A horny doctor, craving forbidden fruit, invites a straight, muscular patient for a 'check-up.' The unsuspecting man strips, revealing his impressive, uncircumcised cock. The doctor, unable to resist, begins a thorough, tongue-in-cheek examination, sucking and stroking the patient's growing erection. The patient, initially shocked, soon surrenders to the pleasure, fucking the doctor's face and ass in exchange for a clean bill of health. They cum together, the doctor's seed mixing with the patient's, marking their taboo transaction.
