Discord's Diarach Dirigible

Evening was drawing in for Canterlot. The shining orb blazing in the sky had arced its way down, only a short distance from the horizon. Warm orange rays bathed the city, glazing the fine white towers and walls into a fiery collage. Fat, wide rays shone through the long glass windows of the castle, casting great shafts across the marbled floor. Something briefly broke one shaft as a tall figure came walking through. Her long, toned limbs practically glowed in the sunset, her porcelain white arms lightly grazing her sides. A long, backless dress clothed them, flowing down her elegant form. Despite the lack of straps present to hold up the front, an expertly placed piece of enchanted boning prevented the strapless piece from rolling down her modest breasts. A thin belt wrapped around her waist, helping to keep the fabric conformed to her slender form. About her neck, reminiscent of a peytral, there was a necklace made of the finest gold; A beautiful purple gem had been inset in the centre, gleaming and sparkling with little effort.

Brushing a few stray strands of hair from her face, the lady's tired, yet satisfied eyes glanced out the window. Directly below were the castle gardens, a large fountain sat front and centre. A great volume of water spat from the middle, the spray creating a kaleidoscope of rainbows that danced about. The blast of water emanated from a statue of a dragon, standing leg deep in the basin of the feature. She smiled at the ornament. The amusing expression it pulled was part of the reason she had it installed on the castle grounds. The goofy smile, the blood red irises, the waving arms…

Princess Celestia stopped, glancing back towards the statue's face. Her eyebrows furrowed as she squinted to try to best take in the details. The eyes were just as lopsided as they always were, the odd red colour vanishing, replaced by a cool grey. “How odd… must have been the light playing tricks on me.” She mumbled, dismissing the oddity as she rubbed her eyes, letting out a soft yawn. Stretching her arms, she sighed in content. “Mmmhhh, that's better. I really ought to use the stretching techniques Luna told me about, she keeps talking about how limber she feels...”

“...Or maybe I shouldn’t just spend all my day sitting on the throne.” Celestia huffed, rubbing her eyes before glancing back through the window. A pair of doors sat in her way; expert carpentry displayed in the smooth, engraved wood. Lighting her horn, the heavy pair swung open with little effort, allowing her access to one of the many ballrooms in the castle. Compared to the grandiose ones used during the Grand Galloping Gala, this place was rather modest, lacking the ornate decoration or the immense scale. So small, in fact, that it had been relegated to an extension of the corridor - with only simple light sources and flower baskets decorating the space.

In the centre of the wall was an immense arched window, inset into the stonework. The carefully cleaned glass shimmered and shone, sending long prismatic shafts of light skittering across the floor. For a second, the light was cut off in sections, Celestia glancing around to catch a look at whoever was flying so low. And yet, she saw nothing. If she was paying attention to the floor, she would have noticed that the light had once again shifted. The rainbow suddenly changing colour, losing its purples and pinks and instead replaced by tones of brown. An involuntary shiver worked its way up her spine. “What is with today?” Grumbling, she took another step forward…

‘Snap!’ A sudden noise echoed throughout the room. It was quiet, but in an atmosphere of near total silence, it was still clear as a bell. She blinked, twisting on the spot, attempting to identify the owner of the sound. Souring the room from end to end, she could see no one else but herself. Moistening her dry lips, she craned her head around once more, before a bizarre tingling entered her hand. Glancing down at her outstretched appendages, she could feel some foreign, indescribably bizarre feeling flooding into it. She watched on, waiting for something to happen. She cocked her head, confusion working its way into her face. “Whatever in Equestria was that? Well, whatever it is must just be all in my head, I…”

Before she could finish talking, her hand suddenly expanded. Like somepony had taken a rubber glove and blown into it slightly, she watched in awe as her fingers puffed out. Lifting it up, she watched in bemusement, turning her palm over. “What in the world?” Celestia muttered, attempting to flex her fingers. Doing so required significantly more effort than usual, springing back to a flat position when she relaxed. Before she could make any more conjectures, a sharp, un-princess-like gasp left her lips as the sensation concentrated in her face. Glancing into the glass, she could make out her reflection, faint as it was.

Like a squirrel packing its cheeks full of nuts, so too had Celestia been afflicted with a pair of round, puffy cheeks. Running a hand along the tennis ball sized swells, she could feel her cheeks squishing and bouncing from the mildest of touch. A groan fluttered from her mouth, the same tightness flooding towards her breasts. “Oh, my… what on Equestria is happening?!” She shouted, her cheeks muffling her voice somewhat. Her modest sized boobs suddenly pushed against her dress. She could feel the cloth pulling tighter and tighter, the blue fabric pushing outwards at a steady rate. A bizarre noise accompanied this, much like the noise made when somepony blows up a balloon. With each long ‘blow’ her breasts become wider and fuller, like someone had suddenly strapped soccer balls to her chest, forcing the dress tight.

Inspecting her now melon sized boobs, the sensation, which was feeling more and more like the flow of gas, concentrated across her belly. In a few seconds, Celesta’s trim middle, kept in check by her regular gym sessions, was replaced by a definitive swell. Though she was conscious of the fact that she wasn’t putting on weight, her rounded cheeks still flushed a deep rosy red. Larger and larger it grew, tightness blossoming from the fabric belt, hugging her waist and forcing the blimping belly into an odd hourglass shape; like a balloon that had been tied around the centre. Her thickened hands ran up and down her gut, her swollen digits tracing the acute roundness of her middle.

Still, the torrent of gas didn’t stop. ‘Sssshhrrippp Snap!’ With a desperate attempt to cling on, the belt failed. No longer confined, Celestia’s blush deepened, her compressed belly swelling out with an almost cartoonish sound. Within mere seconds, her trim middle now resembled a beach ball. Staggering about, her oddly proportioned figure prevented her from keeping a stable centre of gravity. Whatever gas filling her appeared to have a density slightly lower than air. This was made most apparent as each uneven step she made it feel like she was using a cloud walking spell. Still, she had little time to process the logistics of walking, as the tingling sensation travelled to her rear.

With an exasperated huff, her ass puffed up. Her hands grabbed at her globular cheeks, feeling as they pushed back against her hands. Bigger and bigger, rounder and rounder, they bounced around, further straining and stretching her dress. If she was in the right state of mind, she would have realised that her dress should have torn several minutes ago. With the only exception being the belt and a little extra tightness in the fabric, the dress had stretched to comically large proportions. It was more than could be said for her shoes, however. By now, the gas was flooding into every part of her body, becoming impatient with focusing on one area each time.

‘Fwoomp!’ A rush suddenly flooded into her arms. An ever-intensifying force tugged at the limbs as they grew taut and stiff, forcing them to spread further and further out to the sides. A brief tightness was created around her wrists as her golden bracelets strained against the rapid expansion. Wincing at how they dug into her skin, she gritted her teeth as the intensity mounted, then suddenly left as the clasp failed. Like a slingshot they pinged off, clattering to the ground as her thighs thickened. Rounder and rounder, wider and wider, she could feel her body seeming to round out as parts of her anatomy merged. The sound of breaking leather greeted her from below as her shoes were torn asunder, freeing her puffy feet.

‘Crack!’ The chains holding her necklace in place broke, a metallic thunk ringing through her ears as the heavy piece fell. The merging of her form continued, as her back rounded to roughly the same proportions as her belly, forcing the once normal shaped princess into a misshapen sphere. Losing her balance, a small squeak of panic was uttered, rolling forwards onto her middle. Wiggling her legs, her exceptionally wide legs could only graze the floor, sending her into an uneasy bobbing motion, spinning around. Then, with one last puff, the expansion stopped. Blinking, the great monarch of the sun released a breath she wasn’t aware she was holding, shakily letting it out.

Resting upon the apex of her belly, the world around her seemed to be still. Moving through one of the more isolated parts of the Castle, there was very little in the way of other ponies passing by. There was a deafening, heavy silence that fell across the ballroom. Every creak and complaint of her oversized dress, every rubbery like squeak of her body made as she shifted and twitched, her oversized figure seemed near deafening. And yet, as Celestia’s breathing became lighter and calmer, she could hear something else. They had apparently been breathing heavily, a masculine tone was carried in their repeating gasps, almost like they’d been blowing up a…

“Balloon! My personal, life-sized Princess Celestia™ balloon!” The mare in question huffed, rolling her eyes as she watched the serpentine form of Discord slink out from between one of the decorative pillars, his body somehow able to hide behind the thin column. “My dear Celestia, you look positively beaming today, has your day been ‘swell’?” He chortled, slinking closer and grinning as he drank in the fruits of his labour.

“I should have known it was you from the start.” She huffed. Her blush ever present as Discord slowly turned her on the spot, bouncing her lightly as he alternated between his Lion paw and tail tuft. “Discord, please, I’ve had a very busy day today… I’m really not in the mood for your shenanigans.”

“Au contraire my dear Blimpestia, I’m rather hurt you’d accuse me of such a misdemeanour. After all, I’m only trying to ‘uplift’ your spirits.” He said innocently, all the while rolling Celestia around, wickedly smiling as she yelped. Her immense melon sized breasts bobbed about as the ground came up to meet her, then suddenly fell away again as the marble ceiling came into view.

“D...discord, please…” She whined, feeling Discord's hands roll her faster and faster, humming a whimsical tune whilst doing so. In a swift motion, he curled his tail under Celestia, lifting her up with little effort, flicking her up into the air. Landing with a vinyl like thwack, she bounced repeatedly, the world spinning madly. “Oh, keep your head on Celly, I’ll get bored, eventually. And when I do, I promise to change you back… Now let’s see how long I can keep you bouncing in the air. You certainly make for a better beach ball than you do princess.” Closing her eyes and scrunching her mouth, the dirigible sized mare drifted in great lazy arcs as the Draconequus whooped and cheered. Through each bop, bounce and occasional collision with the high ceiling, a new, rather pressing concern fluttered between her partially sunken head.

“If Luna sees this, she’ll never let me live it down...”
