"Oh King, that was lovely," Mary said with a sigh as she got up. Then she went to crouch beside him on the carpet, a hand under him, grabbing his big prick and giving it a slow jerking, though she doubted that he needed to be set up to fuck her.

"Yes, King, you like it when Mommy plays with your big cock, don't you? What a lovely cock you have, you big beauty. It feels so good when you're ramming that beautiful prick up my cunt and fucking me. Are you all set now, lover?" she asked as she looked and saw the wet, red cock sticking out of the sheath and decided it was time to play bitch with him, to get down on all fours and give him her ass to ride and her hot cunt to fuck.

Releasing his cock, she smiled, patting the big animal on the head; then she was kneeling so that she could watch their reflection in the full-length mirror while he fucked her. The animal showed how well he had been trained by sitting obediently, his eyes feasting on her naked body until she gave the command for him to come and fuck her.

He got to his feet at once and bounded across the room to her. As he reached her, he took just one sniff of her cunt, then he mounted his human bitch, wrapped big paws around her and began jabbing a cock which grew alarmingly as the sheath peeled all the way back off his cock, a cock which was almost what Mary had called it – man-sized.

Looking in the mirror, a profile view, Mary saw the big prick jabbing the air and loved the sight of it, thrilled to the sight of the big cock and the excitement of her dog; then the tip of his jabbing prick touched the edge of her cunt and Mary braced herself for what was to come.

The animal paused, she heard him panting, then he jabbed again, and this time his cock went straight and true, right up her cunt. There was never anything at all tentative about King. That first jab of his cock invariably sent at least half its length up her hole, and then he was panting as he fed the rest of it into her and made her know that her cunt was full of stiff cock.
