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!"
"What a gorgeous Collie dog," Kim murmured as she and her twin stood at the entrance to the dog pen, watching all the dogs excitedly cavorting in the mud. "What's his name?"
"Would you believe Laddie?" Dee asked with a grin.
"You're kidding! How original!" Kim said, laughing.
"Yeah, I know. But I agree that he's gorgeous. And look at that big Bulldog over there. He's got a hard-on that's making my mouth water," Dee said, her little pussy growing hot beneath her shorts.
"Me too! His name's Baxter. I read his nametag when we let him out," Kim said. "Come on, we're wasting time! Let's strip!"
Within seconds, the horny twin sisters were completely naked and they laughed with delight when they saw the dogs looking at them with real interest.
"You know, I feel kinda sorry for those three female dogs inside," Kim said, glancing back at the kennel building. "Can't we let them out here too?"
"No, Sis, if we do that, we'll have too much competition. These horny males might want to fuck them instead. And you know how strict Daddy always is about separating the two sexes. The owners don't want to find out later that their bitch dog is pregnant by some stud dog they don't even know," Dee said.
"Yeah, that's right. But I feel sorry for them. They'd probably like to be out here too," Kim said.
"Don't worry, Sis. After we have our fun with these big-cocked dogs, we'll clean them up and put them back in their cages. Then we'll let the bitches out for awhile so they'll have their turn too," Dee said.
"Okay!" Kim said, feeling better about the whole thing and the twins grinned at each other.
Dee stepped into the dog pen. As she stepped into the oozing mud, she groaned, feeling the muck go all the way up to her ankles. She joined the dogs, stroking them, playing with them, while Kim watched from the sidelines.
"Go on, Sis!" Kim urged, turning on more as she watched her sister with the dogs who were all sporting big hard-ons now. "Don't be afraid to get dirty!"
"You should talk," Dee laughed. "You're too chicken to even come out here!"
"I'll show you!" Kim said, laughing too as she wallowed out into the muddy dog pen and moved to her twin sister's side.
Dee cupped her own tits. Cooing with pleasure, she rubbed them, plumping them up.
"Do you like my tits, Sis?" she asked thickly.
"Sure, you know I do," Kim rasped hoarsely. "They're gorgeous."
"Mmmmm, my nipples are aching. They're so stiff," Dee said. She pressed the pads of her thumbs against the throbbing points of her nips, pressing and rubbing them.
Forming a circle around the two girls, the dogs barked excitedly, all of the horny stud animals watching the girls' every move.
"God, Sis, you're making my pussy so wet and hot!" Kim groaned.
"That's why the dogs are getting so turned on. They can smell our pussies. You know how that always gets to them," Dee said.
"Play with your pussy, Dee!" Kim cried. "Get it good and hot for the dogs! Make more fuck juice so the dogs can smell it!"
Dee stood there in the mud, pinching her stiff nipples, tugging at them. Her other hand drifted down her tummy and fell on her damp crotch. She stroked her juicy cuntlips. They rippled lewdly under her massaging fingers. She continued to tug and pinch her nipples with one hand while she fondled her cunt with the other.
"Wow! You're really horny! I can see a whole bunch of juice coming out of your pussy!" Kim cried excitedly as she watched her sister with lust-glazed eyes. "And the dogs can smell it too! Listen to them!"
Kim was right. The dogs all crowded closer to the twins, pressing their furry bodies against the girls and whining and whimpering with doggy lust.
Wetness oozed in Dee's pussy-slit, smearing on her stroking fingers. She began to rub her cunt up and down as fast and hard as she possibly could.
She spread her legs wider, pressed her middle finger to her sticky cuntlips, and slid it on inside her. The young girl threw her head back and moaned. She stood there in the mud and finger-fucked herself, her legs bent at the knees, her stiff-nippled tits jutting straight out.
Faster and harder she pumped her finger in and out of her cunthole while the horny dogs moved still closer, all of them sniffing at her aroused cunt.
"That's enough, Sis," Kim groaned, her own little pussy dripping with juice. She moaned as she felt a cold wet nose burrowing against her aching cunt.
"Just a little more," Dee panted, reluctant to stop fucking her finger in and out of her wet cunt.
"Stop, Sis! Save some for the dogs!" Kim said urgently.
"Yeah, I guess you're right," Dee giggled as she withdrew her juice-soaked finger from her pussy. "Who wants it?"
Dee held her finger out and felt three dog-tongues licking it hard.
"Wow, Sis, you're really acting like a bitch in heat," Kim said, shaking her head in awe.
"You think so? Then watch this!" Dee said teasingly as she suddenly dropped to her hands and knees in the mud.
"What the fuck are you doing?" Kim cried. Dee began to move around the dogs on her hands and knees. Her tits and ass jiggled temptingly and although the animals appeared to be a little confused by the girl's behavior, they were also very turned on. It was as if the girl had become one of them and their cocks grew fatter and harder as they watched her.
"God!" Kim cried, beginning to stoke her own pussy as she watched.
Dee padded up to her sister and brushed her naked flesh against Kim. Then she stuck out her tongue and licked the girl's free hand. With her other hand, Kim was still stroking her own pussy, running one finger in and out of her aching fuckhole. With her free hand, Kim pat ted the top of Dee's head.
"Good doggy," Kim said with a husky laugh. Suddenly, Kim took her hand from her pussy and used both hands to give her sister a powerful push downward. Dee fell into the mud and laughed. Dee gasped as she felt trickles of the slimy mud oozing into her cunt.
"Wow! I like that!" Dee panted.
Dee's white back, ass, and legs, stood out against the dark, engulfing mud. Dee shivered with perverse pleasure as she felt the thick mud coating her tits. The stuff rubbed against her stiff nipples and Dee moaned with excitement.
Dee struggled to her hands and knees again, mud oozing over the front of her body. She crawled around, laughing excitedly, the dogs an following her. She wallowed in the mud, the front part of her lovely young body now covered with a thick coating of the dripping mud.
"You horny bitch!" Kim cried, delighting in the lewd sight of her twin sister gleefully rolling about in the mud.
Laddie, the gorgeous Collie dog, moved to the front of the pack, whining as his sensitive nostrils caught the arousing scent of a bitch in heat.
The Collie pressed his body against Dee's. He pressed his snout against the teenager's mud-spattered tits, sniffing and licking. Then he circled her body, his nose prodding into her ass and cunt.
"Oh, yeah, Laddie, go for it!" Dee cried, wiggling her tits and ass to and fro.
The Collie barked as he mounted Dee. His muddy forepaws slid across her back. He humped his underside against Dee's ass.
"Yeah, fuck her good, Laddie!" Kim cried, leaning against the fence as she moved both hands to her cunt. She thrust the middle finger of one hand up into her puckering cunthole, fucking it in and out while she watched her sister and the come. With the thumb of her other hand, she rubbed her clit. She sank the middle finger of that same hand into her asshole, bucking back and forth between both hands.
"Yessss, Laddie, fuck meeee," Dee wailed, jerking her head up. She reached behind her body and guided the dog-cock into her cunt. She pressed the fat prick to her cuntlips and worked it inside her, using a screwing motion, jamming it deep inside her.
The fat dog-cock of the come was fully inside Dee's pussy now, filling her, stretching her pussywalls out.
"Yesssss! That's it! Now fuck me!" Dee gasped.
Laddie yelped excitedly. Kim groaned. The other dogs all whined as they sat down in the mud, as if realizing that they would just have to wait for their turn.
Laddie pushed forward deeper, driving his cock into Dee's pussy with hard stabbing thrusts. Dee felt the tip of the dog-prick striking the back wall of her pussy and she cried out with animalistic pleasure.
Suddenly, Dancer, the Irish Setter, detached himself from the other dogs and he moved over to Kim, rubbing against her legs. Kim squatted down and took one hand away from her pussy and asshole. With that hand, she began to jerk off Dancer's enormous hard-on.
Dancer's cock throbbed in Kim's grasp. The young girl tightened her fist around the pulsing prick and jerked it up and down. At the same time, Kim continued to pump her finger in and out of her pussyhole with her other hand. All the while, both Kim and Dancer kept their eyes riveted on the thrilling action taking place just yards from them. They were hurriedly gazing at Dee and the Collie fucking each other.
Laddie was fucking his cock into Dee hard and fast now, fucking them both toward orgasm.
"Yeah! I'm gonna come in a minute, Laddie! Fuck me haaard!" Dee cried, licking her lips as she looked at the other dogs, her gaze moving from one hard cock to another.
Dee leaned forward more, bracing her forearms against the muddy ground to brace her body against the come dog's hard-driving fucking. Each stroke of his huge prick threatened to knock her forward.
Suddenly, Laddie fucked deep inside Dee's pussy, and he came. He tilted his furry head back and howled up at the sky as he unloaded. The other dogs barked and howled along with him.
"Yessss! Commmiiinnnggg!" Dee screamed as she felt the Collie's cum gushing into her cunt and she came with him.
"Wow!" Kim gasped as her own orgasm pounded through her.
Dancer yelped and released a thick stream of dog-cum into Kim's pumping hand. Kim raised her sticky hand to her face and licked up the tasty jism, moaning with pleasure.
Satisfied now, Laddie dismounted from Dee, popping his dog-cock out of her still-spasming cunt.
The instant that the Collie trotted away, the big Bulldog, Baxter, leaped up onto Dee's back.
But this time, Dee felt the fat dog-cock nudging against the crack between her asscheeks.
"God, Kim, he wants to bugger my ass!" Dee squealed.
"All right!" Kim cried excitedly. She and Dancer were both breathing hard from the force of their big orgasms.
Dee reached behind with both hands and eagerly spread her asscheeks wide.
Baxter pushed forward and fucked his huge cock into the girl's tiny asshole.
"God, that hurts! But it feels great!" Dee cried, tears of joy and pleasure streaming down her face.
The Bulldog wrapped his forepaws around the girl's chest, squeezing her firm tits with his paws, almost using them as handles as he fucked Dee.
"Oooooof!" Dee gasped as the dog's hard cock-thrusts knocked all the air out of her.
When Dee caught her breath, she immediately began to respond to the Bulldog's ass-fucking movements. She writhed and thrust back at him as he fucked into her again and again. He gripped her tits tightly with both paws, clasping both of the budding mounds.
"Unnghhh, good, really, really good," Dee grunted as she strained to tighten her assmuscles around the animal's cock, squeezing it lewdly inside her bunghole.
She felt her sharp claws of the dog digging into her nipples.
"Owwwww!" Dee yelled, but she grinned with delight.
The Bulldog barked and withdrew his hard prick until only its tip remained inside the teen's clenching ass-ring.
"Nooooo! Stick it back in meeee! Don't tease meeeee," Dee wailed.
Kim giggled, thinking that her silly sister was acting as if her lover were a man instead of a dog. But, then, who was she to talk about acting silly.
Baxter the Bulldog reared back and lunged forward, sending the entire length of his long, thick prick up Dee's aching, distended asshole.
"Yesssss, that's a good doggy!" Dee panted. "That's it! I can feel your fat dog-cock all the way up my ass! Ohhhh, God, it's so big and thick and hard! And I can even feel it throbbing! God, what a turn-on! Fuck me, doggy!"
Dee continued to match the animal thrust for thrust, fucking back at him with her hips and asseheeks. Then she reached between her legs and gently gripped his swinging balls.
Baxter howled as he felt the girl's hand closing around his cum-laden balls. He began to fuck her ass harder and faster now, sensing that his orgasm was not far off.
"Mmm, I can feel your cum inside your balls, Baxter! It feels all hot and thick," Dee moaned.
Baxter barked as he fucked the full length of his prick inside her ass and held there for his orgasm.
"He's gonna come! I can tell! Yeah, come hard, Baxter! I need your cum sooo bad! Come, doggy! Come inside my ass!" Dee cried as her own orgasm began.
Baxter barked continually as he unloaded.
"Yesssss!" Dee shrieked when she felt the dog's hot cum gushing into her ravaged asshole. Dee came hard, right along with him. As her orgasm pounded through her body, she savored the feel of the Bulldog's jism spilling out of her tiny asshole and running lewdly down her legs and on into the mud.
Then Dee slumped forward, feeling spent.
"I gotta rest," Dee panted.
"Okay, then you can watch while I get it on with one of these doggies," Kim said eagerly, moving away from the fence and looking around at the dogs, trying to decide which cock she would like to feel inside her.
Dee turned around and sat down in the mud, moaning as she felt the gooey stuff oozing into her ass-crack. As Dee settled down into the muddy ground, a couple of the dogs moved to her side. One of them began to run his long, rough tongue all over her face and neck and shoulders. And the other dog licked her tits.
Leroy, the beagle, moved toward Kim with an eager expression on his furry face, and Kim laughed.
"Okay, Leroy, you've got a hard-on there that could break a plate so I guess you're the one," Kim said. She lay on her back in the mud not far from her sister. Kim spread her legs wide, wondering if Leroy would mind getting his cock all muddy when he fucked into her pussy. Kim's little cunt was running thickly with the dirty substance.
Leroy straddled the teenager's body with his own, his head right above hers.
"Mmmmm," Kim murmured as she felt the dog's furry chest pressing down against her own, squashing her tits. She began to run her hands all over his body, thrilling to the way the beagle's hard muscles rippled beneath her bestial touch.
"Fuck her, Leroy!" Dee yelled excitedly from where she sat with the two dogs licking her face and tits.
"Yessss, fuck meeeee," Kim hissed between clenched teeth.
