Chapter 1

Shadowy machinery, lattices of girders and support beams, innumerable pipes and containers. This is what greeted Saddle Rager as she awoke. She slowly blinked, her inherent grogginess dulling her initial reaction as she took in the sights, a small part of her believing that she was still dreaming. And yet, as she found herself growing more and more lucid, other sensations came to her. The slight chill of cool night air, a swell scent in the air, and the loud snores she could hear to her side.

Pivoting to the sound, she felt resistance. Glancing down, her eyes widened in shock. Instead of being clothed in her normal nightwear, she instead found herself clad in her hero outfit, the turquoise material that clad her diminutive form undeniable, as were the belt and mask wrapped around herself, cute butterflies and all. Second, she noted that her arms and legs had thick manacles binding them, only allowing her to twist the limbs ever so slightly. Checking around herself, she could see that she’d been tied to a chair. It was very big, her arms pulled out wide to lie upon the provided armrests. By the looks of things, at least two more ponies could sit on either side, and still have ample space to sit.

Her ponderings were ended by another loud snore. Managing to turn herself in her seat, Saddle spotted a very familiar mare in the same position as her. The pink skin, the swept back bubble gum mane, the white and purple striped costume. It was none other than Fili-Second, blissfully sleeping away in her seat. “P...pinkie… I mean… Fili… Filiiii…” Saddle whispered as loud as she dared.

“No… give me five minutes more…” A mumble drifted across, Saddle rolling her eyes as she took a deep breath.

“You need to get up please… if you would like to, that is…” She meekly replied, trying once more to get her arms free to no avail, grunting and puffing as she tugged against them. Oddly enough, whilst they didn’t break, she could feel them stretching and pulling, almost like they were made of some sort of metallic rubber. Still, she fought on, hoping that she could find some inkling of aggression to activate her powers. Before she could come up with something more, she noticed a strange sound. Something akin to flowing liquid, accompanied by deep squelching.

“Ah ha… I see that at least one of you is awake… that should be enough to get this party started.” A smooth, feminine voice announced from somewhere Saddle couldn’t quite see. Suddenly, the darkness of the room fled. A bank of aged fluorescent light bulbs illuminated the room in a dull glow, the sudden change causing Saddle to flinch back, blinking spots out of her eyes.

“Huh… wuzzapanning… a party?” Fili moaned out, her deep blue eyes unveiled as she finally came back to lucidity. Saddle felt her chair move, internal motors causing it to lean further forwards, bringing the two out of their reclined position. As the two were seated upright, the same strange noise returned, coming from somewhere above them. Confused, Saddle looked up the best she could, seeing nothing on the gantry above.

“Umm… who… whoever you are… show yourself… if you wouldn’t mind that is…”

“Somepony certainly know their manners. I’d be more than happy to… show myself… he he he!” The sloshing, bubbling noise came back in force, instead coming from the floor in front of them. Saddle was just about to ask again, pausing as she opened her mouth. From a set of grates, she watched as… something began to push its way up through them. A pink-purple mass oozed up, growing from a basketball-sized mound into a misshapen blob a little taller than the average mare.

Once it had reached full size, the two heroes could see details forming: first a pair of arms and legs, then a torso. Soon, a head formed onto, as a long, goopy mane and tail took shape. What was most striking about the creature, aside from its amorphous nature, was the fact that it was looking incredibly fat. Indeed, its legs were wide, bubbling out into a pair of round ass cheeks. A thick, round belly pushed out in front, a deep belly button in the middle as it sagged down past the creature's legs. Upon the chest, a pair of round breasts swelled up, the ponderous orbs sagging down onto the upper belly area, sloshing around as the creature jostled this way and that. A few additional swells of goo rounded out the creature's arms and face, creating a form which could charitably be referred to as obese.

“Surprised? Don’t worry, most ponies are when they first see me… it's the breasts isn’t it? Very full, are they not?” She joked, swaying herself and letting them jiggle about.

“Who are you, what are you, and what do you want with us… oh, and why does this place smell sooooo good?” Fili piped up, drawing a deep grin from the creature.

“So many questions, Fili. I’ll be happy to answer them. I’ll be honest, I’ve never really been one for names. The only name somepony else gave me was a serial number, after all. You, however, may refer to me as Mistress Malleable!” She shouted out, slowly walking over to Fili. “As for what I am… I suppose ‘failed experiment’ ought to suffice. An amalgamation of an artificial slime and pony DNA created what you see before you…” She leaned over Fili, a few stray droplets of goo dripping onto Fili’s costume. A predatory slime flashed across the creature's face, just mere inches from Fili’s own.

“As for what I want… well, I need some ponies for a little… experiment I’m running, shall we say. A fun experiment… don’t you like fun?”

“Yeah, I love fun! Aside from the whole kidnapping us in the middle of the night and tying us to comfy chairs, you seem like a really fun pony!” Fili blurted out, Saddle rolling her eyes in annoyance.

“Oh yes, you two are going to be in for a whole world of fun tonight… as the culmination of my final plan for this city! For it to come to fruition, it’s taken me many, many months to work my way up, getting together all the equipment I needed. That sweet smell? That sweet, delicious smell? Why, it’s all coming from my factory, my candy factory, supplying much of the nation's candy.”

“Wait… you own Dreamburies? Oh my gosh, I always thought it was weird that the new owner never showed themselves in public…” Fili pondered, watching as Mistress Malleable waddled over to Saddle.

“Indeed, and as I said, the pair of you are going to taste test my latest product.” Reaching her goopy arm out, she pressed a button on a small console positioned between the chairs. A low humming sound could be heard, and the two heroes glanced up to see a pair of hoses descend from above. They dangled close to their faces, the sweet smell intensifying as it swayed past their noses.

“Uuhh… so what is the plan here? If you needed testers, surely you could have asked somepony on the street?” Saddle asked meekly, her eyes fixated upon the tube as it moved about like a pendulum.

“Ah… so you did notice that? Well, let's just say I’m not exactly a creature with a good heart… well I don’t actually have a heart.” She paused, tapping a few more buttons, several electronic and mechanical noises starting up. “You see, ever since I was created, I’ve always enjoyed growth. And no, not in an economic sense… more so in terms of weight gain. Fat guys, fat girls, fat whoever really, I don’t mind one bit. However, that’s not how this world is like.” Malleable straightened up, placing a hand upon Saddle's waist. She flinched from the sudden contact, watching as the strange appendage caressed her trim middle.

“Whether they say outright or not, every celebrity you see on TV is the same. Thin or muscled, flaunting their perfect form in front of cameras, setting the standards for everypony. You wouldn’t believe the number of mares and stallions that spend so much of their time grafting away at the gym, eating pitiful meals and starving themselves to keep up with the trend. It sickens me to my stomach… if I had a stoma… you know, I’ll just avoid organ related phrases…”

“Regardless, I’ve despised how this world villainises fat, how it hates and discriminates against the rotund. And don’t think either of you are exempt from this problem either. Whether you like it or not, showing off your respective powers helps to reinforce the mentality. That, and I wanted to see the limits of how my formula would react to individuals with interesting properties… shall I say.”

“So… what exactly does the formula do?”

“Why, it makes you fat!”

There was a pause. “F...fat?”

“Tubby, chubby, obese, rotund. Any descriptors for, big, round and fat! My body can produce chemicals which can fulfil any purpose I desire. By eating lots, I can convert my excess slime into a whole cocktail of wondrous power, one which I’ve been stockpiling for months. Properties include a whole raft of little tricks and traps to turn anyponies body into one that resembles a mound of bread dough; rapid digestion, ludicrous amounts of calories, metabolism suppression, oh… and severe addiction. Ready to be injected into all Dreambury products to be dispatched across the nation! Ha ha ha ha!”

“That’s crazy, you’ll never get away with it! Our friends will come and find us, and we’ll spill all your secrets!” Fili burst out, drawing a bone chilling cackle from Malleable.

“Oh really? You mean the friends who allowed me to sneak into your headquarters undetected and take you? The ones which are still deep in sleep? The ones that have their entire computer network compromised? By the time I’ve finished with you two, they’ll still be none the wiser.” Smiling, she stretched her arms out. Before the pair could react, she stuffed her hands into their mouths, muffling any retort. Her arms bulged out, thickening as slime travelled along their lengths, pumping into their mouths.

The pair struggled, feeling a sweet taste blossoming across their taste buds as a mouthful of ooze was deposited into their maws, crawling down their throats. They didn’t have any time to think, overwhelmed by the intense flavour as more and more settled in their tummies. Indeed, as more and more travelled into the heroines, the less they resisted. Rather than squirming and mumbling, they relaxed more and more into their seats as their minds were flooded with a torrent of chemicals, dopamine amongst them. Soon, those muffled shouts turned to moans and sighs, their struggles petering out to nothing at all.

Satisfied with her work, Malleable retracted her limbs, smiling at the rounded stomachs the pair now possessed. Quickly, she watched them shrink down, their trim middles replaced by a little bit of fat. Nothing to really worry too much about, but in their skin-tight clothing, they were more than noticeable. “Now then ladies, how was that then?”

“I… I want…”

“More!” Fili interrupted Saddle, a sentiment quickly shared by their bellies, as they gurgled and groaned, feeling so utterly empty. Malleable smiled, grabbing the hoses and shoving them into their mouths.

“Well now, I think I can provide you with some more. Though I must warn the two of you, I have much, much more. Oh, and be careful. It’s awfully fattening…” Giggling, she grabbed at the nearby control panel, pushing a lever forwards. The pair felt a rush of air blow down the hoses, the rubber vibrating and shifting as something was pumped through. Following the lines, they could see a series of small bulges making their way down, getting closer and closer by the second, until finally they reached the end. Their mouths were filled with a similar tasting fluid to before, though it was subtly different, slightly more flavours and a little sweeter too. Regardless, it tasted divine, the pair greedily swallowing the mouthful, almost instantly replaced by another electrifying mouthful.

The heroes soon fell into a steady rhythm, every few seconds sending thousands upon thousands of calories to their thoroughly podgy guts. The slight coating of fat had expanded, replaced now with a pair of pot bellies, visibly pushing further and further outwards with every swallow. Malleable watched on in undisguised glee, looking at the control panel again. On either side of the console, a pair of dials continued to tick upwards, displaying Fili and Saddle’s weights. Already, a good 60 pounds had found its way onto their frames, a trend that wasn’t going to slow down any time soon.

“Look at that! You’re both already looking far healthier than before. Nothing but skin and bone.” Her gooey hand rested upon Fili’s belly, gently squeezing it as it steadily ballooned outwards. “Don’t worry, I’m here to save you from such a dull life of diets, exercise, and jealousy. No thoughts now, just keep drinking, and grow big and fat for me…” the two moaned gently, their enjoyment undisguised as the addictive chemicals within latched onto the pleasure centres in their brains. Slowly, their bodies began to fill up the seats, as new fat began to accumulate across their forms. While their bellies were the most obvious in terms of growth, their plot cheeks were taking on a good amount too, puffing up and out as their thighs thickened up. Lithe arms were fleshing out from the beginnings of bingo wings, just as their breasts were filling out too, the tight fabric of their suits conforming to the new mass, eagerly showing off every millimetre of growth.

Quickly, they passed 100 additional pounds, the dials ticking higher and higher every second. Any evidence of their previously thin, well exercised forms had been buried as more and more fat piled on. Their guts continued to bulge out, a flabby set of love handles growing out from the now obvious roll. Already, their costumes were providing some slight difficulties to growth, especially with Saddle. Her belt held back much of the growth, forcing her gut to ooze above and below, creating a faux double belly. Fili’s remained as a singular pot belly, sagging forwards onto her thighs, her suit showing off her deepening belly button, gradually becoming wider and flatter as her gut expanded.

“Now how about that? It’s only been a few minutes, and the pair of you weigh double what you started with. Imagine that… over half your body weight is made of soft, creamy, juicy lard. Just imagine in a few minutes more when it’s two-thirds, four-fifths, even nine-tenths of your body?” Fondling their folds, she gripped and wobbled their love handles, drawing a loud moan from Fili and a far quieter one from Saddle. “But why just stop there? I have more than enough of my solution to spare for you two girls. More than enough to have you weigh over a ton, maybe five, maybe more! You’ll be nothing but mountains of thick, undulating blubber, unable to move anything. And the only thing you’ll be doing, is begging me for more, not caring as you outweigh and outsize dump trucks, nothing more than masses of pink and yellow…” Malleables voice had become thick with excitement and pleasure, her imagination spiralling out of control as she watched her fatties balloon in size.

“But… that can wait. Before we can get there, we need to get you girls fed. Afterall, you’re practically skin and bones!” Grabbing the lever, she pushed it forwards another notch. The near-inaudible whine of the pumps increased in volume, harbinging the imminent shift in feeding. The bulges increased in size, moving along the hose at a far greater speed. The two mares stuttered at first, caught off guard by the shift. Soon though, they’d both adapted to the sudden influx, their throats rippling with every immense mouthful forced in. Their bellies gurgled, blorped and groaned in protest, the chemicals within helping to kick digestion into overdrive. The results were very quick to manifest. Before her very eyes, Malleable watched as the heroes were wrapped in ever more layers of pure blubber.

At this point, they were well and truly fat, way beyond simple ‘winter-weight’. Clearly struggling to find new places to store the deluge of calories, their bodies shunted excess into other parts of them. Their faces filled in, growing rounder as their cheeks blew outwards. Already, they both developed a second chin, wobbling about with every hearty gulp, with another looking to move in below that. Their necks too hadn’t been spared one bit, beginning to be encompassed by a ring of flab that slowly was beginning to merge with their head flab. Breasts too were swelling bigger and bigger, the mounds heavy with fat and milk, gently sloshing as they swallowed.

Wider and wider, their forms seemed to ooze outwards like dough overflowing a bread pan, continuing to fill the spacious seats. Saddle winced, her pleased, docile look turning to one of discomfort, her belt the clear culprit. The purple material was hugging her tightly, constricting her like a python as it cut deeply into her belly. “Oh my, looks like those outfits of yours are becoming a little too small. Don’t worry my dear filly, just keep drinking for me. Break that belt and show me that belly!” Saddle did as she was told, pulling on the hose to force more in. The belt grew tighter and tighter, the pain near unbearable to her as it squeezed her back and middle. The sounds of groaning fabric managing to cut over Saddles own pleading moans as she swallowed again and again.

Taking one massive gulp, she felt her belly press that little bit further out, the sounds of tearing reaching a crescendo. With a final tear, the belt was ripped asunder, her belly surging forwards. The pain and pressure were gone in an instant, encouraging her to suck down more and more as her belly spilled onto her lap, wobbling around from the sudden jolt. Two thick stomach rolls sloshed around within the tight confines of Saddle’s suit, Mistress watching in unrestrained glee as they began to sag off the edge of her lap, beginning their descent towards the floor.

“Goodness me, I thought these suits were designed for scrawny mares. I have to commend your tailor for making such flexible outfits.” She giggled, watching as the zig zags on Fili’s suit grew ever more curved, struggling to conform to the mare's ballooning legs and arms. Great ham like slabs of fat forced their way into the pair’s forearms, drooping in down and pressing into their puffy side rolls. “Gulp… ulp…. Ulp… grmmmpphhh… guullpp… ulp… nnnrrfff… sloooo… ulp.” The sounds of swallowing filled the room, the heroines having fallen into a steady rhythm, gulping down decadently delicious mouthfuls rapidly, their bodies all but ready to digest the calorific sludge near instantly. All the while, their tummies groaned, blorped and moaned, working harder than they’d done before to process the deluge of sugary goo.

By now, the chairs were looking more and more appropriately sized by the minute, both of their plots greedily gobbling up the ample space provided, sinking into the cushioned surface as their butt cheeks swelled outwards. Each doughy cheek was more than double their old size, creating deep chasms between undulating mounds, material stretching thinner and thinner, forced to accommodate such growth. Saddle moaned, feeling Mistresses probing hands press into a plump mound of butt fat, a shuddering sigh escaping the slime pony as she let the flab ooze around her grip. “Mmmnnnghhh… oh you're both getting soooo big, I’m so proud of you two. You're growing ever so plump, soft and beautiful… but you could be so much bigger.”

Hopping back to the controls, she turned the dial up once again, the hoses rippling and bulging as the liquid rushed down, forming an almost continuous torrent of liquid calories. Such was the volume, the two struggled to keep on top of the ceaseless deluge, muffled whines and groans issuing, trickles of pink spilling from their lips as they tried in vain to swallow it all. The results upon their physiques were staggering. Like watching a balloon being blown up from an air tank, Mistress watched as their bodies fattened. Their bellies continued to sag further down, Saddle’s belly developing numerous rolls as Fili’s reluctantly split into two enormous slabs of pure lard, her belly button lost between the giant crease.

“Now that's more like it, I can finally start calling the two chubby, now you're each a few hundred pounds apiece…” She tittered, grabbing one of Fili’s boobs, a sputtering groan causing more pink fluid to leak out, trickling down her triple chin. “Why would you ever want to risk your life fighting dastardly villains when you could spend your time indulging in the finest pleasures, I can offer you?” Weak moans of affirmation drifted from the heroes, their minds drunk on the debaucherous feeling washing through them, content to watch with glazed eyes as their bodies were subsumed into a growing prison of their own making.

At this point, calling them anything other than obese would-be folly, the superheroes each pushing well over 600 pounds of adipose, over a collective half ton of fat wobbled and sloshed around. “ssssSSSRRRIIPP!!!” A loud tear suddenly filled the air, a hole suddenly appearing around Fili’s belly. Mistress watched as a clump of pink porcine pudge pressed through the opening, forcing the tear wider to accommodate the mare's rampant hyper obesity. A few moments later, a similar tear came from the over side of the room. A great buttery roll oozed its way through the rip in the turquoise fabric, the hole enlarging as more fat pushed into the breach.

“Goodness, what wonderful bellies you’ve grown. So plump and oh so soft. This is what a real diet does to a mare: it makes them sexy and round! Starving yourself with disgusting salads to maintain an ‘ideal’ body, eughhh…” she grimaced, spitting a glob of herself into the floor, only to slide back over and reabsorb into Mistresses body. “No, you two will become perfect… all you’ve got to do is drink and keep growing fatter and fatter… could you do that for me~” cooing, she heard their affirmations, distant yet lustful moans.

Like a shedding a second skin, the heroes' suits buckled and tore asunder, more holes appearing with every swallow. Joining together, enormous gouges allowed for thick globs of adipose to pour forth. Meaty bingo wings and ample forearms expanded, starting to overlap one another like overinflated water waders. Their cuffs were becoming tight, wrist fat and blobby cankles pushing at the restraints. Their butts grew as large as pillows, eagerly devouring what room remained on the seats. A few scraps of material covered their surface, showing off their stretched cutie marks. “Hmm, I wonder… who’s bottom will be the first to outgrow the chair. I think that Saddles got the bigger cake out of the two, though your derrière is certainly not slacking Fili.”

Every few mouthfuls, she watched as their butts jumped outwards a little further, crossing the distance to the sears edge in a few moments. With a smirk of amusement, Mistress watched as a fold of plump yellow fat hung over the edge, gravity tugging upon the edges as her body sagged towards the ground. The last remnants of their suits clung around their forms, scraps becoming trapped between rolls, their very bodies devouring the last parts of their outfits, leaving overstretched panties and bras in their wake. Only Saddle’s domino mask remained, utterly redundant without the rest of her get up, the corners of the mask covered by the edges of her cheeks. No longer restrained, the compressed flab pushed further out, forming great aprons of blubber that dropped lower than their knees and onto their cankles.

The numbers of the screen ticked higher, the two of them reaching 900 pounds and cruising right on past. “There we go, a healthier weight don’t you think? Healthier, but certainly not enough. A thousand pounds, a half ton of supersized mares ballooning before me.” Laying a hand upon one of Fili’s belly rolls, she gave it a jiggle, pink blubber sloshing around like a pendulum in an earthquake. Eager appendages grabbed and played with any roll or fold that caught her fancy, smiling as she carefully looked more closely upon the changes wrought upon the speedster’s body. Here and there, numerous tiny folds appeared, new curves and swells of flesh as her body struggled to add more fat to her body. Cellulite dimples dotted the edges of rolls and great sagging blobs of pink that dropped from her limbs and torso in great creased drapes. Her boobs struggled, the milky flesh forced around the doomed garment, forcing them upwards.

Reaching an arm around, she found the clip holding the two cups together. The metal has bent, deforming further as the breasts swelled up yet another cup size. It was hard to tell otherwise, the great globs of back fat swallowing the fabric. “Again, I must commend your tailor for making such durable garments. Those milk balloons you call breasts must be bigger than basketballs by now.” Reaching a gooey appendage into the crease, she grabbed the fastener, and worked it free. Like a gunshot, a loud snap echoed through the room, Fili’s overstretched bra flying through the air, her now exposed boobs jiggling, showing off her perky nipples. Completely naked, nothing was left to imagination as bubble-gum fat wobbled about, sagging heavily as her rolls grew and grew with the constant influx of empty calories.

Moments later, a similar snap-crack rang out as Saddle's bra failed spectacularly, traveling the entire length of the room. With the last of their clothes gone, there was nothing to impede their growth. As the minutes flew by in a haze of wonderful flavour, their bodies expanded ever further outwards. Every minute, they lost more body definition, coming to resemble an amorphous blob rather than any living creature. Quickly passing 1000 pounds, the heroes struggled to escape the sweet, fatty prisons they’d been consigned to. Their minds flooded with pleasure, any thought of resistance was quashed, the only thing wandering through their minds was the simple command to eat and eat and eat.

Mistress Malleable was so focused on watching the numbers on the scale going up, she almost missed the flashing red lights flicker on the console, a low giggle leaving her mouth as she glanced up at her victims. “You know girls, I designed those seats to be able to hold several hundred pounds, and you’re already reaching their limits. Go on fatties, break those chairs, let those wrecking ball asses demolish them entirely!” Their feasts continued, enormous cheeks and jowls wobbling as they sucked down every mouthful, pounds added to their frames rapidly as more and more rolls oozed over the edges of the seats. Dull, metallic groans mournfully wailed as the metal was stressed to its absolute limit. With shaking hands, Malleable pushed the pumps to go faster, the pressure dials dangerously spiking as the flow cranked higher.

“Go on you blubbery pigs, break them… break them… break them!!!” She screamed, the metal responding in kind as it let loose its own final cry. ‘Kkaarrunnncchh!!!’ Simultaneously, the reinforced columns gave out as they crumpled in on themselves, sending the seats slamming into the ground, along with their oversized occupants. Over a ton of super-sized super mares came crashing to the floor, the room shaking from the artificial tremor they created. The impact dislodged their feeding tubes, tumbling from their mouths, streams of the fattening solution spraying across their bodies as the hoses danced about. Mouths no longer blocked, the ground shook again as both mares let loose a collective ‘BBBBOOOUUURRPPPP!!!!’. Reacting quickly, Mistress jogged over to them, watching as litres of purple liquid coated their gelatinous bodies, dribbling across their rolls, pooling in between folds, and oozing down their immense curves.

Catching their eyes, she could see both of their blue eyes were glazed over, a dull, hypnotic trance in their fattened features. “Mooore…” A needy groan poured forth from Saddles lips, eyes slowly focusing on the swinging feeding tube. She tried to reach out, her arms struggling to reach. Like a pair of overinflated inner tubes, enormous meaty bingo wings dangled from her upper arms, puffing out and squishing against her smaller forearms. Puffy fingers struggled to bend as she helplessly reached out, the desperation in the immobile mares’ actions more than a little amusing for Malleable. Grabbing the hose, she held it just before Saddle. “You want this, don’t you? You’re so addicted to my formula; your blubbery belly is crying out more…”

“Please… I’m… shooo… hungry… uurrpp!!!” Saddle moaned; her voice made huskier from the great collar of fat hanging around her neck. Covered in food and fat, she was a great wobbling mess, desperately rolling her tongue around her mouth to try and clean up any spilled remains. “Feed me… please Mistress…”

“How polite of you to ask. Of course I’ll feed you, good pigs deserve to be fed…” With a deft motion, she shoved the hose back into the yellow mare’s mouth, happy grunts issuing as the feeding continued. Wandering over to Fili, the speedster was in much the same situation, desperately trying to reach the hose, but unable to move… utterly immobilised. Every pathetic movement she made with her arms, caused her body to slosh and wobble about, folds and rolls squishing together, whining as her fingers only just grazed the feeding tube. “Here you go, growing mares need all the food they can get… especially if they’re growing into supersized mountains of lard.” Patting Fili’s belly, she wandered away, content to watch as the heroines continued to blob out.

Their bodies widened, rolls thickening and multiplying as the relentless barrage of calories poured into the mares. Without the chairs and their built-in scales, it was impossible to tell exactly how heavy the two were getting, the two of them well on their way to weighing well over a ton. She watched in glee as fat overlapped fat, rolls growing and oozing over other curves as any available room was fought over, cellulite pockmarking more and more of their soft, gelatinous frames. Chins upon chins flowed from their faces, as thick and doughy as pancakes as they swelled over each other, merging with puffy jowls and neck rolls. Their legs grew wider and ever more misshapen as fat sagged from each appendage, thighs turning into giant pillowy globs, unable to be separated from one another as the barrel sized lumps flowed across the floor. Their butts blew up behind them, each a great misshapen orb big enough to fill up a sofa, liberally pockmarked in cellulite dimples, creases and folds. Their cutie marks had been stretched to billboard proportions, forced to conform to the enormous canvas they’d been magnified across.

In front, their bellies grew wider and longer, mattress thick slabs of pure adipose piled high into humongous mounds of blubber, the great stacks of fat helping to support their mammoth breasts. Belly buttons were deepened by the great folds and rolls that had formed around them, turning into deep caverns and canyons that could swallow a pony whole. Ringing around their sides, enormous love handles puffed out, each as thick a pillow and just as plush, providing ample space for their roll-stricken arms to rest upon. Behind them, a staircase of back fat had formed, the number of creases and rolls giving them an accordion like appearance, the lowest bulge of fat resting upon their vast plot.

Devouring space like they devoured the slime, the mares who’d once been spaced so far apart were right next to one another, their vast stomachs pressed together like a pair of continental plates slamming into one another. Forced to not only fight against themselves for space, but against each other, their stomachs squashed and squeezed against one another, forcing the fat to bulge upwards, pink, and yellow lard mingling as it pressed together. Whatever remains of the chairs had long since been enveloped, hidden beneath vast, saggy, boulder sized plots. Mistress Malleable managed to peel her eyes away from the awesome spectacle to glance at a few control panels. Catching her eye, she looked at the readout for the goo storage tanks, scrolling through the data, finding it much to her liking.

“Well girls, I think I can call the test a success, just think that only an hour ago you were so wretchedly thin, you’re now so much more gorgeously voluptuous! Rubenesque forms brought to their extremes, makes for such wonderfully blubbery beauties!” Despite her proclamation, the tubes continued to pump, Malleable tapping away at the console. “Though that test may have concluded, I’ve still got many more tests lined up… would you lardy ladies be interested in testing how prolonged consumption of the formula affects a ponies waistline?” Two enthusiastic moans were the only answer she needed, “Excellent, let's start by draining the first storage tank… you’ve only managed to drink 1% so far… plenty of calories to keep you piggies growing nice and fat…”

Alt Ending

Evening was drawing in Ponyville, Celestia’s sun making its slow descent through the sky in preparation for Luna to take over and bring in the Night. Darkness was beginning to take root, and many ponies were starting to turn in for the night as the shadows grew long as the sun dipped towards the horizon. Inside of Twilight's castle, things were quiet, all of the castles’ guests having left by now. The rooms were almost all quiet, most left bereft of anycreature. A library, one of many in the vast castle, was suddenly bathed in a sudden flash of light. Blinding white rays of light erupted forth, two shapes following quickly afterwards, landing heavily in a pile before a crystalline table. Almost as soon as the light had appeared, it was extinguished just as fast. Laying sprawled out on the cool floor was Pinkie Pie and Fluttershy.

Confused, they looked about themselves, picking themselves off the ground. Reaching down, Fluttershy pressed a hand to her middle, finding her middle was as trim as it always was. “What… what just happened there?” she spoke finally, absentmindedly playing with a strand of hair.

“It was like that comic that Spike had! You know the ones with the Power Ponies, and Maretropolis and superpowers and…”

“No Pinkie, I mean… why was it so…”

“Fetishitically lewd and debaucherous beyond belief?” A small eep escaped Flutters lips, her cheeks flushed a rosy red. “Not a clue, unless it was written that way…” Pinkie wandered over to the table beside them, a magazine laying upon its surface. Flipping it back over to the front, she could see the title “Power Ponies: Mistress Malleable and the Obesity Agenda.” Emblazoned on the front cover, two massive almost-naked ponies were sitting apart from one another, strapped into ill-fitting chairs. Standing between them, an amorphous blob in the shape of a pony, a devious smile playing upon her lips as she watched the captive ponies fatten up. Casually, Pinkie flicked through the book, the events on the page matching up very closely to the strange, but oddly pleasurable experience she’d just gone through.

“Yeppers, seems like it to me… wow, whoever this artist was really had an eye for detail.” She mused, oblivious to the bright shade of red Fluttershy had turned, flipping it over onto its back. “Want to experience this tale yourself? Simply press firmly upon the rear and speak ‘Begin Again’”.

“But how did we get pulled in? I don’t remember touching it, or saying anything like that… the last thing I remember was that I was just walking by the door, and I suddenly got dragged into the light.”

“Oh, because I was in here, I saw this laying on the table like this and thought, why the hay not? I’m pretty sure this thing pulls things from pretty far away too… I don’t know, strange magic doohickeys or something like that.”

Fluttershy blinked, surprised at Pinkie's admission, sighing as realised who she was trying to rationalise things with. “Whatever happened, it makes you wonder why Twilight’s got something like this laying around?”.

“Now Fluttershy, we shouldn’t judge ponies for their tastes, even if they do involve turning mares into barely recognisable whales of fat in a kinda submissive, domineering sorta way, you know.” She paused, a low grumbling emanating from her middle, followed quickly by a burbling groan from Fluttershy’s tummy. “Whoops, hehe, guess it's been quite a while since we’ve had something, I’m starving.”

“Me too, I’m feeling so empty.” She rubbed her middle, trying to calm the sudden dull twinge of hunger. “It’s pretty late out now, do you mind if I go to Sugarcube Corner with you?”.

“Ooh, Absoloutsy-tootsy! I’m sure Mrs Cake can fix us something good. How come you want to go there?”

Fluttershy shrugged, making her way towards the door. “I’m not sure, but I’m strangely craving some chocolate right about now…”
