Scotty gave a little yelp as he ran over to the table in the middle of the room. He stood there, gazing up at his naked mistress, his long, pink tongue lolling out of one side of his mouth. Dog-drool dribbled off the end of it. He panted. His body was tensed. He looked as if he were barely able to restrain himself, but he seemed to sense that Biff was the one in charge here and that he had best not move until he received his next command.
"Ready for Scotty now, Sis?" Biff asked hoarsely.
"No!" Gail protested, thinking that no matter how much her little pussy was throbbing with desire for her dog's cock, she had better put on an act for her brother's sake.
"Oh, really? Hell, Sis, you're in no position to argue with me!" Biff growled as he gripped one of her tits. He worked the mound of tit flesh out to the side and pinched the nipple until Gail cried out.
"Now are you going to do as I say?" Biff demanded, not realizing that his little sister's cry was one of excitement as much as of pain.
Gail nodded dumbly, saliva spilling out of her mouth around the rubber bone.
"That's better," Biff laughed. "I thought you'd see things my way."
Scotty whined eagerly, expectantly as he watched the humans' actions. He could smell the scent of sex in the air, and he could smell the aromatic juices dribbling from his mistress' pussy.
"Hungry, Scotty?" Biff asked with another laugh.
Scotty barked.
"Okay, you two stay right here. I'll be right back," Biff said, striding quickly from the room.
While her brother was gone, Gail remained obediently in place across the top of the big circular table. She could hear her dog's harsh panting. And she could feel her little cunt burning and itching with desire.
"Don't worry, Scotty," she whispered, "I don't know just what Biff's got in mind, but let's just play along with him… 'cause I've got a feeling that it's gonna be good!"
Just then, Biff returned with an opened can of dog food. Smelling it, Scotty let out another bark of excitement.
Biff chuckled. He stood behind his sister with a tablespoon and the opened can of dog food. He spooned out a large portion of the dog food and smeared it on Gail's pussy and ass crack. He smeared more of it on her inner thighs. The thick stuff clung to her pussylips and little pieces of the food fell off, spattering on the carpeted floor.
"How's this feel, Sis? Bet you love it!" Biff said nastily. He parted his sister's cuntlips and spooned some of the dog food inside her pussy.
Gail trembled on the table as she felt the dog food being smeared all over her pussy and thighs and ass. She thought her brother had to be just about the grossest person she had ever known. But she also thought that what he was doing to her was exciting. As if to prove that point, her pussy dribbled out more juice.
Scotty's entire body shivered with anticipation. He didn't know which turned him on more… the smell of the tempting dog food, or the sexy scent of his mistress' pussy juices.
"Up here, boy!" Biff commanded.
Scotty immediately leaped up onto the table.
Biff chuckled as he guided the animal to his sister's ass and spread thighs.
"God, Biff!" Gail cried, as if fully realizing for the first time what her brother had in mind.
"Yeah, boy, c'mon," Biff urged the dog, which really needed no urging at all. "There's plenty of good stuff here for you to eat."
The Irish terrier's jaw gaped open. Hot humid doggy-breath poured from it, washing over Gail's belt-whipped ass flesh. Scotty unfurled his pink tongue which dripped with saliva. Huffing and puffing, his furry sides quaking with his excited panting, the dog nuzzled his snout between his mistress' legs.
"Ohhh, Scotty!" Gail whimpered as a wave of fresh animalistic desire swept through her body.
Her little ass squirmed first this way, then that, as it was eagerly nuzzled by the snout of the horny dog. When Gail felt Scotty's tongue lapping up and down her ass crack, then over her pussylips, she let out a hysterical screech.
"Shiiiiit!" she hollered.
"I knew it!" Biff chuckled. "You love having that dog's nose up your ass and pussy!"
Scotty gulped down the dog food, his tongue a blur of pink motion as it rolled up and down Gail's ass crack, and over her trembling pussy-lips.
The young girl was half out of her mind with bestial desire by now. Her body writhed and wriggled mindlessly and a series of low guttural groans came from her mouth. The rubber bone had dropped out of her mouth by now, and Biff made no move to stuff it back in. The boy was far too busy rubbing his prick and watching his sister's ass and pussy being licked by the dog to worry about the toy-bone.
When Scotty had licked all of the dog food off his mistress' ass, and most of it off her pussy, he moved his tongue down between her legs, to lick her cunt directly.
"Jesus God!" Gail screamed, overwhelmed by the icy-hot tremors of pleasure which rushed through her.
Scotty could taste the girl's pussy juices, which mingled with the dog food, and he gulped down the exciting mixture eagerly. Little growls of doggy pleasure rolled out from deep in his throat. Hearing them, Gail grew still more aroused.
"I'll be a son of a bitch!" Biff muttered, shaking his head from side to side.
Still watching the dog licking the dog food off Gail's cunt, Biff unzipped his fly and hauled his stiff prick out. He began to jerk himself off.
Gail loved the feel of her pet's rough tongue scraping over her sensitive pussylips. The knowledge that her randy brother was watching it all only served to excite her more.
The hungry dog was very thorough in his lickings. Where he licked his mistress, he licked her clean. In a matter of minutes, the young girl's ass, upper thighs, and pussylips were glistening cleanly.
"Get in there, boy! Get in that little pussy! You've got a lot more dog food to lick out of her!" Biff demanded, his fist a blur as it raced up and down the full length of his bursting hard-on.
"Yessss, Scotty, listen to him! Lick inside my pussy!" Gail cried, knowing that she was about to come.
Scotty rammed his tongue between the girl's puffy pussylips and lapped at her hard. His tongue spread the bloated cuntlips wide open. He licked all the hardest-to-reach particles of food from inside her juicy pussy.
"Commmiiinnng!" Gail cried just then.
"You lousy little dog-whore!" Biff thundered as his own orgasm began.
He moved around in front of Gail and shoved his orgasming cock into her wide-open mouth. The young girl's lips reached out hungrily for the cum-spilling cock.
"Ummmfff, unnnghhh, goooooood!" Gail gurgled.
She sucked on her big brother's shooting cock while Scotty continued to lick the deepest reaches of her pussy with his horny tongue.
Gail eagerly swallowed her brother's cum for the second time that day. At the same time, Scotty drank down her flowing pussy juices.
Biff pulled his drained prick from his sister's mouth and left the room before the dazed girl could ask him where he was going.
"God, Scotty," she murmured thickly, "isn't he ever going to let you and me fuck?"
Scotty barked twice, and when Gail turned to look at him over her right shoulder, she saw that the dog's cock was jutting fully out from its furry sheath, rock-hard and clearly ready to fuck.
Before Gail knew it, her brother was back. He stood in front of her, showing her what he held in one hand.
"My God!" Gail cried, staring at the eight-inch long vibrator. "Where'd you get that thing?"
"It's just a little something I like to use on my girlfriends now and then," Biff said, enjoying the shocked expression on his sister's face. "Thought I'd let Scotty here watch me using this thing on you… that should turn him on even more!"
"Jesus, Biff!" Gail gasped. She was disappointed that her brother still was not ready to let her dog fuck her. But she knew that she would really get off on the feel of the big, hard vibrator up her aching pussy.
Biff flicked a switch, turning on the vibrator. He climbed up on the table, going down on one knee behind his sister's ass. Gail squirmed as she felt her little pussy being poked and prodded by the huge head of the humming vibrator.
Biff laid the length of the vibrator along her trembling pussylips.
Scotty moved forward, his cold, wet nose nuzzling against his mistress' ass.
"Good boy!" Biff said. "You love the smell of her wet pussy, huh? Well, don't worry, Scotty, we're gonna get it a lot wetter for you!"
Using the head of the vibrator, Biff pried Gail's pussylips wide open. He pressed the throbbing vibrator against the sleek pink pussy-meat inside, which quivered in response.
Scotty's nostrils flared as the thick scent of his mistress' aroused pussy tingled in his nose. He watched with lust-glazed eyes as Biff continued to fuck the vibrator deeper into the girl's cunt.
The humming tool coaxed thick juices from Gail's pussy membranes. The pussy sauce lewdly coated the vibrator, lubricating it.
"Ohhh, God, what you're doing to me… it feels soooo good… don't stop," Gail purred, shoving her hips back to meet the next inward rush of the substitute cock.
"Don't worry, bitch, I'm not about to stop… not yet!" Biff said with a husky chuckle.
Back and forth he worked the vibrator, fucking it in and out of his little sister's tightly clutching cunt. Her pussy muscles tugged at the invading vibrator, sucking it deeper inside her. Gail shook and moaned with pleasure. She felt as if she had fallen in love with the hard vibrator. It was making her feel so good, so intensely good, she could hardly stand it. Yet, there was no way in the world she could pull away from it.
Beads of sweat shone on her face. Her eyes were unfocused and they began to roll. Her tits jiggled and her nips grew so stiff she was sure they would explode any second. She spread her thighs wider still, as if silently urging the vibrator to penetrate her even deeper. The thick tool fucked farther into her cunt, her juices easing its penetration.
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.
