His cock stayed soft, and Karen got angrier even as she became more frustrated. She sat back on her heels and gave him a look of utter scorn. He looked back abjectly. Her tits were dripping with congealing jism, and streaks of the creamy stuff were matted in her jet-black cunt bush. Ribbons of slime ran sluggishly down her smooth thighs.

Tony couldn't blame the horny girl for being angry. His shame increased. He could no longer bear to face her after his failure, to see the horrible frustration in her eyes.

He gave a helpless little shrug and stood up on trembling legs. He tucked his limp cock and deflated balls back into his fly and zippered it up. He paused for a moment, but when Karen said nothing, he shrugged again and walked toward the door, blushing with embarrassment.

"Well – so long," he said, and he went out.

Rover was still standing in the hallway, his white fangs gleaming in the dim light, and Tony muttered, "Nice doggy, good boy," rather nervously as he turned sideways to edge past the formidable beast. He had a horrible idea that Karen might command the brute to sink those sharp fangs into his useless cock out of spite.

Eyeing those jowls, Tony failed to notice that Rover had an enormous hard-on.

And although he did notice that long, wet, red tongue lolling from the dog's jaw, he made no connection between that and Karen's neglected and frustrated cunt.

He went out and closed the door.

Rover stood in the hallway, ready and willing, and waiting for a command.

In the front room, Karen was not thinking about her dog yet. But she was still kneeling on the floor and, although she didn't realize it in her despair and frustration, she had assumed a position that was very familiar to a dog – the doggy fucking position!
