A nervous twink, new to gay sex, finds himself in a clinical setting, his heart pounding as he undresses. The doctor, a muscular, hairy top, applies generous amounts of lube to his thick, veiny cock. The twink's eyes widen at the sight, his own dick twitching in anticipation. The doctor gently probes the twink's virgin ass, spreading the cheeks wide, before slowly pushing in. The twink gasps, feeling the intense pressure and stretch, but soon finds a rhythm, moaning as the doctor picks up speed, fucking him hard and deep. The scene is raw, greasy, and explicit, capturing the twink's first time taking a hard cock up his ass.
