Sunny

Today was a most joyous day, like most days under Princess Celestia's magnificent sun. Her glorious majesty, the big white horse herself was sat at a fine dining table in her castle. Her mighty form towered over her little sister known as Princess Luna sitting next to her.

To befit Celestia's glory, she had a huge pile of pancakes piled upon a plate in front of her, they were smothered in chocolate and sweet whipped cream, truly a worthy meal for this mighty alicorn. Luna on the other hand was merely eating a bowl of porridge, laced with some plain greek yogurt and blueberries.

Celestia, despite the fact that she was a princess dove her head into the pancakes, eating them sloppily like a filthy commoner, smearing her face in chocolate and cream. She moaned at the taste of the pancakes.

“Mmmmmmm!” she moaned.

Unfortunately, as the last pancake fell down into her tummy there came a loud rumbling sound.

“Huh?” she said in a most worried tone.

“Grrruullll!” her belly growled.

Celestia’s eyes widen in alarm upon seeing herself rapidly looming higher into the air, the features of her body bloating outward along with it. She craned her neck back to see that her rump in particular was cartoonishly growing in size, the size of two inflatable beach balls now, and still growing.

Her thighs rapidly thickened, her legs swelling in thickness to help support her rapidly-swelling rear end. The growth indeed was at its strongest in her backside, becoming quite disproportionate to the rest of her body.

Her hips became monstrously large, only growing bigger and bigger by the second – the sight of them growing in size along side her ass made her look absolutely breathtaking. Celestia’s cheeks jiggled like crazy as more and more flesh was pumped into her glorious big white bubble butt.

Celestia gave a cry of pain, as her horseshoes began to become uncomfortably tight.

Suddenly, the wooden chair in which Celestia’s great backside sat gave a loud creek, before snapping like matchsticks beneath her.

There then came a loud crash as the mighty fat rump of Celestia slammed down upon the floor, turning what was left of the chair beneath her into sawdust. Soon after, Celestia’s golden regalia and horseshoes blasted off her like a shotgun, shattering into tiny pieces.

Celestia now assumed the size of a mighty shire horse. But even then the growth was not stopping, her body only became bigger and bigger, fatter and fatter, heavier and heavier, taller and taller, wider and wider.

“Sister! What’s happening?!” shouted Luna, backing away from the growing Celestia.

Celestia was about to speak, but she was cut off as a huge growth spurt flowed through her, her massive body casting a dark shadow over Luna as she now became as big as an african elephant, her rump rippling like jello as fat was pumped into it.

The jiggling of her cheeks intensified dramatically with the explosive growth. Her cheeks wobbled widely, frequently slapping the other cheek with a delightful sound of flesh slapping against flesh.

A memory, from a thousand years ago entered her mind. An old, grey stallion lay on his deathbed.

“Celestia, you can’t hold back the fat forever, so stop eating so much fattening food, for sooner or later that ass is gonna blow, and when it does, I just pray you're not in the same room of someone you love.”

“Uhhhmhmmmmaaahhhaa!” mumbled Celestia's past self with a mouthful of cake, swallowing it down before speaking properly. “Such nonsense dietitian. I don't know why Luna even hired you. I’m an immortal alicorn, and I’ll eat even more fattening food just to spite you.”

In the present there came a… whisper of the dietitian’s voice… from beyond the grave into her mind. “Told you.”

“Luna! You have to get out of here! Save as many ponies as you can!” Celestia shouted.

“But, Celestia… surely…--

Luna screamed as Celestia's suddenly skyrocketed in growth, the growing tide of fat from her gigantic backside sending her flying into the air with a mighty slap of her massive right buttcheek into the marble walls on the other side of the room.

Celestia's cheeks now assumed the size of an African elephant... each. Her head reaching the height of a giraffe, nearly touching the ceiling above.

“Luna!” Celestia screamed in panic.

Luna quickly recovered, she shook her head, before jumping to her four hooves.

“We are not leaving thee!”

“You must! My fat has reached critical mass, my fat suppression spell no longer works. I can't hold back the tide any longer”

“But…---”

Celestia was about to say something, but another growth spurt saw to her head going through the ceiling.

Luna looked on in fear at the sight of her sister's cheeks ballooning ever outward, her flanks began to press against the very walls, the squishy soft flesh of her rump being pushed back deeply as they pressed against the walls. The room creaked and groaned from under the weight and pressure of her growing body, cracks formed along the floor, dust and debris fell from the ceiling.

“Okay, we shall go.” she said nervously.

With that, Luna trotted out, from there she quickly made her way down the hallway, columns falling from all around her. Castle servants and Royal Guard were screaming in terror, many of which were running around in circles like idiots.

Fortunately, Luna with her mighty alicorn magic wrapped droves of them in an azure glow, dragging them along the floor with her as she trotted out the castle’s front door.

Luna jumped high into the air, roughly tossing the castle staff into a nearby swimming pool, as to not kill them, before landing in the crowded streets of Canterlot with a bang.

In the city, many ponies stared in fear at the sight of the castle falling apart. The castle staff and Royal Guard in the swimming pool quickly scrambled out of the water, before fleeing into the city.

“Fly, you fools!” screamed Luna, trotting toward the city gate.

The crowd was about to question her when suddenly the castle exploded, shattering into smithereens as a titan white horse rose like a mountain in its place.

“Run! Everypony!” screamed Celestia.

As their Princess commanded, they ran for their lives in a very disorganised fashion, screaming in terror and tripping over each other, running over fallen ponies in a frenzied rush to get away.

Celestia looked on in horror below, watching has her growing buttcheeks bulldozed surrounding buildings, flattening them like pancakes beneath them.

Celestia tried to stand up and fly away, but it was no use. She was simply too heavy.

She sighed in relief, seeing that her growth was slow enough for them to get away.

Alas, Celestia's cutie marks began to glow with blinding light for a brief moment, before a massive growth spurt that saw her head reached towards the clouds in an instant, and flatten the entire city beneath her under the mass of her alicorn butt fat.

Tears began to swell in Celestia’s eyes, before she buried her hooves into her face and began to wail in grief, a river of tears flowing down her cheeks as she continued to grow.

Celestia’s cries of despair filled the air, as her cheeks rolled across the countryside, flattening everything in its path. Pegasus ponies picked up their non flying friends to safety, looking on in sadness as Celestia’s tide of fat destroyed everything in sight.

Celestia grew… and grew…. Until her head was in outer space… and her rump had literally covered all of Equestria under her fat.

Celestia with bloodshot eyes stared down at the planet below, looking in despair over what she has done.

“It’s all my fault. If only I had listened to my dietitian.” she said in a low voice.

Celestia buried her face into her hooves, wailing in grief over the loss of life. She continued to cry, until she felt something odd.

“Huh?” she said in confusion.

She focused her senses, stopping her crying. She could feel something odd, a ‘prodding’ feeling.

With a flash of her horn, she cast a spell, scanning her rump for her subjects to find they were in perfect condition, despite the fact they were smothered under her rump’s incredible weight, and somehow still maintained the ability to breathe. Her rump did indeed destroy everything, but every living thing was spared.

She blushed at the sight of her subjects in an animalistic frenzy of kissing, licking, rubbing, squeezing, and humping her rump’s soft flesh. Her subjects were in a state of utmost bliss, the weight and the softness of her massive rump felt absolutely incredible.

Those at the edges of her rump’s horizon latched themselves onto it, and began to hump against it, groaning and moaning in ecstasy at the amazing softness of it. Despite how insignificant their penises were she could still feel them, she could feel them as if she was normal sized.

A devilish grin formed on her face, before she decided to move her hips back and forth, grinding her massive rump against their small forms. She smiled at hearing them moan aloud into the mass of squishy white flesh smothering them.

Her soft, heavy rump massaged their tiny bodies. Her subjects moaned in bliss at the soft feel of her giant squishy ass rubbing back and forth against them. Celestia for her part moaned at the feeling, in all her long life, she never felt such passion from so many lovers at once.

Many of her subjects soon succumbed to the amazing feel of her rump, unleashing their creamy white essence upon her fat milky white cheeks. Upon the cum touching her rump Celestia's cutie marks had glowed with power.

Celestia opened her mouth wide and began to moan aloud as the growth flowed through her, her rump rolling across the planet, smothering everything in its path. In mere seconds her rump covered the entire upper part of the planet, continuing from there to expand out into space.

Vast oceans worths of marecum blasted out of her vagina, covering the entire planet in her delicious sweet whipped cream flavoured essence. Her subjects and her newfound subjects drinking the cum, moaning at its delicious taste.

Soon, the canyon of her backside grew so large it began to encircle the planet, entrapping the entire planet between her absolutely gargantuan cheeks, squeezing all living things within the softness of her rump. Every living thing on said planet humping her rump in abandonment and in general adoring her rump with praise.

“Oh... my.” said Celestia, blushing profusely with a hoof over her mouth at the sight of her now massive, gas giant size.

Suddenly, a small, dark blue blur came flying toward her from the planet below. Celestia smiled, seeing that it was her sister.

Luna flew toward her, gracefully landing on Celestia's nose, meeting Celestia’s massive magenta eyes staring down at her.

“Sister! I’m so glad you’re Okay!” she shouted.

Luna cringed at just how loud her sister had become.

“Sister, you need to go on a diet.” Luna shouted.

There came a flash, followed by the appearance of Discord next to Luna.

“No! She's so sexy as a gigantic hippopotamus!” Discord protested.

Celestia growled angrily.

“Discord… I need to lose weight. How am I supposed to rule a kingdom being this big?”

“Why rule just this kingdom? Why not more! Your magical power is in your butt! The bigger it is, the more powerful you become!”

“Sorry Discord, I’m going on a diet. I need to shrink down.”

“Nooooooooo!” he screamed. “You’ll ruin that big sexy booty and turn into a bony thin mare!”

The End
