Beauty in Bulk

"Opalescence, darling!" The bell to Carousel Boutique jingled as its owner and resident entered. Rarity the unicorn walked along, swagger always apparent no matter what she did. Once she found the object of her call, a fluffy white Ponisian cat, she knelt down to give the feline a few loving pets as Opal nuzzled the dainty hand in response, "Today was absolutely FABULOUS, my dear dear Opal. Today Rainbow Dash and I spent a fantastic session at the spa and I got news that Sassy and Coco closed some very high profile deals at their respective boutiques." She clapped both hands together, holding them together. Opal meowed in response and followed behind Rarity as she walked into the kitchen, getting a bottle of sparkling cider and a wine glass out. The seamstress was happy and going to celebrate her win of the day and what better way to do so than with some delicious cider chilled in a fancy glass with some little ice cubes? The unicorn then moved over to her fridge and cracked it open to get some of the cold cubes out. Before she could, however, her bright expression changed to one of horror at what she saw.

"WAAAAAAAA!" Rarity shrieked. Normally, somepony having a reaction of that caliber would be attributed to seeing a large monster or something else present only in the worst of nightmares.

However, this was Rarity and the phrase 'dramatic' only began to scratch the surface to describe her. In this case, the object of her fright was a small cake decorated with strawberries and chocolate frosting.

"The cake Pinkie Pie got me for my birthday! I completely forgot it was in here!" She declared, "And she's coming over today for a measuring! If she finds that cake is still here...oh my stars, I can't even begin to think how she'd react." Rarity shivered, remembering an event in which Rainbow hid pies from Pinkie (referred to as the 'Secrets and Pies' incident by their friend Twilight Sparkle.)

"And I'm already full from having lunch with Rainbow! Ohhhh, think, Rarity! There must be a way to solve this whole thing!" She put a hand to her chin as she contemplated what to do. She then snapped her fingers as she rushed upstairs to her bedroom and pulled a book from the small shelf inside. Unlike the fashion textbooks and romance paperbacks that dominated it, this book was a spell tome she'd been studying to improve her magical abilities. Rarity flipped through the pages, putting her red, horn-rimmed spectacles on as she scanned the pages trying to find something. Eventually, her desperation led her to a spell described to increase digestion. Rarity took a deep breath and looked down at her slender frame. She knew that amplifying her digestive process would almost definitely cause her to gain a few pounds, but she needed to be able to have enough room to eat the dessert. She didn't want to hurt Pinkie's feelings, after all.

"I suppose I'll have to adjust this then." Rarity sighed, her hands moving down to slightly adjust the belt between her teal top and the purple skirt with her cutie mark stitched into it, “Two holes should do. Hopefully.” She lamented, already mentally planning the workout days that she was inevitably going to need. The pony set the book down on a reading table and focused herself to begin casting the spell. She thought of the food already in her belly and began focusing on wanting to make it digest faster. Her horn shined with a light magenta aura of arcane shimmering. Her stomach made a loud bubbling noise as she suddenly felt a strange tightness around her middle as it swelled slightly. Rarity winced from it, groaning at the pot belly she had acquired but quickly turned her attention to the sudden hunger she now felt, like she hadn’t eaten in hours.

Which then made her think of the cake. The fudge frosting covering it, the fluffiness inside it, the delectably juicy strawberry topping it; all of it sounded absolutely divine and she absolutely felt like she was going to enjoy scarfing it down.

“Scarfing?! Wait a minute, I am a lady! I would eat with much more civility than-” Her thoughts were interrupted as the magic around her horn burst, sending sparks across her bedroom and nearly blinding her from the flash as a startled yelp echoed out. Rarity covered her eyes with her arms, unaware of the remnants of the aura that enveloped her before disappearing. Slowly, she opened them, crystal blue irises blinking as the concerned tailor quickly checked her bedroom to make sure nothing had been broken or set on fire. A relieved sigh came as her fears were put to rest.

“I must be much, much more careful in the future.” She said, shaking her head. Almost in response, her stomach growled loudly and she could feel a slight tinge of discomfort, "Oh! Well, I suppose it worked then. I feel famished." She trotted back down to the kitchen, going for the cake and setting it on a table nearby while acquiring a fork. Rarity then stuck it into the side of the cake before raising it to her mouth. Moments after, her taste buds exploded in total ecstasy while a few sparks even hopped off her horn. She knew the pastel pastry maker's goods were delicious but darling Pinkie had apparently knocked it out of the park with this one. The soft cake crumbled satisfyingly and the frosting practically melted in her mouth. That first taste was enough for her to quickly start going after the cake and eating it very quickly in order to consume every delicious crumb.

What she wasn't aware of was how her eyes started to swirl and spin with various shades of blue.

"Wonderful!" She declared happily after finishing the cake, slouching in her chair while rubbing her slightly rounded stomach.

"Mrow?" Opal went as she wandered over, sitting below the table while staring up at Rarity. She tilted her head slightly as the pony ran her lithe fingers all up and down her belly, squeezing it and making some drumming motions that caused a reverberation throughout her gut. As it continued, Rarity moaned when she subconsciously slid a finger into her navel.

*KNOCK**KNOCK**KNOCK*

The rapping at her door broke her out of her stupor and abruptly ceased the rubbing session. While the event was strange, Rarity put it out of her mind and trotted over to the door.

“Coming~” She said in her sing-songy voice on the way to answer the summons, cantering along as her tapped tummy bounced in rhythm with her steps. Once she got close, she opened up the door and immediately found herself being pounced upon by a short, plump pink pony wearing an extremely bright yellow and pink shirt with a pair of denim shorts and thigh-high striped stockings that matched her shirt.

“Rarity, hi!” She giggled, her rather buxom chest firmly pressed up against Rarity’s more modest curves. A blush came over her face, which she found strange as this obviously wasn’t the first time the hyperactive baker had given her a hug but this time felt different, it felt good.

REALLY GOOD.

"Rarity? Are you okay?" The earth pony asked with slight concern while she loosened her grip.

"Hm?" She shook her head in response to her name, "Oh I'm fine, Pinkie darling. Just a slight surprise is all." The unicorn nervously chuckled.

"Oh, well that's good!" The bouncy pink pony clapped her hands, "I was totally worried I was squeezing you too hard, you were red as a cherry!" Pinkie giggled, making Rarity realize just how visible her blush was.

"Oh...not at all, my dear! Ha...heh." She went, waving a hand off, "So, Pinkie Pie, shall we get started with your measurement?" In almost a blur, an entire set of clothing flopped on the ground in front of Rarity's hooves and she suddenly had a plump pink pony wearing a magenta bra and panties in front of her.

"Go for it!" Pinkie grinned and struck a little pose.

"You seem quite eager." The fashionista took her tape out and walked behind the stripped down pony. She then began her usual process whenever she sized up mares for dresses, measuring underneath Pinkie's prodigious bust, around her plump waist and also took a little around her chubby neckline as well. As Rarity sat on her knees to take account of Pinkie's hips, she found her eyes drawn to the pair of round pink cheeks in front of her. While still fitting around her, the chubby gal’s panties did have some fat bulging out of them while her thick thighs squeezed against one another. Shockingly, the clothes maker observed that there was almost no cellulite or stretch marks present around.

“She must have some sort of regiment to take care of her skin and body. It’s so smooth.” She thought, gaze locked on Pinkie’s rear. Just smooth flesh. Round, chubby cheeks of soft flank.

So round somepony could just press their face right in.

Rarity blinked, shaking her head as she came back to her senses and finished up her measurements, praying to Celestia that Pinkie hadn’t noticed her voyeuristic gaze directed at the fat, juicy ass in front of her.

“Stop. Get a hold of yourself, Rarity!” She quickly stood up.

“All done!” Rarity said, “I will get those measurements processed, take your suggestions and you should have a fanciful new dress very soon, my darling.” Rarity smiled.

“Yay!” Pinkie turned and flipped around, looking right at Rarity before she stopped and tilted her head, the curly pink mane atop her head bouncing slightly, “You okay there, Rarity? You’re blushing and sweating.” The unicorn’s eyes started flitting about left and right. While it seemed as if Pinkie Pie was the most clueless of all her friends, she was able to pick up on the most minute of details if given even half the chance to do so.

“Just, um, excited to design his dress!” Rarity giggled, waving her hand, “Your measurements should be absolutely fantastic to work with.”

“That’s great!” Pinkie laughed as well, a snort coming in at the end, “I always get told my some stallions around town how cute I look and how my curves can carry a dress like nopony else!” She smiled and struck a sexy pose, causing the already flustered Rarity to become even moreso.

“Oh, Pinkie Pie, you have no idea what you’re doing right now.” Rarity forced a smile and chuckled.

“Always glad to help! Eement of Generosity and all!” She declared, “Well, is there anything else that I can help you with at the moment?”

“Nope! Just super duper extra excited about the dress!” Pinkie dove forward and gave Rarity another bear hug before turning and heading out toward the door.

“Um...Pinkie?” Rarity got the foodie’s attention, pointing a finger at the pile of clothes on the floor.

“Ohhh! Thanks for reminding me!” Another giggle from her snout before she scooped up the clothes and quickly exited from the boutique. A deep sigh of relief escaped from Rarity’s chest as she quickly closed her door behind her and then locked it, putting her back up to the door and glancing outside to see if Pinkie had indeed gone. Upon seeing that she in fact had, Rarity wandered into her kitchen.

“What in Equestria is wrong with me? I can’t for the life of me stop thinking about fat! And roundness!” She groaned, sitting down in the chair, “Pinkie Pie’s derriere was on my mind the whole time I was measuring her! It’s so unfair that my gaze was locked onto it!” She sighed, “And it’s even more unfair that said flank is so amazing! I am so jealous and I wish that I could capture the level of attention her body does, if only I were as hefty as she was!” Rarity whined before shaking her head, “I...no. That’s not what I want. Why would I want to get fat? I like the way I am, the way I look...don’t I?” Her voice quivered upon the statement. Her eyes then glazed over as they followed the same spiral pattern from before, “Maybe a little snack might help me decide.” She shrugged as she opened up her fridge and took out the materials to construct a sunflower sandwich (which started off as one and then quickly turned into four layered on top of each other by the time that she finished.) She sat down at the table and began quickly eating them with surprising ease given the gorging she had done earlier on the cake. Once she practically inhaled the first sandwich she moved onto the second, which tasted even better than the last. Rarity blinked in utter astonishment as she chewed into it, before eating the third and the fourth in rapid succession. Once they were gone and her stomach still growled for more, she reopened the fridge and started taking just the ingredients for the sandwiches out and scarfing those into her muzzle: bread, sunflowers, daffodils, condiments, it all went down her gullet.

What the white unicorn didn't notice was the development going on below her. Her slight pudge that had formed from consuming the cake was slowly bulging out. The loose teal fabric of her top became tight around the swelling flab and it started tightening around her belt as well with two rounded rolls spilling over the top and bottom that gave her the appearance of having a double belly. As she ate, though, her gut wasn't the only thing that started to grow. Rarity's hips began to thicken considerably, pressing up against the sides of the chair she sat in. Her flank started growing too, taking up the space behind her in the chair as its girth magnified with its roundness showing underneath her skirt alongside her considerably larger thighs.

"Mmmnomnomnom~" The faster she ate, the more she blew up. Like her belly, her chest ballooned and stretched out her top as meaty cleavage formed from her once modest-sized breasts as expanded into coconuts sure to make any boob-crazy pony into a drooling mess. Soon, her legs and arms plumped up as well, gaining a thick heft that caused her leggings to stretch out around the sudden tightness they were having to hold. Her weight gain even started to affect her regal face, turning it from that of an angular diva into a double-chin sporting glutton, "So delicious!" She muttered while dumping an entire bag full of daffodils into her mouth.

Her binge interrupted when she felt a building pressure suddenly release itself from her stomach. The belt around her waist suddenly broke, sending metal pieces raining across the floor of her kitchen. Rarity stopped her eating, seeing the pieces before turning back to the table and the decimated remainder of crumbs and scraps before her. She blinked a few times before she got to her hooves and looked down at herself and her much heavier frame that had seemingly swallowed up her previously small one. Silence pervaded the kitchen of Carousel Boutique for a short time before the now girthy garment maker let out a shrill scream at her current bodily state. She immediately rushed upstairs to her bathroom, having to hold up her skirt to keep it from falling down in her rush and made harder by how much her belly and breasts jiggled. She yanked her bathroom scale out and immediately put both hooves on it. To her utter shock, the dial turned to reveal her weight had climbed to 250 pounds, a very big change from the previously trim 130 she had been.

“Oh my stars, I’ve eaten myself into a...into...I don’t know! A marshmallow I suppose?!” She sputtered, owing to a joke Rainbow had made once in reference to her fur color. She stepped off the scale and ran into her bedroom to use the full-length mirror inside to get a full view at her newly developed shape. She put both hands underneath her chest to feel the heft of each individual blubber filled breast while sucking in her stomach (which to her dismay didn't go far before it immediately protruded out when she let out her breath.) Rarity turned around, looking over her shoulder at the most prominent feature of her growth: her rear end. It had developed into a thick, jelloey shelf of pure adipose propped up by wide hips and thighs thick enough to cover a pony's head if she put them together. Upon seeing the sight, Rarity winced at it while moving closer and turning around to feel underneath the round cheeks and second chin present on her face, “How could I have let myself become like this?” She groaned upon poking the side of her face and seeing it have some give against her finger, “I look like I’ve been stung by a group of bees!” She lamented while turning around again, “This will take months to work off!” Another pause came as she peered a little closer, swaying her hips around and making her purple tail shake, “Unless...I don’t work it off. That would be so much effort to try and do it, and it would certainly take away all the time from eating.” She immediately slapped her hand over her mouth, her eyes shrinking to dots from hearing what she had just said.

“That spell! The spell I cast to make me hungry to eat that cake must’ve done this! It’s turning me into an obese glutton that wants to get fatter! I have to fix this!” Rarity thought as she started to run over to the bookshelf. However, she stopped when her stomach snarled at her, indicating its apparent desire to be filled yet again. Knowing she’d never be able to concentrate with that going on, she sighed and opened up a hidden drawer in her wardrobe with a box labeled ‘Rarity’s Stress Cache’ that contained chocolate within it, taking out a bar and munching into it.

Unknown to her, the tipping point of her current situation.

“Mmmm, heavenly relief~” She sat back down on her bed (that creaked from having to hold up twice as much pony as it was used to) and moaned as the sweet, succulent taste washed over tongue. The more she ate, however, the more she found she couldn’t stop, not just from hunger but wanting the feeling to continue, “Ohhhhhh~” She panted, one of her chubby hands slipping down in between her legs. As she teased her marehood, though, she found there was a slight wetness underneath her skirt.

“Oh, Celestia...I’m actually getting aroused from eating now!” She realized, to her horror, “I must get to the book before this gets any worse...I must fix this.

I must lose weight...I must…”

Rarity moaned as she shoved the rest of the chocolate bar into her mouth, one of her digits tracing around her labia while she did so. Another bar came out of the cache as her eyes performed the same swirling effect they had when this whole situation was started. The part of her mind that was telling her to fix the “problem” became less urgent; a slight whisper instead of a desperate call to action like it had been. All senses of that were buried amid the arousing desire of eating and getting fatter...until it finally silenced.

The old, thin Rarity was gone.

The new, fat Rarity was here to stay.

“I must gain weight! I need more!” She hopped up and started wolfing down the entirety of the chocolate stockpile, “My lovely flanks must grow! I have to surpass the attention Pinkie Pie gets from hers!” She shouted, causing Opal to walk into the room with a very confused expression at the sudden change in personality the pony had experienced. The cat watched as Rarity sat on the floor, greedily stuffing chocolate after chocolate into her mouth. Truffles, bars, even little blocks of fudge all went down into her belly as her body kept blowing up with even more fat. Her waistline continued to vanish underneath her back and stomach rolls while her butt kept up the pace as her curves turned into highways with how large they were getting. Small tears started to form in her top, the fabric around her skirt stretched and hot, white fat emerged from holes in her leggings as the thin material found it harder and harder to contain the growling heaviness. As the stash had come and gone, she quickly stood up and passed by the mirror on her way back downstairs stopping and finding herself unable to take her eyes off herself. She was drop dead gorgeous and only getting more sexy with each pound she put on. There was one thing she disliked about her current appearance, however.

“These were my skinny clothes and they obviously can’t fit me. What better way than to rip them apart with my attractive, growing body?” She thought, grinning brightly as she left her bedroom, heavy hoof-falls coming as she entered the kitchen. She reached into her pantry, fridge and even her secondary emergency chocolate stash and pulled everything out that she could in an utter frenzy. If it was edible, she ate it and moaned louder with each bite and swallow. Just like before, of course, her frame continued to expand and grow heavier. Her belly exposed itself from between her skirt and shirt as it began to droop lower, her breasts actually ended up slipping out and leaving them exposed (erect nipples and all) while her developing back end made extremely quick work of the skirt as it snapped off finally, leaving her in a simple pair of black panties. The rips in her leggings got larger and larger, resembling vanilla frosting oozing out of a pastry bag that had holes in it. The ripping and tearing got louder in the kitchen as seams were tested and pushed to their absolute breaking point as the symphony was joined by a duet of furious eating and newly formed folds of blubber slapping and jiggling against each other.

“More...more!” Rarity said with absolute delight, “Grow, my fattening body! Swell, my lovely belly! Tear these inferior clothes to bits, cover them with fat, make me bigger!” She quickly said in between bites. Finally, her top ripped apart and fell to the ground in aqua silk pieces while her leggings finally gave way to a wave of flesh as the definition between her knees became swallowed up. Even her delicate fingers rounded into plump little digits dotted by purple nail polish. More moans and grunts came from her as she ate while rubbing her body. Her enormous ass stretched her underwear into a tight thong as it got swallowed up before it too succumbed and snapped apart, falling to the ground below her. A final, loud moan came as Rarity’s naked body shook from the utterly orgasmic feeling of her clothes being destroyed by the glorious, heavy fat she now possessed.

“Ahhh...oh my...oh dear.” Rarity gasped, taking deep breaths while patting her titanic tummy, “This is fantastic. I should’ve done this years ago.” She panted, plopping down into a chair (which also moaned in utter pain at the 400 pounds of pony coming down on it.) She looked around at the utter devastation of food around her coupled with the shreds of clothing laying at her hooves, some slight sweat dripping down her bloated face. While she felt good, she knew it wouldn’t be long before she’d be hungry again. The issue, though, was that she'd effectively cleared out the entirety of food from her home.

“Time to call every delivery place in town!” She thought, a light gasp of pleasure coming from her just thinking about all the food she was about to get.

**

“So, anypony sure ‘bout exactly why we all got called out ta here?” Applejack asked, arms crossed as she leaned against a wall, “Other than Rarity askin’ us ta come after havin’ not been seen in a week?”

“I don’t know, I just hope that she’s okay. It’s not like her to be this reclusive.” Fluttershy commented, worry on her face.

“Eh, I think she’s fine. She probably just got into a big project and just wanted some alone time.” Rainbow Dash shrugged as she floated above the other four ponies, “Would probably explain all the takeout boxes we saw out front.”

“Pinkie Pie, did she say anything when you saw her last week?” Twilight Sparkle looked over at the pink pony sitting on one of the tables nearby.

“Nope! She just took my measurements and that was that.” Pinkie shook her head, “Well, she did get a little blushy while she was doing it, though. That might’ve meant something.”

“Blushy?” The purple alicorn cocked an eyebrow. Before the question could be further explored, a tremor came from upstairs. All five eyes turned in different directions trying to find the source of the shaking. Eventually, they all turned toward the doorway as their eyes opened wide and their jaws dropped upon seeing the apparent source.

“Hello there, girls!” Rarity waved as she waddled into the room, panting as she tossed an apple fritter into her mouth from the plate floating next to her. In the time since she first started gaining, she’d grown exponentially. Her face had an additional chin bulging from underneath it with a thick necktire of fat propped up under that with a pair of heavily round cheeks to match. Both her arms and legs were mounds of flab dotted by her hands and hooves that were essentially sticking out of tubes of fat. In a feeble attempt at modesty, Rarity’s enormous breasts had red silk wrapped around them to try and at least cover herself while the megasized mammaries themselves rested atop her monster apron of a belly that was mere inches from the floor and quivered like a jar of jam with each breath or move the titanic tailoress made (and was completely exposed as Rarity felt no need to wear a bottom when her belly would simply obscure her privates.) The thing that made everypony in the room do a double take, though, was the colossal caboose she sported behind her. It was a miracle she could even fit through the doorway with it being so wide and quivering just as much as her gut. Both ass cheeks were like an avalanche of blubbery white mounds that divided into further rolls, completely dominating everything else on her backside. As she looked at all of them with a bright smile, she popped another fritter into her mouth and quickly ate it, “Well now, don’t everypony talk at once.” She joked.

“R-Rarity?!” Applejack guffawed, the tall and muscular earth pony shook her head to make sure her eyes weren’t playing tricks on her.

“Are you sure that’s her? It might be an impostor that ate her!” Rainbow said, laughing with a sarcastic smirk the athletically toned flyer had on most of the time.

“Oh my.” Fluttershy put a hand to her mouth, the lithe and meek pegasus trying to process what she had just seen.

“What in Equestria happened to you? Are you okay?” Twilight stepped forward, the average-sized princess looking her over.

“I’m perfectly fine, my dear. In fact, I’ve never felt better!” Rarity responded as she shoved two more fritters into her mouth, eating loudly before going back to speaking, “I was playing around with some magic last week and, well, afterwards I came to a revelation that I’ve been selling myself short this whole time. New experiences are what makes the world, and my waistline for that matter, go round!” She giggled, “Which is why I’ve brought you all here to announce a new formation within my line of clothing!” She threw a chunky hand into the air, “Rarity’s Ravishing Regalia! Clothing designed to fit Big Beautiful Mares and Big Beautiful Stallions!” She proudly declared, chomping down on another fried apple pastry as she did.

“Psh, she’s gotta’ be more like a SSBBM if ya’ ask me.” Rainbow chuckled, nudging Applejack in the side.

“Now how in tarnation do y’all know that term?” Applejack side-eyed Rainbow, the chromatic speedster’s eyes widening before she turned and looked away from AJ, nonchalantly whistling.

“I like it!” Pinkie Pie rushed up to Rarity and gave her as much of a hug as her chubby arms could allow, “You’re so cuddly and squishy!” She beamed bright as her snout nuzzled into the soft white fur.

“If this was caused by magic, there has to be a way for me to fix this. There’s no way this is healthy for you, Rarity.” Twilight pleaded, her tone completely matter-of-fact mixed with great concern.

“Oh, you needn’t worry about it, my dear.” Rarity waved off the suggestion, “I already looked things up and the initial faux pas was powerful enough that it’s practically irreversible now.” She said while eating the last of the fritters on the plate, “Mmmmmf,” she swallowed them and then looked over at Twilight, “Besides, I’m having the time of my life! Obviously, I’ll need to make some new clothes soon but the joys of eating are so wonderful to behold!”

An annoyed snort came from the princess as she folded her arms, “Well, that’s all well and good. But I would still like to at least know what spell it was you actually used.” Upon the statement, Rarity surveyed all her friends. First, she looked over at Pinkie Pie, the initial source of her jealousy that made her want to get the body she now possessed. Then to Fluttershy, skinny as a rail and wearing baggy, loose clothing. She then turner to the duo of AJ and Rainbow, both of which were currently talking about the situation and the contrast of athletics and raw strength on display with both their bodies. Finally, she came back to Twilight, the scholarly mare relatively small but possessing a slight belly from the mildly sedentary lifestyle she led (not much exercise was involved in book reading and research, after all.) It was then a thought dawned on her.

“Why should I be the only one to enjoy this lovely paradise I’ve run across?” It was then she turned and locked eyes with Twilight, a light laugh coming from her as a deep grin crossed her lips.

“Let me show you~” Rarity said softly, her horn flickering with light.
