Author's Note

A written commission for Anon.

Rainbow Dash is kidnapped by Pinkie, and is fattened to the extreme. This one is a little dark and a little gloomy.

Rainbow Dash

Rainbow Dash woke with a groan, blinking her eyes open. Shaking her head to clear the fog there, trying to move and stretch as she always did after a nap, Rainbow realized she had a problem.

She couldn’t move. She usually slept on her back, or on her stomach, but now she was laying on her right side. Soft pillows under her, with a blanket laying along her back. But she couldn’t move.

Why? Because she was chained to the soft bed. A harness trapping her wings close to her sides. Her hooves were chained to the top and bottom, with only a little give. And another chain running across her torso.

With every little movement they jangled, and with every movement Rainbow became more panicked. Realizing she truly, honestly, couldn’t move, she began to thrash. “Help! Hello!? Help me!”

A door opening stalled Rainbow in her tracks, lifting her head up to crane around in an attempt to see. She was underground, maybe, or just in an interior room with no windows. Fairly bare, it looked like a fairly average room in Ponyville. Nondescript, if cheerful, paintings on the wall, a few tables, a chair. Nothing too out of the ordinary.

Rainbow couldn’t see the door though, so when a familiar pink pony entered her line of sight she had to take a deep breath. Thrashing all the more in her bindings, “Pinkie!? Oh thank Celestia, you gotta help me get out of here!”

“Oh silly! How did you think you got here?” Pinkie grinned, her chubby cheeks dimpling with the fierceness of the smiles. “Please stop squirming, I don’t want you to hurt yourself Dashie!”

Rainbow did stop, a fierce frown on her face. Panting, “What’s going on!?”

“Well, you know how you said my demands were getting too much? That you couldn’t eat all the things I wanted you to, even though you wanted to be my feedee?”

Having it stated out in the open like that, with no pretence, made Rainbow blush fiercely. She’d...well after that injury last year, she hadn’t been able to be a Wonderbolt anymore. She’d tried a lot in an effort to fill the hole in her life, unable to do what she’d dreamed of. Food had filled the hole well enough, and what had initially been something of a hobby, quickly became an obsession.

Pinkie had been one of the bigger helps, of course. With her working at Sugarcube Corner, her connections with the culinary community, it just made sense.

When the inevitable effects started to appear, Rainbow had initially panicked. Not because she’d gained weight, that seemed more Rarity’s style, but because she’d enjoyed it. She’d enjoyed the gain. Enjoyed the little bit of softness that appeared.

It was shortly after that, that Rainbow had discovered feederism, and had asked Pinkie to be her feeder.

Rainbow had tried to be a good feedee, honest. But Pinkie had all sorts of crazy demands right from the get go that left Rainbow Dash feeling sick more often than not. Even with the scales starting to tip, it had been too much too quickly. So Rainbow had called it off.

“Well...yeah?” Rainbow’s head quirked to one side. “What’s going on, Pinkie?”

“Well, I decided I couldn’t accept your answer!” Pinkie was as bubbly as ever. The pink party pony bouncing in place. She wasn’t fat, but her work had left some pudge on her body. It was her exuberance and activity that burned most of it off, of course, but it was still noticeable.

“What?”

“I said I can’t accept that answer.” Pinkie repeated, with just as much cheer. “Now, come on. Be a good feedee and eat for Pinkie!”

Rainbow had opened her mouth to say something, start screaming, something, but a hose dropped from the ceiling and Pinkie shoved it into Rainbow’s mouth. Attaching it with some sort of strap around the back of her head.

Pinkie playfully tapped Rainbow’s cheek, purposefully feeling the new layer of fat there. Still, her grin didn’t move, “Eat up, you must be starving.” Moving back, and audibly pressing a button of some kind. Ignoring Rainbow as the mare started up her struggles again.

The struggling didn’t last long, not when her wing started aching and sweat beaded across her body. She wasn’t fat, not yet, just chubby. But her lack of exercise routine had meant her muscle had been atrophying away. There just wasn’t a way for Rainbow to get out, not in her state.

It didn’t take long for a thick, creamy liquid to start pouring into Rainbow’s mouth. Making her gulp and drink it down quickly so she didn’t drown. Working hard, even as her stomach began to bloat out and ache as it was rapidly pumped full of the sugary, rich liquid.

Rainbow couldn’t help but moan and groan as the force feeding continued. Tears starting to run down her face as she went from full, to so full it hurt. And still, she was forced to drink. Her stomach churning, bloated, aching so bad it felt like it would burst. And still she drank on.

It wasn’t until Rainbow genuinely thought her stomach would burst that the feeding stopped. Leaving her to groan, moan, and whimper around the tube as the agony set in. Nausea set in shortly after, but Rainbow was stubborn and prideful. She swallowed convulsively, whimpering as every small motion she managed sent shards of glass through her distended stomach. She couldn’t even see the chub on it now, it was so bloated.

She looked pregnant, and it hurt.

“There! Not so bad, is it?” Pinkie crooned. “Told you it wouldn’t be so bad. How about you rest up, and Pinkie will go and make sure you don’t ever have to worry about food again. Okay?”

Rainbow couldn’t answer, but she watched with terror and agony as Pinkie sauntered out of her line of sight, and a door shut.

What’s going to happen to me?

(LINE BREAK)

It was impossible to tell time here. There were no windows, no clocks. And with Rainbow being positioned the way she was, she couldn’t even see the door out of the room. It was possible there was a window right there, and she’d never know.

It could have been weeks, might have been months. It felt like a long time, but who was Rainbow to know? All she knew was feedings, pain, Pinkie, and Fat. Sometimes she was fed with the tube, often with the tube, but sometimes it would be replaced with a feedbag that was enchanted in some way.

Always, Rainbow was stuffed to bursting. She had the feeling that Pinkie managed to use the tubes at night, as well, since she could sleep for...well, a long time, and still wake up full. But once more: who was Rainbow to know for certain.

She couldn’t tell what was worse: the feedbag or the tubes. She couldn’t speak with either on, but at least the feedbag never made her feel she was going to drown…

The door opened, and Rainbow instinctively stiffened. She was hooked up to the feedbag now, eating pie.

Rainbow had never gotten around to telling Pinkie how much she hated pie (all pie), and now she never would. Her mouth opened and took a mouthful without provocation, making her savour the lemon meringue even as she wanted to get it out of her mouth by any means necessary.

“Oh, Rainbow, you sure are growing.” A hoof ran along Rainbow’s flank as Pinkie wound her way around the bed to be in Rainbow’s line of sight. Wearing her usual smile, the baker prodded a little deeper. Her hoof sinking into Rainbow’s blubbery flanks with little resistance.

Trapped here, strapped down. Burning almost no calories, Rainbow was starting to bubble up like a bread pan with too much dough inside. Piling on the pounds in speeds that fascinated and sickened her. As the chain around her torso grew tighter with every passing...day, it was evident that nothing of the once athletic pegasus was being spared the onslaught of calories.

“Here, how about some water. You must be thirsty.” Pinkie produced a tall glass of ice water from nowhere, undoing the feedbag. Letting Rainbow use the straw greedily, gulping down the cold liquid like the precious treasure it was. “You know, you really should learn to control yourself Rainbow. You keep piling on more weight, and I’ll have to get some longer chains.

In spite of herself, heat rose to Rainbow’s face at the teasing. This was sometimes the worst part of her captivity, the teasing. It hurt to know such a close friend was doing this to her.

“Well, it’s alright. I don’t mind getting longer chains...though I wonder how much food I’d have to stuff you with before your burst out of it.” Pinkie reached a hoof over to press against the chain, and Rainbow’s stomach.

As always, Rainbow’s stomach was full to bursting. So the additional pressure hurt. A belch escaped the pegasus, even as Pinkie kept rubbing it.

There was no mirror, so it was hard to gauge her size, but Rainbow could feel her wobbly flank raising into the air, feel the trapped one squishing below her. Her flabby stomach was now so flabby it was no longer obvious how painfully full she was. She could feel her chubby cheeks sagging, an extra chin and jowls rubbing together. Her neck felt heavier, softer. Her pigeon chest squishing between her front legs, shoulder fat loose and twitchy whenever her muscles twitched.

Her barrel must be wide too, and Celestia only knew about her wings-

“Oh don’t worry, Dashie, I’ll make sure you’re too fat to fly too. That harness can’t be comfortable, so I’ll be sure to take it off once I’m sure you can’t try to escape.”

Part of Dash wanted to store water in her cheeks and spit it out at Pinkie, but the last time she’d tried that, she hadn’t gotten water in a long time. Being served sugary juices and things instead. It had been repetitive after a while, so Rainbow wasn’t keen on the same punishment again.

“You’re still so thin.” Pinkie tutted, shaking her head, “but don’t worry. I’ll fix it for you. We can’t have you trying to run off after all.” Taking the cup away once it was empty, and reattaching the feedbag.

She left as the enchantment took hold, making Rainbow once again gorge herself on pie that she hated. While Rainbow was left to cry and gag over the food, trying to once again wriggle her way to freedom, even as she knew it wouldn’t be enough.

(LINEBREAK)

Rainbow hated the sight before her, hated it so much that rage was sitting, waiting in the back of her throat. Waiting for some sort of release, be it screaming or crying or some unholy mixture of both.

She’d outgrown the third set of chains around her torso, and with that, Pinkie had declared her captive fat enough that she wouldn’t be able to get out. Using a pully system to pry the fattened pegasus from her side, and onto her stomach.

It would have been unbearable agony at the start, but there was a lot of cushion between the sensitive, overstretched organ and the bed now. So much so that, even as it ached and churned, it didn’t hurt all that much more to be laying like this. Facing a painting of the ocean, Rainbow still couldn’t see the door, but at leas she was somewhat upright.

At least, she’d been happy about this small thing. Until Pinkie had laboriously moved the bed so Rainbow was facing the same wall as before. Which was a surprise, because Rainbow hadn’t thought the bed was on wheels, but it was.

There was a mirror there now, making Rainbow stare at the blob of a mare she’d become. She was still chained to the bed, but the harness and the chain around her torso were both gone. She was now ‘too fat to fly’ as Pinkie had so often put it.

And Pinkie wasn’t wrong, not if what the mirror was showing was any indication.

Rainbow wriggled a hoof, sending thick waves through her body. The motion evident in how her fat moved, but also present in the mirror.

Rainbow cried as the tubes started to pump the thick milkshake into her maw once more. The straps lightened and stained by all the tears she was crying into them. They were tight now, making her chubby chins look all the fatter for it.

Rainbow’s stomach was her largest feature. Pooling underneath her like a second mattress, it touched the edges of the actual mattress and threatened to roll over them. Even if she could get off the bed and onto the floor, she wouldn’t go anywhere, her stomach was so large now that her hooves were lifted off the ground.

As if that weren’t enough, the rest of her seemed just as large. Just small in comparison to her stomach. Her flanks were large, her cutie marks stretched out and faded. Her plot overhanging her hocks and rolling over her knees. Her lower limbs, once so slender, had a firm layer of fat that rolled over at the ankles, making her hooves look smaller than they had a right to be.

Rainbow’s wings, once her pride and joy, looked more like feathery pillows strapped to her sides. Half buried in the fat of her back and barrel, she could hardly see them. Let alone move them. Fat had collected along their joints, making it impossible for her to flap them.

Her neck was gone, replaced by several thick, meaty rolls that hung down as extra chins when Rainbow looked at her face. The rolls were the only indication she’d had a neck, and even then they hung to merge with her flabby chest.

Rainbow’s face was near spherical it was filled with so much fat. Big poofy cheeks, sagging jowls, a number of extra chins...There was no denying how fat she was. Not anymore.

“There, that’s better isn’t it?” Pinkie grinned. Rubbing a hoof along Rainbow’s side. She reached around to undo the straps once the milkshake stopped pumping, offering Rainbow some water.

“Am-am I big enough now?” Rainbow asked hesitantly before she began to drink. Her voice was a hoarse croak from disuse.

Pinkie giggled, but kept quiet until Rainbow had finished. She leaned in real close and booped the tip of Rainbow’s nose, “Nope!” Then reattached the hose. All but skipping from the room.

Leaving Rainbow to her misery, staring at a pony she could no longer reconcile as herself.

(LINE BREAK)

Every time Rainbow awoke, she was forced to see how much bigger she’d gotten. Even as her stomach rolled over the edges of the mattress, tugging down on her. Even as her hind legs became increasingly trapped between her fatty plot and flabby stomach.

The chains had been removed once Pinkie made Rainbow try to raise her front legs above her head. The fat of her shoulder was thick enough now that it blocked her movement. Her front legs just...resting there, unable to lay flat because of all the fat. Spread wide to make room for her flabby, sagging chest.

Her hind legs hadn’t done much better. Unable to free themselves from between her stomach and plot, she could just about wriggle the ankle, but any other movement was beyond her.

Rainbow hated this. Hated Pinkie for doing this to her. Hated her friends, because somehow they hadn’t found her or rescued her yet. Hated herself.for every single calorie she managed to put into her stretched stomach.

If Rainbow could stand, which by now was just an impossibility, there’d be know way she’d have gotten out. Her muscles, already atrophying by the time Pinkie captured her, were all but withered away now. Spared even the most basic forms of exercise, whenever Rainbow bothered trying to move, it wasn’t long before aching muscles forced her to stop. Out of shape, out of breath, and out of hope, Rainbow started crying more. Hating what she saw in the mirror all the more, day after day.

“Rainbow?”

Whispered, hurried. A hoof jostled her shoulder harshly, sending waves throughout the pegasus’ fat body. Hard enough that it jolted Rainbow from her sleep.

The noise she made when she woke up was indistinct because of the tubing. Blinking dried tears from her eyes, Rainbow’s eyes met the mirror, and she couldn’t believe what was going on.

Twilight was here. Twilight was here, and she was going to help, and Rainbow would be free!

Rainbow tried talking about the tube for the first time in months, muffled and indistinct and not at all making much sense. The bed creaking and groaning under her weight as she utilized the most of her mobility and tried to wiggle with excitement.

Twilight’s magic unhooked the tubes, and Rainbow opened her mouth to let out the flood of words that were just waiting to escape her, only to be cut off.

By a large slice of cake being jammed into her mouth by Twilight’s magic. Rainbow almost choked on it, it was so unexpected. But instincts honed by Pinkie kicked in, and Rainbow started eating.

The excitement balloon popped, deflating Rainbow Dash with the quickness of air escaping a tractor tire that was more hole than tire. With each piece of cake, or eclair, or whatever else Twilight was all but ramming down Rainbow’s throat, the excitement and relief turned into horror and anger.

Still, Rainbow ate on. Not knowing what sorts of punishments that Twilight would use, and not wanting to risk her wrath if she refused the sweets.

With every mouthful, Rainbow hated it all the more. Hated her friends, hated this situation, hated her broken wing, hated herself. If she hadn’t broken her wing, she’d still be flying. None of this would have happened, and she’d be free to soar the sky as she pleased.

It was a good fantasy. Remembering to fly. Even as Rainbow began to cry at the amount of food being shoved into her, her already full stomach starting to ache and bloat out even more with every new item that joined with the rest of its contents.

(LINE BREAK)

Twilight became a regular fixture from then on out. Feeding her casting spells. But doing so in near perfect silence, unlike Pinkie who would constantly talk and tease.

It wasn’t long before Rainbow realized that she was gaining weight even quicker now. Not when the bed, which was large enough to hold two or three average sized ponies on it, was completely eclipsed by her fat.

Not when the frame was crushed under her weight, sending her to the floor.

Not when Rainbow quickly outgrew the remains of the bed, and Pinkie and Twilight started removing furniture.

Rainbow opened her eyes to find that the mirror had been moved, and she didn’t know why. Panting, wheezing weakly, she tried to turn her head to see what was going on, but even that little freedom was starting to become impossible with all the fat around the joints.

Rainbow did her best to wiggle a little, her fat jostling for meters all around her, and then-

It was hard to tell, for Rainbow at least. But she was sure she could feel all sides of the room with her fat alone. Could feel her stomach press against the crack under the doorway, looking for extra room.

The tears were almost automatic now, like eating or breathing or blinking. The tears flowing down Rainbow’s fatty cheek as the tubing started to pour milkshake into her stomach once more.

Rainbow closed her eyes, squeezing them shut. Mind scrambling for anything, anything different-

Flying. Flying is what she turned back to. She dreamed of flying through clouds, feeling the wind move along her wings, feeling her heart racing in her chest as she performed stunts above cheering crowds.

It wasn’t much, but the fantasies were all Rainbow had. They gave her a glimmer of hope to cling to, even though her life was already in shambles.

As deep in this fantasy as she was, Rainbow ignored the odd taste on her tongue. The milkshake flavours changed often, just like the other things she was being fed, so maybe it was just...just a new-new flavour…

Her eyes were already closed, so Rainbow wasn’t even aware that she was falling asleep.

When she next woke up, it was different. A larger room. With tightly drawn curtains and no furniture, Rainbow was amazed to realize that her fat was no longer being pinched by the walls.

The relief didn’t last long, not when the milkshake started up again, even though her stomach was still packed to the point of pain.

At this rate, the pain was a normal, welcome sensation. One of the few Rainbow ever felt anymore.

The tears started up again, further staining the straps around her face.

“Oh, don’t worry Dashie,” Pinkie pouted, reaching over to pet a part of Rainbow’s mattress of a stomach, “Don’t you worry, just cuz you outgrew your old room doesn’t mean we’re going to stop. You’re not nearly large enough yet.”

The only thing that kept Rainbow from sobbing was the tubing in her mouth. She squeezed her eyes shut, still crying, and thought of wind rustling through her mane.

Pinkie continued to pet the roll of fat, stuffing Rainbow so full that Rainbow passed out well before the feeding was finished.

(LINE BREAK)

A new routine was organized, one where there was almost no times between feedings. The tubes were swapped for the feedbag, which made Rainbow eat a mouthful every so often to keep her gut stuffed full of whatever food was the flavour of the day.

It ranged from sugary, sweet desserts to full meals. It changed on a whim, probably Pinkie’s. The savoury foods were something that Rainbow grew to look forward to, as sad as it was.

Twilight’s visits were longer, stretching out across days and weeks rather than just single days.

There was still no mirror, but it didn’t surprise Rainbow when her flabby sides once again touched the sides of the room.

What was a surprise, though, was feeling the top of her plot touching what could only be the ceiling.

By this time, any ability beyond chewing was impossible for the immobilized pegasus. She couldn’t even twitch a muscle anymore, they were so atrophied behind her bulging figure.

Unbeknownst to Rainbow, she didn’t resemble a pony so much as she did a blob. Her hooves were swallowed up by the heavy sleeves of fat where her legs had once been. Her wings were unrecognizable as such, the feathers broken and bent. They looked like flabby cushions half submerged in the squishy, meters thick fat that clung to her barrel. Her tail was swallowed up by her plot, trapped between the massive cheeks.

Rainbow didn’t need to hold her head up anymore. The fatty rolls that indicated where her neck might have been was doing the work for her. So large and fatty that they created enough cushion for her to relax. Just a series of tires of fat with her face and head in the middle.

Her head was starting to be encapsulated in the fat of her neck, making it appear it was sinking into a sleeve much like her hooves long before.

Her forehead fat was beginning to droop down, and with her fatty cheeks growing with every pound, Rainbow’s vision was starting to get impaired, made even worse considering the feedbag and the tubing.

It didn’t take long after that for Rainbow to be moved again.

This time though, Rainbow was thrilled to realize she was outside! For the first time in what felt like eons she was outside, with the breeze on her skin and the scent of summer flowers on the wind-

Yet she was still hooked up to the feed bag. And now she was outside, she could see ponies gawking at her.

In spite of her aching, fit-to-burst stomach, she took a bite of the sweet ice cream she was being fed today. Why not give them a show? The only thing that Rainbow could do by now was eat? So why not give the assembled crowd something to watch?

Her stomach churned all the more, groaning and grumbling enough to send rippled through her form. Rainbow didn’t care, or really notice the searing pain in her stomach. Taking another bite, and another. And another.

Obviously there was no hope for escape. It was foolish to think it, even for a split second.

Rainbow gorged herself into sleep this time. Purposefully ignoring the comments and whispers from the ponies that had gathered to view her enormity.

(LINE BREAK)

The worst thing about being outside, was that Rainbow was suddenly surrounded by frames of reference.

She was too big for a house, for one. Which was why she was moved out here. She was now so fat, with her stomach pooling under her to push her up, that she could just about peer over the roof of the nearest building.

Pinkie climbed all over her, chatting and petting. Sometimes, she’d fall asleep on one of the larger rolls. Reminding Rainbow fiercely of how she used to nap on clouds.

It was just a reminder of how big she was, really. To have a full grown pony able to pick a spot and sleep on one of the many rolls and folds that made up Rainbow’s body.

The flavour today was chocolate cake, and it hurt to hear Pinkie snoring. At least it helped dim the whispers a bit.

Which...speaking of, there were fewer ponies here than there had been. For weeks and weeks, now.

And, the town didn’t seem as loud as she remembered. Less traffic, fewer ponies...What was going on?

Rainbow ate a few mouthfuls of cake, trying her best to see around the fat of her face to figure out what exactly was going on-

“You know,” Pinkie’s voice was right by her ear, making Rainbow stop mid-chew. “You’re still not big enough.”

Fear lanced through Rainbow’s body, and the tears started to flow again. Even as she chewed the thick, chocolatey cake, Pinkie was stroking one of her cheeks.

“I thought you’d be happier out here Dashie, outside. You always did like it out here. Are you happier?”

Rainbow couldn’t help but groan as the bite of chocolate cake hit her stomach.

Pinkie continued to knead at Rainbow’s fat. “Oh good! I’m so glad. I know you’re almost as big as a house, which honestly was a big goal of mine...but I keep looking at you, and I think you can be bigger than all of Ponyville with just a little more work. Twilight’s been helping, she knows all sorts of spells. It won’t be long, I don’t think. Just a few more months, and you’ll be bigger than a whole town! Isn’t that exciting!?”

Rainbow couldn’t help the sob that escaped her, though the sound was muffled. If she could move, she might have tried to wiggle in displeasure, but that was long since doable.

“Oh don’t worry Dashie!” Pinkie beamed, still kneading, “It’ll be fun! Don’t you worry, we’ll have a great time!”

(LINE BREAK)

Rainbow was, potentially, the largest pony in Equestria. Was the largest, heaviest mare in the history of the continent, as far as Rainbow was concerned. She’d set world records, several times over.

And now, she was large enough to encapsulate all the land that had once been Ponyville. So large she resembled nothing living, just...piles and piles of cyan fat that had once been a pony. A formless blob, it was hard to look at her and remember there was a pony buried underneath the thousands and thousands of pounds that occluded her frame.

And still, Rainbow was eating. Ignoring the whirring contraption that Pinkie used to help her scale Rainbow’s fatty sides, she could just eat from the feedbag and live in her fantasy world. Pretend she could breath normally, seen normally, that her head wasn’t being sucked into her neck fat.

Rainbow was just...indescribably huge, and she felt it. Even as Pinkie poked and prodded, bouncing around in the soft rolls of Rainbow’s neck.

Giggling, still bouncing, Pinkie made her way closer. “You did it, Dashie! Bigger than Ponyville! I’m so proud of you!” Unhooking the feedbag, “It’s time for your surprise!”

The tubing was lowered to her mouth. She hadn’t seen it in...months? Years? It was hard to say when all her days blended together. Her mouth opened automatically, yet Pinkie didn’t stop to strap it in place.

The milkshake, after such a long time without it, was refreshing. And Rainbow couldn’t help but gulp it down eagerly, even though she was already fit to burst.

It was hard to say how long she drank for, but by the time there was a soft hissing sound, and the flood stopped, Rainbow was once again full to the point of agony. Nausea churning her stomach, bile kissing the back of her throat. But she didn’t get this big by giving up, or losing her pride. So swallowed it down, panting.

“Good job, Dashie! I’m so proud!” Pinkie hugged one of Rainbows neck rolls.

“Big...enough?” Rainbow rasped, panting from the effort of speaking two words.

Pinkie leaned in real close, her grin never shifting. “Nope!” Booping Rainbow’s nuzzle to laugh loudly, reattaching the feedbag before Rainbow had any chance to retort.
