The doctor's eyes gleam with mischief as he snaps on a new pair of gloves, the latex squeaking enticingly. He lubes up his fingers, running them along the twink's inner thigh, making him shiver. The doctor's touch is firm yet gentle, his fingers tracing the twink's balls, his shaft, before finally wrapping around his cock. The twink gasps, his hips bucking involuntarily as the doctor strokes him, his thumb rubbing circles on the sensitive head. The doctor leans in, his lips brushing against the twink's ear, "And how about your oral reflexes?" he whispers, his hot breath sending shivers down the twink's spine.
