink's crotch, feeling a distinct bulge. The twink blushes, trying to hide his arousal, but the doctor just smirks, "Well, let's have a look at that, shall we?" He unzips the twink's shorts, revealing his hard, throbbing cock. The doctor, with a professional yet tantalizing touch, strokes the twink's cock, feeling its heat, as the twink gasps, giving in to the pleasure.
