Here's a fun, messy story done for Burn-the-kitsune, featuring their kitsune Ember and their many tailmaws!

This is the first RNG-based story I've done in a good while, so admittedly it was a bit tricky to write, but I had lots of fun doing it! Growth and multi is always a treat to do, especially together, and Ember was a perfect fit for it. There's lots of multi for lots of things in this story, and I can't really tag each individual part that had multi, so if you aren't into it be warned. As tends to be the case with stories like this there's a lot of kinks to keep track of, so I might have missed some things while tagging.

Ember the kitsune was relaxing at home one afternoon, making themselves a snack in the kitchen, when they heard their doorbell ring. Their many tailmaws became excited at the noise, trying to pull them toward the door, and they chuckled as they walked over. "Calm down everyone, I'll see who it is." They reassured their tails, giving one a pet. They peeked out the door's window to see nobody there, and instead there was a large cardboard box left on the doorstep. They raised an eyebrow, opening the door up and taking a better look outside, yet still seeing nobody. "Weird.." They mumbled, picking up the box and carrying it inside, closing the door behind them with a paw.

They dropped the box on the kitchen counter, using a pair of scissors to slice through the tape on top, opening it up to see it was filled with packing peanuts, digging through that to find a small, white box buried inside. They lifted it out, discovering it was surprisingly heavy, only getting even more curious. They pulled the box's lid off, finally seeing what was inside: A small, ornate egg made of different glittering stones, gold lines decorating its surface like veins.

"What the hell?" They thought to themselves, trying to take the egg out of the box, but the moment their fingers touched it a shock went through their body and made them yelp, jumping back in surprise.

After shaking their hand a few times and letting the brief pain wear off they gave the egg a hesitant poke, getting no shock this time and deeming it safe to pull out- which wasn't easy, since it was far heavier than it looked. They looked at it from different angles, holding it up in the light, the fancy egg seemingly changing colours as they turned it. They very carefully set it down on the counter, looking at the cardboard box and finding no sort of stickers or any indication of who sent it or where it came from. They shrugged, nonchalantly going back to making their snack, going to the couch afterward to happily munch away on it, feeding some to their tailmaws, or the mouths on their palms.

Once they were finished with their snack they made their way into their washroom, stripping down and stepping into their extra-large shower and turning on the hot water, letting out a happy sigh from the sensation of the warmth soaking into their fur all over their body. Soon they felt an unfamiliar tingling go down their spine, making them pause their cleansing until the sensation faded, or rather, it changed, turning from a tingling feeling to an intense heat focused on certain parts of their body, namely their chest and their crotch, and they couldn't help but let out a quiet moan as their cock peeked out from their sheath.

They huffed loudly, unsure of why they were feeling so horny all of a sudden, slowly lowering a hand down to rub it between their legs, gently fingering their sensitive slit behind their sack while their shaft continued growing harder. Their other hand went to their chest, squeezing and rubbing one of their breasts while the water poured over them. Soon they felt something unexpected though: below their perky tits, a second pair of nipples had grown in under their fur, chest swelling out until they had a second row of breasts equally as big as the first. It wasn't exactly the first time they grew an extra set of tits- being a shapeshifter it wasn't something that'd be difficult to do, but their surprise here came from the fact that it wasn't intended at all, happening completely out of their control. In fact, they couldn't even change it back. It seemed like they entirely lost control of their shapeshifting!

Their cheeks flushed hot as they realized the gravity of their situation, finding themselves unable to revert that change or even make other changes to their body. They were definitely a little bit worried, but a bigger part of them was more just curious about where it would go and what would happen to them. For now, they took a deep breath in while their heart pounded, and then they kept on stroking and squeezing and rubbing themselves, making sure to give plenty of attention to both rows of breasts.

Their many tailmaws seemed a bit jostled as another change began, Ember panting and leaning forward against one of the shower walls, spreading their legs as an intense pressure grew from their ass. They whimpered and whined as a second set of legs grew out from behind, pushing further out until they had a large taur body with its own set of already needy genitals, half of their two-hundred tailmaws moved to its rump while the other half remained at their own butt on the base of the taurish body. They took a few steps in place to adjust to the new feelings, unable to reach back to touch that rear set of genitalia, but their tailmaws were a step ahead of them. One went between their hind legs, taking their knotted cock and balls right into that warm and wet mouth, sucking hard and immediately getting a shaky moan out of Ember. Two more tailmaws curled around to their ass, not waiting a single moment to stick their tongues deep into their waiting pussy and tailhole, giving them a good stretch while they trembled with pleasure, doing all they could just to stay standing up while their tailmaws took control.

They didn't get much time to adjust before yet another transformation began, once again focused on their hindquarters. The tailmaw that'd been slowly tonguefucking their ass huffed as it was squished between two other tails, those two maws honing in on another two tailholes that formed behind the kitsune's slit. They squeaked in surprise as they felt those hungry mouths lick and kiss their rump, all three of their tailholes reflexively tightening up while they were teased. It made it even harder to stay standing, the pleasure making all four of their legs tremble.

Ember then noticed something else, not that it should've been surprising. Along with the other transformations, it seemed like they grew taller as well! Not by too much yet, only a few small inches, but they could tell that it was going to get quite out of hand before long. They turned off the shower, stepping out and grabbing the closest towel to try drying themself off. They were having trouble reaching most of their taur body, struggling to reach back so far, when they felt a tightness in their crotches. Their furry sacks quickly became heavier, stretching taut as four more testicles grew on both their front and rear sets of genitals, the increased production already causing more precum to drip from both cocks, some getting right on the floor and some leaking into a waiting tailmaw's mouth.

They couldn't hold back any longer, returning to touching themselves with both hands while leaning against a wall, gripping tight to their cock and lightly squeezing their numerous balls. That's when they lost control of something else, and the mouths on their hands opened up to let out many of their long and sinuous tongues, tongues licking all over sensitive bits or curling around and squeezing things, smothering their knotty dick in soft, drooly tongueflesh. They gasped and flinched, even more aroused and embarrassed as they lost more control of their body and shapeshifting, yet it felt too good for them to keep trying to stop it.

They moaned out with bliss, idly thrusting into their hands and tails while they were licked, sucked, and fucked. They hardly even noticed as their mouths all over started to drool far more than they already were, making slick messes that dripped down their body and made puddles on the floor. It didn't take long for all of it to bring them to a climax, their holes clenching down hard and their balls drawing up tight, their cocks bulging slightly as they started to pump out a massive load of kitsune cum. Fat ropes of creamy seed splattered along the floor, only the tip of their dick free while the rest was squeezed and milked by many tongues, their second cock pulsing inside one of their tails' mouths and pouring hot cum down its throat. Pussy juice squirted down both pairs of legs, mixing with the puddles of cum and saliva on the floor.

Their orgasm continued for what felt like an eternity, though it was only a few minutes before it finally finished. They panted tiredly as they came to their senses, cheeks flushed bright red, and they slowly stumbled out of the bathroom while their tails continued pleasuring them without end, sometimes switching places so more of them got a turn. They only made it as far as the bathroom door before could feel pressure building rapidly in their teats, and they didn't even have time to raise a hand up before milk began to heavily gush from all four nipples, squirting out nonstop without any of their aid.

"O-ohh gosh.." They huffed, staring at the mess they were making, utterly distracted for a few long seconds before snapping out of it. They reminded themselves that they had to get outside before they became too large, but they only took a single heavy step before stopping, the movement making their overfilled breasts bounce in an oddly pleasant way, a soft groan escaping their throat. Without even thinking they raised a hand to one of their upper tits, lifting it right up so they could latch onto that sensitive nipple and start sucking, extra thick ropes of precum shooting from their cocks once they felt the pleasure of drinking from their own chest. Rich, warm milk flooded their mouth and they didn't hesitate to gulp it down again and again, even as a tailmaw took its chance and latched onto a different tit, sucking down their cream while their free hand was left to tend to their other two breasts by squeezing and massaging them again and again, coaxing even more milk out to drink and make a mess with.

Not even a minute passed before they started to go through another change, the already excessive flow of milk becoming even heavier as their areolae grew wider, nipples shifting to make room for more of them to form, each of their four tits capped with a quarter of stiff, sensitive nipples. They moaned against their chest, squeezing it tighter and forcing even more milk to gush into their hungry maw. Even swallowing as much as they could it still dribbled and leaked from their lips, getting all over their chest, hands, and the floor below. Their stomach was full but they couldn't stop drinking more, slowly distending their belly outward and even filling the gut of their taurish half. They couldn't stop even if they wanted to, one of their tailmaws still suckling away- almost fully swallowing the breast it was drinking from- and both of their hand mouths had stuck themselves to the two free milk tanks.

They were given all sorts of attention all over, who knows how many tailmaws stuffing their holes from behind with multiple tongues in each, some going for their pussy up front to ram tongues so deep that even their womb was penetrated, bulging their stomach despite how it swelled with milk. They were helpless to the incoming wave of pleasure as they were brought to another orgasm, tiredly whimpering and sliding to the floor, their lower half flopped onto its side and their upper half pushing itself up on an elbow. They trembled in their own mess, squirting hard onto their tails and legs, cumming even more than the first time as their massive nuts produced thick semen nonstop. Even their tits gushed harder with everything else, nearly making them choke on the flow of milk- almost making their head choke on it at least, their hands and tails handling it quite fine.

Their climax eventually finished but they could still barely think, blurry eyes looking toward the door as they let their teat slip from their milk-covered muzzle. A faint thought went through their head, the kitsune starting to regain their senses but still struggling to think. "Gotta get out of here.." They thought as they pulled their hands away from their chest and slowly rose to their feet, almost slipping in the mixed fluids that continued pouring out, hardly able to remember why they wanted to get outside despite already being close to double their usual height with no signs of their growth stopping- not only were they larger overall but they'd grown quite a bit curvier and more well-endowed, balls hanging lower between their legs and breasts swelling in size, even their hips and ass getting wider and larger. They put all of their efforts toward stopping their transformations, trudging toward the front door while continuing to drip and leak all over the place.

They stopped to take a breath once they reached the front door, slowly opening it up before trying to get through. They didn't make it far though, their hips barely making it through before coming to a stop, but not on purpose. Their home was rather spacious, including some extra wide doorways, but with how they grew and changed they were simply too large to make it through, their taur body getting stuck in the frame. "N-no worries, I'll just back up.." They told themselves, trying to step back inside, but they couldn't budge. Their big paws simply slid on the floor as they tried pushing and pulling themselves, their body so stuck in the door that they couldn't get in or out. It only took another moment for them to realize that anyone who passed by would be able to see them, their chest and crotch fully exposed and unable to be hidden, one of their tailmaws still drinking from one of their tits and their cock dripping precum out in the open. They lived a bit out of the city so there weren't too many people around, but even with the size of their lawn there was a clear and easy view to the front door where they were stuck.

Their embarrassment and worry was enough to make their concentration slip, another transformation starting immediately. Things suddenly felt very tight in their rump, and a moment later a burst of pleasure shot through every inch of their body, the kitsune nearly cumming on the spot and shooting fat spurts of off-white precum. The tailmaws stuffing their formerly-tight tailholes grinded their tongues hard against their anal walls, pushing and rubbing against their sensitive prostate.. or rather, their prostates, twelve more of them having formed together, pressing against one another and helping to producing what could only be considered an excessive amount of cum. There were so many of them and they were all so large that there was a considerable bulge in Ember's taint, making their slit look extra big and puffy, not to mention far more sensitive than it already was.

With their tailmaws stimulating them so intensely, it didn't take long at all for them to be forced into another powerful orgasm, releasing an unrestrained cry of pleasure that echoed through the area. Their hands gripped tight to the doorframe, claws digging right into it. If they weren't stuck they sure as hell would've fallen right to the ground, their body putting all of its strength toward pumping out an absurd amount of semen, their dicks- which were almost two feet long at that point- stretched wide as cum exploded out. The tailmaw between their hind legs bloated out from the sudden flood before it adjusted to it, taking massive gulps and letting all of that seed go right to the taur body's stomach, quickly swelling it outward with loud sloshes and gurgles, getting them even more stuck. Their front dick throbbed so hard that it smacked against their belly, spraying a veritable geyser of cum across their lawn, their tits joining in by continuing to gush milk out even if they hadn't all been getting stimulation.

Their many balls and prostates tensed and bulged so hard it felt like they might burst, producing far more cum than necessary just to immediately pump it out, their dick spraying semen like a firehose all over their lawn, some reaching far enough to get all over the road. A few more tailmaws managed to get under them while they were stuck in the door, immediately giving all sorts of worship to their sensitive, full nuts, giving it all sorts of licks and kisses, even sucking on them while they throbbed and pulsed.

They were in the middle of their orgasm when something changed, happening so quickly that they didn't even have time to react as their already overproductive balls and prostates went into overdrive. The poor tailmaw that was drinking from their cock was practically shot off by the sudden, explosive increase of cum, a mess spewing out of it as it was hosed down with even more jizz, other tailmaws coming in close to catch some of their own- both of the kitsune's stomachs were past capacity, so full of cum that they looked pregnant, but their tails didn't seem to have any plans on stopping, and their orgasm didn't seem like it was going to stop either. It was practically raining their virile cum with how much was pouring from their cocks, the one in their rear half slowly flooding the house while the one in front sprayed all over their lawn, roof, and the surrounding trees, painting the area white in steamy cum. There weren't even pauses between spurts, more like a constant, unending stream that kept on coming and coming.

Each change and transformation came sooner than the last, giving Ember less and less time to adjust to the new sensations in the midst of the nonstop mind-numbing stimulation. Bulges formed on their crotches, pushing out and rapidly gaining size, changing shapes and colours, becoming very sensitive all of a sudden, making Ember dizzy from pleasure as every last one of them started to gush out cum just as hard as their cocks, or at least their first two. Over twenty more had grown with ten between each set of legs, those numerous shafts having different colours and shapes- from knotted cocks to foreskinned phalluses, to equine pillars of meat- but were all similar in size, all throbbing against eachother and pouring out equally massive showers of semen, taking the already inconceivable pleasure to new heights.

Many of the kitsune's hungry tailmaws immediately lashed out, deepthroating flares and licking across barbs, sucking on knots and kissing thick ridges. All of it went straight to Ember's gravid-looking stomachs, making them audibly groan and stretch louder the more they were filled. Over that noise, their own moaning, and the sound of their cum spraying and splattering onto everything, they couldn't hear the noise of the doorframe they were trapped in and the walls around it creaking from their unending growth, their stomach squished quite a bit yet still growing out. It didn't feel like they were going to stop cumming any time soon, especially with how their tails were milking so many of their sensitive pricks, or stretching their needy holes around multitudes of drooling tongues to milk them from the inside.

It didn't take long for the creaking to turn into cracking, their form large enough to really start breaking things while they were helpless to stop it. With a loud crash they finally burst free, not that they had the strength to do it on purpose at that point, a large hole left in the front of their house as debris fell to the ground. A mess of cum spilled outside to their sides, the inside of their home filled with an inches-deep pool of cream that was now able to pour out. The doorframe wasn't the only thing filled past its limit, both of the kitsune-taur's bellies being filled too fast to contain everything they were being given, taking the closest ways out to alleviate some pressure. First it descended deeper into their body from their taurish half's stomach, trying to escape from their tailholes. It poured all over their tailmaws' tongues and splashed out, a large amount of it being gulped right down and circulating back into their belly. Their upper half's stomach took a different route, the excess fluids traveling up rather than down. Ember only had the briefest warning, their throat feeling especially warm and the taste of cum coating the back of their tongue, their horny mind unable to process what was happening before thick, white seed gushed forth from their mouth. They made a defeated whimper, unable to lay down properly with how massive their stomach was getting, so big that it was resting most of its weight on the ground and still pulling them down. They simply slumped on top of it, paws barely even able to reach the floor now, the constant barrage of stimulation preventing them from falling asleep, semen continuing to pour from both ends of their body.

They mustered up the strength to glance back into their cum drenched house, something colourful catching their eye. It was none other than the mysterious egg that'd arrived earlier, still sitting on their counter where they left it. The cum-covered gears in their head turned as they stared at it, and they soon realized that it must've been the culprit for them losing control of their shapeshifting! They tried reaching back to it, hoping to see if they could reverse its effects somehow, but it was still far out of their reach, and they couldn't exactly walk over. At least it was out of reach for their hands, a tail sticking itself far out behind them, its long tongue extending out until it was able to reach the fancy gem egg, tongue wrapping around it.. before its tongue quickly pulled back into its mouth, snapping its maw shut as it swallowed the egg whole, letting it slide down its throat into Ember's belly. Their eyes went wide, but they couldn't say anything about it or even gasp in shock thanks to the nut-batter that continued to pour from their mouth.

A heavy rush surged through their body, their fur standing on end and their tailmaws even pausing for the briefest moment. Their whole body groaned and creaked before going through a massive, instantaneous growth spurt, the kitsune making a gargled yelp as they grew a few feet taller in just a moment, their assets growing even more while their orgasm continued without end. More of the front of their house crumbled from their growth, and even though it made them tall enough to properly stand without their belly dragging on the floor, they were too weak to do anything about it.. especially as their body shifted, and from their sides they grew far more than what they expected. It felt like everything was in slow motion yet simultaneously as quick as a flash, their body tingling heavily as another body grew from their side, connected by the hips- at least the front hips- and growing its own four paws, an upper body with two arms and four milky tits, a tight pussy and throbbing cock forming on both of its crotches with sacks containing several cum-churning balls to match, that body adorned with two hundred of its own tailmaws.. and then another full body quickly formed on their other side, and another, and another, and another.

By the time that transformation was complete, it seemed that Ember had over twenty new bodies attached together, all identical to eachother with their own limbs, genitals, and heads. It was an unusual yet blissful feeling, Ember getting so many sensations from every inch of every body, including the pleasure. All of those sensations were shared between every body and every head, making a sort of pleasure feedback loop that was rapidly getting stronger. The mess they made already looked small compared to what had begun, all of their new genitalia ejaculating hard and messily, hundreds of cocks spraying cum all over the place. Plenty of those many dicks were long enough for some of Ember's heads to suck on (or deepthroat), or flexible enough to bend around between their legs to get stuffed into pussies or tailholes, every stomach getting filled one way or another and all swelling up, more than a few of Ember's bodies spewing cum from both ends just like their first did. Their tailmaws had more than their fair share of fun, doing everything from gently kissing over Ember's bodies and licking their cocks, to tails pushing themselves deep into pussies and tailholes.

The entire front of their house had been knocked down by their increasing size and number of bodies, yet they couldn't stop themselves from continuing to change. Their embarrassment was growing too, especially once they noticed that some of their neighbours had come to see the show, watching from the road and getting showered in kitsune seed.. maybe they weren't watching much anymore, too busy getting themselves off on their own or with eachother, enjoying the mess they were being bathed in.

Obviously it didn't take long for the next transformation, especially after one of Ember's tails had swallowed the egg. There was a familiar sensation of a tightness in their sacks that quickly bloomed into an intense heat, more full nuts rapidly growing and increasing their already explosive cum output, one of the bystanders getting knocked over as they were blasted by a cumshot thicker than their thighs. Ember's taurish bodies couldn't help but thrust against their own cumflated bellies, making them wobble and loudly slosh from the movements, bringing them so much more pleasure that was hardly even needed with how great things felt already. The whole area smelled strongly of their musk from the sheer amount of cum they were pumping out, the treeline painted white and the ground covered in an inches-deep flood of semen, the mess continuing to grow larger and spread further, just like their bodies. They were already almost as tall as their house, and things were getting ever more intense.

All of their rumps shuddered before more pushed out from behind them, their bodies quickly growing longer and sprouting more legs, another group of genitalia, anuses, and tailmaws growing in while their bodies grew longer, making room for more legs, more junk, more tails.. Every one of their taur bodies gained several rows, each of those new rows having their own legs, sensitive bits that were already cumming hard, and drooling, hungry tailmaws, turning them into a mass of pleasure-drunk taur trains. They suddenly felt almost painfully empty, having so many new stomachs and wombs to fill, but that problem didn't last long. With all of their newly grown cocks, there was plenty for all of their tails to drink from, barely any of their dicks left untouched for long as their tailmaws lunged in, countless gallons of seed rapidly filling them up beyond capacity, bellies gurgling and sloshing as they were bloated out. The thoughts of trying to stop it slipped further and further away, Ember nearly losing their mind from the bliss of cumming so much, so endlessly.. luckily for them, there was still lots of space left for them to grow, another wall of their house being knocked down.

Hours passed, and not for a single second did the kitsune's orgasm stop or even slow down. They'd grown much larger, to put it lightly. They had long since grown larger than their house, which was now stuck under one of their thousands- if not millions- of bellies filled with lakes worth of cum, now far larger than even the city near their home, which was also stuck underneath them. Despite how many bodies they had, all pressing and rubbing together, their massive, countless tailmaws weren't deterred from drinking all they wanted. Whether it was chugging semen straight from their cocks, from their overflowing tailholes or mouths, or even drinking the rivers of milk that were pouring from the rows of mountainous tits down their fronts.

They had enough time to partly adjust to the pleasure, regaining some control of their bodies, but control of their mind was still far away. All of their bodies grew many more arms, all of them having hands with tongue-filled mouths, and they couldn't stop themselves from using those hands to suck, lick, and kiss themselves wherever they could reach. Everything as far as they could see was buried in an ocean of cum, milk, and pussy juice, spreading to every edge of the horizon. Their own body was covered too, cocks larger than buildings shooting their loads into the sky to rain back down all over themselves, providing no shortage of lubricant for them to be stuffed in every hole available.

The speed and intensity of their transformations had been increasing nonstop, to the point that new changes started while the previous were just getting started, things constantly moving and shifting to make space for new parts to form and for existing parts to grow further. Their exhausted, overstimulated, blissful mind could hardly form a single thought, but the one thought that went through their heads was hoping that they wouldn't regain control, that the transformations and growth would keep going and going without end. Fortunately, it seemed like their wish was going to become true, at least for a while- after all, that gemstone they swallowed, still deep in one of their stomachs, wasn't going anywhere anytime soon..
