Canterlot High School. An educational facility on the raise. A place where young minds, and recently their bodies as well, were molded, under the caring eyes of its principal, to prepare them for the world (so the principal believes).


At least that's how it is… in one world.


“These damn brats are going to be the end of me!”


This Canterlot High was not a school a going through a (admitly, sexual) renaissance, but rather one of the lowest ranked schools in the county, if not the state. And the principal of said school was none too pleased about that.


“Useless, the whole lot of them,” Principal Celestia bemoaned. She was a woman of average build, though slightly above average height. Her hair a rainbow of dark lavender, blues, and greens that extended down her neck, stopping just above her shoulders, and curling at the end. She was clad in a dark purple blouse and pants. “Dozens of students, not one of which is worth a damn in academics or athletics.”


Celestia was currently, sitting at her desk in her office, venting to her most sycophantic student.


Sunset Shimmer stood ramrod straight, her right hand clasped onto her left wrist in front of her stomach. Her bright yellow and red hair making her stand out like a sore thumb against the dark blue and purple of the office.


“W-well, what uh what about… me?” Sunset offered.


Celestia gave her student a sidelong glance, then spoke, “If A’s were give for brown-nosing, Sunset Shimmer, you would be unparalleled. Alas they are not.”


“W-w-well,” Sunset tried again, trying to ignore the sting of her principal’s disappointment, “Um, well, CHS certainly made waves at the art competition last week.”


“Ugh, don't remind me of THAT disaster,” Celestia said bitterly.


Rarity, the schools self-described “artistic genius”, had entered her latest masterpiece, a bizarre sculpture that bore little resemblance to anything on this earth. Celestia had begun to wonder if the girl’s mind had been touched by some eldritch being from beyond this plane. That one of the judges of the art show was alleged to have attempted to claw out their eyes did nothing to undo that feeling.


“Well,” Sunset tried one more time to find something that would cheer up her principal, but this subject was not something she would bring up if she wasn't desperate for a ray of sunshine to offer up, “There's that new the girl. She's supposed to be pretty smart, right?”


Celestia gave a mirthless chuckle at that, “I only took in that one because I might have gotten some inside information about Crystal Prep, fat lot of good that's done. If Cinch wasn't such a softy, she would have expelled Twilight Sparkle long before the explosion. Well, she's Luna's problem now.”


“But why would you need a student for inside info,” Sunset queried, “Doesn't your niece work there?”


“As if I could actually trust anything Cadance gives me!” Celestia snapped, causing Sunset to take a step back. Celestia calmed herself then waved her hand dismissively, “Get out of Shimmer, I need to think alone.”


Sunset wanted to argue to stay, but knew better, so she hang her head in defeat, “Yes ma'am.”


X X X


Sunset Shimmer was a stranger in a strange land. She had, in fact, come from a different dimension, a land of sapient, magic wielding equines called Equestria.


In Equestria Sunset had been apprentice to its magnificent and glorious ruler Princess Celestia, a position Sunset reveled in, faithfully serving her mistress without question, inspiring envy in her peers she never doubted.


Celestia’s glorious reign, however, had not been accepted by everypony. A group of selfish fools had formed a rebellion, led by the so called “King” Sombra.


Sunset had been zealous in hunting down those that dared to oppose her mistress, pursuing any lead on Sombra, no matter how small it seemed. And it was that zeal, she would realize in hindsight, that would be her downfall.


Sunset had received a tip, that the was going to be a big meet up of rebels to plan an attack on Celestia’s palace. She had taken this information instantly to her mistress, eager to please and put any worries she might have to rest. The tip, however, had been given to her by one Twilight Sparkle, and had Sunset not been so driven in ending the rebellion, she probably would have put the work in verifying it personally, before reporting it to Celestia.


The tip, of course, had turned out to be a trap, that Celestia had barely manage to escape. The Princess, naturally, was enraged. Enraged at her apprentice, for falling something so obvious. And thus, Sunset Shimmer was stripped of her position and banished from Equestria through a magic mirror.


The mirror had been a creation of Starswirl, known as the “Mad Mage” (though never to his face), Celestia’s own teacher and predecessor. It was said Starswirl had banished a trio of monsters that had threatened his rule.


Upon arriving in the world through the mirror, Sunset had found the only monster around was herself. Her body she found, after traveling through the portal, had been transmogrified into some kind of bipedal creature with two five digit hands. The first thing she used these new fingers for was to attempt to claw her way through the statue she ended up next to, but to her despair she discovered that the ride through had been a one way ride.


Eventually, Sunset Shimmer explored her surroundings, not having to go far to find the high school, and it was there she found a ray of hope.


Celestia. Though one of the strange creatures that inhabit this world, a “human” they were apparently called, and a principal rather than a grand and glorious princess, it was unmistakable to Sunset that this was Celestia. The way she carried herself, the way she sounded, the way she looked down on all those that were inferior to her and who should be eternally grateful that her gaze fell upon them for even the briefest moment. Sunset had only been away from the Celestia of her homeworld for a few hours, but boy had she missed that look.


Sunset had immediately bowed before the principal and swore her undying loyalty to her. Celestia, for her part, was initially confused by the act, but reasoned Sunset was must be a foreign transfer student and this was some custom, Sunset just rolled with that. Though the principal nearly had the girl committed when she spoke of “magic ponies”.


It took some time for Sunset Shimmer to earn her place at principal Celestia’s side. Fetching her coffee or whatever else Celestia desired, snitching on other students and even teachers if she felt they weren't in line with the principal’s vision, anything to prove herself useful. She swore she never fail this Celestia, but it just wasn't enough.


‘If only I still had magic,’ Sunset thought to herself. She had managed to fill the Celestia shaped hole in her heart, but the feeling of magic, of power coursing through the horn on her head to do even the simplest of levitation, was not so easily replaced.


Sunset Shimmer walked down the halls of the school dejected, not caring for anything going on around.


Such as the the young red hair girl picking on a girl of equal age that had light purple and white hair.


“Howdy, DT,” the redhead, Apple Bloom, said in a faux-friendly way. Apple Bloom is wearing a red shirt and a dark blue skirt, though real eye catcher is the gold necklace she wears with a green apple shaped jewel making sure everyone knew she came from money. Presently, Apple Bloom had the other girl pressed up against the lockers, her left hand on the locker next to the girl’s head to make sure she had her full attention.


“H-hey, Apple Bloom,” Diamond Tiara responded nervously. She wore very plain clothes, browns and the like, it was well known how poor Diamond Tiara's family was and next to Apple Bloom it became all the more obvious. “Is um is there something y-you need?”


“Why, as a matter a fact there is something I could use your help fer,” the rich girl said, continuing with that tone, “Ya see, I been so help out my family out with this and that, that I done plum fergot to do my math homework and my english and that 200 word essay on the battle a where-ever for history. So, Imma need you to do same of they fer me, like, all of it.”


Diamond Tiara’s gaze turned away, or tried to anyway, in shame, “That's that's a lot of work…”


“I have every confidence in you,” Apple Bloom interrupted.


“An-and I have my own homework to do,” Diamond Tiara continued, “And I have to help around the store.”


“Look, DT, you doing this for me will help out family's store,” Apple Bloom moved her hand off the locker and onto Diamond Tiara's shoulder, a smile on her face that was anything but friendly, “You do this stuff for me and I'll talk to Granny about easing up on what your parent’s hafta pay.”


Sunset walked by the whole scene without sparing it a second glance. The right to rule by the powerful had been the way of her Celestia, she had no pity to spare the poor girl, she had real problems to deal with.


Sunset brought herself to the school library, perhaps some studying would help her raise her grades, so that she might please Celestia. While it was a plus there wasn't any life or death stakes in this new life of hers, but if she did not have Celestia in it she had no reason to live.


Entering the library, Sunset finds it practically deserted, save for one individual.


The girl sitting at a desk readings, was rather pale skinned, had blue hair done up in a bun behind her head. She wore a blue vest over a white dress shirt with blue pants and a blue bow tie to top it off. She had ear buds on, and if anyone knew Vinyl Scratch, she was no doubt listening to something classy and soothing.


But that now came crashing to an end.


“Oi! Vi, watcha lissen’ to?” the new girl let herself known quite loudly. Her black hair was shaped up reminiscent of a mohawk with a bright pink streak. A pink shirt under a black leather jacket with studs on the collar, tattered jeans, and round pink earrings with treble clefs on them. The punk rocker of CHS: Octavia.


“Betcha it's nota's good as the lates’ Semi-Automatic Luv,” without even letting Vinyl respond, Octavia unplugs the ear buds from Vinyl’s phone and hooks it to her own. Vinyl fought back a scream, her eyes bugging out as her ears being assaulted by loud rock “music”, an undoubtedly defiant number railing against society, the police, or some such authority. At least that's what Vinyl would assume if she could understand this gibberish, or was able to think through this racket.


Taking the phone out of Octavia’s hand Vinyl hit the stop button, pulled the buds out of her ears, and took a deep calming breathe.


“Octavia,” Vinyl’s voice was elegant and precise, “While I try to keep an open mind to different kinds of music, I would greatly appreciate being asked first.”


“Awrote, but wasn't it…”


“Furthermore, it is wildly inappropriate to be shouting and making such a scene in the school library,” Vinyl cut her friend off, the last three words coming through her teeth.


“Aw c'mon now Vi, there ain't no one ‘ere, now is they?”


“Be that as it may, we are still on school grounds, had you considered that the hall monitor might be around.”


The punk rocker went quit and still at the thought, “She uh she ain't ‘ere is ehe?”


“Since we are not currently cowering in fear I don't think so.”


Relief flooded Octavia as she let out a sigh of relief, “Well I'm gonna scapa just ta be safe.”


“Yes I suppose I may as well leave too,” Vinyl got up and rubbed her temples, “And you can treat me to something sweet for this headache.”


Octavia had a soft smile on here face, “You got it, luv.”


And with that the strangest pair of friends at CHS left the library, having never even noticed the principal’s toady, who fortunately for them had decided this scene was not worth the principal’s time, given hat she was actually concerned with.


Sunset Shimmer now with some peace and quiet, turned her attention to the book shelves, feeling history was a subject worth brushing up on, she scanned the shelf for a book that seemed relevant. Then her eyes on something that seemed out of place…


A book. Which shouldn't seem odd on a bookshelf, but Sunset was sure she had glanced at this spot a few times and it had not been there a second ago. Surely, she would noticed this book, it seemed to glow or perhaps… shimmer?


She picked up the book, it was purple with a heart on the cover, and as she held it in hands, her eyes settling on the heart on the cover, the book definitely glowed and Sunset felt a familiar feeling she had not experienced in this world before.


“It it can't be…” Sunset was dumbfounded, as a tingling feeling went from her hands, through her arms, and then throughout her body, but she did not notice the growing of her legs, her butt, her breasts, all ever so slightly, or that at the end of her hair the red had turned purple. “It is! It really is! It's magic!”


This was it! This was the answer to her prays! How could Celestia not be impressed by such a fantastic gift as actual for real magic?!


Not wasting anymore time Sunset left the library to make her way back to the principal’s office.


X X X


Principal Celestia was still in her office, now using her computer to look up the Everfree Spa and Resort, longing for something to melt the stress of her joyless dead end job.


That daydream came crashing to an end with her door crashing open, “Principal Celestia, Principal! I found something amazing.”


“Given that you were able to open the door, Sunset, I assume your hands are intact, so why could you not knock on it?”


“I'm sorry ma'am, but you need to see this,” the girl proudly presents her prize.


“Your diary?” Celestia asked stone faced.


“No, no, do you remember what I told you about where I came from?”


Celestia pinched the bridge of noise, “Not the magic ponies again.”


“Well more the magic part than the pony part,” Sunset tried pointing out, not wanting the principal to think she was crazier than she already did, “This book has magic, I can feel it! Please let me show you.”


Normally, Celestia would have dismissed Sunset Shimmer's magic talk, but with the mood she was in right now she decided to humor the girl, if only to get her to leave, “Very well Ms. Shimmer, go on, wow me with your ‘magic powers'.”


Sunset opened the book and found odd text or symbols within, like some kind of cipher. She didn't actually need to read it, however, the power within the book was already guiding her to do needed to be done.


“Give me your hand, please,” Sunset reached out her right arm, offering her hand to the principal, her glowing with purple light hand. Celestia’s eyebrow raised, now fully intrigued, or perhaps entranced was a better word, and reached to take the hand.


As soon as their hands grasped one another, a jolt shot through Celestia’s body, stronger than any static shock she had ever felt.


Celestia felt her warmth all throughout her body, her skin tingling, vibrating. She couldn't fight back the moan building up, “Ooooh wow.”


Celestia's hair grew fuller, longer, beginning to move down past her neck, past her shoulders. On her neck the thin gold chain grew into a gold chocker.


“MMMM! Yes, fuck… yes,” Celestia bit her lip to stifle her moans, but ended up letting go as they puffed up and became covered in purple lipstick that was a lighter shade than her clothes. That was not the only changes to her face, any lines or other signs of aging had melted away, leaving a much younger, if still stren, looking visage. The principal closed her eyes, eye shadow matching her lipstick now appearing, giving herself to the sensation running through her body.


Celestia's stomach became taut as any fat there was redistributed to better places, such as her ass and hips. She ran her fingers over her flat belly, nails growing as she traced them over and over there, now painted the same color as the make-up on her face.


Legs lengthened and thighs thickened. As ass and hips grew more and more, the administrator's waist ended up above her pants, part of her now smooth hairless crotch could be seen, but her actual slit was still hidden from view.


And of course, the chest. With each deep breathe Celestia took, with every heave of her chest, her boobs expanded, scratching the bra they were confined in, pushing her buttoned up blouse further and further to its limits, until…


POP POP


Celestia's eyes snap open at that sound, the trance she seemed be in now over. She looked down to where the noise had originated from and was shocked at what she found. Cleavage. A small canyon of cleavage. HER cleavage.


Standing up in surprise, the principal had hold on to her desk to steady herself, as the surprises continue to amount. It seems that her shoes had been replaced with, or turned into, high heels. Though Celestia did not wear heels often, it did not take her a second to find her balance upon realizing what kind of footwear she now had.


“What, what have you done to me!” Celestia exclaimed, as she examined herself. Bust size increased by ten times it seemed, straining the last two buttons of her blouse, top of her black bra displayed, her hips grown out even more than that, her now tight pants barely concealing her nether region. The principal turned her gaze to the cause of these changes, “I look like like some kind of slut! Fix me NOW!”


Sunset quickly flips through the book, trying to find some undo spell, but was having no luck, “I uh I don't think… I… can?”


“Oh well, just fucking perfect! I can't wait for the board of education to find out about this! You little…”


“Principal Celestia,” before Celestia could tear into Sunset, the door to her office opened, and in walked the principal’s bespectacled, brunette, and rather lazy, secretary Raven, “I have forms from Harshwhinny for some outdoor classes or some crap. If there's nothing else you need, I'm gonna knock off for the day.”


Raven dropped the papers on the desk, and stood and waited for a reply, seemingly unfazed by the radical changes that her boss had gone through.


Celestia finally spoke after a few seconds, waiting for some reaction, “Raven, does there seem to be anything different about me?”


The secretary looked the principal up and down then offered, with disinterest, “New mascara?”


“Never mind,” Celestia shock her head, “You may leave Raven, I believe I have all I need.”


The secretary left with a nod and not another word.


“She didn't notice? How did she n…” before Celestia could finish her train of thought her mind was flooded with memories of her life. She had developed this bombshell body at a young age and know how to use too, becoming a undefeated pageant champion in her teens, she would have keeped at it but decided to enter into a career in education, officially guide young minds, but in reality to regain over them with her superior body.


“Mmm, how interesting,” Celestia walk over to the full body mirror, that had always been in her office. She undid the last two buttons on her blouse, they were all too happy to give away, as did her bra strap, completely removing all coverings on her upper body, allowing her newly expanded flesh to be free. Staring at her new self in the mirror, Celestia brought her hands up to her tits, groping them, squeezing them, bouncing and jiggling them, pinching and pulling her nipples, and digging her long nails into the soft mounds. “Mmmmmm, yeeees these are very lovely.”


As fun as her fun bags are, Celestia wanted to see the rest of herself. Moving her hands down to her pants, tracing and tickling her stomach with her fingernails, she wasted no time removing her bottoms (though she managed to keep her heels on) standing bare in front of the mirror. Running her hands down her thighs to her knees, Celestia began to bend over and ended up squatting, her legs spread as wide as they could go. She ran her fingernail over her pussy, bottom to top, “Oh how wonderful!”


Springing up with a spin, Celestia gazed at the reflection of her now plump rump. She moved her hands around to squeeze her cheeks, enjoying the give of her ass flesh, then concluded with a hard smack setting her cheek to jiggle, “Ooh, that does feel nice!”


“Sunset Shimmer,” at last the principal turned to the cause of this transformation, the girl had been enthralled by the show Celestia had just put on, but now had been snapped out of as the attention was shifted on to her. Celestia stepped towards Sunset, the girls eyes following the bounce of her breasts, “You have brought me a wonderful gift.”


“You're... pleased?”


“Very,” Celestia stood mere inches from the girl, her boobs all that filled Sunset’s vision. Celestia arms wrapped around Sunset, pulling the girl’s face into her bosom, “The ability to shape the bodies and perhaps even minds of anyone I wish? How could I not be pleased?”


Celestia felt her tits getting wet and Sunset start to sob. She rolled her eye at the girl emotionally state.


She may not be able to turn Canterlot High School into a prestigious and enviable educational faculty like Crystal Preparatory Academy, but turning it into her own personal harem was not an unappealing notion.


‘Why stop at the school? There's a whole city out there,’ the thought shot through Celestia's mind and her smile grow, ‘Let's just take this one step at a time.’
