Unmeasurable Ass
You were quite surprised at this turn of events today. Your fashion-obsessed unicorn friend Rarity dragged you to her home and wanted you to examine her rump. She used her blue-coloured magic to grab you by your coat and take you to her house. You could do nothing to stop the unicorn mare as you just let yourself be dragged. Leaving skid marks on the ground from your shoes as you got dragged.
The mare wore a red dress over her snowy white rump, giving a stark contrast to her backside as it reached the beautiful sequin-covered red dress. You had a massive eyeful of her rump from your position as you were forced to stare at the beauty of it. Her dress only covered about half of her rump, leaving the underside of her cheeks fully exposed for you to admire. The cheeks leaked out the bottom of her dress, jiggling and shaking like marshmallows in front of your eyes.
Rarity's buttcheeks were completely smooth and round despite their substantial size. Clearly, there was some pony magic, as no rump could naturally be that big and jiggly while being soft. They were practically like extra large pumpkins in your hands. Your hands were sunken deeply into the white marshmallowy softness of her fat rear. Her ass put any human woman's ass to shame, it was meaty and perfectly round and smooth.
You didn't expect Rarity of all ponies to want you to manhandle her rump. You were down on your knees as you held your hands firmly against her plump cheeks. The fat of her backside sank around your hands like you were holding a marshmallow. You were left a blushing mess as you ran your hands along her butt.
Deep beneath the thick layers of bubbly fat, you met her iron-clad muscles. Rarity, like all ponies, was quite shorter than you, but that didn't really matter since her ass put any human woman to shame. The four-foot-tall mare may be short, but she sure was stacking. Her rump jiggled and bounced around wildly, even with the slightest move, like a tree in a heavy wind.
Maybe you were imagining things, but Rarity also seemed to become much bigger. Honestly, her ass seemed to become larger than ever before. You were left thinking to yourself as you enjoyed the view of the swaying rump in front of you. Your cock throbbing in response to seeing this lewd display in front of you. The cock of yours throbbing and dripping pre in your pants as you kissed her rump. The taste and smell of marshmallows hitting your nostrils and flowing up into your brain like water.
Her marehood was winking at you excitingly as you held your hands firmly upon her rear. Succulent whipped flavoured love cream was leaking out of her twitching marehood. You know so since you could smell the scent of her sex. The sight of her leaking sex prompted you to deliver a quick swipe of your tongue over her sex. Rarity moaned at the feeling and promptly bumped her rump against your face; she clearly wanted more.
Experimentally, you pulled your right hand back and watched as the fat of her ass returned to a perfectly smooth shape like a still lake. It was like a pillow as it slowly formed back into place after only several moments of your hand being absent before pressing your hand back down upon her rear, watching in delight as it sank into the plushy, bubbly fat. The fat was like malleable dough under your hands. Moving around so easily with your hands as you made circles on her butt.
"Mmm, yes, darling, I love that, but please focus on the task at hoof," she said sternly, shaking her head at you. "Please use the measuring tape," she said, signalling for you to use the measuring tape levitating above her rump by flashing it with her light blue magic. Her horn glowing and sparkling with the light hum of her magic filling the air.
The light blue magic flowed up the groves in her horn like a waterfall in backwards motion. Eventually, reaching the top before the spell, you reached out and grabbed the measuring tape. The metal measuring tape glinted in the sunlight coming from the windows in the boutique. You gulped and nodded as you reluctantly took your hands off her ass.
You did what you were told and grasped the measuring tape with your right hand. Pulling on the clip on the end of the tape measure and unleashing the yellow tape within. Various numbers denoting inches and feet are on the measuring tape. You placed it upon her rump to measure it. You focused your eyes and looked at the end of the line of the tape.
It seemed to be about 40 inches, about as wide as an extra-large television. Your eyes went wide as you imagined what you could do with this much rump. Practically salivating at the thoughts before coming back to reality, blushing as red as a tomato as you continued to measure her legs before stopping.
But then you began to notice something rather peculiar beginning to happen. It seemed you had not pulled enough tape; you must have pulled a few inches short of tape. You pulled a few inches more and examined the width of her rump… only to find you were somehow a few inches short again. You tilted your head in confusion and scratched your head. Putting the measuring tape in front of your eyes and inspecting it, trying to see if there was some sort of special magic on it or something. Though you didn't find anything wrong with it. What could be causing it, though? You thought to yourself with a sigh and shake of your head.
"Come, darling, how big of a dress will I need?" she said in a rather impatient voice. Tapping a hoof against the floor, which makes her whole butt jiggle and shake in front of you, filling the room with the sound of her clapping cheeks as she does so. The slight bit of fat on her thighs jiggled as well with each slight bounce of her hoof. All you could see in front of you was the white hills of her marshmallow rump. Making it so you could barely focus, but you managed to pull yourself together to continue working on measuring.
With nothing else for it, you decided to pull about 10 inches of tape out and placed it upon her rear, only to be spontaneously met with an emergency car airbag of fat, snowy white rump pushing against your face. Her ass jiggled and bounced the sudden flood of fat pumping into her rump, her clapping cheeks creating a loud, meaty slapping sound. Her rump was like a snow-covered hill in winter in the middle of a blizzard. Leaving you slack-jawed as you looked down at the measuring tape, a bit annoyed.
Rarity's dress had slid up now and looked painfully tight above her rear. Her dress was like it was painted on her rump at this point due to how fat her butt was. You could hear the dress creaking and groaning like the stressed hull of a ship in a storm, some of the sequins popping off and going flying through the room at high speed. It was straining against the gargantuan bubbly cheeks of Rarity's ass.
"Oh, darling, I feel strange. But anyway, try to get my measurements," Rarity blushed deeply and looked back at you, staring at you while she tried to see why she was feeling strange. Though she doesn't really see anything wrong just yet so, she goes back to looking forward, humming quietly to herself as she waits for you to continue measuring. Though you were fighting a losing battle at this point. Trying to stop her from growing by holding her butt with your hands while measuring it. Your hands sank deeply into the plush fat of her rear while doing so.
You gulped, forcing the tape back upon her rump. Feeling it sink into her backside like it was quicksand. Your hands struggle to even pull the measuring tape enough to cover her rump. You grunted and groaned as you struggled to measure her rump. Her rump has now become so large, straining your arms just to even wrap it around the great snowy hill mass of her cheeks.
Your muscles are straining in your body as you did your best for the mare in front of you. There soon came a dramatic tearing sound as the dress began to tear apart as Rarity's rump ballooned further in size. The rest of the sequins flew around the air and filled the room with thunking shrapnel. Not doing any damage to anything but making a massive mess.
Rarity turned around and looked upon her ruined dress. The butt of hers had exploded out of the dress and made a huge tear form in it which made it look like the crevice of a great ocean trench. Upon the sight of her ruined dress, tears came falling down her cheeks. "My dress, my fabulous dress. Oh, this is the worst possible thing! And I've become so… so… so…I-I," she stammered her words, unable to speak further. The look of sheer shock on her face made her seem even more pristine white than usual.
"What is it, Rarity?" you asked gently, laying your right upon her fat, bubbly cheek. Your hand subsequently sank into the marshmallowy softness of her plump rump, creating a deep depression into the smooth fat of her rear.
"Fat!" Rarity wailed, dramatically bringing over her Drama Couch with her magic before dropping herself down upon it with a loud bang. The couch creaked loudly from the heavy impact of her rump slamming upon it. Her butt jiggling and shaking violently from the sheer force. A massive shockwave from her rump cheeks clapping together, knocking you over. You shook your head and eventually got back to the mare. Running over to her and trying to comfort her as best you can.
With her magic, you could see the mare bringing over a very large cookie-cream-flavoured white bucket of ice cream. She brought the ice cream near her face and levitated it in place, holding it with ease as if she had practised this for a while. You could see the indents from Rarity sitting on the Drama Couch. You tried your best to run your hands through her mane, doing your best to soothe the marshmallow mare.
The mare gave you a warm smile before beginning to devour the ice cream while she wailed in grief. She ate the ice cream with a very large silver spoon she held in her magic. The massive spoon grabbed massive golf ball-sized ice cream and scooped it up before she brought it to her maw before she slowly ate the ice cream, which only made things worse for her.
Rarity cried and moaned in bliss as she consumed the ice cream with ravenous gluttony. You watched the crying mare inhale the ice cream into her maw as you stood there rather awkwardly. The bucket of ice cream appeared to be magical in nature since it seemed to be refilling itself as she ate the ice cream.
While she was consuming the ice cream, you also began to notice that Rarity was slowly inching upwards into the air, and below, you could see her asscheeks were growing bigger and bigger like inflating balloons. The bwomping of her rump was almost deafening as you started to massage her rump. Knowing the mare absolutely loved massages.
You were tempted to try to stop her from eating the ice cream, but seeing that rump of hers get bigger and bigger was causing your cock to become stiff in your pants. The soft hills of the rump rapidly started to cast a bigger and bigger shadow across the room. Leaving you speechless as you slowly started to back up more and more. Being forced farther and farther back to continue rubbing her rump. Trying your best to keep yourself from being crushed by the growing marshmallows in front of you.
As Rarity grew and grew, the Drama Couch below began to creak from the great weight of her ass piling up on top of it; cracks formed on the legs of the couch as it let out loud creaks and groans which were like the wails of a dying animal.
Clearly, the couch wouldn't last very much longer as splinters fly around the air and slide across the floor. Being turned into a shaving-like dust under the rump of the mare. Ultimately, the supports of the couch snapped, and it simply crashed to the floor with a loud bang, sending sharp splinters and chunks of wood flying everywhere. However, they seem to turn to mere dust upon contact with your body. Leaving you completely unharmed under the relentless barrage of the pieces of the couch.
Rarity was still growing over the remains of the couch beneath her hefty ass, slowly crushing whatever was left of it into fine sawdust as the weight continued to pile on. Her butt hitting the floor with loud booms and shaking the whole room. Causing you to almost fall over as the clapping of Rarity's cheeks fills the room. Her buttcheeks have reached the size of her couch for each cheek. The wooden floor underneath began to creak and groan as more and more weight pressed down on it. Fissures started to form on the floor as the structural integrity of the floor started to slowly fall like a dam against a tsunami.
You positioned yourself behind Rarity and watched her rump inflate bigger and bigger like a balloon. Each one of her cheeks was now practically the size of a ten-foot-tall beach ball. Having doubled the size of her couch and left her towering over you from the rump of hers alone. Forcing you to have to crane your neck up as high as you can to look at her. Your muscles strained to maintain this staring as you ached down under. Your cock throbbing in your pants and desperate to punch through them. You roughly estimated Rarity must have grown to at least the size of an African Bush Elephant.
You wanted to manhandle her ass some more and made to reach your hands out to grasp those fattening cheeks, but you stopped when you heard Rarity gasp in shock; this soon came accompanied by a loud bang when the bucket of the ice cream and the spoon dropped to the floor. The bucket rolled along the floor, somehow not spilling any ice cream. Clearly, there was some magic involved to stop the bucket from releasing its contents.
The bucket appeared to have become larger; it was like an oil barrel in terms of size. It had a massive white bunny on the front of the blue bucket, which was wearing a nice suit. You could tell this was a very expensive ice cream due to the labelling. Maybe the magic was in the bucket before this growth still happened, or something else was afoot? You would perhaps never find out. The spoon also became the size of a shovel. The piece of silverware hitting the floor caused a large amount of splintering on the floor from the sheer amount of silver in it. The spoon continued to Sparkle as if it was spotless even though Rarity was eating with it.
"Oh… no. I've become even fatter," the mare said in a low voice, looking back at her massive backside in disbelief. You decided to take decisive action by placing your hands on her soft marshmallowy cheeks; forthwith, you began to stroke her lovely fat cheeks; your hands sinking into the plush bubbly fat of her ass; creating deep depressions into the soft bubbly mass.
You could barely move your hands around on her rump due to how her butt was like a black hole. The butt of hers sucking your hands deeper and deeper, surrounding it with his warmth. "Oooh, darling. How could you love a big fat mare like me?" she asked in a shocked but also hopeful voice. Clearly, she was hoping you still enjoyed the fact you might worship her rump due to how big she had gotten from all the ice cream. Most of the ice cream had gone to create fat on the diamond rump of Rarity.
Your pants became wrapped in a light blue light before they subsequently vanished with a puff. A puff of light blue smoke accompanied the disappearance of your pants. Leaving you completely naked from the waist down as she took your undergarments off you as well.
Your mighty 20-inch cock bobbed up and down from being suddenly unleashed from its prison. The veins throbbed within the fleshy prison they were contained in as they struggled to pump blood into the monster. It was a monster just like that of a horse cock in human shape. Twilight wanted you to fit in if you ever got a mare. She was such a thoughtful mare, after all. Making this all possible for you in the first place. You must find a way to repay her somehow. Of course, she gave you a just friend's blowjob as part of a scientific experiment.
Rarity squeezed her asscheeks together, making a lovely place to slide your cock into. Giving you a massive crevice to force your cock in between. It was like looking into the Marianas Trench from your view due to how big it was. Your balls gurgled and sloshed with gallons of cum which were meant for the mare in front of you.
With that, you brought your cock forward and slid it between the great mass of Rarity's cheeks. Your cock became enveloped in the warm marshmallowy softness of her snowy white cheeks smothering it on both sides like mattresses. Slowly you pressed forward, sliding your cock between the tight gap of her buttcheeks. It was quite an arduous task, but eventually, you managed, and with a loud pop, you forced it in between her cheeks.
Inch by inch, your long cock sank into the abyss of Rarity's cheeks. Until eventually, your tip made contact with her hot marehood deep beneath the great chasm of her buttcheeks. The tip let out a massive drop of golf ball-sized pre as it touched her marehood. You were quite excited at the thought of breeding this generous snowy white mare. You only managed to slip in about 3 inches of your 20-inch cock into her marehood; the gap of her buttcheeks was so significant. The head of your cock forced itself into her but nothing else due to the size of her rump. Figuratively speaking, It was like putting down a ladder from the top of a house's roof to reach the bottom.
Nonetheless, despite the insignificant amount of cock you could give her, you began to roll your hips back and forth, causing Rarity's buttcheeks to bounce and jiggle about as you humped against her. The loud sounds of sex rapidly filled the room and bounced off the walls.
You moaned and panted as you tried to grip Rarity's rump to gain a hold. Though your hands were just shaken off by how much her butt was jiggling. While having sex with her, you also moved your hands over the plush fat of her rear and watched in delight as your hands sank into the plush, marshmallowy softness of her ass. Thus you managed to get a secure foothold on the beach of her ass, making it easier for you to fuck her.
Rarity, for her part, moaned from your loving attention. This prompted the mare to pick the ice cream back up with her magic along with the spoon and begin to consume it once more. Rarity's ass immediately began to inflate like a balloon against you, slowly pushing you backwards as it got bigger and bigger. Your cock soon came slipping out of her marehood and came to be simply sandwiched between her ballooning cheeks.
Rather than be turned off at this new development, the massive snowy mare moaned and promptly began to rock her hips back and forth, which resulted in her grinding her rump against you. Thunderous, meaty clapping sounds could be heard as her fat, bubbly cheeks came slapping together during her movements.
You groaned in mild pain as the heavy rump of Rarity came to repeatedly slam against you. This should hurt a lot more, but perhaps Rarity safeguarded you with her magic. The Carousel Boutique was quickly running out of room as Rarity's ass ballooned ever bigger. Her head bumped against the ceiling, and her head subsequently came crashing through it, shattering it apart in a brilliant display of power.
This was soon followed by you being pressed against the wall behind you with Rarity's rump enveloping your entire world in darkness; you could see nothing but Rarity's ass. Even now, you could feel it ballooning further against you and the wall beginning to crack behind you from the immense weight of her ass.
Despite the clear magical protection, you groaned in pain as the immense weight of Rarity's rump pressed against you. The shield she provided you starting to crack a bit from the increased weight. However, it managed to hold itself together due to the growing magic of Rarity. Allowing you to stay unsquashed for the time being. With magical aid, you could see Rarity giggling as she loomed over you.
The size disparity between you was tremendous as you were surprised Rarity could even feel you at her size. Nearly the entirety of the Carousel Boutique was completely destroyed by her rapid growth. Crushing various marequins and her sewing table. Turning them into mere pieces of destroyed debris meant for the local dump. The only thing that was left was you pressed against the wall with Rarity's ass pinning you against it.
The ponies of Ponyville began to gather and look at the commotion that was taking place. Rarity ignored them and casually released her levitation hold over the spoon, now about the size of a Roman pillar. The spoon continued to shine in the sunlight, which allowed the unspoiled beauty of the mare to be seen. The ponies of Ponyville were left in utter shock as the marshmallow mare towered over them. Subsequently, the spoon came crashing to the ground with a loud bang, as if it was a car being dropped from a crane. Next, Rarity levitated the now water tower-sized ice cream bucket over her gaping maw. She opened her mouth up before lolling out her tongue like a red carpet for a celebrity. The celebrity, in this case, is more of the delicious ice cream.
Rarity completely disregarded being ladylike and simply licked up the ice cream with her tongue. Her growth rate began to skyrocket from directly eating the ice cream out of the bucket; the wall subsequently was destroyed as her rump came rolling over it.
The gathered ponies had no time to react before they were taken under Rarity's ass washing over them like an avalanche of snow. Fortunately, you and the other ponies were somehow not crushed as Rarity's ass smothered you. However, you groaned in great pain as the ass of Rarity bore down on you like super heavy anvils.
Your bones cracked and creeped as the immense weight of her ass pressed down on you. You were immensely thankful that Rarity's magic was holding your body in place despite the great mass of her ass.
The buildings of Ponyville were not so lucky. Rarity's divine mercy did not seem to extend to them. They were only pawns in her ever-growing game of chess. She was going to destroy them as if they were nothing by card houses being blown over by the wind. The slow, inevitable tide of snowy white ass creeping along the ground like vines across a wall. Rarity's cheeks rolled over them as if they were a tsunami, crushing them into nothingness as her great weight pressed down on them. Turning them into nothing but more fuel for her growth. Encouraging the mare to eat even faster so she could grow even bigger.
You could see mares beginning to cry out in anguish for some reason. You then could see with magical aid that Rarity was sucking the fat out of their asses and making their bodies puny and tiny; further and further, they shrank until they might as well be about the size of a house cat, their rumps as flat as pancakes. Leaving them absolutely unattractive to all stallions around.
Rarity was the only mare any of the stallions in the town would ever be attracted to. This was all part of her master plan, of course. All the while, Rarity's ass ballooned on top of them bigger and bigger. Giving all the mares more of a reason to cry as they were left farther and farther behind in the ass department, and they could never hope to catch up to the marshmallow goddess.
"The time has come!" Rarity boomed, her mighty voice echoing across the planet. Shaking buildings and knocking over mountains. Even causing avalanches in some places but leaving no creature harmed as they were stopped from harming creatures by her power. Rarity was an omnipotent goddess at this point. The fabric of reality was like fabric on her sewing table back in the boutique.
Rarity's three diamond-blue cutie marks began to glow with a blinding light; this was followed by a pair of massive feathery wings appearing on her back. The former unicorn has now become an alicorn, and her ascension caused her body to skyrocket in growth.
Whatever was left of Ponyville was subsequently destroyed as Rarity's ass rolled over it like a great avalanche of snow; the sheer magnificent weight of Rarity's ass bore down into the earth, creating a deep crater. The residents of Ponyville were glued to her ass and pressed against it with her magic, allowing Rarity to unleash her weight upon the puny little ponies smothered under her ass. The little ponies groaned as the immense weight of her ass pressed down on them.
Rarity jiggled her rump from side to side; this resulted in her slamming her rump against those glued to the side of her cheeks. Her asscheeks clapped with a thunderous boom as she did this. Rarity also took the liberty of taking several ponies between her cheeks, allowing her to slam them with both of her buttcheeks. She giggled, hearing them squirm as her heavy ass bombarded their puny forms.
"Muahahaha! I am the apex mare, queen of femininity and power. I will consume this universe and beyond and smother all with my fabulous rear! Or should I say, flabulous!" boomed her even more mighty voice, which now could be heard faintly from distant planets in the galaxy. Echoing throughout the cosmos and shaking entire planets to their core. Leaving nothing unknown as her power was now able to be felt even by the lowest of peasants in a faraway world. Soon, all their worries would be gone as they would only be able to worship their new goddess.
Rarity casually reached down with her right front hoof and took a massive chunk of the earth below as if it were a slice of cake. Cracking it and pulling it out of the ground with a massive boom. Holding it in her hoof like she was inspecting a gem. Said chunk was the entirety of the Ever Free Forest. Automatically, with her magic filtered out, one being out of the forest, the zebra known as Zecora. Zecora was subsequently sent between her bubbly buttcheeks to be squeezed by them. Allowing Zecora to feel the bliss all the ponies in Ponyville were feeling at the current moment.
As for the non-sapient animals and whatever else, she did not care; she casually brought the piece of earth and everything else into her maw and consumed them. Rarity found animals to be dirty and unclean. She was unbothered by hearing them scream as her teeth crushed them. Turning them into more fuel for her growth. Rarity had always had a taste for the exotic, though this was quite interesting to you. You did not know ponies could eat meat, but Rarity had just proved you wrong. Rarity enjoyed her meal, chewing on the earth and animals in her maw. Once she chewed the 'food' in her mouth enough, she swallowed it down with a loud gulp.
She brought a hoof over her mouth to prevent herself from burping as she surged larger from the assimilated matter pumping into her body. Her whole body pulsing and thudding with magic as clouds of pure magic formed around her. Swirling around her like a light blue smoke from a forest fire and letting go of pure sparkles of magic which fell to the ground like snowflakes. With her magic, she then conjured a massive white napkin to clear off her face. This napkin was tiny in comparison to the rest of Rarity's body; it was just a paper napkin, after all.
She wiped her face with the napkin by using her hoof before beginning to put the napkin into her mouth and then eating it. This caused her to grow slightly from the relatively small amount of matter she assimilated. Nonetheless, Rarity smiled as she could now create matter at will if needed. Rarity could now grow endlessly, and she planned to do just that. Her horn started to pulse and glow with her light blue magic. The magic spilt down her horn and formed into a ball at the tip. Allowing her to cast a spell once more. What it would be, you would have to wait to find out.
Rarity's magic reaches out like an invisible hoof towards a mountain in the distance and grabs a huge amount of snow off the top. Forming it into a snow cone, with the mountain being the makeshift cone. Rarity then starts to slowly eat the ice and snow off the tip. Moaning and enjoying the coolness filling her mouth as she continues to grow. Her rump slammed into hills and turned them into flat plains, much like the plains of the Midwest United States, except without the fields of wheat and various oats. Rarity easily continued to dispense justice on the things that dared defy her with her endlessly growing marshmallow posterior. Leaving nothing behind but white, snowy softness in her wake as her horn continues to stretch higher and higher into the lower atmosphere.
Rarity idly sucks the fat out of the rumps of every mare she touches. Even affecting dragons and other female creatures. Adding their own rump's power to her own as she continues to flood the nearby area with her marshmallow-flavoured juices.
Rarity's juices form lakes of sticky goo that are impossible to move on and leave creatures in constant states of orgasmic blush due to her musk. Though none of the creatures were harmed as, Rarity wanted them all to watch her ascension as she grew larger and larger. Eventually, she had all of Canterlot Mountain between her massive mountain-like blubbery cheeks. Growing slowly over the city like a marshmallow eldritch horror. Leaving nothing left untouched by its power as Rarity giggled, feeling stallions and mares orgasm upon touching her soft pillowy buttcheeks.
The ponies, being surrounded by the mass of white rump, were unable to smell anything but Rarity's marshmallow-flavoured cum as it flooded under her rump like waves. Slowly battering the poor ponies and other creatures under her backside into sexy submission. Unable to think about anything else but pleasing the mare under them.
Rarity giggled to herself and then looked down at her rump. Putting a hoof on her marshmallow butt and feeling it sinks in deeper for several hundred feet before being pulled back. Returning back to normal after Rarity pulls it back with a sweet smile. Rarity then says with her booming voice, shaking the very bones of the ancient mountains of the world. It was like the very earth was speaking to the creatures across the planet. "Oh, my sweet darlings. Giving me such pleasure ensures I will keep you forever enraptured by my rump."
A bright and brilliant flash fills the air as a massive pair of pearly white and fluffy wings appear along the back of the massive mare. Rarity wailed in pleasure as she rapidly grew from the transformation into an alicorn goddess. Rapidly exploding like a supernova of growth and covering the entire planet with her rump. Forcing all under it into pleasurable subjugation to the new goddess. Rarity smirks to herself and giggles into the void. Looking out into the depths of space and licking her lips hungrily.
Her belly gurgling so loud it could even be heard in the depths of space. You continued to lay under her and worship her in awe. Unable to do anything but watch the gorgeous goddess continue to expand bigger and bigger. Her horn then flashed to light and formed a massive canister the size of her former home planet, starting to stuff her maw with the delectable delights within the cardboard ice cream container. The enormous silver spoon glowing in the sunlight coming from the glowing ball of plasma within space.
The deep blue eyes of Rarity slowly go along the void and see many stars out in space. Her tummy grumbles in response as she thinks about it before continuing to eat her ice cream slowly. Blushing deeply and moaning as she grows more and more. Pushing the planet deeper and deeper into her rump before it starts to fall apart.
Exploding more and more into pieces like an egg falling apart. Lava spewing out of the holes forming in the mantle as creatures desperately grab onto Rarity. Rarity keeps them safe from the rolling waves of the planet falling apart. Rarity continues to grow into the cosmos, and her ice cream continues to grow with Rarity as she eats it. Rarity happily smiles to herself and shows off her massive Venus sized teeth as she hums a tune to herself. Rubbing her butt against the remains of the planet. Her butt rolls back and forth before the world finally gives out under the strain. Turning into dust and turning into more growth power for Rarity. Rarity takes all the creatures from the planet of Equus and allows them to live on her massive white marshmallow butt.
Rarity was overjoyed she had every single male's attention dedicated exclusively to her. A few years ago, she remembered her friend Fluttershy was doing modelling. She remembered her jealousy from the lack of male attention and recalled herself saying, 'I'm the one who should be mobbed by strangers wherever I go.' Rarity smiled as she came back to the present and moaned deeply as she started to eat her ice cream even faster.
Clearly, she wants to continue expanding even faster as she rapidly starts to grow towards the closet planets and then uses her spoon to take massive chunks out of them. She shoved the pieces of world into her maw and chewed them up like they were pieces of cereal. Slurping up the lava within like it was milk and licking her lips clean. The body of Rarity acts like a black hole and starting to suck planets into her waiting maw.
That was then, now she had all the male attention from ponies and other creatures alike. All the lesser females were small, frail and bony thin. All the while, her fat ass dominated the entire world and soon even beyond. The rump of Rarity slammed into the sun that once dominated the sky of her home planet as she yelped in surprise. Then she looks down as her belly gurgles and sloshes deeply from the food within. Having taken over the whole solar system before Rarity had even really started growing.
She knew that she was destined to fill the entire reality she was in. She spread her white, unblemished wings and grabbed the sun in them. Easily covering the entire diameter of it while then bending down. She put her lips to the sun and started to slurp it up with a moan. Eventually, she swallows the whole sun like one long noodle of plasma as her body flashes with a massive glow. Rarity then has an enormous orgasm as her eyes close for only a mere moment. She then opens them, and her body has reached all the way across to the following system of planets. All of them fall towards her maw, causing a domino effect of unending growth.
Rarity was like the supermassive black hole at the centre of the galaxy at this point. An unending stream of planets was shattered by the pull of her gravity and turned into pure growth for her body. The growth of Rarity grows by factors unimaginable to the mortal mind. Like an eldritch being consuming everything within its path, but a caring one as she preserved the world's with sentient life on them.
Allowing them to worship her and orbit her as their new sun. Her massive body now pulsed with the energy of many stars and had a massive Goldilocks zone, which allowed the planets to live in her orbit without being affected. Giving no quarter to the stars of previously faraway systems and swallowing them whole like they were mere candies. Eventually, most of the matter in the universe had been consumed by the mare.
Her belly let out one last growl as she looked at the last thing she was yet to devour. The massive supermassive black hole which she could hold in her hooves like a toy. Its enormous gravity did not affect her as she shoved her head into it.
Her mouth pierced deep beyond the event horizon and into the centre of the dark chasm of the black hole. Starting to suck it up slowly but surely, like a sink drained being pulled, the black hole slowly disappeared into Rarity. Eventually, the gravity of the black hole gave out, and it exploded into matter. Allowing Rarity to swallow it all up like a vacuum.
The only thing left in this universe was now the massive marshmallow mare. She had eaten everything, and now her endless hunger was sated for now.
Rarity poofed up a massive couch and flopped onto it. She lay her head against the pillow and waved a hoof at the planets orbiting her. Saying to all her worshippers with her booming omnipresent voice. "I am quite exhausted after all that eating darlings. Your goddess must get some shut-eye. A mare can't not have her beauty sleep after all." the mare magicked up one of her famous eye covers and flipped it over her eyes. Closing them and deciding to go to sleep and wait for her to float along the endless oceans of space to bring her to the next universe to eat. Having had her fill for now, she would surely be even more ravenous than before once she awoke from her nap.
Rarity transported herself back in time; she was back in her humble boutique. Her torn dress was as good as new upon her body. Leaving her with a sweet smile on her face as she licks her lips.
Clearly enjoying the massive amount of power she has as, Rarity blushes deeply. You, the human, looked confused as the measuring tape was once again held in your hands as you stood behind the snowy white mare, who was now vastly reduced in size. Your mouth dropped open as you eventually shook your head. Coming back to reality and starting to put the measuring tape against her butt. She was only about 4 feet tall or so, but that clearly wasn't going to last long. You could feel the power of Rarity thudding through the air. Sparks flew around the air as it seemed to vibrate with Rarity's mere presence. Already, you see the mare was slowly inching upward into the air.
"Darling, please get my measurements right this time," Rarity said in a stern voice, even as her dress began to rip. Loud shrips fill the air as the butt of the marshmallow mare slowly expands out of the back of the dress. Massive parts of her rump expanded out of the dress like dough in a can when opened. The holes grow bigger and bigger with each breath of Rarity. The human could only look on in awe as her rump air ballooned bigger and bigger in front of his face. His hands desperately tried to hold the measuring tape on the constantly expanding rump in front of him. It was a losing battle for the human as the human sighed to himself.
As you took her measurements (tried to, at least), there had come a series of thudding sounds from behind you. A massive shadow loomed over the human as he let out an auditable gulp. His hands shiver as the human tries to continue his work on the dress, but it continues to push him back. Sweat poured down the body of the human as he put the measuring tape down. You turned around to see a massive, hulking dark purple creature.
You recognized this creature to be Spike, the dragon. Normally, he was with Princess Twilight Sparkle in Canterlot, but somehow, he was here now. Maybe Rarity had brought him here with that power of hers, though you would never know. Between his legs, he had not one but two barbed lizard light purple penises. The two penises were substantially larger than your own; they were practically about as thick as a Roman column each. Each throbbing and pulsing as they dropped pre onto the boutique floor and covered the room with his musk.
You stumbled a little as you became pushed forward as Rarity's rump violently surged in size from behind you. You fell on your butt as your eyes were brought back to looking at Rarity. The sheer amount of backside you saw caused an instant erection. Making you blush deeply like a tomato as the snowy mare shook her rump back and forth.
She shook the whole room with the loud clapping of her cheeks. A dark shadow loomed over you from the sheer size of her rump. You could see the walls of the boutique straining to hold the massive mare within; they were beginning to crumble, with dust and debris falling on the ceiling as her ballooning cheeks pushed against them. Massive cracks formed along the walls from the shaking of her rump and constant growth. The dress continued to let out strained hull noises as it ripped slowly more and more. There is no way you would ever be able to measure it now.
"On second thought, darling, be a dear and stroke my rump while this proper stallion mounts me," Rarity said in a hot breathy voice. Hungrily, she looks back at Spike as she growls at him. Giving him bedroom eyes as she bent down as much as she could. Her horn ran a massive hole in the ceiling as she bent down for several feet before she was in position for him. To add insult to injury, you could feel your penis rapidly begin to shrink before the majesty of the superior male and his two massive cocks. The horn of Rarity glows with her eldritch power as she grabs your cock. Slowly shrinking your cock as you desperately tried to rub the rump of Rarity.
Your whole body sinks into it like quicksand from your arm first. You, as the human, kiss her butt and worship it as best you can while Rarity then sits back on Spike. Covering you both in her massive white hills of her rump as Spike started to rapidly hump her butt. Shaking the whole room and cracking more and more of the room as windows exploded from the sheer pressure Rarity was putting on them.
During the fall of Rarity's ass, you found yourself lying on Spike's muscular chest. He was surrounded by his muscles, whose veins pumped blood along the sinews of his muscles. You could hear the rapid heartbeat and breaths of the dragon as he groaned and grabbed as much of Rarity's ass as he could with his claws. Leaving deep red marks on her rump from the force of his claws as you could see his veins bulge and pulse with power. Almost seeming to leap out of his skin due to the strength of his muscles. Your head was absolutely dwarfed by even the wrists of Spike due to the mountain of muscle he was.
Your pathetic one-inch micro penis prematurely ejaculated upon her fat bubbly ass as it smothered you. Your cum not even making a mark on her rump due to how pitiful it was. You hissed in pain at the great weight of her ass bearing down on you. The strong Spike could withstand the ass as his two great massive pillars of cock came plunging into Rarity's depths, double penetrating her succulent marehood. His powerful clawed hands gripped her gargantuan backside even harder, creating two deep depressions upon her cheeks. You squirmed beneath Rarity as your tiny, painful erection continuously ejaculated upon her ass. Unable to cease ejaculating due to the immense mind-searing pleasure you were having going directly to your brain.
Rarity lifted her massive rump into the air. Her massive backside jiggled and shook even with this slight movement. You could see the enormous amount of muscles under all the cellulite on Rarity's rump. Rarity was enjoying herself, you could tell. She had a big, goofy smile on her face while she bounced up and down. Humming a happy tune to herself, which was drowned out by the shaking of her ass. Rarity's ass muscles bulged and moved back and forth in front of your eyes like worms of pure strength. Undulating back and forth in front of your eyes as you moaned deeply. Sporting a super long rope of cum onto her butt, even from your small penis. Making the slightest dent under her rump before it was covered by her growing butt.
She needed it all to lift the hundreds of tons of ass she had now. Rarity looked back over her shoulder and down at Spike and you. Winking and licking her lips hungrily, giving you both bedroom eyes. Before, with a giggle, she dropped it down upon you with a heavy slam, knocking the wind out of you.
Shaking the whole boutique once more and shattering the last of the walls with the shockwave. Blowing away the walls like a bomb going off in the room. Leaving you exposed to the elements under her marshmallow rump. She soon did the same thing again and again and again.
Rarity's asscheeks came repeatedly slamming down upon you like two super heavy anvils of ass. Spike could withstand her as he, too, began to grow larger beneath the mare. Though you were left unable to deal with the amount of ass that was being bounced on you. She shook and jiggled around you, which left you completely blinded to anything but her white rump. Looming over you both and casting a massive shadow over the local area. Giving all of Ponyville a great view of her growing white cheeks. Spreading her marshmallow-like buttcheeks while moaning loudly into the air. Shaking the whole town and making all of them crack from her voice.
"Oh yes, Spikey-wikey! You are so much better than that human!" she moaned loudly.
You could only whimper in response as your pathetic micro penis continuously prematurely ejaculated upon her ass. Spike, meanwhile, merely responded by pulling his right hand back before delivering a hard slap to her rear. Rarity moaned as her butt jiggled from the impact, this was followed by a mass surge of fat pumping into her ass.
Her massive snowy white butt bounced about as massive migrations of fat flooded into it, creating a thunderous meaty clapping sound as her fat bubbly cheeks clapped together.
You could feel Spike's chest underneath you rumbling as new layers of muscle became added to his physique. It was as if his body was knitting new muscles from nothing under you. Rapidly pumping up as he grunted and groaned from the new muscles. As the dragon moaned and growled as he feverishly humped his cocks up into her marehood you heard his voice getting deeper and deeper as he grew more and more.
Spike's cock continues to leave yours in the background and dwarfs yours more by the minute. Spike's whole body shook and sparking with green draconian energy as he grew. His whole body thudded and pulsed with the very power that was growing in his body.
The massive cocks of Spike continued to slam into the ass of Rarity as he fucked her as best he could. Rarity let out loud moans and screams of pleasure from Spike fucking her rump.
You had no recourse to stop this at this point due to the raw power imbalance. In front of you could see his two rising pillars of cock getting bigger and bigger, leaving you in the dust as your puny micro penis barely made a dent upon Rarity's massive ass covering the entirety of his body and yours laying upon his chest.
You, as the human, were left a blubbering mess as you had never ceased constantly cumming onto the ever-growing marshmallow rump above you. The constant sounds of flesh slapping against flesh drown out your loud screams of pleasure.
Your whole body sparked with endless pleasure like your body was in an iron maiden of orgasm milking. Unable to stop cumming as your body shivered and shook. Your balls are throbbing in pain due to how many times you have cum by now. Hundreds of orgasms had racked your body already, with only more coming.
You whimpered in your pathetic state as you continued to prematurely ejaculate upon her rear. You were used as mere growth fuel for Rarity, while her real lover Spike outclassed and shamed you in every way. Spike continued growing stronger and stronger, you could feel his muscles rippling profusely against you.
You can see the great towers of his two cocks growing taller and taller, thicker and thicker without stopping. All the while, your puny body was continuously bombarded with greater and greater amounts of ass from the growing mare bouncing on top of you. You could only take comfort in the fact that Rarity's ass was very beautiful as you watched it get bigger and bigger. It was strangely hot watching Spike mounting it with greater and greater cock, something you would never have the privilege of ever doing.
