Twilight Discovers Rainbow's Interesting Kink

“Oh wow, you’re right Rainbow, these are super soft!!” Twilight Sparkle exclaimed excitedly, prancing in a small circle on what seemed to be the softest cloud in Equestria.

Rainbow Dash giggled, watching as Twilight pranced in a circle, hovering a few inches above her head. “Now you see why I love sleeping on them so much!”

“It is just so incredibly interesting how DENSE they can be to pegasi! I mean I know we all walked on them before, but really studying it is super impressive! I mean, I really should get my quil and notepad! This has so much potential for deeper study! How can something so wispy and light be so soft and thick!?” Twilight giggled and bounced on the cloud below her.

“Oh Twilight, it's cute how you geek out over the simplest things,” Rainbow said shaking her head with a smile. She dropped gently out of the sky and landed on the cloud next to Twilight.

Twilight felt her cheeks grow warm with some embarrassment at her mini geek-out sesh. She sat down beside Rainbow, stretching her wings and smiling widely at her.The only thing Twilight’s mind was screaming was She called me cute!!! She thinks I’m cute!

Twilight had a bit of a crush on her Rainbow pegasus friend, and she had a small hope that the pony would return her feelings. But the purple alicorn never bothered to ask, out of fear of what she might say. But now…! She must have SOME feelings about me!

After a moment of looking into each other's eyes, Twilight cleared her throat and cocked her head at Rainbow.

“Ya know… Rainbow… uh, ever since I became an alicorn I’ve really… appreciated the time we’re spending together! I love getting to learn all about being a pegasus,” Twilight said, scuffing the cloud beneath her with her hoof.

Rainbow looked thoughtful for a moment, then stepped over to the far side of the cloud they were on top of. “Ya know Twilight, I really have too! And I wanna show you something else,” The pegasus reached a hoof into the cloud and dug out a beachball sized jumble of cloud. “They actually taste really good!”

“Taste??” Twilight cocked her head, “But they are only-mmph!” She was interrupted by Rainbow Dash gently shoving half of the cloud she held into her maw. Twilight gulped it down, and discovered she was right! While it was mainly just condensation, it was somehow all fluff too! It was like eating cotton candy mixed with a marshmallow. There wasn’t much flavor, but it was refreshing.

“It’s like cotton candy!” She exclaimed, “Except it doesn’t melt, and it's so dense, yet so light!”

Rainbow nodded, but before Twilight could say anything else, the rest of the cloud was shoved into her maw. Twilight’s cheeks puffed outward into a large chipmunk like shape as the cloud filled her mouth. She somewhat reluctantly gulped it down, feeling her belly grow full with all of the condensed cloud inside.

“Oof, I’m full Rainbow. Those clouds are good but very filling,” Twilight said, standing up again from her sitting position.

“Aw, nonsense Twi, have a little more!” Rainbow said, “Once they get in there they tend to condense, so something like this,” She pulled out another beach ball sized bit of cloud, “Turns into this!”

Before Twilight had the chance to open her wings and take off, her maw was absolutely stuffed with soft puffy cloud bits. “MMMPHH!!!” Twilight protested through the cloud, but couldn’t make much noise other than the muffled gurgle as she was forced to gulp down mouthfuls of cloud.

Oh dear… this is getting rather strange… Rainbow seems to be enjoying this a little too much. I wonder what she thinks she’s up to!

Twilight managed to gulp down the last bit of cloud, feeling every inch of empty room in her stomach fill with puffy condensed cloud, and she could feel her belly begin to expand slightly as it was pushed outward by the sheer volume of its contents.

“See, you managed to fit all of that in there! Isn’t it so cool having wings, you get to chow down on clouds all you like!” Rainbow Dash exclaimed, digging up another pile of pillowy cloud.

“Yes, it is…” Despite how confused and nervous she started to feel at the strange actions of her friend, the sheer force of curiosity and soft spot for the cyan pony kept her standing in place, “So… this doesn’t work on non-pegasi?” She asked, watching intently as the pile of cloud behind Rainbow grew larger.

“I mean, I know they wouldn’t be able to pick it up, but hmm, I’m not sure actually…” She said, pausing momentarily, “Perhaps we should try it out sometime?”

Twilight cocked her head, unsure what she meant. “You mean, ask an earth pony or unicorn to try some cloud?”

Rainbow nodded thoughtfully. “That gives me a good idea Twi,” She said, scooping up some of her cloud-mound, “but for now, open up wide!”

“Open wide? I said-GGGUUULLLKKKKKK!” Twilight stumbled backward as Rainbow stuffed a huge mound of cloud into her maw. She practically shoved it down the alicorn’s throat, and Twilight was forced to continue gulping down hoof-ful after hoof-ful.
As she was stuffed silly with the wonderful pillowy substance, the princess’s belly was forced to accommodate all of the influx of cloud. Slowly but steadily, Twilight’s belly inched outward a few centimeters. At first it wasn’t noticeable, but soon her once trim middle began to press outwards. A gentle curve began to form, causing an audible response from within. GGUUrrggLLLLlEeee… came the sound of Twilight’s stomach. It rumbled in protest as she was forced to fill it past capacity.

Still, Rainbow pushed on, filling the poor pony up more and more. Twilight barely had any chance to breathe other than quick gasps between hoof-fuls, or desperate pantig through her nose.

Oof.. so… full! Twilight thought, still attempting some muffled protests against the stuffing. But try as she might, the complaints were all in vain.

Soon enough, Twilight’s belly had swollen enough to be considered moderately bloated. Her poor tummy had gained a nice spherical shape to it. She not only swelled downward, but outward as well. Her barrel was visible from just about every angle now, and she whimpered as it rumbled and gurgled more and more the bigger it got.

Finally she was granted a break as Rainbow stuffed the last bit of cloud in that she had collected, and Twilight tumbled backward in an awkward heap. She sprawled her wings out over the cloud as she lay on her back, and panted in exhaustion.

“Well now, looks like all that cloud really did a number on your tummy so far, Twi!” Rainbow Dash giggled. At first she thought that Rainbow was making fun of her, but when she lifted her head to look down her body at the pegasus, she realized there was a slight blush to her cheeks. The smile she wore was loving rather than amused, and her eyes were fixated on the curve of Twilight's swollen tummy.

“I… you-” Twilight didn’t know what to say. She was absolutely confused, embarrassed, and slightly angry, but all of those emotions were no match for how much power Rainbow Dash’s lok held. Twilight found herself blushing as well.

She was quickly brought back to reality as she jumped at the sensation of Rainbow resting a hoof on her bloated belly, and she squirmed in embarrassment.

“Let’s see how much bigger it can get…” Rainbow Dash said, and quickly stuffed another mouthful of cloud into Twilight’s maw.

The forced stuffing resumed, but this time Twilight was laying back enough to watch her belly slowly swell outward. Not to mention getting to watch Rainbow Dash work right over her. The pegasus was focused, and made sure to give Twilight just enough eye contact to keep her curious, embarrassed, and most importantly, absolutely love struck.

The rumbles from her tummy signaling its overwhelming fullness were just present enough to keep her mind partially on her swelling though, and she squirmed in fear as she watched her tummy go from slightly bloated, to very bloated, to that of a pregnant mare, and past that to the size of a beach ball. She didn’t even know it was possible for her belly to stretch this far! Yet despite how stretched her skin must be, it continued to stay relatively squishy and soft. Rainbow Dash certainly made that fact known.

Every time Dash’s body bumped or pressed into Twilight’s swelling midsection, which happened more frequently as she swelled further, it managed to give in enough for Rainbow to sink in an inch or two. And as she grew, it continued to maintain the same level of give. Twilight was absolutely astonished by the entire scene, maybe it was worth a bit of scientific research…

“Ohh, your poor tummy…” Rainbow continued to comment in small nurturing yet teasing statements, and Twilight wasn’t quite sure how to feel about it. She was utterly embarrassed by how she looked, but she couldn’t help but shake the feeling that she enjoyed a bit of tummy rubbing behind all that fear and confusion. But did she enjoy it to the extent of being force fed ridiculous amounts of cloud? She wasn’t too sure.

She was starting to question how much Rainbow Dash enjoyed the scene as well. The pegasus seemed so incredibly fond of her tummy, which was now closing in on the size of a yoga ball. Rainbow was forced to lie on top of it to reach her mouth now, and she was not afraid to give it some love and attention in the process. But something about the way she rubbed it, and stuffed Twilight with so much passion, made her suspicious of her motives here. Rainbow is REALLY enjoying this… but just how into this are we talking? I’m so… so… so full, I’ve ever been this full in my life! But Rainbow seems rather… familiar with this type of extreme stuffing. But I wonder how big she intends for me to get… Twilight let out a rather awkward moan of exhaustion and strain through a particularly large mouthful of cloud. She had spent so much time wiggling and squirming and struggling that she had tired herself out, yet she was still forced to gulp down the squishy substance.

She noticed Rainbow Dash blush at the sound of her moan, and realized exactly what was going on immediately.

Rainbow isn’t just enjoying this, she’s INTO IT! Is she getting turned on by this? Twilight wondered, and she exhaustedly squirmed again. The pegasus continued rubbing and prodding and poking her tummy as she went, and the faces she made mostly confirmed her hypothesis.

Finally, as her belly surpassed the size of an over-inflated yoga ball, Twilight was given a break. Which she soon realized was due to the fact that the cloud they were on top of was growing rather small. Twilight let out a small burp, and her belly rumbled and gurgled once more as if concerned for its own fate.

“Oooh, look at you! So… so full!” Rainbow cooed, rubbing her stomach.

“Oooooooohh, I’m so stuffed Rainbow Dash! What in the world was that!!!???” Twilight whimpered, and attempted to get to her hooves. Which she soon discovered was an embarrassingly big challenge in itself.

Seeing her struggle like an upturned turtle, Rainbow eventually reached a hoof down to help her. She rolled Twilight onto her belly, which was apparently swollen enough to brush the cloudy floor beneath her. Twilight felt her cheeks grow a deep red at the realization of just how large she was.

“Look at that! Your belly wasn’t the only victim Twi!” Rainbowdash observed, prodding her ass.

“EEP!” Twilight jumped in surprise, looking back at her own flank. She indeed found a somewhat swollen butt, and felt some pressure as she turned her head. Her neck and legs had gained just a little bit of swelling, not a lot, but just enough to be noticeable, and make it harder to turn her head or bend her legs. But the main victims still seemed to be her belly and behind.

“Did I… gain weight from clouds? Clouds don’t have calories!” Twilight whimpered, realizing she had become probably two times wider than she was before.

“I’ve heard of this. In a sense, yes, but also not quite. I think it's what the condensation in the clouds does to your figure. Since you got so much cloud inside your belly, your body distributed the water in other places! It's like being filled with water but within your skin and body!” Rainbow giggled, giving her butt a gentle slap.

“What in Equestria? How is that possible!!??” Twilight yelped, watching her butt slosh and jiggle.

“Come on, I wanna see what happens when we can get more in there!!” Rainbow said, avoiding the question. But when Twilight realized she was about to stuff her again, she opened her wings to fly away. But Rainbow Dash didn’t have the reputation of one of the fastest ponies around for nothing. Before Twilight had a chance to say anything, do anything,or escape in any way, she was grabbed by her forelegs and lifted into the air.

Twilight began to panic, and flapped her wings in another frantic attempt to get away. But whether it was due to all of the “water weight” or her wings still being challenging to control, she didn’t seem to make much progress.

Her stuffed tummy sloshed and gurged as she swayed and bobbed around in Rainbow’s grip. Her wings slapped her own belly as they attempted to flap, and she discovered that it had swollen just enough to be too heavy and in the way to fly. Apparently Rainbow Dash was more clever and put more thought into this than she realized.

Rainbow tossed her into a large cloud cluster, and Twilight yelped in fear and she fell downward and downward until… PLUNK! She landed in between a few different clouds. Her belly and hind legs reached downward and through the cloud, while her forelegs were stuck resting utop the surface of it. She struggled and squirmed, but try as she might, she was stuck, buried in a cloud. Which seemed to work out absolutely swimmingly for a particular pegasus.

Soon enough, Twilight’s maw was stuffed to the brim with cloud bits, and she found herself gulping down mouthful after mouthful again.

She moaned and whimpered, too exhausted to fight too much or try and squirm out of the clouds she was lodged in. She was left to feel like a helpless blimp as she swelled and swelled beyond any logical size. Her belly billowed out more and more, and she felt a rush of cold breeze as it popped out on the underside of the cloud surface she was stuck in. Her dome of a tummy became more of a vat of cloud storage as Rainbow crammed and condensed as much cloud as she could inside her.

Now Twilight felt an odd sensation as her ass and the rest of her body began to thicken up. It was like a combination of fat and perfect roundness. Some places blooped out into small rolls, but at the same time she maintained a rounded, swollen shape. Her cutie marks became stretched and almost comical as they were forced to swell along with her belly. Her cheeks, despite being puffed out with an almost constant full mouthful of cloud, had gained a rather swollen permanent appearance, and her neck had began to thicken ever so slightly.

So… full… so… stuffed… Twilight’s thoughts became scattered as she swelled, only able to struggle and moan and whimper every once in a while. But her belly was no less audible. It gurgled and rumbled and groaned as Princess Twilight Sparkle was stuffed silly with condensed clouds. She could hardly believe what was becoming of her, and how she had managed to let herself become stuck in a cloud like this. She was so perfectly restrained just for Rainbow’s delight.

It was almost a half an hour later when Rainbow Dash finally hunched over in exhaustion and decided Twilight had swollen large enough. The princess was left panting in defeat, blushing harshly and whimpering.

Rainbow Dash landed on Twilight’s back, which had become a much larger surface than it had been before due to how much Twilight’s belly had swollen outwards into a large dome.

Twilight was about to weakly snap at her something along the lines of WHAT THE HAY WAS THAT YOU CRAZY PONY, but stopped herself as Rainbow began rubbing her belly and comically swollen butt.

Twilight had become a blimp. Her belly was probably too big to even fit in the Golden Oak Library’s biggest room, and her ass had swollen to about ⅓ the size of her tummy. Each of her limbs had become noticeably thick and puffy, and she restered her forelegs on the front of her swollen chest and belly. Her neck had thickened up as well,and was complemented by two adorable swollen cheeks. The only thing remaining completely untouched was her wings, which were sprawled out over her dome of a belly. She wouldn’t be using those in this state. The cloud she was once trapped inside of had become rather small, and while she still remained lodged within a huge area of clouds, her tummy had billowed out below the level of the lowest cloud, and she probably looked like a strange purple orb escaping the clouds from below.

Twilight was absolutely massive, exhausted, overly full, and probably immoble, unless she decided to roll somewhere. But she couldn’t ignore the fact that there was an obvious heat and wet sensation coming from between her legs.

Rainbow took notice too, and started to giggle. “So Twi, how do you like this?” She asked, prodding the surface of her stomach.

Twilight let out a quiet moan in reply

“For all that struggling and squirming, you seem to like being absolutely stuffed silly,” Rainbow cooed, rubbing her poor tummy, “so full, so swollen, and you can’t do anything about it.”

Twilight blushed even harder at Rainbow’s teasing. Maybe… I do like this a bit…

Before she could say anything in reply, she noticed Rainbow inching closer to her more private area. She whimpered in anticipation, and squirmed just enough for Rainbow to feel her jiggle and wobble beneath her.

Maybe after we have some alone time I’ll decide whether I really like this or not… it can’t be that bad…
