Ace growled as his leg muscles tensed up and the ones on his arms bulged, muttering curses through clenched teeth but not loud enough for his son to hear them from behind the steering wheel. Junior was way too young to drive, of course, but old enough to keep the wheel turned to the right while he pushed their car off the road. The damn thing had been checked up two month’s ago and it had decided to die on them in the middle of nowhere at night!
And to make matters worse it was pretty heavily loaded down, with supplies and gear to last the two of them for a week in the great outdoors. It also had insect repellant which Ace was tempted to dig out, since the Rottweiler’s short fur was little defense against the big hungry mosquitoes swarming around this unexpected buffet.
“Okay Junior, that should to it…” he said, straightening and dusting off his hands before swatting in irritation at the insistent bloodsuckers. “Let’s see… well I got a signal. That oughta be enough to get a tow truck out here. No internet service though. How’s yours?” he asked the twelve year old as he closed the car door and began flailing his arms at the swarming mosquitoes.
“Same. Why do we need it though? I thought we came here to ‘unplug’?”
“Not quite here son. The camp-site is still about twenty miles ahead of us, and if you were my size we’d still have a hard time hauling all our gear on foot. I wanted to see if there was a place out here we could spend the night.” He said, trying to remember how they used to find this sort of thing out before they had GPS and an interactive map in every pocket.
“If… if it helps I saw a hotel sign about two minutes back…”
“Well looks like it’s our best shot. Here, grab your backpack and just leave the rest. Don’t worry son, I’ll straighten this out by morning and tomorrow we’ll be on our way…” Ace said.
*******
Ace had no idea why someone would name their hotel “The Switchboard” but he suspected they were still in use the last time this place was renovated. But beggars couldn’t be choosers and after walking through a bug-infested night they were ready to settle for anything. The thin and ferret standing at reception with a shirt and a bow-tie looked shocked to see them, but Ace figured that they must have looked like hell staggering in at this late hour.
“Yeah. No I don’t know exactly where we stopped. It’s off the side of the road… Look, I pay extra for all that tracking junk, if I give you my info can’t you just find the damn thing?” he said to his phone, trying to keep his calm while at the same time doing whatever it took to get them the room. They had vacancies so he’d just handed his credit card to the receptionist and figured that would be it, but the ferret was trying to push some papers towards him.
“Wha… no the battery’s still fine. Everything has juice – the dash lights up, the radio, the headlights, but that’s no good to me when the damn engine won’t turn over, is it!? So that goddamned GPS is still beeping away, just waiting for you to find the damned thing…” he said, skimming the paper until he got to what sounded like the usual liability crap. After that he just scrawled his signature, since he wasn’t here to sue this place for whatever it was worth. He was an honest man who worked with his hands for a living, out here to spend his vacation with his boy, not to fucking litigate! The ferret looked like he was about to say something, but one glance at the irate Rottweiler made him change his mind. The key he handed him was an actual key and had a strange scribble instead of a number, but the place was small enough that Ace figured he’d manage to find it. At this point, he was sure everything that could go wrong today already has…
*******
“Welcome to the Switchboard. You… I’ve seen you before, haven’t I?” the receptionist said. He wasn’t the best at putting names to faces, and in this place it was especially tricky. The ones currently in front of the desk were both in their middle years, a short tabby tomcat and a goat who stood a little over six feet.
“Yeah, we’ve been here before, but this time is a bit special. We just got married and we decided on this place for a sort of honeymoon.” The feline said.
“Oh, well congratulations! We don’t have a honeymoon suite, of course. Wouldn’t make much sense in this place…” he said.
“Yeah, guess it wouldn’t.”
“Right, so let me just get the paperwork out of the way…” he said, handing each of the men several sheets of dense print.
The two skimmed it but if they’d been here they were familiar with the unique way in which the Switchboard Hotel operated. He was a bit worried about those two newcomers. The boy had seemed a tad young for this place, but then again he had the required signatures. The newlyweds each signed their copies and after filing them away the ferret handed them a key with their suite’s symbol before wishing them a pleasant stay. With the last vacancy filled and a nice even number of occupied rooms, the receptionist locked the doors and prepared to make the switch.
*******
“This is always so exciting. Y’know – wondering who we’ll get…” Billy said, sitting on the bed with his ankles crossed.
“Yeah, shouldn’t be long now. I swear I can’t figure out how they do it – some sort of mad science or hocus pocus and they just switch your body with someone in another room. And then it’s no holes barred until dawn…” Tom said, sitting next to his new mate.
He’d met Billy online and they’d mostly just role-played a ton of kinky fantasies at first, but eventually they met in person and hit it off. And at some point they’d found out about this weird little secret – a hotel where you can trade bodies with strangers for the night. It seemed like a perfect place for a couple of kinky guys like the two of them to spend a honeymoon.
“I’m up for anything, as always, but I hope you wind up having the cock tonight. Topping was fun that one time, but you’re just so much better at it…” Billy said.
“Don’t worry – whatever I get I’m gonna wind up giving to you…”
*******
To this day Terrence wasn’t sure how it actually worked, but he did everything as he was taught by the previous manager and the thing always went off without a hitch. With a practiced hand the ferret shuffled the thin deck of dog-eared cards before flipping them over one by one, two cards per row until they were all resting on the little table behind the reception desk. The backs looked like playing cards, but the face of each one had a symbol – the same ones used to label the rooms, and each pair would be trading places any second now. As far as Terrance was concerned, his part in this was done. The guests would have their fun and early in the morning he’d come back here and shuffle them back, putting everyone back in the body they’d checked in with…
*******
“Whoa, here we go…” Tom said in a deep, gravely tone as the sharp, sudden vertigo began to clear. 
He’d been here before and even though he had no idea how it was done he knew what happened at the Switchboard. His paws shot out to steady himself, landing on the soft bedding covering a firm mattress. A lucky break, since being flung into a new body was a tricky thing if the original owner had been standing a moment ago. The room stopped spinning as abruptly as it had started, and as always it wasn’t the same room. He forced his eyes to focus, impatient as always to see who he would be for the night.
“Holly… jackpot!” he said,  in a deep, masculine rumble as he examined the strong arms propping him up on the bed, the short black and orange fur doing nothing to hide the bulging muscles on his limbs. 
And since he was wearing nothing but a sleeveless shirt and a pair of boxers there was a lot of sleek fur showing. Fuck, either a Dobie or… yeah, a Rottweiler! He thought to himself as he touched his new face, finding a short and blocky muzzle instead of the long maw of a Doberman. Once he was sure he could stand up straight he slipped out of bed and examined himself in the floor-length mirror. A toothy white grin spread across the masculine mug of the big dog he’d been switched with as Tom realized just how tall he was standing.
“Aww yeah, and built to breed!” he growled lustily as he cupped the bulge his boxers couldn’t hide. He wasn't sure what Billy would turn out to be for the night, but this was a hell of a body to wear for their honeymoon.
“Ohmygosh!” came the cry from the adjoining bathroom, high enough for Tom to wonder if he’d be consummating his marriage with his new wife instead of his new husband. Not that he minded. You didn’t come to this place if you weren’t adventurous, and if it turned out Billy did have a pussy he had just what it needed. 
“What? What do you look like?” he asked.
“I… I can’t quite see…” came the same slightly high-pitched voice.
“You… you’re someone blind?”
“No, the mirror’s too high up!”
“Wha…?” Tom asked, but stopped dead when his new life mate stepped out. “Holly hell! How… are you…” he said, or rather stuttered as the diminutive figure made a dash for the mirror.
“Oh my… gosh! Will you look at me! Ooooh, I look soooo cute! I must be… what, twelve or something?” asked the little Rottweiler with his tail whipping above his pajama-clad bottom. He was still holding his toothbrush and had a fleck of toothpaste on the right of his grinning mouth, making him look like the cutest little rabid dog in the world. “Oh my God and look at you!”
“Yeah, look at me… see a resemblance?” Tom said, still trying to imagine if the reflection in the mirror could be anything other than a father and son. “God damn! I mean this is a place for kinky folks like us, and I sure as hell don’t mean to judge but… who’d bring along their tween son to the switchboard?”
“Come on, don’t get al prudish on me now… ohmygosh, look at how cute my tush is!” Billy said, gushing happily as he examined the admittedly adorable puppy body he was in. “Anyway, it’s not like they are really doing anything together. Like, really together. They just become two different people and then they get back to being father and son. Maybe that just works for them…”
“I guess. And fuck, this just works out great for us!” Tom said, his moral quandaries eroding as Billy posed in front of the mirror.
“I know, right? All those steamy, late-night role-play sessions and now you get to finally be my daddy!” the black-and-orange puppy gushed, pressing himself up against the big dog and standing on tip toes as he angled his muzzle up. As he leaned down to kiss his ‘son’ Tom felt the young body warm against his own and felt his inhibitions crumble. After all, it wasn’t like he was really doing it with a kid. Despite appearances they were both consenting adults, even though he knew from experience that Billy could play the hell out of a cute young boy eager for his daddy’s cock.
And when it came to dad-bodies, this one was a gad-damned Cadillac! Tall and in its prime, with bulging muscles and a bulge where it counted even more. He could feel callouses on his paw pads and knew instinctively that this wasn’t a figure you got in a gym. This was a god-damned powerhouse, good genes and a life of hard work combining into the studly body of a junk-yard dog that could do a lot of creative stuff with the slender little body even now twirling in front of him. Billy had caught him looking and with a twinkle in his eye he pushed his pajama bottoms down, giving Tom a good look at the black tush with an orange stripe running down from under that wagging tail.
“Still not sure, daddy?” he asked, earning himself a short swat on his borrowed behind.
“I’m gonna make you regret showing that off. Now let’s see what goodies these two have packed for us…” he said as they both went through the two travel bags.
“Nothing here… and I mean nothing! No toys, no condoms… no lube!” Tom said as he dug through the luggage.
“Nothing here either. Just lots of outdoors-y clothing. You don’t suppose they just wandered in here by accident?”
“You kiddin’? Remember how long it took us to find this place, with directions? Besides, if anyone straight-laced got here by chance those waivers would have scared them right off. Nah, this is all camping stuff right? So maybe that’s kind of the theme – father and son roughin’ it?”
“I suppose… but you aren’t going to be rough with me, right daddy? After all it’s my first time…” Billy cooed, his hands clasped behind him, his muzzle pointed shyly down as he looked up at him with literal puppy-dog eyes. Fuck, this really was to perfect – they’d done dozens of role-plays along these lines, and those were some of their hottest ones. And now they get to live it out!
“Don’t worry kiddo. Now give daddy a nice look at his little puppy…” he said in a growly tone. He had the attitude to play a big-dick daddy but now that he was riding in over six-feet of hard Doberman muscle he felt like the greatest stud alive.
Billy made sure to put on a show for him, undoing the buttons on his jammies one by one and letting it fall open, revealing the orange of his flat boyish chest and a trim tummy before shrugging it off and turning around. He grabbed the waistband of his bottoms and bent over as he pulled them down to his ankles, lifting his tail and showing a gorgeous tween tush with a pink rosebud that might as well have been virginal. Stepping out of them, the Rottweiler pup twirled around, hands behind his back and his ankles crossed in a way that pushed his thighs together and showed off his pubescent sack and a cute little sheath.
“Do I look cute, daddy?” Billy asked, perfectly combining a seductive pose with an innocent tone.
“Real cute sweetie. A pretty little puppy. Now come and check out what daddy’s got for you…” Tom said, peeling off the clingy shirt and slipping out of his boxers before sitting down and patting his lap.
His legs were slightly parted and Billy’s were spread wide as he took his seat, his puppy-butt slipping down a little until he could feel the fat Rotty sheath pressing into he cleft of his boyish ass. He hugged his lover close, feeling Billy shudder at the sensation of his back resting against a wall of hard-packed canine muscle, the slender young hand drifting down until his small paw found the two hefty black balls hanging under the sheath growing snugger by the second.
“Oohhh, these feel sooo heavy. Poor daddy, are you pent up?”
“That’s right puppy. Daddy’s got a lot of love to give, and he’ll make sure you take every last drop of it.” He said, leaning down to kiss the side of Billy’s neck. Fuck, the size difference was ridiculous, and the puppy sitting on his lap felt like he weighed next to nothing.
“I promise I will daddy! I promise I’ll be such a good bitch for you…” Billy panted, exposing his neck for his ‘daddy’ as he played with the handful between the studly Rottweiler’s legs.
His touch betrayed his experience as he juggled the two swollen testes, breathing deep and moaning cutely as the sheath he was almost sitting on plumped up until a hard, hot tip slipped from the opening. Tom wasn’t sure if his little lover was going to just take him then and there, but Billy had better sense than that. He wriggled around in his “daddy’s” lap, making sure that the tip of the slowly emerging cock did no more than bump against his pubescent rosebud, his hand sliding up and leaving the fat Rotty nuts to dangle as he caressed the thick furry covering of the cock that was going to be reaming his cute little butt all night long.
As the red beast emerged Billy slid back, allowing the tip to poke through between his legs as it grazed his own tiny pouch, the tapered end of the red rod now visible to both of them as it leaked pre like a broken faucet. Fuck, this guy must have really been saving up for tonight! Tom thought as he came face to face with the stud-dog’s red rocket, inch after inch of it as it slid out until the thick red rod was rubbing against the pup’s slender sheath. Billy took the opportunity and pressed his thighs closed, rubbing them together and making Tom growl as the soft fur of the boyish legs tickled the monster he was sporting.
“Ooohh, daddy! It’s so big!” Billy said with genuine awe in his voice. Role-play was one thing, and it was another to find yourself in a tween’s body with a horny stud ready to give you a rutting that would leave a whore walking funny.
“Don’t worry sweetie, daddy’s gonna be nice and gentle. You’re daddy’s big boy, aren’t you? And daddy’s big boy is gonna have no trouble taking daddy’s big cock…” he said, running his hands along the puppy’s trim tummy and the flat boyish chest. Fuck, just the sight of these skinny legs pressed together around his knotted cock made him want to bend his mate over and rut the living daylights out of him. But Tom wasn’t completely lost to common sense. There was a nice young Rotty that would want this body back the way he left it, albeit just a little sore, so the two of them would have to take this slow.
He lifted Billy off his lap with obscene ease, the pup weighing next to nothing as he slid his paws under his arms and hoisted him off. Tom lay down along the length of the bed and gave a nod in the direction of his crotch, and the rosy-red monster resting against his muscular abs. Billy did a good impersonation of an eager and nervous boy awed by the size of the male he was about to give himself to, or maybe it was genuine awe after realizing how much bigger his ‘daddy’ was in these new bodies. The puppy stretched out on top of the muscular canine form with his muzzle already sniffing around the Rotty-rod and his own sheath and the ret tip poking from it pointed at the big dog’s hard pecs.
Tom gave a growl of approval as Billy busied himself down between his legs, sniffing, huffing and licking along the shaft, the still compact knot and the two heavy nuts that would be entirely drained up that puppy-rump by the time their time in these bodies was up. His back was arched and the boyish but was thrust back towards him, tail high and wagging as if drawing his attention to the pink patch under it. The pup for was dry but still smelled of shampoo, and the fact that he’d cleaned thoroughly before slipping his ‘jammies on and brushing his teeth, like a good boy.
He laid his beefy paws on those cheeks, making Billy whimper as the strong fingers groped the perky behind eclipsed by the hard-working hands kneading it. He pushed his thumbs into the orange crease and spread the boyish but wide, his eyes focusing on the winking rosebud that genuinely looked like it had never taken a cock, let alone the monster the boy’s tongue was even now running up and down along.
The idea that he really would be taking the pup’s cherry, or that this will at least be the little Rotty’s first time with his dad’s cock under his tail excited him even more, his powerful neck bending to bring the blocky muzzle closer. Billy had the ‘puppy’ act down and was putting that high boyish voice to good use as he moaned, his tail freezing the moment a broad, silky tongue swiped across the virginal pink pucker.
“Mhhh, such a pretty puppy-pussy… Bet you can’t wait for daddy to fill this up, can you?” he said before giving the twitching orifice another lick, pushing gently with his tongue in order to work the muscles loose. Billy was at a loss for words, but the way he swallowed the tip of the daddy-dog’s cock was response enough…
*******
Billy was no stranger to the Switchboard and the freaky nights to be had at the bizarre hotel, but this was a new one even for him and Tom. This body brought back bitter-sweet memories of the way he’d looked like as a boy – a cute and literally horny little twink – but back in those days he’d never been brave enough to do anything with a grown man, let alone one as huge as the Rottweiler growling under him.
Back when his muzzle had been small the cocks he’d taken in it were as well, and now he had to strain his jaw just to keep his teeth out of the way of the throbbing red missile pointed it him. It was almost scary, but in a good way, and he desperately wanted to go further than a sixty-nine during his honeymoon with Tom. His ‘daddy’ was doing his best, slobbering away between his cheeks as the steady lash of a broad tongue relaxed the instinctive reflex this body had to clench up. He wasn’t getting in yet but Billy could feel his puppy-pucker dimpling gently every with every lick and had little doubt that soon enough that broad tongue would be worming his way in, making him lose and slippery enough to take daddy like a good little puppy-bitch.
Meanwhile he was doing his best to handle the monster leaking against his tongue. It was a thrill to see just how big the red rod was compared to the small, soft paws exploring the throbbing knot and the hard, heavy orbs just behind it. God, when this thing blows it better be either down his throat or up his ass or the room’s gonna be a mess! The idea of the crimson cock spewing down his gullet as his ‘daddy’ pushed his head down against it spurred Billy on to take a few inches more, the hard meat filling his mouth and pressing down on his tongue.
The tongue lapping insistently against his tail-hole finally wriggled past the pink ring and into the virginal puppy-pussy behind it, the blocky muzzle of his ‘daddy’ wedging between his cheeks as the mouthful of Rotty-meat muffled his moan. Tom was going at it without any restraint, as eager and sloppy as a feral dog eating out a bitch in heat. Just the sounds of it were obscene, and the sensation of his tight puppy-pussy being prepared for a night of vigorous rutting had Billy’s eyes rolling back as the tail above the winking pink ring once again began to wag.
Another inch in and Billy felt the tip poke the back of his throat, with a lot of Rottweiler still left to go. Taking deep breaths he did his best to relax and to let the hard cock slip into his gullet, but even though he’d done this before he’d done it with a bigger throat. Even with all his skill there was just no way to breathe once the girthy red rod slid even an inch in, and there was a lot more than an inch left.
Deciding on another course, he let the hard canine cock slip from his mouth, letting out a cute gasp as he focused on the tapered tip spraying pre across his muzzle. Letting out happy-puppy noises he began to kiss, lick and pant up and down the length, the swelling knot, the sheath bunched up behind it and those cum-laden balls. The soft little paws came into play as he whorishly worshiped his daddy’s cock, rubbing and smearing the leaky member against his face as Tom growled in approval and more to the point into his boyish behind.
Taking his eyes off the glistening red spire, Billy spared a glance at the big mirror at the side of the bed, feeling his heart flutter at the obscene sight it revealed - a lithe little puppy sprawled out on a big beefy Rottweiler, worshiping a throbbing canine cock while the huge dog pushed his face under the wagging tail, prepping the waifish puppy for a night of hard rutting. He could feel his own stiffy making a damp patch on Tom’s rock-hard chest and wondered how cute that puppy-pecker would look throbbing and spraying cum while he took the daddy-dog’s gooey load. He went back to bathing the red rod with his tongue, caressing the knot that already looked scary big and still had growing to do. It was only when he felt a swat on his rump that he stopped , figuring that Tom had all he could take of foreplay and was eager to bury his new bone…
*******
“Okay boy, it’s time to show daddy what a good little bitch you really are…” Tom said, moving back until he was reclining against the headboard, beckoning the eager puppy to straddle him.
The cock resting against his rock-hard stomach was scary, but he’d worked Billy’s boypussy until his tongue went numb, leaving the once tight rosebud glistening and slightly agape. His “son’s” little puppy-pecker looked cute as Billy squatted above his crotch, carefully angling the red Rotty rod with his well-tongued pucker, the rosy boyish cocklet jumping when the much bigger tip found the dilated tail-hole and sunk an inch deep into a teeth-grindingly tight little ass.
“HnaaaAaahhh!” Billy gasped, the sound of his pubescent voice making the canine cock twitch and spew pre into the virginal rump. He’d never been attracted to kids, but then again no kid was half as a kinky, submissive bottom as Billy. The monster he was packing would have scared even a boy who was curious about other males, but the look on Billy’s puppy-like face was one of pure lust and determination as he fought to calm the twitching of his tight little pucker.
He could see the rippling of the boyish belly calm as Billy took slow, deep breaths, the virginal tail-hole loosening just enough to let a few more inches slip in. God-damn, did the bog-dog whose body he got really bring his son here to lose his cherry? That’s got to be a first even for a place as freaky as the switchboard, but what an amazing honeymoon memory this will be. Tom was fighting the urge to just buck his hips up and give his mate everything he could feel churning in those fat Rotty-nuts but he kept a grip on both himself and the puppy’s hips as the gasping, moaning waif slowly descended, wincing every once in a while as he took his daddy’s bitch-breeder.
The last few inches of the shaft were particularly tricky, but after some wriggling of his slender hips Billy managed to take everything but the engorged knot throbbing against that taut pink ring. He took deep, ragged breaths, his eyes lidded and his own cocklet leaking like crazy as a girthy canine cock mashed against the pubescent prostate.
“How does it feel, boy? You like daddy’s cock in you?” Tom asked, staying in character. Roleplaying was always fun, but with the pretty little puppy panting as his cock throbbed in him he’d sooner break his arm than break character!
“Ahhh… feel… full…” Billy replied in a panting tone, rubbing a paw along the boyish belly that was looking a little less flat now that daddy’s bone was buried under his tail. “Mpfhh! Don’t think the knot’s going in though…” he said, although he didn’t need to. The puppy-ass was too tight and they’d waited too long, and even with Billy’s whole weight resting on the engorged bulge it was just pressing against his pucker with no hope of slipping in.
“That’s okay honey, daddy will tie you a little later when you’re nice and sloppy. Now show me just how much you like your first cock…” he said, flexing the canine length and drawing a moan from his ‘son’ as the pup began to grind his hips.
“Oooooh daddy, I love it so much! I love being your bitch…” Billy cooed, ending on a whimper as he ground his puppy-pucker against the throbbing knot.
Tom growled as he fought to get a grip on himself. The sight of the waifish tween riding his lap, leaning back and resting his hands against the thick, muscular things of the big Rotty-daddy would have been enough to make him pop without the hottest, tightest little boypussy wrapped around his cock. He folded his arms behind his head and just sat back, willing to let his ‘son’ pump and grind on the thick piece of canine flesh until he fills that tight ass with a torrent of puppy-batter. With any luck he’ll get to watch Billy’s little red rocket twitch and shoot off before that.
“Go on honey, show daddy how much you love having his cock in you. You want daddy to fil you up, don’t you?” 
“Mwaaaaahhh, y-yes! I wanna… I want you to breed me like a real b-bitch!” Billy squeaked, rising just a little as he ground his hips back and forth, his ears folding back as the massive shaft hurried up his puppy-pucker continued to leak, making every slide of his ass along the smooth red length even smoother.
Billy was going slow, no doubt still getting to grips with how much he’d managed to cram into such a small body. But more and more red showed as he got that boyish behind higher every rime, the pink ring clinging to the big canine rod before he slid back down until everything but the knot was buried in the twitching puppy-pussy.
Billy was making the sort of noises no twelve-year-old boy had ever made, but he was making them in a twelve-year-old’s voice and that only added fuel to the flames, urging him to move faster and slide further along his “daddy’s” cock as his own red rod bounced, showing a tiny little know swelling as the immature prostate took a pounding every time the tapered tip of Tom’s mammoth member grazed it.
“D-aaAaaahh-daddy! I’m gonna… gonna…” Billy moaned, the twitching of his rosy rocket making it clear what was gonna happen.
“Good boy. Show daddy how a proper bitch cums…” he said, his deep, growly tone pushing his ‘son’ over the edge.
The slender puppy-pecker twitched, sending thin ropes of sum spraying over the massive orange chest and abs, little wet streaks arcing through the air as the tiny puppy-pouch pulsed and the moaning boy rode the slick red cock embedded in his ass. The clenching of the already tight boypussy had Tom clenching his jaw, and when Billy fell forward in exhaustion on top of him he knew he could get his. The little cock was still going, making a warm, wet stain between them as he laid his enormous paws on the perky behind and began to buck up into his diminutive mate.
Billy hadn’t even come down from his orgasm when his ‘daddy’ started pumping his rear in short, shallow jabs, strong fingers digging into pliant young flesh as the big dog growled deep enough for him to feel it as he lay against his chest. Tom did his best to hold back, building up the climax as much as he could as he bared his teeth and folded his ears back. With a snarl he finally let loose, pulling Billy back until the throbbing knot was pressed tight against his straining pucker. The puppy whimpered into his neck as the engorged shaft twitched and those heavy black balls pulled up, pulsing as they churned out a big dose of doggy-milk.
Stars were dancing in the dim corners of his vision by the time he felt the first rope spray from his tip and gush deep into the freshly deflowered puppy resting on top of him, the snug behind clamping down on instinct to keep as much of daddy’s juices inside as possible. It took about five spurts for the puppy-pussy to reach its limit, and without a knot every squirt from then on gushed through the tight seal his pink ring had around the throbbing monster impaling it. The deluge seemed endless and Tom had to wonder just how long this Rottweiler had been saving up for before he brought his son to the freakiest place in the world, knowing that some lucky bastard would wind up emptying those balls up his little boy’s tail-hole.Billy was clenching tight but the cum was leaking and squirting around his shaft, making a huge. It would be tempting to let Billy clean his daddy up, but that seemed like a waste of time and some much needed lube…
“Nghooohhh God… there’s so… much…” the pup on top of him panted, little shudders running along his body as a torrent of warm dog-spunk squirted and leaked around the fat red rod stuck up his little behind. When he got some strength back in those slender boyish limbs he crawled up and planted a kiss on his daddy’s muzzle, sliding almost all the way off the canine erection as it continued to seed his pubescent ass.
They spent a minute or so making out with Tom running his beefy hands over the waifish body of the freshly fucked young boy, enjoying the way Billy’s muscles trembled under the touch of those big strong paws. When he reached the tight little ass he grabbed the firm cheeks and spread them side, making the ‘puppy’ gasp as his pucker lost the grip on the now obscenely slick cock, the tip slipping out followed by a gush of Rottweiler cum.
“Did… did you like my pussy daddy?” Billy asked in a breathy voice, still in character and still up for more, considering he was saying just the right things to keep Tom riled up.
In response he let one thick finger slip into the crease of the boy’s ass and then into the still gaping hole drooling warm, gooey incestuous spunk. Billy moaned out and arched his back, the slick little ring pulsing and clenching but not nearly as hard as it did before. Tom pushed the thick digit deeper in, enjoying the look on that puppy-dog face as he stirred the mess and finger-fucked his little boy who moaned softly and eagerly every time the paw pad came close to his young prostate.
“You were a very good girl for daddy, but you didn’t take the knot did you?” Tom asked, squeezing hard on the boyish butt and smiling at the gasp that coaxed from his little lover.
“N-no daddy… you were too big for me…”
“So now that you’ve were such a good little slut for me, it’s time to show daddy you can be a good bitch for him to…” he said, slipping out of the snug puppy-pussy and hefting Billy off of him with amazing ease. This wasn’t his first time in another person’s body, but this thing was a powerhouse in every way. Definitely something that got Tom’s imagination going… “So what does a bitch do to show she wants puppies?” he asked, and to no one’s surprise Billy scrambled to show him.
His cock had barely begin to shrink, but the sight of the puppy on all fours with his tail raised put a stop to that. He leaned down and spread the perky cheeks apart, taking a good look at what had until recently looked like a virginal little tail-hole. He’d been worried that they might have gone too far, but apart from the mess and the slight gape that made his cock twitch the gooey little pucker looked perfect – it was even winking as if begging for more. Tom was sure the pup had never had anything like his dad’s cock up his ass before, but for all he knew the boy had been giving his ass up to other kids in school. He still seemed a bit young for that, but neither he nor Billy could really judge these two. Not when they had better things to do all night.
Placing his hands on the boyish hips, he let his heavy red length slap down against the messy crease of that presented behind, thrilling at the sight of his heavy paws and obscenely big shaft against such a cute little body. Tonight really was a jackpot, their hottest sessions and fantasies brought to life, and Tom was determined to make every minute memorable. Still, there was no point in rushing things, so he did nothing but let his hot red cock rest in the puppy’s crack, even when Billy began to whimper.
“Daddy, you’re teasin’ me!” Billy moaned, a petulant tone that was dead on for the role of a slutty little boy eager for his daddy’s cock.
“That’s right honey. If you want daddy to take you like a bitch you have to show me how much you want it. So come on boy, beg for it.” He said, his blunt muzzle splitting into a grin as the puppy’s slender tail began to wag.
“Oooooh, please daddy, don’t be mean!” his ‘son’ moaned, flexing his back and moving his ass back and forth so that the cum-smeared cock slid between his cheeks. “I’ll be a good bitch for you! I’ll take your knot, take every drop of your cum… Please daddy, tie my butt and make my puppy-pecker squirt again!” the ‘pup’ begged, all the while letting the big dog’s big cock glide along his crack. He would push back until the knot was rubbing against his drooling rosebud and slide forward until the tapered tip almost caught and speared the winking orifice.
After feasting his eyes and ears, Tom positioned himself behind the eager bitchboi, growling lustily as his beefy hands easily griped the slim waist just above his hips. He had to spread his legs wider just to lower himself to the level of the pubescent pup, following the tip of his cock with his gaze as it slid down until he could feel warm, messy skin against it. One sharp buck was enough to push several inches into the boy in the blink of an eye, his squeal masking the wet sound of cum being forced out as the pucker clenched reflexively, trying in vain to expel the sudden intruder.
The rest of him went in slow, his eyes glued to the perky little ass as it quivered, the pink ring now almost invisible as it dimpled in, stretched taut around a cock that would have had a grown woman squealing. Watching Billy’s cute boy-face while he rode his cock had been great, and the sight of the puppy-cock throbbing and spraying from nothing but daddy’s cock grinding his prostate had been a delight, but there was something thrilling about taking the young canine like this – on all fours with that cute back arched, the firm little behind thrust out and tail flagged even as it was stuffed.
Soon enough there was nothing left but the knot, and even though he knew he’d have to tie his little bitch soon or never, he still wanted to enjoy thrusting into Billy’s boyish behind for as long as he could. He’d only ever once been in a body with a knot, and that had been a fox. The thing at the base of his cock was the real deal – a hard, hot bitch-plug that would ensure his puppy got a belly-full of his daddy’s spunk.
He ground his knot against the quivering tail-hole just for fun before pulling himself back and pulling the puppy’s hips off him at the same time, relishing the sight of the pink ring clinging to the veiny red rod. He pulled Billy back to meet his thrust, the force of it pumping out the last of his previous load from the whimpering pup, making room for the new batch. And he had little doubt he had plenty left. His balls still looked heavy and his cock didn’t go down even after he’d rutted ‘his’ pup. This big dog must have intentionally gone dry for a while just to make sure his son got filled to the brim at the switchboard, and he could feel the heavy black nuts slapping the puppy’s pair every time he thrust home and pulled the boy to meet his thrust.
A real twelve year old, even one who loved serving up his puppy-pussy, would have been whimpering and begging the big dog taking him not to tie, but then again it wasn’t really a boy at the wheel, so to speak. Before he tied the knot, Billy had taken plenty of them, and some of the butt-plugs Tom himself had pushed into the goat had been downright scary-looking. For all his slutty-puppy act he knew how to do this – he was breathing as deep as he could and fighting the urge to clamp down when the tip of the girthy Rottweiler cock grazed his pubescent prostate. The pink pucker was also nice and messy, and dilating a little more each time the bulge bumped against it.
“Get ready boy, daddy’s about to make you his bitch…” Tom growled, moving one hand to grip the base of Billy’s wagging tail. He drew half-way out of the slippery puppy-tunnel before thrusting with all his might and pulling the perky little ass back. There was less than a second of resistance before the loose, messy ring yielded, swallowing his daddy’s knot and clenching tight around the slim base behind it.
“NghhhhyaaaAaaaahhh!” Billy cried out, thrown his head back as his whole body tensed, his borrowed behind adjusting to the already fat knot as it grew bigger with every beat of the big dog’s heart.
Tom growled from the sensation of a warm, hot little vise gripping him like nothing ever had before, the cutest, tightest little ass he’d ever fucked pulsing around his cock as it throbbed and flexed. The puppy-pecker looked distended and as Billy laid a paw on his orange belly Tom wondered if he could feel a little bulge now that he’d taken everything this big mutt had swinging between his legs. If not, he’ll definitely feel a bump once he was finished pumping his rump.
Eager to breed the boy, Tom began to tug and grind, his fingers digging into the firm flesh of the puppy-‘s behind as the boy’s insides caressed his cock with even the slightest of movements. It would be even more intense for Billy, as evidenced by the strange, unintelligible cries and moans coming from his little muzzle. It was hard enough to role-play when you had a knot up your ass, but it was impossible when that knot was being ground as it throbbed against your prostate. Billy was so far gone he couldn’t even warn his daddy that he was coming, but when the gasps rose in pitch and the pucker began to clench and pulse like crazy around the slim part of Tom’s cock, the Rottweiler didn’t need to be told. Craning his neck he saw little streaks of puppy-spunk streaking wildly over the bedspread as his grinding and tugging made the pubescent rocket swing and flop around.
He wasn’t far off either, and with a growl Tom threw one paw under the little Rotty’s chest and easily hauled the pup into a kneeling position. He could feel Billy’s heart thudding against his palm as his ‘son’ rode out a mind-blowing orgasm, the little red cock still twitching even though that snug little pouch under it seemed to have run dry. With another growl Tom bent his neck down and caught a muzzle-full of the pup’s scruff, giving him a firm but gentle mating bite as his own swollen nuts pulled up, the knotted cock preparing to once again flood the puppy’s body with his dad’s seed.
The sack twitched, the shaft throbbed and the tip sprayed rope after warm rope of doggy-milk, without so much as a drop leaking from the plugged pup. Still in his daze, Billy moved one paw to his belly, with tom covering the little hand with his own, imagining how it must feel like for his little lover to take blast after blast of cum and being forced to keep every little drop in that tiny rump and that trim tummy.
Deep down Tom had always felt his stature didn’t live up to his attitude and he was savoring how big he was as he held the quivering pup against him and how to best take advantage of that fact. Acting on a whim, he gripped Billy’s pubescent body as pushed away, landing on his broad back and taking the squealing pup along with him.
“Daddy! You’re acting sill…” Billy began, but stopped when the bog Rottweiler swept both his legs up in one paw, getting a good grip before pushing his shoulder and twisting.
Tom grinned at the sight and the sound of the stunned pup as he twisted him around on his cock, the slender body weighing next to nothing as his muscular limbs turned him until he was the other way around. Even Billy seemed amazed as he laid his legs along either side of the big daddy-dog still firmly tied to him, sprawling out on that muscular chest as every little movement of the fully engorged knot ground against his prostate and threatened to make him cum again.
“There’s a good little puppy. You like being tied to daddy?” He asked, trailing his fingers down the little Rotty’s back until he reached the base of the slender tail. A question only for show, since he could feel the little stiffy against his abs and knew Billy was a few choice fondles away from going over the edge again.
“Mhhh, yes daddy… you’re –mwah!- so b-big… I feel s-so fuh… fuh…” Billy whimpered as Billy groped his little ass hard, fingers sinking into firm flesh and making eh pubescent but clench around the monster buried in it. The ‘puppy’ never finished his sentence, his body quivering as the hard little shaft spewed out a few watery spurts against the big dog’s belly while Tom savored the sight of his little lover writhing against him as he came yet again…
*******
“Ooohhh daddy, you’re so strong…” cooed the puppy clinging to him, seated on Tom’s two beefy palms as the clung to the big dog with his arms around the muscular Rottweiler neck and his legs wrapped around his doggy-daddy’s hips.
“Damn straight puppy! Daddy’s been waiting a long while to make a bitch out of his little boy…” he growled lustily, spreading the perky cheeks as cum splattered from the well-rutted puppy-cunt.
Billy had taken more than the little body could hold, and it showed on the boyish body. Cum had soaked into the orange fur of his ass and white streaks could be seen on his head, overflow from the blowjob he’d just given his ‘daddy’. And to their delight the huge Rottweiler still had more to give his little bitchboi, as evidenced by the heavy red erection even now standing poised to sink into the thoroughly bred little pucker.
Tom felt the drip of cum falling from Billy’s gaping boypussy fall on the thick red meat, a sure sign he had the pup where he wanted him. The once virginal ring was a thrilling mess as it kissed and almost immediately swallowed several inches on incestuous canine flesh. Billy whimpery moans were music to his ears as he lowered the perky canine behind and let his ‘son’ slide all the way down, growling as the messy tail-hole swallowed his knot.
His muscles bunched along the powerful arms but lifting the moaning puppy off his cock still felt effortless, like moving a moaning panting doll around. He had to admit he was getting off on how big and strong this body was, and Billy was sure as hell enjoying being a dainty little puppy, moaning and straining as the thickening knot pushed in and tugged out of his thoroughly rutted hole.
“Ahhhhhhnn! D-daddy, you’re gonna r-ruin my little pussy…” the puppy moaned as Tom gave a sharp buck the next time the pups’ ass slid down along his length.
“Ohh, had enough, huh? Maybe daddy should just pull out and tuck you in for the night…” he said, lifting Billy up and up until his pucker was just barely gripping the tapered tip of the big dog’s shaft.
“Gyahhh! No! Please daddy, don’t stop! I’ll – aaaaHhhhhh!- be a g-good bitch! P-please daddy, fuck me harder! B-breed my puppy pussy… kno-oooOommghhh!-t me, rut me…” Billy stammered, a steady stream of obscene pleas interrupted only by gasps, moans and squeals as tom did what he’d begged him for.
His ‘boy’ really seemed to have taken the threat seriously, enough to spend what little breath he could catch on pleading for his daddy to fuck him, to fill him up and knot him until he was sore. The stream of lewd pleas were interrupted by barks and shrieks, loud enough to make Tom wonder just how soundproofed these rooms were. He wondered how the real Rottweiler’s would feel if they heard the sort of noises he was coaxing from the pup as he pumped him up and down his dad’s cock.
Billy was so lost that when he finally came he howled, his little cock twitching but failing to produce any puppy-milk. The boy’s tiny balls had been pumped dry, but the pair Tom had swinging between his legs could still churn out a nice hot load for a good little bitch. He felt Billy’s hold on his neck go slack, his eyes lidded as he tried and failed to form words in the aftermath of his climax. He was fighting the exhaustion that was taking its toll on the body of a growing pup, and when the hands finally slipped from around his neck and fell limp to the side Tom guessed Billy had checked out.
His next trust pushed the boy over but his grip on those waifish hips was strong and the throbbing canine cock stayed buried in that still quivering puppy-pussy. His little pups whole body fell limp, the head thrown back with a pink tongue hanging from the cute muzzle as his big doggy-daddy continued to breed, holding the spent boy like he was a doll. Billy had to admit the boy was beautiful, with his back bent, the dark nipples hard on that flat boyish chest and with a subtle bulge showing on his orange belly every time Tom drove himself in. Every once in a while Billy would murmur something, or flail with a hand, hoping to wrap the arm around his rutting daddy again, but for the most part he remained a sexy little ragdoll, taking a pounding from the growling male gripping his hips and driving his knot over and over into the already rutted pucker.
Knowing that he was running out of time if he wanted to tie with his little sleeping beauty again, Tom grit his teeth and set his feet, delivering powerful thrusts as he pulled the boyish hips back to meet every lunge. Three times he almost but not quite managed, and as he growled on his fourth thrust he felt the puppy-pussy stretch around the swollen bulge before it sucked the whole red rod in. He threw his head back and groaned as he let lose yet another torrent, the sensation of a knot throbbing in his ass bringing Billy around just enough for him to mewl cutely before his light went out again.
Acting on a whim and still riding his orgasmic high, Tom carefully let go of Billy’s hips, grinning like a wolf as the weight of the pup tugged on his knot but failed to pull free from the engorged mass still throbbing within that snug little boypussy. He ran a hand down the puppy’s tummy and lower, playing idly with the little sheath and empty pouch as he considered what to do once Billy comes to.
*******
“Hey, have you wondered if they can switch us back if we leave during the night…” he said, toying with the spermy mess he’d made of Billy’s puppy-cunt.
“You… you can’t mean to…” his little lover said, a trail of saliva still connecting the shocked muzzle to the cock it had been nursing on until a moment ago.
“Not forever, don’t worry. But you gotta admit that this is the best pair we ever got, and it just so perfect for us. And one night hardly seems like a proper honeymoon, now does it?” he said, enjoying the look of intense concentration on the young face inches away from his big red rod…
*******
“I don’t care what I signed, or what you have to do, but I want you to put us back to normal right god-damned now!” Ace snarled, or at least tried to. He doubted that creepy ferret would be this calm if he was in his own body, and not a 5 foot tall cat!
“Like I said, Sir everything will be back to normal in the morning, if you’d just wait patiently…”
“Wait for what? You won’t even tell me who’s got our bodies or where they… where we are!”
“It’s all a part of the confidentiality clause which you signed.”
“I don’t give a rat’s ass! You switch us back right now before my son gets traumatized by all this crap!” he snarled, pointing to the goat beside him.
Junior, for his part, stayed quiet. Usually his dad scared him a little when he got angry, but with him now standing more than a head shorter he was trying not to grin at the sight of his normally huge father hissing and fussing in the body of a cat. After all, if they were gonna go back in the morning anyway, where was the harm in being an adult for one night?
