That was when she saw that her bull terrier had a hard-on. He was sitting in the passenger seat, and his cock jutted up like a cantilever supporting him.

The traffic light was still red.

The head of the dog's cock was just as red.

Judy glanced around and, seeing no other cars about and no pedestrians, she grinned and reached out, taking her dog's cock in her hand.

The dog whimpered gratefully.

Judy began to stroke his prick.

The big, hard cockshaft swelled into her fist, and the knob began to pulsate. Judy got plenty excited, playing with the animal in public. Her fist flew up and down at a great rate, skimming his prick, dragging the furry pelt up and down the throbbing prickstalk. She knew that the dog was going to shoot his hot wad very quickly. She lifted the hem of her skirt so that it would not get soaked with jism. She leaned towards the beast, her fist pumping steadily.

The dog's cock went off like a fire hose in her hand.

The first creamy spurt flew straight up in the air and hung suspended for a moment, then dropped down, splattering on her naked thighs. She continued to pump away, emptying his cum-loaded balls in spurt after spurt.

"Nice?" she asked.

"Wowf," said the dog.

The light was green. Judy wiped her hand delicately on a Kleenex, put the car in gear and drove off. It had been no momentous occasion for the girl since she was well accustomed to masturbating her pet.

Little did she know the profound effect that her act was to have on a total stranger who had been watching from a window above.

CHAPTER TWO

Jenny Baker hadn't come that morning. That was one of the reasons why she had gone to the office on a Saturday morning, figuring that she could get her mind off her pussy by finishing up a bit of extra work over the weekend.
