The doctor's uniform rustles as he undresses, revealing his lean, tattooed body. He's got a secret, a kinky twist to his medical practice. He pulls out a thick, veiny dildo, a perfect match to his own cock. He's going bareback today, no lube, just the natural lubrication of his hungry ass. He presses the head of the dildo against his hole, pushing it in inch by inch, his breath hitching with each thrust. His ass stretches, accommodating the toy, as he fucks himself, his hand moving faster, his moans growing louder.
