In the sterile, clinical setting of a gay clinic, a smooth twink is subjected to a rigorous physical examination by a horny doctor. The doctor, captivated by the twink's innocent beauty, can't help but let his professionalism slip. He lubes up a thermometer and teasingly slides it into the twink's tight ass, causing the boy to gasp and clench. The doctor, now rock hard, decides to take the exam to the next level, revealing his own throbbing cock to the eager twink.
