New stuff starts at line 1111
>she slowly stirred
>everything hurt
>”Dash! Are you alright?”
>she opened her eyes to a familiar face
>”Twilight? What happened?”
>”Queen Chrysalis got the jump on us. Princess Celestia, Luna, Cadence and I were all taken and you tried to bust us out, alone.”
>that *did* sound like the sort of ballsy move Dash would do
>she tried to stand but her head pounded so she clutched her temple
> and she felt a wet, sticky patch of matted hair
>Dash grimaced at the sting and winced at the blood on her hand
>as well as bruises on her arms, legs…
>”Easy, Rainbow, they beat you pretty hard.”
>Dash got to her feet
>Twilight (frustratingly) dwarfed her, being two feet taller than her own 5’2 height (what with Twilight being a princess and all) but that never stopped *The* Rainbow Dash from kicking ass and taking names!
>she remembered fragments now; Chrysalis attacked the group on route to a royal visit to Manehattan, disguised as the (presumably) already kidnapped Cadence and her few changeling followers replacing the escort
>Dash was already at the city and taking in a flight in preparation for a Wonderbolts event during said visit, just so happened to see a magic battle taking place in the distance and went to help
>the rest of their friends were busy back in Ponyville
>Dash had flashes of Chrysalis wielding some sort of wooden ball that could absorb magic since she somehow managed to beat *all* three princesses at once
>Dash saw Chrysalis sapping Celestia’s power, charged in and got blindsided by a blast of magic, surrounded by changelings and…
>the rest was a blur of fists and feet and pain
>”I bandaged you up as best as I could,” Twilight said and gently held Dash steady, “but I’m no medic. You’ve probably got concussion, and you’re pretty banged up besides, but nothing as serious as your head injury.”
>Dash felt awful, and not just physically
>she’d screwed up her big rescue and now everyone was in serious danger
>”Sorry…”
>Twilight smiled and hugged her closer. “Don’t be. Chrysalis caught an all by surprise, and you did your best.”
>except Dash’s best was a waste, or that’s how she felt right now
>to distract herself, she tried to get her bearings
>Dash and Twilight were in an office, the door was covered in hardened changeling goop
>all the same, Dash felt restless, stood and tried to break it apart
>”I’ve already tried that,” Twilight said. “She’s got the walls laced with that anti magic material. I can cast some magic, but if it goes near the walls, it dissipates.”
>Dash stubbornly continued to struggle until she came over dizzy and her vision whited out
>she slumped against the wall and growled, “stupid goop!”
>”Propolis.”
>”Gesundheit.”
>”No,” Twilight said with a roll of her eyes, “it’s called propolis. Insect resin. The changelings *are* part insect, so it stands to reason they secrete the same substances.”

>as she recovered, Dash asked, ”so what’re we gonna do?”
>”Simple! You’re going to perish!”
>a familiar and reviled figure buzzed in on insectoid wings
>the slender figure of Queen Chrysalis
>or she used to be slender; somehow her body had filled out to a full figured, and taller from her former 7ft by a whole foot
>Twilight immediately fired as strong a magic blast as she could muster at the queen
>Chrysalis cackled and swatted the blast away with something in her hand
>she held a glowing, wood-like sphere, which pulsed and shot a swirling beam at Twilight, who cried out in pain as she was lifted off the ground
>”I’ve already drained all your precious fellow princesses powers. With yours in hand, I’ll be truly unstoppable!”
>”Twilight!” Dash yelled and launched at Chrysalis, who fluttered above the dizzy, haphazard tackle
>then landed and stomped on Dash’s head, and she resumed attacking Twilight with the artefact
>Twilight writhed and hissed in pain
>her horn appeared and rays of pink light were stripped from it and into the sphere
>then Twilight began to shrink
>her princess enhanced curves flattened down, her height dwindled and her wings faded and vanished
>until, with a satisfied sneer from Chrysalis, Twilight fell onto her knees, swayed, and slumped heavily against the wall, her clothes loose and hanging off her much smaller body
>”The power of all the princesses is all mine at last!” Chrysalis screamed in triumph, then stared down at Twilight. “But I’m not done with you yet…”
>”No, leave her alone,” Dash whimpered as she fought against the pain
>Chrysalis stepped off of Dash and picked Twilight off the floor by her neck
>”You cost me my hive. Most of my people! You wounded my pride!! I won’t take any chances with you!”
>Twilight choked and writhed as Chrysalis squeezed her throat with a wild, sharp tooth grin
>Dash gritted her teeth and stood
>”Let her go,” she growled, and staggered toward Chrysalis
>the queen glanced behind her and flipped her slick, straight, deep green hair with a casual flourish
>”Wait your turn, whelp!”
>Dash charged and took a swing anyway
>and received a kick to the ribs for her troubles
>Dash stumbled and wobbled on her legs
>once more she collapsed onto her hands and knees
>”Dash, no…” Twilight choked
>everything spun, but Dash dug deep
>it didn’t matter what happened to her
>Twilight was more important
>she staggered to standing as Chrysalis glared at her, then back at Twilight
>then Chrysalis chuckled
>”It would be more entertaining to hear Twilight’s pathetic pleading as I crush the life out of one of her oh-so-precious friends.”

>Chrysalis tossed Twilight against the wall, then went to grab Dash
>except with a flap of her wings, Dash launched up and kneed Chrysalis in the face
>”I ain’t done yet, bitch!” Dash yelled and dived in with a follow up punch
>Chrysalis growled and took flight, and ascended to get distance, but Dash was unrelenting, striking and kicking, zipping around her and preventing the queen from recovering
>Dash had to press the advantage, she didn’t even need to see well, Dash just had to keep it up and hope something, *anything* would happen that would help
>Chrysalis flew ever higher from the relentless barrage, until she reached a small passage hidden amongst the resin-covered walls
>the queen attempted to flee through the space
>and in that distracted moment, Dash latched onto the arm holding the sphere
>”Let go of me, you pathetic worm!”
>either from the building delirium or out of being insulted, Dash sank her teeth into Chrysalis’ arm as hard and as deep as possible
>Chrysalis snarled in pain
>Dash doubled down by twisting herself and bending Chrysalis’ arm against the joint and tearing out a chunk of flesh out with her teeth
>and the orb fell free!
>Twilight tried to stand but was still dazed
>Chrysalis gasped and went to chase the orb, only for Dash to release her arm and use the queen’s face as a starting block
>she kicked off of Chrysalis’s head and reached for the artefact
>but the exertion finally took hold, and she plunged down in free fall, landed on the orb as it struck the ground, and blacked out

—
>Chrysalis watched as her plan came unfurled by this pathetic midget of a pegasus!
>the Seed flashed and exploded with all the contained power of Celestia, Luna and Twilight, blasting the walls and her carefully formed trap and antimagic-strewn  lair couldn’t contain it
>she couldn’t even enjoy the smug satisfaction of that Rainbow Dash twerp or that insufferable Twilight Sparkle dying in the blast
>the nature of their insipid ‘friendship’ magic meant they were unharmed from the blast
>for Chrysalis though, as the Seed hadn’t had a chance to convert it for her own use, as she had to empower herself with Cadence’s power, so the raw magic scalded her as she not only was struck by the blast, but sent into, and through, a nearby wall
>Chrysalis slammed into the grass outside
>everything was painful
>she saw stars
>all she could hear was a high pitched whine
>the warehouse collapsed, and Chrysalis once more hoped the structure would finish the job
>but a that hope was dashed when she saw her few subjects, unconscious and bound together
>and a much smaller, slimmer, wingless as plain pink-haired Princess Celestia stood over her with a firm, determined glare
>and holding a hammer
>she slammed it down on Chrysalis’ horn
>it cracked and sent a brain-shaking pain through her head
>Chrysalis knew the blow would render her magic null until the crack was healed
>while she was dazed, Chrysalis was flipped over and bound with a length of rope
>”Sister, I have found Twilight!” Luna called out. “Ah, and her friend… but she does not look well, but… oh no.”
>Celestia glanced away from Chrysalis, presumably at her feeble sister
>”What’s wrong?”
>”She is gravely injured!”
>Twilight’s voice then said, “where is that orb? If we can get our magic out of it, I could help treat her, or at least teleport her to a doctor!”
>”Here! I see it but…” Luna said, but sighed, “it’s inert…”
>Chrysalis cackled. “I may not have won, I shall relish in your pain at watching one of the elements perish!”
>Twilight came into view, with a similarly depowered Luna, carrying the bloodied and battered form of Dash. ”B- but… all that magic can’t have just vanished!  Where could…” 
>Twilight frowned and seemed lost in thought for a moment, then shook her head
>”Whatever, Dash is more important right now!”
>Luna handed the Seed to Celestia, who examined it, then scowled down at Chrysalis
>”How does this work? Tell me!”
>”As if I’d tell you,” Chrysalis said and sneered
>”Well uncover its secrets in time, sister,” Luna said and patted Celestia on the shoulder. “Let us tend to our friend first.”
>”Ah, she’s waking up!”

—
>Dash couldn’t see
>it was too bright
>”Rainbow? Try not to move.”
>she stood anyway, she didn’t feel much pain
>”Where is she!?”
>Dash put up her fists
>”I’m gonna kick that bug’s ass!”
>she saw an unfamiliar silhouette… dark colours?
>gotta be Chrysalis!
>”I’ve got you now.”
>Dash took a wild swing
>only for her foe to grab, twist and lock Dash’s arm behind her back 
>”I may not have my magic,” Luna said, “but I keenly remember how to fight. I believe you should relax, Rainbow Dash, lest your delirium cause you to hurt yourself.”
>Dash’s vision cleared, slowly but surely
>Luna was… built like Dash was; wiry and well toned, though lacking her wings and her hair was a plain, two toned dark blue on a 5’7 and modestly curvy body
>Celestia was beside her, still wildly feminine but far more restrained in her curves, and a very *normal* (though still lofty) 6ft and with hair that reminded Dash of Fluttershy
>and, lastly, Twilight, as if they’d first met back in Ponyville, so many years ago, 5’4, cute and a little bit of chubbiness
>quietly sulking and bound with rope, Chrysalis sneered up at Dash, who then stuck a middle finger up at the queen
>Celestia asked, “are you alright? You seem to have made a strangely rapid recovery.”
>Twilight looked Dash over, and frowned
>”She’s right. Your bruises are almost gone. And your  head wound looks more like a graze than the deep cut it was when you were thrown in with me.”
>Dash’s head suddenly throbbed again 
>”I think you spoke too soon… hell, it hurts!”
>it wasn’t the side of her head…
>it was her forehead
>she screamed in pain as she felt supporting hands slowly lower her to the ground
>then, a red hot shiver ran through her body
>”Oh my…” Celestia said
>”I don’t believe it,” Twilight said under her breath
>Dash’s pain faded
>”I’m getting real sick of these headaches.”
>she reached up to rub her forehead
>and gasped as her hand hit something
>something connected to her head 
>a horn
>”Twilight? What’s happened to me?”
>”You’re… an alicorn.”

>Dash paced back and forth, her wings twitching and flexing as she tugged her hair and her new horn at random intervals, while stammering and fretting
>more worrying, her horn kept glowing through a full spectrum of colours in random pulses
>”Rainbow, there’s no reason to panic,” Twilight said as she tried to keep up with her
>”I’m not panicking, *you’re* panicking!”
>Dash winced and suddenly blinked from her current location to a few feet off the ground, and landed in an awkward heap
>”We should coach you in the use of magic,” Celestia said and helped Dash up. “Even if this is a temporary arrangement, I suspect we will need our powers to solve this problem.”
>”And it’s most fortuitous that they now reside in a friend, rather than someone undesirable,” Luna said and glowered at Chrysalis
>the changeling queen smouldered with a low rage as she stared at Dash
>Twilight grabbed Dash by the shoulders. “Rainbow Dash! Focus on me.”
>Dash still looked deep in her confusion, but met Twilight’s gaze
>”The worst thing you can do is remain in a high stress state. We don’t know to what extent your transformation has taken, but thankfully it seems to be relatively mild. Like mine had when Celestia helped me ascend, my powers weren’t too much greater than as a unicorn, so I simply had to focus on flight and the rest came with time.”
>Dash nodded and sighed. “You’re right. Just gotta keep it cool. We’ll deal with this mess in a snap.”
>Dash snapped her fingers and her horn flashed in a rainbow light
>Twilight suddenly shrank until she was a few inches tall
>”What the hell?” Twilight squeaked
>”Sorry! I… I don’t know how I did that!”
>Dash picked up her tiny friend
>Celestia narrowed her eyes and smirked. “You were considering your problems, I assume?”
>”Uh… I guess?”
>”And on her advice, you were considering the issues as lesser. Smaller, perhaps?”
>”I think so?”
>Celestia walked behind Dash and rested her hands on her shoulders
>”I want you to imagine you’re flying. Consider how big this land is, and how small they can be from above.”
>Dash nodded and followed as directed
>”And now consider the remnants of the warehouse, and how large and looming it is from the ground.”
>a large portion of the building remained upright
>it seemed a strange thing to focus on
>a building was a bullding, nothing special
>but… in the grand scheme of things, it was small
>yet it had a presence, she guessed, and it was kinda scary after what almost happened not that long ago
>Celestia whispered, ”now focus on Twilight. How small she seems when you’re flying above her. Imagine descending to meet her.”
>she did
>her horn glowed
>and Twilight re-enlarged back to her former size

>”Magic is often a matter of understanding and perspective,” Celestia continued
>Luna asked, “are you well, Twilight?”
>she checked herself over and said, “looks like it. Good job, Rainbow!”
>”Okay,” Dash said and mopped her brow (and grimaced as she smacked her horn again). “We’ve got this.”
>she suddenly trembled
>”Oh, c’mon! What now!?”
>the depowered princesses all watched as Dash looked down at herself
>she was dressed in a scuffed, torn and slightly bloody training suit, with the zip undone to show her sports bra beneath
>which was where the first changes appeared
>Dash’s watched in wonder as her small, almost flat chest suddenly swelled
>her tiny sports bra was rapidly overwhelmed as it strained and, with a dramatic crack, the strap gave way and launched the supportive garment several feet away
>nestled and bunched into an enticing cleavage, rested two full-handful sized tits, the nips just barely concealed by the track jacket
>before anyone could say a word, Dash shivered again
>the ankle-length track pants quickly pulled higher, revealing her well toned calves as her legs stretched longer
>Dash’s thighs bulged with muscle and filled up the pant-legs to capacity until they were skin tight, and her shoes popped and revealed her feet
>then her ass filed out the seat, until with a panicked squeal and a loud rip, the seam snapped apart, showing off some… shockingly dainty light-blue panties
>Dash watched as her arms, like her legs, thickened with brawn and grew longer
>the cuffs first exposed her wrists, only stopping when they reached her elbow
>she flexed her biceps, her jaw going slack as the thicker masses strained against the fabric
>finally, with a grunt, her whole body pushed higher and bigger in a single, powerful spurt
>her clothes were torn and sundered, clinging to her body and barely covering her shame as, at last, she stopped growing
>Celestia said, in a stunned whisper, “if she wasn’t a princess before-“ 
>”She definitely is now,” Luna finished, staring in amazement at the now 6’7, more appropriately sized and unabashedly sexy Rainbow Dash
—
>Chrysalis growled as more evidence of her failed plan presented itself
>but she grinned; she had a trump card!
>”As much as I’d *hate* to put a dampener on your celebration, you’re forgetting one crucial aspect.”
>all four cretins faced Chrysalis
>”I have Cadance, and you don’t know where she is! She will starve without my subjects caring for her, and I’ll never tell you where she is! Never!!”
>Dash frowned, then seemed in thought
>her horn glowed and, in a flash, the dishevelled and teary eyed Cadance appeared, panicked, then she calmed as she recognised those around her
>Chrysalis’s jaw dropped and she screeched, ”are you joking!?”
>”Cadance!”
>Twilight hugged her
>like the others, with her powers drained, Cadance was diminished from her former 7’3 splendour to a mortal, slender 5’10

>the only difference being this one was reverted to a pegasus
>the other former princesses joined in with the hug, and to add salt to the queen’s wounds, law enforcement finally arrived from Manehattan
>Dash smugly watched between the reunion and down at Chrysalis, who seethed as her subjects were put in chains and loaded into a wagon
>they moved to do the same to Chrysalis, but Celestia approached
>”As much as I’m loath to say it, we may need her, and I want her separated from her people. Have her brought to Canterlot with us.”
>”True,” Luna added, “as confident as I feel that we can get this situation fixed with our knowledge and Rainbow Dash’s powers, perhaps Chrysalis may be swayed to tell us the answers we seek in exchange for a reduced sentence. Besides, she still holds Cadance’s essence within her.”
>the arrangements were made, and Chrysalis sat in quiet contemplation as she was put in magic resistant chains and carted off to Canterlot
>despite everything, there was one faint hope she still held
>Dash was a wildcard, and Chrysalis knew that she still housed a great deal of power within her that had yet to manifest
>the moment to strike may come sooner than later
>she just had to be patient…
—
>Dash still felt a little overwhelmed, but in the presence of friends, she couldn’t deny being a princess was becoming pretty awesome
>she was hungry, and the cart rolled by a deli
>with a thought, and a rainbow coloured flash, a massive sandwich appeared in her hands
>Twilight frowned. “Rainbow! That’s stealing!”
>Dash glanced out the window and, sure enough, a distressed and confused diner was searching for their missing item
>”I didn’t mean to,” Dash said and pouted
>”While it is possible to create something from nothing,“ Celestia said, “much like your rescue of Cadance, most spells that being something to us involve the continuance of an entity.”
>Dash blinked. “What?”
>Twilight explained, “continuance meaning that if it exists, you bringing it to yourself removes it from where it was for it to still exist.”
>Dash blinked again
>Cadance smirked and dug into her experience as a mother. “If you had four apples in your pantry, and took one with you for lunch outside, how many apples would still be in the pantry? Just replace taking the apple yourself with teleporting it to you while you’re still outside. It’s no longer in the pantry.”
>”Ooh.” Dash nodded. “Well, why didn’t say that in the first place?”
>Twilight sighed. “We did, but never mind. We should plan our activities. We’re slowly recovering our weaker magic skills as unicorns, so Cadance besides, all of us can begin experimenting with the artefact. One of us should train Rainbow Dash.”

>Luna raised a hand. “I volunteer. I have the most recent experience with having to relearn my magic after my magnanimous defeat as Nightmare Moon, as well as adjusting to the physical growth I underwent in rapid form as I recovered. Plus I have long since held the practical application of combining manual activity alongside my arcane potential. I feel Rainbow Dash would benefit most from my tutorage.”
>Celestia folded her arms. “Well, I have been teaching children magic since I took the throne. I understand the fundamentals like nobody else, and have the most experience.”
>Twilight put a gentle hand on Dash’s shoulder. “I’m the closest to you. I know you the best, and I’m more than happy to teach you. I’m sorry for snapping about the sandwich, but being a princess is a big responsibility. You helped me learn aspects of that alongside me, so I think I can offer you the best support in return.”
>Cadance shrugged. “I can help too. We share a common bond in both being pegasi who’ve had to learn a whole new skill in magic. And goodness knows teaching my daughter, Flurry Heart, and being a babysitter to Twilight before that, I understand the basic touches to those unfamiliar with spells that don’t require books, even if I can’t cast anything at all any more...”
>Dash looked between the four, and scratched her head

>”Look, no offence or anything,” Dash said, “but nobody knows me like Twilight. Although I’m not sure the whole ‘study the ground while we fly’ thing will work this time, what with… y’know, your lack of wings.”
>Twilight grumbled as she glanced behind shoulders, but nodded. “That and Canterlot’s far busier than Ponyville. Trying to get a straight run of flash-card style learning points about a topic as broad as magic will be all but impossible.”
>”Very well,” Celestia said. “We will focus our efforts on the artefact, and if we learn anything, we’ll let you know.”
—
>Chrysalis was secured in a cell, deep within the confines of Canterlot
>not that she was compliant, but when she was 8ft of regal perfection, she supposed she was flattered that they manhandled her with ten burly soldiers to make sure she didn’t try anything as they shackled her to the wall and locked the door
>with a degree of deviousness that actually even surprised Chrysalis, they had also slotted slivers of magic resistant metal into her horn and put a clamp around it as well
>just the fragments alone would prevent her horn healing, but the anti-magic could well prevent anyone else casting magic on her, so she couldn’t even trick anyone into releasing her
>it was fine, Chrysalis was exactly where she needed to be
>near that braggartish Rainbow Dash would no doubt stay as they sought to understand the Seed of Sorcery
>a non-magical pegasus, filled with the the power of three alicorns?
>*something* had to give
>and it would be catastrophic
—
>”Alright, coach! Lay it on me!”
>Dash shadow-boxed the air as she got used to her new outfit, a casual one from Luna’s selection, and strutted her new body in the corner of the palace gardens
>Twilight adjusted her own simple dress, something she had left behind back before she’d moved to Ponyville, and cleared her throat
>”Learning how to control invoking your horn should be our first step.”
>”Invoking my horn. Right!” Dash swung a mighty roundhouse with her long, powerful legs, then turns to Twilight. “What’s that mean?”
>Twilight hovered a book in front of Dash, which she took
>it was titled, ‘Introductions of Invocations: Junior Edition.’
>”While you’ve proven you can use magic, understanding the difference between wishing to do something with your magic and *actually* doing it is crucial.”
>”Just give me the bullet points,” Dash said and shrugged. “I’m sure I’ll pick it up easily.”
>Twilight put her hands on her hips. “I wish you’d take this seriously.”
>”I am, but this looks about as interesting as watching grass grow.”
>her horn suddenly flashed to life and the plants around her suddenly grew wild and untamed
>”Oops…”

>”See? You’re currently affecting the world with your desires and imagination. Invoking your horn is like… flexing a bicep.” Twilight did so, and couldn’t help but pout at her thin arm after getting used to a nice, firm swell as a princess
>she sighed and continued, “yes, you can curl your arm, but to actually flex requires an extra step. Casting magic *is* that step. Right now, you’re not able to separate the two.”
>”Okay, so how do I stop it?”
>Twilight smirked. “You’re a hands on girl, so we should focus on something engaging, but natural. The more confined and worried you are, the more likely you’ll be to overthink what’s going on and accidentally invoke your magic. How about some good, old fashioned exercise?”
>Dash perked up. ”Ooh, yeah! I don’t even know how strong I am yet!”
>Twilight chirped, ”to the-“
>in a rainbow flash, they were suddenly outside a gym they had passed earlier
>”… gym,” she finished, then gave Dash a look
>”What? C’mon, let’s get a sweat on!”
—
>the door creaked open, and Celestia entered with a couple of guards
>Chrysalis smirked. “Given up already? Are you so reliant on your magic that mustering even a sliver of intellect in learning how to use the Seed is beyond you?”
>the princess folded her arms and glowered at her. ”I could ask the same. I always thought you were clever. Devious, even. Apparently I’ve misjudged you.”
>”Oh?”
>”You’re either insane, idiotic, or desperate. Do you have *any* idea how dangerous the Seed of Supplanted Sorcery is? It can tear the soul out of someone! Even the user. *Especially* the user!”
>Chrysalis stared daggers at her old foe. “Perhaps you should have thought of that before you and your insufferable friends robbed me of my people. Left us barely able to support and defend ourselves.”
>”It was going to happen eventually. Your people require love to feed, and we live in a nation of peace and prosperity, where such things are freely given. As soon as they began to meet the citizens of Equestria, they would have begun to leave. Perhaps if you hadn’t ruled them like a tyrant-“
>Chrysalis pulled against her shackles and screamed, ”they were *my* people to rule for the benefit of the hive! You don’t get to impose *your* rule over my domain, over my *children*, you self-righteous worm!”
>the once steadfast Celestia stepped back from Chrysalis’ size and fury, and even her escort were also taken aback, before stepping in front of their princess to protect her
>Chrysalis sat back down and smouldered. “Get lost. Until you’re willing to barter, i shall give you nothing.”
>Celestia raised an eyebrow. ”Barter? What do you mean?”

>”That dragon pet of Twilight and that traitor, Thorax, deprived me of my people, but as their collective ruler, I lay the blame at your feet. And now you deprive my people of me. Our numbers are few, sources of food fewer, and our predators many. How much changeling blood must flow before you realise you have put my people in an impossible, untenable position?”
>Celestia frowned, then patted one of her escorts on the shoulder. “Let’s go.”
>as the door swung shut, Chrysalis couldn’t help but grin
—
>“More!”
>Twilight panted as she levitated more weights onto the rack and locked it in place
>Dash licked her lips and lifted
>the frame groaned, the bar bent
>but Dash finally found a comfortable level of resistance
>she invoked her magic, using telekinesis to reinforce the bar with a rainbow glow
>but the weight was all on her arms
>ten reps came and went, and Dash took a drink of water as she took a breather
>everyone was staring
>of course they were
>not every day someone as *awesome* as *The* Princess Rainbow Dash graced their gym
>the adoration of the other members made Dash feel…
>tingly
>but the real reward was how right Twilight was about how to learn magic
>with every exercise, from stretching to some cardio to strength training, she added a lesson in magic
>hitting the treadmill?
>Dash learned how to use telekinesis to change the settings, bring the water bottle over for a drink and wipe her brow with a towel
>these were quick applications
>and she learned how to maintain the spell through the legwork, hovering an item while strengthening her calves, thighs and glutes
>now she was mastering deeper application, like shape maintenance
>Dash tucked under the bar again
>twenty reps this time
>”Take it easy, Rainbow, don’t strain yourself.”
>”Relax. I know what I’m doing.”
>”I know, but alicorns have a magical reinforcement to their bodies and we still don’t know how deep that runs through you. If it fails for any reason, since you’re not exactly a naturally made alicorn you-“
>Dash rolled her eyes and said, “it’s fine! Chill out.”
>and her horn sparked to life
>Twilight yelped and shivered as a flurry of snow suddenly swirled around her from an angry cloud over her head 
>”Dang it,” Dash said and, with a casual wave of her hand, dispelled the little cloud. “Sorry, but like I said, I’m not straining. It’s a good level of resistance.”
>Twilight shook off the snow, and replied, “it’s still 2,500lbs!”
>”Heh, impressed?” Dash said as she flexed her powerful arms
>”Ye-“ Twilight cut herself off, blushed a little, then angrily continued, “that’s not the point, and you know it.”
>Dash stood and stretched to begin her wind down, and casually levitated her water bottle to the drinking fountain, refilled it, and brought it to her mouth for a sip
>”One spell mastered and awesomeified! What’s next?”
>Twilight replied, “teleportation is an advanced spell, but you seem to have an aptitude for both yourself and objects.”
>”You mean like this?”
>Dash raised a hand, and her horn flashed
>Twilight yelped as she sent from standing near her friend to… her butt resting in Dash’s palm and perfectly balanced
>except she panicked and toppled, crashing to the floor
>”Ow…”
>”Whoops! Here, lemme help you up.”
>”No, wai-“
>with another flash, Twilight appeared so close she could touch the ceiling
>she screamed as she fell
>only to be caught in Dash’s strong arms, her bigger wings flapping smoothly
>”Gotcha! See? Already got a handle on it!”
>”All the same, let’s go somewhere and make sure you’ve got it all pinned down… and let’s *fly* there.”

>Twilight held onto Dash’s shoulders for dear life
>Dash wasn’t just classically fast
>she wasn’t even faster by virtue of her enhanced strength, or her larger wings
>it turns out alicornism enhancements to an already ultra-fast pegasus made sonic rainbooms the ‘warming up’ speed
>try as she might, Twilight screamed as her grip gave way
>before she could even begin falling, Dash zipped around, grabbed her and hugged her tightly against her chest before crushing another sound barrier
>Dash yelled, ”this is awesome!”
>”Thank goodness! I know you want to test your new limits, Rainbow, but-“
>”I’m barely trying! Check *this* out!”
>Dash dived and spun as she flapped her wings as hard as she could
>her horn glowed and a shining field of telekinesis shrouded them to break up the wind resistance
>they went faster and faster until the world was just streaks of colour
>Twilight closed her eyes
>only moments later, Dash stopped before a mountain
>Twilight opened her eyes just in time to witness a shockwave from Dash’s landing flow up the slope, tearing grass, bushes and even slabs of rock as it dissipated, and causing a small rockslide
>Dash hovered and let the ground settle
>”Dash, where are we?”
>”I think it’s called Mt. Eastplume. Gilda told me about it once.”
>Twilight gawped. “Eastplume? Th- that’s six thousand miles away! We were flying for a couple of minutes, tops!”
>”Yeah, I know, I could do it faster, but I’m still getting used to this new bod!” Dash gave her wings a majestic flutter, then folded them. “Anyway, we learning teleportation or what?”
>she brought them back down to earth, and Twilight caught her breath
>”Okay… I suppose as a person well versed in moving quickly between locations, you know about estimating special awareness based on a predictive flight-path and adapting based on extraneous circumstances.”
>Dash folded her arms. “Uh…”
>Twilight simplified, “imagining yourself in the place you’re flying towards before you get there and making quick adjustments as you see more details.”
>”Oh! Right. Sure.”
>”And we’ve already established this since you’ve been  able to cause teleportation based on what you’ve wanted to do.”
>”Damn straight! Check it!”
>she blinked two feet to the side
>”I’m moving-“
>she blinked beside Twilight
>”-place to place-“
>then in the sky
>”-in zero-“
>she appeared on a ridge thirty feet away
>”-seconds flat!”
>she appeared in front of Twilight again
>”You’re technically moving outside of the realms of physics,” Twilight said. “Faster than the speed of light, even once the spell is in effect.”
>”So you’re saying I’m faster than fast!? Heck yes!”

>Twilight nodded. “I think it’s safe to say you’ve got teleportation down. We should try something more abstract. Currently you’ve been able to teleport to locations in sight and in recent memory. I’m going to give you a location, and you have to teleport us both there.”
>Dash pumped her fist. ”Try me!”
>Twilight hooked an arm around Dash’s waist
>”Crystal Empire throne room!”
>Dash focused, her horn glowed the full colour spectrum
>and, in a flash, they were there
>the guards were spooked and pointed their spears before realising who it was
>most of all a distraught Shining Armor gasped and ran up to them
>Twily! I’ve only just heard you’d rescued Cadance! Is everything okay?”
>Twilight gave him a comforting hug. “We’re still trying to get everything fixed, but Cadance is just fine. She’s helping research how to get all of our powers back.”
>Shining looked over to the current and only princess of Equestria. ”And… wow, Rainbow Dash? You do something to your hair?”
>Dash grinned as she realised she was taller than the big, brawny Shining Armor by a couple of inches
>”What’s shaking, tiny?”
>Dash’s smugness faded
>a hot sensation ran through her, and Shining looked between Dash and back to Twilight
>”Uh… is she okay?”
>Twilight broke the hug and looked
>Dash gasped as her clothes drew tight against her body
>”Not again…”
>they all watched as her head rose higher
>her already impressive bustline swelled out and tore holes in her borrowed top
>Dash watched her bicep as it swelled even larger and shredded the sleeve of her top
>the guards all got an eyeful as her ass burst through her pants, and the her hips finished the job
>her muscular torso strained her top to the fullest, yet her growth only accelerated
>Dash had to cover herself as every scrap of clothing fell away, yet she continued to grow 
>her rainbow hair flowed and fluttered, floating as if she was underwater, the colours blending and swirling into a beautiful, ethereal form
>her magenta eyes flashed white and slivers of pink, blue and red streaked through her irises
>and her horn extended and curved subtly upward, a brilliant and vibrant corona of multicoloured light so strong that everyone had to cover their eyes until, at last, it eased
>and everyone stared in silence as Rainbow Dash had stopped growing
>she was taller than Celestia’s imposing 10ft height…
>looming 12ft tall, in a perfect blend of full figured curves and raw, unparalleled strength, Dash unfurled her wings
>the sky blue feathers had also adopted subtle rainbow hues along the barbs that shimmered in the light
>and while already larger, her wings stretched beyond, reaching wall to wall, with phantasmal secondary wings of pure energy

>Dash smiled and no longer cared she was naked, and instead flexed her arms
>the air was dense with power, so much that Twilight and Shining’s horns fizzled, and she fell to her knees
>”Oh no…”
>”Hell yes!”
—
>“Oh, this is precious.”
>Luna entered the cell and ignored the smug, sharp toothed grin of the prisoner
>Chrysalis stood, looming over the 5’7 unicorn
>”Still no progress, I assume?” Chrysalis snickered and tried to find her arms despite the chains. “It’s almost as if you have no way of knowing how to use the Seed.”
>”You can dispense with your mockery,” Luna said. “I simply wished to ask a few questions.”
>”No attempt to bargain?” Chrysalis huffed and sat back down. “Then I’m not sure we have much to discuss.”
>”You mentioned to my sister of your concerns surrounding your people.”
>Chrysalis rolled her eyes. “Oh, is this the part where you play for sympathy or prey on my perceived fears? Or appeal to my sense of decency concerning the protection of my people?”
>Luna’s brow furrowed. “I was hoping to build a better picture of your desires. You ask for barter and bargain, and yet your intentions are unknown to us beside your constant desires to conquer and feed in the name of the changelings. If you are expecting us to surrender lands or return the people that have sided with Thorax, then we will refuse.”
>”Not much for sharing, are you? I suppose that’s understandable, if pathetic.”
>Luna’s furrowed brow deepened. “What do you mean?”
>Chrysalis put on a forced, doting and condescending tone. “Aww, I’m surprised! I would have thought the *lesser* sister would be all too familiar with the sting of dealing with someone’s unwilling to share their glory for the good of all, or to allow others to flourish rather than bathe evermore in the much adored *sun*.”
>Luna dropped deeper into a full scowl. “You shall not turn me against my sister. It is foolish to believe you can.”
>”A shame. The *old* you would have been a ruler with which I could be willing to form an alliance! A pragmatist. Someone able to act decisively and know they understood better the rigours of leading and that their subjects don’t know what’s best for them.”
>”That’s not true! I am not Nightmare Moon! I was corru-“

>”Corrupted? A cowards excuse! You know as well as I that all that happened to you was your truest desires were unrestrained! Or are you saying you aren’t chafing under the more beloved and experienced leader in Celestia? Or even the ruler of her own domain of the Crystal Empire and mother in Cadance? Or even the magnitude of importance that surrounds Twilight Sparkle? What exactly is your position, precious Luna?”
>Luna couldn’t meet Chrysalis’ gaze, who stood again and got as close as she could to her
>”And without your powers over dreams, who even *are* you?”
>Luna wordlessly left, and Chrysalis smirked as she returned to her bench, and relaxed with a broad smile

>”C’mon, Twilight. A body like this doesn’t need clothing!”
>Dash lounged against the wall of Shining’s bedroom
>Twilight was having a nervous breakdown at the fact that Dash was taller than her while she was sitting
>and had a build that would make Bulk Biceps jealous
>or the fact she kept feeling herself, especially her immense bust
>Twilight grumbled and said, “so what, suddenly you’re too good for modesty?”
>”Yep! I’m a goddess.”
>Twilight thought for a moment, then smirked. “Oh, I guess you’re too good for Rarity too? I guess her whole life’s work in making clothing is a waste of time?”
>Dash gave Twilight a glare for the obvious attack but she looked sheepish at the embedded meaning
>”Hey, I never said that.”
>”No, just implied it by claiming you’re better than everyone else. You’re incredibly powerful, this much is true, but you realise this is supposed to be a temporary arrangement.”
>Dash continued to look ashamed, but finally relented. “Fine, I’ll wear the stupid clothes. Seriously, how do you *not* just wanna flex your stuff with all this power?”
>Twilight did her best to emulate Rarity’s precise magical sewing, but said nothing for the moment
>Dash stood up and levitated several mirrors around her body
>”Damn I look good, though. I never thought I’d carry this much muscle and still look sexy!”
>”A princess’ body adapts to their self-image, crossed with their natural physique before receiving their powers, then slowly growing for years once they do. Luna had always apparently been invested in martial arts while Celestia mostly focused on her caring and nurturing traits as a leader before their ascension. To that end, Luna always retained her toned form while Celestia had fuller curves but they became amplified.”
>”Yeah, but I know I was buff before, but this is *way* more than I thought I’d ever see on a girl and still work. And I’ve never really wanted huge tits, but look at these puppies! And these wings? They’re super cool, but I’ve never seen anything like’em.”
>Dash held up her far less aerodynamic bust, and looked over at Twilight
>her friend was blushing and trying to focus on her sewing as she cleared her throat
>”I don’t mean to sound… well, mean, but you’ve always had an understandable ego, and you’re holding a tremendous amount of power. The two are probably egging each other on and even speeding the process up, and you’re influencing your changes with your personality, hence the wings.”
>”Y’think I’ll grow more?” Dash slapped her own ass and grinned. “I kinda hope so…”
>”Probably. I’m theorising you’re, for lack of a better word, ‘metabolising’ the energy of the princesses. The first growth spurt was probably my lesser amount since I’m still… *was* still developing. This larger spurt was probably either Luna or Celestia’s portion and soon you’ll absorb the other.”

>Dash chuckled. “I can’t wait! I’m gonna a magnitude more awesome than anything or anyone around!”
>”I bet,” Twilight sighed. “Here, your ladyship. I hope my mortal efforts are good enough for you.”
>”Cut it out already,” Dash said as she levitated the toga and sarong over to herself and put them on. “I’m just having fun with this. Just because you’re jealous-“
>Twilight snapped, ”I am *not* jealous! I’m just scared that you’re going to go too far with all this! Goodness knows you’ve let glory go to your head before and it’s clouded your judgement!”
>Dash huffed. “You know what? I don’t have to deal with this.” Her horn glowed
>”Wait, stop! I didn’t-“
>Dash teleported Twilight back to Canterlot
>she then teleported herself outside and looked to the skies as everyone marvelled at the sheer size and power of her body
>it would have been a great time to show off, but she was too annoyed
>she needed a flight
>so she ducked, and leapt
>Dash’s legs cratered the road
>and then she flapped her wings
>a gale force blast levelled the buildings underneath her, but she didn’t even pay it any mind
>she needed to blow off some steam
>Dash flew as hard and fast as she could
>again, to reduce air drag, she formed a cone of telekinesis in front of her
>her physical wings couldn’t get any real purchase thanks to the barrier
>but her magical wings were doing the heavy lifting
>land masses blurred beneath her as she hit speeds she didn’t even know were possible
>and all Dash could think of was how fast she could become when she adsorbed *all* the power inside her
>she couldn’t wait
—
>”You can mask your desperation behind that calm facade all you like, Cadance, but you’re fooling nobody. Just tell me, has your friend has exploded from the amount of power within her or is fast becoming a tyrant? She always seemed to have a good attitude for becoming an irredeemable monster.”
>the princess of the Crystal Empire shrugged as she approached the queen of the changelings
>”I’m not going to play games, Chrysalis,” Cadance said. “Your people will starve and be hunted down by larger beasts without you to protect them.”
>”I’ll breed more,” Chrysalis said. “And with your power within me, they’ll be a stronger brood than before. I’m still waiting for an answer; is Rainbow Dash a monster or a smoking crater?”
 >”You’ll never get the chance to breed more unless you work with us, I-“
>Chrysalis cut her off with a harsh laugh

>”Work with you? So Rainbow Dash isn’t dead yet, otherwise you wouldn’t be flirting with the issue. Just this feeble attempt to suggest I care about any given drone. That’s why you’re weak, Cadance. You have but one strong, virile mate, and the capacity to lure any male to your den to breed. You could be generating and creating an unstoppable bloodline, yet you dote on that pathetic Flurry Heart rather than letting nature take its course. If your offspring are strong, they will surv-“
>Cadance punched Chrysalis square in the eye with enough force to tear the skin
>”Don’t you talk about my daughter, you freak!”
>a trickle of dark blood leaked from the blow, and the queen’s long tongue extended and dragged against the scratch
>”If only you’d show that sort of backbone in using your powers and raising your family, we wouldn’t be here. Weakness breeds weakness.”
>Cadance covered her face in shame as she realised what she had done, and stormed out
—
>Dash had circumnavigated the globe a few times, but grew bored
>so she went in to land in Canterlot
>dramatically, of course
>she landed outside the city by some distance
>but she landed with such speed and force that caused the great outer wall of the city to crack
>closely followed by a sonic boom that finished the job, toppling a large section
>Dash winced. “Oh, crud.”
>as guards mounted a rescue mission, Dash called out, “I got it! Leave it to Princess Dash!”
>she lifted the wall pieces with her magic
>except she hadn’t waited for some of the rescuers to climb off
>they screamed as they tried to hold on to the loose rocks
>but a few fell, only for Dash to widen the telekinetic field and snare them
>”Gotcha!”
>but her divided focus meant some of the wall fragments fell on the nearest buildings or crashed down near the people on the ground
>”Damn it! Hold on!”
>Dash flew in and took hold of the largest piece of wall, so she could use her magic to hold the outer areas with smaller chunks and the majority of the people
>but it wasn’t designed to be held up by a single point, as cracked in two
>Dash juggled the various pieces, but in desperation just teleported everyone away from the area and to somewhere familiar; Ponyville 
>the focus it took led to the broken wall to smash on the ground and cause even more destruction
>”Damn it!”
>Dash let herself drop
>only her impact caused yet more carnage
>so Dash growled and stomped up to Canterlot castle on foot, with everyone giving her a fearful and wide berth
—
>elsewhere, Chrysalis felt the vibrations of what had to be ensuing destruction
>and laughed

—
>Dash was used to being the centre of attention
>but not like this
>people should be admiring her
>she should be their hero
>hell, she was a princess, right?
>they should be worshipping her!
>but the fear she could see
>the fear she could *hear*
>”Leave us alone!”
>”Don’t hurt us!”
>Dash frowned and looked at the cowering people
>”Relax, I ain’t gonna hurt anyone. I’m just heading for the palace.”
>the crowd gasped and talked amongst themselves
>only for a voice to pierce the rabble
>”Leave our princess alone!”
>Dash saw a young girl
>a full on tomboy at that; short hair, scuffed knees, a devil-may-care gleam in her eye
>she stood, arms spread wide, between Dash and the quickest route to the palace
>she reminded Dash of Scootaloo…
>a couple more people joined her, standing in Dash’s way
>it was pointless, Dash could step over them, flown to the palace, pick another road
>but her powerful shoulders slumped
>Princess Dash was the bad guy…
>they were trying to protect the *real* princesses
>this wasn’t her
>the hell was she doing?
>*The* Rainbow Dash was meant to be a hero
>sure, sometimes she went too far
>and she was known for her brutal honesty and ability to put her foot in her mouth
>but she did the right thing
>she fought damn hard for her place as a Wonderbolt
>that was *all* Dash, fought with effort, and honed skill
>and a lot of help from her friends
>not some stupid powers
>Dash closed her eyes and teleported to the palace gates
>and saw her
>Twilight, preparing to head out into the city with a small band of guards talking about an ‘attack on the city outskirts’
>Twilight didn’t have her full magic, yet there she was, ready to throw down
>then Dash and Twilight’s eyes met, and the less than certain Princess Dash braced herself
>for all the power she wielded, for as big as she has grown
>Twilight’s judgemental gaze still frightened her
>as Dash entered the courtyard, Twilight took a deep breath, but Dash cut her off
>”I get it, I screwed up, I know! I don’t know my own strength, I’m a literal giant asshole, and I’m sorry.”
>Twilight’s stern gaze softened and she approached and put a hand against Dash’s leg
>”I’m sorry too… I *am* jealous of you, learning spells that took me years to master as easily as you have. I know you have a lot of power, but that’s some serious aptitude you’ve shown all the same. That’s all you, not any raw alicorn might that our magic has given you.”
>Dash and Twilight smiled at one another, then Dash crouched down and hugged her friend
>”You’re still my egghead, Twi.”
>”And you’re still my brash, hard-headed but loyal and very dear friend, Rainbow.”

>they spent a long moment, before Twilight stepped back
>”I haven’t had a chance to ask about how the research has been going before I heard about your… dramatic entrance.”
>Dash stood and cocked an eyebrow. “Really? I know we were away for a while, but I figured the others would have *something* by now.“
>”There you are! Finally!”
>Cadance stormed out, holding the Seed of Supplanted Sorcery
>she looked absolutely *pissed*
>”About damn time! Here, take this stupid thing before I jam it up that bug bitches ass!”
>Dash and Twilight have each other a glance before Cadance practically punched Twilight in the gut with the Seed
>Dash stepped up (and over) Cadance and growled down at her
>”Hey! What the hell’s your problem!?”
>Cadance snarled up at Dash for a moment, then suddenly clutched her head and stumbled
>Twilight caught her. “This isn’t like you at all.”
>”I- I don’t feel myself… Celestia and Luna have been acting strange too.”
>”I haven’t had a chance to talk to them yet,” Twilight said. “What’s been happening?” 
>Cadance winced, then growled again. “You’re meant to be smart, so figure it out your damn self!”
>she caught herself , and said, “we’ve haven’t been able to get much work done. We tried to figure out how to use the Seed, but nothing we tried worked. Each of us went to try and talk to Queen Chrysalis and reacted poorly to her words. Luna’s become depressed and doubtful of herself, Celestia’s become uncaring and apathetic and I… I…”
>Cadance once again grew infuriated and roared, “I’m gonna burn that insect bitch at the stake!”
>Dash said, ”okay, Cadance, sorry but you need a timeout.”
>”Don’t tell me what to do, you giant bimbo!”
>Dash rolled her eyes as her horn glowed and-
>Twilight panicked. “Wait, don’t hurt her- oh…”
>she watched as Dash teleported a comfy, plush cloud bed nearby, then put Cadance on top of it, and finally put her into a deep sleep before sending her drifting up into the sky

>”Don’t worry, she’s a pegasus, so she’ll be fine,” Dash said with a smirk. “Cadence obviously wasn’t having a good time so I‘ve given her an afternoon nimbus-nap. That helps *me* when I’m feeling cranky.”
>Twilight beamed a smile. ”Assertive, decisive, but caring and gentle! As a princess should be.”
>”I’ve learned from the best,” Dash said as she winked at Twilight
>”Now we’ve got to figure out what’s going on… I trust Celestia wouldn’t have just given up on researching the Seed without exhausting every avenue. I theorise that means the artefact is closely tied to Chrysalis in some way.”
>”What’s the play, coach? You need it, Princess Dash’ll do it!”
>Twilight stood proud and said, “we have an imperative need to-”
>”go on a grand adventure of daring-do like Daring Do?” Dash hopped from foot to foot. “A giant ‘fix the problem’ spell involving catastrophic levels of magic?” She took wing and twirled as she pumped her fists “An epic laser battle in the skies backed with even more epic rocking tunes under the light of the full moon!?”
>”Even better than all that! We need…” Twilight clapped her hands excitedly ”…to go to the library!”
>Dash slammed ass-first into the ground with a huff (and a cracking of the courtyard)
>”Pfft. Boring nerd stuff.”
>”Being a princess sometimes involves-“
>”Yeah, yeah,” Dash folded her arms and grumbled, “sitting down and analysing the problem.”
>the pair entered the palace together
>though Dash couldn’t help but give Twilight a light hip-check, sending her tumbling to the floor
>”Hey!”
>Twilight telekinetically pulled a large crease in the palace entrance’s carpet in front of Dash as she smirked over her shoulder
>and she tripped, landing so hard it shook the ground and knocked a few paintings off the wall
>they looked at each other and smirked, then continued on, side by side as they shared a laugh
—
>Chrysalis kept peering out of the window
>plenty of expected carnage, but it suddenly stopped
>she frowned and paced as much as she could
>”My Queen,”
>a voice outside the bars
>one of the guards shifted briefly into his changeling form as he entered
>”It was just as you predicted. The Rainbow one caused enough of a panic that a few of us managed to infiltrate-“
>”I know my own plan, fool! Hurry up!”
>the ‘guard’ undid the horn clasp and used some tweezers to remove the slivers of metal from her horn, then loosely replaced the clamp
>Chrysalis ordered, ”now go and await the counterattack.”
>she was left alone once more, and sighed with relief as her horn began to rapidly heal
>only for another visitor to arrive
>”We need to talk,” Twilight said

—
>Dash sighed as she watched Luna and Celestia
>the princess of the night sat on her throne, performing her very best ‘slightly-criticised Rarity’ impression; sobbing, wailing and cramming ice cream down her mouth between breaths, surrounded by about twelve empty tubs
>Celestia kept rolling her eyes at her sisters inflated and noisy despair. “Could you shut up? Or whatever. I don’t care.”
>”I am truly pointless! It is all as fruitless as a fruit-free fruit salad!”
>”That wouldn’t even be anything,” Celestia snipped
>Luna bawled harder. “Wahhh, I cannot even metaphor right! Woe is me-he-he…” Luna tossed another tub away and levitated another one in from… somewhere
>Dash ran a hand down her face as she looked over the Seed before slipping it between her immense cleavage
>she then mumbled, “c’mon, Twilight, hurry up.”
>”Ugh, what’s the hurry?” Celestia muttered. “It’s not going to matter anyway.”
>”Y’know what?” Dash said and stormed up to the sisters, “I don’t care what kind of magical bull you’re suffering. While I’m princess, I’m gonna motivate the crap outta you!”
>”Sure, whatever you say,” Celestia said. “Not like I care.”
>”Oh, you’ll care alright!” Dash said and picked Celestia out of her throne. “Twilight’s one of my best friends, and I know more than anyone how much you inspired her to give everything she’s got in everything she does. Well now it’s your turn! And those ‘average at best’ boobs aren’t gonna be an excuse.”
>Celestia sighed, “do I have to?”
>”Yes! And as for you!”
>Dash kept Celestia aloft with her magic and then picked up Luna
>”Nothing fights off a downer like adrenaline and post-exercise endorphins! We’re gonna go warm up with a stiff jog, then we’re gonna lift! I’m gonna motivate the heck out of your tiny ass!”
>”But I am worthless! Nothingness possesses more value than I!”
>”And after I’ve worked that tiny ass through some hardcore exercise, you’ll make worth seem worthless! I will chisel you into a lean, mean butt-kicking machine!”
>Dash double teleported Celestia and Luna’s loose clothes out and replaced them with some form fitting exercise gear
>”One sprint around the palace grounds, through town and to the gym! Now march!”
>”But I don’t want to-“
>Dash evoked the royal Canterlot voice and bellowed, “I said MARCH!”
>the two de-princessed princesses ran in a panic, followed by the stomps of the *very* Princess Dash

 —
>”I was beginning to wonder when you would show yourself, my little nemesis,” Chysalis said. “Have you come to appeal to my better nature? Or perhaps regale me with a lesson in friendship? Oh. Or maybe you’re here to turn me loose in a shocking display of mercy?”
>Twilight shrugged. ”Nope. Just here to ask you what your plan is.”
>”To safeguard the changelings.”
>Twilight huffed. ”Provably false.”
>Chrysalis cocked an eyebrow, and then noticed the guard behind her old for give her a quick transformative flash of his hand, 
>”You’re going to let them die off while you play these games,” Twilight continued. “Sure, I have no doubt you can breed more, and I’m sure they will benefit with your enhanced powers, but exactly what do you think you’ll do here, trapped in a dungeon, and under watch? It doesn’t matter what you do to the princesses, the guards alone will repel you.”
>Twilight got closer
>”In fact, how do you intend to fight Rainbow Dash? She’s practically a force of nature at this point. Capable of tremendous destruction with a casual thought. Do you really believe you can win this? Even if you escape, do you think defeating us will somehow stop Dash from potentially obliterating the changelings out of grief and anger?”
>Chrysalis stared daggers at the bookish girl. ”For all your vaunted knowledge, Twilight Sparkle, you know nothing.”
>Twilight winced and held her head, then blinked as her expression turned vague and vapid. “Huh? What are we even talking about?”
>Chrysalis chuckled, though studied Twilight as she gazed around in a dreamlike state.
>“That was faster than normal… oh well.”
>Chrysalis removed the clamp from her horn, and with a green glow, her shackles vanished
>Twilight whined, “hey, like, shouldn’t you not be doing that or something?”
>”Oh, it’ll be alright,” Chrysalis said with a sneer, “revel in your ignorance. I look forward to nourishing myself on your wits. And then, when I drain your moronic friend Rainbow Dash dry of her power, I shall peel your skin and wear you as my robe as I take over all of Equestria!”
>Chrysalis patted Twilight on the head, each one becoming harsher and harder
>”Now, save me some time; where is the Seed, my dim-witted pet?”
>Twilight hopped from foot to foot and looked excited. ”Like, oh, I know! It’s up some stairs!”
>”… yes, and?”
>”It’s in a *big* room! With lots of windows!”
>Chrysalis growled, and slapped Twilight to the floor
>”Damn it! Definitely a faster change than normal. I’ll get it myself!”
>Chrysalis left the chamber with her guard, but not before locking the gate behind her, and transforming into a duplicate of Twilight

—
>”Work it! Feel the burn!”
>Celestia and Luna were bathed in sweat
>Celestia’s apathy was at odds with the fear of a twelve foot titaness driving her like a dog
>and while Luna fared better, being fitter than her sister, but having suffered a sugar crash from her ice cream binge, she was struggling just as hard
>but Dash wasn’t relenting
>nor was she holding back herself
>it may have been her second workout that day, but she had *all* the stamina
>after five sets of ten reps of every heaviest dumbbell she could fit on a whole rack, then used poles to place two of those racks together
>and she split her magic, half on reinforcing the frame and the other half of her power adding even more weight
>she didn’t know how much weight it was, but even she was starting to struggle by the end
>and slowly placing the weights down, the floor cracked, and the neighbouring buildings complained about a continuous moderate tremor during her exercise
>Dash was easily stronger than even the biggest dragons at this point
>but she was beginning to feel *it*
>the power inside her was building and ready to finish her absorption of three princesses essence
>but she wasn’t sure if she wanted it any more
>she was happy like this
>Dash had power, but she had limits
>and limits were the fun part, it gave her something to strive against
>being awesome was because of achieving the impossible, not just by being so powerful it was trivial
>which suited Dash just fine…
>she checked the clock
>Twilight should have done what she needed to by now
>Dash stood and cleaned herself with her magic, and turned to the struggling princesses
>”Keep it up, weaklings! If I come back and you’re slacking, I’ll make you do it all over again! Do you hear me?”
>they both gave a muffled agreement
>Dash bellowed in the Canterlot voice, ”I can’t hear you!”
>”Yes, Princess Rainbow Dash!”
>”That’s more like it!”
>she left the gym, and looked at the sky for a moment, then looked over her shoulder
>”You’ll thank me later, guys,” Dash whispered. “We just needed to get you out of the palace for this… sheesh, I hope you’re right about all this, Twilight.”
>she took flight, and headed for the palace

—
>”The Seed *has* to be here somewhere. Look harder!”
>her drones returned to and left Chrysalis alone
>she had finished binding the last of the palace guards with her resin, then shifted forms into the alicorn Celestia
>the palace was under control; most had been fooled info helping with the broken wall
>only a skeleton crew was left, who were now strung up and subdued with her magic
>now came the true test
>while she had lost the Seed for now, she still had plan-B
>part of her evolution from consuming Cadance’s power, and the reason for her ambivalence to the deaths of her people…
>Chrysalis wouldn’t need to breed to grow her numbers
>with an isolated guard, she broke the spell keeping him unconscious
>as the guard began to stir, she tapped into the stolen trait of natural empathy of the ruler of Equestria
>she caressed the guard and purred, in Celestia’s voice, “my loyal subject, rest easy. I’ve will protect you. I love you, so dearly… I want you…”
>”P- Princess Celestia,” the guard whispered
>Chrysalis stroked and then kissed his cheek, then hugged him close
>she could feel his rapid heartbeat
>and with a flash of green in her eyes, she began to siphon his energy
>he gasped, then sighed, as if resting easy, knowing that his beloved ruler was safe
>after all, the connection was so much more heartfelt when Chrysalis wasn’t having to maintain mind control to fool the prey
>she was layering Celestia’s stolen empathy over natural disdain
>the power was so much deeper and richer!
>she was fulfilling his deep seated wishes for such closeness with Celestia with ‘pure’, organic, heartfelt emotion
>so intense was the drain, that colour left his body and his brawn melted away, leaving him emaciated 
>then Chrysalis sank her teeth into his neck, blackness filling his veins as she injected a venom that would eventually transform him into a compliant, uncaring drone
>one unable to disobey her, and thus prevent him being converted to one of Thorax’s vile thralls!
>and as Chrysalis stepped away as she digested his energy
>and she giggled, then laughed, then cackled as her body subtly swelled an inch taller, a little stronger and bustier
>so much power from just one simple peon!
>Chrysalis moved on to the next bound prisoner
>a female, one of Luna’s elite night watchers, alone in a corridor
>the queen shifted into Luna’s tauter, athletic form
>and she broke the guard from her reverie
>”M- my lady!”

>curiously, she looked around and noticed they were alone, her mannerisms shifted
>”Lulu… what’s happening?”
>Chrysalis once more dug into her stolen personality traits
>and it came with fleeting moments of memory
>Chrysalis knelt beside the guard and said, “all is well, my beautiful Dancing Shade. You are safe.”
>she ran her fingers through Dancing’s silky, deep red hair, then stroked her jaw and brought their lips together
>once more, as Dancing closed hers, Chrysalis’ eyes flashed green
>this was even more intense than the last!
>Dancing gave into the moment, as her curves melted and firm physique weakened
>and, with a parting, venomous nip of the neck, Chrysalis primed this one for transformation too
>she consumed the energy
>and immediately cried out in bliss as she stumbled and leaned on the wall
>arousal shook through her, as the stolen memories mingled with the raw, untamed essence of Dancing’s secret, reciprocated love for the moon princess
>her form was forcefully shifted back into the changeling queen 
>and she moaned as she sprouted a whole foot taller, to 9ft, her resin clothing straining
>her slender limbs gaining smooth, subtle strength and her curves ballooned outward
>she panted and recovered
>that intense feeling!
>there was something to this genuine emot-
>”No!” Chrysalis snarled
>she was aware of the risks, and this was why this emotion drain was plan-B, rather than just stealing the power of the princesses
>but if this was what he power she could gain from Luna’s secret lover, and she had recently stole some of Twilight’s soul…
>those other girls; the brutish farmer, the meek, animal obsessed worm…
>they were the elements of harmony
>the untapped power Chrysalis could attain from them!
>she just needed to finish absorbing the stolen trait she had taken from Twilight, leaving her dull and idiotic
>Chrysalis suddenly saw a figure flying in from the city
>Rainbow Dash
>Chrysalis bared her teeth, then shifted into Twilight’s form
>she just had to play for time

—
>”Hey, short stuff,” Dash said as she landed and approached the palace door’s guards, “is Twilight around?”
>”She’ll be with you soon. Please wait in the throne room.”
>Dash stared at the guard, then smiled, saluted and said, “sure thing.”
>Dash headed as directed, to the empty throne room
>it was… eerily quiet
>but Dash smirked as she used the opportunity to sit on Celestia’s throne
>”Sheesh, she calls this comfortable? This ain’t no chair befitting an amazing ass as mine.”
>she stood and teleported Celestia’s throne elsewhere
>then called in a massage chair she’d seen in a fancy Canterlot boutique
>she then wielded even more power to make it enlarge in size, and sat down
>it promptly entered reclining mode and buzzed as the little heaters and motors massaged her back, butt and legs
>”*This* is being a princess!”
>with another wave of her hand and glow of her horn, the tapestries and flags were replaced with Wonderbolt posters, emblems and even a few of her own promotional fliers, depicting her in a stylised way
>well, her *old* self, anyway
>they’d need updating to capture her true awesomeness
>she rested her worries away before, at last, Twilight entered
>”Hey, Rainbow Dash. Sorry I took so long.”
>”S’up, Twi! Whaddya think?”
>Dash gestured to the redecorations
>”They’re… certainly ostentatious.”
 >Dash stared at Twilight for a moment, then shrugged
>”So, what’s happening?”
>”I think I have an idea on how to fix things, but we’ll need the Seed.”
>”Oh, that thing? I thought you had it.”
>Twilight pouted. “Strange. I wonder where that went. Never mind.”
>Twilight smoothly strolled up to Dash
>”You know… this really is a good look for you.”
>”Oh, absolutely,” Dash said and flexed. “I don’t mean to brag, but… okay, I kinda do, but I’ve never looked better!”
>”I wholeheartedly agree, in fact…”
>Twilight moved closer still
>climbed on the reclining chair
>and rested her hands on Dash’s thick, powerful thigh
>”I’ve been meaning to say that you were special before, but now?”
>Dash lay still as Twilight slowly ran her hands up and ran them over her abs
>”You’re the most special girl in -all of Equestria. A woman I could worship all day.”
>Dash smirked. “Go on.”
>Twilight crawled up and leaned over Dash’s face
>”No more words…”
>and leaned in to kiss… with a light flash of green in her eyes

>Dash pinched Twilight’s lips
>”There’s just one problem,” Dash said
>Twilight frowned
>”I ain’t into chicks who change their hair colour. Or skin colour.”
>she launched ’Twilight’ hard against the wall
>but Chrysalis transformed mid-air and controlled her flight, landing smoothly and baring her sharp teeth
>”No matter,” she said, “I’ve already won.”
>Dash cocked an eyebrow as she realised Chrysalis was about as tall as she was, though nowhere near as brawny
>”Awful lotta confidence for a skinny-assed, overgrown bug.”
>Chrysalis sneered, “oh, I have no doubt you’re stronger than me, but you’re undisciplined and lack full control. When your full power comes into fruition, you’ll either perish from the inability to control so much magic, or become so dangerous, everything around you will come to harm! You’ll *beg* me to drain your power! I- AAAGH!”
>Chrysalis was cut off as her arm suddenly bent backwards with a crunch
>a quick glance showed a rainbow coloured beam had struck it, and blasted a small crater behind Chrysalis
>”You ever pulls the legs off a spider as a kid?”
>Chrysalis snarled and used her own magic to pull it back in place and heal the injury
>Dash chuckled, “just me? And anyone ever tell you that you talk to much?” 
>she charged at Chrysalis, narrowly missing with a punch as the queen teleported to the side, then unleashed a blast of magic in return
>Dash yelped as she was struck
>she had spent so long being big and all-powerful, she’d forgotten how this mess started
>the pain gave her clarity
>pain from this bitch in particular
>Dash blinked behind Chrysalis and spin-kicked her sprawling through the throne room wall
>”Payback time!”
>Chrysalis pulled herself free from the rubble and growled
>her eyes widened as she saw it
>stuffed in Dash’s cleavage
>The Seed…
>Dash followed her gaze, only for Chrysalis to teleport in while she was distracted
>and plunge her arm between Dash’s tits
>Dash grabbed Chrysalis’ arm
>and they began struggling over the artefact
>Chrysalis’ experience with magic made up for her physical shortcomings as she warded off Dash’s domineering strength
>Chrysalis struck Dash with bolt after bolt of magic, or tried to teleport away, only for her foe to punch, kick and knee while cancelling the worst of the queen’s magic with her own 
>the magnitude of power clashing caused the ground to shake, and the walls to crack and crumble
>with a growl, Dash teleported them both out into a large field
>and just as the fight resumed
>Dash felt it
>her ascension was coming
>it made her shiver and clench
>so much power!
>but Chrysalis took the momentary distraction to steal the Seed

>”You lose,” Chrysalis hissed and pointed the Seed at Dash
>”Yep. Got me dead to rights,” Dash replied and masked a smirk as she continued to clutch at her body
>undeterred, Chrysalis fired a beam of energy at her
>it met its mark, and began to drain Dash’s power, just as more flooded her body
>Dash chuckled as her body subtly grew and shrank unevenly
>a few cup sizes up here, a little less muscle there, then more brawn, less bust
>”You’re so desperate it isn’t even funny,” Dash said and approached, fighting the transformation to and from greatness
>Chrysalis snarled and stepped backward, but her determination was steadfast
>once Dash started to shrink in full, Chrysalis would strike
>but still Dash’s ascension was trying to continue
>then Chrysalis felt a hollowness within her, being drawn into the Seed
>”No! I should have enough to withstand it!”
>”Enough soul? Nah, you ain’t got squat.”
>Chrysalis’ stubbornness refused to let her accept this. ”What kind of scheme do you think you’re pulling? You’re the idiot of Twilight’s saccharine little group! Even that moronic pink one is wilier!”
>Dash grabbed the seed and kicked Chrysalis in the chest, sending her sprawling
>Chrysalis writhed as she felt a part of her get peeled from within, and she felt lesser, as if missing something
>”Just as planned!” dash said with a big, mocking grin. “I didn’t like doing it, but Twilight’s always been the one to make the sacrifice play.” Dash examined the Seed and and sighed. “Seems when this thing takes a soul, it takes part of their personality. You took Cadance’s loving side and left her angry, Luna’s pride and duty and left her in despair, and took Celestia’s empathy, leaving her uncaring. But you didn’t get Twilight.”
>Dash stomped on Chrysalis’ chest, but her will to fight was crushed, so the new princess continued
>”Seems in order to use the Seed, you’ve gotta sacrifice others and keep draining souls to get the power. I Imagine someone gives as little a damn as you do about your people had plenty of ammo to get things rolling to steal Cadance’s power, huh? Twilight gave her nerdiness to me. Never thought I’d act like an egghead, but here we are. As for you?”
>Dash pressed down harder and harder until Chrysalis couldn’t breathe
>”Seems I also got a little of your ruthlessness. ‘Cause all I wanna do right now is crush you like the bug you are and be done with you.”
>Dash instead pointed the Seed at Chrysalis, and it fired a beam of light
>Chrysalis snarled and  fruitlessly struggled, but as her consciousness faded, her size did too
>she shrank back to her former, though still lofty, 6’5 and slim frame
>then, without the rivalled power of an alicorn to stop her, Dash sent her back to her hive… with a tiny hint of something extra to hopefully change things up, courtesy of Twilight’s smarts and planning

>with a series of effortless teleports, Dash returned the princesses to their homes, except Twilight, who she sending to Ponyville and in front of a deeply confused Applejack
>AJ would look after ditzy Twilight just fine for a little while
>Dash headed to a vast field to celebrate
>she had won
>and she *could* restore her friends’ powers and personalities, and restore anyone Chrysalis had drained too
>and she would
>definitely
>eventually
>but… there was a once in a lifetime opportunity in her hands
>to be the most undisputed, unequivocally (damn, that eggheaded aspect was doing work) most awesome person in existence
>so she turned the Seed on herself, and absorbed all four alicorns magic, and even the extra essences Chrysalis had stolen
>finally, the fragments of spirits too
>she didn’t even need the Seed any more, so she crushed it into splinters
>she had all the power she needed for when she was ready to relinquish goddesshood
>and cried out as she began to glow
>”Oh, yeah, that’s… different!”
>she felt the aspects of the princesses inside her too; the kindness, strength and empathy to endure all the raw power
>and they helped her body contain more magic than any single soul had ever felt
>Dash began to grow
>her hair burst into pure light that whipped and crackled like lightning, her eyes burned like roaring magenta flame
>her ethereal wings spread so far she couldn’t see where they ended
>their presence engulfed the world like an aurora borealis flow
>but in the here and now, Dash felt a surge run through her
>in moments, Dash’s clothes burst
>and she once more didn’t care who saw her
>she had already become a perfect version of her self, so her huge bust and firm, powerful muscles didn’t change in form
>but the ground pulled away in short spurts
>trees went from as tall as she was, to waist high
>Dash wasn’t satisfied though
>this was lame
>she needed an audience for this awesomeness
>so she she blinked near the still broken wall of Canterlot
>”Take five, everyone!”
>she waved her hand, and the wall was simply fixed in a glow of rainbow light

>”Sorry about earlier. A little too much pride, and too little understanding. Now I’m the princess you guys deserve. For real, this time. Now check this out.”
>Dash felt more assured as she approached Canterlot
>all those eyes on her…
>the princess aspect within her loved it
>Dash moaned as she had a growth spurt
>the lofty walls of Canterlot dwindled before her
>the ground cracked underfoot, but then Dash smirked as the damage melted away
>*she* was in control now
>*The* Princess Rainbow Dash was a goddess
>what she *wanted* to destroy would be destroyed
>and what we didn’t, wouldn’t
>Dash wanted to test this theory
>so as she hit a hundred feet tall, she stepped on the wall and pressed down
>despite the fact Dash knew it had no chance of withstanding her weight, it did
>this was her reality
>and knowing the tiny people would be safe, Dash gave in fully to her hype, ego and untapped power
>she exploded in all directions in raw size
>her foot fully blanketed Canterlot, and she stepped back as the world dwindled downward
>yet more power flowed through her limbs, stretching them longer and longer, thicker and thicker
>she wasn’t even sure if she could stop growing at this point
>with one step, she stood over Ponyville
>”Hey, peeps! Just your friendly goddess here to say not to panic, you’re in safe hands!”
>she saluted, then her eyes lidded as an erotic shiver ran through her
>just the thought of her magnificence… she wished she could see it from a little person’s view
>so she did; she briefly saw through Twilight’s eyes, using their bond
>and, yep, looking up, Dash’s thousands of foot high form looked as amazing as it felt
>so she and decided to tap into ever more of her budding power, forcing more and more to pour into her body
>Ponyville diminished until she could have smothered it with a fingertip
>so she waved farewell, and took flight
>to her subjects, it was a gentle, warm breeze flowing across the world
>for Dash, the single stroke of her gigantic wings launched her from the planet, and as more and more people witnessed her majesty, she finally succumbed to an itch that had been building for some time
>she was outrageously horny, and her growth wasn’t ending either

>so as she swelled and watched the world shrink until it was around as big as she was
>and, unabashed, she grinded against it
>they’d be fine; maybe a little confused as a planet sized girl like her used their home as a sex toy, but whatever
>today, Dash was *everyone’s* idol to worship and enjoy, up close and personal
>her nation-sized slit felt every city, tree and mountain
>but, as before, her magic kept them intact
>she grew again, until the planet could be her little spoon
>the curvature of the world and the highest peaks grew slick with Dash’s love juices
>her moans defied physics as her cries filled the skies of her home
>until, with a scream, Dash came
>storms roiled and rumbled
>gale force winds tore through valleys
>yet everyone was safe as she rode her climax
>Dash was numb for a time, riding the afterglow
>”That was fun,” she said with a sigh, “but it’s kinda lonely out here.”
>Dash lifted the planet before her and realised she had grown again
>the planet fit in her palm
>and she felt balanced; this was all the power anyone could ever dream of
>Dash controlled everything
>”See, from now on, if anyone doubts Rainbow Dash’s awesomeness, I’m gonna tell’em just how small everyone really is to me...”
>Dash then frowned
>all this power…
>it just wasn’t fun
>like she realised before, it’s the limits that make things fun, to challenge herself, to defy expectations and predictions
>with a wave of her hand, the planet morphed and changed; the sky turned rainbow coloured, everyone had wings
>then with another wave, she restored it to normal
>okay, Dash had to admit, all this power *was* fun
>and she could probably do a fine job protecting everyone
>this wasn’t *her* though
>she missed competing with AJ, or pranking with Pinkie, or her kinship with Fluttershy, or even Rarity’s dramatics
>she missed Twilight most of all
>”Meh,” she said with a shrug. “I’ve had my fun.”
>she closed her eyes and pinpointed Celestia, Luna, Cadance and Twilight with her thoughts
>and she released their powers back to them, as she shrank back down onto Equestria
>so much power left her
>it was intense, even painful!
>it was too much!
>she shrank, and it overwhelmed her
>then she blacked out

>she slowly stirred
>everything hurt
>and she felt… small
>what just happened?
>”Rainbow? Ah, you’re awake!”
>Dash groaned as gentle arms pulled her into a hug
>it felt really nice
>comforting
>especially the big, soft tits
>princess big
>wow, where’d that come from?
>she opened her eyes and was greeted by the big, pretty purple and glistening wet eyes of Twilight
>Dash said, “Hey Twilight. Good to see you’re back to being large and in charge. I’m guessing Cadance, Celestia and Luna are all okay too?”
>”Yep! All thanks to you! You saved the day.”
>That definitely was the ballsy sort of thing Dash would do
>but… something about this whole thing made her feel dissatisfied with getting all the praise
>”It was your smarts that saved the day, Twi.”
>”Which were in you. Never forget that. The heart rules the head, and you’ve got a big heart indeed.”
>Twilight let Dash rest back on the bed 
>they were in one of the guest rooms in Canterlot castle
>Twilight awkwardly glanced to the side and said, “to be honest, even when I wasn’t in control of all my faculties, I was worried you wouldn’t let go of all that power.”
>Dash shrugged, “as cool as ruling all of… well, *everything* would be, pushing myself to improve wouldn’t be any fun if there were no improvements to make. It’s the limits that make my awesomeness stand out, not some princess powers or bring a goddess. I’ll stick to just being me!”
>”Hmm… about that.”
>Twilight reached forward and tapped Dash’s forehead
>or almost, her hand seemed a little too far away
>yet there was a light shock that ran through Dash’s mind
>and a small pulse of rainbow light
>”What the!?”
>Dash clutched at her head
>a horn…
>Twilight said, ”I’m afraid that having handled more power than any living thing in the world *may* have left you a little altered. I hope you’re not too unhappy resuming your duties as Princess Rainbow Dash. You’re like me now. An alicorn.”
>Dash glanced at a pitcher of water beside the bed, on a table
>she squinted at it, and it rattled and slowly lifted with a blurry rainbow light, then dropped and scattered water all over the surface
>”Damn it.”
>”Allow me,” Twilight said, and her own pink glow cleaned up the water and deposited it in a nearby potted plant
>she then poured Dash a glass of water and handed it to her
>”Guess I really was coasting on you guys’ powers, huh?” Dash said, sighed and climbed out of bed
>everything felt off…
>”Don’t sell yourself short, Dash. Literally.”
>Twilight stood to assist, and Dash looked between her and her friend
>… Twi seemed shorter
>Dash had to be almost six feet tall!
>and… Dash didn’t remember having tits that took a full hand to cup
>her hair flowed and waved like in a gentle breeze as it shined and the colours rippled
>and, *damn*, her arms looked extra swole today

>”You’re a freshly turned alicorn,” Twilight said, “you’re going to grow a great deal in the next few years. And now you have the chance to challenge yourself and learn magic from scratch. The way you learned flight; hard work, commitment and earning every victory!”
>Dash flexed her muscles. “And this boost ain’t bad either! Even if I can’t blast bad guys in the face with magic, I think I could whip their asses the old fashioned way!”
>Dash noticed Twilight was staring
>and then Twi noticed too, blushed and cleared her throat awkwardly. “R- right! And of course, I’d be happy to lend you some reading material on the basics of magic.”
>Dash smirked and stepped beside her friend
>she felt more confident than she ever had before, and decided to act on that
>”I dunno about all the geeky, eggheaded stuff like that. You should know me by now!”
>she slapped Twilight’s ample ass with a squeak from the fully fledged princess of friendship, then Dash wrapped an arm and a wing around her mentor
>”I’m a lot more hands on…”
>Twilight blushed, giggled and added, “p- point taken. And maybe it’s because I literally watched just one of your tectonic-plate sized abs grind against Equestria, then your… um, private ‘petals’ almost engulfing the whole world…”
>Twilight turned increasingly red as she started fiddling with her fingers
>”and my then-ditzy mind imprinted that image inside, and left a whole bunch of lewd thoughts, but… do you want to… maybe…”
>Twilight stammered and sweated
>”Go out? Have dinner some time?” Dash leaned in closer, and whispered, “have intense, princess on princess sex?”
>Twilight was practically glowing red as she stuttered, “I- I was going to s- say have a private study session, b- but…”
>Dash pulled Twilight in and kissed her
>on parting, there was a moment of simple staring as they both realised everything would change
>and in a good way…
>”I’ll take that as a yes,” Dash said. “After all, you’re almost as awesome as I am, so it’s only fitting.”
>Twilight smiled and nodded. “No complaints here.”
>they headed out the room together
>Dash stopped and asked, ”what happened to bug-butt?”
>Twilight smirked and said, “well…”
—
>Chrysalis sat in her throne
>her subjects were gathered, and waiting
>”I have been, for too long, uncaring of your needs. As a hive, we must all do our part for the betterment of our community.”
>deep down, she hated these feelings
>the knowledge of Twilight, the empathy of Cadance, the sense of duty of Celestia and the confidence of knowing right and wrong of Luna
>but while each was diminished, they were still within her
>the newest and strongest of these, though, was from Princess Dash
>loyalty, as expected
>but also a sense of compassion, and duty, to strive to do better and be better
>and they were her children
>Chrysalis would do the right thing for them, if only to ease the nagging within herself
>and so she would become a better queen
>whether she liked it or not
The end

*EXTRA*
>Twilight smiled with satisfaction as she finished her letters for the day
>she stretched her subtly toned, 7’5” and full figured body and magicked away her paperwork with a glow of her horn and a wave of her hand
>a princesses job never stopped
>but she was happier than ever to fulfil them
>as the past year, she felt closer to her former mentor than ever before
>firstly, as she undertook more responsibilities, Twilight felt ever-closer to being the heir Celestia wanted
>secondly, as her powers grew from strength to strength, she felt like she was fulfilling her potential, but sitting down and doing the simple, menial things helped keep her grounded
>third, and by no means least, she had a partner
>sort of like Luna to her Celestia
>she loved her partner too
>just in a less… familial sense
>and a far more exciting one
>she heard a distant rumble, like thunder
>Twilight smirked and licked her lips
>the room shook
>she sighed and called out, “you realise you can teleport, right?”
>”Teleporting’s cool, flying’s just cooler!”
>Princess Rainbow Dash entered
>the 6’11” powerhouse princess winked at Twilight, who blushed and felt her heart flutter
>Dash was still developing, but her muscular guild and solid curves danced through Twilight’s mind even when she wasn’t around
>you would think a year would be enough to settle in, normalise their new relationship
>but no; Twilight snared Dash with her magic and pulled her close into a deep, deep cuddle
>”Everything go okay with the dragons?”
>Dash then picked Twilight up, and dipped her down and leaned down over her, like they were dancing
>”Of course it did! I asked them to stop being jerks to the griffons, they argued and challenged me to a fight. I kicked their best warrior’s scaly tail in a duel and we made an agreement. I got this Princess business stuff down, Twi, quit worrying.”
>Twilight giggled and caressed Dash’s cheek. “I know, sorry. I wasn’t doubting you… though I *have* missed you…”
>Dash brought Twilight up and twirled her out, then spun her back into an embrace, complete with wing hug
>”All the more reason I get my work done quicker,”
>Dash used her wing-hug to cover her movements, snaking a hand down and squeezing Twilight’s hip, then stroking back to her big, perfectly pliable ass
>”I’m all done for today as well,” Twilight purred. “And it’s not even dark out yet… oh, whatever will we be forced to do for entertainment?”
>Dash grinned and gave Twilight the deepest, hungriest eyes
>Twilight ran her hands over Dash’s broad, powerful shoulders, each cord of muscle subtly flexing and shifting under her fingertips
>the two princesses could feel each others breath wafting on one another’s faces
>their hearts quickened and thundered

>Dash relented first; with a rainbow coloured glow of her horn, all the windows and doors shut and locked
>and Twilight teleported them onto the bed with a pink flash
>she went to remove their clothes, only for Dash to pinch Twilight’s horn
>”Nuh-uh. This is more fun.”
>she then gripped Twilight’s dress and ripped it apart, exposing Twi’s full, heavy yet perky head-sized tits
>Dash licked her lips as she watched them wobble and settle, then buried her face in them
>Twilight tittered and held Dash’s head against them, and revelled in the kisses, licks and strokes
>Dash then pulled one to her, suckling in and nibbling Twilight’s nipple
>”Oh sweet Celestia,” Twilight whimpered
>Dash smirked up at her, “Still thinkin’ of her, huh? Guess I gotta work harder…”
>Dash slipped lower, running her tongue along Twilight’s smooth, toned belly
>her arms encircled Twi’s legs and pulled them up and over Dash’s shoulders, and her face inches from her goal
>Twi was wet already
>Dash smirked; yeah, she had that effect on her, and it only stoked *and* stroked her ego
>she plunged in deep, taking long laps of her tongue on Twi’s parted eager lips
>Twilight moaned, unrestrained, and wriggled
>her legs struggled against Dash’s arms, but she was too strong
>and maybe a further demonstration of her strength was in order… to assert herself and make things more challenging
>Dash put her knees beneath herself, then keeping Twi pinned and her legs hooked, took Twilight’s hands in hers
>she then lifted Twi in a reverse shoulder sitting position, Dash’s face still buried in Twi’s crotch, and pressed her against the wall and resumed licking
>it was difficult; keeping balance, keeping Twilight supported just right, and getting in deep, penetrating plunges of her tongue
>but the difficultly was what made it hotter!
>”Das-…mmh!” Twi cried out, her eyes rolling back into her head as she was driven to . “Dash! I’m cu…mmiiII AHH!”
>Dash grinned as her lover gushed all over her face, and she kept Twi supported as she slouched against the wall and down harder in Dash’s shoulders as she panted and smiled
>”That good for ya?” Dash asked as she admired the brief mindless expression on Twilight’s face 
>”Uh-huh,” Twilight managed, then the intellect began to seek back in as her horn glowed pink. “Payback time…”
>Dash cocked an eyebrow, then felt something pull on her legs
>Twilight fell on the bed as Dash felt her limbs pulled out like she was on a torture wrack; far enough to stop her moving, but not enough to cause pain
>Dash was held upside down as Twilight climbed to her feet, first wiping her own love-juices from Dash’s face, then caressing and kissing her
>”C’mon, Twilight… lemme go! I wasn’t done yet!”
>”Hey, you dominate me physically, I get to dominate you magically. You know the play by now.”
>Dash went to complain, only for Twilight’s magic to vibrate between her legs and force a gasp

>the quivering shape began to slide into Dash, inch by inch, until it filled her and began to expand, stretching Dash to her limits as she gibbered and tried to struggle free
>Dash then used her magic to attack the telekinetic restraints
>focusing all her power on one hold allowed her to break one limb free, but it was immediately restored the second Dash tried to fight back
>then she ran out of time as the magic filling her slit violently quaked and trembled every inch of her body
>Dash screamed in absolute pleasure, and the will to fight sapped away
>she climaxed in seconds
>and again
>and again
>over and over until she blacked out
>she woke up in Twilight’s arms, with her calmly stroking Dash’s back and smiling at her
>it would usually be comforting, but Dash grumbled
>Twilight’s comforting ”Hey, Dashie, what’s wrong?”
>”It’s not like I didn’t enjoy it, but I’m getting tired of you just dominating me win your stronger magic! What happened to snuggling?”
>Twilight sighed. “You mean wrestling, which you’re considerably better at, on top of being way stronger than me.”
>”At least you get to fight back,” Dash said
>”You could fight back too if you spent some time mastering your magic instead of just using your physicality. You pick up on spells quickly, Rainbow, but you don’t want to put in the time to *truly* strengthen your mind.”
>”It’s eggheaded! I ain’t built like that. I prefer to *do* rather than read those boring books. C’mon, Twilight, there’s gotta be something I can do to get better at magic that isn’t like watching paint dry.”
>Twilight pouted. “They *are* interesting if you’ll just give them a try. Whatever, I suppose we could try a type of arcane… flexing. A test of magical might.”
>Dash sat up and smirked. “Now you’re talking! What’s involved?”
>Twilight sat and crossed her legs, and beckoned Dash to do the same
>”It’s simple; we *push* each other’s magic. No objects, no bodily contact. You simply try to move my field of magic back, and I resist. You get to more firmly apply force in your magic without anyone getting g hurt. Simple as that. It’s not as quick as just *reading a book* but it is more direct.”
>Twilight’s horn glowed, and a pink field formed over her head
>Dash focused on the cloud, and her horn flashed in its rainbow colours as she summoned a similar shimmering field over her head, then moved it into Twilight’s aura
>Twilight sat, calm and controlled
>Dash looked tense, then frowned, then gritted her teeth and strained

>”Easy, Dash. It’s like any other exercise. Build gradually into it.”
>”And let you… grr… reinforce your defences? You wish! I’m gonna kick your butt, magically, right here, right… *now*!”
>Twilight began to have to strain too, but Dash was red in the face and-
>”Dash, your nose is bleeding! Calm down!”
>Dash clenched her eyes shut and kept pushing
>Twilight retracted her magic
>but rather than just stop, Dash pushed even more
>the rainbow field of her magic slammed into Twilight’s horn, and both princesses cried out as Dash’s magic began to forcefully flow into Twilight
>all the while, Dash’s powerful, tall body dwindled, shrank and reduced
>until the towering 7’5 Twilight rubbed her head, and looked way down at the 5’2, slim but toned and de-powered Rainbow Dash

>Dash stared down at her classic body again in shock
>”What the hell!? No!”
>Twilight shook the fuzz from her mind and looked Dash over, gently holding the stunned smaller woman close, and wiping her strain-induced bloody nose clean
>she gently felt around Dash’s forehead, and sighed with relief as the barest hint of a horn was still there
>”Well, you’re still an alicorn,” she said
>”Barely! I’m tiny!”
>”You’re basically the same size as you were as a pegasus, Rainbow. You know… compact?”
>Twilight felt her own horn, which briefly crackled with pink, then an aftershock of rainbow light
>”Looks like you’ve got my magic, at least,” Dash said, “can’t you just give it back?”
>”This shouldn’t have happened, or even be possible, with simple telekinesis! The only time I’ve ever seen this happen was when the other princesses gave me their power to hide it from Lord Tirek, and that was a specific spell. Though I suppose it couldn’t hurt to try.”
>Twilight focused her magic on Dash’s smaller horn, and tried to focus
>but nothing happened, even as Twilight applied more force, to the point Dash grunted in pain
>”There must be some other element at play,” Twilight said and climbed off the bed. “Let’s see…”
>she magicked a nightgown around her, then pulling a few books off the shelf and opening the first as she began to scan through them
>Dash sighed with frustration and moped for a while, before also standing and looking at herself in the mirror
>the narrow, if hard, grooved abdomen, the corded but slim legs and arms, the barely-present boobs…
>”Ugh… I look pathetic.”
>Twilight looked over her shoulder with a reassuring smile as Dash put on one of her vests, now closer to a dress as it dwarfed her tiny body
>”You’re still girl I fell in love with, Rainbow.”
>”Yeah, just a considerably less cool! I’m about 60% less cool! And 30% less awesome! I’m 10% the woman I should be!”
>”No, you’re not.”
>Twilight stood and held Dash close, resting her chin on her head and accidentally smothering her face in her breasts
>”You’re still the hero that fought and saved me from Chrysalis, back during the whole Seed of Supplanted Sorcery event, even while you were wounded and didn’t even have magic.”
>Dash couldn’t help but feel reassured
>she didn’t even mind feeling a little smothered
>Twilight meant the world to her
>even if she felt… increasingly afraid for some reason

>Twilight continued to cuddle Dash, only to gasp
>Dash went to ask what was wrong, only for her already boob-smothered face to get even deeper into the dark, warm cleavage
>”Wh- what the!?”
>Twilight stood and stepped away
>Dash watched as Twilight’s tits strained the nightgown
>then, with a grunt, her body sprouted taller, soon pushing 8ft
>Dash couldn’t help but blush at her towering girlfriend, as Twi looked over her new, enhanced curves
>”This really is like that seed situation again… hmm, I wonder…*
>Twilight pulled out an ancient tome, even if it didn’t exactly tell them anything they hadn’t figured out from their adventure, it would at least refresh Twilight’s memory
>it was a curious book… a gift, from Queen Chrysalis, as a token of peace between the Changelings and Equestria, and evidently how Chrysalis learned how to use the seed to begin with
>as Twilight refamiliarised herself with it, Dash fretted
>everything looked so big, and frightening!
>she huddled over and twiddled her fingers
>”T- Twilight? Are you feeling weird too?”
>Twilight looked over her shoulder. “Huh? Not really, I think I know the solution to your de-powering situation though!“
>she stood and began to cast a spell, then suddenly grabbed her head
>the blinked, shook her head, then grinned
>”Yeah, I know how to fix this.”
>Dash stepped back as Twilight eyed the tiny girl like a delicious little morsel
>”But maybe we should hold off on fixing it. We could have some fun. After all….”
>Twilight ran her hands over her body, then giggled as her tits swelled in her hands, and moaned as she grew taller yet again, her nightgown’s shripping and popping filling the air as she rose to 8’7
>”When you look as *sexy* as I do, why not flaunt it a bit? I look *awesome!*”
>Dash gulped
>it really was like the Sorcery Seed thing… part of Dash’s soul had been transferred, too
>Dash’s confidence was now in Twilight!

>Twilight continued to explore her body, then smirked down at Dash
>”And you just look *adorable* in that oversized thing. But as my little toy- uh, *girlfriend*, I want you in something… more revealing.”
>Twilight snapped her fingers, and Dash’s outfit changed to a pair of blue yoga shorts and a… dangerously tight belly shirt
>and another snap, Twilight changed her overburdened night gown to a similarly tight tip that exposed her shoulders and belly, and a short plaid skirt
>”There we go! Muuuch better!”
>Twilight stretched her body and stuck out her chest, then sashayed over to Dash, patting her girlfriend in the head, then she looked down
>Dash stammered and was frozen
>part out of fear, but her red face and the way she licked her lips and gulped betrayed her biggest thoughts
>and they were *big* indeed…
>Twilight tutted. ”Now, this won’t do… I can barely see you over these *amazingly huge* tits… oh, I know.”
>she leaned down and picked Dash up like a toddler, carried her over to the bed and stood her on it
>Dash was at least a little closer to Twilight’s height with the boost, and finally plucked up the courage to try to say something
>but just as she did, Twilight whimpered, moaned and bit her lip
>her head pushed higher as Twi’s face turned pink, and her eyes went unfocused
>her tits bulged, surged and swelled, consuming every spare inch of the stretchy fabric
>her panties became exposed from beneath her tiny skirt, and pressed against Twilight’s wet lips
>her head then hit the ceiling, and after a short grunt of pain and her ducking down, she just giggled as her body continued to grow 
>she went on her knees, and despite her higher platform, Dash was soon overtaken *again* as Twilight stretched higher, and higher
>with a sigh, Twilight finally stopped growing; she had to be over twelve feet tall!
>she hugged Dash against the underside of her breast, that was even head-sized to Twi
>to Dash, it was as big as her whole torso
>”Hehe… and I’m still growing! I’ll tell you what, you can have all my outgrown clothes, *shorty*.”
>Dash gulped, red in the face. “Uh…”
>”Oh, don’t worry. You’ll grow up into them eventually!”
>Twi’s hand dipped down, her fingers splaying across Dash’s body
>her thumb gently pressed into Dash’s petite bust, her fingers stretching long enough to push into her waistband, dipping lower until her nails brushed against the tiny rainbow coloured tuft of her pubic hair
>”Oh my gosh…” Dash uttered and panted. “Your hands…”
>”Pretty big, huh? Imagine what they could do to you…”
>”I… uh…”
>”Actually,” Twilight purred, wrapped her hand around Dash’s side, and picked her up close to her face, like she was going to drink from the tiny, powerless alicorn
>”Why imagine, why contemplate…. when we can get hands on?”

>Twilight kept Dash raised in her hand, while she stroked her petite butt with the other
>the giantess giggled, and tapped it with two fingers, which still made a resounding *slap* as Dash cried out
>just a perfect mix of pain and pleasure 
>Twilight snickered. ”Aww, is widdle Dashie-Washie enjoying this?”
>”N… no…” Dash stammered, unable to look Twilight in the eye
>”Tsk, Tsk… that just won’t do.” Twilight smiled warmly. “If you’re not having fun, then *I’m* not having…“
>her eyes narrowed and the smile turned darker
>”…*as* much fun.”
>Twilight slid her hand down the back of Dash’s yoga shorts, crooking her middle finger between her legs and up, her fingertip tapping against Dash’s wet, tight slit
>”Twilight, please! Y-you-”
>”Please you? Sure!”
>Dash yelped as Twilight now supported Dash’s weight on her single hand, but especially the middle finger
>she then moaned as Twi’s fingertip entered Dash’s pussy with a tiny *squelch*
>her palm coaxed and clenched against Dash’s butt, and it fingers rubbed against Dash’s slim legs
>just to really let the size difference sink in, still supporting Dash on her lewd ‘hand cradle’, Twi then nestled Dash under the overhang of her huge tits
>and rubbed Dash’s slit
>Dash moaned and writhed, but she was pinned
>she doubted with her current strength, even under ideal circumstances, that she could lift *one* of Twilight’s gigantic breasts
>but Twi didn’t relent; her finger rubbed and twitched it inside of her
>Dash pressed her face into the warm, soft and strained-fabric covered boob and climaxed, her scream muffled
>Twilight giggled, making her breast bob and bounce, squeezing Dash’s body with each shift, and she pulled Dash free with her other hand with a little, wet *pop* as her pussy lips left a wet flood of femcum over Twilight’s hand
>”There’s my tiny playmate! Did you have fun?”
>Dash was still too busy riding the afterglow to respond
>Twilight smiled at her wet fingers, and licked them clean as she winked at Dash with lidded, lusty eyes
>”You’re so sweet, like a tiny rainbow cupcake! I could eat you all day…”
>Dash finally recovered enough to whimper, “Twilight… stop! I beg you!”
>Twilight looked confused for a moment
>she blinked, and her eyes flickered Dash’s magenta for a moment and her horn seeped rainbow coloured magic
>but Twi shook her head and the magic reabsorbed into her horn

>”You wanna beg?” Twilight said, as her eyes turned back to their normal lavender shade. “That can be… ah!”
>she then gasped and sputtered up in size yet again
>it was nowhere near as drastic as the last, but Dash’s jaw went slack as she felt Twi’s hand grow around her waist
>and her breasts burst from her top with a dramatic *snap*
>her hips and ass shredded the skirt and her panties, leaving the giantess naked
>and topping out at 16ft tall, already kneeling, her head once more bumped into the ceiling
>Twilight laughed. “I must be *pretty* big to you, huh?”
>Dash nodded, nervously
>the giantess looked down at herself, then cranes her head down to look in the mirror
>”Oh, sweet Cele-“ she stopped and giggled. “oh, sweet *Me* I’m hot! How sexy do you think I am, Dashie?”
>Dash gulped and stammered for a response
>”*Speechlessly* hot!? That’s what I like to hear! Or… *not* hear, I guess. You deserve a reward!”
>Dash was hoisted up and pinned to the ceiling, Twi’s hand splaying out and pinning her
>Twilight opened her mouth wide with a mocking, “aahhh,” like she was about to eat the tiny girl
>her huge tongue ran between her fingers, probing and licking Dash’s arms, legs, exposed belly
>the thick, wet mass snuck under her top, and dragged against her small tits and toyed with Dash’s erect nipples as the tiny girl stifled a moan
>then it moved the other way… and into her waistband
>Dash cried out as the massive tongue pressed against her still drenched slit
>and began lapping
>it was painfully thick
>but while Twi couldn’t get much inside her miniscuke girlfriend, the pressure, the constant slurping, the dragging against Dash’s ‘button’
>Dash panted and writhed against Twilight’s hand, and tried to hold on
>but she once more saw stars, and orgasmed again with a long, high moan
>Twilight carefully brought her down and hugged Dash into the deep canyon of her breasts as the tiny girl recovered
>”Hehee… you all tuckered out, my little playmate? Wanna sleep?”
>Dash couldn’t argue; she could barely think right now
>she just nodded
>Twilight pulled Dash back a little, her smile caring and loving
>another flicker of magenta on her eyes, a blink of rainbow magic around the horn, then the smile became an arrogant, toothy grin
>”Well, too bad; it’s your turn to please *me*!!”
>Twilight dropped Dash onto the bed, her lightweight body bouncing off the mattress, reinforced for their normally powerful alicorn selves

>then Twilight snickered and purposefully fell over like a massive tree, slowly and with enough imposing mass to make Dash scream in fear of being crushed
>Twilight stopped her fall, but her huge, weighty tits smooshed Dash into the mattress
>her senses were bombarded with *everything* Twilight; the subtle musk, weight, smoothness of Twilights tits as they buried her
>the sound of her excited breathing, the low rumble of her subtle giggle
>the pounding is the giantess’ heartbeat
>Dash couldn’t be seen beneath Twilight, just her muffled voice as she pleaded to be let free
>Twi relented, and shuffled up
>her knees straddled the bed, her hands braced against the wall above the headboard of the bed
>and Dash came face to clit with Twilight’s spread, intensely warm, dripping snatch
>her whole head could fit in there!
>then Twilight suddenly moaned
>Dash watched as her gigantic girlfriend smoothly grew once more
>the bed groaned and cracked as Twilight’s thighs swelled
>the long overhang of her smooth belly stretched farther
>Twilight leaned heavier against the wall, her breasts pushing into, then cracking, the surface with their weight
>with a massive, furniture shaking thud, the bed gave way
>Dash’s face was smushed against Twi’s thick, hard clitoris
>Twilight screamed with bliss and shook the room again, the combined growth arousal and clitoral pressure
>Dash’s body was smothered in Twi’s ejaculate
>but far from easing her arousal, Twilight cackled with joy and slammed her quivering lips on Dash’s face, and began to grind against her
>the wreckage of the bed scraped back and forth on the floor as the titanic Twi’s humped Dash
>the tiny alicorn couldn’t do a thing; she was literally just a toy at this point
>all she could do was try to speed things up, so she jammed her arms inside Twilight’s lips for extra sensation, and held her breath as she was squished under the lust-crazed giantess

>the building shook from Twilight’s movements and moans
>Dash continued to hold on for dear life as she was buried deeper and deeper in Twilight’s pussy lips
>but she felt the muscular inner walls clench around her arms as Twi screamed in the most intense orgasm
>the windows rattled, books, pens and other objects vibrated and were knocked off of tables, shelves and more
>and, sliding down as she was dumbstruck by the climax, Twi slumped down onto the bed with a mighty, earth-shaking thud
>Dash was in danger of being crushed again, and slipped free from between Twilight’s legs, bathed in femcum
>the pair just caught their breath in silence, although Twilight rolled onto her back
>even the simple act still shook the ground, but Dash yelped as a thigh several times larger than herself smacked into her and pressed her against the floor
>”Huh? Oh…” Twilight said and giggled, and plucked Dash free, and buried her in the canyon of her cleavage
>”Not bad, Dashie. I’ll give you a B- for effort. Maybe I’ll amend your grade once I’ve taken a second to catch our breath. *MY* toys need to reach a grade of an A before I’ll consider them truly worthy of me, and I’m still eager to try again!”
>Dash could barely move, and the edges of her vision grew dim from her sheer exhaustion, but she felt her panic rising from being subjected to more play from the giantess
>the one saving grace was that her increasingly desperate situation was she was caring less and less about being scared
>so she stared into Twilight’s eyes and forced herself to speak
>”Twilight… I can’t do this any more! Stop it! Please!”
>she felt emboldened by finally saying this, and crawled up until she grabbed Twilight’s cheeks to get closer, to look Twi deeper in the eyes
>”This isn’t you! You’re not this relentless, insatiable or egotistical.”
>Twilight’s eyes lidded and turned magenta, and her horn glowed with rainbow light
>”You used to enjoy our lovemaking, then we’d spend the rest of the night with you talking about your book and me learning about the faster play-by-play because I’m too stubborn to want to read the same stuff. I used to love hearing how excited you’d be about your latest book, just like you’d love listening to me talk about kicking bad-guy butt as I protect Equestria! I’m sorry I didn’t take your advice about mastering my magic… please, Twilight. Come back to me! You’re my precious egghead.”
>Twilight mumbled, “and you’re my stubborn, hard-headed hero…”
>her eyes went wide and the rainbow glow around her horn latched on to Dash’s reduced one, and it began to flow back into the tiny princess

>Dash felt her mind clear, and her heart grow bolder as her thin, tiny body grew one more, rapidly bursting out of her tight clothes as she found her awesomeness levels rising
>and as the last trace of rainbow light left Twilight, her form began to deflate, and it was like the room sighed with relief as the ground recovered from the couple of tons of princess curves reducing down
>Dash watched with a grin as her muscles swelled, her curves bulged and she pushed past 6ft
>Twilight had a much more rapid transformation, as the 20ft giantess’ curves became ‘merely’ huge instead of gigantic, and her height rapidly dwindled until she passed back into normal princess sizes, the. Back to 7’5
>but the biggest change was her expression
>”Oh… oh no… oh my goodness,”
>Twilight watched as Dash was restored to her 6’11, musclebound form, and was relieved
>but the memories of what she had done the last couple of hours dawned on her as she both blushed and looked mortified
>”I’m so sorry, Rainbow! I… I don’t know what came over me!”
>Dash was too relieved to be back to full awesomeness again to be too worried
>that and she understood; she had a major track record of going too far and acting like a jerk, and Twilight had taken that from her
>”Look, I get it, Twi; the power went to your head and maybe you got a tiny piece of that ego you’re always saying I need to keep in check. It’s cool, I-“
>Twilight threw herself at Dash in a tearful hug
>Dash sighed and gave Twilight the comfort she desired, and winced as she felt the trickle of tears on her shoulder as Twi did her best not to sob
>but Dash knew her girlfriend well enough; she just needed a distraction
>”So… you think I’m like the Seed now? Like I can pull power and bits of soul out of people or even push that into others? That’s pretty hardcore.”
>Twilight sniffled and quickly wiped her eyes as she pulled back from the hug
>”So it seems,” Twilight said, her mind spinning asks her emotions took the back seat. “It’s potentially dangerous, as we’ve just witnessed. I suppose mastering basic spells should be secondary until you get a grip on that Supplanting power. The ramifications are both tremendous *and* terrifying!”
>”I am pretty tremendous,” Dash said with a cocksure grin, but then frowned, “but I’ve gotta admit, I’m not really into being terrifying.”
>she remembered when she let her princess status get to her head when she first changed, becoming arrogant of her powers
>and she still remembered that defiant little girl, protecting Canterlot Palace from Dash after she uncaringly caused the city walls to fall
>knowingly she could be a tyrant, or cause *others* to become one after what had just happened to Twi, she was determined; she would *master* this power

>the pair took a nap after their exhaustion of the transformative sex session set in, but as soon as they awoke, and had something to eat, they began
>Dash looked worried. “You sure you wanna do this?”
>”I am,” Twi nodded, “I consider it penance for what I did to you, as well as our connection clearly makes our powers more compatible with one another, thus easier.”
>”I dunno, Twi… you’re asking me to literally pull a chunk of *you* out of your soul!”
>Twi smirked. “Clearly no permanent damage takes place, and I trust you… but the sooner you learn how to control this power of Soul Supplantation, the sooner you’ll be able to use it for good.”
>Dash thought I’d the ramifications and smirked. “Do you think I could… steal powers from bad guys and give’em to our friends?”
>”Theoretically, I suppose you could, although I’m not a fan of stripping people of parts of themselves. It’s unethical, no matter how cruel some people may be.”
>”You saying you’d rather let jerks like Tirek keep trying to break out of Tartarus and attack everyone again rather than, oh I dunno, me giving Applejack a princess power boost so we can have an epic wrestling match where she’s once again my *closest* physical equal?”
>Twi tried to maintain her fair and balanced opinion, but the idea of Applejack and Dash having a princess empowered, muddy, girl-on-girl wrestling match danced across her mind and made her blush
>and Dash *had* made Chrysalis a more peaceful, caring ruler… not friendly with Equestria by any stretch, but she had more reasoned priorities, so technically this could even help Tirek become less monstrous, same with Sombra and other of Equestria’s most dangerous villains
>clearly Rainbow could use other fragments of souls to implant better morals and ideals into others, and if Dash could turn herself into princess thanks to her and Twilight’s bond, and by letting the powers within her take hold, then give the developed excess into others she had bonds with…
>Twilight gasped as she realised the Elements might just all end up as princesses…
>and as much as she knew it would go against the natural order of succession… she couldn’t help but want it
>”W- we’re getting ahead of ourselves,” Twi said and put a pin in that idea; it was something to aspire towards. “For now, take a fragment from me, and we’ll see how this goes. I trust you, Dash.”
>Dash focused, and took a deep breath as she tried to take a fragment of Twilight
Let’s add another tiny CYOA element; we saw ditzy Twi in the original story when Dash took her ‘eggheadedness.’ What aspect of Twilight should Dash steal and take onto herself? 

>Dash took a deep breath and focused
>she knew Twilight really damn well, so she just had to find something to borrow
>but she was a doer, not a thinker… it was so hard to think of what to take…
>Twi was always so eager to dig into new things, even if it might not seem cool, or fun
>Dash wished *she* was like that-
>wait a second…
>Dash grinned as her horn sparked to life, and surrounded Twilight in a field
>and she drew a part… no, *two* parts out of her
>Twilight’s inquisitiveness and her studious nature
>she would borrow these traits until she could copy them into herself as a lesser aspect, then give them back
>although, that would also mean…
>Dash absorbed these aspects, along with a large portion of Twi’s magic, and opened her eyes
>yep, Twilight shrank rapidly down into her old, unicorn size, although kept her alicorn aspects
>meanwhile, Dash felt her mind alter and change
>she *wanted* to know more things, and she suddenly found the idea of sitting down and enjoying a good book (about a cool topic, admittedly, rather than just a Daring Do book) was a really fun idea
>Twilight rubbed her forehead and sighed
>”Guess it’s just a matter of time before I’m *less* for a while. I can’t help but be a little worried about not having full access to… well, *me*.”
>Dash smirked and patted Twilight in the head
>”Chill out, Twi. I’ll look after you.”
>”I’ll bet,” Twilight said, then looked woozy. “I’d ask what you took, but… I suddenly don’t care, I guess?”
>Twilight just shrugged
>”Yep, that sounds about right. Maybe go kick back and relax a bit? How about a nice book about the history of telekinesis?”
>Twilight gave Dash a funny look. “Sounds boring. And too much effort. It’s not like I *need* to know about that.”
>yep, there went Twi’s studiousness and inquisitiveness

>but far from just those traits within her, Dash felt Twi’s magic merging with her own
>Dash gasped softly as she felt her body begin to subtly grow
>her muscles swelled, her height shifted upward and her curves filled out
>she couldn’t help but think of maybe getting a little good natured ‘revenge’
>she glanced down at Twilight and asked, “whaddya think? Pretty impressive, huh?” Dash ran her hand over her abs. “Bet you wanna know how this body feels?”
>Twilight shrugged. “Not really? I’m not *that* curious.”
>Dash huffed and frowned
>”Really?”
>”Yep.”
>Dash even ignored another growth spurt, despite the pleasure she felt. 
>“… well this is anticlimactic. Whatever.”
>Twilight couldn’t help but feel some trepidation as Dash picked the littler princess up, dropped her on the bed
>then pulled off a couple of books, sat down to one side as she had another spurt, and began reading one with a squint, the tiny tome pinched between her index fingers and thumbs
>Twilight blinked, confused. “Oh… for a second there, I thought you was going to have your way with me as a means of revenge for me taking advantage of your weakened state.”
>Dash sighed in frustration and put the tiny book down. “I considered it, but then I thought about how to best manipulate your vulva by telekinesis, and couldn’t help but wonder what the best way to do that would be. Besides, it’s almost morning: we spent all yesterday evening and most of the night having sex. I’m only one princess! Sheesh.”
>Twilight folded her arms and pouted as Dash once again tried to get into her book
>“The sooner you implant those traits and give me back my soul, the better,” Twi grumbled
>Dash gave Twilight a harsh stare over the book for the interruption
>Twilight sighed and just tried to get some more sleep
The end, again.
