Scotty barked several times and poked his snout against the girl's pussylips. They were thickly coated with glistening cunt juice.
Suddenly, Biff pulled the vibrator all the way out of his sister's pussy.
"Nooo!" she wailed.
"Easy, bitch, just you wait," Biff said.
He held the juice-coated vibrator under the dog's nose.
"Here, smell it, boy. Doesn't that smell good?"
The animal barked again. His tail thumped against the top of the table. His cock grew redder and stiffer.
"Go on, Scotty, help yourself!" Biff urged.
The dog poked his furry head between the spread legs of his mistress. Gail felt droplets of steaming dog-drool spilling onto her crotch. She quivered with anticipation. Next, she felt the dog's warm breath on her aroused cunt.
"Hurry, Scotty, hurry, boy!" she cried out, no longer able to restrain her base desires. "Lick me! Lick my pussy!"
She knew that she no longer had to worry that Biff would stop the exciting action if he knew how much she wanted it, how much she was getting off on it. She knew that she had already given herself away and that her brother was turned on by how much she was enjoying what he and Scotty were doing to her.
With a little whimper, Scotty began lapping and licking his mistress' juicy pussy.
"Ohhhh, yesss," Gail moaned, closing her eyes in ecstasy.
Through her haze of desire and pleasure, she was only dimly aware that Biff was once again leaving the room.
For the next several minutes, she gave herself completely over to the exquisitely sweet torture of her dog's tongue licking her most sensitive pussy flesh. But her eyes flew open when she heard a strange clicking sound. To her surprise and excitement, her brother had returned and was now busily clicking picture after picture of the depraved scene with one of his many cameras.
"Good God, Biff!" Gail cried, but she smiled. She knew that her big brother had been a photography buff for years. He even had his own darkroom at home where he developed his pictures.
Gail had always been something of an exhibitionist. And she found that having a loaded camera trained on her turned her on even more than before.
"These'll be great," Biff murmured, still taking picture after picture.
Some of the photos would show Gail's lust-twisted face as her dog worked on her. Some would show close-ups of her pussy with Scotty's tongue buried inside it. Still others would reveal her jiggling tits with their fat, throbbing nipples.
"God, but I love this!" Gail cried.
Biff shot a roll of film and then put a fresh roll into the camera. He feverishly took picture after picture of the Irish terrier licking the girl's pussy.
Finally, Gail began to come. Her entire body shook and shuddered on top of the table as she came. Her pussy walls clutched at the dog's tongue, holding it in place during her orgasm.
Scotty whimpered as he felt his mistress' cunt muscles squeezing at his tongue.
Scotty's snout was coated with pussy juices which were mingled with slobbered dog-saliva. As she finished coming, Gail looked back over her shoulder and saw the dog's furry head wedged between her thighs, his tongue still working on her pussy.
But just then, Biff pulled the dog back.
"Enough for now, Scotty, you already made her come," the boy said.
The dog whined. His cock was hard and stiff. It jutted down between his furry hindquarters.
"Are you… are you going to make him fuck me now?" Gail asked hopefully.
"Soon," Biff said with a chuckle which let her know that he realized just how turned on she was.
He put the camera aside and picked up the vibrator again.
"Ohhh, Biff," Gail groaned weakly as she felt the humming vibrator fucking in and out of her pussy. Time and again, her brother brought her to the point of another orgasm, only to pull back and leave her suspended in a state of sexual frustration.
But as soon as she would simmer down again, Biff would once more shove the vibrator inside her pussy.
"God, you're driving me crazy!" Gail cried, tears filling her eyes.
Scotty watched the vibrator fucking in and out of the youngster's dripping pussy. He whined and barked, moving about impatiently as he waited for his turn to fuck his mistress.
Finally, Biff turned the vibrator off, just as his sister was about to come.
"You bastard!" Gail cried.
Biff laughed.
"Ready, Scotty?" the boy asked thickly. "Ready to fuck this little pussy?" Biff looked at the dog's cock and laughed again. "Yeah, I'd say you're ready! Looks like if I don't let you fuck this bitch right now, you'll come all over the table!"
"Yessss, let him fuck me! For God's sake, Scotty, fuck me now! I can't wait any longer!" Gail whimpered, wriggling her ass with anticipation.
CHAPTER THREE
"Go for it, boy! Fuck Gail!" Biff yelled, reaching for his camera again.
The Irish terrier yipped with excitement. He rose up on his hindlegs, planting his forepaws on Gail's naked back.
"Hurry, Scotty, fuck meeee!" Gail wailed, feeling her pussy quivering and burning.
Scotty humped his hindquarters against his mistress' back and ass.
"Yesss, God, yesss!" Gail cried as she felt the head of her pet's prick sinking into her wet pussy.
Her eyes went wide and she pushed back against him as he lurched forward, balancing on his hindlegs. The thick dog-cock spread Gail's pussylips open. The dog lunged forward again.
"Yes! Fuck me, you gorgeous doggy, you!" Gail screeched as she felt her pet fucking his thick prick inside her, jamming it to the hilt.
She felt her pussy walls stretched painfully, deliciously. Her pussy juices had lubricated her innermost pussy flesh but, even greased as she was, the teenager's tight little pussy gave the dog's prick an excitingly tight fit.
Scotty yipped. Then, he pulled his prick out of his mistress' pussy until only his cockhead was buried inside her.
"No, don't take it out!" Gail yelled in frustration. It had felt so good to have her little cunt completely stuffed with hard dog-cock. She longed to feel that thrilling sensation again.
"You sexy little dog-slut," Biff said, laughing at his sister's horniness.
The boy knelt there on the table next to the rutting girl and dog. He held his camera in one hand while, with his free hand, he stroked his aching cock.
"Shove it back into me, Scotty! Fuck your hard cock back into my pussy!" Gail cried desperately.
Scotty yelped. He threw his hindquarters forward with a brutal shove, burying his dog-prick to the balls inside his mistress' wet pussy.
"Yessss, that's it!" Gail groaned, relieved and delighted to once again feel her pussy so totally full of hard dog-cock.
"Damn! Gotta take some pictures of this," Biff muttered as he reluctantly released his cock and jumped down from the table.
He held his camera with both hands, aiming it carefully as he began to circle the table where the dog and girl were fucking each other eagerly.
As Gail and her dog fucked each other, Biff ran through a roll of film, and reloaded the camera with a fresh roll.
"Jeeesus, this is sooo good," Gail groaned. She loved the feel of her dog's throbbing cock fucking her so deeply. And she loved knowing that her brother was recording the lewd bestial fucking on film.
Scotty barked loudly as he continued to fuck his mistress from behind. He jabbed her several times in rapid-fire succession, his hindlegs quivering under the strain of his fast-paced fucking. Then, he would pause for a second or two and pull his cock almost all the way out of her cunt.
"Noooo!" Gail wailed each time.
