Ever since Fluttershy can remember, people have always told her that she was ‘different’ than most pony girls her age. Sure, her long flowing pale rose colored hair and matching tail fur, cute flittering pale gold colored wings, dazzling moderate cyan eyes, large bountiful curves, and statuesque stature were nothing to really be ashamed of, but she just didn’t like the attention she got from having such a body. Even as a filly girl, she stood at least half a head taller than most of her female peers and level with most of the boys. The staring and teasing only got worse once puberty hit, wing molting was the least of her problems; her ample perky grapefruit sized orbs that adorned her chest earned quite a few nicknames, stares and murmurs until she was finally out of school.
Out of all her Cloudsdale Academy classmates that stood by her and stood up to her bullies, there was nobody she cherished more than Rainbow Dash; a very tomboyish pegasus girl with cerulean wings, cerise colored eyes, and a spiky mane of rainbow colors to fit her name. They’ve been very close friends ever since the day the moderately flat curved and shorter pegasus girl defended her honor with a mighty Sonic Rainboom and eventually led to both of them acquiring their cutie marks permanently adorned to their hips. This was one of the reasons her good friend decided to execute a plan that she liked to call: “Operation Flutter Bloom!!”
After a pretty minor incident at Sugarcube Corner involving the ever energetic Pinkie Pie holding two actual grapefruits against the bashful Fluttershy’s bosom to compare the nearly identical size and shape, the unease Dash could tell she was trying to hide finally convinced the tomboy pony to find a way to boost her confidence in her own body… with maybe one or two more perverted thoughts of what that would entail pushing her a little further to go through with it. She first began by renting a book from her studious friend Twilight Sparkle’s library on potion making, then taking flight to the Everfree Forest to visit her zebra friend Zecora for supplies. Both strongly advised her to be careful as she took mortar and pestle to her work, brewing the contents to a smooth creamy white ointment that could be mistaken as lotion… even though the results said it should have come out as a *potion*… Dash merely scoffed this off as an error in the text; the directions were completely in rhyme anyway.
The final step was sneaking into Fluttershy’s cottage as the timid animal lover took her evening shower; the only real obstacle was dealt with by bribing her pet bunny Angel with a bushel of carrots to keep quiet. In no time, she had emptied the contents of Shy’s regular moisturizer into a flip-lid waste basket and poured in her newly concocted confidence boosting lotion and finally made her speedy escape through the window with a giddy grin, barely able to sleep from the giddy anticipation of seeing the results of her hijinks tomorrow.
The next morning, Dash made her way eagerly to the park, knowing Fluttershy would be there feeding the ducks and doves, but she was definitely not prepared for what she saw. Walking towards her with her arms desperately trying to cover her chest and her hands fidgeting at her waist walked a definitely different looking pegasus than the one Dash had met at the sweets shop the other day. For one thing, she looked as though her pale yellow turtleneck sweater was smuggling not a pair of grapefruits, but some slightly large ball shapes with at least an inch or more jutting outward; also clear was that she had no bra on, evident by the jiggle that rang through her torso with each step or sudden movement and the two clear points of her nipples poking out like two little coin sized lumps. Another realization hit Dash when the timid girl finally stepped closer to her; already a half a head taller when she last saw her, now she was definitely a full head taller with Fluttershy able to rest her shin atop Dash’s head without leaning and Dash easily able to stare directly at her chest without looking down… something she tried not to do desperately.
“U-uh… h-hi there… F-fluttershy? Did… did you do something with your hair today?” Dash said nervously, staring up to make eye contact.
“No…” she whispered bashfully “I… I just…I must have had a little… growth spurt last night. Is it that noticeable? Because my clothes may have just shrunk in the wash or something…” one of her feet scraped at the ground a bit, a common habit thanks to her human-equine nature.
“Um, ah… a little. Just a little though!” Dash stammered. “But you look really awesomely cool like that!”
“Really?” her voice raised a bit, though her shyness continued. For some odd reason, she felt an odd tingle all last night after her shower and it only went away when she fell asleep, only to find that none of her clothes fit her quite right; she had to go without a bra today and her panties were constantly giving her a wedgie, thanks to her swollen firm cheeks pressing roughly against the white satin fabric. She began to rub her thighs together the more she stood next to Dash, suddenly feeling the tingling intensify every single moment and it felt really good, like being tickled by a swarm of butterflies.
“Fluttershy are you… you’re… getting… b-b-b… big…” Dash stammered, gazing in awe as in short pleasureful spurts that forced an adorable squeaky moan from Shy’s pouty lips, her body began to inch higher and higher above the winged rainbow tomboy. Dashie suddenly felt herself being uppercut in the face by twin pom-poms of marshmallow… at least that’s how it felt as Shy’s already head sized breasts began to balloon outward and rise with her stretching height, already sporting bulging areola and nipples under her tightening sweater fabric in large bulging bumps.
Her hips made a slight painless creaking noise as they began to widen straining her light green skirt to its limits and causing it to make its own creaking noises as it almost painfully hugger her bloating curvaceous upper thighs. Her growing size meaning the skintight band of buckling cloth was only able to hide all of her Venus mound and the very top of her swelling firm, holiday ham-like buns up above and a very tiny fraction of her not-so tiny bulging yet powerful curvy thighs from below; which were now roughly as thick as her still narrow waist each.
The growing pegasus girl winced in a crude mixture of embarrassment and soothing tickling pleasure as she quickly reached her longer yet still dainty hands down to cover the very obvious Venus bulge and growing wet spot on her all-curve-exposing skirt that hung as low as a pornstar showing off a thong, which her panties did a fine job of emulating until they finally snapped and fell to the ground… almost completely moist with her fertile love honey. This would only serve to jut out her ridiculously huge mountains of mammary even more once she finally squirmed her upper arms behind them, enticing another graceful squeak-moan. Her monstrous hooters were now as huge as the smaller Rainbow Dash’s torso and at least massive enough to fit two of her already enlarged heads into each soft squishy pillow that was starting to destroy her sweater; their cusps distending to just above her belly button on her lean smooth tummy. The pale yellow fabric finally began to give way once her growth began to slow down, a few tearing sounds signaling one or two gaping holes finally fissuring between the fabric and spilling bulging oval shaped sample of her boobflesh that weren’t already exposed by the bottom of her poor sweater only covering a few trace inches below her areola, exposing a billowing flood of undercleavage while her nipples bulged up top like she was smuggling two throbbing plums under the injured top.
“Um… Fluttershy?” Dash stared up in a dazed state, only now taking in the fact that she was now only as tall as one of the amazon goddess-like pegasus girl’s sleek curvalisciously sexy legs was long; coming up just directly below her moist pussy underneath the tissue-thin skirt clinging to her for dear life like it was made of green solid cellophane.
“Dashie…” Shy cooed with a motherly soft, yet sultry purr before quickly scooping up the filly-sized girl and bringing her into a very tight hug with her face squashed between her two mountains of boobflesh. “naughty-naughty Dashie-Washie, you used some kind of puffy-wuffy potion to make me all biggy-wiggy, didn’t you~?” she playfully turned her torso slightly left and right, letting her restrained tits toss and turn in what little room they had and letting her captive feel every jiggle and undulation.
“What!? You…” she muffled through a near inescapable prison of warm great dane-sized sweater-puppies.
“Twilight let me know of your little plan, it was such a sweet incentive that I just played along. But I never thought it would make my body even bigger and yet… I do feel so much better this huge~! Mmm… imagine all the bigger animals I can snuggle now… or should I just focus on you~?”
Dash only rabbled incoherently when her head comically popped out of the ‘surface’ of splitting wool and flesh, her wings felt like they would never stop being spread out from arousal and quite frankly, neither did Fluttershy’s.
The amazon pegasus looked around at the gawking pony people in the park, witnessing the entire event and many still staring. It somehow felt… perfectly fine to her, in fact as crazy as it sounded, she was enjoying all this attention; so what if some were jealous, scared, confused, so what? The only opinion of her titan pillowy curvaceous body that mattered to her now was her own… and the one that made this all possible.
“What do you say we go back to my place? I still have the rest of that lotion to go through, I wonder if you’re as good of a masseuse as you are an ace flyer?” she giggled warmly, almost glowing with joy and a bit of mischief.
“Wh-what!? I… uh… buh… bluh…” Dash felt herself foaming at the mouth before passing out leaning against her wall of puffies.
“I’ll take that as a ‘maybe’.” She cradled her very close friend’s sleeping body in her arms and shelf of her bust, taking off in a joyous skipping stride towards her cottage, so that her lovely huge pillows on her chest and backside happily jiggled and wobbled the entire way home.
