Twilight is jealous that despite being a princess she is ignored because of her size. Enter Discord whose magic gives Twilight a taste of authority by switching curves, stature, and more curves with Celestia.

Despite being a princess, Twilight's body just doesn't stand out or garner the attention her royal STATURE deserves. Eager to help, Discord switches Celestia's and Twilight's body types. Now large, Twilight finds herself in charge as everypony looks (and lusts) after her new figure.

Chapter 1

The Authority Figure

“Excuse me, could you help me…and he’s gone, Twilight.” Twilight Sparkle sighed loudly in frustration, not even that seemed to garner herself any attention. Around her rushed servants, royal guard, bureaucrats, nobles, and so forth through the hallways of the Baltimare Royal Palace. The royal palace in Baltimare was normally the regional administrative hub for the Equestrian government in the Baltimare city and local province and was used as the royal quarters when the heads-of-government were in the city. In other words, unless the Princesses were in the city the building was where you went if you needed to complain about your taxes or if you were visiting from Porka-Porka or Griffonstone and needed a visa to extend your stay in Equestria. Twilight judged from the low hum of herd panic and tension she had carefully observed from the local officials it seemed that the message that Princess Celestia would be staying in Baltimare for several days to launch a newly commissioned ship at the naval yard had been lost in the mail.

“One would think the fact that I have a horn and wings would…would get their attention!” Twilight’s feathers were absolutely ruffled, not just metaphorically but literally as well, several frantic ponies had already knocked her wings aside to get past her. She had already begun to regret accepting Celestia’s invitation to join the royal launch, but despite several years as a alicorn princess she still hated to disappoint her teacher. The sweet memories of her time in Canterlot’s palace flashed in her mind. “Maybe, if this was Canterlot, everypony there knows me.”

“Weeeeeellll, you don’t exactly strike an imposing figure, now do you?” Discord commented as he popped into existence in front of Twilight.

“GAH!” Twilight nearly knocked herself over, jumping back from Discord’s sudden appearance she had been sidelined by a rushing Royal Guard whose sturdy frame easily sent Twilight rebounding several steps into another mare trailing paperwork. The mare amazingly, perhaps from years of practice, used Twilight’s momentum by pushing Twilight back toward Discord and propelling herself forward and down the hallway. Luckily for Twilight she had managed to right herself before she crashed into Discord. She huffed and looked over the serpent-bodied Draconquus.

“Discord, what are you doing here and why are you wearing…that?” Twilight asked, looking at the shirts Discord wore. Underneath an open, button shirt that had tropical floral patterns he wore a second shirt with an image of a completely cartoonish Fluttershy.

“What am I doing here? I absolutely loooove Baltimare,” Discord replied, reaching up into the air he pulled down a full map of Baltimare city with several points of interest circled in red, “The hoofball games. They have a lovely aquarium that Fluttershy just adores. Not to mention the convention center. In fact, I am staying at the Hoofton for a little get together of likeminded fans of a tv show, nay, internet phenomenon called- “

“Fine, enough!” Twilight sighed exasperatedly, she did not need Discord’s antics now. Though, his earlier words struck a chord with her, “…what did you mean earlier? About an imposing figure?”

“What don’t you know already, oh pretty, pretty princess?” Discord asked with mock shock, snapping his fingers he reappeared in a brightly colored and significantly poufy dress that would have sent Rarity into a state of shock. With another snap of his fingers he returned to his previous attire, “An imposing figure. Ponies just look at you and know you are in command! In other words, you don’t exactly look like an…authority figure, not like Celestia.”

“Discord!” Twilight shouted, though despite herself an image of her mentor did flash in Twilight’s mind. A bright blush covered her face before she shook it off. “I’m not like Celestia.”

“You can say that again.” Discord replied, leering at her his eyes drifted over Twilight’s body from her hooves to her hands to her chest to her face to her chest again. “Nope, no wonder you are being overshadowed. All you Ponies are herd based. You look for the largest of your kind and follow them. After all, isn’t that why you still follow Celestia like a puppy? You just want to curl up right ontop of her big, round-”

Twilight felt her blush deepen, to be looked at like that from Discord made her feel like she needed a bath but what he was talking about made her want to jump into a decontamination shower.

“I-I-I think you should go! Please, don’t cause any trouble for Celestia.” Twilight kept herself from screaming the words, barely. Instead she used her magic to wrap a telekinetic field around Discord and push him back toward the direction of the entranceway.

“Very well. I can tell when I’m not wanted.” Discord said before disappearing with a loud pop. Twilight felt relief flood her veins, she was having enough trouble finding Celestia. She did not need Discord messing around.

Then Discord popped back into the hallway.

“Byyyy the way. You will find Celestia down that hall, up the stairs and the third door on the left.” Discord pointed behind Twilight. She hesitated. Should she trust Discord? Normally, his pranks came with a catch or used a pony’s desires against them. Twilight reasoned his words were harmless.

“Thank you, Discord. I, uh, appreciate the help.” Twilight did her best to smile at Discord.

“Of course, of course. I am always happy to help!” Discord beamed and once again disappeared from the hallway. Twilight paused, waiting to see if he had finally left. After a minute Twilight decided that Discord had indeed left and turned down the hallway to follow Discord’s directions. No sooner had Twilight left the hallway, Discord popped once again into the hallway. “Always happy to help Twilight. No need to ask. I am sure Celestia is just as happy to help too…”

“Muwahaha!” Discord laughed, his claw and paw raised in the air.

“Out of the way!” a cart filled with freshly printed copies of Equestria’s law encyclopedia barreled into Discord from behind, sending him flying end over end through the air and into a wall. The pony behind the cart made an apologetic gesture before he rushed down the hall.

“Ugh,” Discord groaned, “I hate the law…s of physics.”

Upstairs, Twilight was happy to see that Discord’s directions appeared to have been right. The door Discord had pointed her to seemed to lead into an open spaced receiving room, almost like a throne room but smaller. A line of ponies stretched out the door and crowded in the room itself. Walking toward the doorway she glimpsed the tips of Celestia’s wings and immediately her blood began to pump faster in her veins again. Celestia did stand hooves and hands over everypony else. Twilight felt flustered as she banished Discord’s words from her mind again which is why she may not have noticed the royal guard pony motion for her to stop and when she did not grab her and haul her back.

“Sorry, m’am. No, cutting in line. Royals, royal guards, royal servants, and royal officials only get to skip the line. You’ll have to wait your turn like everypony else.” The royal guard rumbled at her. Twilight gaped for a moment, he was particularly large for a royal guard pony. He noticed he did not have any wings or a horn so she reasoned he must have been one of the local Earth Pony recruits. Something about him did remind her of Big Mac, not that she was racist and she thought all Earth Ponies looked alike. Underneath his plated armor and orange coat, muscle bulged and even though Twilight had gained several inches in height (if not much elsewhere) after her ascension he was still taller and broader than her, only Celestia or Luna could top his height and width. Before she spoke she softly licked her lips and tore her eyes from his biceps to look into his eyes.

“I-I am Princess Twilight Sparkle! I am a royal!” Twilight point at her own horn and flapped her wings behind her, her wings making a weak breeze. Twilight had grilled Rainbow Dash and Fluttershy on the dynamics of Pegasus social norms and culture, especially when it came to wing signaling and use. She had asked both if her wings were the proper size, neither had looked at her straight when they replied and said her wings were ‘Fine, nothing like Celestia’s but that they were average’. Twilight was able to use them to fly properly, if not particularly fast, so she had been satisfied that her wings had adequate function over form. After Discord’s words, however Twilight couldn’t help but think her wings felt pathetic and remembering the comparison to Celestia something twisted inside of her.

“Oh! Princess Twilight Sparkle!” the Earth Pony Guard blushed as he bowed and apologized, “I’m terribly sorry about that. I didn’t recognize you. I mean I’ve seen your picture of course! Its just, well, your not-“

“It is fine! Fine! Fine! Fine!” Twilight interrupted the Earth Pony Guard before he could finish he sentence. A manic edge had crept in her voice. She did not want to hear what he was going to say. That she was not as big as he imagined. She was not as majestic as he had thought. She just wanted to get through and see Celestia. “I’ll just be going on in. To see Celestia. My mentor of so many years. Who I am co-co-ruler with. You know, since I have saved Equestria like a million times.”

“Yes, of course.” The Earth Pony Guard bowed again and stepped aside to let Twilight through. Twilight told herself that she was not stomping into the room, especially not after a second guard had made to stop her but had halted when he saw the first guard silently motion to let her pass. Now that she had finally made it to Celestia she thought that the worst of the day would finally be over. She would be with her teacher who would be happy to see her and in Celestia’s shadow she would not have to worry about being ignored because everypony looked up to Celestia.

The moment she pushed her way through and could fully see Celestia deep within her Twilight knew she was wrong. The worst was not over. The moment she bore full witness to Celestia’s majestic, divine form a hundred thoughts wormed their way to the front of her brain. Twilight was analytical, she could pick out any and every detail be it a typo in a book or a bit of color drawn over the lines. It was her double-edged sword, because she couldn’t help but pick over every single detail of Celestia’s figure and compare to herself.

There Celestia in her royal attire, a white dress hemmed and patterned with the colors of the sun and Celestia’s sun. Twilight wearing a simple pair of pants and a sweater-vest.

Celestia was much taller than Twilight, taller than any pony in Equestria for that matter. Its why the majority of the ponies in the room had their eyes on Celestia and not on Twilight because their necks were drawn upward by her looming presence. Her wings were large and full, easily capable of spanning fourteen feet in length when spread apart, while Twilight’s puffed out just slightly beyond her shoulders as if they had been glued on. Her wings were not the only thing broad about Celestia, so was her body while not being as overly muscular as the guard outside her shoulders stretched from side to side wide enough that she sometimes had to turn and shift to get through normal doorframes. Even then it was struggle because the reason why her shoulders were wide was to support her breasts, which she had once heard referred to as ‘the bountiful mountains and deep canyon of Equestria’. Twilight unconsciously raised an arm to cover her own chest which were ant hills compared to mountains.

Twilight’s cruel analysis was not over yet. While Twilight’s own stomach was relatively flat and plain, Celestia’s rolled out ever so gently from her body. A legacy of the all the sweets Celestia loved to eat. Just below Celestia’s stomach her curves became metaphorically dangerous, Twilight’s thighs were like fry sticks compared to Celestia’s turkey drum legs. Not only that but Celestia’s thighs and hips rounded out to the perfectly, bubbly shaped ass that always swayed ever so rhythmically with each of Celestia’s footsteps. Twilight’s mind had just been about to compare Twilight’s nigh-non-existent rear with Celestia’s but she was interrupted in her off the rails flying train of thoughts. Her body had moved mechanically forward through the crowd, she had left them behind and stood only a few feet from Celestia who smiled and looked down on her former, faithful student.

“Hello Twilight, I hope you did not have any trouble getting here.”

In that moment. A tiny part of Twilight’s brain had a thought. A jealous but needful thought that wanted to be heard oh, so very much.

I wish I had Celestia’s figure.

In Twilight’s ears she heard claws, or perhaps finger paws, snap.

An explosion of light filled the room as two coronas of magical energy erupted around the figures of Celestia and Twilight Sparkle. Energy blasted air throughout the room throwing over everypony except Celestia and Twilight who stood at the center of the swirling magic as if they were in the eyes of two different hurricanes. Neither could see each other through the storm of magic, they were barely able to open their eyes from the brightness of the magic but they could certainly feel the magic’s work.

For Celestia it was more of a woozy feeling, a wave of nausea followed by a sudden drop. Her dress, tailored for a formerly much larger mare slipped past her shoulders and fell to the ground. Clenching her arms and legs together stopped her bra and underwear from following her dress to the ground but the straps hung limply against her sides.

For Twilight the magic’s work was quite the opposite. It seemed to take its time with her and she felt every moment as her body stretched and burst outward. Her frame trembled as she felt pounds of fat, muscle and flesh that had not been there before fill into her. It seemed all of the changes to her body competed to happen all at once.

She felt as her body frame rose taller and taller still, her shoulder blades ached as her shoulders pushed out to either side of her. Her sweater vest stretched loudly in her ears as it tried to contain the sudden shift of Twilight’s body. Thick arms with muscle overlaid with soft fat burst through her sleeves around her biceps, the sleeve cuff of her vest traveled up her arms as they lengthened and burst at the seams close to her elbows. Bits of her mulberry colored coat poked their way through widening holes around the back and shoulders of her sweater vest but what really did it in was her chest. Her petite breasts swelled, the feeling sent a shiver through Twilight’s spine making her jump in place several times, each time she caught sight of her breasts filling out as they a size larger and larger. Her bra snapped first beneath her sweater as all over her torso the pressure of the material tried to constrain her body, stinging her sides even as she was mesmerized by the ballooning of her chest. As further holes appeared over an unfamiliar valley of cleavage in front of Twilight she caught sight of an engorged nipple poke its way out from underneath her sweater. Twilight would have thought more on why her nipple looked to be plump and aroused right then if she had not been distracted by her sweater finally tearing down the middle and let her breasts hang free.

Twilight let out a sigh of relief but had to suck in her breath once more as her pants dug into her waistline and pressed in all along her legs. She tried to move one of her legs but stopped and blushed as a loud tear echoed in her ears. She felt surprisingly cool air crush against her thighs and over her womanhood. She strained to look down around her to see as the top of her thickening thighs and fat ass squeezed over the top of her pants, the supple flesh spilled out above the waistline of her pants before her pants too were destroyed. It felts extremely liberating to Twilight, making her bite down on her lip as she flexed her powerful thighs through the last shreds of her pants and bulge out. Swaying even slightly she felt the weight of her new ass throw her off balance so much that she had to catch herself from falling over. Despite her pants being in ruins below her she still felt an oddly pinching sensation around her waist, she reached down and brushed her hands over the barest strands of her panties. She licked her lips as she felt the last strands of her panties rub against her vulva and between her flanks before they too snapped and hung limply between Twilight’s thighs.

Twilight also noticed her hair lengthen, the flesh on her back shivered as she felt the strands of her hair slide down her back, surprisingly straight and even, until her hair just reached the base of her tail. Her puffy wings stretched and she flexes them as they bent into a longer, more regal shape. She marveled as she flexed entirely new rows of feathers, extending her wingspan upward as if she was stretching her arms after a nap, her wings went up and up, the ceiling had to be twenty feet tall but Twilight felt she could just about touch it with the very tip of her wing feathers. She brought them back down to a resting position, she felt slightly doozy from that display and barely had time to compute the changes on her body when the magical energy changed color and exploded in a thick cloud of smoke.

Twilight of a few minutes ago would have been knocked off of her feet but the Twilight of now was much sturdier. Quickly finding a stable balance for her body she braced against the last gust of wind from the end of the magic, standing tall and unbowed. Her eyes and lungs however were affected by the smoke and soon she found herself coughing on the smoke and also her eyes stinging. From the direction of the entranceway and where the crowd of ponies had been pushed to by the magical wind concerned voices called out and hooves rushed forward. Several armored shapes surrounded Twilight, for a moment her mind flashed with panic worrying they were going to seize her but the panic melted away as half a dozen guards turned and faced outward-spears pointed away from her. They had formed into a protective formation around her.

“Princess! Are you alright? You weren’t hurt, were you?” a guard asked as he trotted up to her.

“I-I’m fine.” Twilight coughed, as the smoke cleared she could see the guard’s shoulders drop in relief and the sides of his muzzle shift into a grateful smile.

“Thank the sun and moon! I don’t know how I would be feeling if you were harmed, Princess Celestia.” The guard said and saluted at Twilight. Twilight did not notice as she stared blankly in his direction and his words were ringing in her ears. He had called her Princess Celestia.”

“Is Princess Celestia alright?” another pony further off asked, the smoke was clearing faster and Twilight could now see the entranceway. Several dozen heads were looking up in the general direction of her body. They thought that she was Princess Celestia because they could only just vaguely make out the shape of her body in the smoke Twilight realized.

“Yes, it looks like she is unharmed. We don’t know who or what did this. We need to get Princess Cele…” the guard pony’s words died on his lips as finally the smoke cleared well enough for him to realize the shade of Twilight’s coat, the style of her hair and the features of her face. He looked from up at her down, slowly Twilight noted, to Twilight’s flank where her cutie mark stood proudly over her side. Twilight approvingly noted it didn’t look stretched or distorted in the slightest by her sudden…shift.

“Um, Princess Twilight Sparkle. You’re not Princess Celestia…” the guard said slowly, staring at her cutie mark. All around her, confused guards looked at her and had to double take as they looked her over again and again. Twilight was not sure what had to be going through their minds. That they had mistaken Twilight for Celestia. That they had failed to recognize Twilight. That Twilight was here at all. How Twilight looked now.

“Over here…” Celestia’s voice weakly drifted up from a patch of smoke soon followed by Celestia herself standing up. Twilight wondered where she had gotten the sheet to cover herself up with.

“Princess!” Twilight cried with concern and pushed her way past the guards to get to Celestia. She was surprised by how easily she shoved the two guards aside, each one who she could only see from the bottom corner of her eyes, were easily bowled over by her new strength. She was also surprised by how quickly she made it over to Celestia, in a handful of short strides she was looming over her mentor. When she fell down to her knees in front of Celestia she was still looming over Celestia, even if the floor trembling from Twilight’s impact made Celestia hop in place.

“Twilight, are you alright? What is going on?” as Celestia spoke Twilight also realized the sheet she had mistaken before was Celestia’s dress, it looked comically big for Celestia now. A part of Twilight did think that it did look just HER size.

“I don’t know, Princess.” Twilight looked down at Celestia with worry. Celestia looked so much smaller now, weak even. A part of Twilight also wondered if this was how Celestia viewed her normally. “Though, I think…I think Discord may be involved.”

“Not Discord!” Celestia sighed and made to rest her hand on her forehead. That meant however removing her hand from holding up her sheet. Celestia let out a squeak as Twilight caught a glance of Celestia’s naked, smaller figure. Celestia’s face burned brightly with a blush, Twilight made to ask how Celestia felt when behind her a guard beat her first.

“Discord? I had enough of his chaos magic when he turned Cloudsdale into a chocolate shake.” One of the Pegasi Royal Guards grumbled.

“Oh no, is he actually in Baltimare now?” an Earth Pony mare asked and shook her head. She looked to be one of the locals who had come to petition Celestia.

“Who knows what he is going to do next?” an Unicorn mare beside her asked also. Behind her the crowd of ponies mumbled among themselves, passing the word that Discord had been the one responsible for the strange magical energy.

“M’am! What should we do now? What are your orders?” Twilight was surprised when the guard asked Twilight directly. She noticed every single one of the guards had their eyes on her, not Celestia, waiting for orders.

“We don’t want to cause a panic. Let everypony known that Discord seems to just be pulling a prank of Celestia and I. Meanwhile, please spread-out and look for him. Once you know where he is report back here.” Twilight ordered, she had been in charge of Ponyville’s Winter-Wrap Up for years so she was accustomed to sending Ponies off to complete various tasks.

“I think we- “Celestia had begun to say, but was interrupted when one of the local bureaucrats. Again, they had ignored Celestia and had their sight drilled on Twilight.

“We still have a lot to get done before the launching of the ships later this week. Are we going to have to shut down the government?”

“No, I think we can still run things smoothly. I can handle any paperwork that comes to the royal desk.” Twilight replied, she looked around the room as ponies shuffled closer and began to ask their own series of questions. It felt strange to Twilight, as if some kind of energy in the room had shifted and Twilight was in the center of it all.

“Princess Twilight…should we find you some clothes?” a royal butler asked. His comment had everypony in the room do a double take or a series of exaggerated blinks, Twilight noticed. As they processed his words Twilight suddenly felt dozens of pairs of eyes shift and gaze over her body. Normally, she would have been immediately mortified by the stares and try her best to cover herself, but Twilight felt different this time. She challenged their stares, sliding her hands to her hips she stood taller and straighter, thrusting her bust outward. Twilight felt oddly satisfied as her posturing seemed to have a positive effect, most of the ponies blushed and shyly looked away immediately, some took longer than others and Twilight thought she could see a hungry or even envious glint here and there.

“Let’s also find clothes for Princess Celestia…let us also adjourn for now. We will pick up the court later.” Twilight ordered, and was happy to see her orders were obeyed. Two royal guards that had not been standing around her stepped around Celestia to protect and shield her body from view. Celestia made to say something but Twilight was already moving toward the exit, her ring of royal guards keeping others away from her.

Stooping to get through the doorway and with all eyes on her Twilight walked toward the royal quarters with long, sultry steps.
