Rainbow Dash grinned to herself as she sat on a comfortable cushion within Fluttershy’s cabin, the butter yellow pegasus mare was sitting nearby, looking at her friend meekly. They had been sitting in near silence for a good few minutes after the blue pegasus had arrived to chat with Fluttershy, following some concerns that the, well, shy mare was an easy target to be picked on, and after the disaster with Iron Will, Rainbow wanted to help her in a less stressing way, and also a rather unorthodox one at that.

“Um…a-are you sure about this, Rainbow Dash?” Fluttershy asked timidly, looking down at the ground but still towards her friend.

“Totally, ‘Shy, this is what you need!” Dash replied, patting her with a hoof.

Fluttershy just nodded and remained quiet as Dash trotted to the window and peeked out, flapping her wings impatiently. They said they’d be here any minute, and she was eager to start Fluttershy’s training. There was a knock at the door and Dash excitedly answered it, it was Derpy the mailmare and behind her was many other mail ponies carrying down boxes and boxes of food, from apple pies to muffins to full cakes. Rainbow Dash knew they were for Fluttershy, but couldn’t help but drool a little at the sight herself, her trim cyan stomach giving a slight rumble that she ignored, for now anyway.

“Oh wow, um, Dash? Isn’t that a …lot of food?” Fluttershy questioned, confused as to why her friend had ordered all this to her house.

“Yep, and there’s a reason for it ‘Shy…you.” The pegasus grinned.

“U-uh…m-me!?” Fluttershy was now even more confused, and a little scared.

Rainbow Dash walked over to the butter colored mare and smiled gently at her, reassuringly. “You’re always getting picked on, and after that uh…incident with Iron Will I thought of a new way to make big and strong…by making you *big*!” she chuckled.

Fluttershy gulped, she wasn’t totally sure if this idea of Dashie’s was a good one, but all that food…her tummy did let out a little growl at the look of it. Sucking up her fears, she slowly nodded, signaling that she was willing, if still a little reluctant to get into it. Dash smiled and patted her head, before having the pegasi team cart all the goodies into the cottage, minding Fluttershy’s myriad pets of course. The various packages took up a good chunk of the building, even when distributed around to fit, and both pegasi mares almost sweatdropped at this little fact.

“I know ya probably a bit, well, *very* reluctant to do this, so I decided that I’d join you, ‘Shy.” Rainbow Dash said, winking at her friend.”

“R-really? B-but don’t you want to stay…well, um, in shape Dash?” The pink maned mare was stunned.

“Pssh nah, if it makes you feel better about this I’ll gladly blob up with ya!” the cyan pegasus immediately took a big bite out of a nearby cupcake to drive her point home.

Confidence boosted, Fluttershy wanted to take a bite, but then Rainbow stopped her, producing two odd looking fruits from somewhere and putting them onto the table before them. When questioned, Dash explained that these were odd little fruits specially cultivated by Zecora, which when ingested, caused an immediate, 100 fold boost in a pony’s appetite and stomach capacity, as well as speeding up digestion for a few hours…a great trick for weight gain.

“Well uh…down the, hatch?” Fluttershy giggled nervously, as she and Rainbow counted to three and gulped down the fruits at once.

The results were instant; both mares were immediately clutching hooves to their stomachs, which let out loud, roaring rumbles that caused their bellies to visibly quiver even without any fat. Starving suddenly, the two eyed up the mounds of treats before them and drooled a little, hunger overtaking them. Fluttershy was first to practically dive in and begin stuffing her face, not even pausing to savor the taste as she only cared about filling the black hole that had formed in her belly. Dash followed suit, jumping into the pile of pastries and cakes and shoveled them down, both mares giggling in their gluttony as their flat stomachs began to gurgle a little and slowly bulge out as they filled. Neither noticed their growing roundness and the two continued to gorge, Fluttershy lying on her back as she held a pie between her hooves and stuck her face into it, loud slurping, chomping noises coming from the dish as her gut ballooned even bigger.

Rainbow Dash grew a little slower than Fluttershy but was no less hungry; the blue mare crammed whole cupcakes into her mouth in multiples before gulping them all down, her belly beginning to push her legs apart as it domed out downwards more. She was alerted from her hungry stupor by Fluttershy letting out a groan, the butter pegasus’ belly was touching the floor and making it harder for her to move towards more food, gut gurgling away as it tried to process the meal. Dash instinctively began feeding her friend by hoof; her own growling guts would have to wait until after the main feedee here had eaten her fill, and by the time she had eaten enough to be full, Fluttershy was near spherical and had to be rolled to the last pile she’d claimed as her own, her stuffed innards sloshing and groaning as she moved, Dash’s own tummy now dragging along the floor as she pushed Fluttershy about with much grunting.

“Urrf…thanks…Dashie…*hic*…” the now literal butterball gurgled, wiggling her useless legs in thanks and flapping her wings.

“No problem ‘Shy, now then…come to Dashie you delicious morsels!” the cyan tomboy squealed as she waddled towards the remaining piles of snacks as fast as her floor hugging belly would allow.

Fluttershy watched as Rainbow Dash rapidly ate through everything, it was like she’d been waiting for an excuse to pig out for her entire life, with the gusto she was putting into this. She only stopped to gasp for breath or let out a room making belch before returning to mindless gluttony. As she ate and ate and ate her belly began to push her off the ground too, but thankfully not before she also reached her maximum capacity, and with some considerable effort she half waddled half rolled herself besides Fluttershy, licking a tiny fleck of pie from her cheek that she’d missed, making the yellow female giggle. Both were too tired and full to talk so they merely shared contented smiles as they yawn-belched and drifted off to sleep for a long, digestive nap.

When Fluttershy awoke hours later, she felt…warm. Very warm. And very, very soft. Her whole body felt like it had been smothered in warm dough or something, and she was finding her attempts to move were very slow and sluggish. Her eyes opened slowly and she let out an adorable yawn and smacked her lips. And when her eyes opened, she let out a loud squeak of shock: She couldn’t see the floor at all, only a large expanse of butter colored blubber, and her cheeks were huge sagging footballs, with her chin having become adorned with an extra three or four chubby chins below it that jiggled when she turned her head. Her plot was taking up all the ground behind her, with equally as expansive flanks, cutie marks enlarged and stretched out to fit on the widened fatty flesh. Her belly squished out below her and seemed to press itself out from her sides and front, spilling onto the cottage floor like a yellow beanbag, and her limbs were padded out with rolls of excess fat as well. She was a blubbery butterball now more than ever.

She was too shocked to say anything, and she looked up to see the equally as blobby form of Rainbow Dash before her…or more accurately, the pegasi’s enormous blue plot bouncing and wobbling as she hummed to herself, making breakfast from Fluttershy’s own fridge. She’d be annoyed if she wasn’t so preoccupied already. The bubbly blue mare finally turned around with a plate of grilled greens in her mouth, allowing Fluttershy to see how big she was properly: Dash was smaller than her for sure, but seemed to pile most of her weight into her belly, unlike Fluttershy’s plot centric blubber. Her cheeks were large and squishy, and she had at least 4 chins sagging below her head, and her previously mentioned belly was so large her hooves, nestled under large ‘sleeves’ of rolly leg blubber, barely touched the ground.

Her flanks and plot were still huge of course, spilling out behind her like a bouncy castle, but not as large as the yellow mare’s own butt.

“Oh hey ‘Shy, how are ya?” she asked after setting the plate down on the table and parking her big rump on a comfy cushion, voice sounding deeper and slower due to the extra weight.

“F-fine…um, Dash? We’ve…*really* grown…!” Fluttershy muttered, taking in her size still, her own voice more bass and sluggish as well.

“Heh, side effect of the plant, ‘Shy…look at you! You’re all huge and bulky now, like one of those sumo ponies from Neighsia!” the blue blob grinned happily, “Nopony’ll dare mess with ya around town now, and you know how intimidating those guys are!”

Fluttershy sighed, Dash did have a point about that, those ponies were well known for being very big and intimidating. Slowly, she began to smile a bit, the fatness of her body did actually feel quite nice, the warmth was gentle, and the sensation of her blubber jiggling with each movement made her stifle a giggle. Dash also giggled and gave her friend a rather squishy hug.

“Now then, lets go show the rest of Ponyville the new and improved Fluttershy!” the rainbow maned girl cried, Fluttershy donning a confident, narrow eyed smirk and nodding in agreement.

The streets of Ponyville shook slightly as the enormous mares waddled down them, ponies staring with jaws agape as a blue and yellow wall of blubber jiggled towards the many snack selling stalls and shops. As the two tubby titans slowly jiggled along, Rainbow Dash cheekily slammed her plot into Fluttershy’s, causing intense ripples along her side. The butter mare giggled and returned the favor, rump bumping her friend back. Nobody would mess with Buttershy now, not at that size, and definitely not with Rainbow Dash at her side!
