The sun's rays shone through a circular window hanging in the middle of a ceiling in a huge, white marble throne room. This room was nicely decorated with mannequins of armour, of both human and pony. In the middle of the room there was a beautifully decorated carpet, following this carpet northwoods you would eventually meet two large stallions, standing side by side before a massive, golden throne. These stallions stood at least eight feet tall, and were clad in heavy black power armour, the symbol of a yellow sun was upon their chests. They were armed with huge swords, that seemed to be a cross between a sword and a chainsaw.
If one followed the sun's rays, they would find them landing upon another sun tattoo marking of some sort. This sun tattoo belonged to a massive, snowy white alicorn, who stood at least fifty feet tall. Each cheek of her rump alone was the size of at least three african elephants. Her legs were as thick as oak tree trunks. This pony was Princess Celestia, the pony with the biggest and fattest pony butt in all of the world and perhaps beyond.
Her eyes were closed deep in meditation. Her meditation allowed her to use her powerful far seeing sight. All seemed well on her world. She peered further outward, beyond her solar system. The other alien races of her galaxy seemed to be up to nothing much and her colony worlds seemed safe from attack.
However, one of her closest alien friends seemed to be in a great deal of trouble. An ominous, massive pink sphere had appeared on their world. And worse still, it was slowly growing.
Celestia prepared herself for battle, powering up her horn with blinding golden light. Her body began to swell upward, her rump in particular began to bloat outward like an inflating balloon, becoming disproportionate in size when compared to the rest of her body.
Her golden regalia began to crack under the increasing pressure of her expanding form. They soon exploded, flying off her body, falling to the floor to be crushed under her mighty hooves.
The guards trotted out to escape their growing monarch. Celestia’s rump soon became so fat it began to push against the very walls of her throne room, the squishy soft fat of her ass conceding deeply from the applied pressure.
In order to accommodate the expanding form of Celestia the walls themselves began to expand as well, and the ceiling above began to stretch further and further upward.
Princess Celestia grew and grew, soon assuming the size of her own castle confined into her throne room. The weight of her body rapidly increased, as her mighty hooves began to sink into the hard marble as if it were made of butter.
Celestia unleashed a loud moan as her horn unleashed a massive explosion of magical energy. Her great and meaty marehood released a blast of cum onto her throne, covering it in her creamy essence, and she skyrocketed into the air, far outpacing the expansion of her throne room.
Celestia exploded out of her castle, destroying it into a million pieces. Like tidal waves, her rump’s cheeks raced across Equestria, flattening all in their path like pancakes from under the immense weight of her ass.
Soon all of Equestria was covered in Celestia's almighty rump, a massive crater was formed in the planet. Nonetheless, her subjects were spared and not turned into bloody paste. Her subjects under her worshipped her almighty butt, by kissing, rubbing, squeezing and thrusting their bodies against her omnipotent rump.
“Oh my.” she said, blushing profusely, a hoof coming to her mouth.
Celestia made to stand up, the shadow of her massive ass casting a dark shadow over the world. The damaged land began to rapidly repair itself from the destruction of her ass had brought.
Her subject cried out in anguish from the absence of her rump’s comfort upon them.
“Sorry, my faithful. Butt I must use my butt to save another great butt loving species.
WIth that she disappeared with a blinding flash of light,.
Elsewhere a lesser Princess Celestia was sat on a small golden throne, with an inferior backside that was only the size of a beach ball each. She stood at a mere six feet tall. This Princess was bony thin and hideously ugly when compared to her much greater counterpart. And her royal guard only stood at least four feet tall, and were armed with primitive spears and thin armor.
There came a loud bang as the golden doors to her throne room slammed open and one of her puny Royal Guards rushed in.
“What is the meaning of this?” she shouted with a sour voice that was nowhere near as comforting as her greater counterpart.
“Your giant ass is in the sky.” he shouted in panic.
“What?!” she roared.” I will destroy you for your insolence!” she said, glowing her horn with deadly magic.
Fortunately, before she could kill him there came a deafeningly loud bang from above. The shockwave from the bang was so intense that dust and debris began to fall from the ceiling.
Celestia flashed her horn, teleporting herself to the roof of her castle to see… a white giant ass of her likeness covering the transparent pink barrier in the sky above. Already cracks were beginning to form upon the primary mobile.
“No! You will not stop me! I will convert all of humanity into ponies!” she flashed her horn, repairing the cracks.
The moment she stopped her spell, the cracks reformed, only much larger this time. Not wishing to risk her barrier’s destruction she maintained her spell this time with a steady flow of magic.
Unfortunately, this merely slowed it down, as she found it harder and harder to keep up with the increasing power of the ass. Maintaining her repair spell she cast a secondary spell to observe her situation.
To her horror, she saw a planet sized rump pressing down on her barrier, each cheek alone was the size of Earth, and still growing at a rapid speed. And she saw the titaness form of herself, who was at least the size of about ten Earths.
“Uhh… I need to get out of here.”
As if sensing her plan to escape the Celestia above literally went supernova in growth. The barrier instantly shattered like glass, and the massive rump of Celestia came crashing down upon her. Her castle and land was obliterated from the power of her rump.
Celestia struggled against the massive butt atop her. Butt her efforts were futile against the power of the butt. It only resulted in her hooves sinking in deeply into the thick, soft fat of her ass. It only became heavier and heavier as time went by. Even her mighty alicorn strength could not help her.
For the first time in her long life, she felt mortal. Whatever this Celestia was she could not hold a candle to her power. She saw her subjects turn on her and worship her greater counterpart. Even the vile humans joined in on the action.
With a deep sigh, she joined in on the action as well in the hope that she could be spared. This Princess Celestia was a true goddess, and she was bony thin and ugly when compared to her.
