Dr. Old Guy, experienced and stern, examines his young, lithe patient, a twink with a tight, smooth body. The doc's professional demeanor belies his lurid intentions as he runs his hands over the twink's chest, tracing his abs, and lingering on his firm, round ass. The twink, nervous but willing, responds to the doc's touch, his cock tenting his scrubs. The doc, noticing the bulge, smirks, 'Let's get a closer look at that, shall we?' He proceeds to 'examine' the twink's cock, sucking it expertly, before bending the twink over and lubing up his tight hole for a thorough, deep probing with his own thick cock.
