1. The Attraction

Down in a frosty ponyville, it had become one cold winter. All animals in sight had been plumped up and sent to hibernate. Rainbow Dash had just finished her job in the white misty heavens, filling up the sky with Cloudsdale’s freshest winter clouds. She was the fastest at the job, everyone had concluded. Her flying skill was ‘out of this world’; she would elegantly spin through the cold collecting clouds, glide through gale winds, and soar through burning sunshine. Whatever the weather, Dash always had a trick to amaze everyone. There was just one thought that knawed at her mind: Pinkie Pie.

Ever since the start of Winter, Pinkie had been isolating herself from the world, rarely seeing her friends. Every day she backed into the basement of Sugarcube Corner, locking the door behind her. And when she would finally reappear, her belly had become bigger and flabbier every time.

Rainbow Dash couldn't help but notice what Pinkie Pie had become. Her once slender, bouncy figure had slowed into an overweight blob of pink flab. Whenever she walked by, time appeared to slow down – either that or Pinkie simply walked slower – and Dash’s eyes were glued to the bouncing rolls of fat under her soft stomach.

Something pulled her towards it - an indescribable feeling. She would normally be concerned for her friend gaining so much weight and losing her agility; her cute little winter clothes getting tighter every day. Yet somehow, the longer she stared, the more she longed for what she saw.

Dash was disastrous at being discreet. Pinkie must have noticed those glaring eyes hundreds of times, yet she never spoke a word. So, to ‘clear the skies’ over it, Dash approached her. “I know animals need to fatten up for the winter and all, but-“

“Oh you mean my belllllly?” emphasised Pinkie, shaking her monster of a stomach around. “I’m not fat, I’m just cuddly you see! You need it when the winter is so freeezing collld! Anyway gotta go quickly now bye!” – Dash had no time to talk. What WAS Pinkie up to!? Dash pretty much knew already; locking herself in a basement and coming out bloated and bigger each time? Her private routine was becoming obvious.

Rainbow Dash watched Pinkie’s rolls jiggling from left to right, as she plodded into her infamous basement. She turned her head away abruptly, as Pinkie caught her eye - that felt awkward... It was as if... As if Pinkie knew she’d be looking. What was she planning? This new thrill was driving Dash crazy, and a dirty temptation was bugging her. She made a fateful decision to come alone and investigate at night...

2. A Fateful Visit

On that same buzzing late night, the temptation grew uncontrollably. Her urges shot higher than Pinkie Pie’s calorie intake. Rainbow Dash could no longer stop herself - she crept down to Sugarcube Corner, peering through the door. "Ooh, you're right on time Dashie!" triumphed an eager Pinkie Pie, looking prepared at the store entrance.

"What? She was expecting me?? Right at that second!?" she thought. But before Dash even had time to process what had just happened, her pink friend began to drag her across the floor. She took Dash’s slender, athletic legs by the hooves.

“Just let it happen, Dash; you know it's what you want...” Dash’s muscles relaxed, an unknown pleasure flowing through them.

What else stopped Rainbow from Dashing away? Oh... It was the sight of that... That apron! It was like PORN to Dash’s helpless eyes. The hills and bumps in Pinkie’s stomach were emphasised by the choking-tight fabric, which shaped and creased around every roll in her body. All Dash could do was stare at the gaining perfection, as Pinkie pulled her through the rather deserted dessert shop.

"Where are you taking me?" she hesitated - a cocktail of confusing emotions intoxicating her mind.

Pinkie whispered erotically, "I'm going to show you the plus side, to becoming plus size..."

An unknown force stopped her from flying away – Dash had a strong idea of the events that were to follow, and escaping this would be an easy feat. But regardless, she found herself still submitting to Pinkie’s plans... Through the next room, Dash was dragged into a sweet-smelling basement, every corner packed with pitch darkness – until the light was turned on, revealing Pinkie's fantasy-like food hoard. All around her were stacks of freshly iced cupcakes. The thick buttercream glistened divinely - it seemed to be designed, specially, to fatten up its victims.

Rainbow Dash relaxed onto a reclined black chair, and was submissively strapped into her gluttonous fate. Pinkie pulled the straps over, gently caressing her soft cyan skin. She attached the final strap below Dash’s stomach - making this one loose for obvious reasons. Her thin, athletic body shivered with adrenaline, and butterflies swarmed her unfed stomach. What was going to happen to her? Why did her friend gain so much weight? And most of all - why did allowing this feel so pleasing?

"I'm SO glad you came here!" gleamed Pinkie. "I baked all these beautiful cakes and... I really couldn't eat them all alone! I needed a friend like YOU! To indulge in the thick fattiness of the icing and the sugar and the sweet satisfying taste and - whoa that was a long sentence." She was out of breath. Maybe a quick cupcake would fix her low energy? Pinkie peeled off the small, delicate wrapper, and Rainbow watched as her teeth glided through the beautifully buttery icing. As Pinkie revelled in the food, Dash was in more awe than all of Ponyville watching her fly...

She felt disturbed by what her friend was doing, but somehow that disgust was arousing to her. Pinkie was doing this deliberately – doing what was socially frowned upon, on purpose... “Oh, my apron’s getting tight...” struggled Pinkie. She reached her hooves down her back, her compressed belly pushing and fighting forward. The apron came untied, and her exploding belly jiggled freely again. “There ya go!” - Pinkie crammed in the rest of the cake, whilst taking her time to process the buttery flavour. Dash's eyes widened at her hoof, rubbing her soft belly up and down as the cupcake entered her body. "Now it's YOUR turn Dashie!" whispered Pinkie in a seductive tone.

Dash said nothing. She was unable to speak, engulfed by her all-consuming thrill and excitement. The dread of gaining weight had receded to the back of her mind. It was late, she was tired, and her logical thinking had melted like butter. All that was left was her new inner fantasy, rapidly taking over.

3. Submitting to the Feeding

Pinkie proclaimed passionately, "Let's get fat. It can't just be me who's fat, we'll both be fat together, won't we Dash! We'll come down here in late hours and smother ourselves in cake, eating it until we pass out. And, since you seem to looove staring at my belly, I thought you’d love having your own to stare at too! When I'm not around, you could just look in the mirror! So wadd’ya say?” - As Pinkie leaned over, her soft fat pushed against Rainbow Dash. The warm, thick belly smothered out on top of her, and Dash began to envy the pudginess.

"FEED ME NOW", she helplessly blurted. A Freudian slip... She tried to shove a hoof in her mouth in shock, but the restricting chair kept her unable to move.

"That's what I wanna hear!" said Pinkie gleefully. "Here's the first cupcake. Extra fatty, sugary, BUTTERY icing, with luxurious sponge cake inside. 50 boxes of these will turn your Thunderbolt abilities into Thunder THIGHS! You’ll go from wearing flight clothes to tight clothes! Now open up!"

Dash opened wide, as Pinkie slid the first cupcake into her mouth. Leaning on top, she elegantly closed Dash’s mouth with her hoof. "Now enjoy..." she whispered. The fear of consequences began to race through Dash, but she couldn't stop herself. The seductive satisfaction rushed through her body, as the smooth icing squished against the sides of her mouth. Part of her felt it was so wrong; the cake was definitely full of fat and enough to ruin her flying ability. The cake's calorific effect was clearly evident on Pinkie’s own body – but Dash kept chewing. Pinkie's words felt chilling and sinister, yet they only sparked more tempting arousal...

"I know it's hard, Rainbow Dash. Sometimes you just have to let go; leave your flying days behind." Pinkie approached Dash’s already-open mouth with the next cupcake, sliding it in whole so Dash could no longer speak. "It might feel wrong at first, but you'll accept your growing belly. Just say goodbye to the Wonderbolts, and all the training you did for them, ‘cause you’re gonna grow into my big, chubby, cuddly friend!"

Rainbow Dash now felt even more scared and unnerved, but the arousal swallowed it whole - quicker than she could swallow Pinkie's cupcakes.

Dash imagined herself straining to fly, unable to do what she used to love doing. She pictured her belly bouncing around, the tight Wonderbolts' suit barely reaching halfway down her bulging body. Oh, how she wanted that figure. Huge rolls of fat tumbling down her build, and two suffocated wings sprouting through the thick folds in her back. All she had currently was a thin, streamlined shape, soon to fatten up into her new dream.

Pinkie Pie had full control over her slender, sky-blue friend. She dictated the destiny of Dash’s physique. Dash had no control over how large she was going to become, and this enticed her more. You could almost say she couldn’t 'weight' for it.

Pinkie was eager to ask, "When did you last perform a sonic rainboom?” Dash didn't want to speak; she needed to savour every second by eating efficiently.

"Last week", she mumbled, her mouth stuffed with creamy delight. She knew this rainboom was now the last she would ever perform, as her bloated stomach began digesting the cakes into fat. "I can feel the weight coming on already" she said with dirty satisfaction.

Her stomach grew with every delicious cake she ate; Dash went through chocolate, vanilla, blueberry, ‘banoffee‘- she couldn't even count the rest, not to mention counting the calories. All of it blurred into one indulgent sugary feast, fed to her by a pudgy pink princess. Or, to phrase it more accurately, a princess in Dash’s eyes. Her full, bloated stomach was nearly as big as Pinkie’s empty, flabby one, but she kept fighting the pain in her stretching belly. Every time she swallowed, another mouthful of cake stretched out her stomach and forced her body to process the fat.

“I know it hurts, Dash, but all growth hurts. The struggle will pay off in the end, and you will grow! You’ll get through these growing pains – I believe in you!” Pinkie comforted Dash, delicately placing a kiss on her cheek.

An army could demolish a chateau, but Dash was demolishing a gateau. Her stomach only gurgled and grumbled for more. The whole store's cake supply began to deplete, with every treat tightly crammed into Rainbow’s giant, growling belly. “Uggggh. I’m so full...” she moaned.

"Oh, sounds like your body strength is going to good use, Rainbow Dash! Instead of flying around, those strong muscles are breaking down all that cake! And soon, they'll be holding up your flabby ol' belly!" grinned a devious Pinkie. "But you don't want them to starrrve, burning energy on all that tough... digesting... WORK…" Pinkie tumbled on her back dramatically, her enormous belly wobbling around at the same time. Pinkie’s face dropped at the thought of burning calories.

Pinkie plodded through a plethora of empty cake boxes, eventually finding the fridge in the room's back corner. Opening the door, she lifted out a hefty gallon of thick, creamy milkshake. "Here, this'll help those tired muscles out! It’s my classic milkshake recipe, but with added butter and ice cream this time!"

Approaching the cyan mountain that was Rainbow Dash, she shoved a large feeding tube into her mouth. Pinkie stood on a tall chair, and began pouring the dense, gluttonous milkshake into the funnel. Rainbow closed her eyes as she sucked on the fattening elixir, the liquid swirling and spinning into her body. One could say this put the cherry on top of the ‘cake’... This was it. Her flying days were over. She would wake up the next morning with a towering, doughy stomach, anchoring her to the ground. Dash accepted it; the sky was no longer for her. The Wonderbolts would stop hanging out with her, and she would instead indulge in nightly feasts with her plump pink friend. THIS was for her... A life of wearing tight, plus-sized clothing that could still barely fit, and feeling her gaining perfection all day long.

The healthy past swashed away like the milkshake gulping down her throat, and her belly rumbled a moan of satisfaction. The sugar had filled her body with vibrant energy, but this time she wouldn't be burning it off. Soon her body would adapt to its new routine, and calories would turn straight into fat, instead of giving her the usual energy boost.

Dash remembered the previous day; all the fantastic stunts she had performed in front of her eager crowd. She flew to the rainbow and back, spinning and circling around like no other pony could. That was real talent. But, looking at her bloated stomach now, the future didn’t look so athletic. Strangely, these thoughts only turned Dash on. Transforming from thin to fat; agile to immobile. She pictured herself attempting to fly again, barely being able to lift a single inch from the ground. Someday her wings could be completely swallowed up by her fat rolls, and her legs unable to reach the ground due to the size of her belly. She imagined herself looking like an inflated balloon mascot, floating in a parade - this comparison only made her laugh. But laughing proved to be painful; it shook her rock-hard heap of a stomach, reminding her of how much food she had consumed.

"Now, I don't want you moving and burning any energy, so you'll be sleeping right where you are!" advised Pinkie – a sensible suggestion for a change. Rainbow Dash agreed and, letting her body digest the heavy load of calories, she slowly drifted off into her food-coma induced sleep.

Pinkie may not have eaten much, but that was okay; she had generously given the feast to a friend who really needed it. All night they dreamed of their amazing fantasy, and as they slept, Dash’s belly slowly transformed from solid and bloated to squishy and fat.

4. Glorious Gains

The next morning, Dash looked down to see her new coating of delicate, soft fat. "Looks like all that cake paid off!" proclaimed Dash, waking up Pinkie Pie.

Gaining consciousness, Pinkie slumped up and looked around. Her head stopped sharply as she saw her friend's new stomach, her face brightening in amazement. Dash’s belly had begun to hang over the straps of the chair; the fat stretched her skin and puffed out into a chubby, dome-shaped work of art. And at the summit of the mountain, the smooth fat pushed down a round crevasse, with a divinely deep drop into her belly button. "You look beautiful..." beamed an astonished Pinkie. Now that her friend was bigger, she was no longer alone in her gaining journey...

Pinkie Pie rolled sneakily into the kitchen on her doughball belly, taking some of the fresh pastries Mr and Mrs Cake had baked. Rainbow licked her lips at the delightful sight, her belly grumbling more than ever before. "I hope you like eating creamy, FATTENING cheese pastry..." said Pinkie in a low, seductive tone. Rainbow Dash felt a new buzz of arousal, which she now loved as much as her belly. She simply nodded her head, her overweight body staying completely trapped in the chair.

Lifting the first pastry off the tray, Pinkie Pie carried the cheese-inflated square over to Dash’s willing mouth. Leaning over in the same way as last night, Pinkie’s stomach oozed over Rainbow Dash. However, this time Dash’s belly also melted out like butter – finally not just Pinkie Pie's. Rainbow smiled at her, as she watched her preciously place the pastry into her mouth. She took one bite, and the melted cheese oozed over her tongue. "Ohh yeah, that's good," moaned Dash, the gooey cheese almost jamming her mouth together. Pinkie Pie could do nothing more but stare deeply, lustfully, into her partner’s pleased eyes.

Pinkie took the second bite, unleashing more luxurious cheese. A large blob fell out of the overstuffed pastry, splattering onto Dash’s wobbling belly. "Oops, dropped some,” Pinkie squeaked. "Looks like I might just have to lick it up..."

Pinkie bent down, resting her head onto Dash’s soft, cushion-like stomach. With one, slow movement, she licked up the creamy liquid cheese and gazed at the chubby blue Pegasus above her. Rainbow Dash quivered with arousal, staring deeply into Pinkie’s eyes. She dreamed of staying captive under Pinkie until she could barely walk; until the last feather on her wings was sucked up into her fat. She realised she would undoubtedly have to live with Pinkie from now on; she could no longer fly up to her current Cloudsdale home. However, this did the opposite of worrying her. She felt a new belonging in Sugarcube Corner. There was more energy in its atmosphere, than calorific energy in its cakes!

So, as Dash and Pinkie swallowed the last of their morning feast, Dash began to wonder – how would their friends react? Would they be disgusted? Would they get angry? Or, would they admire it, and join in the luxurious stuffing... Rainbow hoped for the latter. Applejack would surely do well at it, with all the apple pastries they take pleasure in baking. Maybe Twilight would enjoy it too; being able to lounge for hours studying, her slump of fat keeping her legs from being able to move. There was that one time - when she first arrived at Ponyville. She had completely stuffed herself with Applejack’s pastries - and who knows, maybe she enjoyed it!

But ignoring whatever their friends thought, Dash and Pinkie were piling on the pounds together, and no one could stop them...

It seems Rainbow Dash finally showed her true colours. She never knew her rainbow mane was lacking the bright touch of Pink... But now she finally had it, forever by her side...
