The doctor's hands tremble as he wraps them around the twink's firm, uncut cock. He strokes it gently, feeling it throb and grow harder in his grasp. The twink's breath hitches as the doctor leans in, his tongue flicking out to taste the pre-cum beading at the tip. He sucks the head into his mouth, swirling his tongue around it, before taking the entire length down his throat. The doctor groans, his own cock leaking profusely. He pulls out a bottle of lube, slicking up his cock before pressing it against the twink's tight hole. The twink gasps, feeling the doctor's thick sausage push inside him, filling him completely. The room echoes with their moans and the sound of flesh slapping against flesh as the doctor pounds the twink's ass, bringing them both to a satisfying, messy climax.
