Requested by  Cetas, this story contains dinosaurs - dinosaurs who happen to be inflatable, and who happen to grow very, very big, those last two things being par for the course for him. Don't know if he's done much with dinosaurs before.

Being chased by a pack of velociraptors is generally the last thing that most dinosaurs would want. Unfortunately for a particular pachycephalosaurus and a particular parasaurolophus, this was exactly what was happening to them. Running as fast as their legs could carry them, the two crashed through undergrowth as they inexpertly weaved in between the trunks of towering conifers, raptors practically snapping at their feet with every step. The parasaurolophus’ heart pounded, chest heaving in and out as its stamina slowly dwindled. The pachycephalosaur was in a similarly poor state, both dinosaurs having been run ragged by the raptors’ relentless pursuit.

The forest they ran through abruptly ended, replaced with dead, rocky ground. The parasaur overtook the pachycephalosaur, feeling a small amount of relief - it would be easier to outrun the raptors on flat terrain, with no obstacles to trip over or run into. The relief vanished as the trio of raptors emerged from the verdant forest, screeching in anger as they barrelled towards their prey. Vibrant seemed to almost glow under the harsh sun, a beautiful display that would have attracted the attention of both the parasaurolophus and the pachycephalosaurus, were they not being threatened by the raptors’ wickedly sharp talons.

The parasaurolophus came to a sudden halt, feet kicking up dust as she stopped as quickly as she was able. She was at the edge of a cliff. She had emerged from the forest, and had cornered herself. Looking over the edge of the cliff, she saw a large pool of black-brown liquid; tar! The drop didn’t seem high enough to kill her outright, but if she fell into that tar pit she’d be dead for sure!

She backed away a few steps, turning around as she did so - and let out a cry of alarm as the pachycephalosaurus barrelled towards her, too fast to stop in time to avoid ramming into her. Her feet left the edge of the cliff and she fell backwards, towards the tar pit below. As she fell, she could just make out her fellow dino's face, seeing the shock in those eyes - and the dread in them, too, as the raptors began to advance, hoping their last remaining prey wouldn't also fall off.

She sank beneath the surface, but the slow death she expected did not come. Though the thick tar filled her lungs, she felt no discomfort at all. Taking in an experimental breath left her puzzled - how could she still breathe? Why was she not choking to death? For that matter, how could she still see; how were her eyes not burning?

As the parasaurolophus pondered the answers to the questions she had, her feet settled on the floor of the tar pit. Looking about, she found that the tar offered almost no resistance, as though it was no thicker than air. Thoroughly confused, she turned her head this way and that, trying to find a way out of the pit. Her vision was completely obscured, though, and she found herself unable to see more than a few inches in any direction.

Snorting in frustration, the parasaurolophus decided that picking a random direction to walk in would eventually lead to her finding an exit, and, after several moments, turned to her right and began to move. She knew that she was safe from the raptors for the time being, but what would happen when she got hungry or thirsty? What would happen to the pachycephalosaurus that had ran alongside her?

Her thoughts ceased, however, as a strange, tingling sensation started at the very tip of her tail. Slowly, it began to move up the appendage, which swished about at the unexpected feeling. It wasn’t unpleasant, but neither was it a feeling that she welcomed. It began to spread from her tail to the rest of her body, working its way inside of her until all of her limbs were abuzz with the sensation, her insides tingling along with them. She tried to let out a snort of discomfort, but found herself unable to - the feeling was so intense that she could do nothing other than stand there, surrounded by tar, and revel in it.

Her eyes shot open when the feeling subsided, only to be replaced by another - something spreading throughout her body, changing it into something other than flesh and blood. Unlike before, this feeling was pleasurable; the parasaurolophus wiggled about as the feeling spread to every single part of her body, all of her changing at a cellular level. The transformation took only a few seconds, but by the time it was done, the parasaurolophus was something entirely different to what she had been before. Looking at herself, she could see that even in the inky blackness of the tar, her body shone and sparkled with a dim light, and she could hear faint squeaks with every motion of her changed body. Not only that, but her body felt… softer, somehow. The parasaurolophus knew that she was no longer made of flesh and bone, but she had no way of knowing what she was now composed of.

The pleasurable feeling quickly returned, however, now so intense that the parasaurolophus could do little other than squirm in place, chuffing and huffing in reptilian bliss. Her eyes widened once again as she saw the floor pull away from her by just a bit, seeming to shrink my some tiny amount. The parasaurolophus cocked her head to one side in confusion, batting her eyelids and swishing her tail before, with a quiet squeak, the floor pulled away again, her insides tingling deliciously as it did so. She poked at the silty floor of the pit with a toe, before the feeling overwhelmed her, her tongue flopping out of her mouth as she began to slowly, steadily pump up and up, bigger and bigger. Before, she had been about average size for a parasaurolophus, but now she was huge, at least one and a half times as large as the tallest member of her species she had ever seen - and still, she grew, rubber hide squealing wildly, stretching longer and thicker as she inflated to sizes she had never even dreamed of reaching.

Her head broke the surface of the tar pit in a matter of moments, and her latex hide sang as she expanded clear into view for both the pachycephalosaur and the raptors hoping to make a meal out of her. The hard-headed dino was right up against the edge of the cliff, likely about to fall, and let out a little roar as her raptor opponents shrank back in fear and she regained her footing, advancing on them - only to turn around as she was engulfed in shadow, and openly gawp at the growing inflatable dinosaur that suddenly loomed over them all like a T.Rex over its wounded prey. The parasaur let out a snort, and prodded at her body, feeling her squeaky hide deform slightly around her poking finger-like toes. She licked at her rubbery lips with an equally rubbery tongue, the motion producing a symphony of squeaking squeals, and let out a rumbling sigh that shook the ground the other dinos were standing on; her tail swished back and forth through the air, the motion producing a single, prolonged squeal.

The largest raptor seemed to regain some of its nerve, and ceased quivering, standing tall over its two comrades. It wiggled in place as it sized up the overgrown parasaur, baring its teeth. It charged, and the pachycephalosaurus moved away to avoid getting bowled over by the feathered fiend, her clawed feet coming perilously close to falling off of the cliff. The raptor leapt into the air, sharp talons ready to be used - but with an indignant shriek, it simply bounced off of the parasaur’s light brown latex body, flailing its feathered limbs as it fell down into the tar pit below. The parasaur felt a strange feeling well up within her throat, like something begging to be released - and release it, she did:

“Hee!” she giggled, tilting her head cutely as her tongue flopped out. “That tickled!” She didn’t know what she had done, as she had never actually spoken before, being a dinosaur, but it felt right somehow. She wiggled about, hide squeaking as the trio of little dinosaurs down below continued to gawp, shuffling backwards as her hide pulled tight, and her body blew up another ten feet, on the spot! Could the contact with the raptor have done it? “Ooh, growing feels so good! Mmm, I wonder if I can make myself grow more…”

Before she could follow up on her growy desires, however, the parasaurolophus felt a tingling feeling at her feet that quickly morphed into… Into the feeling of latex being dragged over her rubber skin. She gulped and looked downward, fear appearing on her muzzle as she saw the overconfident raptor - now, it was made of the same rubbery material as her, and ballooning larger with each huffing breath, latex feathers all ruffling and squeaking wildly. The parasaurolophus stumbled a few steps away as the raptor’s head rose past the cliff, steadily getting closer to her own. With what little space there was in the tar pit, the two inflatable giants were forced into each other, bodies squeaking loudly even as they readjusted themselves, the raptor showing off her rubber teeth and letting out a growl as she pumped up, and, and up, her growth stopping when her feathery form just about outmatched the parasaurolophus.

The raptor leered down at her prey, her growl so loud as to cause the ground to rattle and shake. She eyed the teeny-tiny pachycephalosaurus down below, who shrank back even as the raptors behind her began to regain their confidence. The growl the raptors let loose, however, was changing; it became higher in pitch and more feminine - though seemingly louder and more booming, as she, like the parasaur before her, began to speak. “F-feels… Good,” she grunted out in a feral manner, running her tongue over her teeth with a whining squeal of rubber on rubber. “Mmm, good! Want… Bigger! Want…” She trailed off as her attention turned once again to the parasaur, and her grin became more predatory than ever before, showing off every single one of her rubber teeth. “...Want prey inside of me!”

The raptor lunged forward with a bellow, mouth open wide; she easily locked her teeth around her prey’s neck, and bit down, hard; but what she had expected to happen - the ripping and tearing of flesh and spraying of blood - didn’t. Not only were her rubber teeth too round and squishy to do any harm, but the parasaur’s latex skin seemed to be all but impenetrable! Letting out a giggling snort at the strange feeling of being bitten by inflatable teeth, the parasaur wiggled about - before suddenly bursting larger, her expanding bulk growing too large for the raptor to grip with her mouth. Her erstwhile predator fell from her body with a splash of tar, and began to be pushed back by her growing bulk.
Down below at the cliff’s edge, the pachycephalosaur backed up as the raptors once again began to advance on her, their confidence regained after seeing their leader grown to such an immense size and level of power. The hard-skulled dino looked left and right, seeing no way to escape, and no way to fight them, looked down at the bubbling tar pit below - and then up at the two latex behemoths, one of whom was growing even more massive, the parasaur’s light brown form pushing back the raptor with her growth alone. With one last look at the raptors advancing on her, the pachycephalosaurus jumped off of the edge of the cliff; with the two inflatable giants so close, however, she ended up sliding down the parasaur’s skin to reach the tar pool, producing a single, torturously long squeal that seemed to echo slightly. With a quiet splash, she slid below the surface of the tar, unnoticed by the two inflatable titans up above. The two raptors, knowing what was about to happen, jumped down after her, both eagerly awaiting the coming metamorphosis as they fell towards the bubbling tar.

As the parasaur stopped growing, she took in a massive gulp of air that only served to pump her up in size a tiny bit more, releasing it with a sigh that shook the ground with its volume. “Oooh, I love that feeling! Love it, love it, love it!” The parasaur squealed as she beheld the shrunken landscape around her, her body so immense that she could barely made out individual details down below - she was simply too high up. The raptor, now barely a fraction of her immense size, openly gawped at the mountain-sized parasaur that loomed rather thoroughly over her, and over all. “You… Big,” she boomed as she stumbled to her feet,”Bigger,” she growled, almost salivating at the thought of such size. The raptor ruffled her inflatable feathers with a symphony of squeaks, thoughts of bigness filling her mind. “Bigger… Need bigger!”

At that moment, however, the parasaur happened to look down at her seemingly-tiny foe, the pachycephalosaur and the other two raptors too small for her to even see, despite their rapidly growing stature. She smirked, happily and victoriously, lowering her gigantic head down to her erstwhile assailant so that they could talk. “Mmm, I think I’m a bit too big for you to handle,” she giggled out, the sound shaking the earth and causing dinosaurs miles away to look about in confusion. “But,” she continued. “You’re not too big for me to handle!” And with that, she lifted up a clawed foot, so large it blocked out all light below, and brought it down onto the raptor with all the force she could muster.

Though she did not know it, in addition to harmlessly crushing down on the largest raptor, her foot had also trapped both the pachycephalosaurus and the two raptors she had been itching to fight with her newfound invulnerability. Deep inside all four trapped dinos, a quivering, shaking feeling started. It swelled and swelled into a rumble, and then into a deep, shuddering, quake, to the point that even the parasaur, so large and so far above, began to rattle and shake from it.

Forced into the ground by the squeaky reptilian footpaw above that deformed around her body, the lead raptor could do nothing but huff and puff, breathing harder and harder as the power bubbling up inside her overwhelmed her. “B- B-big,” she mumbled breathlessly as her eyes rolled back into her rubber skull. She could scarcely think, scarcely breathe, all of her attention of the power inside her that was gathering, gathering, gathering-

With a wordless roar of growy bliss, the Alpha raptor utterly exploded in size. Whereas the parasaur’s growth spurt had been a steady surge of size, this was an explosion of rubbery, squeaky bulk. And through it all as she pumped, inflated, and expanded upwards and outwards in every directions, getting bigger and bigger and bigger at a maddening speed, the raptor could only manage to speak a single work: “BB-BIII-IIGG-RR-RRR-RRRR…” Her berserk growth spurt sent her rocketing upwards, soon passing an entire mile in size - then two, then four, as the parasaur that had so foolishly pinned her was flung off of her growing form and carried along by her inflating toes. The duo of smaller raptors and the pachycephalosaur were similarly carried along by her growing body as it inexorably inflated larger, larger; even as the very tips of her latex talons gouged out trenches hundreds of feet wide and deep into the earth, the Alpha raptor had only one thing on her animalistic mind: More. MORE. MORE!

“YESSS,” she bellowed even without meaning to, her inexorably growing body so huge that she blotted out any possible site of the horizon, of the sun, of the sky. “I BIG! BIGGER! BIGGER THAN- THAN-”

Even as large as the Alpha raptor was, her toes alone big enough to cover any mountain range, she still paused as she felt a tingling down at her feet. Opening her maw wide, she growled lowly, shaking the planet as she peered downwards. However, she was simply too large to see what was happening. The pachycephalosaurus from earlier had been attacked by the two smaller Beta raptors as the three scrambled madly to escape from the growing Alpha’s toes and claws, and she had been charged up to such a degree that she could barely even think. During the fight, the raptors had been similarly charged up, their multi-hundred feet tall bodies shuddering terribly, though not to the extent that the pachycephalosaurus was; she was shaking so quickly and violently that it was more like she was vibrating!

“Aahh,” she grunted, tongue slipping out of her mouth. She bit down on it in concentration, the motion producing a small squeak. “Haaaah, aaaaah!” She breathed in and out, gulping in huge mouthfuls of air before letting them back out in a rush that disturbed the natural flow of the wind. Her bellowing breaths were just about audible to the titanlike raptor that towered over everything, her latex body so impossibly vast that it extended to the very highest point in the Mesosphere, its rumbling squeaks heard across the continent and its form seen from far beyond even that. The pachycephalosaurus knew none of this, however - she was in total bliss, her body just about to completely let loose.

“Haaaaaah… AAAA! AAAAAAAAH!” And with that, she grew. Grew far faster than even the Alpha raptor had grown. One moment, she was down below the Alpha’s impossibly, unimaginable vast talons. The next, she was up to her knees - then her hip. Within a second, her growth had slammed the top of her previously hard rubber head into the underside of the Alpha’s jaw, the impact so hard that the rapidly shrinking dinosaur was blown off her feet, before the pachycephalosaurus’ growth carried her right on past that thirty mile height, huffing and puffing, panting needily as mile upon mile of size was forced into her body, the squeaking sound rolling like thunder over the continent.

Forty miles. Fifty. Seventy. As her rampant, berserk inflation continued, forcing her body to ascend to maddeningly gigantic heights, the hard-headed dino shifted her feet about to maintain her footing, one toe accidentally smothering the duo of raptors and the parasaur, pushing down on them, hard! A hundred miles came and went almost unnoticed, before a tingling sensation ripped its way through her body, and she BURST up to one hundred and fifty miles in a single furious spurt of size, before letting out a roar that seemed to cause the far-off Sun to wobble in place as she rocketed up another fifty miles, on the spot! Her other foot rose and fell, slamming down on the Alpha raptor and pinning her underfoot once more, the contact resulting in a series of deafeningly loud squeaks.

Finally, the godlike pachycephalosaurus stopped growing, looming comfortably over literally everything in sight, her presence utterly dominating the sky the entire hemisphere over, thousands upon thousands upon thousands of teeny-tiny dinosaurs, invisible to her eyes, gawping in utter shock as a living goddess made of infinitely stretchy rubber took up the entire sky, so impossibly vast that she had literally outgrown the field of vision of many of the normal dinosaurs down below. She wagged her tail happily, displacing dozens of forests’ worth of air with even that simple motion.

Her victory was to be short lived, however. Within seconds of her adjusting to being the single largest thing around, the Alpha raptor had started to grow again, closely followed by the parasaur and the duo of smaller Beta raptors. In one titanic spurt of size, the sheer ferocity of it astounding even the sky-filling Pachycephalosaur, all of them blew up, and up, and up, and up, matching her in seconds, stumbling about as they shook off the dizziness from such ludicrously fast growth. There was a sort of silence for a few seconds as the titans all started at each other, the three raptors sizing up their prey once more - would it be possible for them to take them down without them growing even larger? Far-off dinos down at the very tips of their claws wondered in awe at the gigantic masses of rubber that utterly consumed the earth and the sky with their shiny bulk.

Then, the melee began anew. The parasaur was immediately bowled over by the colossal Alpha raptor, their bodies flattening mile after mile after mile of land as they fell, inflatable bulk harmlessly pinning millions of life-forms to the ground. The Alpha clamped her jaws down on the parasaurolophus throat, the light brown latex squeaking hideously in protest as she did so, biting down as hard as she possibly could, her soft, rounded teeth doing no damage whatsoever to her prey’s light brown hide. Straddling her prey’s sturdy body as she bit down, the raptor attempted to put her rubber claws to use, only to have them bounce off of that brown latex. She snorted in frustration - why couldn’t she have grown large enough to simply smother her out?! She needed to be bigger, and much, much stronger!

The parasaur felt a trembling start up deep inside her body, but she ignored it and the feelings of glee it brought. Being on her back was a position that was almost alien to her, and she rolled over, trapping the raptor underneath her sturdy inflatable bulk. Her front feet stamped down on the raptor again and again, glancing off of her latex skin in the same way her talons had glanced off of the parasaur’s. The raptor grinned ferally as her entire body began to tingle ferociously, unable to stop herself from quietly mumbling - “Need… get bigger…”

The pachycephalosaur had faced off against the two Beta raptors that had forced her off of the cliff what had to be mere minutes ago. Her domed skull had retained some of its hardness from when it was made of bone as opposed to dusty-brown rubber, and she put it to good use, ramming both raptors in quick succession and sending them sprawling, before straddling one and impotently scratching at its chest with her claws. The remaining raptor, however, launched itself at her and sent her sprawling, talons and claws lashing out, only to bounce weakly off of the surface of her brown rubber hide.

The rumbling inside all of the dinos grew and grew, shaking the earth itself in ways that even the titans’ fights couldn’t. Their coming growth spurts were charged up by their frequent attacks on one another - charged up, and up, and up…

If their previous growth spurts were like explosions, then this final spurt was like a nuclear explosion. They roared out their bliss as they grew, squeaking walls of rubber flooding over everything in sight; a resounding chorus of “BBBBI-III-IIGGG-GEEERRRR-HRRRR-RRRR-RRR,” that shook the firmament, the planet wobbling in space as it was steadily outgrown by five gigantic inflatable dinosaurs. Tongues flopped out; breaths came in needy pants and huffs and puffs that stirred the shrinking atmosphere; every available inch of land was overtaken by a tidal wave of growing, swelling, expanding latex skin that groaned and squealed with every tingling surge of size. The continent was overtaken as the multi-hundred mile high mass of rubber grew into the waters, reaching other continents within mere moments, so fast was the berserk and uncontrollable growth.

Soon, they floated in the cold void of space, invulnerable and invincible latex bodies completely unharmed as they formed a ring of inflatable dinosaur around the blue-green, beach-ball sized planet they all just barely outsized, the three raptors arrayed roughly opposite the pachycephalosaurus and parasaurolophus. The Alpha was just about larger than the two Betas, and she growled lowly as she ruffled her latex feathers.

The parasaur glanced down at the Earth, gulping. She knew that she and all of the other inflatable dinosaurs had to be locking out any view of space whatsoever with their squeaking, squealing bulk. They were goddesses by virtue of size.

“Truce?” She smiled bashfully as she spoke, seeing clouds down below battered into nothingness by the sheer kinetic force of her words. The Alpha raptor tilted her reptilian muzzle to the side, mulling over the offer. She wanted to be bigger - and bigger, and bigger, and bigger, growing until she filled up any and all space she could ever find - but if the parasaurolophus was unwilling to fight her, she would only cause her opponent to grow without growing herself.

She growled, scowling as she looked down at the tiny planet before looking back up to the brown-coloured dinosaurs opposite her.

“...Truce,” the Alpha raptor grunted out, impossibly-thick rubber hide squeaking with every tiny motion she made. “Truce.”
