Under Her Throne

Court was beginning to gather in the council room as I sat upon Celestia's solid white marble throne. The room was filled with the sounds of nobles filtering in through the massive golden doors to the council room. Various multi-coloured ponies approached the chairs surrounding the huge wooden meeting table. Sitting down at their seats while I sat on the throne. Celestia herself stood in front of me, her body hunched down for some reason.

Celestia's ass was mere inches away from touching my face. The massive pillow-like white ass cheeks jiggled back and forth as she stood above me. I couldn't really see anything else but her rump. I got a strong musky scent from her royal nethers. The smell flew into my nostrils and caused my cock to throb in response. The musk coming from her overpowered anything else in the room.

I soon got the answer to my question as to why she was hunched over when she began to rapidly grow in size in front of me. Her fattening ass pushed against my face as it inflated like hot air balloons. Bigger and bigger, fatter and fatter, her rump became, soon blocking the rest of the throne room from view. I could only see through several small pinpricks of which her butt hadn't covered.

Mid-growth, my hands grasped her fattening cheeks; they sank deeply into the plush bubbly fat of her ballooning ass. Whatever muscle Celestia had it was quickly drowned out by the extra padding of fat plumping into her ass. Making it so I couldn't barely feel anything but her massive rump, which started to surround me. I continued to sniff the air and enjoyed the taste of Celestia's vagina. The scent of sunny d made it so I could barely breathe. The rump of Celestia was like two mountains above me that were growing like dough in an oven.

I soon began to worry; Celestia didn't seem to be stopping her growth. Her rump was so massive now it might as well be a bean bag chair, and it was still getting bigger. Her backside jiggles violently and shakes the whole throne with each movement it makes. It was like a tsunami from an underwater earthquake. The wind her butt was making only forced me to breathe in her musk even more.

"Mmm! You will be punished with even more ass!" she moaned. Saying it to me very quietly as she continued to converse with the ponies around the table. She does her best to keep her poker face so the nobles don't look at her weirdly. The nobles aired out many grievances they had, with Celestia doing her best to help them.

Her ass inflated in size through a massive growth spurt at my insolence. I groaned as her ass pushed me back against the throne, as it came to hit me like a car's airbag, forcing me deeper and deeper into the throne, making it so I couldn't move. I was entirely covered by her massive rump, which made it so I would never escape from under the several tons of butt.

I gulped at the sight of the towering snowy white rump looming over me. I didn't expect her to have become so large. If I didn't know any better, I swore each one of her buttcheeks was about the size of a 10-foot-tall beach ball. The massive white alicorn was hunched over; the sheer size of her ass was big enough to block me from the view of the Court proceeding in front of her. I guess Celestia wanted me to secretly have sex with her, but I don't think my cock is large enough for such a massive ass.

With a giggle, the mare dropped her massive ass down on my lap, her asscheeks clapping loudly with meaty slapping sounds. The whole throne shook around me like it was in an earthquake. The weight knocked the wind out of me as I struggled to get back to breathing. My heartbeat quickens as I continue to worship the ass above me. I squirmed beneath the immense weight of her ass bearing down on me; I could feel my cock being sandwiched between the great fat pillows of her buttcheeks, hugging it on both sides, enveloping it in warmth and softness.

Celestia smirked down at me as she continued to endlessly grind against me like waves crashing against a shore. The tsunami of ass crashing into me over and over. The weight was enough to crush me into a paste, but it didn't for some reason. Clearly, the magic around me was holding my body together even under the several tons of rump above me. The posterior of the solar diarch was like a train tunnel to her vaginal cavity which blasted me with a wind that smelled of her musk. I chuckled at the mare above me and moved my hand to her ass. Spanking it hard and causing it to clap and jiggle violently around me.

"Well, it seems someone is quite excited. Don't worry about anypony noticing you. I will keep you safe, my cute human," Celestia says to me softly with sweetness in her voice. Her rump rapidly grew around me and made it so I could reach her cutie marks less and less. Eventually, my hands were ineffective at reaching the muscle within her rump. I then decided to lick her backside and worship it with kisses. The power of the solar diarch rapidly grew from my worship as she moaned softly. Ushering the ponies out of the room as the solar Court finished. Leaving you and the mare above you alone, along with her guards.

"I shall help you enjoy my rump to its fullest. Don't you worry about anything else but my fat rump, my sexy human," the princess said to me while moaning happily. Igniting her horn and filling the room with the warmth of her power. Grabbing your cock, which caused you to moan as it throbbed hard. It drips a bit of pre-down the tip and onto the floor. Celestia then slowly puts your cock into her ass and makes her moan even louder. Starting to bounce up and down on you in earnest. The massive amount of her cheeks shook the whole room and crashed against her throne of hers. Though your cock could not reach the inner depths of the mare due to the size difference.

You blushed and moaned against her rump, but it was drowned out by the constant clapping of her backside. Making you unable to hear anything else but the jiggling of her bottom. Your mouth was dry as you licked your lips, as the area around you was glowing and sparkling with magic. Celestia hummed to herself as she rode your cock with practised ease as it got smaller and smaller compared to her growing body. Spreading out her wings as they start to touch the columns next to her. The mare's body had grown to be the height of a giraffe and with her rump seeping over the sides of the throne and reaching the floor. Slowly creeping along it like a predator stalking its prey.

You tried desperately to hump against her butt though due to the weight of her butt, you could barely make a movement with your hips. Leaving Celestia to do most of the work as you continued to kiss and worship her ass. At this point, the ass of Celestia had fully reached the floor and started to climb up the columns next to her. Going up several feet and, lifting Celestia up above her throne as it lets out a groan before exploding under her weight. Forcing you deep into the floor with an indent of the ass of Celestia on the marble floor of the castle. Several of the guards looked over and grew hard in their armour. Starting to go over and beginning to fuck the ass of Celestia with their much bigger cocks.

The massive balls of the stallion slammed into the rump of Celestia. The ass of Celestia having started to knock over the pillars beside her with huge thuds and booms. Cracking the floor like a massive sinkhole was opening up from her rump. Celestia continues to ceaselessly bounce till your cock falls out of her backside. Being forced to just have a butt job from the soft and warm ass of Celestia. Though you could not compare to the stallions, who stood on the rump of Celestia as it grew under them like a growing tide of dough. "Seems like you can't handle all this rump, silly human. Guess you will just have to watch my sexy guards fuck my growing rump," Celestia says with a lustful tilt to her voice as it booms through the air. Shaking the whole castle and mountain to its core. Having to take on the Canterlot voice to be heard over her rump.

To add insult to injury, you could now feel your cock rapidly becoming smaller. With a whimper humped against Celestia's fattening ass. Inch by inch, your cock shrunk to the point it might as well be only an inch long. Celestia meanwhile moaned as she skyrocketed into the air, a massive flood of fat pumping into her ass, causing her plump bubbly cheeks to clap like thunder. The thunderclap shook all of Canterlot as ponies started to look around. Getting to see where the sound was coming from as they stopped what they were doing. Several stallions blushed heavily as they slowly grew hard at the sound of the asscheeks clapping.

Celestia's Royal Guard began to become stronger; their muscles bulged as they became larger. Their cocks bobbed up and down as they became bigger and stronger. You could see the veins on their muscles bulge as they slowly expand. The guards' whole body sparks with yellow-coloured lightning bolts going across their bodies. Their veins bulge with power as they moan hard and pant heavily. Continuing to thrust in and out of the ass of Celestia as they grew. The guards' own power grew along with their muscles as their armour exploded off of them in metal shards. The metal shards bounced off the ground with clings before stopping inches before the wall.

The massive horn was like a spiralling skyscraper that slowly inched higher and higher into the air. Power sparking off her horn idly and humming with her holy energy. Celestia then winked down at her royal guards and licked her lips. Saying to them with her booming voice. "That is right, my dear guards. Show your princess how devoted you are to her. Don't stop til you release your loads right in my royal rump" Celestia then shakes her massive rump for emphasis, which shakes the whole castle and mountain. Causing avalanches to fall down on the city before melting from the heat coming off Celestia herself. The entire castle started to slowly melt around her.

The solar princess's body glowed as the floor around her started to liquefy. Turning into a massive pile of steaming marble. I was forced to sink into the growing puddle of marble which surrounded me. Though it only felt like a nice hot tub around me. Relaxing my muscles and allowing me to continue thrusting as best I can. Trying desperately to prove that I could please the mare as good as the stallions. The whole castle starts to glow white hot before slowly melting like candle wax as Celestia explodes out of the melted ceiling.

The princess was now able to see across the courtyard of the castle and towards the city. Smiling sweetly at her ponies as the sun behind her shows off how pristine her fur is, even with all the melted castle around her. The guards continued to fuck the ass of the princess as she started to push them into the mountain, as it slowly crumbled behind her. All of Equestria was able to see how the solar diarch was ascending into the sky like a building being erected. The princess giggles as she kicks a half-melted column which falls into the new lake of melted marble with a splash before dissolving entirely. Her wings cast a massive shadow over the city of Canterlot. The feathers in the shadow were like a giant's fingers reaching out towards the city.

Huge masses of white bubbly fat ass flooded through the city like a raging river, flattening buildings in their way. Ponies found themselves smothered under the great pillowy mass of Celestia's ballooning cheeks, looming over them like two twin gargantuan mountains. Celestia's cheeks were perfectly round and smooth, even at their massive size. Even as the ground underneath Celestia began to melt and liquid lava from the sheer heat of her ass, the ponies smothered under her rump were not dissolved by the intense heat. The ground fissured and went upward like a ship that was capsizing before then getting swallowed by the whiteness of Celestia's rump. The lava sea forming around Celestia did nothing but act as a nice bath for the mare. A slightly warm one but a nice bath.

Celestia giggled as she became physically and magically stronger than ever before. Celestia could feel her wing muscles crackling and groaning as they grew and grew within her wings. More and more muscles across her body formed and expanded to fill the ever-growing form of the white alicorn. She breathes, drawing in ancient arcane power that had not been harnessed for millennia. Waves of golden magical energy sparked off her body like raging lightning bolts. Huge fat masses pumped into her asscheeks as if they were nuclear fusion reactors. The twin suns of her cutie marks glowed with a blinding light from the massive amount of magical energy flowing into her body. Her whole body started to glow like the sun in the sky. Blinding all ponies around her with the sheer power she had around her. Little tornados of arcane energy formed around in the air and crackled with heat lightning. She was becoming a sun in our own right.

Celestia used her magic to unblind the ponies around her; she did after wanting them to gaze at and worship her ass. Her magic goes across the body of the ponies around her. Making sure they can see once more as she then smiles even wider. Showing off her pearly white teeth, which sparkle like marble in the sunlight, as she keeps bouncing her cheeks up and down on the ponies. Having covered you and the Guards that were fucking her. Making sure that they keep fucking her as her butt cheeks clap and jiggle violently. Shaking the whole planet more and more. The tectonic plates of the planet started to shiver and groan under the growing weight of Celestia.

The whole world of Equus starts to crack under the massive amount of tons being added to the body of Celestia. The oceans of the world slosh and roll violently over the landscape before hitting the body of the white alicorn. Not doing any damage to any power under her as ponies grab onto her. Trying to hold onto the massive growing mare as Celestia moans loudly. Shaking the whole planet and sending clouds flying around them with her booming voice. Blushing deeply as she spreads her wings and continues grabbing ponies out of the water and putting them on her. The world continues to crumble apart around her like a Faberge egg.

The tectonic plates of the planet go up on their sides and jutting towards the skies. Spewing magma out from under them before being cooled by the juices of Celestia and the ocean around them. The whole climate of the planet changes as Celestia's power grows more and more. Rapidly starting to reach up towards the stratosphere. Her horn jutted out above the skies and pierced through the veil of clouds above the ponies so she could look across the land. Easily able to see creatures struggling and grab them so they don't get harmed. Making sure they stay safe from what is happening. Her horn glowing and staring down at them like a loving goddess. Picking them up with her magic like an angel and allowing them to go into her chest. Allowing them to get comfy in her chest fluff and on her growing rump as they start humping her ass and worshipping her.

Trapped between the supermassive grand canyon-like gap of Princess Celestia's buttcheeks lay her sister Princess Luna. She had made a futile attempt to stop her ascension. Celestia hardly even noticed her attempt to stop her; it was as if she was like a gentle breeze blowing against her when she cast her weak spells to try to stop her. The blasts of her dark purple magic hitting Celestia only fueled her growth more. Adding her own magic to the ever-growing pool of Celestia. Luna groaned under the massive rump of her sister and tried to kick her off. Her hooves only sank into the butt of Celestia, which was like quicksand. Forcing Luna to use all her strength to get her legs out of Celestia's rump. Celestia was annoyed but also slightly impressed with her sister. Being able to lift so many tons of backside, even a little, was a monumental feat equivalent to Atlas lifting the world. Nonetheless, such insolence could not go unpunished. Thus, Celestia, with her magic, began to weaken the mighty alcorn trapped between her buttcheeks.

Luna gasped upon feeling like a pin had been japped into her butt, right upon her crescent moon cutie mark upon her right buttcheek. Her body was glowing a bit with her magic, and it was being slowly slurped out of her by the power of Celestia. Luna tried desperately to stop this from happening but was powerless to stop her fellow monarch. The mare looked on in horror as her rump began to rapidly deflate in size. The backside of Luna let out deflating balloon noises as it slowly shrunk more and more. Getting more and more skin and bones as her butt shrunk with a glow that looked like Celestia's magic. Her body shrunk down in every way; she was literally losing inch after inch in height with each passing second. Her size was siphoned by Celestia like she was a vacuum as Celestia opened her maw and slurped the magic of Luna up like a noodle.

By the end of it, Luna was a tiny little pony about the size of a small house cat with a painfully flat pancake of a rump. To rub salt into the wound, Luna could magically see Celestia's gargantuan ass, with each cheek about the size of a gas giant. The buttcheeks of Celestia jiggled and clapped like massive shaking mountains in an earthquake. The fur of Celestia was like a forest to the poor mare known as Luna. The gigantic solar mare's ass jiggled about wildly like a stormy ocean as monstrous surges of fat pumped into her ass. The magic of Luna and Celestia combined and formed into a bluish-yellow glow as Luna's cutie mark disappeared. Then with a massive flash, the butt of Celestia now had a cutie mark with the sun and moon intertwining. Showing how Celestia had taken all the power of her sibling and taken her role in the world.

Celestia smirked as she then felt her sister shrink down even further under her. The poor former alicorn had her wings stripped from her as she was turned into just a normal unicorn as Celestia absorbed all of the power from poor Luna. Though Luna was still immortal as Celestia was not a cruel goddess as she kept growing bigger and bigger. The rolling rump of Celestia crushed more and more of the planet under its trillions of tons of weight before covering the whole world. Turns it into a white-coloured orb floating in space as Celestia moans and licks her lips. Igniting her horn like a miniature sun before teleworking the planet into her body. Turning it into pure growth fuel while putting the creatures onto her body to worship her.

Celestia spread her wings as she got a wing boner from the amount of pleasure she was in. Moaning loudly enough to cause the very fabric of reality, which stutters like a TV in front of the sheer power of the solar diarch. The lone princess has long outgrown her home planet and uses her rump as the new planet for her precious worshippers. The butt of hers has gotten its own atmosphere as Celestia then flaps her wings, which creates a massive cosmic wind. Forcing several planets out of alignment before Celestia reaches the sun, which glows in front of her. The princess then ignites her horn again and creates a spoon. Starting to eat the sun as her growth goes into overdrive as her body flashes and grows in massive spurts. Rapidly doubling and then tripling her previous size in mere moments as she slurps down the hot plasma of the sun like it was a soup with her massive silver spoon.

The massive spoon causes the roiling ball of plasma to spark and send off a solar flare into the mare above it. Celestia is just absorbing the power from the solar flares, which hit her fur and dissipate around her. Eventually, she finishes swallowing the sun and having it all within her tummy. Her belly gurgled and sloshed loudly to shake the whole solar system. Power sparks around the body of Celestia as her eyes start to glow white hot along with her cutie mark. The princess then spreads her wings, and she lets out a reality-shaking moan as she grows. Her back slams into Jupiter before she grabs it with her magic. Her horn glows and holds the remains of the planets of the solar system. Slurping it all down as she fills the whole solar system with her massive body.

The human and Luna, who were still under her, are trying to worship the ass of Celestia. Celestia giggles as her nerves spark in her body which makes her shiver violently. Causing shockwaves across the cosmos as Celestia turns her mouth into a vacuum. Her belly is like Kirby's as she starts swallowing more and more of the universe around her. Rapidly growing bigger and bigger as her body exploded in growth. Her eyes glow with a fire behind them as she eats everything she can. Even chewing the spoon she created and swallowing the pieces with ease. Turned everything she could into more growth fuel but grabbed the sentient creatures and put them on her ass, with each cheek being the size of a supermassive black hole at this point.

Celestia smirks to herself and then flaps her wings again. Making her way across hundreds of thousands of light-years before reaching the centre of the universe. Stars and planets fly by like lights on a street at night before they are absorbed by her maw. Celestia then grabs the supermassive black hole in front of her like a massive sandwich before shoving her maw into it. Slurping it up like spaghetti as the supermassive black hole expands around her. Covering her as it struggles against the force of its own gravity. Causing more and more of the galaxy to go into the maw of Celestia as she eats it from the inside. Like a growing baby in the womb, Celestia starts to poke against the edges of the black hole.

With a massive explosion of white light, Celestia explodes out of the black. Sending massive pulsars flying across the universe as Celestia rapidly grows like a supernova going off. Glowing white hot as white lightning sparks across her body. Eventually, forcing the human and Luna against the boundaries of the observable universe. The very fabric which held it together started to crack like glass as Celestia continued to grow, saying down to her human companion with her newly gained telepathy. "Hope you are enjoying the view, my lovely human. I am only going to keep getting bigger and bigger. I will never stop growing for you." Celestia says with a loud moan as she orgasms hard. Her legs finally shattered out of the universe and into a white void around her. It is like a baby chicken breaking out of an egg as she breaks out of the top with her head before her legs explode out of the body. Sending pieces of it flying through the white void with more universes flying around.

The solar diarchy grabs the universes around her and starts juggling them in her hooves. Bouncing them up and down like hacky sacks. Eventually, they land in her mouth while moaning to herself. Chewing down on them like they are chocolates and swallowing the pieces of the universe as her body grows more and more. The white alicorn explodes in growth as she puts the universes in a line in front of her. Covering them with her magic and taking the sentient beings out there on her rump with the others. Allowing them to join her ever-growing pool of worshippers as her growth is seemingly endless. Celestia eats the universe eggs and slurps down the liquid within the glass-like containers. Throwing the empty glass-like containers and throwing them on the ground. The void slowly grows with more and more broken shards of empty universes. Eventually, all the universes are consumed, and all that is left is an empty void. Leaving Celestia floating in a void, and she says to her human lover. Allowing him to see her massive hills of rumps with her magic. "Let me use my power so that you can look at my gorgeous rump. It is the most perfect thing that you will see. Keep worshipping my rump like a good human, and maybe I will allow you to fuck my butt."

The human starts to rapidly hump the butt of the massive alicorn above him with his cock. His balls slammed into the butt of the solar princess. Causing massive jiggling tidal waves across her multi-universal-sized butt cheeks, which shakes the fabric of reality around them. The human could not hold out long due to how sexy the mare above him was. He says to the pony above him with a moan. "I'm gonna cum, my lovely mare. You are so good to all your subjects. Love you so much, Celestia". Celestia then flashes with power and lets out a loud moan. Her eyes go into the back of her head as she rapidly grows bigger and bigger. Crushing the remains of the universes under her butt as the fabric of reality cracks under her. Eventually, with a massive boom and crash, Celestia then slowly opens her eyes to a light blue light touching her eyes.

"Sister, we were worried about thee. We were wondering why thou had not woken up yet. We are just glad you are awake now," Luna says to her sister with a smile as she steps back. Celestia yawned and smirked happily as her sister jumped up. Landing on the ground with a thud and smiling at her younger sister. "Sorry, my dear Luna. I just had a really nice dream". The now omnipotent goddess says with a smirk on her face. Feeling her body start to slowly grow to start the cycle over and over. This was gonna be quite the fun experience to have for the rest of eternity. She thought to herself before going out to do her duties with her sister walking close behind her.

Under Her Throne.
