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.
