Princess Twilight Sparkle had become a horse princess.

She had magic wings and a magic horn, and was the only unicorn horse pony to even ever grow real permanent magical wings and become a horse princess.

Princess Celestia, biggest horse boss of all ponies, had said "Twilight Sparkle, I made you a horse princess because you are the most powerful small pony of all the small ponies, and I think it is time for you to be in charge."

Twilight Sparkle had made a big grin smile, and said "You won't be disappointed Madame Princess! Just tell me what to do!"

But Princess Celestia had sighed, her glorious white body moving with breath as she breathed. "Princess Twilight horse Sparkle, as a Princess, nopony tells you what to do. You are in charge of Ponyville. I'll come check on you in a week so don't fuck it up."

Before Twilght Sparkle, Ponyville Princess could say anything, Princess Celestia had turned around and flown away into the stratosphere, and the last sight that Princess Twilight Sparkle of Ponyville saw was Princess Celestia's glorious white ass soaring into the sky, and she could just barely see a mare nipple but maybe it was a speck. It was the most beautiful thing she'd ever seen, and she cried three tears from her left eye because it moved her heart and her groin with its beauty.

Then there was a scene break while Twilight Sparkle went to Ponyville.

Twilight Sparkle had put a giant crown on top of her library house with her magic horse powers and told everypony around that she was queen of Ponyville. Because Twilight was kind of socially retarded, and Mayor Mare was already kind of running things, Twilight Sparkle Princess called all of her friends over to tell her what she should do as Princess of Ponyville.

The shy one said "uh, um, I think that a hands-off moderation style really lets the community flourish" but Twilight didn't hear her because she was too quiet.

The fast one said "Be fuckin like, BAM, like, WHOOSH and then I'll do a flip like, PTCHOW! And can you make me a wonderbolt?" but Twilight only heard "Wonderbolt" because honestly the fast one had really not paid any attention to the question and that was readily apparent to Twilight, and so Twilight was just listening for a cue to say something again. Like "I need to go," or "See you tomorrow" or something.

The hyper one said a whole lot of things in very fast succession, mostly nonsequiturs and stuff about parties, but Twilight didn't hear it because she honestly never listened when the hyper one said anything.

The gorgeous one said "Darling, one must behave at all times with poise and grace. If your subjects love and respect you, then you may use a gentle hoof to guide them and they would gladly follow." But Twilight didn't hear anything she said, because Twilight was staring deeply into the gorgeous one's eyes and following the curve of her soft, silky hair and how it lead to the curve of her ass and was it getting hot in here?

The apple one said something about ... something? Twilight honestly didn't remember asking the apple one for advice at all. Or to come over. Or like, really remember to acknowledge her in any way.

So Twilight had her advice. Her sleepy baby slave told her just to have fun and do what she wants, and that Celestia would probably be proud of whatever she did and would want her to take the initiative, so Twilight laid in bed smushing her dark horse labia most of the night, taking the advice of a baby child and thinking about what she really wanted to do.

The next morning, Spike went into the town center and shouted a proclamation.

"Hear ye! Hear ye!" Spike said, wearing a stupid squire outfit, "Princess of Ponyville, Twilight Sparkle the Pony Princess, hereby formally requests the presence of Mr. Cake and Big Macintosh at high noon this day of horse days!"

Everypony heard him and then he went back, sending a letter to Canterlot and a letter to Cloudsdale.

There was a line break to signify time passing, before high noon arrived.

Big Macintosh slowly approached the horse tree library of Princess Twilight Sparkle. He saw outside the front of it that Mr Cake was there, as well as Soarin from the wonderbolts, and Princess Twilight horse Sparkle's own brother Shining Armor, and also Iron Will the minotaur. He walked up very slowly and whispered to Mr. Cake, who was the only horse there he really knew.

"What's this all about?" he whispered. He said it all with a country accent but Mr. Cake sort of mentally just translated it, you know? Like if you talk to people with deformed faces all day at first it sounds like gibberish, but after a while you can understand them.

"I have no idea," Mr. Cake, who was kind of an idiot, said stupidly.

Big Mac didn't know any of the other horse people, so he just stood there and chewed a hay.

Right exactly at high noon, Princess of Ponyville Twilight Sparkle appeared in a flash of purple light on the balcony above the horses and minotaur. "Loyal Subjects!" she squealed, "I have brought you here today because I can do whatever I want! And my almost terrifyingly-abnormal horse brain has decided I want to measure your testicles and see which ones are the biggest! I have selected you because you are the only boy ponies I know!" She paused, "And a minotaur."

They all sort of muttered and mumbled to each other like a pantry full of otters. Apple horse, who was walking by at that time in the background, said "Hey Twilight, wasn't there some other boy horse you met? When you went through that magic mirror?" but thankfully Twilight Princess horse Sparkle ignored the apple horse completely.

In another flash of light she appeared on the ground behind the male horse boys and a minotaur. She was closest to Mr. Cake. They all started to turn around when she appeared in front of them in a brilliant flash of light and screeched "NO! Look this way so I can get to your horse testicles!" and then appeared behind them again in a flash of light while they all mumbled and murmured like if a bunch of otters were trying to hide in a laundry hamper.

Mr. Cake and Twilight Sparkle's horse brother Shining Armor started to turn, but they felt the cold brush of magical horse unicorn power holding them in place. It wasn't nice like somebody brushing your mane and tail with a tiny plastic brush. It was more like, if ice was greasy and fat. The magic gave the impression of being really greasy and fat.

Shining Armor horse said "What the fuck Twiley. This is kinda retarded. Plus I'm a prince so technically we're the same rank."

Twilight sparkle croaked out a laugh. "Whatever. You only have jurisdiction in the Crystal Empire, and the separate sovereigns rule implies that when you are in the lands under my power, you consent to my rules so nyeh!" she made a gross face with one nostril flared, but Shining Armor couldn't see it.

He said "I'm gonna fuckin' tell on you to my wife and she's gonna kick your butt!"

"More like kiss my butthole!" Twilight said, using magic to wrap a measuring tape around Mr. Cake's balls. "23 pony horse units in diameter," she said, using magic to make a note on a clipboard. By this time there were several onlookers.

Shining Armor didn't say anything because of the sick burn Twilight Sparkle Princess just handed down. Shining Armor always kinda froze up when he got served with a sick burn ever since he was a kid and some other kid called him "Shining Butthole."

With a flash, Twilight teleported behind Soarin. Mr. Cake asked if he could go and Twilight ignored him, using magic to cut off Soarin's fancy Wonderbolts flight suit just in the back so she could see his horse testicles and all that.

Twilight said "28 pony horse units" she said, nodding. Soarin said "Why does your magic feel so sweaty? Also the letter said this was a paid appearance so w-"

"No," gurgled Twilight Princess Sparkle, applying some pressure to Soarin's horse testicles with her sweaty magic. He shut up pretty quick.

With a flash of magic she appeared behind Shining Armor.

"Twiley, you better fucking not touch my balls," he said.

He felt a sweaty point of magic run in a line between his balls.

"Fuckin' Twiley? What did I just fuckin- son of a fuck!" He felt something really hot and wet squishing on his balls while magic pushed on his puffy horse asshole.

"Fuckin Twilight horse fuckin' Sparkle you stop right this-" then the wet thing touched his horse anus while the magic cupped his balls. "Is that your fuckin' you'd better not be fuckin' this is fuckin' creepy I'm your fucking brother!"

"Haha he's getting a boner!" some light blue lesbian horse in the crowd said to her horse lover who was a garbagemare.

Twilight Sparkle appeared in front of him with a flash of light but the feelings stayed back there.

"You dumbass loser," Twilight Sparkle said, even though that was a slur against donkeys. "I'm just fucking with you." She laughed so hard tears came down her face like semen down a horse's pony face if it was water instead of semen and in her eye but you know still a little bit salty.

"Haha, what an idiot. You thought-" She stuck out her tongue, "Haha as if! Seriously?" With a flash of light she appeared behind him and said "What a fuckin' joke." She burst out laughing. "18 pony horse units. What a fuckup."

The feelings left his nuts and Shining Armor collapsed from pure shame. A little vomit came out his nose and he cried tears that weren't from laughter though. Well, technically they were, but not from his laughter.

With a flash she teleported behind Iron Will the Minotaur. He'd been strangely silent the whole time. He spread his legs slightly and everypony gasped and a few said stuff like "Holy shit!" or "Celestia-daaaaaaaaayum!" or "Them's some big ass nuts!" and basically everypony cheered.

"Ho-lee fuck!" Twilight Sparkle, Princess of Ponyville said. "Fuckin' sixty three pony horse units..." her voice was a quiet whisper of awe. Like the sound a butterfly might make if it was swallowing a fart.

"You fuckers are free to go!" Princess Twilight Sparkle said, Teleporting in front of them. Using her magic, she lifted Iron Will up on the balcony and then teleported up herself, quickly going inside.

There was a page break to denote a scene change as the crowd erupted in cheers and the male horse ponies either cried or else went home or else had kind of confused boners and just stood around.

Princess Celestia, most powerful of all horses and biggest pony horse, arrived in Ponyville at Twilight Sparkle's library headquarters. She used horse magic to disintegrate the giant crown, mumbling "what the fuck" under her breath.

She knocked on the balcony door with a perfectly formed horse front hoof, but nopony answered. Child slave dragon Spike didn't answer either.

That was really unusual so she knocked again. Then she noticed the balcony was swaying slightly under her hooves.

She pressed the most beatifully-shaped horse ear in all of creation up against the door, and faintly made out a voice saying "If you want more minotaur nut, then put your tongue up his butt!" followed by an audible fist pump.

She touched the door with her glorious unicorn horn, so thin and straight and majestic. It made ponies swoon just to think about that horn, and the door popped open like an exploding ghost.

Crusty dried jizz covered every available surface. Books were scattered everywhere, the bedsheets and pillows and crap were dangling off the balcony and the ceiling, coated in gross spunk, and Iron Will the Minotaur was crouched, facing over the balcony, with Twilight Sparkle Princess behind him. Her hair and tail were sticking up in a bunch of angles, like if you put five weasels in a Chinese takeout container and then opened it up suddenly, and it was all glued in place sticking up like that with jizz.

Iron Will's huge balls were slapping Twilight in the face, and her orange tongue was just barely visible between his buttcheeks.

"WHAT THE HOLY FUCK IS GOING ON IN HERE?" Princess Celestia shouted.

Before anypony could explain anything Princess Celestia stomped into the house, her mane and tail flared up like it was a rainbow pastel storm, like if a kid ate a box of crayons and then was just throwing them up forever.

"WHAT THE FUCK? WHAT THE ENTIRE FUCK?" She shouted.

"Girls like a man who takes charge," Iron Will said, pumping his fist audibly. "It's like I always say, When-" But Princess Celestia shot a beam of golden light horse energy at him and he vanished.

"What did you do?!" Twilight Sparkle Princess said, hiding under the bed.

"Oh me-dammit," Celestia said, stomping her perfect hoof, the silhouette of her ass outlined against the sunlight from outside, "I just sent him home is all." She made that eyebrow face like they do in Pixar movie covers. "I mean seriously I'm like, not gonna hurt him or anything geez."

"Oh, yeah. I guess." Twilight muttered horsely.

"But me-fuckin' damn, Twilight, what the whole entire fuck?" Celestia frowned, her lips turned down. Her gorgeous, full horse lips on her narrow, perfect horse face. Twilight came just the littlest bit. "This isn't remotely what you were supposed to do. Where the fuck is Spike."

"Hiding in the kitchen cabinet," Twilight said.

"Aww maaaaaaayun! How'd you know?" Spike yelled from downstairs.

"Duh, Spike, you're kind of an idiot. It's where you always hide." Said Twilight, making the same Pixar movie cover eyebrow face as Princess Celestia, although it wasn't nearly that hot.

"Dang" said Spike.

"First, Spike, Clean up all this cum everywhere," said Princess Celestia.

"motherfuck," said Spike under his breath.

"What did you say?" said Princess Celestia.

"Uh, just, uh, nothing," said Spike, getting a mop and a sponge, "I didn't say a dirty word I was just uh," he peed a little but quickly wiped it up.

"Second, Twilight, you're fucking terrible. I'm taking you back to Canterlot and throwing you in the dungeon."

"Are you going to punish me?" asked Twilight. Her voice was full of trepidation.

"Well, no fucking shit," said Princess Celestia, tossing her mane over her back with a sigh.

"You'd better do it personally," Twilight said. Her blush was invisible under all the cum dried to her face, "so that it's perfectly appropriate to the crimes I've committed." She paused a bit and made sure her tail was covering up her crotch. "Plus it is just so embarrassing coming from you, who I look up to so much." Twilight didn't pee a little, but something made a spot on the floor underneath her if you know what I mean.

"Yeah, I guess that makes sense," Celestia said, tapping one amazing hoof edge against one soft, perfect lip. "Okay sure."

She surrounded them both with the glow of magic and before they teleported straight to the Canterlot dungeon, Spike could swear he heard Twilight say "score"

THE END

Author's Note

This is a story about how it would really happen if Twilight was in charge of Ponyville. There might be other chapters later on or something, but maybe there won't be. Nopony really knows for sure.
