Sunbutt Apocalypse (Co-Author: Glitter Grenade)

Sunbutt Apocalypse

On a wondrous lavender night in the magical land of Equestria, the beautiful alabaster alicorn known as Princess Celestia was fast asleep in bed. She breath quietly in her sleep, her chest slowly rising and lowering as she took life giving oxygen into her powerful alicorn lungs.

The mare moaned in her sleep, quietly muttering something about ‘cake’, before her lips curled into a smile.

Judging by the long and wide bed she lay upon, she was quite a tall and imposing mighty pony, but when she is sleeping, she is so cute. Not to say, she isn’t cute when awake and wide-eyed but she’s just a really, really, really big pony. Standing at nine foot tall, two inches, not including her horn, made her one big pony. Her little pony subjects, only standing at merely four foot tall on average made her one big mare one would not want to piss off.

Despite her large size, she was generally a gentle giant. Of course, if one tried to hurt her or her subjects, one might end up being bucked by her hooves. Said hooves strong enough to easily break the hardest diamonds known to ponykind.

If one plays their cards right, by treating her with respect, dignity, kindness and making her laugh, one may even get the chance of partaking of her royal booty. Very few ponies had the chance of tapping the royal rump, because for some reason this pony has some odd fetish for strange, sapient hairless ape beings, which appear in Equestria every few centuries.

The immortal alicorn would mourn the loss of her many mortal lovers (most of them being those hairless apes) by visiting their graves and leaving flowers. She held onto the memories of them, remembering the good times when they were young and strong, and the many nights of passion they shared together. But also the hugging, kissing and the nice belly rubs they gave her.

Along with the sad ones, when they were old and grey, where she gave them one last tearful kiss goodbye just before they closed their eyes.

Celestia never gave in to the bitterness of her immortality. She would move on and find a new lover eventually.

Yet, she never forgot her long dead loved ones due to her photographic memory. Unfortunately, this led to rather awkward moments, when she’d accidently call out their name during the throes of passion with her latest love.

Tonight, there was no such lover beside her. Over the millions of years she has lived, this was the same bed she did the horizontal monster mash in with a many lover… sometimes more than one lover at a time. A bed where she lay with over sixty five million lovers… ninety five percent of which being those hairless apes.

The white mare moaned in her sleep, muttering something about ‘Mmm hands’, ‘Stick your fingers in me you sexy ape’ or ‘ride me like one of your earth horses’.

Abruptly, the mare rolled over onto her chest, raising a round, massive mass high into the air. Consequently, this caused her blanket to fall off the bed, to reveal two glorious mounds of fat snowy white flesh of her enormous butt

Her glorious, towering rump was the most the loved booty in all of Equestria. Her round, thick fat cheeks were perfectly smooth and so plump. The only downside she was very… very heavy back there. So heavy infact, she accidentally broke the legs of her first love when they tried the cowgirl position.

Sure, her first lover was able to walk again after a week's worth of healing magic, but it really upset her to see her lover get hurt so badly. Ever since then she used weight suppressing magic to protect her lover’s pelvis.

But not too much weight suppressing magic, for she liked to see her lovers’ fearful squirms below her. Loving to see the reaction on their faces from being overwhelmed by the sheer size and weight of her massive rump sitting on them. Laughing at them as they made a pitiful attempt to try lift her immensely heavy butt.

For the next several hours, nothing really eventful happened. Other than her muttering about ‘cake’ and ‘give me the monkey dick you sexy ape’.

However, something rather odd began to happen at the early twilight hours before the dawn.

It was barely noticeable at first, but as if her royal posterior could not be any more glorious… it began to grow. By mere centimeters, slowly rising higher into the air and growing thicker and fatter by each passing second.

"It begins! Soon, all will love Sunbutt!" boomed a loud deep voice from Celestia’s asshole, which was remarkably similar to Celestia’s voice, but slightly deeper.

Suddenly, her hindquarters rippled in ecstasy as it bloated outward like a balloon. Her ass was now disproportionate to the rest of her body, but her butt didn’t care. Her butt only wanted to get bigger and bigger, fatter and fatter and heavier and heavier.

"Mwahahaha!" her expanding ass laughed maniacally, "All will praise the sun!"

A moment passed. There was no prasing of the sun. Her ass, though slightly bigger, was still not the size necessary for its nefarious plot.

Her butt sighed sadly, seeing that she was now growing a mere inch a second.

Little by little, her glorious derriere expanded over her bed, growing slow and steady, biding its time, before the real expansion begins.

Suddenly, her anus glowed in a faint golden aura.

"At last! I’m big enough for my Buttmagic to activate! The bigger I get, the more powerful my Buttmagic shall become!" she shouted excitedly.

The blanket beneath her became wrapped in the same magical aura from her butthole, a moment later it was pulled out from under her, before being levitated before her asshole.

"Blanket, you shall have the honor of being the first to speed up my butt’s growth."

There was a blinding flash of light from her butthole, when the light faded the blanket was converted into a large white chocolate cake.

"Get in my butt! Make me bigger and fatter!" her ass shouted, pulling the cake toward her wide gaping hole.

Unfortunately, her butt still wasn’t big enough to swallow it entirely.

"Oh buttfat! I’m still not big enough to swallow cakes whole!"

With a sad sigh, she sliced the cake up into small pieces, before flying them into her asshole. Once the slices of cakes were inside, her massive buttcheeks began slapping hard against one another, the fat jiggling as she did so.

“Mmm! Om nom nom nom!” her butt moaned in pleasure whilst she ate the cake.

Her giant cheeks continued to slam into one another in order to simulate chewing as if her ass had a mouth, all the while her butt swelled in size by several inches due to the fattening cake.

“MORE! GIVE ME MORE!“ her ass roared.

Her asshole flowed with golden light, lifting several books from a nearby shelf, before converting them into small chocolate cakes.

Without a word her butt flew the cakes into her asshole, cheeks slapping against one another as her butt ate the cakes, her rump rapidly fattening up as she did so, to the point her flanks had become so wide, they were dangerously close to falling off the bed.

With a flash of light, the bed beneath her was teleported away, as a result her massive ass slammed hard upon the marble floor with a loud bang, creating large cracks due to the sheer weight of her butt.

Despite this, Princess Celestia herself was still asleep, however she had a very strained look on her face.

There was some shouting outside, before two royal guards stormed into the room, one a unicorn the other a earth pony with both their spears raised high.

“Princess?! What happened?! Are you in…. “ the unicorn’s eyes widened upon seeing the giant butt rapidly filling up the room. “Look At Dat ASS!“

“Embrace me, handsome stallions! Shout ‘praise the sun’ to receive my love!“ her ass roared.

The earth pony shouted, slapping the unicorn across the face. “Snap out of it! Something clearly bad has happened to Celestia!“

"But I like big butts! This is my dream come true! I willingly want to do this!" he yelled.

"Yes! Don’t listen to that small butt loving heretic! Embrace my ever growing butt and live forever on my giant butt!"

"Praise the sun!" roared the unicorn with his hooves raised high in the air.

With that the unicorn’s body was wrapped in a golden aura, before being lifted in the air, followed by being placed upon her massive right buttcheek. The moment he landed upon her rump his eyes lit up with love hearts, before he began humping like a maniac against her cheek.

""YES YES!" her butt cried out in pleasure. "Worship my big fat butt with your tiny cock my little pony!"

"This is insane! Princess Celestia what’s happened to you?!" roared the earth pony.

"I am not Princess Celestia! I am Sunbutt! You must praise the sun or you will be eaten to make my butt bigger!" she shouted.

"No! I will find a way to stop you!"

"Last chance. Praise the sun or you will die!" she roared.

"Never!" he shouted in defiance of her massive butt.

"You die now heretic!" she boomed.

His body became surrounded in a golden aura, his screams of terror were cut short when her butt turned him into a chocolate cake.

Without a word Sunbutt levitated the former guard turned cake into her gaping asshole, her butt exploding outward in size as she did so.

"The fate of all heretics that refuse to praise the sun!" she bellowed.

Her flanks were now so wide, the silky soft fat was being compressed due to them pushing against the walls on both sides of the room.

There was a loud rumbling sound, before the floor suddenly gave way. With a loud crash Celestia’s butt landed in the middle of the massive throne room, creating a large crater. Large chunks of rubble fell from the ceiling, harmlessly bouncing off Celestia’s giant butt. Celestia herself was still fast asleep, snoring loudly.

Dozens of the royal guard immediately rushed to aid their Princess, gasping in shock seeing one of their fellow guards grinding his cock against her cheek.

"Stop humping the Princess!" the guards roared.

"No! Join him! Embrace me and live forever on my ever growing butt!" Celestia’s butt boomed.

Miraculously, all the guards roared in defiance by shouting ‘No!’, even as she telepathically spoke to them through their minds with a quiet whisper of the words ‘Cry out praise the sun and you will be spared’.

"HERESY!" Sunbutt boomed in the traditional royal canterlot voice. "One of you will be made an example of for your heretic ways!"

"Come on Celestia! Wake up!" an unicorn royal guard roared into her ear.

"You dare try stop my butt from growing?! You shall be my example!"

The guard was lifted into the air by a magical golden aura, he screamed, struggling to break free from her magical grasp.

"Save him!" one of his comrades roared, blasting Celestia’s butt with spells and stabbing it with their spears. Neither of which did anything at all, not even leaving a scratch on her rump.

"Mwahahaha!" her growing ass laughed maniacally. "You cannot stop Sunbutt! Now watch as I eat your friend!"

With a blinding flash of light, the guard held in mid air was turned into a chocolate cake.

The guards gasped in horror seeing their fallen soldier now a cake being levitated inside her giant gaping asshole. Like a sucking black hole, the entire cake was swallowed with one gulp.

"Run for your lives!" a guard shouted.

The guards screamed in terror, trotting away with their tail between their legs.

"Mwahahaha! You can’t run forever! Soon all of Equestria will fall before Sunbutt!" she boomed.

"Not if I have anything to say about it!" boomed a powerful voice.

A tall dark blue alicorn stepped forth into the room pointing a daring hoof at her.

"Ah Princess Luna, you think you can stop Sunbutt? Not a chance! My butt will grow and grow until all will bow before it."

Luna flashed her horn and closed her eyes. Luna flew through a dark tunnel toward Celestia’s nightmare.

Atop of an enormous chocolate cake within the middle lay a tiny Celestia, struggling to break free as a giant Celestia with glowing red eyes sat on top of her with a gigantic ass.

"Luna help me! My butt is possessed by some sort of Butt Demon!" she cried out with her hoof reaching out to her.

"All will praise the sun," boomed the giant alicorn above in a deep, demonic voice.

"Luna! You must get out of here! Find all the help you can to stop this monster before everything is--"

"Quiet you!" roared the Butt Demon, adjusting her giant butt over her, thus silencing her.

"Let my sister go!" Luna roared, charging up her horn with a powerful spell.

A lavender ball of pure energy blasted out from her horn to hit giant Celestia in the face, which had no effect on her whatsoever.

"Hah! You cannot stop me Luna!" she mocked, sticking out her tongue. "I am Sunbutt! I can not be stopped! All shall love me and hump my butt forever and ever!"

Reluctantly, Luna opened her eyes, cancelling out the spell. Just in time because Sunbutt had grown to the point that Luna was mere inches from being crushed under her giant expanding ass.

With a sad sigh Luna teleported away, making a tactical retreat.

Ever bigger Sunbutt got, the remaining space within the room being quickly filled by her swelling cheeks. In mere minutes the entire room was filled by giant white pony booty, the walls themselves struggled to contain the colossal rump, which only got bigger and bigger by each passing second.

Dust fell from the ceiling as cracks began to form upon the walls, just before rubble fell down from the ceiling as Celestia’s quickly growing ass began destroying her own castle. The walls groaned before they gave way as her massive rapidly expanding flanks blasted through the walls, leaving dust and rubble in their wake as her giant expanding butt grew out into the city of Canterlot.

Ponies screamed, trotting away in terror as a giant pony ass grew out from the remains of Celestia’s castle.

"I Am The Harbinger Of Your Ascension! Bow In Fear Before Sunbutt Puny Mortals!" boomed Celestia butt in a deafeningly loud voice.

Some brave ponies challenged the giant growing butt, blasting spells and throwing things like rocks at the growing butt. Spells and other objects had no effect on the butt whatsoever.

"Hah! You resist against an inevitability, you are mere dust struggling against cosmic winds before the glory of my big fat pony butt!

"Praise the sun or die! Nothing can stop the Sunbutt!" she boomed, her voice telepathically spoke to them, demanding they shout ‘Praise The Sun’.

Several hundred ponies raised their hooves high into the air, shouting ‘Praise The Sun’. Said ponies were lifted into the air, before being gently placed upon her butt. The moment they landed on her rump, their eyes lit up with love hearts, before they began to hump like crazy against her, along with kissing, rubbing and squeezing her silky soft butt fat, the applied pressure from their hooves slightly compressing down the immense layer of growing fat from her giant butt.

"YES! YES! Worship Sunbutt with your tiny cocks!"

Sunbutt’s butthole shone in golden light, buildings were lifted into the air, before being converted into massive cakes, which were subsequently flown into her giant gaping butthole.

Her gargantuan ass now began to expand faster than ever before, rolling over fleeing ponies beneath the mass of expanding buttfat… yet somehow, those under her butt were not killed, despite millions of tons worth of fat resting on top of them.

In mere minutes, the once great city of Canterlot was gone, replaced by an ever growing butt now expanding into the countryside, levitating up trees, rocks and everything in her path, converting them into cakes, followed by eating them to make herself grow even faster.

Sunbutt rose higher and higher into the air as her cheeks swelled in size, racing across Equestria. The ponies of Cloudsdale could only watch in horror as her butt went ever higher into the air, rapidly approaching them.

Back down on the ground, the ponies of Ponyville gasped in horror as they watched from afar a giant, rapidly growing white mountain of pony butt quickly closing the distance between them.

Princess Twilight Sparkle, Princess Luna, Rainbow Dash, Applejack, Fluttershy, Rarity and Pinkie Pie… and also Spike stood their ground, staring defiantly at Sunbutt.

"Blast her with the elements of harmony! It may be our only chance!" roared Luna, pointing a hood at the giant butt coming toward them."

The elements glowed with golden blinding light…. before being turned into chocolate cakes.

"RUN!" Luna shouted.

With that they turned tail, screaming as they ran into the Everfree Forest.

In mere minutes Ponyville suffered the same fate as Canterlot, buried under trillions of tons worth of giant pony booty. All those who ignored the voice in their head telling to ‘praise the sun’ were smothered in buttfat.

Higher and higher Subutt rose, quickly leaving the planet’s atmosphere into outer space.

"Now, the real expansion begins!" she boomed.

Sunbutt telepathically spoke to every living thing on the planet, calling them to ‘praise the sun’. The several hundred thousand that answered were teleported onto her butt to join in on the orgy of loving her butt.

"The rest of you heretics shall be eaten!" she boomed.

With that Sunbutt wrapped the entire planet in a golden aura, pushing it away from her. Before turning the entire planet and everything on it into a multi flavoured, layered, sphere shaped cake.

The giant butt tore the planet into large chunks, before sending each one into her butthole. Each piece of cakes flying inside her gaping asshole caused her buttcheeks to blast outward in size.

Sunbutt sighed sadly, her butthole still not big enough to swallow planets whole.

Sunbutt flew past the moon at millions of times the speed of light, racing toward the thing that she really wanted to eat… The Sun.

"Get in my belly!" she boomed.

With a blinding flash of light, the entire sun was turned into a giant, sphere shaped lemoncake.

Sunbutt sighed sadly, seeing that the sun was bigger than her.

Sunbutt used her magic to tear the sun into millions of tiny pieces, before aligning them into a straight line. Once in position, she sent the pieces of cake like a conveyor belt into her giant butthole.

Sunbutt moaned lustfully, as the cake flowed into her, her butt expanding in size by thousands of miles a second.

Sunbutt squealed in joy as she became even bigger than the sun, all the while her unbelievably massive cheeks slapped against one another.

With the sun now gone, Sunbutt’s butt turned her attention to the planets of the solar system. With a happy giggle, she turned all the planets and asteroids into cakes, before sucking them all up into her butthole like a vacuum cleaner.

Once done eating everything in the solar system, Sunbutt proceeded to pull millions of nearby rogue planet and asteroids toward her, turning them all into cake, before sending them into the massive black hole that was her asshole.

Sunbutt continued to expand, quickly closing the distance to the nearest star.

In a star system not very far away. Upon the Executor Star Dreadnought, Darth Vader standing before a wide window in the ship’s bridge looked on in horror as he watched a giant white horse butt expand out from the nearby horsehead nebula.

Darth Vader turned to his general Grand Moff Tarkin. "Quickly! Make an alliance with the rebels and get the Death Star ready. For I, do believe the fate of the universe hangs in the balance."

"Yes Lord Vader!" he replied with a salute.

Sunbutt laughed at the pitiful fleet of starships before her, sure it was ‘massive’ in size, but only in number. Their biggest ships might as well be bacteria before the glory of Sunbutt. Even their so called ‘Death Star’ was considered microscopic when compared to the size of Sunbutt’s butt.

Sunbutt expanded rapidly in size to meet them in battle. Once she came in range, they fired their tiny little lasers at her, which did nothing at all, other than grow her butt even faster. The energy from their lasers being converted into buttfat to expand her butt even faster.

Even the ‘biggest’ laser attack from their Death Star did nothing but grow her butt even faster as well.

Sunbutt telepathically spoke to them, demanding they ‘praise the sun or die’.

Sunbutt giggled in joy as thousands of them surrendered before her unstoppable growing butt, by shouting ‘praise the sun’ just as her butt closed in on them. Her new worshipers were safely teleported onto her butt to join in on the never ending orgy.

The rest… were turned into cakes and sent hurtling into her supermassive black hole that was her asshole.

The so called ‘greatest fleet ever assembled’ was completely destroyed in mere minutes. Even those who just used ‘lightspeed’ could not escape when Sunbutt began to expand faster than ever.

"I have enough worshippers! Time to just grow!" she boomed.

Sunbutt’s Buttmaigc had become now so powerful, she was able to pull millions of nearby stars, planets and every living thing into her butthole, sucking them up like a hoover. In mere minutes the entire Milky Way Galaxy was inhaled into her butt.

…. and yet she just kept on growing. By the time she reached the Andromeda Galaxy it was tiny before her. With an evil laugh, she turned the entire galaxy into a massive chocolate cake, which might as well be a cupcake when compared to Sunbutt’s size.

Sunbutt sent the chocolate cake that was once Andromeda into her gigantic asshole, swallowing it down like it was nothing.

The fat within Sunbutt throbbed powerfully, as she grew several times bigger. Galaxy after galaxy was turned into chocolate cake, each one eaten by Sunbutt’s asshole, she only expanded ever faster.

In mere minutes Sunbutt was able to eat trillions of galaxies at the same time.

"The universe is mine! Soon there shall only be Sunbutt!"

Sunbutt’s expansion speed now was traveling at trillions of times the speed of light, rapidly reaching the outer rim of the universe into the great never ending darkness beyond.

Not a single star shone in the universe as Sunbutt expanded out into empty dark space, devoid of anything butt asteroids and rogue planets for her to turn into tiny cakes for her asshole to eat.

… but then eventually Sunbutt hit into what appeared to be an invisible barrier.

"No! I must keep expanding!" she shouted in panic.

Regardless Sunbutt continued to expand, the soft fat of her indescribably large flanks being compressed back as they pushed against the invisible wall.

"You can’t hold me universe!" she boomed.

A moment later, the barrier shattered like glass as Sunbutt exploded out into the vastness of the multiverse itself. All around her there was a sea of countless transparent spheres in a dark void of nothing between each universe. Each sphere was filled with stars, planets and everything that makes up a universe.

The immense fat of her butt was so compressed it was already dozens of times bigger than any of the parallel universes, her flanks were folding around nearby spheres, smothering them in buttfat.

"Now even the multiverse shall fall before Sunbutt!"

With that Sunbutt turned entire universes into massive chocolate cakes, followed by sending them into her butthole.

Even now Sunbutt continued to expand in size, faster and faster. In mere minutes the spheres containing universes were mere mist before her.

Sunbutt laughed maniacally, seeing that she has grown trillions of times bigger than any universe.

However, as the hours went by her laughter slowly died down as the multiverse seemed to go on and on without end.

Sunbutt groaned in frustration. No matter how big she got the multiverse never seemed to come to an end, even as she swallowed quadrillions of universes by each passing second, only more and more universes would pop into existence before her.

"No! Curse you multiverse! You can’t be bigger than me for long!" she roared.

"You have destroyed enough universes! Time to end this." bellowed a deep voice out from nowhere.

"Who are you?!" she roared.

"I am OP Guy and I’ve had enough of your shit!"

With that Sunbutt’s butt began to rapidly shrink in size as the universes she swallowed blasted out from her asshole.

"Nooooooo!" screamed Sunbutt in horror.

Sunbutt became smaller and smaller by greater and greater speed, crying out in anguish over her fate.

Sunbutt screamed as Celestia’s butt shrank back down to its normal size, before Sunbutt was ejected out from Celestia’s ass.

Sunbutt was now a tiny little white butt no bigger than a basketball.

"No! This can’t be!" Sunbutt shouted in denial of her small size.

Celestia jumped out of bed, glaring daggers down upon Sunbutt.

"For the crimes you have committed on all life. I hereby sentence you to be banished into the worst possible universe imaginable."

"You can’t mean--"

"Yes. I’m sending you into the Justin Bieber Universe, a universe where everyone is Justin Bieber. May you forever be tormented by his horrible music," she roared with her horn a lit with golden light.

"Noooooooooooooo!" she screamed, before disappearing in a blinding flash of light into a universe of unspeakable horror and pain… the Justin Bieber Universe.

And so everything that Sunbutt had done was undone thanks to the mysterious, overpowered being known as simply OP GUY.
