The clinic's cold, sterile air does little to dampen the heat between Dr. Isaac and his patient, Brian. Isaac's experienced hands roam Brian's body, pausing to squeeze his firm ass. Brian moans, his cock twitching as Isaac slides a finger into his tight hole, twisting and pushing deep. Isaac's own bulge grows, craving more, but he maintains professional composure, ensuring Brian's 'oral exam' is thorough and satisfying.
