Chapter 1

The atmosphere inside the Castle of Friendship was one of peace and serenity. It was an early morning, Celestia’s sun only just cresting the horizon. From a doorway, a head emerged, glancing back and forth down the hallway, scanning for anypony. Nothing. With a happy sigh, she closed the doors behind herself, before locking it with an audible clunk. A burst of magic erupted from her horn, coating the wall in a small barrier of purple. “Perfect, everything is ready. Spike’s gone with the guys to an O&O convention for a few days, Starlight is busy doing some administrative work for the school…”

Twilight Sparkle was dressed in a simple t-shirt and shorts, not exactly princess attire mind you, but she didn’t care particularly. Right now, she was all alone, and ready to have some fun. Picking up a large, heavily faded leather-bound tome, she flicked through to a red bookmark. Cracking open the noted page, she quickly rechecked the casting matrix, confident she had it committed to memory. At the top of the page, the name of the spell, with subsequent details was laid out.

‘Body Expansion – Growth by Weight Gain. This spell allows for the user to designate either themselves or another creature to rapidly gain weight. The degree of development of fat upon the creature is dependent on the caster's relative power and duration over which the casting occurs. Additional effects include: Increased stomach capacity, degradation in hygiene, increased levels of flatulence. These can vary on a case by case basis, however. To reverse the spell, utilise the counter spell listed below. This will remove all traces of weight gain and any additional effects from the target.’

You see, the alicorn of magic had a rather dirty little secret. Ever since she was a filly, she had been fascinated by ponies that were, on the larger end of the weight spectrum so to speak. She was entranced by how little they cared about their outward appearance, how they crammed an entire family’s worth of food into their wobbling, sagging bellies. She wanted to experience that. She NEEDED to experience that. However, she didn’t want to go through with anything like that. Her mother would have thrown a conniption if she did anything like that. So, she kept her little fantasy a secret, all the way into her entrance into Celestia’s school, all the way into her private tutoring under Celestia herself.

Just as she had become a young adult, she was browsing through the restricted section of the Canterlot archives, looking at the myriad of forgotten tomes. After flicking through stacks of dusty, poorly maintained pieces, she grasped another one with a blank cover. The damaged spine creaked, she inspected the inside cover. Inside, written by hand was the title - ‘Body Modifications; a guide to altering yourself and others.’ The author's name was unfortunately covered by some gunk which had stained the page, permanently blotting the identity of the individual forever. However, judging by the age of the tome, it was unlikely he or she was alive still. Curious, Twilight decided nopony would miss it, and tucked it into her backpack.

After getting back to her house, provided by Celestia for the duration of her studies, she slipped it on her desk, plowing through the pages. As the name suggested, the pages were filled with details upon the most bizarre and sometimes horrific ways you could alter someponies biology. There were often omitted details, or areas which were certainly works in progress. Additionally, there seemed to be virtually no limits on how perverse or intimate they got. It ranged from innocent incantations to make your ears larger, to make your mane and tail longer or to make an individual develop long buck teeth.

But what really interested her was the section marked ‘Full Body Alterations’. As she flicked through it, moving past instructions detailing how to turn a pony into a blueberry, she stopped dead in her tracks. Just seeing the words ‘Weight Gain’ made something rise inside of her, some urge that tugged at her mind. Within a few minutes, she had grown a tiny bit of chub, clinging to her belly, giving her a definite layer of softness that she had never once experienced.
From then on, it had become her form of private pleasure, to turn herself into a wobbling fatty. She was addicted to the feeling of her body growing that little bit larger every time, having it ruin numerous sets of clothes she had laying around for just the purpose of having them contort around her flabby mass, before exploding off. She also found out that any food she ate whilst in the fattened state would not affect her normal body. This led to her buying countless boxes of greasy, calorie packed treats that she crammed into herself, leaving herself covered in numerous stains.

She didn’t care though, a quick shower after slimming back down was a simple fix anyway. Besides, she loved how sloppy her manners were, thinking about how ‘uncouth’ she was acting. Just imagine, Celestia’s prized student and now Princess of Equestria, being as well kept as a sow. Admittedly, this attitude had bled through into her normal, thin life on more than one occasion, namely when she went to a hayburger and got a little too carried away with those greasy, delectable patties of deep-fried hay. Clearly, this utilisation of the spell every week or so for the past few years was having some deep effect upon her psyche, but at this point, she was much too far gone to even notice this.

A smile creased her cheeks, longingly looking over to a small red velvet cake, standing alone upon a crystal table. “Time for a bit of indulgence, I think.” Sitting her thin frame down on her Queen-sized bed, she lit her horn surrounding her form with the same aura that coated the walls. A moment passed, her skin tingling and forming goose bumps, the spell just about to activate. Seconds later, she felt her frame start to bloat outwards at an alarming pace. Her face, thin with well-defined features, almost seemed to melt, as it began to round outwards. Thin cheeks fattened, developing a notable swell as they did, turning into tennis ball like slabs. Her chin gained numerous followers, stacked on top of each other like pancakes.

Her smart shirt began to untuck itself as her belly began to push its way out of its confinement, rounding out larger and larger until it was the size of a beach ball. This was joined by a thick slab of love handle that muffin topped over the edge of her straining shorts, laying heavy atop her plump thighs and plot. The mare let out a small moan of pleasure as her tight shorts began to self-destruct, her growing orbs of plot fat creating great welts in the material. Further below, her enlarging legs were doing a similar job at breaking through her socks. She grinned dopily as her melon like boobs turned her t-shirt into a tube top, the bottom of her cleave plainly visible below as they lay heavily against her top belly roll. A couple seconds later, the blimping tits were freed with a deafening ripping and tearing, allowing the creaking tortured bra below to restrain them.

With considerable effort, she reached behind herself with ham like arms, pulling her buried panties from out of her ass crack. The light blue pair let out a small twang as she released them, rippling her ass with a wave of jiggles. Cooing, she placed her hands on her cutie marks, watching in fascination as they were wider than her outstretched palms and fingers. She let the spell continue for a few seconds more, allowing more lavender flesh to ooze across the creaking bed frame. Just as she felt her undergarments begin to cry out for mercy, she finally released the energies blimping her figure. Closing her eyes, she revelled in the weight of her body, how gravity seemed to tug at every overhanging slab of blubber.

She suddenly remembered the dessert, waiting for her on the table. Eyes filled with a near primal hunger, she lunged forward, snatching it up in her fattened hands. Hefting it up, Twilight dove face first into it. “Mmmmmm, Oh it’s so gooood!” She mumbled through the mouthful of cake. Flecks of crumbs tumbled out of her lips, landing amongst a carpet of white icing as her hands continued to funnel the red velvet into her mouth. The family sized treat was devoured as easily as if it was a cupcake. With her sticky hands, she licked the remaining cake gunk off each digit, futility trying to remove the coating around her face with the back of a hand.

“Ahhh…Pinkie always makes the beBUUOOOUURRPPP!!!” She was cut off, as a massive eruption of gas rose out of the immense pit of her stomach. Giggling, the alicorn mare gave her full belly a small rub, feeling her malleable flesh deform around her palm. “Oh, it’s so good to indulge… to be such a gluttonous fatty…” Bringing her hand up, she let it fall, producing a loud slap after the impact. An amorous moan bubbled up as her hands roamed across her form, grabbing and fondling each contour and pocket of flab her greedy fingers could encircle. Hefting her tits up, she smooshed them together, lustful moans filling the room as jolts of pleasure sparked inside her. She roughly mashed them around, her hands sinking heavily into the orbs of milk and fat as they sloshed around.

Pausing for a moment, Twilight lay back, the bed making loud protests as she did, those titanic plot cheeks causing the frame to bend ominously. Soon, she continued to play with herself, lewd fantasies beginning to manifest in her head. What if she was to go outside looking like this? Ponies staring in horror, confusion or perhaps arousal as her entire, near naked form came waddling along the high street. She imagined sitting in one of the stalls at Sugarcube Corner, handing over sacks of bits as she consumed the Cakes entire stock, her body becoming ever larger, perhaps even immobilised by her wobbling, shaking, juicy flab. Perhaps even somepony else would help feed her, walking across layer upon layers of alicorn lard, as her body was coated in mounds upon mounds of food, staining her coat into a patchwork of colours. Perhaps even…

She cut off her own thoughts as she climaxed, letting out a lustful moan as her thighs were slickened by a deluge of mare cum. Giving her belly one last squeeze, she released her grip, panting heavily in the afterglow, beads of sweat running across her body. Drumming her rounded fingers against the swell of her butt, she gathered enough strength to haul herself unsteadily to her feet. “Phew…now that was…huff…pretty good.” Wiping a hand across her forehead, her horn flared to life, bringing the spell book over.

“Shame good things come to an end…” she mumbled, rechecking the counter spell, just to be sure. Activating her horn, she wrapped it around herself, giggling slightly as it tickled deeply into the deep pockets of flab. With a small flash, it activated. A second passed, followed by a few more, followed by even more time. Glancing down, Twilight was surprised she was still large. Eyebrows knotting in confusion, she performed it again. Still nothing, still no change. By now, her lust clouded mind was clearing, being replaced with a gut wrenching feeling of dread. Something was not right. “Come on, I’ve done this hundreds of times! Why isn’t this working?” She half shouted, becoming more agitated.

Biting back a curse, she tried again and again. Nothing. Flicking back to the page, she scanned through the article, eyes frantically bobbing across the lines of text and diagrams for a solution. She noticed a small asterisk right next to the bottom, with minuscule text reading ‘Index for further information’. Rapidly flicking through to the back, she found the corresponding page number, with a small box written beneath.

‘Body Expansion – Growth by Weight Gain – A notable problem can develop as a result of prolonged or repeated usage of this spell. Due to how the incantation alters the body in its entirety, residual magic can build up overtime as it permeates body tissue. This can alter the figure on a base level, so much so that the weight thaumilogically developed can never be removed by the spell, as this consider the ‘base state’ for the body. Whilst the individual can gain weight beyond this point, they will only lose weight back to the generated weight. No amount of exercise, diet or other magic can remove this fat, or any side effects stemming from the initial expansion’.

She stood there, reading and re-reading the paragraph. “No no no no no! No! Celestia above, what the hay am I going to do!” Pacing around, she tried to blot out the lovely sloshing and jiggling of her form as she tried to concoct a plan. Furthermore, she tried to ignore a growing hunger within herself. “What if I just hide myself away? Surely I’ll be fine if I just stay inside and figure out something to cure me?” Another pang of hunger lanced through her abdomen, wincing as she placed a hand upon the wide swell of her belly rolls.

“Ehehe… maybe not. But how can I go out and get something to eat? It’s not like I can cover myself…” She trailed off, a burst of inspiration hitting her like a tonne of bricks. “If I can’t remove it… I can hide it instead.” Horn flaring to life, she began to construct a new incantation which spread across her entire form. Looking over at the mirror, she watched as her obese form shrank away, growing thinner and thinner. With one final manipulation, the disguise was in place.
“There we go! One glamour spell ready for action. Just so long as I can hold it in place, I should be fine.” And fine she did look. Rather than the clinically overweight, stained mare dressed in enough broken and overstrained clothes to make Rarity faint, she looked normal. Trim figure, smart casual clothes and no unsightly marks. “Time to head out and grab a snack or two.” Snatching up a bag of bits, she waddled towards the door, before the wet, sticky feeling between her thighs brought a blush to her face. “Well…after I change, that is…”

After stretching another ill-fitting pair of panties around her giga thighs and ass, Twilight set off. Stepping out of the castle almost naked was certainly an odd experience. Especially when ponies greeted her normally, a mixture of friendly waves or small bows. At least it was a good litmus test to whether her illusion was working, and unless everypony had suddenly found walking in your underwear normal, then she was fine. Not one pony mentioned anything behind her back in hushed whispers.

She could feel the immense power of Celestia’s sun pounding down upon her vast tracts of ‘land’, at a mostly pleasant temperature. It might have been slightly too warm from the layer upon layers of natural insulator padding her better than a winter coat. This combined with the task of moving a body weighing more than double her old size was taxing. Afterall, she almost exclusively did her enlarged sessions in the privacy of her room, moving around too much was not much of a concern. Now though, it was a reminder of all that permanent ballast blanketing.

Breathing a small sigh of relief as crowds ignored her features, she continued onwards, aiming for the marketplace. The only thing she had to do was wave back at other’s greetings. Although that was becoming harder and harder as she tried to focus on walking normally. Whilst the spell hid her form, her actions were not. As such, she couldn’t adopt a more comfortable waddle or shuffle, having to grind her massive legs past one another, feeling all that immense blubber sliding around up there was really affecting her ability to concentrate.

“Hey Twi! How’s it going?” A sudden shout came out from above the adipose alicorn, a loud yelp escaping her lips.

“Rainbow! Don’t scare me like that!” Twilight harrumphed.

“Oh pu-lease! You are so easy to wind up, I don’t even have to try.” The prismatic maned mare descended from a fluffy cloud above, her powerful wings allowing her to glide down with little effort from her fit, partially muscled body. She landed with a small thump, a small cloud of dust flying past her legs.
“Anyways…how have you been doing egghead? Haven’t seen you in a while.”

“Oh, you know, this and that. Just finished with some boring Princess stuff, I suppose you’d say.” Twilight said with a small gesture of her arm, the invisible flab wobbling from the motion. Her head still facing Rainbow, she continued, prompting the Pegasus to follow, lazily flapping her wings to not get too far ahead of the blubber bound mare.

“Heh, yeah. Anyways, what are you doing out of the Castle, you got some friendship mission to do?”

“Err… nothing like that.” Her eyes darted back and forth, wracking her brains for something. “I was just getting some fresh air you know, maybe do a little bit of exercise to keep on top of my fitness.” A small chortle hissed past Rainbows lips, making a poor attempt at covering it.

“Oh man, that’s a good one. Next you’ll be telling me you want to do weightlifting with Bulk Biceps.” A small look of annoyance crossed Twilight’s face. “But you got to admit, going out to do exercise isn’t something you do, at all. What’s the change all about?”

“You know, just to keep the body ticking over and all that stuff. Make sure I’m all healthy and all that caper?”

“Right…although from the looks of things, no offence, I think you need it. I know you don’t do much, but I don’t think you should be sweating from such a light walk so much. Hay… it isn’t even that hot today.” Twilight reached up to her forehead, touching it. Immediately, her hand was spotted in multiple drops of liquid. Glancing down, she saw more rivulets dancing and flowing across her abundant form.

“Eheh…you know…I did just finish a bit of a jog earlier you see. Hard work you know.” She gave a wide smile, prompting Rainbow to return with a raised eyebrow.

“Rrrright…but you said you just been doing some Princess stuff. And I saw you just walking and waving to everypony.” Twilight was sweating harder, her grin becoming wider and more manic. “And why are you walking funny as well?” Twilight could feel more and more perspiration pooling across her body, so much so it was practically glistening in the sunlight.

“Well…you…huff…see…erm…” She glanced around, searching for some excuse. “Well…you see…oh sweet Celestia is that A.K Yearling?”
“Where?” Rainbow whipped around, eyes flicking around the group of ponies behind her. Her keen pupils rapidly scanned the myriad of individuals, concluding that none of them was the famous author/archaeologist/treasure hunter. “What are you talking about Twi? Have you got a screw lose or something?” Turning back, Twilight was already long gone, having made it a significant distance down the road. She couldn’t help but continue to notice the exceedingly odd way the purple pony carried herself. Almost like her legs were stiff. Something just didn’t add up here.

“Hmm…something’s going up with Twi…I’d better get to the bottom of this.” Musing, she spread her wings, leaping into the air with a powerful gust of wind in her wake as she spun off into the sky, in pursuit of her quarry.

After ‘escaping’ Rainbow, the purple mare trekked further on her way, heading for the marketplace. All manner of stalls was set out across either side of the road. Brightly coloured signs and awnings dotted their way along like a patchwork quilt, each desperately trying to grab the individual’s attention. It was like an assault on the senses entering this place. Loud hollering of ponies advertising their wares, combined with the clink of bits as they changed hands feverishly. Products of all shapes and sizes were bartered or sold, from notebooks, to perfumes. From furniture to gardening equipment, there was something for everypony, regardless of hobby and interest.

But what got Twilight was the smells. Oh, the wonderful smells that billowed their way through the market. From the freshly picked blooms of the flower trio, to the body wash and soap from the spa twins. However, she wasn’t interested in those. Oh no, it was the mingling of fresh, delicious cooking that was causing a small line of drool to slip from the corners of her mouth, followed promptly by an angry growl from her belly, causing a few nearby patrons to look around.

“Shhhh, don’t worry, I’ll get you something nice and filling.” Continuing her journey, she considered each stand, looking at portion size, queue length. Cuisine type was also considered, from Mareixcan, with their pots of chili and nachos, pillow like burritos lined up in rows. To Neightalian, thick, stuffed crust pizzas, oozing with gooey cheese. To Germane, with thick Bratwursts, packed into fluffy buns, with a sprinkling of grilled onions and lashings of any condiment she could choose.

Just as she was still pondering, she caught sight of a brown Stetson, poking up amongst the crowd. Twilight’s eyes opened in wonderment, as she caught sight of what was next to that same hat. A stack of pies balanced atop one another, with small trails of steam rising from them. And better yet, no queue either! With an exaggerated lick of her lips, she took off like a cruise missile, albeit a terribly slow, rotund missile at that. Body shaking, she lumbered forth with as much grace as a hippo on a unicycle. As she got closer, the store owner noticed Twilight, giving her a wide smile as she approached.

“Well howdy there Sugarcube! Lovely day ain’t it?”

“It sure is Applejack. Been getting some fresh air and I was whilst I was working getting rather hungry; I was wondering if I could buy pie from you?”

“Well sure you can! As if that ain’t one of those rhetorical questions or what have you. It’s 10 bits a pie, fresh from the oven.” A split second later, and a bag of gold bits was thumped down onto the hard wood counter, slightly rattling it’s sturdy frame. Darting her hand out, the alicorn plucked one of the golden-brown creations. Wrapping her hand around the corner, she bent the thin metal tin, before pulling out a small chunk of the pie. Gooey browned apple filling made itself apparent with a burst of sweet, sweet aroma. Bringing it up to her mouth, she took a bite, groaning happily from the exquisite flavours.

“Eh…don’t cha wanna, I don’t know, sit down and eat?” Applejack suggested, watching with bated breath as each mouthful caused the mare to increase the rate of her consumption. Cramming more and more, she didn’t even feel the slightest bit full as specks of filling spattered her mouth. With a couple more bites, she finished it, giving her belly a small pat. Applejack’s curiosity grew as she noticed that, for some odd reason, she didn’t touch her thin gut, seemingly bouncing off thin air. Before she could get a word in edgeways, her hand darted out again, scooping up another delectable treat.

Manners were thrown completely out of the window as Twilight continued to devour the pastry with all the care of a sow eating at a trough. Occasionally using her hands to catch a falling glob, she had devolved to just shoving her face into the treat. As she finished the second one, she let the tray fall with a dull clatter against the cobbles below. “Mmmmm, that’s so gooBBBUUURRPPP!!!” She exclaimed, sending a few flecks of crust and apple falling to her massive breasts below. Applejack watched in bewilderment, her confusion further growing as the filling seemed to disappear before touching her shirt, almost like some sort of barrier was there.

“Twilight, what in the name of Celestia has gotten into ya? You’re eating faster than a pack of vampire fruit bats through a bushel of apples.”

“Well, actual…UUURRP…ally, it’s a colony of bats, not a pack. Second, I’m just feeling a bit hungry today, you know? Reading all those books really makes you hungry after a while.” Applejack could smell something fishy already.

“Uh huh… I thought you had to be physically dragged away from your books by Spike to even get the smallest bit of food in ya. Last time it happened, he said that he’d threatened to burn all ya work until you would get up.” That same wide grin spread across her face, continuing to ring alarm bells in the farmers head.

“Well you see, I was trying a new technique, loading up on calories to keep me full though my study sessions. Yep, that’s what I’m doing, loading up on calories.” Applejack was tempted to keep pushing, but something made her stop. If Twilight had some secret or problem, she was probably going to let it out sooner rather than later.

“Ah well, doesn’t matter. I just hope you enjoyed my pies as all.” Another small burp came Twilight’s lips, not even bothering to cover her mouth.

“Oh, it is as amazing as always Applejack. Oh, I’ll just get one for the road as well…” With a wave of her horn, another crispy pie floated off the pile, hovering around shoulder height. Quickly, she pivoted on the balls of her feet. This was a rather poor decision on Twilight’s end, as all that excess, invisible butt blubber came swinging around like a pendulum. It grazed the work top, before smashing into one of the tins, causing it to skitter away from the impact. Applejack watched it fly like a frisbee before hitting a wall, confused on how it had moved like that, how Twilight had knocked into the desk, but not actually knocking into it.

Turning back, the apple mare watched as Twilight disappeared off into the crowd, heading further into town. “What in the hay just happened?” She paused, picking up the bit pouch. About to call out to the alicorn, she was already long gone by the time she flicked her eyes up again. Straight into the magenta orbs of Rainbow Dash.

“Land Sakes! What the hay you are doing right there Rainbow, can’t ya see I’m busy with something?” She grumbled out. The prismatic mare rolled her eyes, picking up the tray on the floor.

“Well, have you noticed that Twilight’s acting reallllllly weird today?”

“Yup… she was as ravenous as a snake in a chicken coop. Why do ya ask?” Taking a deep breath, Rainbow pointed out all the oddities she had noticed with the purple alicorn in their last encounter. Scratching her head with one hand, Applejack's confusion turned into one of concern. “Well, if what you say is true, and I don’t see a reason to distrust you on this one, I definitely think that girls got something to hide.”

“Yeah, no kidding. Anyway, I saw her heading further into town, I think it looked like she was going to Pinkie’s place. You want to come with?” Glancing around at the disinterested crowds, AJ gave a small shrug.

“I’m in Sugarcube. Now let’s get moving before we lose her!” With that, the athletic duo sprang to action, leaving a gaggle of confused shop goers in the dust as they powered on ahead.

With a satisfied belch, and a well-aimed toss of the near spotless tin into a bin, Twilight licked her lips of any remaining remnants of Apple family cuisine. “Truly, there was no greater comfort food around”, Twilight thought out loud, her hand sinking into her flabby hip as she approached her target. “Well, maybe not the best, after all, no one quite makes a cake like Pinkie Pie!” Skirting her way around a few ponies, she approached the oddly decorated structure. If she didn’t know it was all coloured plaster and brick, she would most certainly have taken a bite out of it.

Grasping at the candy cane shaped door handle, she gave it a firm push, making it swing open with alarming force, forgetting about her excessive poundage behind the shove. A small bell tinkled lightly, allowing a bloom of delicious smells to fill Twilight’s nose, drawing another needy growl from her already partially full belly. Fortunately for her, it seemed the bakery was lacking patrons at the moment, giving her a straight shot at the counter.

Looking around, she had to restrain herself from leaping out to grab at the myriad of treats lining each and every corner of the store. The most delicious looking area was the wall of candy. Lollipops and candy canes were placed in wide jars, the hard and glossy treats glinting in the pleasant lighting. Taffy and Liquorice were wrapped up in huge jars, teasing Twilight to buy a handful. Aniseed balls and rosy apples were just some of the mouth-watering treats fillies and colts could whittle away their pocket money on, along with the super sour suckers, for those willing to stomach those tart bombs. Teddy bear sized Gummi bears wobbled slightly as the heavy footfalls of the obese mare picked her way across the floor, almost like they were fearing for their life against this devourer of treats.

Approaching one of the desks, she heard the door to the kitchen creak open, allowing a figure to enter from behind the display cases. A pink maned pony, dressed in an equally brightly coloured apron came pronking into the room, her wide smile growing even wider when she caught sight of Twilight standing there. Compared to thin Twilight, she had a small layer of chub covering her body, giving her a small pot belly that pressed against the fabric. Though, compared to Twilight’s current appearance, she looked anorexic. “Hey there Twilight! How are you doing on this fandabidozi day today?” With a small twirling jump, she plonked herself in front of the register, ready to whip up what she assumed would be a cupcake or cookie.

“I’m doing just fine Pinkie. Just taking a small break from work to catch some fresh air, you know?” Pinkie gave a small nod, her springy mane bouncing around with each rapid bob of her head.

“Oh yeah, I know exactly what you mean. Besides, if you were here to get me for a friendship problem, I would have been way ahead of you on that one.” Pinkie giggled, prompting a small laugh in return, slightly painful memories of attempting to understand the mare’s spontaneous nature rather fruitless. “So, what can I get for ya? We have some fresh doughnuts, Trottingham style with jam filling.”

Twilight put a hand to her face, letting out a low ‘hmm’ as she weighed up her options. She could just get a box of cupcakes, say it was for her and Spike, and leave it at that. But looking past Pinkie and into the kitchen, she noticed several cakes, freshly iced. A greedy, selfish idea popped into her head, like a siren song calling out to her. She couldn’t, it would be so wrong, her brain was screaming at her. But her heart and especially belly overruled it. Who could resist a freshly baked Pinkie Pie cake after all?

“I’ll take a cake.” She finally said.

“Sure, what slice do you want? We’ve got chocolate fudge, toffee, coffee, raspberry, marble, vanilla, red velvet…” Pinkie rattled off an impressive list of flavours, each as amazing sounding as the last.

“Chocolate sounds good. Oh, and I don’t want a slice. I want the whole thing.” Twilight breathed out, hardly able to contain herself at the monstrous order. So monstrous in fact, Pinkie did a small double take, before grabbing the aforementioned goliath of a culinary piece. Triple tiered, with thick layers of icing, sprinkled with shavings of yet more chocolate, this thing was a sight to behold. Placing it down on the counter with a hefty thump, the sheer weight and mass causing the glass to shudder in its frame. A stream of saliva trickled from the mare’s mouth, dumbstruck.

“Well, that’s 200 bits right there. Are you going to make a payment now, or should I put it on your tab?” A pop of magic rang out followed by another thump, metallic sounding and significantly lighter, answered her question definitively.

“There, that should cover it. Thanks Pinkie!” Lavender aura encircled the cake, picking it up with little effort as it hovered at head height. A smile at another successful sale crossed Pinkie's lips as she bounced over to the till, depositing the coins in with a satisfyingly loud clink of gold and silver.

“Don’t mention it Twi. I’ll catch you at the party later, OK? You can’t have ordered a cake that big without first putting a little get together, together, right? Who’s going to be there? Is it the whole town, just us girls, the Princesses? Because I need to check my party schedule, I’m fairly certain there is nothing planned for tonight.” Placing the last of the coins safely away, she only got silence. Head popping back up like a whack-a-mole, she found nopony was standing there.

“Err…Twilight, where did you go?” She called out, getting nothing in response. “Did Twilight just teleport away without giving me the time for her party?” Her eyes narrowed, musing out loud. “Something’s not right with her…”

“I’ll say Pinkauuuugh!” Suddenly the door flew open, disgorging a blue Pegasi and an orange Earth Pony onto the wooden floor.

“Wait, were you two eavesdropping? Cause that’s something you should never do to a friend.”

“Yes, we were listening in. Listen, somethings not right with Twilight now. She’s been acting all strange this afternoon.” Rainbow quickly scrambled to her feet, dashing over to Pinkie in a flash, Applejack following on behind her.

“While I don’t like doing this sorta sneaking stuff, trying to discover her secrets and what not, I think that something has happened, and she ain’t telling nopony nothing.” Applejack continued, adjusting her Stetson with a flick of her wrist, joining her colourful comrade.

“Yeah, nopony would ever just order a giant cake like that and just run away before telling somepony about their party plans.” Rainbow scratched the back of her neck, not sure on how to continue.

“Eh, sure… anyway, I think we should go and confront her back at the castle about all this weird stuff she’s been doing.” Applejack gave a small nod.

“Eeyup. We’ll have one of the intervention things and make her tell us what the hay is going on. If she does, we can help her fix whatever the problem is.”

“Wellllll, when you put it like that, I think it’s fine.” Pinkie nodded, before vaulting over the tabletop. “Let’s get ready to go!”

“You know sugarcube, you could have just gone around the side there.” Applejack deadpanned.

“Shh…it isn’t cinematic if I just ‘go around’” she shot back. Applejack glanced at Rainbow, who shot back with a small shrug of her own. Afterall, it was Pinkie ‘being Pinkie’ as usual. “Now let’s go and get some cake…and help our friend out with her super duper secret she is hiding from her best buddies that may or may not be eating away at her from the inside!” With that, they shot out of the building as a unit, leaving a bemused looking Mrs Cake, which turned quickly into joy as she checked the till.

“Next stop, the castle of friendship!”

With a flash of light, Twilight reappeared in the map room, still letting the cake hover around. “Phew… note to self, make sure to account for additional mass when teleporting, that took way too much energy to do.” Placing the dessert down upon the crystal table, she wiped her forehead, for what felt like the umpteenth time she had done so today. But now though, all by her lonesome, as that beautiful creation of chocolate and sponge, sitting there innocently.

In a split second, she was upon it like a tiger descending upon it’s prey. With greedy hands she tore great hunks of sponge out, icing oozing through the gaps of her fingers as she crammed it into her mouth. Standing there, her body invisibly jiggled and wobbled from each exaggerated grab and needy pull she took on the rapidly diminishing cake. It was carnage, as crumbs and flecks of grated chocolate and icing spattered across the smooth surface of the table, a trail of destruction winding its way up her blubber rolls like a carpet. But she no longer cared for that, only that her tummy was hungry, and that this calorie bomb was divine. Already, her body was processing the mountain of sugar and cocoa down, new layers of flab swaddling her already obese form. Not that she really noticed, or if she did, would care. Afterall, when you are already this large, what a few extra pounds here and there?

A deep belch rolled out, finishing one of the tiers at a breakneck pace. A sickening amount of cake nopony would hope to eat in one sitting. And yet, she still hungered for more. Her stretched out stomach, whilst it was no longer growling, didn’t feel anywhere close to being full. After her small break, she continued, working away at the second layer.

The remainders of her already scant clothing were being stretched to the limit. Only just able to fit over her old size, the double threat of both her expanding butt and breasts were really testing the quality of the fabric. Another mouthful, and another tear appeared, allowing a clear sight at her deep purple areolas. A mouthful of fudgy icing, and her panties disappeared further into her ass cleavage. She could feel her belly now touching the surface, pooling against it like melted ice cream as her butt pushed against two of the thrones, flab squishing around the cool hard material. She was in food heaven, gobbling down as much as her heart desired, and it so desired to be enveloped in more and more flab.

By now, her lust was rising, growing stronger as she continued to fill herself up. She had always dreamed of doing something like this, just pigging and letting her gluttony run rampant. Her figure, at least in her mind, was beautiful. So heavy, cumbersome and soft…warm and squishy. And she was improving it with each stored calorie and glob of adipose ladened tissue generated on her. Who needed to work out, diet and exercise just to stay trim, when you could just laze about and eat anything you wanted? Just growing fatter and fatter and fatter. With one hand, she lifted her monster gut up, still guzzling down cake with the other. Just about to tease those warm, wet folds.

“Twilight? What the hay is going on?” A sudden shout rang out through the hall. In an instant, the flabby mare let out a muffled scream, her cheeks still full of chewed up sponge. Quickly pulling her hand out, she spun around, barely remembering to check if her glamour was still working. Filing through the doorway was her three friends, with a mixture of concern and suspicion plastered across their faces. Hastily swallowing the mouthful, she plastered her trademark ‘definitely nothing wrong happening’ smile on.

“Oh… hi girls, BUUURRPPP, what…err…. brings you here on this fine afternoon?” Judging by the worsening look of worry on all three of her friends' faces, they clearly were not buying it.

“Twilight let’s cut to the chase. Something ain’t right about ya, and we as good friends want to help you overcome…whatever it is your having problems with.” As her friends approached her, she took a step back, colliding with the bulk of the map/table behind her.

“Yeah, since I saw you this morning, everything you’ve been doing has been just that little bit off. Like the way you walked and how out of breath you were.”

“How ya wolfed down those pies like it was nothing.”

“The way you kept dodging questions.”

“How ya ate like a starving pig and didn’t get a single drop or crumb on yourself.”

“Oh…oh and how you just bought a cake that big for yourself! I might be a big eater, but I know for a definitive, absolute, most certain face that you wouldn’t be able to eat that much!” Sweat poured from the alicorns forehead like an open facet.

“You see….I err…” She began to charge her horn, ready for a quick blink away from this situation. Just as she was about to release it, she felt Pinkie’s hand suddenly wrap around the spire, breaking her concentration. The spell fizzled and failed to activate. However, it wasn’t the only spell to die. Her horn had been minutely glowing, so incredibly faintly that you wouldn’t see it in the light. Now, nothing was being projected. With an odd electrical sounding creak and groan, the charm died, allowing the three to see the devastation of her figure.

For a moment all was silent, Twilight looking mortified as everypony gawked at her now plainly visible figure. Everything was there on display. From her apron like belly, to her pendulous tits, to her globular ass. This also included the myriad of sweat and food plaster haphazardly across her body. An awkward silence fell between them, only to be stopped by the stuttering of Rainbow. “Wwwwhat in the name of Celestia happened to you? You’re…you're huge!”

“I’ll say, ya looked like you took part in one too many eating contests.” Applejack supplied, her mouth still open in awe.

“Wowee, you look soooooo big and plush and cuddly Twilight, I would have never guessed you had a feederism fetish.” The others looked like they were about to question Pinkie, but closed their mouth’s knowing that they had more important things to question that the party mare’s odd knowledge.

Just about dying from embarrassment, Twilight rubbed one of arms nervously. “Well, to cut a long story short, I have been using a spell for years to make myself…big. Well…hehe…it turns out that if you keep using it over and over, eventually it…” She trailed off.

“It what, Twilight?” Rainbow demanded.

“It’s permanent. I cannot lose this weight. Ever. I hoped to just hide it beneath a glamour spell, but it seems that you can’t really hide over 500 pounds of blubber, eh…ha ha.” Her cheeks were burning red. She felt so ashamed of herself right now, feeling like she was about to break down into tears as she closed her eyes. “I’m sorry I hid it from you, I was just so worried that you’d hate me for being weird.”

A loud gasp rang out, before Twilight felt something latch onto her from the front, wrapping her arms around her massive swell of belly. Opening her eyes, she saw Pinkie wrap her in a massive tight hug. “Twilight. Listen right now. We won’t hate you for anything like this. You’re our best friend in the whole wide world. We aren’t just going to drop you for something silly like this.”

“She’s right Twilight. Whilst this is, a bit odd I suppose, we won’t hate you or something like that.”

“Hay yeah! We’ll be with you all the way. Doesn’t matter if you have the body of a runner or a sumo wrestler, we’ve got your back Twi!” Rainbow put a hand on the purple alicorns shoulder, giving her a gentle rub. “Though...if you want to take up a bit of sumo wrestling, I wouldn’t mind coaching you!”

“Oh, that reminds me. Twilight, I need somepony to help me out in the kitchen. Somepony to help taste test to make sure all my treats are tip top and are judged in a non biased way. By the looks of that cake, I’d say you have the stomach for the job.” Pinkie added, her face somewhat smothered in boob flesh, something the party mare didn’t mind in the slightest.

“Girls… thank you…” Twilight mumbled out, close to tears as she wrapped her flab swaddled arms around Pinkie. She continued to embrace the party mare for a few seconds more, before breaking the hug. “Thank you for being my friend.” A smile, genuine this time, beamed out. This was ruined a few moments later. With her body still digesting, she was continuing to put on weight. With one final groaning creak, her bra detonated, allowing her nipples to come onto full display. Behind her, those string thin panties tore, pinging off like a catapult.

Awkwardness blossomed again, Twilight’s rounded cheeks glowing like the sun. “Err…oops?” Twilight supplied, before all of them broke down laughing at her misfortune. Trying to cover herself while chortling madly, she knew deep down, she was going to be fine.
