The gay clinic is buzzing with activity, and Dr. Zack is on call. Today's patient is a cute twink, eager for some medical attention. Standing to the side, Dr. Zack takes the twink's knob in his gloved hand, feeling its length and girth. The twink's cock twitches, and Dr. Zack can see the pre-cum glistening at the tip. He knows exactly what this patient needs, and he's more than willing to provide it, right there in the clinic.
