The clinic's back room becomes a den of debauchery as the doctor, his professional demeanor replaced by primal hunger, lubes up his thick, veiny cock. The twink, his asshole twitching with anticipation, braces himself as the doctor enters him, inch by inch, stretching him wider than he's ever been. The doctor's hips slap against the twink's ass, the sound echoing in the room as he pounds him mercilessly, their moans of pleasure mixing with the scent of sweat and sex.
