Twilight Wants A Big Fat Butt Like Princess Celestia's Butt
Late on a wondrous lavender night there was a massive, towering, beautiful alabaster alicorn known as Princess Celestia lying fast asleep in her huge, red love heart shaped, queen sized bed. A silky soft white blanket with a large spiraling sun like her cutie mark was lay over her.
Princess Celestia had the finest, biggest and fattest butt in all the world. Her enormous, plump, smooth, round, fat ass was so massive and beautiful beyond compare to any other butt. None of the other lesser mares with their smaller, inferior butts could ever hope to compare to this alicorn's glorious butt of butts. Every stallion cried out her name when they rutted a smaller lesser butt.
In her sleep the mare of divine butty was smiling broadly. A moment later she uttered a most sensual moaned as she licked her lips, due to having a particularly good dream.
"Mmm! Cake!" she mumbled in her sleep.
All of a sudden, there was a loud knocking on her door. "Get up Celestia! It's me Princess Twilight' Sparkle," shouted her muffled voice from outside the hall.
Celestia groaned in annoyance, before she spoke grumpily. "Twilight, can't it wait until tomorrow?"
"No! This is really important!" she shouted with anger in her voice.
"OK! Fine! I'm getting up!" Celestia groaned before she stumbled out of bed to slowly make her way to the door. "This better be important."
Celestia opened the wooden door to see Twilight's sad face, her eyes badly bloodshot.
"Oh Twilight, are you OK?" she spoke in a soft voice.
Twilight wailed in grief. Less than a second later Celestia lunged forward to gently wrapped her hooves around her.
"Oh Celestia, it’s just awful," she cried out in anguish as fresh tears streamed down her cheeks.
"Let it all out Twilight," she said softly as she leaned her head down to give her a reassuring nuzzle.
"I-I--" she spoke briefly before she once again began to wail in grief.
Without a word Celestia carried the smaller distraught alicorn to her bed.
Once there she lay herself down on her side with Twilight gently held in her hooves, before she leaned her long swan like neck down in order to begin nuzzling her affectionately. Shortly followed by folding her wings over her, the soft touch of her wings enhanced the experience of this cuddle even more.
"Shh, my little pony," she whispered in a soft, soothing voice into Twilight's ear.
Several minutes passed with Celestia merely holding the grieving smaller alicorn with her silky soft body.
Eventually, Twilight calmed down a little. Slowly, the smaller alicorn lifted her head to look up at Celestia with her huge, purple, badly bloodshot, moist eyes. Celestia’s huge magenta eyes stared into Twilight’s with a look of utmost concern and compassion.
"Oh Celestia, I want a beautiful big fat butt like yours," she spoke in a low, broken voice.
"Oh Twilight, your butt is already a beautiful big fat butt," she said softly as she gave her rump a tight squeeze with her hoof, digging deep into the soft fat of her smaller behind.
"But… but…. but…. but… my butt isn’t nearly as plump and massive like your glorious big fat butt!" she spoke in a raised voice.
"You must be patient Twilight. You are an immortal alicorn now, one day you will grow to be just as big as me, thus you will possess a big fat butt just like mine," she said as she roamed her hooves all over her smaller butt.
Twilight began wailing in grief again. However, this time Celestia leaned her head forward to bring Twilight into a deep passionate kiss. The larger white alicorn’s tongue gently caressed the purple alicorn smaller tongue, swirling around it in a tender display of affection.
Twilight moaned in pure bliss as she raised her hooves in order to wrap them around Celestia’s massive rump, digging deep into the soft fat of her enormous butt, giving it the odd squeeze here and there.
For the next several minutes, Celestia and Twilight’s fondled each other’s butts with their hooves, giving their butts a tight squeeze here and there in order to dig into the silky soft flesh of their rumps. Every time they squeezed their butts both Twilight and Celestia cry out in pleasure as their marehoods leaked out liquid onto the bed due to the amazing feeling of their butt getting massaged by their silky soft hooves.
Eventually, they slowly parted lips. However, Twilight still seemed upset.
"Celestia, I want a big fat butt like yours now," she said as she looked up at her with pleading doggy eyes.
Celestia sighed. "Very well, Twilight," she said as her horn lit up in a golden aura.
There was a blinding flash of light. When Twilight opened her eyes she had found herself sat on a fancy red arm chair before a large white marble table. On the table before her was a huge, towering, most delicious chocolate cake on a white plate. Standing beside her was Celestia, who looked down at her with a warm smile.
"A cake? This is how I’m going to get a big fat butt like yours?" she said with a most bewildered look on her face.
"THIS ISN’T JUST ANY CAKE! THIS IS THE MAGICAL CAKE OF BUTT FATTENING!" she boomed dramatically in the traditional royal canterlot voice.
Twilight Sparkle gasped in shock. "So the legends are true! The real reason Princess Luna had become Nightmare Moon was because she could not finish the cake?"
Celestia sighed sadly, a single tear fell down her cheek. "Yes, Luna could not finish the cake. After eating about three quarters of the cake she became full. Thus the Cake of Butt Fattening became angry with her and teleported away."
Tears began to form in her eyes as she continued. "Shortly after my sister became enraged that her butt could not compare to mine. I tried to reason with her, by telling her that her butt was beautiful and only a little less bigger and fatter than mine. But she wouldn't listen, thus soon after the evil spirit of Nightmare Moon took control over her and you know the rest."
Twilight had tears in her eyes as she listened to her tragic tale.
Celestia turned to Twilight to look deeply into her eyes. "I implore you Twilight, if you are to eat this cake to acquire a big fat butt like mine. You must eat every single crumb of it!" she shouted as she stomped her hoof on the floor, which caused a massive crack to form upon said floor, due to her super alicorn strength.
Twilight saluted with a look of determination in her eyes. "You can count on me Princess Celestia!"
"Before you do, I must inform you that you have to eat the Cake of Butt Fattening like a filthy slob."
Twilight Sparkle nodded. With that she flapped her wings to fly off high into the air, before she dived upon the massive chocolate cake. As a result huge chunks of cake splattered everywhere. Like a pig she sloppily ate the delicious cake without care as her fur became badly stained with chocolate and cream.
Twilight with steely resolve devoured the creamy, chocolatey sweet taste of the delicious cake. Drool began to flow out from her muzzle as she feasted upon the exquisite chocolatey goodness of the cake. Sweet tasting chocolate tickled her taste buds as she began to moan lustfully as she ate the yummy chocolate cake.
Soon tears of joy began to fall down Twilight cheeks as she noticed her body and butt had begun to swell slowly bigger and bigger as she ate the delectable cake.
The chocolate cake rapidly became smaller and smaller as Twilight continued to inhale the cake into her muzzle. However, just as she had finished three quarters of cake she cried out in agony as tears fell down her cheeks, whilst her stomach throbbed painfully from the mass of cake inside it.
Celestia gasped in horror. "Come on Twilight! Eat the whole cake! I believe in you!" she shouted in encouragement.
Twilight roared as she slammed her head into the chocolate cake, ignoring the painful protests of her belly. The cake began to rapidly wither away as she ate it, until there was only a single crumb left.
At this point the mass of cake inside her had become too much, thus she fell onto the table.
"Go on Twilight, it’s the last crumb," screamed Celestia in panic.
Twilight groaned as she weakly stuck out her tongue to lightly lick the crumb in front of her. However, soon a look of rage crossed her face as she shook her head, followed by slamming her head down upon the last crumb of cake.
She swallowed, before her body became quite a bit bigger as the last crumb fell down into her stomach.
Sweating and panting out of breath Twilight slowly turned her head to look upon Celestia, who had tears of joy in her eyes.
"You did it Twilight! You ate the entire Cake of Butt Fattening," she said in an awestruck voice.
With trembling hooves Twilight stood back on all fours. Her body now just as tall as Celestia. She turned her now long swan like neck to look upon her massive butt, just as big and fat as Celestia’s butt.
"Yes! Yes! Yes! Yes! Yes! Yes! Yes! Yes! Yes! Yes! Yes! Yes! I now got a big fat butt just like you!" she screamed in happiness as she looked upon her massive butt with her eyes sparkling in joy.
Celestia stood on the table to embrace her now equal sized alicorn.
"Now along side me, all the stallions shall cry out your name as they fuck a smaller mare’s butt. And so will humanity!" she boomed in a loud voice.
"Oh, I can’t wait until there’s another handsome human in Equestria!" she shouted excitedly.
"I’ll teach you some magic to make their penises bigger. It makes all the human on pony buttsex all the better," she said sensually as a nasty grin formed on her face.
"Oh, can we have a threesome with him?!" she shouted, before giggling excitedly.
"That we will," she said as she looked at her with bedroom eyes.
With that the two came together to wrap their hooves around each other as they tongue kissed one another passionately, moaning lustfully.
Just then there was a blinding flash of light followed by the appearance of the dashing human male known as Commander Shepard in his black N7 power armour between them.
"Hello there sexy pony ladies," he said sensually as he gave them bedroom eyes.
Twilight and Celestia squealed excitedly before they dived on top of him and smothered him in kisses as they moaned sensually.
