Late one evening, after a long and boring day at the office you were home. At long last the tedious grind of work was finally over. All you needed was to get rid of your pesky work clothes so you could masturbate.
A broad smile was on your face as you turned the keys to open the front door. You were so excited to jerk off that you did not hear rave like music playing inside your house. Once you opened the door.. your jaw dropped.
Right in front of you was a beautiful alabaster pony creature, who was dancing. Her massive white bubble butt shook from side to side… you were unable to speak as you simply stared with wide eyes at her amazing ass. An ass you knew all too well.
That ass belonged to Princess Celestia, mortal men were not meant to witness such beauty.
"Oh… my," you simply said in awe.
The huge butt before you jiggled from side to side as she danced. It was hypnotic, some drool began to drip down your face as you continued to ogle her ass.
With a small flash of golden light from the tip of her horn the door had gently closed behind you.
"Hey there, handsome," she said sensually as she looked back at you with bedroom eyes. "Like what you see?"
You nodded nervously. You and no one else paid any attention to a white mass from high above that slowly descended from the ceiling.
"Oh, don’t be shy Anon. How about me and you go upstairs and--
"No! My butt is superior! So, he’s going up stairs with me first!" shouted another Celestia, who wore skin tight, black leather.
"Arghhhhh! Me booty be superior! The handsome landlubber be invited to me ship! We’ll drink the finest rum together before I shall share my booty with him!" shouted a stereotypical pirate Celestia with a mighty grey beard, who wore a black pirate hat with a skull on it and a black eyepatch on her left eye.
All manner of Celestia began to approach you. Some of them were even robots.
"No! My butt is superior! He will-- spoke another Celestia with a steel saucepan on her head-- who you could no longer hear, due to the sound of a massive pair of white hooves landing next to you… she hit the ground with such force it caused the house to shake violently and made you fall over onto your back. The floor beneath her somehow remained well intact.
"Move aside puny versions of me!" said another Celestia with a deep voice… who was truly gigantic and stood even significantly taller than the Empire State Building. And for some reason her head had not bumped against the ceiling. "My enormous supernova prime butt is vastly superior than all your tiny, inferior butts."
"But--- said the other Celestias, in a desperate attempt to refute her.
In an instant the giant Celestia literally grew… twice as big along with even her massive butt getting twice as big.. her head somehow did not bump against the ceiling. The ceiling looked even further away than before. Somehow your house from the outside did not look any bigger than before.
"I am Apex Celestia! Your butts may be big and beautiful. But they are nothing compared to mine. My butt is the overpowered apex butt of the multiverse. My glorious butt has united my entire universe together in peace and harmony."
The other Celestias in the party looked at their butts in shame… none of them even coming close to the power of Apex Celestia’s gargantuan butt.
"So, Anon is going up stairs with me first. The handsome, yet puny human shall worship my giant glorious butt from under me!" she said with a nasty grin.
Apex Celestia turned around to slap her ass with her right hoof... the ginormous buttcheeks wobbled from side to side as powerful vibrations came out from the gigantic ass. The vibrations from her giant butt was so powerful it caused the house to shake on its very foundations… and caused you to fall over again.
The other Celestias bowed before her, they were in awe at the sight of such a massive butt.
"All hail! Apex Celestia!" all the other small Celestias shouted with their hooves raised high in the air in worship of her butt.
"Mwahahaha!" Celestia laughed maniacally as her body swelled even larger again, along with her already humongous butt getting even bigger by the second. "Is your tiny human body ready for this butt?" she said with an evil grin whilst she continued to grow larger and larger.
You stared in awe at the gigantic, heavenly butt as it inflated like a balloon, it was a truly enchanting sight to behold. Her divine, all powerful butt only got bigger and bigger, fatter and fatter, heavier and heavier. The continuously growing butt showed no sign of stopping, in fact the expansion of her butt and body only seemed to get faster and faster by each passing second. Words could not describe a butt, that got only more and more glorious. Drool began dripping out of your mouth as you continued to stare at the ever growing butt.
Until, you were reminded you were going to have sex with this butt.
You gulped nervously as sweat poured down your forehead as you stared up at the colossal butt that rapidly grew bigger and bigger before you. The ever expanding butt was massive and beautiful, but it was also truly terrifying to behold. "Uh… wouldn't you crush me under your butt’s weight?"
"ARE YOU SAYING I’M FAT?!" she roared in the Royal Canterlot Voice as she glared angrily down at you. Her body and butt stopped growing over such an insult.
"No! No! No!" you shouted in panic as you waved your hands in exasperation. Giant Celestia giggled softly with a hoof over her mouth. "What’s so funny?"
The next thing you knew Apex Celestia leaned down to face you… the only thing you could see was the giant head of Celestia taking up your entire vision.... even then, you could not see it all.
"Awwww! You look so cute when you're terrified, " she said mockingly with a nasty grin.
You said nothing… still to scared to speak. "Don’t worry baby. I won’t squish you. After all, I have magical powers to stop you being crushed under the beautiful, yet massive leviathan that is my butt."
"But… how could my humble human penis possibly--
"My magic would fix a little issue like that." Suddenly she groaned sexfully as she stared at you with bedroom eyes, whilst her tremendous butt got a little bigger. "So, what do you say human? Do you want a massive titan ass like mine bouncing atop of you?"
Your heart skipped a beat as you were red like a tomato. "Uh… can we perhaps do this another time?" you said nervously as you scratched the back of your neck.
"Awww!" she said as her lips pouted whilst she looked at you sadly.
"I’m sorry, I really do love your ass. I feel like mere bacteria before the glory that is your massive titanic ass."
A bright blush adorned her cheeks. "Really?" she said with her eyes sparkling in joy as she grew slightly bigger again.
"Yeah, you’re one dynamite lady."
"Aw, that’s so sweet." she said softly. "Oh human, I’m totally going to bounce my giant ass on top of you so hard," she said with a nasty grin as her body grew slightly bigger once again. "Ooh ooh! Maybe, me and you could go on a date together sometime. A date that shall involve you using my massive ass as a bouncy castle, perhaps? That would be so romantic," she said with a smile that was so cute it could kill… if she wasn’t a giant pony.
"Yeah, that sounds fun!"
Suddenly her massive tongue came out from her mouth to gently lick you across the face… lick your entire body... as a result, your whole body was now soaking wet from her saliva.
"I like you, my little human. I like you a lot," she purred as she looked at you with bedroom eyes. "You are such a gentleman."
"Thank you, my beautiful giant pony princess," you said with a warm smile.
Giant Celestia above you had tears of joy in her eyes…. before the tears hit the ground she teleported them away.
You looked at her in determination… deciding now was the time. "You know what, I think I’m ready for your glorious gigantic butt now."
"Tonight you shall praise the sun," she said with a nasty grin as she once again decided to grow herself slightly bigger.
You had a wonderful night with the greatest butt in the multiverse.
The End
