With a mischievous glint in his eye, the doctor leans in, his breath hot on the twink's ear. 'Bend over, let me see that ass,' he commands. The twink complies, his heart pounding as he feels the doctor's hands on his cheeks, spreading them wide. The doctor runs a finger along the twink's virgin hole, causing him to shiver. 'So tight,' the doctor murmurs, before pressing the head of his thick cock against the twink's entrance. The twink braces himself, feeling the doctor's cock slowly work its way into his ass, filling him completely. The doctor begins to move, his hips thrusting forward, fucking the twink with deep, powerful strokes, his hands gripping the twink's hips tightly.
