Mark Something, a young twink with a persistent erection, visits Jesse Zeppelin, the burly doctor, for an examination. Jesse, intrigued by Mark's predicament, decides to take a hands-on approach. He begins with a thorough inspection, running his large, strong hands over Mark's smooth body. Mark's cock twitches in response, and Jesse, noticing, smirks. He takes Mark's cock in his hand, stroking it gently, then firmly, before taking it into his mouth. Mark's hips buck, and Jesse chuckles, enjoying the control he has over the twink. He then bends Mark over, lubing up his thick cock before plunging it into Mark's tight hole, fucking him bareback until they both explode in pleasure.
