Naive, straight twink Tim, new to this gay doctor's office, finds himself in an unexpected situation. The doctor, a handsome, experienced gay man, starts the appointment normally, but as Tim undresses, the doctor's gaze lingers. Tim, confused and aroused, feels his cock hardening. The doctor, noticing, takes advantage, asking Tim to stroke himself for a 'medical check'. Tim hesitates, then tentatively begins, his first time with another man.
