Grow

The massive lavender unicorn known as Starlight Glimmer anticipated the arrival of the newcomers of Twilight Sparkle, Applejack, Rainbow Dash, Rarity, Fluttershy, and Pinkie Pie to talk with her for a small meeting for divisions of her town. She paced back and forth, her hoof-steps could be heard from a mile away or so. Starlight Glimmer’s ears flickered as the noises of the Elements of Harmony came closer. She stood at least 30 feet tall. Her legs in terms of thickness were like that of Roman columns. Her towering rump was huge, like that of a blimp each. Her gigantic rump was like great round bubbly masses of spheres as it bounced after she sat on the ground.

Her tail wagged excitedly like a dog. She can’t wait to dominate her new friends. She loved the feel of tiny stallions below her, humping her hooves beneath her. Her hooves were stained with creamy stallion spunk as they relieved themselves on her. They were so cute. They were only becoming more and more inadequate as she became ever bigger over them. It was thanks to her new spell. Everyone in the town worshipped her.

They gave her insignificant growth. She needed more. Much more! It was at a snail’s pace at the moment. But it was a sign of things to come. She will bring happiness to all, and wrap them in the warm and soft embrace of her rump. She lay backward with her huge body spread out with them wanting to hump her stomach exposing it to them. She moaned aloud as they had their way with her.

“Grow me, my people. Give me more of your affection,” she moaned. The weight of her heavy rump dug deep into the earth underneath her. Cute little stallions and mares alike lay smothered under her soft, bubbly mass over them.

They remained unharmed, even as several dozens of tons of weight pressed down on them. Starlight moaned heartily as she began to gain several inches into the air. Like an inflating airbag her rump behind her grew larger, it rippled like jello and created a delightful meaty slapping sound as her buttcheek came to slap against the other one with a wonderful sound of flesh, slapping against flesh.

The more she grew, the better and better it felt. She now stood 35 feet tall. She grinned in delight as her new size peaked.

However, she soon sighed deeply, it was just so slow for the moment. Like a waterfall, her creamy marecum flowed out of her pussy, soaking the town’s ponies underneath her. She giggled at the sight of herself cumming on her town with her pussy. Her marehood winked so much it unleashed more and more of her orgasms out of her body, soaking everyone and everything in thick blobs of her creamy, reproductive essence. It smelled of sweet strawberry juices, her cum was sticky like glue in a way.

With each new inch she gained, she felt herself become both stronger physically and magically. None will oppose her. “I will bring happiness to all, and protect them from a cold, bleak universe that does not care about them.”

Starlight began to grind her hips back and forth over the ground with her back hooves pushed down and lifting herself up as yet more growth flowed through her. Like an inflating balloon, her buttcheeks spread across the street, it jiggled wildly on the ground back and forth, quickly advancing towards the buildings on either side of her town. As if she was a bulldozer who came to push against the buildings. The soft bubbly flesh of her cheeks began to depress deeply against them.

Her divine, omnipotent butt only got bigger and bigger, fatter and fatter, heavier and heavier, wider and wider. Creaking can be heard in the village as the buildings gave way to her massive body. Planks of wood were sent flying far and wide from all around her as her bubbly cheeks tore the buildings around her asunder. Some of these blanks did indeed hit ponies in the town, but they harmlessly bounced off them. Starlight could not bear to hurt anyone. Her powerful magic protected any and all from harm. Starlight wanted to be a force for good, yet a sexy force for good after all.

She now weighs 60 tons, causing the ground to rumble under the town’s houses, then she thought it would be fun to play with her massive rump while she’s at it, she pushed her rear end at those ponies' faces squishing them. Her rear end pushed some buildings out of her way with an oversized bulldozer of an ass in the way of her pleasure.

She pushed her asscheeks again moaning in delight at her oversized, monstrously wide hips with her ass being the biggest of them all when they say you have too much in your trunk.

“Mmmm… bigger,” she moaned. A low rumbling sound came forth a buzzing feeling in her gut pushing her size another 10ft pushing her fleshy rump over most of the back houses.

It stretched her back with that inch earlier from last time she moaned loudly “Ahhh worship me your pony of lustfulness!” as her voice boomed at her villagers.

“This was only the very beginning, soon I will dominate all and everyone will love me. My conquest will not leave a single insect harmed!” Starlight sat down with her new big bubbly rump to make those ponies want more of her butt and body as she pushed her pussy in front of them. “All will be made equal! Equal as cute bugs under my massive divine ass!”

The feeling of being huge turned her on even more so. Feverishly, Starlight Glimmer began to grind the plump, nether lips of her thick and meaty pink vagina with her hoof. Her hoof created a loud clopping sound and a wet slick sloshing sound as it moved back and forth. Her hoof was soaked in thick globs of her creamy essence. Starlight for her part was moaning in pure bliss as she gained inch, after inch by each passing second. Her skin tickled from being stretched in height feeling the intense masturbation session still going. It just felt better and better as her vagina gained more and more surface area for her hoof to grind against.

“Mmmmm! Yes! Bigger! Bigger! Help me grow bigger, my faithful!” she cried out.

Her musky scent could be smelled for miles around. The main six smelled something off as they got closer to the village.

The main six could hear Starlight’s voice whispering into their minds. “Worship me. Trot over to me.” Twilight watched in shock as her friends seemed to turn into a zombie-like state as they obeyed the command of the voice.

Starlight stood up over them. Her hoof was still glued to her soaking wet pussy. She feverously masturbated in front of them. She stood over 70ft in size. They trotted forward to answer the call of Starlight Glimmer.

“Your resistance only turns me on even more Twilight. I will enjoy making you submit to me,” Starlight said as she stomped her hooves loudly at them, two huge asteroid-like craters were formed in the earth from the impact. Wiggling her giant rump in the huge crater in the ground, Starlight wanted their attention by twerking her ass up and down on the ground making her ass move hypnotically at them with her pink asscheeks.

“I just keep getting sexier and sexier the bigger I get!” she moaned out aloud.

Starlight made to stand up and turned around, and subsequently presented her massive rump to Twilight. Each cheek of her tremendous rump was like the size of The Lavender Spirit blimp. Starlight Glimmer’s huge butt moved from side to side, smashing together as her massive blimp-like ass was wiggling and jiggling like jello and cloth.

Starlight began to swish her cheeks from side to side. It was hypnotic, every single pony in the vicinity was staring at an absolutely wonderful ass. Her butt cheeks came to slap against the other one with a delightful sound of flesh slapping against flesh.

Twilight’s will to resist her was already breaking. Starlight could see her bringing her hoof behind herself. From there, she began to grind it back and forth against her soaking wet marehood, moaning in pure bliss all the while she stared at Starlight’s magnificent rump.

Starlight reached backward and placed her right hoof upon her grey, equal cutie mark. She watched in delight as her heavy hoof sank into the squishy softness of her bubbly cheek. It created a wonderful deep depression. She held her hoof there for a good few seconds, before slowly pulling back and looked on in joy as the depression began to slowly fade, and return into a perfectly smooth shape.

Her massive ass again jiggled like jello as it moved over the town that once was one but now a completely flatten one under her great weight moving over them with thousands of pounds of fat muscles as more and more of her soft, warm, bubbly mass grew out of her. Her enormous rump wiggled around on the ground. Her massive bubble butt just hasn’t stopped growing, she thought of going more out of control with herself. She needed more size, more bulk, more fat, all will be smothered by the great warm softness of her buttcheeks rolling over them.

“Oooooohhhhhh! Yesssss! More! More! More! I can never be big enough!” she simply cried out.

Her marehood was dripping wet, flowing down like a creamy waterfall. Everypony, apart from Twilight, drank up her creamy essence with gusto. Then she let herself finally fall which made her gargantuan rump begin to dominate those under her. Her rump pounded the ground like that of an earthquake. The shaking ground caused the ponies to fall over their hooves.

Starlight moaned in delight as the ponies worshiped her divine rear. She felt their tiny hooves pushing against her bubbly softness smothering them. They fondled her ass with love. They kissed, licked, and humped against her. They pressed their hooves into the thick softness of her tremendous rump. Stallions were lost in the moment, As they frantically humped their large cocks against her massive rear. Big as their cocks were, they were only becoming more and more inadequate the bigger she got.

“You are all so cute and puny before me! All of you will know the warm embrace of my massive rump,” she boomed. “You shall not be more powerful than me now! I will continue to grow bigger and bigger, stronger and stronger with each and every inch added to my body.”

Her hoof came to slap her over-inflated ass and caused it to bounce wildly, jiggling with loud meaty slapping sounds as her cheeks smacked together. The flesh of her expanding buttcheeks pushed through the townhouses and made them go boom as her pressure pushed onwards causing houses to burst into rubble. The destroyed houses was no match to her body's superior rump of love and destruction.

Twilight quickly surrendered to Starlight Glimmer and proceeded to worship her. Starlight felt her hooves prodding and squeezing, the pillowy softness of her monstrous rump sitting upon her.

“Twilight comes forth and be squeezed under my dom form. You will play with my asscheeks.” Starlight boomed. “You all shall be equally insignificant under me!”

With a flash from her horn, Starlight stripped the entire mane 6 of their cutie marks and replaced them with a grey equal symbol each. She felt her growth had become stronger than ever with the mane 6 subdued. What was left of the town was simply destroyed as Starlight’s bubbly cheeks came rolling over it. Everyone in the entire town was soon submerged under her colossal rump. The sheer weight of her huge rump created a deep crater in the earth as she expanded over the desert wasteland around her.

Her expanding bubbly mass, soon crushed the train into a fine pancake from her new great weight. Starlight Glimmer grinded her massive rump over the train tracks. Her growing body was now 90 tons, already too much weight for the train tracks as her size was so big it took over a few hundred acres of trees and mountainscape.

Her humongous rump rolled over the train tracks, slowly advancing to distant settlements. Many ponies fled in panic and screamed as they tried in vain to run away from her. However, many ponies embraced the incoming bubbly mass coming toward them.

With that, Starlight wanted to show off her new self by twerking in front of ponies with her 90ft self moving herself back and forth for attention. Her gigantic rump bounced and squatted in the town and most of the outskirts of Equestria. Her giant pink asscheeks already smashed over most of the town. The sound of her thunderclapping buttcheeks could be heard across the land. Only becoming louder and louder as it grew ever bigger.

These new worshipers simply lay themselves down and submitted to their fate. This added yet further growth speed to Starlight Glimmer as she fed on the worship of her. Those who resisted were simply swallowed by the expanding mass of her massive rump. They would become new worshippers in mere seconds, which only helped fuel her growth even more.

Starlight laughed maniacally as she gained new worshippers. “Mwahahaha! Resistance is futile. All will know the warm embrace of my enormous rump!” she boomed.

Her 120-ton ass came crashing over trees and the landscape below. She twerked on them for her pleasure. She giggled as she saw her gigantic rump grind down rocks into dust, and trees into mere sawdust.

Starlight craned her neck back and uttered a deep, throaty moan. She rocked her hips back and forth grinding the pitiful earth beneath her with her mighty buttcheeks. Starlight expanded and expanded over the continent of Equestria. Her asscheeks again cracked bigger thunderclaps breaking new records. She stood up to see how much she had left to grow on her ass, having developed much in size, making it look like two huge overgrown mountains in the shape of round, bubbly blimps.

The sheer thickness of her legs resembled that of nuclear power plant cooling towers, but on steroids. The gap between her buttcheeks was like that of a wide canyon pass. Her huge, plump marehood and ponut were like two gaping asteroid craters. And they were only getting bigger and bigger, as Starlight kept growing and growing without end. No stallion in Equestria had a big enough penis to please her, and that's just the way she wanted it. Her growth alone provided her with all the sexual stimulation she needed.

“I guess Princess Celestia, Princess Luna, and Princess Cadence can’t beat me now,” she said, giggling with a hoof over her mouth.

Starlight Glimmer then wanted to rampage over Equestria standing on her 4 quad hooves and massive asscheeks 120ft of pink-skinned pony she was. She slowly stomped over Equestria, crushing everything with her hooves. With each and every powerful stomp of her hooves, it left huge asteroid-like craters in the earth underneath her. She could do this freely without care, knowing that she could not harm anyone.

Starlight dropped her massive ass down upon Equestria, covering nearly the entirety of the land. She turned her head smiling at the sight of her butt getting heavier over those small ponies under her.

She grunted at her next growth spurt “Oooooh!” she moaned heavily at her next growth, her ass expanded outwards going over the mountains pushing around 200ft as her buttcheeks bounced on them. Her legs tickled as her height pushed on to 200 tons, then 400tons, all the while her belly inflated like a balloon.

Starlight giggled, feeling up her bloated stomach with her two front hooves. She moaned in delight as her hooves sank into the plush softness of her belly. With a flash from her horn, she deflated her belly. Her belly became rather flat, but she sent the fat hurtling into her already massive ass to make it grow even larger. Her massive rump was now cartoonishly bloated out and looked quite disproportionate when compared to the rest of her body.

She groaned at her quickly growing body. Her head pushing up and her neck growing longer over her front sides. Her growing buttcheeks advanced over mountains, flattening them down into pancakes. Her head began to move up towards the clouds.

Eventually, she had the entire continent of Equestria smothered under her ass. Millions of ponies were subsequently trapped under the heavy mass of her buttcheeks. The sheer weight of her massive rump caused her to dig deep into the ground towards the planet’s mantle underneath. With her magic, Starlight subsequently turned the lava into a soft warm marshmallowy substance. She didn't want those she was facesitting on to feel uncomfortable.

Her immensely heavy rump pressed down upon them. Quadrillions, upon quadrillions of tons of weight, pushed down upon them. They squirmed helplessly beneath her, trying in vain to give her pleasure with their insignificant penises. Not that it mattered, Starlight Glimmer got all the sexual pleasure she needed from simply growing. Nonetheless, she appreciated their worship of her. They were, after all, helping her grow faster.

“Mmmmmmmm! Yesssssss! Bigger! Bigger! Help me grow bigger!” she boomed, her asscheeks inflating like giant blimps like an over-inflating balloon. Her cutie marks stretched so much it looked like two moons attached to her ass with a pink glow to them. With a musky smell afterward, really strong sweating glands in her asscheeks. Cum kept dripping from the heat she was producing now.

Starlight's new god-like form loomed over Equestria, her butt and body moving around it. Her ponut and pussy faced in front of Equestria. The heat was felt in her lower body. Particularly around her ponut and marehood, they will act as their new, twin suns.

She transformed the planet underneath her into a flat, disc shape. So all will know the softness of her colossal rump over them. Starlight sighed happily as she felt her huge rump advance over the ocean, the cool water giving her a mini cold shower. The water was very cold and wet as her size became huge and unable to be contained. Her soaking wet marehood polluted the seas, flooding them with her creamy essence.

In no time at all Starlight had the entire planet submerged under her humongous rump. She licked her lips at the surrounding planets of the solar system. Starlight wasn't playing around anymore, however. She needed true size.

Starlight flashed her horn and began to hyper expand her body faster than ever before. Within a manner of seconds, she became hundreds of times bigger than Equus, becoming a gas giant of a pony in space.

She transformed the planet back into a round shape and undid all the damage she had done to the planet. With her magic she gently tugged the planet between her massive buttcheeks. The planet looked as if it was a little tiny little ball between the god-like cliffs of Starlight's buttcheeks.

She squeezed her asscheeks together, sandwiching all between her wondrous buttcheeks. Starlight giggled with a hoof over her mouth as she felt millions of voices crying out in pure bliss as her warm, bubbly softness smothered them. Starlight uttered a deep throaty moan as her vagina unleashed a violent explosion of her creamy marecum upon the planet. The oceans of the planet below became subsequently flooded with her creamy marecum.

Starlight licked her lips and began to pull the planet towards her vagina. Her vagina was so large that it was easily able to take it into her without any issue. Once the planet was sufficiently deep inside her, she proceeded to clamp down hard upon it with her strong vaginal walls. Her soaking wet marehood drenched the planet with even more of her creamy marecum.

She opened her mouth wide and pulled the sun towards her. Compared to the sun she was a little speck. Even as she stood about the size of a gas giant, making her at least 1000 times bigger than Equus. She simply compressed the sun down into a small football and swallowed down the spicy meatball of star matter into her mouth.

Starlight’s cutie marks glowed with blinding light as she subsequently went supernova in growth. Her hyper-expanding body came crashing against planets as if she was a cosmic tidal wave. The solar system was no more, it was little but space dust. She teleported billions of alien species onto her body for safekeeping, to ensure nobody would be harmed. With the threat neutralized, she could unleash her true power without worry.

Starlight flashed her horn, increasing her expansion across the great distances between stars to reach other solar systems. She giggled as her astronomical rump’s cheeks simply smashed into the planets, leaving them little more than cosmic dust splattered across her rear. She lifted thousands of nearby suns and pulled them toward her gaping maw. The suns were so tiny at this point to her, they might as well be marble candy. Each sun she swallowed into her caused her to have a violent surge of growth.

Starlight’s eyes widened in delight as she eyed the supermassive black hole at the center of the galaxy. Starlight swam towards the center of the galaxy to feast on the delicious matter. As if she was a black hole she simply sucked the matter of the black hole into her mouth.

Starlight cried out and unleashed a massive explosion of her creamy marecum into the cosmos, soaking every planet in the entire galaxy. These planets were soon destroyed into a fine dusty powder as Starlight Glimmer exploded across the galaxy, destroying everything in her path. Starlight was now expanding into dark space beyond the galaxy’s horizon. The massive galactic mare raced towards distant galaxies, quickly closing the distance between her and them.

Starlight’s rapidly expanding buttcheeks jiggled widely about like a stormy ocean. Tidal waves of fat raged across her celestial rump. Her bubbly cheeks came to repeatedly slap against one another. The thunderclap of her buttcheeks could be heard far across the universe.

Starlight teleported aliens from tens of millions of galaxies onto her astronomical rump to keep them safe. No sooner had she had done that than her rump smashed into nearby galaxies and utterly destroyed them into cosmic dust. Starlight moaned in bliss as she sucked up the dusty remains of the galaxies from all around her.

Galaxy after galaxy became consumed within Starlight Glimmer. With each and every galaxy eaten, she gained quadrillions of new worshipers to help her grow even further.

Soon, the universe itself began to run out of room as Starlight Glimmer’s bubbly mass swallowed up the last remaining galaxies leaving nothing but darkness. Starlight frowned, was this the end?

“This can’t be the end? Can it?” she said in a worried tone.

But then, she felt her rump bump against something. An invisible barrier at the literal end of the universe. As if the universe was a pair of tight pants for her, they began to rip and tear at the seams. Before ultimately the barrier was torn into pieces.

Starlight had become a universe unto herself. She floated in a dark void surrounded by transparent spheres, each one containing a universe. She was now in the multiverse. She licked her lips at the tasty universes from all around her.

She compressed down the universes into small marbles of matter before funneling them into her mouth. Starlight’s body went into overdrive of expansion as she swallowed universe after universe into her. At some point, she had become so large that she didn't need to compress down the universes, and simply inhaled them into her. Any and all life forms from these universes were teleported onto her rump to join the others.

The universes from all-around her began to turn into little specks of matter, becoming more and more insignificant as time went on. She hardly even noticed when she came to crash into yet another barrier of existence.

She now found herself in the omniverse. She was surrounded by transparent spheres, each one containing quadrillions of universes inside them. They were multiverses. However, Starlight had become so large at this point they were little but marbles in comparison to her, and were only becoming lesser and lesser as time went on.

Starlight Glimmer devoured the omniverse from all around her, sucking up the delicious matter to help her grow and grow. To her absolute delight, she was growing so fast that she found herself bumping against yet another barrier of existence. It seemed within a matter of seconds she had nearly devoured every single multiverse in the entire omniverse as if it was nothing to her. Her stomach growled for yet more matter to eat.

Her buttcheeks began to get squished against the literal end of all existence. The infinite thicknesses of her squishy soft buttcheeks, deeply depressed against the barrier. The squishy soft flesh of her rump was being pushed back deeply as they pushed against the walls of the omniverse.

Starlight moaned in pure bliss. She felt like she was being hugged by the barrier as her bubbly, fleshy body was compressed against it. The barrier held strong for quite some time, before ultimately fading away as if it was nothing.

Starlight now found herself floating in an empty white void. She had reached beyond the end of existence into simple nothingness. However, her magical sight allowed her to see that this place wasn't quite empty. She could see an invisible swirling singularity attempting to recreate the old omniverse she had just destroyed.

The Big Bang was all hers for the taking. Thinking quickly, she used her magic carefully to shift the focal point from where the omniverse would have been, slowly into her mouth, down her gullet, and into her belly.

Then, her body was rocked with a great explosion, all her previous growth seemed to be in slow motion. Starlight cried out aloud in pure bliss as her body cartoonishly grew out into the void. Her belly began to inflate as she became pregnant. The two bubbly spheres that were her crotchboobs began to hyper expand like bloating airbags.

With a loud cry, a huge transparent sphere covered in her marecum came shooting out of her marehood. This sphere contained quadrillions of tasty universes for her to eat. With a gentle tug of her magic, she pulled this multiverse toward her gaping maw. She moaned heartily as she swallowed down the multiverse into her, her own marecum acted like a sweet and creamy sauce to flavor it.

Great tidal waves of fat raged across her rump as her rump jiggled better than ever before. The jiggling became ever more intense as she became ever bigger. The Big Bang repeatedly went off inside her as it attempted to recreate the old omniverse she had destroyed.

She suddenly frowned, big as she was, the size difference was still not good enough. So with a flash from her horn, she shrank down every living thing into a quark atomic level. Starlight wished she could make them even smaller, but it was literally the limit.

Starlight Glimmer sighed sadly. The white void mocked her, she wanted to fill it with her mass to see if it even had an end.
