A curious gay doctor, known for his unconventional methods, invites a straight patient for a "routine check-up." The patient arrives, towel-clad, to find the doctor already aroused. "I need to take your temperature," the doctor purrs, "but I must do it... differently." He maneuvers the patient onto his side, spreading his legs, and inserts the thermometer into his ass, twisting it slowly. The patient's initial resistance melts away as the doctor's skilled fingers work their magic. The doctor's lust grows, his breath hitching as he removes the thermometer, replacing it with his hungry mouth, licking and teasing the patient's now eager hole, preparing him for what's to come.
