"Mister Dragon? Hello?"

A quiet voice called into the dark cave, barely a whisper echoing back to the relatively small yellow pegasus at its mouth. Her shy teal eyes scanned the darkness within, looking for any signs of stirring at her call. She wasn't particularly keen on pressing further into the inky blackness if she didn't have to, and continued trying to catch the attention of the cavern's sizeable resident.

"Um, I heard you were having trouble sleeping, so uh, I brought something I thought might help." She gestures backwards towards a massive blanket, easily the size of a standard home's room even folded up several times. As it was it towered over her nearly double, and it was a wonder how such a small creature such as herself got it up there all alone. "My friends all pitched in to help me make this nice cozy blanket, since I thought it must be awfully drafty in this old cave..." Still no response came from the depths, but the timid pony kept trying, certain the dragon would answer eventually. "I mean, it's a very nice cave, but a little touch of softness would help any creature get to sleep... "

Eventually, the sounds of scratching about and heavy footfalls emanated from the void ahead, until a large red scaled dragon finally lumbered into view. The great beast sat down at the cavern's edge, stretching his forelegs upwards with a mighty yawn, followed by a rather unceremonious scratch of his side. Fluttershy looked up at the behemoth from behind her long pink mane, slightly intimidated but resolute in her familiarity with this particular creature, the two having met before in the dragon's former home nearer to her own.

"Oh, there you are. I don't know if you could hear me, but I brought you a blanket to help you sleep."She pointed back to the giant block of folded fabric once more. The dragon laid his tired eyes on it, curious to it's origin in his sleepless state. Ignorant to the tiny pegasus' entire existence, he leaned forward to drop his foreclaws to the ground, right over the unseen caretaker.

With a look of fright, the unnoticed yellow pony cowered back and covered herself with her wings as the great dragon's body sped towards her. His front legs came crashing down behind her with enough force to spring her off the ground an inch. After a moment, the shivering speck realized no harm had come to her, and peeked out from behind her wingfeathers, to see the dragon above now walking right over her harmlessly. "...Oh, phew. For a moment, I thought you were going to step on m-mmph!"

Fluttershy had unfortunately not taken the dragon's hind legs into consideration, as one of those giant clawed feet came down right on top of her with a muffled squeak. This finally gave the sleep-addled dragon pause, and he turned around to inspect the ground where he had stepped. There, he found an adorable little yellow pancake, squished against the rocky floor outside his cave. Curious, he reached down with one claw and took hold of one edge, peeling the disk off the ground and holding it up to his face.

The squashed pegasus' eyes spun goofily, having her entire head smashed flat against her her body from above. The pressure had widened her features considerably, with her eyes, ears and nose looking like oversized stickers placed carefully on a yellow circle framed by the pink curls of her mane. Her forelegs stuck out to either side from her chest just below her head, fully extended from the sudden impact. But even still her whole shape was largely circular, with her belly, butt and hind legs having spread much wider than the rest, the two visible butterflies of her cutie mark now the size of some of the larger birds she took care of at her cottage. The primary feathers of her wings were some of the only parts to extend past the edges of her butt, and even then only barely.

It was all she could do to emit a muffled "hmmmmh" in her smushed state, still trying to focus her two-dimensional eyes in order to try and make some sense of what happened. Once she managed to stop her pupils from spinning, she found herself staring at the face of that giant red dragon, who had his unoccupied claw curiously scratching his chin. She attempted to speak, seeking to ask if he recognized her, but it only came out as a series of muffled mmhs and hmms from behind her immobilized lips. In response, (or perhaps lack of), he reached up with another claw and took hold of either side of the pegasus pancake, and gave an exploratory pull.

Fluttershy squeaked as she felt her body suddenly stretching even wider to either side, eyes going wonky again as it was the only part of her expression she could currently change. Like a flat strip of rubber, her painted on features stretched and skewed as the dragon tugged, wider and wider, until a sudden release of one claw made her snap back against the other with a muffled grunt. The dragon chuckled deeply, watching her timid teal eyes spin in circles once more. Carefully, he kept hold on her squished body as he moved on three legs to collect the folded up blanket onto his back, before returning to the depths of his cave.

A shot of flame lit a nearby series of braziers, illuminating the cavern reasonably well. The great red reptile deposited the blanket near his piled hoard of treasure, before sitting down to take a more intimate look at the stretchy new toy he had come across. Fluttershy's eyes hadn't yet stopped spinning from the earlier stretch, but she moaned softly in confusion from atop the dragon's palm. Curious, he flipped her over, to find her one petite backside spread out into a table-sized portrait. Her flanks dominated the upper half of the circle, the pink scrap of hair that was her tail sticking up from the slight divot in the middle where her cheeks met. Her lower hindlegs were similarly distorted below, the bottoms of her hooves now the size of wagon wheels, having taken the most force from the impact against the ground. The dragon poked curiously at the flattened frogs of her hooves, amazed to find them still curiously soft and squishy. In the middle of the Flutterdisk's backside though was the real point of interest; her marehood and ponut, squished into a large flattened teardrop, surrounded by the soft yellow flesh of her belly and butt.

The pressed pegasus managed to once again get a hold of her vision, though she only saw darkness as her face was flat against the dragon's palm. Though very soon much of her remaining wooziness quickly evaporated as she felt a claw pressing into her most sensitive parts, barely an inch behind her head. Her flattened face turned flush, and she let out tiny squeaks of discomfort as the dragon squished and squeezed the lewd spot normally hidden away by her long flowing tail. He pressed into it hard, sending a mounting pressure against the back of her head, once again threatening to envelop her thoughts in a haze of disorientation, but this time with a hint of curious pleasure. When he finally relented, Fluttershy's eyes remained half-lidded, and you might swear there was a hint of a smile on her locked lips.

She didn't have much time to really enjoy it, however, as the dragon then took his entire other palm and laid it on her backside, pressing his hands together to see if he could squash her further. Her lax view suddenly shot wide open as the pressure mounted against her entire form, spreading her body wider and wider like a sheet of soft dough. Her eyes quickly lost focus again, teal irises splaying to tilted edges of her widening face. The pressure became so great that her tongue broke free from her sealed mouth, poking out and quickly being pressed against her chest below as it too spread out into a flat sticker against the distorted parody that once was a normal looking pony.

By the time little bits of yellow started poking out from the sides of his palms, the dragon finally relented, opening his claws to look at the smushed creature he toyed with. Her face now seemed locked in a silly expression, eyes dominating her features and aimed far away from one another, and a little off kilter, reminiscent of the default look of a certain gray mailpony. Her tongue was now a pink sheet of paper beneath her widely smashed snoot. Looking her over, her depth had been reduced to barely half an inch, half of what she was stuck at from the initial stomp. The dragon grinned at his handiwork, listening to the light moans of confusion from the sheet of pony dangling from his grip.

Unfortunately the great beast was not yet satisfied with his plaything's dimensions, and so took hold of her in both claws once again. Holding tight, he once again started to pull them apart, finding he met slightly less resistance after having pressed her flatter. Fluttershy again squeaked and mumbled in bewilderment as her body stretched like rubber, her tender eyes pulled wider and wider as she was somewhat roughly yanked into a new shape. More and more she stretched, now wider than a house as the dragon put all his might into spreading his arms as wide as he could. Her struggled noises came less frequently as any errant thought was pulled from her distending head, unable to think straight as her every limit was strained by the unrelenting force. The dragon fought against her resistance as long as he could, until finally, with his arms at full extension, he lost grip on one side of her and she suddenly snapped back like a rubber band, sending him falling over backwards in surprise.

Rubbing his head from having it hit the floor behind him, the dragon looked down across his scaled belly to find his toy seemed to have lost some of her elasticity. Fluttershy fluttered down on top of him, no longer a disk but a long strip of yellow and pink. The dragon lifted her up, looking at her ridiculously spread face, eyes and tongue all so wide they could be mistaken for hallway carpets. And yet, as wide as she had been pulled, she was still a bit shorter than she was at full wingspan just a moment ago, meaning there was still some give left in her. This gave the dragon an idea, and he rolled himself forward into a sitting position. Turning her face side away from himself, he carefully lowered the scarf-like pegasus to the ground, and set his hindlegs on her lower edges. And then, taking grip once more on her upper half, he stretched.

Fluttershy's immensely distorted body again began to stretch even more, the dragon pulling her elongated body upwards into a massive sheet. She squeaked loudly, the only noise her distorted form could muster, though it soon seemed to be drowned out by the rubbery sounds of her yellow skin expanding. As her head was pulled wider and wider, the thoughts behind it became further muddled and hazy, as she lost all comprehension of what was happening to her. Still the dragon pulled, stretching the once diminutive pony into a tremendous yellow tarp that soon outshined his own towering dimensions.

Looking from the front, you could start to make out the dragon's form behind the unfortunate pegasus, her body stretched so impossibly tight that it started turning a little bit translucent, as her skin was stretched further than any creature would have ever thought possible. Her once petite and kind face now was wide enough to cover the dragon's formidable belly all on it's own, her confused eyes and stretched tongue each now larger than the dragon's own head. Her legs, belly and butt were big enough to land a plane on, those cute little butterflies depicting her talent now massive monsters bigger than any bird she'd ever treated. And still the dragon stretched, not content until his toy was pushed to her very limits, and perhaps beyond.

Finally, the dragon ran out of space to extend himself, his every limb reaching as far as he could muster, pulling the insanely taut sheet of pegasus into an immense rectangle so big she could cover four of the cottage she used to live in, and still have room to spare. If any of her friends were to walk in at that moment, they would be confused at why someone had painted her likeness on a massive billboard. The dragon held his position as long as he could, straining against himself and her remaining elasticity, until finally he gave in and dropped to the floor with a gasped breath.

Instead of snapping back, the yellow cloth that was once a pony gently fluttered down overtop the dragon, covering much of his form like a blanket. Breathing heavily, he rested there for a moment, the wrinkled visage of the fluttersheet covering him staring unblinkingly at the ceiling. Eventually he found the strength to sit up, letting the yellow sheet drape over his arms and body. He smiled as he ran it through his claws, marveling at how soft her body was even as stretched so unbelievably thin as it had been. It was like the finest silk he had ever held, soft to the touch on every part, from the tips of her wingfeathers to the folds of her marehood. Even her eyes and tongue were pleasing to the touch, having their own unique feeling unlike anything he had ever known. With a delighted grin he held the wadded sheet of pegasus close, snuggling his scaly cheek against it.

And then, a thought occurred to the mighty red dragon. He looked over at the rough pile of treasure he had made his bed before now. Pointy ends of gemstones and golden trinkets glinted in the torchlight, reminding him of the pain in his back from many a sleepless night. His eyes drifted to the cloth blanket, suddenly recalling why the yellow pony that now covered his great body had come to him in the first place. He looked down at her, giving a few more curious tugs. To his surprise, her form still had some elasticity in it, a slightly stretchy sheet of the finest silk with the silly face of a pony plastered to one side.

The dragon got an idea.

Standing up, the formerly lonesome crimson reptile draped his new friend across his winged back, making his way to one side of the cave. There he found four sturdy stalagmites, formed ages ago from a spring in the ground above that had long since run dry. Taking the pegasus sheet in his foreclaws again, he flapped her out to straighten her, and laid her down between the four posts. Carefully, he picked up one corner of her rectangular form, and tied it snugly around the stalagmite, giving it a few testing tugs to make sure it was secure. He moved on to the next, only to have his arm pulled back as she didn't seem to reach. The rocky spires were apparently just a little bit further apart than she was wide, even as impressively immense as she was. So, he pulled harder.

The yellow sheet seemed to resist, but with enough force, her ridiculously stretched hide somehow found the ability to stretch even more, creaks and groans of tension again ringing from her form. The dragon secured that corner, and moved on to the lower two. Her pool cover of a face offered no input to these developments as he passed, even as it was lifted up and widened even further by the dragon's strong grip. He took great care to secure the bottom two corners, and then sat back to behold his creation.

It would be a slight misnomer to refer to Fluttershy as a hammock, given how taut she had to be pulled to reach the four pillars. Rather, she looked more like a dragon-sized trampoline, long since unable to do anything about any large scaly creatures that might desire to flop down upon her. Having some of her length tied around the stalagmites, much of her form was now dominated by that goofy-eyed face, its dimensions rivaling that of the dragon by itself now. It was now even more clearly possible to see the cavern floor beneath her, her skin stretched so unfathomably far that she almost looked like a stained glass window. You could even see the contours of her absurdly massive hooves and marehood on the other side of her, right through her silly face!

If she could still make a sound, the pegasus-turned-comforter might protest to the dragon pressing his palms against her cheek, testing the elasticity of his new bed. She might be shocked to see him clamber his great form on top of her, gravity stretching her already impossibly strained form even further as he moved to lay in her center, the soft eyes she used to lovingly cast on her animal friends pulling in to envelop and contour to his every form. She might even be annoyed when after settling in, he had to get back up to go retrieve the blanket she had so thoughtfully brought him, before somewhat more carelessly hopping on top of her, bouncing a good few times and grinding against her helpless tongue as her overtaxed body creaked and groaned. But as he settled in to his wonderously soft and stretchy new bed, and quickly dozed off to sleep, she might find herself happy that she could make one creature so happy after so many sleepless nights.

A gentle breeze wafted at a dark blue nose, eliciting a relaxed sigh from the lunar diarch it belonged to. It was one of the few sounds to come from the serene environment Luna had made for herself; a comfortable perch high in the sky, above even the towering peaks of Canterlot. She rolled over onto her belly to give her cloudlike bed a loving squeeze, to which it responded with a series of quiet squeaks and groans that caused her to giggle in bliss once more.

"I must thank you again for this opportunity, dear sister. I've not been this relaxed in centuries."

Celestia was unable to give much of a response, given her predicament. The gentle hissing of the hose firmly planted in her mouth was the most noise she was capable of making at the moment, besides an errant moan from behind it, or squeak of pressure from her overstressed body shifting as it continued to grow. Looking down over the seemingly endless white expanse of her own body, she wondered just how much larger she was going to get.

The solar princess thought back to the conversation that started all this; her younger sister assured her it was only a single tank, and a small one at that. She had many questions, first and foremost where the blue alicorn had picked up this particular... interest, especially after having been gone so long up until recently. Moreso than that however was the idea that what she proposed was even possible. Luna assured her it very much was, having observed the phenomenon several times among the populace, most notably from a pink earthmare the two knew very well. That seemed enough to soothe her concerns, and she agreed, much to her sister's delight. After all, it was such a small orange tank, smaller than the ones commonly used at birthday parties. How much helium could it contain?

Quite a lot, as it had turned out. She wasn't sure if it was magical in nature, or some kind of strange science she had been unaware of, but regardless; here she was, larger than the castle she once called home, and growing still. What's worse is she was pretty sure the tank was still somehow only half-empty, meaning she had a long way yet to go. Her two soccerball-sized cheeks squished against either side of her head flushed red again, as she once again remembered how... exposed she currently was. Luna had picked a largely unpopulated valley on the northeast outskirts of Ponyville for the event, but at the height she'd drifted to, not to mention the size she was, it occurred to her that one wouldn't even need a telescope to see her massively blimped netherparts currently squeaking around somewhere far behind her. Not a single inch of her most private of places remained unbloated; from her quivering overinflated tire of a ponut, to the squeaky pink queen-sized bed of her marehood, all the way down to the puffy, sensitive nipples of her overblown crotchtits, each breast they sat upon liable to serve as a hot air balloon apiece. Even her hind legs that currently framed these expanding lewditites were massively oversized; the two suns of her cutie marks had stretched so wide that an average pony could lay down in the middle of one and not be able to touch any side with their legs, no matter how hard they reached. The only movements she could still make in protest were the pitiful wigglings of her own four hooves, spread far and wide from one another by the immense quantity of helium her body fought to contain.

Though, to be honest, she did still have her magic, in case things got too out of control. Her horn remained unbound, as a symbol of trust between the two cosmically intertwined mares. A tug from her golden aura would be all that was needed to remove the hose from her lips, as no tape or ties had affixed it in place. She could stop this at any time, really. So why didn't she? Was it just the promise she made to her sister, even though it's obvious she had been selective in her telling of truths about it? Did she suddenly become curious just how much she could take? Or did the experience simply bring forth the notion that she actually kind of liked it? Paradoxically, the sensation of having every inch of her alabaster coat stretched so phenomenally far in all directions was quite nice, and the panic that was once caused by an inability to move or control herself gave way to the realization that she didn't need to. Her lunar sibling was there with her, and with it a confidence that she wouldn't let anything too strange or terrible happen to her.

At least, that was how she felt until she noticed a change perpetuating across her enormous body. The rate of expansion seemed to have slowed down somewhat, yet the flow of helium from the hose had not, causing the pressure inside to start to build. Had she finally reached her limit? The tank still showed no signs of stopping any time soon, but if it kept forcing more of it's contents into her, she may not turn out to be as sturdy a container as she had once believed. Maybe this had gone on long enough.

Celestia mmphed and hmmmed against the hose several times, trying to call her sister's attention. She got little response, other than the gentle breathing she could just barely make out somewhere behind her head, and... snoring? Luna had fallen asleep! What was once a serenity mirrored by her now snoozing sister, had started to give way to a growing panic. If she couldn't get the hose out, she might... No, stay calm. There's nothing holding the hose in her mouth besides her own lips pressed against it. All she had to do was open her mouth, and... just gotta open… OPENNNNNN…

Apparently Celestia's mouth was held shut by her own bloated cheeks and burgeoning neck. This was less than ideal. No matter, as she reassured herself, she still had her magic. The long ivory implement of countless sunrises and sunsets began to glow golden, as a similar patch appeared on the hose in front of her squished snoot. It lifted the deliverer of immense quantities of gas aloft, and started to move it further away from her gaze. It quickly met resistance, very much not wanting to come out. Her eyes squinted in strain as she tried pulling harder, but to no avail. Surely it wasn't stuck that hard! Was it covered in superglue or something? ...No, she started to realize what the problem was; her own magical grip was heavily weakened by her primarily gaseous state. She had already felt somewhat lightheaded this entire time from all the helium entering her body, but now the effect seemed to be intensifying, making it that much harder to concentrate on her telekinetic aura. Why was it getting so hard to keep a clear head only now? Was there something else in the gas? And had her ears always been that puffy?

...Her ears? Her ears were growing! Sounds suddenly became muffled and distant, as the lighter-than-air substance caused her ears to swell, sealing the orifices shut behind a wall of squeaky white flesh. It seemed that with little other places to go in her own body, the pressurizing gas had started invading her very head! Celestia watched in astonished fascination as the once dainty seashells that framed her flowing astral mane slowly billowed outwards into overinflated footballs. The sight momentarily made her completely forget about her critical task of removing the hose, until she managed to shake off a bit and resume concentration as best she could. But concentration was in rapidly diminishing supply, as she felt a heavy pressure against the back of her head growing more and more, causing her aural grip to falter, and finally fail completely. The hose fell back to her neck with an unceremonious "poont"; the echoing sound of it striking against the hollow surface behind which incomprehensible volumes of pressure remained building in perpetuity.

The overwhelmed regal let out a muffled whine at her failure, worry creeping into her expression as she had seemingly run out of options but to wait and hope for the best. Her eyes darted around in a mild panic as she focused on each growing aspect of her features she could still see; her beachballed cheeks, the puffy bedpillows of her ears... she swore even her horn was starting to thicken up. And then she found she couldn't focus on any of these parts at all, as her vision suddenly screwed in strange directions she had never been able to look before. Her gaze went wide, each confused pupil pointed opposite from the other and into the sky above. Her bewildered moans conveyed the overwhelming pressure she felt pressing into her head from all directions, until finally, with one last startled "hrnk", the pneumatic princess's very own eyes suddenly ballooned outwards from her overtaxed head.

Her vision understandably grew fuzzy as the helium forced its way inside her bulging optics, growing larger and larger against the now clearly too small frame of her face. But even this new outlet was not enough for the relentless pressure, as soon enough a small strip of pink poked it's way out of her mouth, beneath the hose still pumping into her. The offending tube began to lift upwards little by little, raised aloft by her swelling tongue. As the gas continued to seep into every impossibly tight part of her face, the ageless diarch looked less and less like the pretty mare she started the day as with every passing second. She had quickly become unable to see clearly out of the silly looking balloons she once called eyes, her purple irises splaying further and further apart by the second. Even the ivory spire of her horn above had turned puffy as it too grew larger, confirming her earlier suspicions, though she was in no state to reflect on the fact anymore. Her mind grew increasingly hazy as her head filled up more and more with the encroaching substance, making coherent thought more of a dream than reality.

Bigger and bigger her visage grew, as the ceaseless flow of gas pushed every limit of her immensely stretched face to the brink and then beyond. That tiny strip of pink her tongue had been just moments before now looked more like a pillow a pony might find comfortable to sit on, wedged between the two overfilled beanbags her cheeks had become. The slender, spiraled wand on her forehead had widened out into a fat, round cone, squished against the two bloated party balloons her eyes had become, creaking and wobbling as they saw fit to to inflate ever larger seemingly without limit. Confused, distant murmurs were all she could manage to make at this point, nearly drowned out by the squeaks and groans of her face as it continued to grow and grow into a mass of bulging white, pink and purple cushions. And then, with one last push...

The hose popped out of her mouth with a gentle poik, her tongue having finally grown too large to allow it any more room in her jaw. The hose snaked its way down her neck and chest, disappearing into the sky beyond as the dangling tank pulled it all towards the ground far below. For a moment, the air fell silent, save for the soft creaking of the unbelievably massive blimp of an alicorn princess drifting through the clouds.

At long last, Luna stirred, relaxation broken by the sudden absence of the ever present rhythmic hissing of the hose. "Mnnn... Tia...?...Forgive me, I must have dozed off. ...Tia?" Confused by the lack of her sister's response, the lunar royal lifted her head, pawing at the squeaky white surface she laid upon with her forelegs. Looking around, memories of the situation slowly returned to her, and she bore a relaxed smile as she dropped back down to embrace the familiar bed with a contented sigh. Though after a moment, a more morose expression came to her, the meaning of the new silence growing apparent. "I suppose that means the tank finally ran out, then? A shame, I was just starting to really get comfortable. ...Ah well, I suppose we never set any time limit on how long we'd spend up here after the tank expired, did we? Mayhap we should simply wait for the helium to eventually leak out on its own? It surely wouldn't take more than a day or two, don't you think, sister? ...Tia?"

Though she was aware of her sister's diminished response capability, she at least expected to hear some mumblings of protest, yet the solar sibling remained silent. Once the starry-maned alicorn stood up fully and bouncily strode the distance to her once-willing airbed's frontend, the reason for this became clear. Luna gasped in shock at the sight. "Celestia! Your face! You... you look... ridiculous!" Giggles erupted from the amused noble, unable to contain herself at the hilariously distorted appearance of her once refined and demure sister, now a comical parody of her former self. Luna bounded happily around to the front of the silly pile of balloons Celestia's face had become, sitting in front of it and unfurling her wings to keep from tumbling down the slope of her chest beyond. She leaned down in gleeful curiosity, making a few playful bats at the pink squishy balloon sitting in front of her, which jiggled about fantastically with every thump. She giggled once more, and was only able to resist the urge for a moment longer before dropping her head down on the overstuffed pillow of the sun princess's tongue. Despite the undoubted pressure within it, it was by far the most comfortable thing she had ever laid upon, and she brought her forelegs up to cuddle into it in delight.

"Aaaahhh... I must say, this is the best you've ever looked, sister. We should definitely do this more often," Luna remarked with joy, reaching one of her forehooves up to plant a boop on her overblown sister's comparatively tiny nose. In doing so, she accidentally brushed against one of the wobbling spheres of the living blimp's eyes, to which she quickly sat up and retracted her reach abruptly. "Oh! I'm sorry, I didn't mean to poke you in the eye like that... Did it hurt?" Luna waited pensively for a response, before she realized her plaything was very likely in no such state to do so. She shook off the worry, and suddenly found very odd thoughts filling her head. She knew you weren't supposed to go feeling around on another pony's eyes like that, anypony knows that just from accidentally doing so to themselves. And yet, this was far from a common situation, possibly even one heretofore unknown to ponykind. She figured Celestia was largely mentally checked out at the moment, so... would she mind? Wait, why is she thinking this hard about feeling up her sister's eyeballs? Was she really that depraved? Surely not.

And yet... in that brief moment of contact, she had felt something unlike anything she had felt before, perhaps because it may have never existed before now. That barest touch had awakened a curiosity deep within her being, one that she found irresistible to explore. Luna looked upon her sister's billowing eyes, each orb easily twice the size of her own head. The light of the sky above still danced lovingly on her widely stretched purple irises, glinting invitingly as they softly squeaked against one another from small, unconscious movements of the creature below. Tentatively, the moon princess reached a forehoof towards one, her boldness growing with each closing inch. "Sorry about this, Tia…" she gave as one final apology to her object of desire, as her hoof daintily squished into the shining white side of the ocular balloon.

It was, without a doubt, the softest thing she had ever come in contact with. Luna ran her hoof slowly across the surface of the inflated eye, marveling at how it could be so comfortable to the touch, even as unbelievably pressurized as it must have been. It was taut, surely, but still had the right amount of give to invite the most intimate of cuddling. Unconsciously, she inched her seated backside closer and closer, until the previously enjoyed balloon of a tongue was sufficiently squished between her hindlegs, pressing into her own darkened nethers. It was the final push she needed, and at last giving into her passion, Luna promptly flopped forward into Celestia's blimped bed of a face.

Luna was in heaven. The unbelievably soft balloons of her sister's eyes caressed either side of her face as she nuzzled into them with wild abandon. She groped, squeezed, and smooched the beautiful bubbles of vision many a stallion had likely found themselves lost in even when they were normal sized. Her hindlegs straddled the nearly as soft pink balloon poking out of the air-burdened royal's mouth, long since having sealed her lips shut to prevent any words from escaping, were the mind that controlled them even able to do so. Unconsciously, her moon-bearing hips began to buck, rubbing herself against the squishy masses of that wondrous visage, suddenly lost in the mounting pleasure she could have never dreamed of experiencing. She was surrounded on all sides by the most amazing sensations, every facet of Celestia's face now an enrapturing alcove of squeaking, creaking bliss. This was the greatest she had ever felt from contact with the solar ruler, in their millenia-long relationship of a thousand intimate interactions, the only two either would trust with themselves in that way. And despite the empty headed balloon her sister had become, Luna felt that deep down there was some spark still in her that felt the same.

After what seemed like an eternity of unfathomable bliss, Luna's motions abruptly seized up, and she held the wobbling balloons of her sister's eyes as close and tightly as she could, the squeaking pillow of ballooned tongue below firmly squeezed between dark blue hips, pressing into every tiny crevice of Luna's being as the stars of her mane burned brighter than they ever had before. Luna cried out in absolute ecstasy as waves of pleasure rocked her to her very core, outdoing more than a thousand years of euphoric moments in one glorious, unstoppable minute.

Her stars soon dimmed as the afterglow set in, as Luna managed to turn herself over onto her back, settling into the same spot she had just spent the time of her life. Even in her weary state, the feeling of those luscious white and purple orbs above brushing against her sensitive ears sent shivers down her spine and unleashed several sets of aftershocks, interrupting her heavy panting with clipped moans of more pleasure. Eventually, her body managed to calm down enough to allow her a moment of clarity, upon which she sat up, still seated on the glistening tongue of her bloated sister. She looked back at the bulging mass of balloons Celestia's face had become, and reflected on what had just happened. One thing soon became very clear to her.

She needed more. Much more.

Pulling herself to her hooves, Luna carefully trotted around one side of the cradle of bliss she had just enjoyed, once more regarding her airheaded sister as a conversation partner. "So, I know we only agreed to one tank, but going by the measurements I was given by the pony I got it from, I think this one might have slipped out before it was able to fully empty. And we can hardly call that a full fulfillment of the deal, now can we?" Luna bounded across the taut-yet-still-bouncy surface of her sister's neck, now easily wide enough to fill either of their entire bedrooms on it's own, to the moon-marked saddlebags she had brought with her for this journey. "So, in your absence of clear thought, I feel it's my duty to make this decision for the both of us." After a short period of rummaging in the saddlebags, the crafty blue princess pulled out a second orange tank, just as big as the other one; untapped, and completely full. "After all, you've never been one to duck out of an agreement between us like this, have you, Tia?"

With a crouch and a leap, Luna took flight above the blimp she once called a sister. From an aerial vantage point, she was able to take in just how much bigger she had become since last she looked. If Celestia had been a blimp before, she was easily within a class of her own by now. The two suns on her butt that once were barely larger than a hoof placed atop them, now stretched into a tremendous bulging daises, that one could host an entire concert of ponies on each of. Her belly reached down far below, easily outshining the mountaintops that it drifted nearby. Circling around to the far end of her, the lust-consumed princess spotted her target. Bulging skyward above Celestia's expansive, building-sized balloon of a marehood, stood her immense pink ponut; billowing upward like a beautiful rising hot air balloon, the comparatively small pucker in the center inviting any that wished to explore it's depths.

The blue alicorn grinned as she set herself down atop this mighty expanse of balloony flesh, sinking into it slightly as her weight came down. Despite all the pressure contained within her sister, these certain sensitive areas remained soft, still with the right amount of give to allow for an endless bounty of pleasure. Pleasure that Luna had already explored in depth earlier in the day, but even as wonderful as these blushing fields were, they could barely compare to the wonders more recently discovered around front. Another shiver shook through her as she thought about it, and began to bound towards the massive cushion's primary entrance. She paused at it, sensually tracing a hoof around the infolded entrance, idly wondering if there was enough spark left in that blimp of a head her sister had to still blush at the sensation. It was a passing thought, and so she quickly took to work. Sitting down as she took the tank under one arm, she set her other hoof on the valve, and spun it all the way open, twice the rate of release of the previous tank. Caution had long since been lost to the winds, as she admired the sputtering valve one last time.

"Sister, I'm going to make you the biggest princess Equestria has ever seen!" With an almost deranged smile, Luna reared back, and plunged the hissing tank deep into her sister's  inflated ponut. She gave it a good few shoves, burying it deeper and deeper, until only the bottom surface of the tank was visible in the burgeoning crevice. The loud sound of rapidly escaping helium became muffled and quiet, as every last molecule of the gas was made positively sure to stay trapped inside the new container it happily filled. Almost at once, the entire surrounding area of Celestia's backside began to thrum with motion, once again beginning it's steady and unrelenting march outwards. Luna had to cradle herself to contain her overflowing glee at the reaction, already imagining what was going on at the front. Planting one last kiss on the vibrating pink surface she sat upon, the unrestrained princess took to the skies once more.

With a joy normally reserved for that pink earthmare that may have inspired this whole ordeal, Luna sailed over the rising solar peaks of the sun princeess' butt cheeks, mind racing with thoughts of what was to come. She was so overwhelmed by these thoughts that she actually had to cover her eyes as she flew, lest she spoil the surprise until she was in the proper position for observation. Navigating as best she could while flying blind, the relative speck of an alicorn positioned herself in front and above the growing form of her sister. The various creaks and groans of expansion below tickled her ears, and she bit her lip in anticipation. She opened her eyes, looked down, and nearly fainted.

What was once the pretty little face of Equestria's most beloved ruler, had now become nothing more than a massive, wobbling, goofy looking bed of taut, creaking pillows. Each of her eyes was easily twice the size it was before, bigger than even the largest beachball they had found to play with, and only growing larger. Her well loved tongue looked like it'd be more at home as the cushion of an overstuffed easy chair. And even her cheeks looked more like trampolines than something you'd expect to find framing a regal visage. Barely able to contain her pounding chest, Luna gave one last appreciative look from above, and spread her legs wide as she folded her wings shut, leaving gravity to pull her down towards her most primal desires.

The force of her impact pushed her deep into the crevasse of the blimped face, pulling each wondrous part down momentarily, squeezing them all together and enveloping the bliss-drowned princess in the most amazing squeaky embrace for all but a moment, before the action rubberbanded and sent her flying back up and out. Ecstasy wracked her entire frame as she sailed, unable to or simply uncaring to try and change her trajectory. She shortly came back down atop the most exquisite of cushions, one of Celestia's own blimped eyeballs, the purple of her iris just able to peek out from beneath all edges of Luna's spread prone frame. She squeezed, caressed, and grinded herself against the still impossibly soft surface of just one of the massive spheres of vision. Her own mind could barely comprehend the levels of pleasure as her sister's eye continued to grow beneath her, pressing itself into every nook and cranny of her blue underside, squeaking and groaning as it billowed higher and higher beneath her. Almost unconsciously, Luna slid down one side and found herself wonderfully nestled between both of the immense weatherballoons her sister had once used to see. Despite everything that had happened, she could still barely believe that her sister's eyes could feel this wonderfully comfortable when blimped so fantastically huge.

Through her haze of euphoria, Luna could feel beneath her own diminutive behind, that even the surface of her sister's forehead had started to balloon, as the ever-invading helium forced it's way into her growing, squishy head, that could nary contain a thought about her predicament any longer. Her perception of the world around her was long for naught, with eyes approaching the size of overinflated parade floats, ears that could serve as beds for ten ponies each, and a tongue that would have trouble fitting into a two-cart garage. The only thing bouncing around in that massively ballooned head of hers was the tremendous quantities of gas that pervaded every conceivable inch of her interior, forcing every impossibly inflated part of what she once called a face unrelentingly larger. And with no magic from that nearly spherical blimp of a horn bobbing around above her burgeoning eyeballoons, there was no stopping it from continuing as long as that deceptively tiny tank could hold out. With every second that ticked by, her mind grew as hollow as empty as the rest of her; just a gargantuan, unstoppable, alabaster balloon that once considered herself a princess.

As the inviting comfort of Celestia's own inflating forehead grew, Luna wriggled every which way she could, adoring every second of it. The head below her was already easily rivaling the average house in volume, and the great expanding eyes above them even larger. Each element of Celestia's billowing face could now be seen with the naked eye from miles away, the immensely stretched purple circles of her vision aimed to the stars above without control. Shakily, Luna managed to convince herself to crawl forth from the envelope of unmatched comfort, pulling herself up onto the bloating snoot that she had covered entirely with a hoof such a short time ago, now large enough to support her entire body. But it was still no match for the enormity of pink balloonflesh that laid out before her; that tongue that she had so lovingly ridden in the first encounter was now large enough to land an entire fleet of pegasi on, without a single one having to rub shoulders. Looking to either side of her, she could barely make out the curvature of her sister's cheeks, each one large enough to fill an entire city block of Canterlot, but only for a few moments longer as they too continued to bloat and inflate with every other part of Celestia's impossibly massive frame. Luna rolled over to look back up at the enchanting towering eyeblimps, still wobbling and creaking against one another as they continue outward and upward unhindered by any sense of logic or reason. With one last loving caress to the adored spheres above her, Luna closed her eyes to finally rest her weary body.

"I must say, Tia... I feel downright selfish keeping so much of you all to myself like this. Perhaps we could set up some kind of... Princess Appreciation Day? I do believe ponies and even dragons from all around would gather at the chance to bounce upon such a marvelous princess's face. Though we may need to add a little more mass to you... we don't want anypony feeling left out, after all. You don't mind, do you?"

Luna giggled, patting the taut blimped nose below her with a few hollow thumps. Celestia wouldn't mind at all, even as her massive form began to outshine the entirety of Canterlot itself. Not even if each of her creaking, groaning eyes became larger than the whole of the castle she once lived in. Nor if her tongue alone broke every record the country had for Largest Inflatable Object. She'd pay these details no mind at all, having a head that for now only served useful as the world's largest trampoline.
