The Planet at the Back of Her Shorts
B_25 & Ploverlvr

I already had the cave set and closed for my workout and, as I prepared to start my session for the day, I realized that I didn't want to exercise alone. I wasn't like the other dragons to workout in public—or even with someone.

I liked doing my own thing. Although I would have wanted to do my own thing with, or to, someone else. I stopped before the mirror set up on the cave wall and checked out my reflection. The loose tank top that curved over my chest and the tight shorts set at my waist.

I couldn't help but grin and twist about. Checking out my ass in the reflection. I never really got to use it on anyone. Passing by the dragon lands, I could feel the gazes and the stares, the few that struggled to make a comment.

But that wasn't what I was into at all. Being able to command attention, to send others into a daze, all that of that, was great and all. But I wanted to do more with what I had back there. Out of nowhere, a thought from Twilight peeked into my mind, and I glanced over at the Bloodstone Sceptre left hanging at the wall.

"I went looking into the magical capabilities of your sceptre to find it capable of summoning different kinds of creatures from worlds far beyond our own!" Twilight had said in one great breath, too excited to remember how to breathe. "They could come at various sizes to countless types! You should experiment, when the time comes, to make a greater contact beyond ourselves."

I chuckled to myself as I walked over to the sceptre and, taking it into my claw, passing it from one to another as I turned around, walking to the center of the room. Looks like I'll be fulfilling your wish, Twilight Sparkle. Maybe... just not in the way you were hoping. Or even expecting.

I raised the sceptre into the air and swirled it around, a red current forming in the air as it channelled with my wish. To not have a creature, but rather, a whole planet dedicated to taking in my ass. Where the whole shape of their home could not compete.

I almost didn't know once the spell had finished as, once the red sea of particles had vanished, there was nothing in its wake. That was until something floated down. Small and blue and hovering before my muzzle. I glared into the pea, seeing, beneath a white mist of clouds, there, on the lands, buildings and specks and the like.

And my smile grew on its own.

My name was Dan and, every Tuesday afternoon, I would sneak onto the roof of my work to catch a smoke. It helped to be as close to the sky as possible as the feeling allowed me to breathe cool air and feel human again.

And today was to be no different.

Or so I thought.

I don't know when or how it happened, when the world went dark for a moment, rocked about, enough to cause a swirling in my stomach. The next thing I knew, the clouds above, thick and vast, were blown away by a single breath.

And my eyes couldn't comprehend the view.

In the realm beyond the sky, where space and its infinity were supposed to be contained, there loomed the massive snout of a dragon. Longer than any bridge as it sprawled backward into the face of a beast. It was slender, blue and cute, with eyes narrowed in a way that suggested nothing good.

"Well," then its voice blew the gales onto the planet, a force that contained the vibrations of her words, as buildings rocked, trees snapped, and roads cracked. "What do we have here? I can't even see you guys." She chuckled. "Not even if I bring my eye close like this."

I scampered back and fell on my rear in seeing that galaxy of a face starting to turn, the entry of its eye, coming closer to us, with a sound, a tearing force, that drew a cry from us. Her eyes loomed vaster than the moon, brighter too, as it shone down upon us.

"But I suppose seeing my workout buddies up close doesn't matter too much." Her chuckling was like bombs raining across the city, an explosion, throughout, as dirt exploded out from the ground, and chunks came out from the roads. "Hope you guys don't mind. But I needed some new, ahem, partners to help me work out."

None of us knew what the giantess was even talking about, but at the same time, none of us were able to question her. Soon the dragon took off into the distance and, all around us, was the immensity of a cave. Those curved rocks, now the walls of what used to be black space, that we could see beyond the sky of our world.

The giantess walked off and, those near the top of the planet, we're able to see her leave. How she turned and revealed the plumpness that was at the back of her shorts. They were polyester, stretched to the curve of her cheeks, defining their shape, and how supple they were on the eye.

The dragon stopped in the distance and started to stretch, ensuring she stuck out her bottom as she raised her arms, coming to look over her shoulder, afterward, in an effort to clock the glazes of an entire planet.

Her eyes tossed to her own butt. "I see there's something you little ones like."

The dragon took a hand and came to slap her ass, allowing the twins to leap within those shorts, bouncing off each other, before settling with a couple of jiggles back into place. Despite being a dragon, she had a bubble butt, easily able to bounce, rock, at the slightest influence.

"What's that? All you little guys want to get back there with me?" Ember pressed a claw to her chin, while the other, started to lower to the back of her pants. She tugged out the waistband, revealing the top of her clanks, the cream coating of blue, and the smoothness that curved out of view. "Can't say I'm opposed to the idea of that. Knowing my butt is having its way, that it's bigger than a planet to all of you minuscule creatures,... it's quite a turn on."

As the dragon thought, she swung her hips, letting us see the cheeks brush into each other, one condensing as the other expanded, then changing as her rump swung back. Finally, she turned back, with lifted arms.

"Guess there's no choice but to put your whole planet back there!" Ember strolled back to us and, as she did so, her every step, was enough to create a slap throughout the pacific ocean. There was something odd, though. "Hey now! I can hear all the tiny cries coming from your planet. Relax now."

The dragon's claws glided beneath our floating earth, cradling it, as her other stroked the top of our clouds. She then whispered with gales that circled our globe. "I'm sure your kind has already realized that, if I wanted you destroyed, it would have already happened by now."

It was true. She could wipe us out of existence with her breath alone. Which caused me to wonder why it already hadn't. "Destroyed gym pals aren't great at seeing my greatness at play. When I summoned your planet, I did so with a spell, that protects it from all the little things I might do, and not realize, are very big for you."

The dragon smiled. "The name's Ember, by the way, and when all of you go into the back of my shorts, you'll be perfectly safe!" She then stepped back and bent forward, allowing the planets that were her breasts to hang in the distance, a canyon beyond her tank top, of which, we could hangover like a necklace if she so chooses. "But I think we've wasted enough time introducing each other."

She smiled at her palm, which, even though being far below our planet, caused us to glide with it. Ember brought us to her back, well above her shorts, which loomed visits beneath us. High in space itself, the titan of the dragon looked at us, down from over her shoulder.

"It's about time we got squatting, shaking, dancing, and everything!"

I wasn't sure how to feel, in looking to the sky, to see how my whole surroundings were actually being plunged downward. That sprawling waistband, clung to her waist, seeing the entry of her monolithic claw. Those pillars of talons, digging in beneath the band, slowly, teasing their way inside.

There was something about Ember's ass, as it was now, that drove insanity inside of me. How the fabric rolled over the top of her hills, accentuating them, thickening them with its material, causing a throbbing from me to come below.

And then the talons peeled the band from the ways, and pulled the sea of polyester from over the creamy hills, revealing the extent of the cavernous booty that was beneath us. Ember looked at us with glee with all that she was about to do.

Putting a planet, plunging billions, to become nice and snuggled with her butt. To know that we were trapped at the back of her shorts, helpless between something like her cheeks, as she worked out, and let them be free, to either our torture or pleasure.

Slowly we sunk down the back of the dragon before seeing the stretched-out band across from us, the light around us, going dark, the lower we went. Soon the tops of the cheeks were directly beneath us, sprawling in such a way that we could not see its end.

Somehow it was soft. Despite the scales, the mass beneath, was soft, compact, with a touch of squish to the thing. The hand-pulled away for a moment, with the back of the shorts, still held, as Ember glared at us.

"Hmm." Ember hummed. "Can't say that I like having all of you up there."

I gulped as the claw then dragged us backward, where the hills started to dip in their slope, and we went along for the ride, to the back of the shorts. Snug between the arching wall of the fabric, and the curve of the flanks before us.

And that's without mentioning the titanic divide between the cheeks before us. Our pea of a planet floated before that massive crack, teased to how its softness sliced inward, where absolute tightness blocked further view.

What would happen if she had left us back there? If her claws had pushed aside the immense weight of her cheeks, left us deep in that canyon—and let the monolithic twins close on us? Nothing but warm, smooth, grinding darkness, as the dragon did as she pleased.

Maybe, even despite our place, we got lucky in that regard.

Once the claw had set us in place, we watched as it trailed back, in the abyss that was the back of the shorts, seeing how it snaked over the flanks, to where the opening of heaven loomed. Once the talons sunk out from the shorts, the ones holding them back, started to release the band, slowly, returning it to Ember's hips.

The light, fading from us, with every inch it closed.

Until the thickness of the band snapped, lightly, into her back, sealing us, not in darkness, but rather, dimness. This dragon had placed us into the back of her shorts, forced to hover just before her cheeks. With nothing but the wall of polyester sloped behind us.

And then her voice rang from the great beyond.

"Looks like everyone and everything is set!" Ember laughed. "Let's get on with it then!"

I couldn't help but swing around, checking myself out in the mirror, the way I made those shorts pump out. There was the tease of the planet, nothing more than a little bulge, barely seen between my rolling hills.

I couldn't help myself. Slapping my behind, I watched as it jumped and wobbled, smushing over the planet before falling away. My tail hovered out of the way. I wondered how that must have looked to them.

But then I returned to my mat and, getting ready, began my workout.

It was an impossible sight that flanked on either side, beyond the sky that had once been blue, which now revealed the galaxy of the interior of those shorts. To our sides were the rolling cheeks, plump and blue and thick, arching into a dimension that was beyond our comprehension.

And then something rumbled from the beyond. I ran over the grey coating of the roof of the building to peer over its railing. Down on the streets, people were running, dashing as though they could escape the fate that was around us.

The twin and curved planets closed in on us, the softness within the cheeks, compressing, as they compacted and hurtled toward us. I thought that was to be the end as I watched the inside of the flanks, their sides, bounding toward us.

To have a planet be crushed by immense softness... whoever would have thought it?

But as the cheeks closed in, the twin walls of scales, rubbing and bunching on each other, the same, however, did not happen around us. The flexible plushness smushed around our planet, cupping it at its sides, as landmarks came to crumble not from the material, but rather the winds, the power backed behind the momentum of such colossal things.

And then, even for a second, everything stood still. We were buried in the ass. Nothing but the pushed-together cheeks of a dragon's butt as, in a place beyond any modes of transportation, her claws were holding her buns together.

How did that look? To be holding her ass together, to accentuate the plushness of their shape, while looking back, admiring their form through her shorts? Knowing we were now stuffed inside, resting on the precipice of the cleft, as though teasing the deeper, darker, and more damming domain.

It seemed as though a shield formed over our planet, that not so much held the cheeks back, but rather, caused it to flatten around us. Few seconds passed like this, before the twins fell away, a bounce that echoed through heaven, creating a Milkyway of energy in the back of her shorts.

Which seemed to be the start of her first game.

"I hope all of you little ones are enjoying yourselves down there!" came the tease of the giantess as, from the thunderous cracks of her steps, she seemed to be readying herself for something. "Hope you aren't getting to anything that I wouldn't like. I put you back there to help workout."

There was no way, even if my shouts from this building could reach this giantess, that we weren't doing so.

Those on the streets that had given up on the fact that they couldn't be saved, instead, laid back on the ground, pants down, with hands in places not usually found in public. There was not discrimination either.

Ember must have sprayed perfume, or maybe it was the natural odour of her body, for the scent of her booty was as sweet as lavender. Husky and rich and a little burning on the lungs with its heat. It drove one crazy. The urge to sweat and feeling a longing in a place below the belt.

Most looked on to the titanic ass that surrounded them, as it compressed and spread, how it was always there, always so close to matter how far it jiggled away. Seeing how a little bit of the cheeks would be allowed inside the shield, the smallest amount possible, how it would roll onto the land, crushing empty apartments, flattening great parks, leaving the imprints of individual scales.

Everyone enjoyed the effect of being toyed by such a massive butt. How it controlled the world with nothing but the smallest fraction of its essence. How it's distant wobbles were enough to create pleasant earthquakes.

"Now, if the billions of you are ready, we're going to start off with the first part of this exercise," Ember said as, faraway, her legs started to spread. The chasm of her cleft began to widen, and our dismal planet floated into the opening. Entering the crevice as the inside of those cheeks loomed to our sides. "Which are squats! Now, I know it's hard to get your form right, and we really only do squats for one reason."

There was laughter that caused a wobbling to those flanks. They even rubbed into the fabric of the pants, which flexed to their bounces, those vistas of sewn material, straining to hold the pair. "So I've put all of you close enough to see how it should look when you do them right. Just, hehe, try not to get sucked in, okay?"

None of us were sure how to feel about that, that was, until our world started to drop. It was almost like our gravitational pull was centred on the massive ass that was before us, certainly big and wide and warm enough, of course, to replace our sun.

But that ass backed in shorts started to drop, and so did we, as the crack that divided the cheeks started to gradually widen. We floated deeper inside, as though it were a lazy river, entering further than we ever should.

Soon the structure of the dragon paused as we were halfway inside the butt, where the cheeks were at their thickest, softest, and most compressed. They were spread to the sides as the dragon was now in her squat, holding it for a second, with a planet wedge a little into her rear.

"And squeeze!"

My head whipped from side to side in seeing the closing of the plushy mountains, swallowing an infinity of space that was the chasm between us, the massiveness gaining on us. Within a moment, we were buried once more, with plentiful butt stacking into our pitiful planet.

It was strange to be inside a girl's ass as it was clenching. To see how it pressed into our planet, slowly, with tons and tons of fat, toned fat, stacking behind it. Mounting and amounting to a quantity without a number.

I looked behind, over the city to the horizon, beyond that to the space of the shorts. Far in the distance was the entrance of the valley, a long, thick line, that was closing up. Thinning and dimming the lights. Until the crack, closed, and there was nothing more.

We kept in darkness and stillness to the sounds of the butt rubbing into itself. Unsure if the ass would cause us to pop from the insurmountable pressure it applied onto us. We couldn't tell the walls from the ceiling as both were composed of the same squish.

We waited and waited until, finally, the walls started to peel from each other.

Slowly, our planet drifted out from the crack, on its offset, as the titan stood up.

Her ass hung above us for a moment, letting us see it in all its glory, that was, until it dived into us. It's maw, opening, and taking us into its cleft. Then the valley of scales sealed, the softness, piling once more, as a huff came from afar.

"Mhmm..." Ember's voice echoed. "Hehe. Having all of you little ones back there is making this easier." She went to stand, except this time, kept us buried inside of her. We were nestled deep inside her butt as she stood. "Helps me to know the center of back there. Once I know you've floated into that special spot, that I've met my mark."

She then squatted once more, allowing the planet to float out, as her butt hung on the horizon. She kept this on for a few more times, taking us inside, squeezing a little, then letting us float out as she stood up.

Soon her squats were over.

I couldn't help but feel giddy as I felt their planet float deeper inside of me. Not too deep as to get sucked in. But wedge just enough to be dwarfed all around. I came to let them stick between my flanks as I stood tall, with my claws, together, resting behind me.

I'm not sure if you're all terrified or feeling extremely lucky.

"Hope all of you are enjoying your breather! Just look at how toned you're making me!" I giggled at the joke and gave another slap to my ass. I could feel how the twins rocked, beating into that little planet, forcing it left and right, through the force of those wobbles alone. "But the next step is cardio! Hope all you little ones are ready!"

I could see it in my eyes. The spread of panic across the world. From country to nation to state to town to home. All those little ones, no matter where they lived, seeing nothing but me around. To know they were trapped inside the darkness of my shorts, forced to room with the plushness of my butt, unsure of when it would break through that shield—just how much of my ass they would be able to take.

I could see all the naughty people too. Down on the streets, unable to get enough of me, regardless of what they see. Maybe they would mate with each other. Driven to insanity by my booty to the point that they were having each other as my cheeks clapped upon their homes.

I liked the idea of that a lot.

That's why, in clenching my butt to see the planet tucked between my cheeks, I shifted, a little, to roll it more to the center of the twins. Feeling it tight and secure, I loosened myself, enough that I wasn't gripping the planet.

And then I started to jog in place.

I was worried when the titanic booms came like continuous thunder in the air, seeing how the cheeks would launch away, as they would fall back a second later, a heavy clap, that deafened us all. Light to darkness. Looseness to tightness. Seeing how the sides of those scaly marshmallows rose and dropping as they were jostled in place.

I looked out from the railing to the waters that surrounded my island. Seeing how, in the masses that jostled around us, the throwing and the crashing of the sea. Tidal waves, self-contained, rocking about the vistas of water.

And even those weren't even a droplet of water compared to the jumping immensities. Even I couldn't help but fall back, feeling a growing below, one that I supplied a hand to help satisfy. Knowing that this scaly giantess would rock the oceans of the world with her butt alone.

It wasn't even the weight of her ass, or the bouncing of cheeks, but rather, how their force rocked through the air. Their momentum carried outward, even still, enough to create a storm in the sea. Magic must have prevented the breaking of the ocean from reaching us.

Rather the seas became like a bathtub, with the waters splashing freely, that never splashed outside the tub. Her feet echoed below as they smacked into the ground. The wagging of her tail, creating winds able to set solar-systems off course, reminding us of where we were.

Ember was running in place, no doubt raising her legs high, enough to thoroughly grind her cheeks into each other. Rubbing softly and tightly and allowing us to see how the scaly walls flexed in that regard. In every iteration, we were slid outside, slowly, in our freedom from her booty.

But even as we floated out from the massive ass, spat out like candy no longer enjoyed, we were still forced to watch, from all aspects of the world, to the activity of Ember's posterior.

"Do all of you like that? Being in the back of the shorts of a dragon, that is?" Ember's voice spoke to us, through a couple of huffs, as she went on telling. "Y'know. It's a bit of a power trip. Knowing all of you are back there. Nothing more than a treat for my cushy behind."

Her following chuckles, well humorous, weren't endearing to us. "I've never told anyone that I'm proud of my ass. Not many you meet where butts become the subject." We were forced to watch a cheek rise, compressing and becoming larger as it did so, before dropping, with a booming bounce, as its twin did the same. "But it wasn't good enough to toy some dragon with it. The stares are nice—but nothing close to what I desire."

What did this dragon desire from us? We watched her ass jog before us, on a scale beyond our understanding of a galaxy, where only a fragment of her booty touched upon us. Were this more primitive times, we would have worshipped such a thing, as either a religion or as a goddess.

Or maybe we still would.

"What I craved was to have a whole world, not enslaved to it, but definitely enthralled by it." Ember hummed as shadows were coming through the back of the shorts. Those on the street looked back, through the wormholes that allowed light to shine through the shorts, allowing us to see, to an unimaginable scale, the blue claws hovering there. "I wanted it to be more than anyone could take on. Or even touch at all."

Those close floated in, and suddenly, the world inside the shorts, changed, as the claws started to cup the plushness of the cheeks. Cupping them so as for her talons to run across the natural slope of their underside. Then she raised them, bunching the sisters, enough to pronounce their shape further.

"Do you know that it's my butt that's protecting you from the world at large?" Ember slowed down in her jogging, as her claws fell away, allowing her derriere to take its natural shape. "Think about what would happen if I took you out from my shorts! So many large unknowns. Other unkind dragons."

Little giggles. "Even the wind could take you at this point."

The next batch, however, were softer. “But this thing.” Ember twisted her hips, shaking her ass, making it jiggle as she twerked it. "It's big and soft and able to protect you. It's a pretty good deal—that is... once you get over the humiliation."

That was true.

Although those on the street that was pleasuring themselves to being degraded to the back of a pair of shorts, with an ass that no rocket could ever fully explore surrounding us, others would find it harder, more difficult to return to their normal lives, with the rolling hills of a scaly bottom always lurked in the beyond.

Is that how life would be? Picnics outside in a park, eating while looking up the clouds, with the rolling ass looming just beyond that. Knowing that, when you're going to sleep, that your whole world is flanked by two massive flanks?

That it cupped and housed the world. That we would be shaking and brought along with it. It would become our everything, eventually, as it already was right now. It meant that we were safe. And most might find more pleasure in their days.

"...I can hear you thinking about me."

I blinked and coughed as I looked out to the ass on the horizon. The starting of the underside of cheeks as their curve went far beyond my perception. Did she hear my thinking? Or someone else, someone more important in the world? Or our thinking, figuratively speaking, as a collective whole?

"Just you."

I swallowed and fell onto my own rump at being called out.

"Don't forget how all of this is going to be from my perspective as well," the humour in Ember's voice quaked around us, expressing the crashing in the ocean, the falling of streets, and the vibrations in the streets below. "Knowing that, when I walk, there's a planet witnessing the shifting of my cheeks."

I shook my head and felt myself throb harder. Tightening my grip, I started to pump harder, faster, while still at a steady pace. I looked out to the massive butt and, even though it was something I would never touch, feel, or get to cup or experience—the mere fact of its size, of its existence, and its effect over us was more than enough to push me over the edge.

"Not to mention how differently the days are going to feel with all of you back there." Ember must have known of my actions as well as, at that moment, her hips began to swing, from right to left, entering into a bit of a dance. "Knowing that, when other dragons are checking out my butt, that they have no clue that a planet is back there."

She laughed. "Maybe they would even be jealous of that."

I watched as one cheek flexed to the left, with the other smashing into it, following the girl's dance moves. She was doing it slowly, being sure to spread herself out, knowing how to cast an effect on us. I pumped a little activity in watching the cheeks move, at that cleft, opening and closing, teasing us to its delicious confines.

"It'll be harder talking to friends when I know there's a world calling out from the back of my pants," Ember teased. "That, when I sit down, either you'll have to float above my pair—or be sandwiched by them for the course of a meeting."

That was enough to get me going as the dragon started to dance in place, stepping from foot to foot, ensuring to raise her arms, one holding the other, and flexing out her butt. How those massive twins loomed before us. So gigantic and monstrous while being plump and firm.

"Maybe I should give you a closer look to exactly where you could be staying."

Her claws then dropped as she leaned forward, shoving out her ass and grabbing its sides, holding flanks apart as to widen the chasm before us. How it opened up to an infinity of space between those cheeks.

"Tucked between the two and kept safe at all times." Ember chuckled. "Maybe I could find other places to keep your kind. Though if you think my rump bounced around a lot—you might not make it with my other rack."

Ember decided to let her cheeks close, the massiveness, started to close, a portion of the cheeks, breaking through the shield. Suddenly, a portion of people were teleported to the tops and bottom of the planet as, at the sides, I watched as the cheeks closed in.

At first, they were covered in mist, blurry and hazy due to their size. However, little of a portion was able to loom beyond the fog. But like a gigantic spaceship, it closed into the earth, a new ceiling to our world.

The titanic cheeks then settled onto the water, monstrous waves splashing from the touchdown, not even the depth of the ocean able to house the never-ending plane of the cheek. Everything else was crushed in its wake.

With its terrible sound of its passing, the immensity of the cheek rolled onto the beaches, flattening the sand, leaving islands of scales from its imprints. Forests crunched and were no more as the softness of the cheek came to rest on its place.

Next were towns and cities, now possessing no life, that was swallowed in the shadow of the flank. Buildings crumbling at the slightest touch. Floors caving from the coming winds of the movement. Within a second, the cheek laid over the area, swallowing it beneath its mass.

Then, as the cheek rested over the zone, it started to rub, slowly, every mile of its activity, unable to be tracked, as there was simply too much even in its simplicity. Once the butt had rubbed into the towns beneath it, the ass then peeled away, remnants of structures, raining and pelting from it, as that section of the cheek returned the galaxy that was the interior of her shorts.

"See what I mean? I don't think your puny planet can handle any inch of me." She then hummed. "Also, don't worry. The magic I've cast will reverse any destruction I caused as well as hold up the increased number of you. But, before that..."

Ember then gave a slap to her ass, at the same time that I finished, to the mere resting of her butt that was forever in the background of our world. The next thing was how her cheeks shook, from the slap of her ass, as the girl started to walk, the twins, grinding into each other before she plopped onto her front into bed.

"But I think it's time I took my afternoon nap."

She then patted her ass, her shorts, as though to tuck us deeper into her.

"Think I'll leave you guys in there... not that you... hehe... mind.”
