Slowly Growing into Her Kingdom

Slowly Growing into Her Kingdom
B_25 & Dawn-Heart

The book perplexed her since she was a filly, one tucked in the sacred ward of the Canterlot Castle library, beyond the reach of her little hooves, the door protected by two towering pegasi clad in golden armour. They bore their arms despite the civil surroundings.

And Twilight Sparkle, with her limitless magical potential and vast intelligence gained from a sea of knowledge, who was allowed entry into nearly every restricted section, personally led by Princess Celestia herself in her personal passages, was denied of accessing that place where the forbidden tome belonged—there were few as old, but only this one struck within her memory after all these years.

The one book she was never allowed to read.

It never made sense. She'd always been a small filly, the kind lost in the shadows, literal and metaphorical, of the ponies around her, of the princess, of bookshelves and maybe even of the world itself.

Magic and intelligence compensated for the hollowness she felt. Friends and family and genuine accomplishments filled her emptiness with the foam of love and friendship. Even then, lurking within that fullness was an itch, a subtle aching of hollowness, of 'what if' and 'what could be' never leaving the brightest of minds to their current happiness.

“Twilight? Where you flying off to? Party’s THATTA way!” Twilight ceased the clopping of her hooves against the marble floor. She glanced over her shoulder, where the distant bundle of blue approached behind her. “Where the heck are you off to anyway?”

Twilight blinked. Should she lie? “Hey Rainbow. Any of the other girls noticed I slipped away?”

Rainbow Dash shook her head upon coming to a stop… below her. Twilight panged with strangeness on the need to look down for their eyes to meet. Becoming tall twitched her leg sporadic, a pleasant, heated pricking beneath her skin, and a swelling sensation… evoking from a part of her rump she didn’t dare ponder.

“Nah. You’re all good.” Rainbow glanced over her back as well. “Princess is still rambling about gratefulness for everypony and all that. The girls seem pretty caught up by it. Like usual.”

Twilight raised an eyebrow. “And you weren't?”

“None of this stuff really applies when you’re flying fast and taking names. Besides, watching someone talk is usually pretty boring anyway. Seeing you leave, however.” Her eyes squinted upon returning forward. “I don’t get it. Aren’t you always the one telling us to pay attention to the princess’s every word and sneeze?”

Caught. Body becoming hot. Don’t retreat, Twilight.

“Well?”

Twilight then giggled. Her nerves shivered beneath her skin. Purple skin pulling itself taut; breaths too broad to properly fill her lungs. Focus. Blinks twice and clear your mind. “Have you listened to the same lesson ten times over? I think you’re allowed some leeway after that.”

“Then where exactly is that leeway taking you, huh?”

Twilight sighed. Her hind legs buckled and her rump dropped against the ground, purple plushness filling out, the dense layer of squish of her flanks now elevating—if only slightly—the rest of her body. Even sitting she was taller! Rainbow stood, and even then, her eyes were still inches below her own… as she stood as tall as she could, too!

All to still be inches shorter than Twilight.

“Alright. You got me. It’s been a while since I’ve been allowed to explore the castle by myself, alright? Being a filly made that a lot easier, once upon a time.” Twilight gazed up to the long series of stained windows sprawling across the hall, each enriched with a fabled tale. “No guards escorting me. Not a servant bowing as I walk by.”

A heavy exhale. Closing of the eyes. A sad smile. “I just miss being a filly. That’s all. Allowed to wander all by myself.” Her eyes opened to Rainbow's face. She gazed at her hooves with her ears flattened against her head. “The girls or the party isn’t going to miss me for an hour. There was a time when I could just leave without being noticed, you know.”

Rainbow lifted her eyes with a smile. “How the unpopular have become important.”

Twilight chuckled. “Allow me to be unpopular one more time?”

The wind beat against the windows, whistling harshly, a subtle creaking appearing.

“Let’s make a deal, then.” Rainbow Dash held her foreleg out, slender and fuzzy, its delicate skin easy on the eye. “Enjoy your walk around the castle, and I'll drop out for a quick flight over the castle.” She playfully wiggled her hoof. “I cover for you, and you cover for me. We got a deal?”

Twilight smiled. She shook the blue arm—despite her arm easily covering over and around it. “You drive a hard bargain, Rainbow Dash.”

They shook.

“But thank you, Rainbow.”

“Why?” Rainbow laughed upon pulling back her hoof. “I wasn't here. And neither were you!”

The two separated. There wasn’t much time left. Other ponies would be quick to wonder where their newest princess had disappeared to. Time for quickness.

But when she reached the duel, towering doors, like slabs of wood lined with sprawling, golden handles, Twilight froze in place.

She blinked at it. Having to crane her neck back to see the top of the door, of the entrance itself. That itch above her flanks, burning beneath her skin, it ceased at once, and the hollow feeling returned. Twilight went to glance back and down the hall—but Rainbow as gone too, nothing left to feel bigger too.

Perhaps that's why Twilight sped through the library.

Her heart was beating in her ears by the time she reached the back of the library, where the towering bookcases lowered and lowered, leaving the area spacious. Again, when she slowed to a walk, Twilight's memory didn't fail her—two guards posted at the entrance to the section, bearing arms, dressed in gold, and now shorter than her.

Two elite members of the Royal Guard, the peak of what a stallion can be, dressed in the densest suit of armour, coming up only to her chin. They still scared her. Their bodies frozen, their gazes locked forward, never acknowledging her despite how openly she walked toward them.

She prepared a few more words into her mind, some lies to roll off the tongue, and when she came to them with an open mouth, Twilight watched their heads dip into a bow. “Princess, you desire access?”

Twilight didn't trust her tongue, or the trembling tucked within her legs, but a simple nod of her head, and the holding of her breath. Why was all of this so tense? There wasn't any good reason to be so nervous. All this place held were books and tomes denied to her before. Not only was she a princess, but she was also a hero.

Going to read restricted books wasn't an act of evil.

The guards didn't say anything, only moving apart, enough for her to pass in-between. And she did, feeling their smooth armour graze across her sides. Against the lower half of her barrel where the height of their backs reached at their peak.

Twilight walked through the thick brown curtains that covered the entrance, and she disappeared into the room, the shuffling of armour confirmed the guards closed into the width of her body had left behind. She went searching for the tome, of which only princesses were allowed to read, and for whom, it applied to.

Only three others had read that book, and all of them had denied Twilight the chance to do the same.

Even when she ascended, that book was never talked about again, and would keep that way—even if Twilight dared the courage to ask about it. She entered that room to retrieve that book, and when she left, with it tucked and hidden underneath the curling of her left-wing, she was never the same again.

The rain pelted against the window. Through the faded glass, down below it, Twilight sat hunched over her desk, reading what laid open before her. Her trance kept locked through the pelting. The cracks of thunder and the illuminating light of momentary thunder flashed the room with a brightness greater than the burning wicks of the candles. She read the page in the three seconds the light lingered, not trusting her horn, not a spark of magic while she read.

In fear of casting something by mistake, or having her progress tracked.

She was still wearing her dress from the Gala.

“Twilight?” Soft knocks came at the door. It was beyond midnight. What was he doing awake? “Are you awake? There's a glow coming underneath your door.” He sighed for a moment, a croak to his voice. Why did he sound slightly scared? “The p-princess said you shouldn't be staying up so late.”

His voice squeaked at the last word, and at once, he caught himself. “At least not as frequently!”

Twilight sighed. Shaking her head, it was getting late. “It's alright, Spike. You can come in.”

Her wing stretched over the desk as the door creaked opened behind her. The soft cracking of footsteps sounded from the crystal floor as she curled the tome against her side. Turning around in her seat, she smiled at the small dragon. “It's good you caught me, Spike. I might have forgotten to sleep if you didn't remind me.”

Spike stood afar. His lips trembled into a smile, but the glowing green of his eyes was more glossy than usual. They seemed fixated on her wing. The left one. The book held by the curled appendage. But he didn't say anything.

“Are you okay, Spike?” Thunder flashed the room, and a yelp followed a pitch above its cracking might. The scratching of feet against crystal was like tiny and consistent whimpers. Twilight blew out the candles at once, risking a soft glow from her horn as she came down from her seat. “You're not usually up this late, are you?”

“W-What? You kidding?” Spike laughed, and exhaled, and chuckled, and exhaled. “I was just reading comic books and, and...”

Twilight came to him and, uncurling her free wing, draped it over the small dragon. His smooth scales caressed her soft fur with every minuscule shake of his body. Spike didn't try to fight or to lie. He laid his head against the bottom of her belly—the highest place on her body he could reach.

Above her rump, beneath the skin, that hot spot itched again.

“You can cozy against me as much as you like, Spike.” His little body came pressing against her side, his head nearly slipping underneath the soft slope of her belly. Her legs almost buckled together at the thought of that; of Spike, standing tall beneath her frame, her four, slender long legs marking each of his horizons. Not now! “I know how much storms settle you. You don't have to act strong around me.”

Twilight smiled at the words that followed next. “I'll always protect you.”

Spike didn't have any words to say, but his head, rubbing up and down the side of her coat, was enough to send another shiver down her spine. Together they left the room, and as a duo, they went down the hall.

The whole way, Twilight glanced down her frame at the tiny dragon, wanting... more of him. Something spasmed close to her crotch at the idea of collecting more of him against her. To lay down on top of him, covering everything of his small body, smothering him in the softness of her lavender coat.

Twilight tugged some of her bottom lip inside her mouth, nipping on an inch of it, hoping her tension was going noticed. The book in her wing felt heavier. Enough to make the appendage ache. But the feeling of Spike pressing tightly against her side diminished the sensation, but at the same time, making her wish her wings were slightly bigger—if only to scoop her dragon into it, and held him tightly to her side.

“Do you think you'll be able to go to bed by yourself?” Twilight almost wished the answer was 'no' so she could curl her body around his, holding him tightly to her barrel, indulging in the sense of covering all of his body with some of her own. “We can share the bed like old times if you're feeling up to it! We don't have to tell anypony if you don't want to.”

But Spike shook his head, taking a step back, all while holding up a claw. “No way, Twilight! Just because I'm afraid of some storms doesn't mean I need to be cuddled to sleep.” His cheeks burned pink as he then turned away. “I appreciate the offer, b-but I'm way to old for that now.”

Twilight's shoulders went slump. “You sure?”

“Positive.” Spike went for his door, laying his claw on the handle. “Now you get to sleep as well.” He pulled the door back but then pausing. “I... really don't want to wander the halls right now just to make sure you're not awake.”

“I'm not going to make you go chasing for me when there's a storm, Spike.” Twilight turned. “I promise I'll be in my bedroom until morning.” She blinked. “Maybe late morning.” She laughed to herself, then started to walk. “That should give you plenty of time to cook and bring me breakfast in bed.”

“Har-har.”

Twilight didn't go to sleep. Not when her mind spinning and her body was itching. She came onto her bed and laid back against the series of pillows, uncurling her wings over the sides of the mattress, feeling them reach just to its edges.

The book laid among her feathers.

“It's about time we give you a proper reading.” The book levitated into the air inside the centre of her aura, its pages opening to the half mark while it floated to her muzzle. She didn't bother reading the page. It was the spell she was stuck on. “It's you that's giving me the problems, aren't you?”

Twilight blinked at the symbols. Written and drawn in faded, black ink—but each line, each broad shape, burning in a flurry of glowing greens and burning blues and violent violets. Twilight's mind couldn't comprehend the language, but her magic resonated with prismatic flames.

But should she cast the spell? The tome itself didn't bear a title and written in a collection of archaic languages. The only written account of the properties of alicorn power—what its energy was, how it surged and welled, how it was used and how it worked, its compounding effects—by an alicorn that never lived.

At least in the eyes of history.

Twilight knew she should have stopped reading the book after the first page. That she was still a new princess learning her place, learning her power, learning... wasn't this book a step in the right direction then? No. She didn't yet have the knowledge or respect of what she currently was, and this book could lead her astray.

But... what harm did knowing what made up the components of an alicorn were? Sure, this was dangerous information in the hooves of someone other than the princesses. But Twilight was a hero! Her head nodded at this fact, while a vibrant green singed across the contour of her glowing sphere of magic.

And it was just one spell for experimentation! Twilight rolled against the comfy, frilly blanket she laid atop of. How else was she supposed to learn more about the text if she couldn't yet understand it? Perhaps this spell would reveal something to her; maybe this spell would unlock something ancient within her ascension.

Blue consumed the mass around the centre of the magical sphere. It came dimmed, but the centre of the aura pulsated, waves of ripples coursing through the field of magic, brightening the green and the blue into shining heights.

Twilight curled back her head while her body was lifted into the air, arching into place, while violet truck the centre of her magic. She screamed with lips bit tightly together to repress the wailing of her body. Hot electricity surged through her body, vines of growing thickness rewiring her veins, pleasure and pain mixing into a horribly wonderful paradox.

She couldn't stop the trembled that rocked her body, or how the spasm spreading her hind legs apart, the mass of her ass weighing her body back to the bed. Twilight groaned and clenched her eyes, struggling to slip her legs back together, riding out the jolts raised and dropped her belly in the air.

Steam welled underneath her skin. A bloating sensation expanded from her rump and lower body, while the tingling electricity coursed up and down her legs, in and out her wings, everything surging from her horn, its tip pulsating further and further away until it no longer felt attached to her body.

Twilight gave a final cry while biting on the interior of her cheeks. The pain slowly transitioned into a horrible aching, a stretching that touched upon the sensation that welled close to her crotch, a tightness constricting itself... biting itself... welling into itself... past the folds of her hidden pussy.

The spell dropped Twilight back onto the bed as the spell snapped out from existence. Embers of green and blue and violet lingered in the air and illuminated the bed like fireflies. Below, strands of mane covered Twilight's eyes, and the steam of her breath could be seen even in the warm bed.

And every inch of her body was tingly.

Twilight moaned as she rolled, letting the weight of her body press into the bed, trying to snuff the millions of little sensation poking at every inch of her body. A heated massage carried on inside of her body, the fat of her flanks pricking in a gooey expanding feeling, the length of her legs warming in a dripping kind of way.

All of these feelings, the warmth and the goodness and the bliss, all of it filled everything beneath her body. But it all concerted from her crotch. The tight little pussy of purple tucked beneath her golden dress. How could Twilight feel so big, her body so wiggly and growing, while her pussy shrunk and tighten and dripped?

“Mmmhmm!” Twilight gazed down the length of her body, the different glow of colours illuminating her frame. Her skin burned through the fabric covering her; none of it even felt like it was there. “W-What's... nnnghnnn... wrong with... me?”

Thoughts should have come. Worries plentiful. But none were on her mind. For once in her life, a strange calm, a pleasant emptiness washed over the field where thought brewed and welled and bunched together. Twilight was strangely hollow in all but one coursing sensation—the growing pleasure that heated her body. Her every softness melting underneath its contact.

Her hoof weighed down on her chest. The limb was suddenly hard to lift as it coursed with pulsating goodness. Biting her bottom lip, Twilight suppressed another moan while her hoof traced circles into her frame. They sunk and melted into her, the two strikings of fires that melded together into a euphoric-like inferno.

“H-H-How could simple contact—yaaaaawl!—be doing this!?”

Twilight tensed again against the second assault of numbing pleasure that rocked through her limbs. Once more, her flanks clenched together, feeling as though they meshed and bounced off the other, while her pussy twitched, shrinking, that horrible tightness tingling again.

“P-Please! I... c-can't take much more of this!” Twilight rolled onto her front while her body quiver, every curve to her body melting to the heat of her pleasure. Her chin planted against the top of the pillows while beads of sweat coursed down her face. She opened her mouth, biting into a cover. “Mmhmm.... nnnngnmmm... mmmm...”

The rocking of the seas changed into slowly lapping waves, ones that raised her body from her flanks to across her back, jolting her head into the air by an inch. Instead of rocking, the waves beneath the skin caressed, massaging what had melted back into what it was, though this time, loosened by pleasure.

Twilight closed one of her eyes, the slick strands of mane covering it anyway while her hoof searched down her body. Now she was able, on shaking hind legs, raise her heavy ass into the air, feeling, almost like a phantom, a soft weight to each of her flanks. “Nnngh... but... why?”

Her hind legs closed again and against the tingeing of her pussy. It felt on fire—but in the most cooling sense possible. Twilight could feel her walls undulating, welling off each other, trying to starve away the horrible itching sensation.

A single touch, one right thrust, and everything in her pussy would melt into lavender goo. Her thighs pressed tightly together to repress the euphoric sensation. Like a horny mare in heat, the front of Twilight's body fell gently against the wall of pillows, her head turned against them from below, staring at her ass up in the air.

It took some effort, a little bit of will to raise her hoof of bloated heat and pleasure into the air, her bones too weak to hold something so full. But that trembling hoof stretched the in space underneath the expanse of her belly, and though it didn't make much sense to her half-alive mind, she reached for the back of her dress-clad rump.

“I... should... back up my legs...” Doing so was an impossible task when all of her body felt ready to collapse. But the very idea of losing it now, while her body ached and welled and burned with pleasure that not even the depths of her mind could comprehend beyond the numbing effects of it all... no! She couldn't be left motionless on her bed, not when her pussy clamped and tightened and shrunk, begging, pleading all to be touched but once. “P-Please... just let me... please...”

But Twilight's hoof crossed the arched between her hind legs with relative ease, which made her eyebrows arched at the effect, though they quickly shot up at the first contact. Through the fabric, the definition of her plump pussy was clear against her hoof, the same size but feeling infinitely more delicate.

And sensitive.

“Aaaugh!” Twilight cried and whined when her mind nearly blew with the divine feeling resonating at the entrance of her pussy. The individual strands of the purple fuzz of her vulva stood like flames burning against her dress, and each press of her hoof against them sent that undulating heat into her tightening tunnel. “M-More! Oh, please! Just a little more!”

Twilight had given up on being heard, but the strikes of thunder, flashes of lighting concealed her throes of pleasure. When the bolts came, they seemed to come in colour. The raging winds outside didn't so much crash around the castle as swirl around it.

Twilight clenched her eyes at such thoughts, pleading with not her mind, but her horn to bring back the feeling, the sensation of perfection. Slowly, the heat against her lax muscles, the bloating in her softness—all of it faded, slowly, while the itching, aching, and painful burning remained.

Which the glowing of her horn, and the burning of the spell, then quelled.

The spell burst again. Twilight's eyes opened to the floating embers not only lurking over her bed but well beyond it. Not that it mattered. Not when strokes of electric flames coursed from out of her pussy again, a leaky kind of hot wetness spreading throughout her frame. She was getting wet from the inside out, a release of liquids but with none somehow spilling out onto her dress.

Then came the sounds. The sweet melody of thin fabric tearing slowly, the developing slit splitting down the crotch of the dress, the bursting of her flanks through the padded back, jiggling the momentum away. Twilight bit her bottom as the tearing sound persisted, it tickling something deep within her pussy, beating down on that itch with a waterfall of pouring coolness.

Coolness and freshness. Twilight's tongue dolled out from her mouth while her eyes rolled up. An influx of cool air swirled against the heated skin of her ass, the coursing flames beneath the fuzz of her vulva. It tickled her. Relieved her. Sent a gust of something cooling within her constricting passage, alleviating some of the billowing steam within.

Twilight was breathing. Her chest rising and dropping in tiny increments. She felt so cute, her body so desperate, pleading to be free from its cursed arousal. It wasn't often she thought of her body as much as anything, but now, she was the sexy, needy, purple alicorn that needed to be fucked.

Her tail raised higher into the air, and by the trick of the mind, draped lower than it was supposed to. She didn't bother with her hoof. Letting the heavy weight of her bigger frame win out, Twilight rolled to the left, collapsing onto her back, with her wings already uncurled out.

The tome laid underneath one of her wings, dropped from the spell, and nearly forgotten about.

But Twilight didn't care. Not when she needed to be touched, caressed, pleased. Her soft little hooves came down onto her slender front, one searching in circles across her chest, the other dipping into the plushness of her belly, inching, little by little, to the aching pulses resonated from her engorged clit.

“Mmmhmm... yeeeeees!” The first touch was the first strike of lighting, of pure arousal energy surging outward into her body. The softness at the centre of her hoof matches the fussiness of her cute little clit, which winked in need, pulling on her skin. “Like that. Aren't I... just a naughty girl. Stealing books. Using restricted spells. W-When did I become so... s-sexy!?”

Twilight didn't mean to do it. But her wings slapped the bubbly textures of her flanks, the sharp slap pleasant to her perked ears, a whimper of pleasure escaping her lips, the tips of her wings clinging to the large slope of her curving ass, retaining that burning sensation to linger for just a few seconds longer.

It wasn't before long that Twilight had enough. Her wings let go of the supple texture of her ass, which, when her wings pulled away, felt like they jiggled back into the bed. But surely she wasn't that big. Didn't matter. Her wings went were her body demanded—the shrinking, heated place, that was tucked inside her pussy.

“Please! Like that! More... more... more...” Twilight spread her pussy open with one of her wings, keeping it held back, while her other wing dipped its tip at her entrance. The feeling of something entering her tightness was electrifying—her hips arched into the air, her crotch barrelling into her own wing, feeling it penetrate only an inch inward. “Not enough... not enough...”

Twilight kept her back to the bed and her ass in the air, flicking her hips, fucking her pussy with the tip of her wing. It wasn't long, and it wasn't hard. But the fucking of her sensitive entrance, of her tight walls being pushed apart, made everything behind it clench tighter—her hoof flicking her clit in tiny and quick circles to milk to overriding euphoria that threatened to burst the welling wetness tucked with the depths of her overfilling pussy.

It came. Never like this and never this easy. Hooves were meant to tease Twilight's entrance, to feel the smoothness of her sides, the soft curves of her hips, the plushness of her chest and belly, to play with her clit. Her wings could start her out, opening her pussy and getting her wet, but never had either of the two been enough for her head to whip right and left against into the pillows, screaming into the roars of thunder at the release of orgasmic bliss.

But a few touches, all without tools and magic, caused her pussy to clamp and clench and well, while her eyes shut and her mouth closed and whimpers and moans and groans and screams threatened to mix into one wailing sound. Her hind legs swung together at once, thick thighs clinging to make the intense sensation linger for a few seconds longer.

And then the torrents of marecum came splashing out. Hot streaks of warm liquid splashing against the curving purple of Twilight's thighs, which then fell apart, spreading, becoming lax while her exposed pussy gushed freely with the milky white arousal.

Twilight knew her scent. While the back of her head rolled against the pillows while she rode out her orgasm, letting a wing massage into the globe of her right flank, and a hoof trace lovingly over the front of her barrel, the dense sweet musky scent filtered into her snout. Strong. Overpowering. Everywhere.

She'd never stink up her room with the smell of her pussy before, baking it in her scent, feeling it permeate by the second. Worries for another time, however. Twilight flicked her hips every now and again, indulging in the bliss of squeezing the last trickle of cum pour from the base of her pussy, feeling her sex-deprived of that horribly wonderful feeling.

It took moments. Perhaps minutes. Lying. Breathing. Maybe relaxing. Her eyes glowed a soft hue of purple in the darkness of her room, the only source of light. While she heaved, Twilight looked around, the embers of colours no longer around. The pelting of rain had slowed, the thunder gone, lighting ceased.

Twilight knew she should have thought more about all of this, that she should have picked up that book and not stop reading until every page was done and understood. Something had happened. Happened to her.

Something had changed.

But Twilight couldn't will herself to stand, or to move, not even to cast a spell to clean her mess or take off her dress. The glow of her eyes disappeared underneath the closing of her lids. The thick musk hung over the room, but instead of feeling guilty, of being dirty—Twilight felt like she not only owned the place.

But that she dominated it.

Last night didn't feel real.

Twilight kicked her hooves like a cat trying to swim in a bath while the warm blanket of sunlight warmed up her skin. Intransitive as too no amount of shutting her eyes could repress, but pleasant enough in how heated her skin.

Especially... down there.

Twilight blinked eyes, only twice, and kept them open. She shouldn't have been feeling any heat down there. Her eyes narrowed as a response. Blindly, she slapped a hoof onto her chest, the dense fabric padding the softness of her chest—soft purple strands tickling her back.

Feelings of being a slob for sleeping in her dress surrender to the confusion of why that dress was torn. Crumpled and with wrinkles, sure, but not ripped and torn. Twilight's hoof slid down to her belly, feeling more, tight slits with tiny tufts of her purple strands.

Rolling around in her sleep wouldn't have done something like this.

Twilight felt her lip quiver while her hoof touched her body. Memories of the night before—an abstract dream mixed with intense, but vague feelings—caressed in that tingly way. Currents of wetness below her skin, tiny and round, overflowing.

Now's not the time, Twilight thought to herself while her hoof continued its search, denying the tickles of pleasure as her hoof felt everything supple about her. Come to think of it, her body pressed out against the dress, slightly, in a way that it hadn't before. That can't be right. D-Did I... put on some weight?

The hoof travelled down the smooth slope of her crotch, feeling, with a dry but some-what sticky texture, the clues of pleasure that had assaulted her last night. Twilight sat up in the bed while she examined herself below. The sides of her thighs spilled out through the open tears, both covered in patches of thin white.

“No, no, no!” Twilight breathing dived underwater and refused to come up. Memories projected faintly onto the theatre inside her mind. Ones of breaths, both laboured and quickening, joined by little whimpers, squeaks and tiny screams. Hooves searching over her body, caressing her curves and travailing across her soft slopes. Crazed movements, sure, but not the dress ripping kind. “Mirror! My mind is playing tricks on me—all I need is a mirror!”

Twilight knew she was talking funny as she got out of the bed, and when her hooves clopped against the ground, they did so in a smack, a barrelling impact—the kind when one meets the ground quicker than they were expecting. But why would habit betray her now?

“It doesn't matter! My mind just playing tricks on me!” Twilight danced on stumbling hooves across the ground of bedroom, swaying to the right, stumbling one too many steps to the left, her centre of balance non-existent. It was there... but even it was confused. “That spell. It must have... changed something. My body? No.”

The ground came rushing at her while her forelegs crossed and locked. Twilight fell onto her side, exhaling the dust of her floor while she laid still for a second, groaning and struggling the stand the next. With her legs bent back, she crawled awkwardly across the floor.

None of this is making sense! Why... am I crawling better than how I walk? Twilight noted her sense of balance returned while she crawled, the world around her the perfect height, her legs the perfect length. Something was different; something wasn't right. Doesn't matter. Just get to a mirror. Everything will be better once you get to the mirror.

Nothing was the same.

Twilight crawled to the mirror on the ends of her forelegs and, upon seeing her reflection through the glass, finally found the fiery breath exhaling coldly through her lips. Tension and fear of what could be released by seeing it before her.

Twilight blinked. It wasn't hard to see, but the bumbling of her mind made it so. One breath. Two breath. Three. Get up on your hooves. Stand tall. Relax. Close your eyes and breathe again, and this time, don't hold your breath when you open them back up.

“It's...” No words could summarize what she felt, staring at the standing mirror. It held her image—or as much of it as she could. Before, the glass could hold her frame and her horn, all of her size and most of what she wore.

But now, it struggled to keep her within its reflection.

Twilight stepped toward the mirror with a raised foreleg, and once she was close enough, pressed her hoof against her glass—if only for the smooth feeling of it against her skin to confirm that it was real. Even if everything it showed felt unreal.

There weren't any more words to be said. Twilight took a moment to examine how she looked. She felt... bigger. Longer too. Everything about her was different, totally changed even if only in a small way.

Her eyes studied her frame. There was no doubt gaining the pair of wings caused her to bulk out slightly, expand really, not so much in fat but in more of her. But now there was more, a tiny bit around her whole body, something a squint of the eyes to someone else could tell—but it was there, even if it was only minuscule.

“That's really me.” Twilight gazed down at her chest, at the tufts of purple spilling out—the strands reached further, shone a silky pure over their length. Fuller. Fluffier. Somewhat... sexier? “But I also can't hardly tell.”

Maybe she couldn't. If she blinked her eyes really quickly, her dress disappearing and the memory of last night faded, then maybe, facing the memory again, she wouldn't have noticed the difference. But that tick would be there. The strange sense that something was different. Small things caught to Twilight. The kind of things nopony else gives a second thought to.

That fear. That horrible confusion swelled with anxiety spilled from her body, like air spilling through a small tear. Twilight turned her body to the side, her eyes searching across her bigger frame, letting them glance wherever they pleased.

Tinged curiosity replaced all that fear.

There was something different about her legs. Twilight never really thought she had the knock out pair—they did the job of walking, running, jumping and sometimes limping. They weren't tall like Princess Celestia, stretching beauties to be admired at the back of the mind.

But as for Princess Candace...

Twilight found herself walking back and forth in place, watching how her legs rose into the air, higher, maybe an inch than usual before clopping down onto the ground. Her heart swelled and fluttered. A breath caught in her throat released by a single giggle.

Her legs didn't stride—they gave a full-blown show of their own.

“Oh? What's this?” Twilight laughed to herself as she swung her backside around to the glass, delighting in the small, weighty bounces of her flanks. That bubbly feeling, globes of purple swinging around slightly, tickled Twilight in a way she'd never felt before. “Another thing that's different.”

Something screamed at the back of Twilight's mind while she admired herself. A voice whispering something was wrong, nothing was right, and that now was the time to panic. It flooded in slow currents nervous energies meant to snap her out of this.

But Twilight was in a trance in studying her butt.

It wasn't something that had interested it before. Aspects of her feminine sexuality were but afterthoughts to magic and friends and books and duties. Not that she had much back there worth the examination.

But now?

Twilight laughed on drunk giggles while she swayed her backside, indulging in the bliss that came from feeling her the drops of her flanks while she moved. They never had weight before. She wasn't like Rarity, where every stride risked everything jiggling about. Twilight would have to jump and rock for the tiniest reaction—now the tiniest action out of her made her ass drop.

And while her eyes watched the swaying of her purple moons in the mirror, they also flicked up to her face, her lips curling into a small smile at seeing her head nearly at the top of the glass. But her horn wasn't within the frame. Even lowering it only brought some of it into the reflection.

Twilight stopped shaking her ass at that.

Now was the time to turn back around and study herself again. Twilight's eyes squinted, trying to make sense of it all. To no get too drunk on the tiny changes she'd taken to too quickly. She bowed her head, lowering her horn, feeling its tip trace across the glass.

Twilight blinked at her one eye in the reflection. Bringing a hoof to the side of her horn, she felt across its surface, the slender sensation touching her hoof, how its barrel had tightened together and its length tapering further out.

“That book.” Twilight didn't take her eyes off her reflection, her eyes still set on her body. She gazed over her changes, again and again, noting them, debating them, feeling them. Half of her suppressed screaming; the other half starving off the influx of euphoria. “It's the spell. It made me... grow.”

Those words felt neither good nor bad leaving her tongue.

“None of this should be hard! So why isn't any of this working!” Twilight fought the urge to spit at her own reflection, never hating an image of herself more in her life. She leaned heavily into her forelegs before the mirror, with a face that was narrowed, her eyes alight in violet, the tip of her horn glowing slightly brighter. “I am Twilight Sparkle! If I could crack Star Swirl the Bearded's spells, t-then this should be... a piece of cake!”

A tiny ball of violet swelled at the tip of her horn, the surface of which was electric with golden bolts, expelling a current of wind around it. Clenching her eyes, Twilight's head rolled down from its growing weight, barely suppressed groans escaping her lips. The electrical surge charged deeper into her horn, swelling and growing with energy—all of her quivering legs were too weak to uphold.

“Nnngh!”

Twilight slipped from the weight. The unsteadiness of her now long legs twirled from the kickback of the failed spell. Her side hit the floor. The ground rumbled and a thud rang out. Twilight's face was contorted in hollowness; violet strands of mane covered her bottom eye.

“This shouldn't be happening.” Whining wasn't like her—but neither was book stealing or growing. Lifting a shaky hoof into the air, Twilight then pressed it against the floor, her foreleg wobbling while she lifted herself in the floor... only for it to give out, and for her to crash back into the ground. “Casting that spell was easy. S-So, why am I struggling with it now?" The stringing threat of tears nipped at the corners of her eyes. "Celesta's sake, I was t-t-touching myself when I first cast it!"

Those words, upon uttering them, rendered the less of an accomplishment.

Twilight let herself linger on the floor, not sure what was left to still be done. It was a matter of time before she would have to leave the castle. A week without contact, without the words of friends or a letter from the princess was wilting at her soul.

But leaving the castle meant ponies would see her, and without a doubt, they would notice her growth.

That the princesses would quickly find out about her threat, that her worried friends, noting her disappearance, would barge into the castle looking for her.

Maybe. Just... maybe, if Twilight played her height off it wouldn't have been that big of a deal. There was no reversing the spell—at least not currently. But maybe the girls wouldn't notice she was different. Even if they did, Twilight had a good lie to fall on. She was an alicorn now. Perhaps her growth had yet to finish.

But they wouldn't buy that now. Now that Twilight's friends were worried for her, they were also more suspicious of her now as well. Before she could play it off. Now, the girls would be searching for every little thing about her just to see what was wrong.

“Why did I even do any of this in the first place?” Twilight groaned to herself upon placing her other forehoof against the ground, both of her legs shaking as she lifted herself into the air. She stumbled into place, and once more, was staring the purple mare in the glass. “I should have known better than to cast that spell. So why did I do it anyway?”

Twilight stared at her reflection a second time, she how her face covered the tightness at the top of the mirror, and of how everything above the base of her horn disappeared off the frame—and the same true for everything beyond the sides of her cheeks.

“Hopefully it's late enough for a walk.”

The streets were empty, and while Twilight walked them, wondered when was the last time she had done so.

But she needed to get out of the castle. Away from the same crystal halls, the boring rooms, the lack of fresh air or pleasant company. Spike had been given the week off due to 'an important project' she had to deal with. Starlight had gone off with Trixie for some kind of series of shows.

“Evening, princess.”

Twilight blinked while she walked, only now noticing the couple passing on her right through the cobbled street. Quickly, she smiled and nodded in response, not trusting her voice to not squeak when she spoke.

She did her best to keep carrying forward, but even as she did, her eyes glanced right to the windows of a passing shop. Her gaze caught that of the stallion's head looking back over at her shoulder, his eyes squinting, eyebrows slightly arched.

Did he notice something was different about her?

Then the mare on his side turned her head at once and, upon clocking his gaze, slapped him on the cheek. His mouth opened quickly, and it seemed like words were escaping him quickly, but the mare huffed and turned up her head, walking swiftly, causing the stallion to chase after her.

Twilight shook her head. Too close of a call! Could play off her alicorn growth rendered her taller than what most ponies were expecting? No. That lie only covered for so much and worked for so many ponies.

That was the reason why Twilight took away from the streets, in the direction of the woods along Sweet Apple Acres, but never daring to come close enough to be spotted by the average worker. In but mere moments, damp grass tickled the underside of her hooves while a faint, constant breeze caressed her back. Her tensed muscle relaxed, and the stumbling of her long legs slowly transitioned into resembling walking. on her hooves tickled her body with a breeze, her steps becoming more natural and assured.

Maybe she could get used to it.

“Y-Yo! Wait up! Twilight!” Twilight shivered at the sudden voice and dreaded what it meant. Her head whipped around for its source, eyes gazing across the open, dimly lit field. “You blind? I'm up here and comin' in close!”

Twilight tilted her head back, feeling her heart sputter when she did. Rainbow Dash appeared before her in the air, the slow flapping of her wings lowering her to the ground, her blue hooves touching down on the lush grass.

Twilight tilted her head again, only this time, downward. Rainbow stood at the middle-half of her chest, forced to crane her neck all the way back to stare up at Twilight. She was like a mare in the body of a filly, with all her mature features still there, but sill just so small to Twilight. She felt towering and commanding and authoritative. Even if that 'filly' was the great Rainbow Dash.

“Whoa, whoa, whoa!” Rainbow Dash stepped back from her, shaking her head while she did so. Something ticked her off. A subtle sense that something wasn't right. “What changed? Something's changed. What did you do?”

“What did I do?” Maybe it was the stress of worrying about being caught—or maybe actually getting caught itself, but Twilight felt a strange sense of humour wash over her at the moment. While Rainbow took a step back, she took a step forward. “I didn't do anything!”

“Nuh-uh.” Rainbow's eyes went wide. She must have realized she was backing away. This time, she kept still, tall as she could—her gaze reaching the underside of Twilight's barrel. Celestia, she could be tucked underneath there with the soft, purple belly used as a blanket to cover her. “You're pulling my hoof here. Something's up. You'd better spill it now.”

Twilight wasn't sure what she was supposed to say, what she was supposed to do. It'd been at least a week since she last saw anypony—much less talk to them. Her mind bumbled for excuses only for none to leave her tongue.

“Wait just a second.” Rainbow took a few steps backward in the grass, shaking her head while she did so. Her glowing pink eyes settled up, an inch higher than usual as she gazed up at Twilight. “No frickin' way... y-you got taller!”

“I didn't get taller!” Twilight sat on her rump and stuffed her hooves against her mouth. Rainbow arched an eyebrow—calling her bluff. With a sigh, the purple hooves fell away from her lips. “It's just that, uh...”

“That, uh, I got shorter?” Rainbow blew air through her lips while rolling her eyes. “Get real, Twilight. Listen, I get that, compared the rest of the girls that I can be a bit of a small fry—especially when it comes to you.” She pushed her muzzle to the side, peering up quizzically at Twilight. “But there's no way I got shorter.”

Twilight had to fight herself from breaking down right then and there. Rainbow had figured her out. From all of her friends, Rainbow sniffed her out from the start—and without having to try. What chance did she stand with everypony else? Or even the princesses?

“It's hopeless, isn't it!” Twilight's head hung forward while her eyes suppressed the familiar sting of tears. It seemed so strange to be caught so early, but repressing everything, letting it fester with every pulse of her stress... it had reached an unbearable pressure in her chest. “I-I was casting a spell when I started to grow a few inches! I didn't even realize until the day after! I was using a spell I wasn't supposed to, but I didn't mean to, well I did mean to, but, but...”

“But what? That your butt got bigger?” Those words stole a few blinks from Twilight while her head whipped into the air. What had she just said? The first sight was of the side of Rainbow's muzzle, and her grin was stretching apart it. She looked amused—an amusement bordering on amazement. “If the whole reason you've been ditching everpony is over something like that, well, I'm not exactly sure what to say.”

Twilight finally followed her gaze. Her head turned awkwardly over her own shoulders, eyes gazing down the long expanse of her back to the twin delights that laid on the ground below. Her two, fat, plump flanks welled out in the air, flatten somewhat over the land, covering more than just a patch of grass,

Every spade, of which, tickled the furs of her sensitive ass.

“R-Rainbow Dash!” Twilight contorted while grabbing at her rump, feeling the need to groan at it holdings its hefty weight. She hated it. How heavy her flanks were to hold, the sheer suppleness that spilled out from her grip, which caused her hooves to adjust again and again to reclaim the fat of her ass. And the warmth. The subtle heat that warmed her legs in a feeling of utter bliss. Shit. “Will you—stop looking at them! It's... rude!”

“Geeze.” Rainbow took a step back while holding up a foreleg in surrender. “Relax, will ya? I didn't mean anything by it.” She kept tilting her head further, the gentle wind of the late evening lifting her prismatic mane slight, the eyes beneath, of course, still set on Twilight's purple behind. “And even if I did, trust me, it's only positive things.”

Twilight sighed, repressed a cry, or the desire to the fly. “Can we walk for a bit?”

“Sure,” Rainbow replied. “So long as you walk in front.”
