"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.
CHAPTER NINE
It rained steadily for a week after that, reducing the dog pen behind the kennels to a muddy swamp. The fence-enclosed dog pen was bare of grass. And, after the hard-pounding rain, it looked more like a huge pig sty than anything else.
Saturday morning, the Dixons received an urgent telephone call. The twins' aunt, their mother's sister, had taken a bad fall and broken her hip. She was all alone and needed help badly. After some hurried instructions to the twins about the kennels and a few loving words about being sure to take care of themselves, the twins' parents left town.
After waving their parents off, Dee and Kim went out to the kennels. It was always their favorite place to be and now they could stay out there just as long as they wanted without arousing their parents' suspicion.
After completing their chores, they stood facing each other, their feverish thoughts running in the same exciting direction.
"I'm hornier than hell," Dee said with a little giggle.
"Me too!" Kim responded, her eyes widening.
"Let's let all the dogs out into the pen in back," Dee said eagerly.
"But it's a swamp out there… all muddy it's a mess," Kim said, wondering what her sister had in mind.
"So what?" Dee asked, beginning to run her hands over her own tits and moaning softly.
Kim's eyes widened more as she watched her sister. She licked her lips, feeling her little pussy beginning to drool.
"Well… the dogs will get filthy and we'll have to wash them all off afterwards," Kim said weakly.
"So what?" Dee said again with a casual shrug of her shoulders. "Just think of all the fun we can have with the dogs out in the mud. As for washing them afterwards, remember that we'll have to wash every single part of their bodies!"
"Yeah, that's right! Even their cocks!" Kim cried, catching on.
"Especially their cocks," Dee said and they both laughed as they ran to release the dogs.
"Too bad Randy went home a few days ago," Kim muttered as the girls opened the dogs' cages and shooed the animals out into the large muddy pen behind the kennel building. The bitches boarding there whined in disappointment, but that was too bad.
"Yeah, he was one great fuck all right," Dee agreed. "But we've still got Dancer and Leroy and a few other dogs here we haven't ever made it with before!"
