The sun rose high above the peaks of the Horseshoe Mountains, bathing Equestria in the first orange rays of dawn. Roosters made their morning call, and across Equestria, alarm clocks rang out in a chorus of ringing, clattering, and otherwise obnoxious sounds, dragging millions of ponies out of bed to begin their day. Already, showers were hissing, toothbrushes running across flat herbivore teeth, and heaping piles of haycon sizzling away on frying pans.
For Twilight Sparkle, however, this wasn't the start of her day, not nearly. Her day – To the extent that it could technically be called a day – Began yesterday morning, when a crash resounded through the castle, so that the unicorn was pretty sure Tirek himself had crawled from Tartarus to exact his revenge. But no, it was just Derpy Hooves, that wall-eyed goofball, tossing a package clean through an upper-story window. Twilight was a charitable mare, but a daily mail route shouldn't involve so much property damage! Before she could storm down to the post office and complain, however, she caught sight of the label on the package, and with an excited squeal, she scooped it up and teleported to her laboratory, leaving Spike to sweep up the broken glass.
She'd been waiting for this one for weeks – Months! Ripping open the package and sifting through a layer of foam peanuts, she pulled out a ratty old paperback book, and let out a squee capable of giving Pinkie Pie a terminal case of diabetes. It looked like any old paperback, with a torn and stained front cover, and a spine cracked and wrinkled from countless years of reading, but to Twilight, it was the culmination of a grand search, for this was no mere pocketbook, no, far from it.
The book which she held in her hooves, parked safely on her favorite reading chair, was nothing less than a first edition copy of Von Junzt's Nameless Cults! Oh, how she'd searched for it – The publisher, Golden Goblin Press of Manehattan, specialized in mass market editions of obscure texts, mostly medieval alchemical works filled with enough half-truths to get a pony in some serious trouble should they actually attempt any of the potions or rituals contained within, but this one book stood above all the rest, with it's value matched only by it's rarity. Only a few hundred copies were ever printed before the publishing house was raided by the authorities, and nearly every copy was burned. There are some things, as the Cultfinder General said, that ponies were never meant to know – Some of which were contained within that very paperback volume.
Yet, despite the destruction, several copies survived, mostly review copies the royal guard couldn't track down. There were rumors of an editor at the press who managed to smuggle an entire box of copies out before the guards set the building to the torch, along with all inside, but that was probably just a story. The copy Twilight held had a plain black cover, with the title printed in simple font, and below that, the words [ADVANCE REVIEW COPY – NOT FOR RESALE].
But resold it was, through black markets which dealt in blacker magic than Nightmare Moon herself would dare cast. It cost a pretty bit to get ahold of, but by Celestia's beard, it was worth it! After a full day and night of reading, Twilight's eyes were red, her mind swimming with forbidden knowledge. Strange thoughts came into her mind unbidden, like alien thoughts transmitted to her brain, like the book itself was telling her things, important things her waking mind couldn't quite understand. She didn't know exactly what it was, but she was pretty sure those geometric shapes on the page were components of a spell, and that squiggly line along the side – An ancient runesnake, the scales forming patterns that were vaguely familiar to her eyes.
It took a bit of work, a little cross-referencing with other, even more obscure texts, whose pages threatened to crumble to dust were she to remove them from their magically-sealed containers, but at last, Twilight felt herself ready. Standing in the middle of her spell testing chamber, the door sealed, and most importantly of all, a cup of warm tea to rejuvenate herself afterwards.
A series of gemstones sat around her in a circle, each one carved with a different rune, and beyond that, an unbroken circle of salt, the incontestable standard for magical containment. Simple, but effective, no summoned creature could cross a line of salt. It wasn't like she was trying to summon Yog-Sothoth, just a minor demon, hardly more than an elemental, as a matter of fact. Ylanek-Drusch was the living embodiment of filth, decay, stench – His influence could be felt in every fruit left too long at the back of the fridge. Judging by the instructions in the book, he would be fairly easy to summon and dispel, just as a test – And should she make some mistake, either hers or on the part of the book's writer, she was confident in her ability to end the ritual safely. After all, she was Princess Twilight Sparkle!
Spreading her wings and raising her head high, Twilight chanted the words of the spell, her horn igniting with swirling bands of purple magic. As the chanting continued, the magic began to darken, first to black, then lightening somewhat, to a pale, sickly brown. It didn't seem to swirl anymore, so much as seethe around her horn like a pool of putrescent gas, and with a final shout, the cloud exploded forth from Twilight's horn, filling the space betwixt the runes, but staying well away from the salt circle.
As suddenly as it began, however, the spell ceased, leaving Twilight standing in the middle, panting. A sense of accomplishment burned in her chest, her heart pumping a thousand beats a minute. She glanced around feverishly, her sleep-deprived brain searching for the demonic presence she had just summoned. The room, however, appeared empty – Maybe the demon was invisible? Or maybe-
A long, low fart sputtered forth from Twilight's backside, filling the room with an eggy smell. Twilight groaned, disappointment mixing with disgust. The spell didn't work, at least not entirely. She was certain she felt the doorway open, but she couldn't be certain that anything had come through. Maybe it was just her imagination, maybe the spell was useless. Maybe it was a joke designed to humiliate ponies by making them fart – But more likely, that was the result of not eating for more than 18 hours.
Stepping out of the circle, she downed her tea and unsealed the door, heading outside. She needed food, coffee, and a shower, in that exact order. She didn't even notice the spot where her fart had blown the salt away, breaking the containment circle.
Galloping down the twisting dirt road that led to Sweet Apple Acres, Twilight cursed herself for not remembering her planned meeting with Applejack. It was... Maybe four hours into last night's vigil when Spike knocked on the door and told her Applejack needed help with some sort of problem, and could she please come by tomorrow, preferably before noon?
Thank Celestia for the note he slipped under the door, or she wouldn't have remembered until it was too late. The sun was already edging toward the middle of the sky, but if she was fast, she could still make it in time – She wasn't like Rarity, always striving to be 'fashionably late', she preferred to actually keep the appointments she made. There was no time for a shower, or even a snack, and so, as the vast apple orchard spread out before her, she tried to ignore the gnawing at the pit of her stomach, and the faint hint of musk rising up from her fur.
“Howdy, Twi!” The cowgirl stood at the gate to greet her. Despite her lateness, there wasn't a hint of irritation in Applejack's voice, her wide smile serving to calm Twilight's pounding heart as she slowed to a trot. The two headed across the farmyard, standing shoulder to shoulder as they chatted about whatever small things came to mind.
“So, what where you so busy with yesterday?” Applejack asked, “Spike said you got some sort of package and ran off.”
“Oh, it was a book,” Twilight rubbed the back of her neck self-consciously. As expected, Applejack seemed satisfied by that explanation and didn't press the subject, not that Twilight was going to explain the sensitive details of her delvings into dark magic to her honest friend. The smell of apples drifted across the farm from the orchard, and Twilight's stomach let out a low growl.
“Skipped breakfast, eh?” Applejack chuckled, to which Twilight nodded sheepishly.
Big Macintosh was out in the orchard, bucking trees and collecting the fallen apples in baskets. It never ceased to amaze Twilight how perfectly they always fell, not single one missing the basket, or even getting bruised in the drop. A dozen or so baskets were scattered around the nearby trees, waiting to be picked up, and with Applejack's nod, Twilight headed over and picked one out of the pile.
Twilight smiled as she gazed at the smooth red skin, so clean that she could see her distorted reflection in it. All it took was a quick spell to core and slice the apple into quarters, and with a smile, she took a bite. The moment the apple's succulent flesh hit her tongue, Twilight gagged and spat it out. Even though it was freshly picked, the apple tasted rotten, filling her mouth with a taste like she'd licked the end of a magical battery.
Groaning, she decided it was probably a cold. Too many all-nighters, too little sunlight and sleep, it was only natural her immune system would catch up sooner or later. It was a little bit funny, in the years since becoming an alicorn, she hadn't suffered so much as a sniffle. If anything, she figured, a brief bout of sore throat and stuffy nose would be a break from the normal routine, an excuse to laze around drinking hot tea all day... Not that she didn't do so already.
Still, she had to fill the pit in her stomach. Casting a spell to dull her sense of taste, Twilight choked down the apple slices and returned to Applejack, who thankfully didn't seem to have noticed her hesitation. The two continued on, heading towards the barn.
Tugging a bandana from her pocket, Applejack covered her nose. Twilight glanced at her curiously, but before she could ask why, they turned the corner and entered the barn. As soon as they cleared the doorway, a horrific stench met Twilight's nose, like a rotting carcass in a swamp. The alicorn took a step back, covering her nose with a hoof and swallowed hard to keep from retching.
“Sorry, sugarcube,” Applejack placed a soothing hoof around her friend's withers, “It didn't smell this bad when Ah checked it yesterday.”
A huge wooden barrel stood in the corner of the barn, twice as tall as Twilight and about as wide as she was long. The entire thing was coated in a black, tarry substance, leaking between the cracks in the boards. The metal rings holding it together were clearly rusted and falling apart in some places, letting little spouts of brownish fluid pour out and across the hay-covered floor. A rickety wooden platform kept the thing off the ground, but even as she watched, Twilight could see the supports swaying from side to side, the rusty old nails threatening to snap and send the whole thing tumbling down.
“It's th' manure tank,” Applejack explained, her voice muffled beneath her bandana, “Th' poor thing took a beating during the storm last week, an' now it's fit to burst. Ah've ordered parts to make a new one, but Ah was hopin' y'all could fix it up, or at least cast some sorta spell t' keep it from breaking in th' meantime.”
Applejack grimaced as her hoof accidentally touched the shit-soaked hay, which spread around the tank in a wide circle. For some reason, Twilight didn’t feel the same visceral reaction as she stepped forward and felt the wet hay squish beneath her hooves. Intellectually, she knew she was stepping on the collective droppings of a whole herd of cattle, but her stomach remained as stoic as ever - If anything, she was still a little bit hungry.
Applejack looked at her strangely, unsure whether Twilight was messing with her, or just being stoic. The orange mare took a step forward, unable to conceal her disgust as the filth soaked into the bottoms of her hooves.
“Whaddya think?” She croaked, barely holding back a retch.
“I…” Twilight began, only to pause as her stomach let out a fierce growl. For some reason, she couldn’t keep her eyes off the dripping, leaking septic tank.
“Ah'll leave ya to it,” Applejack's hooves splashed wetly on the inundated hay floor, “Ah'm sure Mac needs mah help wit' somethin'...”
The cowgirl's hoofsteps soon disappeared, leaving Twilight alone with the septic tank. Taking another step closer, Twilight inspected the thing for damage. Applejack had said it was damaged in a storm, but the thing was clearly in poor repair before that. The boards were rotten, the iron bands were rusty, and all that was left of the nails holding the hulk together were little nubs of oxidized metal. The thing creaked faintly, the boards shifting back and forth as shit-slurry oozed out between them.
It looked like the job for a carpenter rather than a magician, but Twilight could think of a few ways to deal with it. A simple magical grip would hold the boards together, and a sealing cantrip – A sort of magical glue – Would hold them together tighter than when the tank was new. Cleaning up the floor would be a disgusting business, since she'd have to teleport all that shit-soaked hay outside and burn it, but a spell to deaden her nostrils would help with the smell.
Twilight paused, then nearly facehoofed – Nearly, because doing so would mean rubbing her filthy hoof on her face. Why didn't she just cast that spell when she came in? And for that matter, why did she walk on the shit-soaked hay? The puddle of sludge only covered about a quarter of the barn's floor, and beyond that was clean hay. None of her spells required her to get close, so why..? It was almost as if she wanted to get up close to that foul thing, to get a good look at the rotting boards, the weeks-old shit leaking through the cracks... At the botton, there was a little spigot. It wasn't very big, no longer than a pencil, and with an opening hardly wide enough to fit a cork in. It was as rusty as the rest, and had probably been added back before this enormous barrel was repurposed as a shit-tank. In a past life, it was probably a cider barrel, capable of holding hundreds of bottles worth of the good stuff. Now, all that leaked from the spigot was a slow, steady drip of brown fluid.
It was a truly horrific scene, yet somehow, Twilight couldn't take her eyes off it. Her stomach growled, even louder than before, and she groaned, trying to ignore the nagging hunger. She needed something to eat, but instead of thinking of Granny Smith's homemade pie, her thoughts kept drifting back to the manure tank. Taking a step forward, she crouched down, and without realizing what she was doing, lapped up a droplet of sludge leaking from the spigot. A foul, acidic taste filled her mouth, and she staggered back, horror and disgust filling her chest as she realized what she had done.
“W-why the horseapples did I just..?” Her words trailed off as she swished the shit around in her mouth as if it were a choice morsel, her tastebuds burning from the revolting taste. It took her half a second to realize she'd swallowed it, and when she did, disgust and revulsion rose up from her belly. She wanted to puke, but her body refused, the muscles refusing to move. It was... Intellectual. She knew it was bad, but for some reason, that sample was enough to get her stomach really churning, her tastebuds demanding more.
This is what ponies mean when they talk about acquired tastes, she realized, returning to the spigot. The handle was rusty, but a little lubrication spell got it turning, and the flow increased from droplets of liquid shit to a steady stream of thicker sludge. Lowering her head, she took a gulp from the flow as a foal would gulp ice cream from a mixer, and shivered as the revolting flavor filled her mouth. Why couldn't she have acquired a taste for wine, or cigars, or even marmite? This stuff tasted bad, but it felt good – Though her tastebuds curled up in disgust, it gave the same pleasant feeling as she normally got from a fresh apple, or one of Pinkie's cupcakes.
Her brain felt odd, a bit of fog clinging around the corners – It had been there all day, a result of her overnight study, but it hadn't become apparent until now. Her thoughts were moving a bit slower, and strange ideas came unbidden to mind – Her eyes focused on the stream from the tap, and suddenly, the alicorn's better judgement was overwhelmed by the urge to drink. Without a moment's hesitation, Twilight leaned down and wrapped her lips around the rusty faucet, the metallic taste filling her mouth for just a moment, before the stream of shitwater flowed into her mouth.
Twilight moaned, her eyes rolling back as the heavenly sensation overtook her. It didn't even taste so bad, now that she had a constant supply of it, her tongue lapped happily in the filthy stream, letting the cold liquid ooze down her throat. Once in a while, small chunks of undigested plant matter came into her mouth, which she chewed and swallowed as easily as one chews a chunk of carrot in a soup.
The shit was cold as it ran down her throat, but with every mouthful, her stomach began to feel warm. It wasn't unpleasant, certainly no worse than the taste of the cow shit she was guzzling; In fact, it felt kind of good, and the alicorn found herself squirming as the warmth spread throughout her body, running down her legs and up to the very tip of her horn, where a little spiral of magic began to glow. It wasn't the usual purple color, however – This magic was murky, like a light shining through muddy water. She didn't notice the color, nor did she notice the growing tightness in her midsection until it was too late.
Her small paunch, the result of a lifetime of sedentary reading, crept outward, with every gulp adding to the inordinate volume of filth. It was packed tight, sending little twinges of pain across the surface of her stretching skin. A gurgle rose up from her gut, a low, sickening grumble of distended flesh and overworked juices, and in Twilight's increasingly addled mind, only one thing made sense. She wasn't going to stop her meal, not while this hunger still gnawed at the back of her mind, and the strange noises and feelings only amplified this feeling. She must be hungrier than she thought; That's what ran through her head as she illuminated her horn, the murky magic turning into a full glow as she cast a spell on her stomach.
The flesh seemed to ripple, then, with a curiously wet GLOOP, it sagged down, turning countless pounds of compacted fecal matter into a soft, sagging potbelly. The instant digestion spell was simple and effective, and as Twilight continued to drink, so too did every last disgusting gulp turn into lard, clinging to her belly, her flanks, her cheeks and chins, until she looked almost as chubby as she had upon her first visit to Ponyville. Her thighs nearly touched, an extra fold of fat peeking out beneath her chin. It felt good; The warmth didn't abate across her body, instead growing more intense as time went on, pounds slowly piling onto her body as she continued her drink.
Foul, brownish sweat leaked from every pore, leaving dark streaks in her fur as they raced to the lowest point of her belly before dropping down into the mucky hay below. Her fur became limp and scruffy, slicked down by rivulets of filthy grease, which quickly spread across her torso, turning her into a veritable waterfall of diarrhea juice. It didn't take long for her fur to start falling out, individual strands at first, carried away by the stream; Then, larger clumps began detaching, leaving behind gaping pores oozing nothing but brown fluid.
The alicorn's skin seemed to wrinkle, deep cracks running across her body as her skin darkened, going from a pale pink to a murky brown, not unlike the mucky hay beneath her hooves. Piss erupted from her slit, running down her leg in a warm stream. The yellow soon darkened, however, turning the color of incredible dehydration, then to a sickly bile brown. It felt good, like the slow, continuous buildup to an orgasm, every moment increasing the heat and pressure in her loins. Twilight flinched as she came, adding a momentary burst of white droplets into the brown stream
Twilight looked down at her hooves, staring without comprehension as the last fur shed from around her ankles, falling like purple snowflakes across a muddy field. She brought her mouth away from the pipe for just a second, shit dribbling from between her lips as she raised one of her legs and stared at the flat brown stump – Her hoof was still sitting on the floor, she realized, just a useless chunk of keratin. She could stand perfectly fine without them on legs that were – She realized with a sense of dull alarm – Made of shit.
You are what you eat, as they say.
She could feel the corruption seeping into her mind, taking hold on her thoughts, yet she didn't feel the slightest bit of concern – She knew this wasn't right, she was a mare, not a pile of living fecal matter, but somehow, it just felt... Good. Her legs felt numb as the shitflesh snaked up them, her bloated belly aching from the strain of all the filth gurgling away within.
Female juices ran from her pussy, saliva oozing from her mouth as pleasure wracked her body. This transformation... She knew it was doing things to her, that something was very, very wrong, deep down in her soul, but she could do nothing but enjoy it. For some reason, the loss of her very ponyhood didn't frighten her nearly as much as the thought of running out of shit to drink, which came suddenly as a wad of congealed filth clogged the spigot, bringing an end to her sordid meal, at least for the moment.
There was a soft sloshing sound as Twilight backed away from the manure tank, her shitty body wobbling like chocolate jello. Her mouth felt strange, her teeth tingling uncomfortably, and after wiggling one with her tongue, she was surprised to feel it simply fall out of the socket. Spitting it out, a half dozen more came out with it, knocking her famous smile across the floor. It didn't matter – New teeth were growing in, big, sharp ones made from something that wasn't quite shit and wasn't quite enamel. She were strong, though – She felt her jaw stretching to accommodate them, elongating with an uncomfortable crinkling sound.
Twilight groaned as her pussy stretched open wide, and something huge and thick forced its way out. At first, it felt almost like she was being speared by a giant cock, but that clearly wasn't the case – It was too wet, too pliant, easily giving way as her pussy lips instinctively squeezed around it. No, it wasn't a cock – It was a turd, a giant, wrinkled piece of shit forcing itself free of her vaginal lips, but the feeling as it scraped against her clit, covering the fleshy nub in brown waste, was all too sexual. The alicorn moaned, gritting her teeth and trying to push it out, but it just didn't end, growing longer and longer past the point where a normal turd would've broken off.
Then turd began to move on its own, almost moving in time with Twilight's grunts and moans. It wasn't just a turd, but a tentacle made of solid shit, protruding from Twilight's now-filthy pussy like a giant futa cock! The alicorn's eyes rolled back as her new appendage swayed from side to side, almost tasting the air around it, and finding it sufficiently filthy, it's brother sprouted out of Twilight's purple princess pucker, distending her hole so far that she was sure it would rip, sending bolts of a feeling that should've been pain, but in her muddled and lusty brain, felt more like pleasure.
Twilight gazed over her shoulder, a wide, shit-smeared grin on her face as she waved both of her reeking tendrils through the air. They were made of pure cow manure, same as the rest of her body, and the stink coming off them was almost tangible. She inhaled deeply and sighed at the utter shitstench, though it was really just the smell of her own fecal flesh.
The stench now filling the barn was even thicker than the previous, foul odor of the manure tank. As the poisoned air drifted out the front door and through cracks in the walls, the lush grass surrounding the barn turned a sickly shade of brown, each blade curling up and crumbling to dust as soon as a faint breeze happened to blow across the farm. Soon, the barn was surrounded by a circle of barren earth, so toxic that nothing would grow there for centuries.
There were more immediate effects, as well. The sheer potency of her new stench would've been enough to overwhelm a mere pony, eating into their skin and burning them from the inside out; Here in the dilapidated barn, the wood began to rot at an increased rate. A stack of old crates in the corner creaked, then crumbled to splinters, and beneath her very hooves, the hay floor dissolved into a mushy mass of mud. Twilight grinned, splashing happily in the filth, rubbing it all across her distended, mutant body. It was only too late that she looked up to the manure tank, but she didn't panic – She opened her mouth, baring her new filth-fangs in a grotesque approximation of a smile.
The wooden tank creaked as the boards began to decay at a rapid pace, the rusted nails dissolving into chunks of oxidized dust and crumbling apart. The iron bands strained against their failing structure, but they couldn't last long, and before long, the entire thing burst apart at once, as if someone had stuffed a grenade in the rotten barrel. A tidal wave of liquid shit flowed out, and Twilight opened her mouth wide to receive whatever she could. Even as her mouth filled up, shit flowing down her throat, the rest of the shit seemed to congeal around her body, clinging to her scatty flesh, melding together. Her newfound obesity vanished as all bodily structure disappeared, turning the mare into little more than a head poking out of a massive pile of shit.
Twilight grunted, straining her neck as she tried to move limbs which simply no longer existed. Part of the shitpile wobbled as she did so, and she realized – She could feel the entire floor beneath herself, as if it were all a part of her body. A strange sensation rose in the area which was once her chest as she realized that no, she hasn't stuck – She had all the mobility in the world.
Her horn glowed, and the glow spread across the blob of living manure, illuminating the polluted barn in a sickly glow. The surface of her body wobbled and quivered like jelly, contracting in some areas, expanding in others. Logs of shit sprouted from some spots, growing long and slender – Tendrils of pure waste, waving around in the warm, filthy air. The thing-once-known-as-Twilight bore a faint resemblance to a giant sea anemone, especially as more tentacles erupted across the former mare's belly and back.
Twilight stared down at her body, at the utter loss of her equinity. The brown mass extended in all directions, studded with those slender, slippery tendrils. She was hideous, an abomination by any standard, but at the same time... She was beautiful. She was so smooth, covered in little dimples and cracks in the ever-shifting shitscape of her body. When she thought about it, tentacles were really a lot better than hooves. Meat and bone were weak, but shit was strong, capable of holding her entire multi-ton body aloft with ease, not to mention, she no longer needed to wear horseshoes.
She couldn't keep this blessing to herself, however – She needed to share it with her friends! With everypony in Equestria! They might be reluctant to give up their bodies at first, but once they understood the beauty and power of their new shitforms, they'd be perfectly willing to join Twilight in her new state.
But first, she'd need to gather her strength. Transforming into a superior lifeform takes a lot out of a mare, and even with her meal, Twilight could feel a gnawing hunger growing at the pit of... Well, not her belly; It was a collective feeling, felt throughout her entire body at once, almost overpowering her mind with the sheer force.
Using her lower appendages – For they could no longer be described as limbs – She raised her body up from the floor, shit dripping from the underside of her slick flesh, and slowly wriggled along on the tips of her tentacles until she was close enough to the broken tank to plunge her tentacles into the scummy dregs clinging to the bottom of the barrel.
Her horn began to glow, casting a brownish light across the barn as the shit-soaked floor began to dry up, the filth flowing across the hay like a retreating tide as her body absorbed it. There was a wet, low sucking sound, and Twilight's face, still almost untouched save for being made of pure horseshit, twisted into an approximation of a pleased grin, like she'd just eaten the best meal of her life. As she sucked up the last of the slurry, the shitbeast let out a deep, gurgling cry.
-=-=-=-
“... What in th' Sam Hill was that?” Applejack muttered as the sound slowly died away. The red stallion didn't respond for a moment, his hooves slamming into the trunk of a tree and sending a rain of apples into the nearby baskets.
When Applejack left Twilight in the barn, she figured the alicorn would take a few minutes to cast whatever spell she needed, then come back to help in the fields; But according to Applejack's reckoning, she'd been away for the better part of an hour. Between the two of them, the southern field was almost completely harvested, and they'd need Twilight's help to get all those baskets of apples into the storage shed before nightfall.
“Prob'ly magic,” Mac said simply, shrugging, “Best get back to work.”
Applejack shook her head. Something about that noise just didn't sit right with her – When the sound came over her, she couldn't just hear it, she could feel it, a kind of rumbling in her gut as if she'd eaten something bad. Her bowels felt warm and heavy, and she grunted as a sickly-smelling fart hissed out of her plump pucker. The end of the fart tapered off with a wet burble, causing her to grimace; She could feel the pressure against her anus, not incredibly strong, but it was there. She managed to pinch herself shut before anything could come out, but Mac seemed to be feeling differently.
The red stallion was standing next to the tree, priming himself to give it a solid buck... Only to groan as a sickly gurgle rose up from his midsection. Placing a hoof on his belly, he grimaced, and Applejack thought she could see something shifting beneath the skin. The stallion looked oddly bloated, and judging by his expression, he felt it, too.
“Gotta go,” Mac grunted, and let out a long, low fart. The stallion's expression changed from one of constipation to panic as he felt his pucker stretch open, and before Applejack could turn away, a fat turd forced its way out of the stallion's backside. Mac's face turned redder than ever, and without a word, he turned and waddle-ran away, his hooves clumsy as he tried to hold back a tide of diarrhea.
Applejack gagged and averted her eyes from her brother's accident. What in Celestia's name could've brought that on? Then, another noise resounded from the direction of the farm, and the apple mare grunted as a sickening gurgle ran through her bowels. After making a quick – And rather violent – Stop in the outhouse, Applejack approached the barn. At first, she thought the smell was just the dung heap beneath the outhouse, but it grew stronger the nearer she approached the farm's main buildings.
The smell was coming from inside the barn, she realized as the immense structure came into sight. It wafted through the open doors, the hayloft and the boarded up windows. Applejack paused, staring at it for a moment. The barn looked dilapidated, like it hadn't been maintained in years. The barn leaned slightly to one side, the roof buckling in the middle as if worn down by the weight of a hundred heavy winters. The paint was faded and peeling, even though they'd just repainted the thing during the Apple Family reunion just a few weeks prior.
As she drew closer, a brownish miasma seemed to form in the air around her. She didn't realize it was there until the entire world bore the tint, like her eyes were coated in mud. They did sting slightly, but it was nothing compared to her nostrils, which wrinkled involuntarily at the stench. She could just about feel the hairs in her nose curling up and sizzling away, one by one, as the shitstench blew down her throat. It was worse than shit, worse than the old manure tank after weeks of stewing in the heat; The orange mare choked down a mouthful of bile before it could reach her lips, forcing herself to move forward, even as the grass changed from green and healthy to brown, and eventually to an expanse of barren dirt surrounding the barn in a near-perfect circle.
For a moment, Applejack considered turning around and getting Mac, and maybe even calling for help. Whatever was happening in that barn, that had caused such a strange transmutation of the otherwise normal farm, it could be nothing short of unholy.
And Twilight was in the center of it.
No matter what was going on, whether some unhallowed monstrosity had crawled from Discord's netherworld, or some new threat had arisen to threaten Ponyville, she wasn't going to leave her friend to deal with it. They'd defended Equestria together, Twilight had saved her life more times than she could count, and now, it was her turn to do the same. Steeling herself – And plugging her nose as tightly as possible – Applejack turned the corner and stepped into the corrupted barn.
“What in Celestia's name is goin' on here?!”
In the center of the barn stood a massive pile of dirt, shifting and billowing like a muddy bubble in a hot spring. The surface undulated vigorously, rising and falling, quivering like jello, but never breaking or even so much as cracking beneath the constant motion. The thing was covered in small, wrinkled pores, and every few moments, one of them would open up and spew forth a blast of foul miasma, adding to the weight of corruption which lingered in the air. The moment the apple mare stepped in, thick, meaty tentacles sprouted across the wobbling surface, and as they drew closer to the mare, the tips opened to reveal milky white eyes, each one the size of her own.
A faint hint of recognition was visible in those eyes, causing a shiver to run down the mare's spine. The many eyes appeared to be blind, with pupils so dull that they blended with the whites, but as the tendrils arced down toward her, it was apparent that the creature was studying her with something approaching curiosity.
Applejack took a step back as the 'flesh' of the thing began to bulge, and from it emerged the outline of a pony's head, formed of brown, slimy shitmeat. Sludge oozed off of it in waves as the features slowly coalesced, a muzzle stretching out of the primordial mud, a pair of ears, a bump on the top that slowly elongated to something similar to a unicorn's horn. As the head emerged, Applejack retreated, her head feeling so light that she may as well have been walking on air. Disparate, useless thoughts drifted around the corners of her mind, completely random ideas and concepts dredged up by a brain that wouldn't – Couldn't – Accept the existence of the horror standing before her. The shithead's eyes peeled open, revealing a pair of vaguely purplish orbs.
“T-Twahlaht?” Applejack stammered. Her hoof touched something soft and slippery, causing her to slam down hard on her haunches. When she looked down, she realized with some slight surprise that she'd shit herself without realizing it, from fear and surprise and the constant, infernal churning of her bowels – But such a thing hardly seemed important at this very moment.
Applejack was a simple mare. She worked hard for her family and her friends, and they supported her in turn. She wasn't much for book-learning, and impossible stories did little more than rankle her nerves. She could never understand the urge that drove some ponies to bury their noses in books about things that never happened, and could never happen, not when there was still work to be done.
She never paid any attention to things that didn't concern her. That the universe existed, she could accept, and that the sun lit the world and the moon ushered in the night, were simple facts that affected her everyday life. That the universe was constructed from tiny specks of dust known as atoms, was an obscure concept at best, and when Twilight tried to explain the correlation between the sun and the stars, she found it so utterly absurd that she couldn't help but laugh in her friend's face. As far as she was concerned, the old earth pony legends were right, about the stars being holes in the fabric of the sky, and the sun being the very body of an ancient fire goddess. As far as she was concerned, if it sounded ridiculous, it wasn't true.
Now, staring at the face of her best friend, made of pure feces and jutting out from a mountain of pure equine scat, surrounded by a million little beady eyes and gas-spewing anuses... To say she didn't know what to think was an understatement, and for a good, long moment, her brain simply shut down, refusing to process the information it had been given.
Twilight Sparkle was many things, a nerd, a weirdo, a freak with excessive magical powers – But most importantly, she was a friend, and Applejack never deserted her friends. But she'd never been in a situation like this before, and while her first urge was to turn tail and flee and run until blood ran from her hooves, she remained. Her second instinct was to grab a firestarter from the farmhouse and turn the barn into a funeral pyre, to blast this abomination from the very face of Equestria. Before she could make her decision one way or another, however, the creature opens its mouth, revealing a set of goopy brown teeth.
“Abbulgag?” The beast formerly known as Twilight Sparkle boomed out – She sounded like she was speaking underwater, modulated by a handful of wet towels. It was familiarity alone that allowed Applejack to vaguely understand her friend's voice.
“W-what happened to you?” The orange mare's voice sounded tiny and hollow as she squeaked out the only words that came to mind.
“I'b asgended, Abblelbag,” The freak gargled through a torrent of verbal diarrhea, “Dishish de shuperior form of life.”
Well, that was clearly a lie. Applejack's nose was beginning to actually ache from being scrunched up, and she forced it to straighten out, which unfortunately left her open to a lungful of the putrescent stench that hung around the beast. Her lunch splattered to the ground before her in a cascade of greens and browns, and before the torrent had run it's course, Twilight's tentacles were all over it, slurping it up through small openings that looked a little bit like mouths. The expression on the mare's face was one of utter ecstasy.
Applejack scrambled backwards, her hooves sinking into the muddy floor – It had been completely dry a few minutes ago, but now, it was as muddy as the bottom of a pig pen, but this didn't smell like mud. The mare yelped as something warm and wet prodded against her pussy, and before she could escape, Twilight's tentacle plunged between the folds of her marehood.
Applejack moaned, pleasure and agony mingling as Twilight's tentacle spread her pussy to the limit. She felt full, like she'd just eaten a full meal and kept going after her stomach was full, but it was just the sheer volume of the former alicorn's shit now filling her intestines. Her pussy was stretched to the limit, just about ready to shred apart, the tender flesh held together only by a shred of muscle and a bit of earth pony magic.
Applejack shut her mouth, and the tentacle bashed against her lips, covering them in shitslime as it struggled to get in. Her stomach churned from the stench, but she managed to hold back her vomit if only to keep her mouth shut. Her jaw wouldn't move, even her lips remained perfectly still as liquid feces smeared across them.
Her resistance didn't last long. Giving up on her lips, the tentacle pulled away, giving Applejack just a moment of hope before it slammed back down on her nose. Shit flowed up her nostrils, flooding her sinuses and blocking her breathing. She instinctively inhaled, sending a torrent of acrid liquid down her throat, and that was it for her resistance.
Applejack opened her mouth to puke, and as frothy slime splattered the ground at her hooves, another tentacle slipped between her jaws and down her throat, flooding her stomach and piercing the opening to her burning lungs. She tried to bite down, but the surface was too tough for her teeth to crack through. A sickening gurgle rose up from her belly, but it wasn't her own; The tip of the tentacle opened up like a mouth, vomiting forth a torrent of hot, reeking fluid.
Her stomach filled up in an instant. Her overfilled sinuses pounded from the pressure, she could feel the tendrils working their way through her head. Something warm wrapped itself around her brain, poking and prodding various places, sending forth bolts of pain that blanked her mind and buckled her knees. The tentacles were strong enough to keep her from falling, and so she remained suspended as the filth overtook her body.
Her mind reeled, trying to fight off the unrelenting assault. She had a sturdy and simple mind, which might've protected her to an extent – Her honestly and loyalty served to shield her against the poking and prodding tendrils. Focusing on her friends and family, those she cared about, whom she would never betray, she managed to cling to herself, to stand like a rock amid a tide of pure diarrhea.
“Shdob fibghdin,” The thing that was Twilight gurgled, brown foam oozing from her thousand mouths. The sensation of pumping her friend was one of pure pleasure, like a long, continuous orgasm from multiple cocks. She could feel her friend's pussy winking, her anus clenching futilely around her thick turdsnake, while her throat clenched and vibrated, squeezing her shitlog in a way that make the 'mare's synapses light up with ecstasy.
She could see and feel everything, every last inch of her body lighting up with sensations as she pumped more and more of her filth into Applejack's puny body. She didn't want to hurt her friend, just help her, and sometimes, you had to be cruel to be kind. She could hardly believe she used to be like that, a creature of flesh and bone, weak and easily broken, and nearly impossible to repair. Ponies were fragile and far too clean – The only truly worthwhile part of them was that clever contraption called a gut, which processed foul things like food and fruit into excrement.
To think that she once flushed her shit down the toilet... It sent pangs of rage and disgust through the shitbeast's gut. So much good food, so much beauty, wasted by a creature who simply didn't understand it's worth. It was like watching someone throw a diamond ring in the trash, thinking it was only glass. It wouldn't happen again, she could be sure of that. She would cure Equestria, clean it of all these living shit-factories and turn them into thralls, transmuting their bodies to a finer, fouler substance than mere meat. It wasn't hatred or malice that drove her to think this way, but her old personality, still present despite the lack of anything that could be described as a brain. Twilight Sparkle, Princess of Magic, was going to grant Equestria the greatest gift of all – Starting with Applejack.
The mare was fighting, but she was swiftly losing ground to the onslaught. Her belly was the size of a beach ball, filled with so much excrement that her taut flesh was visible through her thinning fur. Her hooves no longer thrashed, but twitched uselessly in midair, and her eyelids were slowly closing over a pair of dull green spheres. Her eyes no longer bore the aspect of an intelligent creature, but that of a dumb animal. All her mental energy was focused on maintaining a foothold in her own mind, and she was swiftly losing control.
She just had to hold on, to wait for somepony to come looking. Mac would surely come looking for her, or Applebloom... Her stomach gurgled with hunger. Applebloom was a delicious morsel, a tasty little bundle of crunchy bone and soft flesh with which to feed her ever-growing body. Wait, no! Her eyes shot open, and she thrashed in her prison, but as the tentacles up her pussy and ass expanded, pleasure and pain tore through her body, causing her resistance to falter once more. She wouldn't – She couldn't falter, couldn't betray her family! She'd be dooming them, and possibly the entire pony race to a fate worse than death!
But with every thrust of Twilight's tendrils, pleasure shot through her loins as if it were a handsome stallion, instead of logs of pure shit. All Apple mares were prime breeding stock, with wide hips and wombs capable of containing countless young. Applejack was no exception, but even so, her hips strained around the stiff turds plunging in and out of her holes, the bones themselves struggling to hold together in the wake of such a violent fucking. Her womb was the size of a beach ball, straining against her flesh; Her belly was practically split into two conjoined spheres, her shit-packed belly in front, and her overloaded womb pressing against her hind legs.
Slowly, too slowly for the mare to notice, her body was being corrupted. Whereas Twilight was aware of her own transformation, and found herself enjoying it, Applejack's dimming brain felt nothing but animal pleasure as her insides slowly melted together. The lining of her intestines sizzled away, her stomach and womb, both creaking spheres pressing against one another, fused into a single mass. Even her holes began to stretch, moving closer together until they fused into a single massive slit, allowing the rapetentacles to merge into one. It wasn't rape anymore, but as consensual as sex between grown mares could be. Applejack's mind flowed into Twilight, Twilight's mind flowed into Applejack, and together, they became something that had never existed before.
But it felt so good, and she was getting so hungry... Slowly, the tentacle in her mouth retracted, allowing the mare to gulp down a breath of air – Only for her to realize that she didn't need it anymore. Her insides weren't there anymore – All that was left of Applejack was a thin layer of skin coating a mound of living shit. She could feel her new body shifting and sloshing beneath the surface, bulging in some places, retracting in others – She needed to learn to control her new body, lest she tear through her disguise. Even now, splotches of brown were spreading across her fur, giving her coat the appearance of a half-rotten orange. She was hideous – and she was beautiful. Applejack stared down at her hooves, watching as the filth boiled away beneath the surface, and wondered why she ever tried to fight in the first place.
“Because you were weak,” Twilight's voice cut through her head, silencing her thoughts so utterly that, for a moment, the being known as Applejack practically ceased to exist.
“I was weak too. I learned the truth, and now, so have you.” Twilight didn't speak these words – Indeed, the protrusion of her head had melted back into the amorphous mass of living shitflesh – But they echoed in Applejack's brain, and she couldn't so much as raise a hint of doubt about them. She, for all her muscle, all her loyalty and honesty, was an utter weakling compared with Twilight. She wasn't just a friend – She was nothing short of a goddess, destined to rule Equestria beneath a sea of shivering slime!
But where to go next? Applejack was too subservient, any attempt at thinking such thoughts on her own was quickly silenced by a mental blockage, caused by Twilight's utter psychic domination of her mind. It was a hivemind, perhaps, but there were only two members. That would have to change soon, Twilight stated, and Applejack agreed with her own silence.
“A-AJ? Y'all in here?” A shrill, feminine voice called from outside, followed by a fit of coughing. Somewhere in the back of Applejack's mind, the word 'Applebloom' burbled up to the surface, though there was no association for what it could mean. That was fine – Twilight knew. Twilight knew everything.
“Applejack,” Equestria's new goddess of filth spoke, her words cutting through the new shitbeast's mind, “Consume them. All of them.”
