She twisted her hips, winding her juicy slot around on the big slab of his knob and rubbing it against her frenzied fuck button.

"Pour it to me, Rover," she gasped. "Oh, shit – pump that prick up my cunt, boy! I want it! Give it all to me – give me every fucking inch!"

Rover's big, muscular body stiffened, his hindquarters tensed, ready to plunge, and his tail flicked up and down. His front paws dragged her back by the hips, and with a joyous yelp, he plunged his prick into her.

His long, thick fucker went in balls-deep with the very first thrust. Karen gasped. Rover held it up her fuckhole for a moment. He was thrilling to the pure ecstasy of having every inch of his big prick buried in her steaming cunthole and Karen gurgled with the joy of having her creamy cunt stuffed to the brim with throbbing cock-meat.

Her cuntlips were wide open, plastered around the hairy roots of his prickshaft. Frothy cuntjuice oozed out and ran down onto his swollen balls.

Karen had never known such bliss, had never before had such a wonderful cuntful. Oh, how glad she was that she had decided to fuck with the dog! She knew now that she was not going to feel any regrets. It was far too wonderful for any misgivings.

He clung to her haunches, panting. His weight pressed her ass down, and the rock-hard lever of his cock tilted her crotch up at the same time. She was mounted by a dog! It was an animal prick pounding in her fuckhole! The dark knowledge of her depravity added a new dimension to the physical thrill of the throbbing penetration, the bestial coupling.
