In a dimly lit clinic, first-timer Derek, a lanky twink with a nervous smile, awaits his gay doctor. The doc, a rugged hunk, greets him warmly, eyes lingering on Derek's tight body. He begins the 'exam,' running his hands over Derek's smooth skin, making the twink's cock twitch. Derek's eyes widen as the doc pulls out a massive, throbbing erection. "Ever seen one this big, Derek?" he growls. Derek shakes his head, mesmerized. The doc lubes up and pushes his cock against Derek's virgin hole, making the twink gasp. "Ready for your first time, Derek?" he grunts. Derek nods, eager, and the doc slides in, giving Derek his first raw butt experience.
