The doggy could sense that – could scent and taste her rising urgency, her smoldering need. Perhaps, with some bestial instinct, some doggy wisdom inherent in his genes, the brute realized that the girl was in no condition to resist his further advances, that all doubts and inhibitions had been melted in the fiery heat of her arousal.

His tongue wedged into her, plowing up her soaking fuck tunnel, boring deep into her loins. Karen moaned and panted, trembling as the waves began to lash her belly and dart up her thighs.

Suddenly Rover's tongue was gone.

"Don't you dare stop!" she wailed, jerking her ass up and looking back over her shoulder.

Rover was crouching behind her, his hind-quarters lowered, his tail lashing and his teeth bared. For an instant, they gazed into each other's eyes. His amber orbs were glowing as if an inferno was raging within his skull, and looking under him, she saw that the swollen head of his massive prick was glowing even brighter. That naked red slab looked like an incandescent light bulb on the end of his hairy black cock.

Then Rover sprang.

His chest hit her ass and his front paws wrapped firmly around her hipbones, dragging her back towards him. He was mounted on her ass like a gargoyle on a wall, clinging to her haunches tenaciously. The great lever of his prick was standing upright, the underside pressed against the crack of her ass and his knob dripping down his hairy stalk.

Holy shit! He wants to fuck my cunt! Karen realized, gasping at the thought.

Rover's hindpaws scrabbled on the carpet and his flanks rippled and heaved. He humped, his powerful haunches slamming out and driving his prick against the back of Karen's thigh. She felt his smoking hot prick bump against her, dribbling slime down her leg.

The brute humped again, missing the hairy target in his frantic attempts. This time his cock-head rebounded from the cheek of her ass. The doggy, frustrated by being mounted with his cock still unburied, whimpered.
