A Story Where No Incest Happens For Once
On a wondrous lavender night in the magical horse land known as Equestria the purple winged unicorn known as Twilight Sparkle was nestled snuggly within her warm home, which was a huge ass oak tree, with loads of books inside it.
For it was a library, a big huge ass library with lots of books… libraries tend to have lots of those.
Speaking of huge asses, this sexy pony had a rather plump fat butt, due to her sitting around most of her life while reading books, topped off with her mentor stuffing her with fattening cake to fatten up her glorious fat backside.
A big fat butt that will only get bigger and bigger, fatter and fatter due her being an alicorn with immortality. One day her butt could grow to be just as big, if not bigger than Princess Celestia's butt. Truly, one of the great woes of immortality is how big a pony’s butt gets over time.
But for now her butt, while plump and beautiful was pale in comparison to the other pony princesses’ bigger and fatter butts. For Twilight's butt was the smallest butt, still a big and fat butt, but not as big and fat like the other alicorn butts.
Of course, ponies in general had rather plump fat butts, but some ponies had bigger and fatter butts than others. Life was hard for an average pony, knowing no matter how hard they tried they would never get a fine big fat butt like an alicorn’s butt.
Anyway, her big purple fat butt was sat comfortably upon a large, soft, purple cushion. Before her stood a book stand, which she was using to read a book.
All was quiet, there was not sound in the room, save for the odd flick of a page. Until, all of a sudden the door flung open behind her, hitting the wall with a loud bang, followed by a white unicorn stallion rushing in.
“Sister, I want to bang your sweet fat butt!” shouted a masculine voice.
Twilight's left eye twitched over what just heard.
“Errrr… wha?” she said in a most bewildered tone, slowly turning her head to face her brother.
“You heard me Twilight, I want to bang your sweet fat butt!”
“But Shining, you're my brother! You can’t bang my butt!” she exclaimed, raising her hooves high in exasperation.
“That only makes it even hotter!” he said sexfully, looking at her sexfully with bedroom eyes.
“Ewwwww!” she shouted, covering her eyes with a hoof.
“Oh, cum on Twilight! Don't be such a prude pussy. Let me bang your butt,” he bellowed, nostrils flaring.
“What about Cadence? Surely you aren't going to just--”
“Fuck Cadence! I want to marry you and bang your sweet big fat butt with my big cock!” be shouted.
“But I’m your sister! So, we can't!” she roared, stomping her hoof .
“Oh, cum on! I’m your brother and I’ve got the biggest cock of the whole Royal Guard!” he protested.
“I don't care, I’m not fucking my own brother!”
“Cum on Twilight, I want to bang your butt! Your big and fat glorious butt!”
“No!” she roared, stomping her hooves.
“Oh cum on sis, you will love my big fat cock banging your sweet ass!” he pleaded, staring at her with pleading doggy eyes.
“I don't care how big your cock is, I’m not fucking my own brother!” she bellowed, hot steam emitting off her mane.
“Oh, cum on Twilight. I only live once, surely you could allow your own brother to bang your sweet ass before his mortality takes him?” he said softly, with a hopeful look in his eyes.
Twilight buried her face into her hooves. “Of all the years I’ve known you, I never expected you to ask me for sex,” came her muffled voice.
A smug grin came upon his face. “What can I say, your butt is amazing.”
“Can you please… talking about my butt. I doubt that's how you won over Cadence, talking about her butt all the time.”
“But… but… but… butt-butt I love your butt!” he said nervously.
“I don't care! Stop talking about my butt! It’s creepy!”
“But Twilight, your butt shall some day be the one butt to rule them all.”
“Just stop it already! Whatever you're planning is going to fail! For you don't win over mares by talking about their butt!” she shouted with thin slit angry eyes.
“Sure, that's how I got Candace,” he said firmly, smiling smugly.
“Then she must be a dumb whorse! No proper mare is so easily seduced,” she shouted, grinding her teeth together.
“Once they see my big cock they are seduced. Speaking of my big cock, how about I give your sweet fat ass a nice ride?”
Twilight sighed. “Again, you talk about my butt.”
“I can't help it! Your butt is just so big and fat.”
With that Twilight screamed in rage, her mane blazing with fire in anger
““STOP TALKING ABOUT MY BUTT! IT’S NOT BIG AND FAT! she roared in the Royal Canterlot Voice.
“Oh, cum on Twilight. Your butt is so-- Mmhhhh?!” he was interrupted by s summoned zipper over his month.
“I don't know what's got into you, but I am not hearing another word about my butt!” she shouted, giving him a death glare.
Just then… another… Shining Armour walled in.
“Hey sis, did you see my-- Aaaahha!”
“If you’re Shining, then who’s--” she was cut by powerful explosion of green smoke, causing both her and Shining to couch whilst blinded by the obscuring smoke.
By the time the smoke cleared, the zip bound Shining was gone.
“Fucking Changeling!” shouted Twilight, crossing her hooves.
“What he do? He didn't hurt you, did he?” he asked in a worried tone.
Twilight sighed. “He asked to bang me while looking like you.”
“Oh, that's so hot,” he said sexfully.
Twilight gasped in shock with a hoof over mouth.
“Only joking!” he shouted, a look of panic crossing his face.
“You fucking better have been,” she said quietly, looking at him with narrowed, angry eyes.
The End
