Expansion Erotics and Magical Maladies

Rainbow awoke, a pounding headache causing her to clutch her head before the events that transpired came rushing back to her. Springing to her hooves, she glanced around her new surroundings. It looked like the middle of some grassy plain, almost featureless apart from some boulders embedded into the ground a couple of feet in front of her. Continuing to search, she found nothing. No pony, or dragon, was anywhere nearby. “Fluttershy! Twilight! Applejack! Anypony, hello!” she called out. The only noise that returned to her was that of rusting grass, the long stalks swaying in a mild wind.

“Damn it Twilight, why did you have to cast that stupid spell of yours?” She grumbled, kicking a loose pebble a short distance ahead of herself. Taking a small breath, she looked around once more, her eyes flicking skywards. Above her, were many clouds. Flitting between them, was a couple of small shapes, which looked equine in shape, though due to the distance, it was hard to tell. “Ah yes! Civilisation! I’ll just go up there and ask where the hay I am, then I’ll find my friends!”

Nodding to herself, she crouched down, ready to launch herself into the great blue expanse. Simultaneously, she jumped, whilst pumping her wings to achieve maximum launch velocity. It was a move she had practiced for years upon years, virtually muscle memory at this point. Reaching up, she flapped as hard as possible, ready to be carried off into the air. This was suddenly cut short, as the prismatic Pegasus landed square on her stomach, knocking the wind out of herself.

Jolting up, clutching her lungs, she could barely shout out several cusses, in between wheezes as she attempted to get her breath back. The instant Rainbow did, she pumped her wings as hard as possible, the air becoming turbulent from the downdraft. And yet, the harder and harder she tried, the less she felt she was moving. Hovering a scant meter or so over the ground, she gave up, landing on her hooves this time. She panted and breathed, sweat trickling across her body. “What the hay is going on? Why can’t I fly!” She glanced up again, those Pegasi above having no such issues flying. Although, it seems that her shouting and mad flapping had drawn their attention, as several of their number approached her.

“Great, just great. Not only did I suck, but the locals saw it too. What are they going to think when they see a Wonderbolt sucking even more than a foal at flying?” Sulking, she waited for those Pegasi to come down. As they drew closer, she noticed something, off, about them. They all seemed to be the same dull shade of white, every part of them. From their manes to their hooves. Secondly, their ‘wings’ lazily flapped, wings which seemed to be a solid mass, rather than made rows of feathers. Before she could question anything else, they landed next to her. Her voice caught in her throat, as she stared wide eyed at the not-Pegasi. Blank faces, partially transparent bodies, a slight glow around their edges. The creatures surrounded her. “What do you want, you creeps?” She shouted, preparing to possibly tussle with these things.

They said nothing, before one of their number brought out an object. A metal cylinder, around a meter tall, with a rubber hose attached to the nozzle, where a comically large valve was located. As one, they moved, quick as lighting they seized Rainbow, one holding each leg. “Gughhh!! Let me go!” To her credit, she did try to flight back, her strong limbs attempting to lash out to kick and punch the monstrous apparitions. And yet, nothing. She could have sworn she bucked on right in the head, only for it to continue gripping her leg. The last creature took the tube, shoving it between Rainbow’s lips. Before she could spit it out, a white glowing band was fastened around the back of her head, locking it in place.

As soon as this was done, the valve was turned, hissing gas flowing down the pipe and into the Pegasus. “Mmmph, mmmpph mmmmmph!!” She shouted the best she could, as the rush of gas built up. Already, she could feel her normally concave belly begin to swell outwards. Almost as if she was a party balloon. Larger and larger her stomach grew, rounding outwards, the swelling extending further up her front, to the point her entire torso was beginning to round out. Larger and larger, she felt the gas start to find other places to fill.

Her butt was the next victim. Each cheek starting to rapidly puff up like airbags, her cutie marks expanding to cover the much greater canvas size that they were getting forced onto. Already, her body looked severely swollen. Her belly resembled a beach ball, her bottom following suit. Again, her body looked for more places to fill with the abundance of gas. Her forelegs and thighs were the next targets, quickly dwarfing her hooves, which were beginning to suck into the greater mass of her inflating limbs. Her face cheeks puffed up, as excess gas that wasn’t forced down her throat found it’s way there, tennis ball sized lumps developing.

From there, it got progressively worse for the speedster turned dirigible. The endless tank had put her body under such stress that her legs could no longer bend, pressure forcing them to remain spread eagle. Her chest and belly, the largest parts of her, were rivalling carts for sheer magnitude. Almost like a rubber ring, her chest expansion ringed around her back, forming a cyan coloured tire, a tire which was beginning to swell around her head, trapping the back of her mane. Similarly, her tail was nought but a piece of decoration atop the boulder sized globes that her flanks had blimped up to. Her cutie mark was over double her old height, every second continuing to expand it further towards billboard size.

Her eyes were squeezed shut, overwhelmed by the feeling of her body reaching such excessive sizes. Every moment her limbs turned more and more into pool toy-esque shapes, wider and wider, but still being firmly gripped by the creatures. The only other part of her that remained normal were her wings, which were still folded on her immensely wide back, partially sunken into her expanse. Eventually, she could feel herself begin to rise. The low density gas finally had enough to begin lifting her swollen form off terra firma, the squashed grass beginning to spring back upwards. As she gained altitude, the creatures continued to hover around her, now having let go of her useless limbs.

They prodded and poked at her, letting out noises which could be interpreted as that of laughter. The only other one that didn’t was the one holding the canister, still blankly staring at her, as her entire form creaked and groaned from the excess pressure. Rising further towards the clouds above, the last thing Rainbow saw before she finally passed out from the intense sensation was a cloud of the creatures moving towards her in a locust like swarm, wondering where her friends were.
