The pup's kinky transformation complete, he's collared and leashed, his body bound in intricate rope work, leaving only his ass accessible. The Dom wastes no time, his cock hard and ready. He lubes up, pressing his slick head against the pup's tight hole. With a swift thrust, he's inside, fucking the pup slowly at first, then building speed, his hips slapping against the pup's ass. The pup, submissive and eager, takes it all, his body writhing in pleasure, his cries of "More, Sir!" echoing through the room.
