In this gay sexual encounter, a straight man finds himself in a doctor's office, but not for the usual check-up. The handsome, experienced doctor, surrounded by erotic posters, offers a unique service - a prostate exam, but not as the patient expects. The doctor, joined by another man, begins with a gentle touch, exploring the straight man's virgin ass. The straight man's initial hesitation fades as pleasure takes over, his cock hardening in response. The doctor, enjoying the power dynamic, teasingly edges his patient, refusing full penetration until the straight man begs for it. Finally, the doctor pummels the straight man's bung, fucking him hard while the other man watches, stroking his own cock.
