Chapter 1

Night had drawn in, the light blues of the day replaced with dark purples and inky blacks, dotted with innumerable pinpricks of light that sparkled amongst the distant heavens. The colder atmosphere drew in cool winds that blew through all available gaps they could find. Candles flickered as their flames danced from the gust. Curtains shifted and jostled around, occasionally catching on raised surfaces.

Princess Celestia glanced up from her book, momentarily distracted as one candle she was using to read dimmed, ears easily picking up the faint whistling coming from the closest window. Tearing her eyes from the page, her horn ignited, casting a brilliant yellow glow across her bedroom. A slight creak of hinges could be heard, followed by a light ‘thwap’ as the rubber seals on the edges thumped into the wooden frame. Breathing a small sigh, she turned her attention back to her choice of reading material. Covering the page was a quadruple layer cake, sliced into the side, showing the spongy, chocolaty mass forming the centre of the impossibly massive dessert. A low, needy gurgle welled up from depths of her stomach, forcing their way through literal meters worth of soft, doughy fat.

Celestia was not a small mare. A fact that was made apparent through many compounding factors. Her bedroom for one was more like a ballroom from its sheer scale alone, her bed composed of dozens of king-size mattresses. The palace bill for food cost too was extraordinarily high. The chief purchases including pastries, cakes and the ingredients to create more of them. But what was most apparent was how much of a blob she was. The culmination of hundreds of years of rich, fatty diets and little exercise had turned her into an avatar of obesity. Conventional scales no longer could measure the mare turned mountain, the last weigh in had required the use of dedicated heavy-goods wagon scales. They’d been pushed to the point of failure and the mechanism required several months’ worth of repair work.

A hill of wobbly blubber, with a pair of tits that could comfortably crush trees. Her fellow princesses could only match her sheer monumental size. Smiling at the thought of consuming such an immense treat, she was just about to turn the page of the book, when a sudden flash of green light appeared before her fat swaddled head. Celestia could only just tear her gaze away, watching as the misty apparition materialised into the form of a scroll. Her smile remained as she caught the letter in her magic, spotting the wax seal stamped onto the paper, bearing a familiar symbol.

“Oh, a letter from Twilight? Wonderful! I haven’t heard from her in a while… I hope she’s doing alright.” Celestia mused, breaking the seal with a light tug, unfurling the paper. Her expression, however, quickly soured, a deep frown creasing and dimpling her cheeks.

“Dear Princess Celestia,

I first want to express how sorry I am that I haven’t been in contact as often as I should. The reason as to why I’ve neglected contact is because I’ve been concerned about a few things. I want to be fatter, but at the same time, I don’t. Truthfully, my friends have been telling me I deserve to grow larger and blossom to the size a Princess of Equestria should be. And I would love to expand my form to match your own, but I feel that such a desire is wrong.

I haven’t earned it. How can I have earned the right to join the hallowed ranks of the Princesses of Equestria by doing so little? How can I compare myself to yourself, Luna or Cadence by putting in so little on my end? I haven’t led a nation for millennia. I haven’t toiled and suffered eons upon a desolate alien world. I haven’t nurtured and led an isolated, imprisoned city to great prosperity. Besides, I was only crowned less than two years ago. I can’t expect to get everything handed to me on a silver platter, can I?

Though I am still small right now (if you can consider weighing 549 pounds to be small), I can afford to wait around for a decent while longer. Thank you for reading the Princess. I know how busy you are. I apologise for wasting your time with the ramblings of a spoiled, entitled mare. I mainly wanted to write this to you to get this off my chest, so I’m sorry about the prose. Thank you and have a wonderful evening.

Your Student

Twilight Sparkle”

Celestia’s eyes darted up and down the page, drinking in every quill stroke. A tightness twinged at her core. “Oh Twilight…” she whispered, burying her face in her neck fat in an approximation of a facepalm. “For being such an intelligent mare, she can be so silly.” Humming to herself, she closed her eyes, inhaling and exhaling slowly. Opening her warm, pink eyes, she smiled, three pieces of paper floating up to her face. “Well, I suppose now’s a good time as any to have a little get together. Let's see if we can’t change her mind…”

Twilight gulped, trying in some vain attempt to moisten her dry throat. She clambered up a set of steps, feeling her form gyrate and slosh about like a water balloon, only just contained within her clothes, which in of themselves were rather casual for royalty. A rather old white t-shirt clad her upper torso, clearly many sizes too small, her sizable gut oozing out the bottom and smacking against her chunky thighs. Below, a pair of bright pink stretch pants had just about contained her bulbous bottom, obvious holes and gouges dotted across the fabric, like somepony had attacked them with a pair of scissors. Alas, it was her own obesity that had buckled the overtaxed material, her unwillingness to upgrade her wardrobe leaving its impact on the few survivors of their owners ballooning size.

The hall she gingerly plodded through made her seem miniscule in comparison, however. The hallway was easily as wide as one of the smaller abodes in Ponyville, with an equal amount of headroom. So large was it that each step she took echoed around her, bouncing from the polished stone, encasing every side of the cavernous room. Up ahead, a pair of immense doors were set into the wall, two guards standing on either side. Seeing Twilight approach, they saluted, armour clanking in unison with their feet pounding the ground.

Hastily, she offered a sloppy salute of her own. “I...I’m here to see Princess Celestia.” She stuttered slightly, the two guards nodding and lighting their horns. Twin flares of blue and gold flashed into existence, enveloping the massive door handles. With an almighty tug, they creaked open, revealing nought but darkness.

“She’s been expecting you, Princess, please enter.” One of them spoke, Twilight nodding and slipping into the darkness, doors slowly closing behind her.

“H...hello? Princess? Is anypony there?” she questioned. Suddenly, light flooded the room, forcing her to shield her eyes. “Gahhh! Princess, I…” She stopped as she gazed up at the behemoths surrounding her. If Twilight was fat relative to the average pedestrian, then Twilight was positively skinny compared to the looming masses of adipose crammed into the room. Each could crush an average Ponyville house, their bodies far exceeding any reasonable proportions. Cadence, for as big as she was, was rather well rounded. Her bust, ass and belly had taken roughly equal amounts of blubber, keeping her proportions very similar. This wasn’t true for the older two.

‘Dump truck ass’ was a commonly used term for a mare with a more generously proportioned rear. However, this was more than apt at describing Luna’s own posterior, each cheek larger than said dump truck. Her crescent moon cutie mark alone could have covered a billboard. Celestia, on the other hand, had cultivated two large orbs on the opposite side of her body. It seemed as much of the growth had channeled its way into the sun princesses breasts. Literally bigger than entire milking sheds, each mammoth orb gently sloshed and wobbled with every breath she took. “Luna… Cadence… Celestia, you’re all here?”

“Indeed, young Twilight. We came at the behest of my elder sister.” Luna spoke, her deep, booming voice almost seeming to shake the very foundations of the room.

“We want to have a little talk with you Twi, after all you said in that letter.” Cadence spoke next, her voice possessing a deep undertone of concern.

“I… er… what?” Twilight sputtered, her mumblings cut off by her mentor.

“Precisely. What you said in that letter you sent to me has made me rather concerned for your wellbeing.” Celestia spoke softly, yet firmly.

“But what… no, Princess, I...”

“Twilight, please. We’re all princesses here. Within this chamber, and indeed anywhere else across Equestria, we are free to call each other by our names. Cadence, Luna, I, and you, Twilight. Because you are a Princess.”

“Verily, sister. I do not know what doubts or daemons have crept into your mind. Whatever silly notions of inferiority that have been stewing in that wonderfully intelligent mind of yours need to cease this instant. The feats and challenges you’ve overcome in but a few short years are nothing short of astounding.” Luna continued, nodding towards Cadence.

“In the last few years, this nation has both experienced its greatest time of harmony, and some of the largest periods of unrest and turmoil in a millennium. And do you know who was the one who helped to solve almost every one of those problems… you. And before you argue it was not just you, remember, who was the one pony that brought everyone together in the first place? Who was the mare who brought 5 strangers together and defeated Nightmare Moon and purged it from Luna? Who was the pony who lifted the corruption from your friends and vanquished Discord? The one who rescued me from the Canterlot Caves? Who helped to restore the Crystal Empire? Sacrificed the Elements of Harmony and her own magic to save the Tree of Harmony and stop Tirek? These things and many, many more minor problems you’ve solved. Without you, Twilight Sparkle, the Equestria we see today wouldn't have existed at all.”

“I… I don’t...”

“Twilight. My former student and now fellow Princess, you’ve earned your place amongst our ranks, no doubt. If there is anypony alive today more deserving of having her dreams come true, that would be you. You are as selfless as they come, and are far, far from being spoiled. Your hard work and dedication to all pursuits, whilst admittedly can be a tad excessive, is wholly commendable. You’re never content to leave a job as ‘good enough’. Outstanding bravery, leadership skills and a great work ethic are all traits that make you, you.”

“Well put, sister. I do not wish to read such slander about yourself ever again. We all have our flaws, I, the most so out of everypony here. Nopony is perfect, and we all have our moments of doubt and pain. We have had our shared deeds and heroics, as have you, and certainly more so than Celly has had in several centuries.” Luna tittered, Celestia giving her a mock glare from where she sat. “But the point remains. You have every right to attain the size we all share.”

Twilight stared up at them, running a finger by her eye, wiping away a stray tear. “Thank you. I don’t know what to say.” Celestia smiled, giving a minute nod towards her peers.

“Say nothing yet. I invited you here for more than one reason, Twilight. Not only to hear our words on why you’re worthy, but to grant you the opportunity to catch up to our size.” The solar princess said cooly, gauging the expression etching its way onto Twilight’s face; a deep curiosity twinkled in those eyes as she nodded. “Should you choose, we can provide you with a quick way to get just as big as us, if you’re ready, that is?”

Twilight stoked her double chin, feeling it bounce as she quickly processed the question. “Yes… absolutely yes! After everything you’ve said to me, it’d be rude not to take your offer.”

“Do not feel you have to take it. You are under no obligation to do so. Don’t think about what we may or may not want, instead, think about what your heart desires the most, dear Twilight.” Luna corrected her. “It’s your body, and your decision alone to change it.” Twilight nodded, gulping slightly. Her fingers drummed along her thighs, eyes screwed up as she breathed deeply. A few seconds passed, her eyes opening suddenly.

“I’m going to do it.” She simply stated. At those words, Celestia’s horn glowed its familiar golden hue. From behind the titanic mare, Twilight watched as a small, brown ovoid levitated towards her. No bigger than her hand, she could finally see it was some sort of pastry… a sticky bun, perhaps? The surrounding magical glow seemed to shimmer and dance off the white icing generously covering the top, giving the simple food item an almost ethereal glow. “Is… is that it?” Twilight muttered, feeling the weight and the stickiness in her outstretched hand.

“Indeed, it is. I can see your confusion, so I’ll cut to the chase. As you know, fat is simply a storage of all the excess energy the body cannot use immediately. So, we thought the best manner in which to get all that energy, and by extension calories, would be to imbue a simple food item with powerful spells to give it the energy.”

“All of us did Twilight. I’m not sure how much power we put into that thing, but we probably spent about an hour each doing so. Let's just say that this little pastry is probably one of the most magically charged things in Equestria, barring actual creatures and artefacts like the Crystal Heart.” Cadence continued, watching as Twilight turned it over in her hands, feeling how unnaturally dense the pastry was.

“Suffice to say, when that treat pass’s your lips, you’ll become be as big as we are present.” Luna finished. Beads of sweat trickled from the smaller alicorn's forehead, eyes flicking from the pastry to the princesses and back to herself. Before anypony could say anything more, Twilight suddenly crammed the bun into her mouth. Like a starved wolf, the dessert was little trouble for the seasoned glutton, as she tore it apart in a matter of moments. Licking stray smudges of icing and sugar from her lips and releasing a small burp, the room fell into a tense silence. The seconds ticked by, Twilight blinking as she inspected herself. Opening her mouth, any words were cut short. A low, rumbling groan reverberated out from Twilight's core, her gut rippling like a pond.

Like a flood, every square inch of her body seemed to leap outwards. Twilight’s clothes didn’t stand for very long, her already overtaxed t-shirt exploding into confetti as her boobs, arms and back oozed outwards. Similarly, her sweatpants only had a bit more stretch left, her ass and thighs eclipsed that extent in a fraction of a second, escaping their pink prison. “Nnnnrrhhhr mmmpphhh...” A low, guttural moan rasped past her curled lips. Every second spent was one of pure ecstasy as it flooded her brain with a deluge of pleasure signals. Her hands immediately flew towards her belly, grasping, hefting, and groping. Her hands curled and grasped around each new fold and roll she could notice, face becoming ever more flushed as she found more and more pockets of blubber clinging to her form.

Gripping her ass, she bit her lip as her panties were stretched to their breaking point, turned into spaghetti thin strands as they battled with the encompassing mass of booty, swallowing them up. The elasticised material dug deeper and deeper into her crack and burgeoning love handles, her sensitive flesh pinched as the garment attempted to stem the growth, swallowing them up. With a ping, they too failed, much like how her bra was becoming engulfed by tit flesh that ballooned over the cups. Battling both her tits and roll encrusted back, they were quick to fail. The hooks bent and buckled, springing apart with an explosive crack, her tits surging forth.

A tingle danced up her spine as her belly raced to meet the floor, spreading across like rising dough. Further it inched its way along the marble, dominating feet worth of space under a tide of purple. Moments later, her ass cheeks also made contact. She cooed, feeling the cold stone press firmly against her own amassing bulk, the feeling intensifying by the second as tingling bolts elicited from every amassed inch of flesh. Staggering slightly, her immense weight was making any sort of movement from her legs increasingly difficult. Combined with the enlarging rolls that had made legs resemble stacks of beanbags, she could bear the weight no longer.

With one last motion, she collapsed, sitting back on her ass, a fleshy slap complimenting a muffled moan. Her expansion continued on. No longer fighting against gravity to stand, the immobile alicorn could take in the near euphoric feeling of her body growing before her eyes. She could feel how her rolls grew and how they fought for space, with other rolls pressing themselves outwards. Her bottom blimped up bigger and bigger, her cutie mark becoming more stretched and distorted across the vast canvas presented. Between the forces of her belly and butt, she was gradually being raised up, as if somepony was pushing cushions beneath her. She flexed her fingers, biting her lip as she failed to bend them more than a twitch. Her fingers, no, her body was so encumbered by thick drapes of lard, coaxing any form of mobility from herself was useless.

Doubly so, as she felt her arm and calf fat swallow her hands and feet. Twilight tried to wiggle her toes, only to meet a thick, juicy padding of fat. Even her neck could no longer twist, a great wodge of neck fat encircling her neck, partially merged with face cheeks that jiggled with little effort. A waterfall of chins budded forth, partially integrating with the inner tube of blubber thickening her neck. From around this cocoon of flesh, she watched as her peripheral vision shrink, narrowing to an ever tighter point, just about allowing her to see her eyeline reaching higher and higher as she crested her fellow Princess’s rolls. Each one of her belly rolls was thicker than her bed back home, bed frame included as tons of blubber continued to materialise.

A deeper blush engulfed Twilight’s massive cheeks as her gut finally pressed into her opposite numbers. Despite the three leaving a massive gap from the door, the scale of Twilight’s growth had finally covered the room provided. Like tectonic plates colliding, Twilight could feel how her fat squished and squashed against the equally soft mounds of the others. Rolls that could fill entire rooms alone were pressed together, partially interlocking as they took the path of least resistance and squeezed between folds. She could feel the immense, sloshy mountains of Celestia’s tits, her head sized nipples poking and prodding her thickest fat roll.

Up and up she continued to rise, catching sight of Celestia’s face hidden amongst her own collection of face fat. The solar princess’s eyes held nothing but happiness, alongside a very slight undercurrent of arousal, presumably from the soft, firm contact between the two of them. But she watched as Celestia’s eye’s disappeared under the swell of her own ponderously huge boobs. She was getting bigger than her mentor. Luna still gazed down, on account of her bigger butt, but the gap was rapidly closing, especially regarding Twilight's monumental belly. With a few more groans, blorps, and strange bodily noises, everything became still. With one final tingle of growth flowing across her skin, Twilight noticed her expansion halt.

Blinking slowly, her mind catching up to her newly gained proportions, she took stock of her surroundings. Though she couldn’t see it, she could feel how her belly rose and sagged partially into her fellow princess’s own guts, the sheer enormity of her being simply staggering. Arms and legs still trapped within their pillowy prisons, tons of blubber swaddled and covered her entire world. So large was she that she eclipsed her old house for sheer size. Given her apparent height, she was actually slightly larger than her fellow princesses. So huge, so round… she could feel tears welling up.

“Thank you! Thank you everypony from the bottom of my heart. This, this has been everything I’ve imagined. I’m so… so big!” her voice wavered, both from her bubbling emotions, but from the increased effort it took to speak.

“You’re more than welcome, Twilight. I couldn’t have possibly denied such a request after everything you’ve been through.” Celestia smiled.

“Verily. Even though dreams are my forte, I have no qualms with helping individuals fulfil their dreams in the real world too.” Luna chimed in.

“Exactly. Myself and everypony here will be in much better spirits knowing you’re alright. You’ve gotten so big Twili, I’m so proud of you…” Cadence sniffed. Pressed up against the ponies she’d looked up to for years, the warmth they radiated from their bodies soothed her. Shifting her mass slightly, she could feel three enwrap their bodies in their magic, pulling themselves closer. A great squash of pink, purple, white and blue. All four of them came together in a close approximation of a group hug. Arms wrapped around her or not, the simple presence of those ponies she admired, bodies interlocked in an immense blubbery pile, it was everything Twilight could have hoped for.
