The very next afternoon, Dee and Kim both agreed that they would like to fuck the biggest dog they could find. As soon as they got out to the dog kennels behind their house, they excitedly checked all the cages to see just which dogs were boarded on that particular day.
"Randy!" Dee cried, spying the Great Dane. "He's still here and he's sure the biggest fucking dog around!"
"Great!" Kim answered, feeling her pussy beginning to drool with arousal. "Let's hurry up and do our chores. Then we can take Randy to the reception room in front and have some real fun!"
The Great Dane barked several times, and Dee and Kim exchanged lust-filled glances. They giggled when they saw the dog's cock was growing hard.
"Guess he can smell our turned-on pussies," Dee laughed as she and her twin sister hurried away to begin their chores.
The twins completed their chores in record time and eagerly led the horny Great Dane out to the large room.
He gave a high-pitched yelp and looked excitedly from one girl to the other.
"Wow! He's really getting a massive hard-on!" Dee squealed.
"Yeah, and I can hardly wait to taste it," Kim groaned as she and her sister quickly shed all their clothes.
Kim squatted down next to the standing dog, eagerly sucking his cock into her wet mouth. She ran her tongue over and around the still-hardening cockmeat. The dog threw his head back and howled, savoring the obscene thrill of the teen's mouth covering his prick.
"What a sight," Dee giggled as she nakedly got down on the floor before the dog. "Mmmmm, look at that nice, long tongue! I know how good it'll feel in my pussy!"
She spread her legs wide and dipped her fingers into her wet pussy, scooping up a large amount of thick fuck juice. Then, with a little groan, she raised her juice-smeared fingers to Randy's nostrils.
Whoof! Randy barked loudly as he smelled the girl's juice. Then he stuck his long, pink tongue out and roughly licked up the tasty juices, growling deep in his throat at the same time.
"Mmmmmfff," Kim groaned around the thickness of the dog-cock in her mouth. The dog was so excited by the combined thrill of having his cock sucked off and licking Dee's cuntjuice from her soaked fingers that his cock hardened and thickened more and more.
"Come on, you gorgeous dog! Give me your tongue! Lick my wet pussy!" Dee yelled as she reached up with both hands and gripped the sides of the dog's powerful head. She tugged at him, pulling him closer to her steaming crotch.
Randy flared his nostrils and got a good whiff of Dee's pussyjuice. That was all it took. The aroused dog plastered his hungry mouth tightly against Dee's pussy.
"Yessss, you crazy doggy! Lick me and make me come!" Dee screeched, her eyes on her sister's mouth which was still wrapped snugly around Randy's thick cock.
Kim moaned happily, sucking harder on the delicious dog-prick which throbbed lewdly against her inner cheeks. She reminded herself that this was a dog she was sucking off and that she was doing something most people would find disgusting. That thought thrilled her.
As Kim continued to give the Great Dane a skillful blowjob, she could hear the exciting sounds of the animal licking and sucking on her twin sister's little cunt. Kim's own pussy drooled out a steady stream of its juices, dribbling obscenely down her naked thighs.
The huge dog shot his tongue in and out of the teenager's cunthole, feeling Dee's strong cuntmuscles closing. Then he yanked his tongue out of her tiny opening and used it to whip her stiff clit.
"Ohhhh, yeah, that's fantastic!" Dee cried, tossing her head from side to side, still gazing at Kim's cock-stuffed mouth.
With both hands, Dee spread her pussylips wide apart so the pussy-licking dog could find her clit more easily.
"Oh, God, Randy!" Dee squealed, squirming with delight as she felt the rough surface of the flopping dog-tongue scraping across her exposed clit again and again.
Then, the Great Dane slid his tongue all over Dee's cuntlips and finally slid it back into her clenching cunthole.
"Yeeeooowww!" Dee cried as she felt the tip of the dog's tongue licking against her hot pussy.
Kim swallowed hard, taking more of the animal's pulsing prick into her mouth. She hollowed her cheeks inward and sucked as hard as she possibly could.
Randy growled with pleasure and Dee screamed and then laughed delightedly as the sound of the animal's growl reverberated throughout her pussy.
As Randy continued to lick Dee's wet pussy, lapping up all her flowing fuck juices, he humped his furry loins downward, fucking more of his prick into Kim's sucking face.
"Unnnghhh," Kim groaned as she felt the dog-cock sliding down her throat. She tightened her throatmuscles and sucked still harder.
Her tastebuds were fully aroused now, and large amounts of saliva filled the girl's mouth. She tasted several drops of pre-cum which dribbled off the end of Randy's dog-cock. And the pre-cum formed a lewd mixture with Kim's saliva, sliding down her throat into her belly. The dog-cock-sucking teenager knew that in just minutes, she would be happily swallowing a full load of dog-cum. She could hardly wait.
Dee watched her sister sucking the dog's cock, the lewd sight turning her on almost as much as the incredibly erotic thrill of the big, rough dog-tongue stroking her clit and fucking her tight little cunthole. She writhed all over the floor, her pussy drenched with juice now.
Both of the twins and the Great Dane were groaning and growling, and their eyes were glazed over with animalistic lust. The dog-tongue lashed Dee's clit harder. Kim deep-throated Randy's cock faster and harder.
All three of the lovers were panting hard now, their bodies shuddering with pleasure. The next time Randy shoved the full length of his tongue up Dee's cunthole, she twisted violently on its tip and came.
"Commmiinnng!" Dee screeched, tightening her pussymuscles hard around the reaming dog-tongue that had just given her such a delicious orgasm.
Seconds later, Randy's cum shot from his prick, flooding Kim's still-sucking mouth.
"Urrghhh," Kim groaned excitedly and her own orgasm rushed through her loins as she swallowed down every drop of Randy's tasty dog-cum. She moaned continually, still sucking on the dog-cock which twitched violently against the walls of her throat.
Randy finished coming, and he howled with pleasure, withdrawing his still-hard prick from Kim's cum-smeared mouth. The huge Great Dane stood there, his big cock throbbing between his furry legs. He looked from one teenager to the other.
When Dee's orgasm ended, she squealed with excitement and rushed over to Kim who was still coming. Dee pushed her twin sister down onto the floor so Kim was flat on her back. Then, Dee reached out and hornily stroked her sister's tits, pinching the stiff nips slightly.
"Oooh, Dee, I'm still coming!" Kim cried. "I know! And I'm just helping so you'll keep coming," Dee said with a grin. Her own little pussy was still pouring out a steady flow of juice which only thickened as she felt her twin's nipples pulsing against her pinching fingers.
Randy gazed at the twins with knowing eyes. Knowing that they were being watched by the Great Dane turned the teenaged twins on all the more.
"God, you always know just how to make my tits really hot," Kim groaned, writhing on the floor. Her sister's tit-caresses sent tingles through her stiff nips.
Suddenly, Kim sat up and faced her sister, her own hand reaching for Dee's tits. Looking directly into her sister's eyes, Kim began to stroke Dee's trembling tits. As the Great Dane watched the bitches, his cock hardening more, the twins stroked each other's tits.
Then, with excited grins, the girls fell into each other's arms and rolled about on the floor. Their naked bodies pressed together. Their budding tits flattened out against each other. Their nipples throbbed against one another. Best of all, their pussies smacked together, one girl's pussyjuice mingling with the other's.
"God, I need a fuck!" Dee cried.
"I think poor Randy does, too," Kim said with a husky laugh. "Get up on your hands and knees, Sis."
Dee obediently and eagerly got up on her hands and knees, her naked ass waving in the air in invitation.
"Great, now just stay there just like that," Kim said.
"Don't worry, I'm not going anywhere," Dee responded.
Kim led Randy over to where Dee was crouched on the floor, waiting to be fucked.
"Up here, boy!" Kim cried, patting her sister's back.
The horny animal got the message at once. He bounced up on Dee's naked back, all but knocking the girl flat on the floor.
"Ooof! This dog's huge!" Dee groaned. "I'd forgotten just how big he really was."
"Yeah, and so is his cock! Wait till you feel this hard-on in your cunt!" Kim said excitedly as she gripped the thick dog-cock and fed the prick inch by inch into her twin's gaping cunt.
"Oh, God, yeah! I can feel Randy's big cock inside me now! Ooooh, more! More dog-cock! I want it all!" Dee squealed.
The sight of her sister's little pussy gobbling up the Great Dane's big prick thrilled Kim no end. And the fact that she was actually stuffing the big prick into Dee's tight cunt just added to her arousal. Even as she saw Dee's pussy drooling out streams of juice, she felt her own cunt dripping with the same kind of liquid.
Randy barked several times, trembling all over as he felt his hard cock being guided into Dee's snapping pussy by Kim's clasping hand.
Kim stared down, moaning with excitement as she watched the long, thick dog-prick gradually disappearing up her sister's pussy until every bit of the hard meat was buried inside Dee.
"God, yessss," Dee hissed between clenched teeth. She felt her little pussyhole completely stuffed with the dog's prick. She could feel the big cock throbbing lewdly against the walls of her tight cunt and she shook all over, relishing the delicious sensation.
"Whew! He's all inside you now, Sis, that's for sure," Kim groaned, shaking her head and tensing all of her muscles in a desperate attempt to maintain control against the overwhelming tide of lust that rushed through every single fiber of her body.
"Yeah! Yeah! Fuck meeee," Dee wailed hornily.
"Suck my pussy, Sis!" Kim cried lustily as she suddenly threw herself down onto the floor in front of her sister's crouched body.
"Oh, God, Kim, your pussy looks soooo juicy!" Dee groaned as her sister spread her legs wide. Dee found herself gazing straight into her twin's wet cunt.
"Hurry, for God's sake, Dee! I'm so horny I can hardly stand it! Lick me! Eat my pussy! Make me come!" Kim squealed, pawing at her own tits.
Dee took one hand off the floor, struggling to maintain her precarious balance with one hand and both knees. It wasn't easy for the girl to keep her balance that way, for the Great Dane was still pounding her pussy with bone-jarring thrusts of his fat cock. And the impact of his savage fucking style caused Dee's body to shudder violently with each inward plunge.
With her free hand, Dee now ran her finger tips all over her sister's bloated pussymound.
"Ooooh, yes!" Kim cried huskily.
Dee felt her sister's juice smearing across her fingertips, and she swallowed hard, loving the lewd sensation. As Randy continued to fuck Dee dog-style, she stuck one finger between Kim's puffy cuntlips and stroked the girl's clit.
Dee lowered her head and stuck her tongue out. She ran her wet tongue all over her twin's cunt, lapping up the dribbling pussy-juice and feeling it trickling down her throat.
"Do it, Sis! Eat my pussy out while that dog's big cock fucks you raw!" Kim cried.
While Dee kept licking Kim's pussy, Kim reached out and grasped both of Dee's swinging tits. With one tit in each hand, Kim squeezed hard.
"Unngghhh!" Dee groaned, thrilling to the dual, excitement of her tits being squeezed and fondled by her twin sister, and her aching pussy being filled to the brim with dog-cock.
Dee suddenly thrust the full length of her wet tongue into Kim's cunthole.
"Aieeeee! Fuck me, Sis! Yeah, fuck me with your tongue!" Kim shrilled as she dug her fingertips savagely into Dee's tender tit-flesh. Then she moved her hands and wrapped her fingers around her sister's jutting nipples. She tightened her fingers around them, tugging them out from the rosy little circles which surrounded them. Then, she released the twin nips with a snapping sound and Dee groaned into Kim's cunt when she felt her nipples snapping back into place.
"Yessss! Keep fucking my cunt, Dee!" Kim yelled as she felt her twin's rasping tongue shooting up into her fuckhole again and again. Kim tightened her pussymuscles about her sister's tongue, and both of the teenagers groaned with excitement.
Randy pulled his prick out of Dee's snapping cunt until only its flared head was still inside her. Then, with a series of barks, the big Great Dane shoved fully back into her again. Once more, Dee's little pussy was filled to the brim with the dog's hard cockmeat.
Dee gurgled against her sister's wet pussy as she felt the dog impaling her pussy on his prick again and again. Each time Dee thrust her hips back to meet Randy's fat dog-cock, her tits slid in Kim's hands and Kim grasped still tighter, as if never wanting to release the tits.
Randy growled with pleasure each time he felt Dee's cuntmuscles tightening against his reaming prick. His balls were loaded with a fresh load of cum, and the animal sensed that it would be only a matter of seconds before he emptied his scum into Dee's hungry little pussy.
Dee shivered all over, loving all the lewd sensations that were bombarding her naked body.
Kim took her twin sister's nips between thumbs and forefingers and pinched hard.
"Aaarghhh!" Dee cried with pain and pleasure.
"Ohhh, yeah, I love it!" Kim cried, pinching Dee's nipples hard again.
"Yeeeooowww! Yessss," Dee hissed.
Randy barked as if he understood exactly what was happening. He pressed his furry underbelly even harder against Dee's back, pushing her downward as he fucked her with harder, deeper strokes.
Dee groaned with excitement. She was using both hands to brace herself against the floor again, and it was a good thing. For the dog was pushing against her so hard now that she had her work cut out for her to avoid being pushed completely down on her belly. If that happened, she would land right between her sister's legs. Not a bad place to land, Dee thought with a grin.
"God, yes!" Kim cried as Dee's tongue pulled out and began to whip at Kim's clit. "Lick my clit, Sis! Suck it! Bite it! Make me come!"
Dee wrapped her lips about the base of Kim's twitching clit and sucked with all of her might.
"Yes, that's it!" Kim gasped, tightening her hold on Dee's tits.
Dee sank her teeth into the edges of her sister's clit, and that was all it took to make Kim come.
"I'm coming, Sis! You did it! Yeah, you made me come with your mouth! Keep sucking my pussy while I come, Sis! Eat all my girl-cum! I love it when you do that!" Kim shouted, shuddering uncontrollably as she climaxed savagely.
Waves of orgasmic pleasure washed over the young girl and she clenched her fingers so hard about Dee's tits that little red welts rose up on the otherwise white titflesh. Gallons of cuntjuice flowed out of Kim's puckering cunthole as she came. Dee felt the thick juice gushing into her mouth and she moaned, swallowing it all down.
Long moments later, Kim's orgasm began to ebb. Dee raised her juice-smeared face. She grinned down at her ecstatic sister, panting hard.
"That was super, Sis," Dee groaned, thrusting back to meet Randy's prick, which was still skewering her little pussy.
"Yeah, it sure was! Now I want to suck on your tits," Kim said, sitting up again and holding both Dee's tits in her hands more gently. She tightly squeezed the two titmounds together, trying to form one big strawberry-topped tit.
"Do it, Kim! Suck my tits while Randy keeps fucking me! Suck them until I come!" Dee cried urgently.
Kim lifted her sister's tits up and out. She lowered her face toward them. Kim greedily sucked them into her mouth.
"Yessss," Dee hissed.
Kim was sucking and licking Dee's nipples, feeling them throb lewdly against her lips and tongue. She was sucking as much of the surrounding titflesh as possible into her wet mouth as well, until her little mouth was stuffed to overflowing with the firm tit-flesh.
"Oohhhh, aaarghh, unnhhh," Dee groaned, throwing her head from side to side as her sister tongued and sucked her tits.
Dee continued to shove her hips forward and back. She watched Kim suck her tits as her own pussymuscles clamped tight and then released the fat dog-cock inside her.
Kim sucked harder on the other girl's nipples. Then Kim bit none too gently on the strawberry buds.
"Yieeeee!" Dee cried as jolts of pain and pleasure shot through her entire body.
Randy barked again as he pulled his prick almost all the way out of the teenager's pussy. With a savage growl from deep in his throat, he fucked back in, harder than ever.
At that precise moment, Kim again sank her teeth into Dee's nips. The combined sensations took Dee over the edge.
"Awwww, shijit, commmiiinnnggg," Dee panted hoarsely.
The Great Dane felt a great outpouring of cuntjuice completely soaking his prick as the teenager came.
Knowing that Dee was coming thrilled Kim to the max. She tugged Dee's nips between her teeth and shook her head from side to side in a violent series of movements, as if she were a dog.
"Yessss, commmiiinnnggg!" Dee cried, throwing her head back and feeling herself flush from head to toe.
Dee shoved her hips back as hard as she could. Randy thrust forward to meet her, and his balls finally exploded, showering the teenager's pussywalls with hot dog-cum.
