In a bustling gay clinic, a curious twink patient is about to get more than just a routine check-up. The young, naive twink is led to an exam room by a handsome, authoritative doctor. As the doctor begins his physical, the twink's eyes widen with surprise and excitement when the doctor suddenly pulls out a thick, long thermometer, not the usual kind. The doctor, enjoying the twink's astonishment, slowly inserts the unusual thermometer into the twink's tightly-clenched hole, making him gasp and squirm with a mix of pleasure and unexpected pain.
