Powerful Twilight CYOA

 

----------

 

“Twilight, with Hearts and Hooves Day nearing I wanted to ask you something.”

 

“Yes, Princess?”

 

“This is somewhat embarrassing, but would you...”

 

“Yes?”

 

“...go with m-.”

 

“Yes!”

 

“-y dear sister Luna?”

 

“Ye- wait, what?”

 

“When she was banished the holiday did not yet exist and I want to make things up to her and have her first first Hearts and Hooves Day be special. She’s had some difficulty meeting new people and making connections so if you would kindly go as her date I would ever so appreciate it.”

 

“Er, Princess, I’m flattered, but I’m not sure about dating your sister.”

 

“It would only be for one day. And you did say that you owed me for when I chose to forget about the contents of that letter you sent me accidentally. Wasn’t it was something about my-”

 

“I’ll do it! I’ll absolutely do this for you. How bad can it be? I think Luna and I both have a bit of a connection anyway from Nightmare Night.”

 

“Oh no, I don’t think she’d want to go out with you specifically, Twilight. She’d know it was my doing so we’ll have to pretend you’re someone else for the day. And besides, you don’t quite measure up to what she likes in a woman.”

 

“Wow, okay. I guess I could- hey!”

 

Celestia had tapped Twilight with her hand glowing a golden hue then stepped back. “Sorry, Twilight, I just knew you’d overthink this otherwise. Don’t worry, the changes should be swift.”

 

The girl looked down at herself waiting for something to happen when her flat chest lurched out into two handful sized mounds.

 

“This is what she likes?”

 

“That’s just the start.”

 

Again her breasts surged, pulling tight against her shirt, their size outlined by the bra constricting them and pushing them up against the fabric. Twilight then felt a tightness down below too as her panties began to go somewhere very uncomfortable. Looking down she could see that her butt was no longer flat as it had also been and now seemed more like a shelf behind her. She was thankful that she had a skirt so at least that wouldn’t tear, but she still tried to pull it down and preserve modesty only to see just how long her legs suddenly appeared.

 

“You might want to take you shoes off, Twilight.”

 

Just as Celestia said that she felt her toes begin to press against the ends of her boots and bent over to untie them. In her hurry though she now felt the sheer weight attached to her chest that had continued to balloon and with the sudden shift her little A-cup bra finally snapped away though remained trapped between her breasts and now skin-tight shirt. The unexpected momentum of her chest caused her to tumble forward, but Celestia caught her shoulders and held her in place as she hastily untied her shoes and kicked them off. Twilight grabbed a hold of her chest as she bent back up to keep them from moving in any other unexpected ways.

 

Then she saw that she was staring at Celestia’s chest when she was much more used to staring at her waist.

 

“You look wonderful, Twilight!” Celestia said as she pulled Twilight in for a hug.

 

Twilight blushed at the contact with her face being where it was and then blushed harder when her shirt finally gave up and tore straight up the back leaving her to hold it up with her hands and keep herself covered.

 

“This is what Luna wants? Seriously? Look at me!”

 

“I know, thank you for being such a good student of mine and doing this.”

 

“Well, this’ll take some getting used to. Being, what, over 7 feet tall now? I can’t see my feet, I’ll have to get used to my new centre of gravity, none of my clothes will fit, and I’ll have to live like this for a week until the actual day...” she sighed, “But if this is what Luna wants then I’m okay with it. ”

 

“Actually...”

 

----------

 

What does Celestia say and what changes will happen to Twilight?

 

----------

 

“Actually, she wants someone who can take can take charge and take care of her. Someone to make her feel like a lady. Big, powerful, like a goddess! Because what goddess doesn’t want to have someone even moreso than them once in a while?”

 

“...You’re making me a goddess?”

 

“Only for a few days. I’m sure if it was a permanent change it would make a lot of people unreasonably mad.”

 

“I don’t know,” Twilight said, pressing her chest in as she looked down, trying to see how far away the ground was, “it’s going to be hard enough adapting to these changes. Are you sure this isn’t good enough?”

 

“But Twilight, I need Luna’s day to be perfect for her. I owe her that at least after all these years.”

 

“Well for you, Princess, I- hey!” Twilight cried as Celestia’s hand gripped her breast and golden magic swirled from her body into Twilight’s. As she did so Twilight’s body crept higher and higher, curves increasing all the whille, but more noticeable was the muscle that began to pack onto her otherwise scrawny frame. The softness on her belly tightened into firm abdominals, her arms bulked into hard biceps, and her legs thickened into wide, firm trunks.

 

Whatever little clothing she still had promptly fled her body and as the magic faded she stood there, feeling the energy subside, and felt more than a little awkward that she was now a head taller than her teacher.

 

As Celestia shook herself out of the shock as well she realized she was still gripping Twilight’s breast. “Well, I hope I don’t have too many important, magical royal duties coming up. I think that’s most of it.” She looked at her white gown and tugged at it, noting the slight looseness that wasn’t there before.

 

“Um, Princess? Can I maybe get something to wear for the train ride home?”

 

“Oh, yes, of course. Hopefully there is something from my bedchamber that will fit. Mind your head on the doorframe.”

[Gap in between these posts and me making it a proper CYOA]

 

----------

 

You are Twilight Sparkle the Huge Human. You normally aren’t big, but it turns out that Celestia really needed a date for Luna and default you wasn’t going to cut it. No longer a scrawny nerd, you are now a grand, curvaceous, amazonian nerd. Imbued with Celestia’s power to satisfy Luna’s understandable kink for someone stronger than her you find yourself even larger than she is, being a foot taller than her at 10 feet and with obvious muscular bulk compared to her more motherly figure. Your size is something you are acutely aware of as you walk through Canterlot after your meeting with the princess as the gown of hers that you are wearing is not properly designed for someone of your proportions. Not that you’re about to flash anyone, but you’ve never had something pull across your chest like this before. Heck, you’ve never even had a chest like this before! You’re just thankful that the simple yet obviously expensive white dress doesn’t have any arms you might tear open, but you feel practically naked considering the conservative clothes you would normally wear.

 

You find yourself in Canterlot. You still have a week to go before Hearts and Hooves Day so you’d better get used to it. Now what should you do?

 

 

----------

 

Being Twilight, it’s only natural that in your mind the library is the best choice at the moment. Surely you’d come up with better ways of coping with anxiety, but now was not the time.

 

You had already left the castle and after some overthinking decided that going back there would be weird, but you did know of another library nearby! Though now as you walk through the streets you can feel the stares. You’re not surprised since you are twice the height of everyone, but it’s the way they look at you too. They’re looks you’ve never received before and you’re not sure how to take them. Are they all really staring at your body? Or maybe it’s because you’re walking around barefoot. Darn Celestia’s dainty feet! At least your powers from her seem to include not being bothered by stepping on little pointy rocks.

 

Your much longer stride brings you swiftly to the steps of the Canterlot Public Library. You walk up the steps three at a time and are taken aback by how small the doors look. The castle was opulent and Celestia sized, but this you’ll have to duck to enter. Bending over you push the heavy oak doors open.

 

*Crack!*

 

Being used to giving these thick doors a shove to get open you ended up throwing them right around 180 degrees causing them to bash the wall. Everyone stares at you as you cringe. You step inside and gingerly push the doors back closed, grateful that there is no obvious damage. Thank goodness they stayed on their hinges. Everyone goes back to reading and you exhale in relief as you hope to avoid any more incidents. Now you just need to find-

 

*Creeeaak*

 

As you take a step forward the old wooden floor cries in complaint. It had never done this to you before! But how much pressure were you now subjecting it to? Any effort to figure out how many hundreds of pounds you were due to muscle, height, and the square cube law are marred by the eyes all on you again.

 

“Sorry,” you whisper. They all do their best to ignore you as the floor continues to strain as you step towards the front desk.

 

“Excuse me, I’m looking for books on muscle development, exercise, and nutrition. Could you point me in the right direction?” You figured you needed anything that could help you understand your current situation better and such knowledge would be important for convincing Luna that you are not just a jumped up dork. At the very least you need to know how much you need to feed yourself at this size!

 

“Mmhmm, can I see your library card, Miss...?”

 

You didn’t have pockets so you turn away as you reach down into your deep cleavage. It was a trick Celestia advised you to use. Pulling out your library card you hand it to the lady.

 

In order to not have Luna suspect that this is a setup by her sister she insisted that you take on an alternate identity for this important romantic mission. Who is Twilight going to have to pretend to be?

 

----------

 

“Alright, Moon Singer. Let me help you out.”

 

Twilight was relieved that the new library card worked. If her new identity kept her from withdrawing from libraries she wasn’t sure if she could go through with it!

 

After the nice lady told her where she might look Twilight continued, “And would you happen to tell me where I might find some books on astronomy? Preferably the latest releases, being an astronomer myself.”

 

“Do you work out as you stargaze?”

 

“Uh, yes! Yes I do.”

 

With the information now in your brain you now can to go and find those books. You’ll learn what all your muscles are called and you’ll also get to brush up on your astronomy. You knew enough to correct someone when they incorrectly identified a constellation, but now you had an excuse to do a deep dive. This would be so much fun!

 

You tried to be as careful as possible, though each footstep was still announced by the floor to everyone in the building. At least no one seemed keen to try to tell you off about it. The bigger issue was trying to get through the cramped shelves. At first you tried to get in just walking in normally like you would, but being so darn wide you realized that wouldn’t work. Clearly the solution was to turn sideways! If only your chest wasn’t such a problem. It pressed into the shelves and nearly cleared one of books when you first turned. Unsure what to do and not wanting to have to ask someone to help you since having to say that your “muscles and boobs were just too freaking massive” would be far too embarrassing. Grabbing what you could reach from the aisles was the best you could manage.

 

You still had some time to kill so you plopped your books down on a table while silently happy at how easy it was to carry so many at once. You pulled out the chair at the table and frowned. You’ve sat here many times before and only now do the chairs look awfully flimsy. You didn’t have a great sense of your body yet, but you were pretty certain that your butt wouldn’t even fit on that let alone whether it would take your weight. You pull over a second chair and hope that there isn’t some rule about one chair per patron.

 

The chairs do make some noise, but nothing too bad. And you were right about the one chair, but even with two you feel your ass is right on the edges. You take a book off from your pile and open it up flat on the table in front of you.

 

And you can’t read it.

 

Yes, when you were totally flat this was how you read everything, but now you couldn’t see much past the top margins of the page. You made due with propping the book up against your stack, but it felt weird to read differently after all this time. Or maybe...

 

You pick up the book and plop it on top of your breasts with the spine fitting into your cleavage. It works! And you have enough bust that it probably won’t totally put a crick in your neck! Your giggle obviously annoys everyone and almost jostles the book out from its resting place so you decide that it may be better to check these out and read them another time.

 

----------

 

And so Twilight leaves the library without too much damage. What next?

 

----------

 

While you are ready to go home, you realize that it would be a pretty long trip without something to eat. No harm in stopping for a snack! After all, you do still have a few bits stashed away in a purse that is, of course, handily stored via cleavage.

 

You find the local shop for high quality yet overpriced coffee and baked goods with your heart set on a muffin. Bending down to enter you can’t help but feel like you’re in some sort of model store as if everything were scaled down for artistic effect, but the people around you to scale with everything kind of hurts your brain. It’ll take more than a couple hours to have your mental image of yourself match your new reality.

 

You hope that will happen sooner than later though as you find yourself bumping into people in the lineup. The line moved up and you kicked the guy in front of you when you tried to just take a small step forward and someone else got a face full of butt when you stepped back in response. You resorted to little shuffles forward to keep further incidents to a minimum. Still, being able to hold a whole stack of books under one arm with no effort at all was a perk you were very happy to have. It was almost a worthwhile tradeoff.

 

Finally you make it to the front of the line and stare down at a very nervous looking teen.

 

“Uh, w-what can I get for you, Princess?”

 

You laugh. “Oh, I’m not the Princess. I’m Tw- Sh-, uh...” Oh good. You’ve already forgotten your name. Just move on. “Could I just have a muffin, please?”

 

“O-one muffin? That’s all?”

 

“Just one! Raisin.” All you needed was a little snack before the trip. Something to munch on as you waited at the station.

 

After getting some very wide eyes from him as you reached down your dress for your coin purse you walk away with your muffin only to frown. This is one sad looking muffin. It’s been a while since you’ve been here, have they been cheaping out? ...Or perhaps it’s just your new perspective. But look at it! This hardly counts as even a snack! You bet you could probably eat the whole darn thing in one bite!

 

In your frustration, you do. You feel like you just had a brief power trip in your ability to demolish a muffin like that, but you also really hope that no one noticed. This is like you scarfing down hayburgers all over again.

 

But more importantly you’re still hungry! That didn’t do anything for you. You get back in line as you try to figure out just how many you actually need to eat now. You’ve doubled in size, but a second wouldn’t cut it and then in a way you’ve actually tripled since you’ve grown outwards too, though you have to factor in all the muscle mass which would certainly require a greater caloric intake and since you know you have a much greater magical potential that may also influence your-

 

“M-miss?”

 

You were at the front of the line again now staring off into space as you failed to calculate the number of muffins required to satisfy you.

 

“Just give me all of them!”

 

“All the what?”

 

“I can’t decide, okay?”

 

“Uh, uh, gimme a sec to ring all that up, uuuhhhh...”

 

Uh oh. Could you really sit there and stuff yourself with like thirty something muffins? Something inside you told you yes. However, another part of you also said that you couldn’t pay for even ten something muffins. But you wanted all that food so bad! And it would be totally awkward to go back on your order now!

 

You should have brought that purse full of bits from home since you were coming to Canterlot! Wait, you knew where it was in your house. Could you maybe bring it to you? Teleporting something that far would be impossible normally, but if Celestia really was lending you all this magic then why not take advantage of it.

 

“Just a sec,” you say as you close your eyes and focus, feeling the strands of magic around you, but far brighter than you’d ever seen them before. You reach out with your mind and pull the matter from that part of the universe and bring it to you.

 

‘IOU - Spike’ reads the sheet of paper.

 

You grunt in frustration and crumple the paper in your hand, not even noticing as the pressure pulps it. Nothing seemed to go right today! What else could you do? Maybe- no, that’s... well, it’s not that bad, is it?

 

You focus your mind on the coins in your little changepurse which promptly bursts as the contents quadruple in number. Fortunately you’re able to grab the coins with your magic and levitate them into a nice little pile. This wasn’t really counterfeiting since these weren’t fake copies but actually creations indistinguishable from minted Equestrian coinage. And matter duplication was so difficult that it wasn’t even in the law books so it was legal, right? And with Celestia’s power you had a bit of extra leeway to use it you figured.

 

Or at least that was the justification you had. You’d still probably sheepishly report this to her later since you’d hate to unwittingly inflate the currency. Still, the cloud of muffins you had floating behind you in a soft purple glow felt totally worth it.

 

----------

 

You begin making your way to the train. You do consider teleporting, but you’re still unused to your body and the image in your mind of you being stuck up to your waist in your home’s floor is enough to dissuade you. You probably wouldn’t but, y’know, what if you did!?

 

As you walk there you feel less insecure since people seem to be more confused by your muffin orb than, well, any other part of you. As such, you decide to have a bit of fun with it and have them orbit around you as would be befitting someone who is supposed to love astronomy. You’ve always had a natural magical dexterity so this would absolutely be something you could do normally, but the sheer ease with which you’re able to move each independently is exciting. Though the challenge rather rapidly becomes less so as orbits degrade and one by one they fall into the atmosphere, er, your waiting mouth. A couple bumped into your boobs too since, you know, you still don’t expect those massive things to be there, but you ignore it since you can’t think of a good way to liken it to an astronomical phenomena.

 

By the time you reach the station your variety of delicious moons are gone and you’re already looking for a food stand of some kind. You really hope that you aren’t always this hungry and assume that the transformation must have left with a caloric deficit. Or something. The health book you were reading on the way didn’t get to that part yet.

 

You resolve to endure the pangs and eat later since the train will arrive soon. You go to buy a ticket, but with how much ass you have you should probably get too tickets. Actually, three. With legs as long as yours you need the room to stretch out.

 

You have just enough left over to purchase the tickets without violating laws of physics and Equestria and soon board the train. You take up three of the four seats in a compartment, but who is it that you find in the fourth seat?

 

----------

 

Choose who will be with her for the ride home!

 

----------

 

As you walk through the centre aisle, hunched over of course, you find your seats and you see- oh crap. Spoiled Rich. You’d recognize her anywhere with her enormous fake breasts, too much makeup, and constantly sour attitude. She was seemingly returning home from buying out a floor of a high end clothing store with her many bags surrounding her on the floor and on the seats you paid for.

 

You approach and smile nervously but she pretends not to notice you and keeps her eyes on her magazine. At the loud creak from the seat it prompts her eyes to glance up and bug out in shock briefly before returning to her lap with a much more determined look of conscious uncaring.

 

You, of course, weren’t going to say anything and didn’t want to move any bags over even if you only had half of your butt actually seated. And you couldn’t stretch your legs with most of the space for your feet being taken up by yet more shopping so you were dreading the cramping you’d feel on this long trip. You couldn’t just ask her to move them after all. She was such a bitch! And you’ve had enough run ins with her in town that you know she doesn’t like you.

 

Wait, you’re not you though. Or at least she doesn’t think you’re you. She’d no doubt have said something if she did. So if you’re not actually ‘Moon Singer’ for now, then maybe she could be a little more...

 

“Pardon me, but would you mind moving your bags?”

 

“Hmm?” Her eyes moved to look at you, but everything else stayed still.

 

“Your bags. I just can’t quiiite fit.”

 

“They’re my seats so they’re staying there.”

 

“Actually,” you said a little louder than you expected as her attitude grated against you, “they’re my seats.”

 

You flash the tickets at her which elicits an indignant huff, but she moves them, even if she makes a big show of it. You are relieved to be able to put your feet down on the opposite seat even if they are still somewhat bent (you can’t put them in the aisle and have them be a hazard!) and eventually you can move over enough that your whole ass gets to rest too.

 

“Ugh, well they’d better not be ruined.”

 

The messy pile of bags on the floor does look pretty bad. You’ll do the nice thing. Maybe that’s who Moon Singer is.

 

“Here, allow me,” you say as you magic up all of her shopping into the air so it hovered above you two.

 

“You’ll really hold that the whole way?”

 

“It’s not hard at all actually. See, you can stretch your feet out too now.”

 

Spoiled Rich merely grunted in response, but she did spread her legs into the freed space.

 

This would be a long train ride. I guess you’ll just see how nice this ‘Moon Singer’ you now were could be to other people.

 

 

----------

 

There was silence between you two for a time as the train rolled on. You took in the sights of the rolling fields of Equestria amidst a sun that was only just beginning its descent. The quiet was uncomfortable though since it wasn’t the ease of two people who didn’t need to say anything, but rather two that were choosing not to say anything. Somehow Spoiled Rich just radiated an aura of bitchiness that was unpleasant to be in the presence of. Maybe you could fix that. Maybe with a fresh face you could see a different side of her!

 

“This is a lovely dress,” you say, floating down the contents of one of her bags. You thought it was actually pretty tacky and with how much it was let out at the front to accommodate her enormous fake breasts it was definitely going to be revealing a lot of them.

 

“Mm,” she muttered, “Sure Stitch does good work. I’m sure he could get someone like you something decent.”

 

Implying that you weren’t already decent. Nice. Okay, perhaps it was undersized, but it was still handmade for the Princess! You couldn’t stand for that.

 

“Oh no, I’m afraid that I’m already very happy with the work of the Princesses’ tailors.”

 

That made her look up and scan your outfit more closely. She flushed in embarrassment a little when she saw the subtle yet unmistakable solar pattern at the bottom of your dress.

 

“Yes it’s... nice. How did you get in with them?”

 

“Oh, I’m, well, I’m their royal astronomer!” You said, making crap up on the spot that sounded good.

 

“Ooh an astronomer. Interesting. I’m a Pisces. That can’t pay much though so it’s nice they let you have their handmedowns.”

 

“Mmhmm,” is the best you can respond with. Just breathe Twilight. Ignore the stupidity and mean comments.

 

“And stop staring. You’re being very rude.”

 

“I- Pardon?”

 

An overmanicured hand touched the top of her breast barely concealed in a tube top that she was about 30 years too old for. At her touch her breast didn’t move at all even with the motion of the train. “You have no right to judge when someone like you has had so much work done yourself.”

 

You were pretty sure you had been doing your best not to look at those overstretched silicone spheres, but she may not be lying since they were pretty distracting. “What? I haven’t had work done.”

 

She let out a nasty snicker. “Uh huh. Not even the Princesses are endowed like that, hon. Or did you borrow those from Celestia too?”

 

“They’re natural! See how they actually move when I do?” You said, shifting side to side to demonstrate their significant wobble.

 

She flushed again. “I don’t see the difference.”

 

“Ugh! Here, let me show you then!”

 

Before you knew it the spell was cast and her breasts sunk down. No longer perfectly round and looking bolted on they had weight to them as the fat inside moulded around the fabric and bulged out of the top.

 

“What did you do!?”

 

“Now do you feel the difference? You’re welcome.”

 

She stared at them in shock, hefting them and letting them fall, feeling natural breast for the first time in what had to have been decades. The shock turned to happiness briefly, the first time you’d seen her like that, then back to her normal constant annoyance with everything in the world.

 

“Well now you’ve got to fix my clothes.”

 

“Pardon?”

 

“Well my breasts are a totally different shape now so it’s all going to look awful. Fix it!”

 

“You do nothing but insult me and when I make you no longer look like a freak you still go out of your way to treat me like this?”

 

“Oh, I have done no such thing. I call things as I see them and if you can’t take it then that’s your problem. Now you’d better take responsibility and fix this problem you’ve created. If you’ve got so much fancy magic this shouldn’t be a problem.”

 

You felt your vision blur. “You’re right! How about I solve this problem right now!”

 

With a magic jingle her top flopped loosely onto her lap because there was nothing left to hold it up. She couldn’t do much other than stare in horror at her now utterly flat chest.

 

“W-what did you do!?”

 

“You don’t have to worry about them anymore. There, problem fixed. Oh wait! It looks like these clothes still won’t fit! Here, I’ll fix that too!”

 

The bags of clothes you were still holding pinged away and you realized that you put way too much force into the teleportation spell. You had been hoping to dramatically scatter them to the winds where she could see them, but they were well past the horizon now.

 

“There, your clothes have been donated to a village in Zebrica. Congratulations! Your problem is solved and you gave something away for free for the first time in your life!”

 

You stood up to leave only for your strong exit to be marred by you banging your head on the ceiling. Ooh, that’s a crack in it. Hopefully no one notices.

 

“If you need me I’ll be in the food car. I hope Diamond Tiara’s bras aren’t too big for you now!”

 

You walked away and gradually calmed yourself. That was pretty harsh, but she deserved it, right? Right?

 

----------

 

Now Twilight is going to make it back to Ponyville so what should she do when she gets there?

 

----------

 

Finally, back in Ponyville. Odd name considering you’re all humans, but it’s your home nonetheless. Of all the things you’re looking forward to it’s currently getting a nice big meal ready since the food car really was not that great. Of course, Pinkie would probably recognize you instantly considering how good she was with people. Wait, everyone knew you well here so what were the chances that more would know who she was even with such a change in your body? And what if they know and blow your cover and ruin Luna’s date! Perhaps it would be safer to visit Rarity for a quick makeover. Something to change up your look and maybe a new hair style would solve things.

 

So you begin to make your way there , trying to be subtle and go around houses away from main streets just in case, but unsurprisingly being 10 feet tall and built like you are makes that really frigging hard. After one too many close calls with some confused looking townsfolk you decide you have to risk it. You’re going to teleport.

 

You focus your mind, knowing the location you’ve visited so many times all too well. You focus on the grass outside, raising yourself so you don’t have to dig yourself out of the ground, and-

 

Thud.

 

A couple feet too high.

 

It didn’t hurt, but it was enough that you can hear Rarity’s heels already clacking against the tile of her boutique as she hurries to the noise and the door soon opens with a dingle from the entry bell.

 

“Goodness what was that- Twilight?”

 

“Er, hey Rarity. I need a new wardrobe.”

 

You reach an arm out as Rarity goes to faint and she recovers briefly only to go limp again after she tries to steady herself and gets a handful of your bicep. You’re able to then carry her in and let her recover on one of her couches as you explain the situation thoroughly. Fortunately she’s understanding and more than happy to begin helping you find something to suit your new you. In fact she’s absolutely thrilled to be working with someone who is so unique in body type. Though you do fear she may wish for you to model things in return for her services and you’re not inclined to refuse.

 

“Okay, Twilight, or should I say, Moon Singer, what kind of look are you going for?”

 

“Um, I didn’t exactly think about that yet. Give me a sec...”

 

----------

 

Alright, what sort of style should Twilight adopt?

 

----------

 

“Well, Twilight, I must say that you look absolutely gorgeous in that dress. I doubt I could do justice to something from the royal palace, but I could work on something in the style of it. Something flowing, palatial, refined.”

 

“Actually, I think I need to look like a jock.”

 

“...I beg your pardon?”

 

“This whole ‘suddenly I’m huge and taking a different name’ is a big favour for Celestia to make sure that Luna’s first ever Hearts and Hooves day is special so I think I need to honour that agreement. Luna wants someone to make her feel like a lady and I think that look would do the job nicely. Besides, I might as well go for something that’s totally different and can show off the new me, right?”

 

As you flex proudly Rarity briefly becomes unable to respond as her eyes lock to your powerful arms. “Er, sure. Yes, I suppose I could do something like that. Perhaps I’ll adjust that dress for a backup, however.”

 

“Alright!” You say as you grab a nearby measuring tape, “Let’s get to measuring!” you cry as you pull the tape taut for dramatic effect only for it to pop in half seemingly having offered no resistance to you. “Ah, sorry, Rarity. I still need a handle on this strength thing.”

 

Rarity proceeds to taking your measurements and does quite a good job hiding her surprise at the numbers that result. She pushes over a small footstool to stand on then thinks better and goes for a chair to get the height she needs, but you’re helpful enough grab her without warning and lift her up instead so she can reach. However, as much as you enjoyed the sensation of holding your friend like a doll she gets you to compromise and just get on your knees instead which you still enjoy when you see that even then she’s only chest height on you.

 

“Okay, I do have some ideas, but I doubt I could get anything ready for you until tomorrow. I take it you’d want something else for right now though? That dress looks in danger of popping off and I don’t think a royal gown quite fits with you trying to look like a normal citizen of Ponyville.”

 

“Oh that’s right! I can’t still have Twilight hair if I’m Moon Singer.”

 

“Ooh how fun! Let me get my things. We can cut it short and style it into something with perhaps a bit of punk flair. Give you a bit of that-”

 

There was a ping of magic and your hair was already changed to be short and swooshing over your head. It still had your distinct colour pattern, but you figured you could change that freely another time. “Like this?”

 

“Oh I thought we were going to... well I suppose that time is of the essence. Yes, that look just fine. Now as for something to wear what were you thinking? I could see about preparing something quickly.”

 

“Maybe something casual? Maybe something like work out clothes since that would make sense for someone built like this. Plus I think these muscles may need to be put to work to keep them from cramping. At least I think that’s what I read. I really need to know more about this stuff.”

 

“Well, er, I don’t think I have anything quite like that, but... hmm, just a second.”

 

She leaves the room and soon returns with light grey yoga pants and a darker grey crop top both of which are hilariously undersized for you.

 

“I’m not suggesting you wear these of course, but something like them. See, Sweetie’s recently been in some sort of health and exercise phase, probably because of her friends, and I whipped these up for her. I wouldn’t call them classy, but I think they’d suit your needs just fine.”

 

“They look perfect! I’ll take them.”

 

“Excellent! Now if you just wait maybe half an hour or, hmm, perhaps it may take longer with so much fabric and your bustline is far from normal so-”

 

“Oh no, these are fine,” you say as you take them from her.

 

“Twilight, are you having a moment of forgetting that you may not be quite able to fit into them as you may have before?”

 

“Don’t worry, I was thinking about this earlier and I have a solution.”

 

With a simple, or simple for you at least, application of magic the top and bottom pulse briefly and you put them aside to take off your dress. Rarity looked away, but you didn’t mind either way. Not like you had a choice since you’re pretty sure you’d reach high enough over a privacy curtain that it wouldn’t actually hide enough to matter. Dropping the dress to the side you take the tiny pants and place your foot down the leg which slides right over it without a sign of tearing. Placing your other leg in with ease the cuffs stay at your ankles and you’re able to pull it up to your waist with it expanding to fit over your legs without any sign of strain or tearing. Your top goes on with similar results though the sight of such unbelievably undersized clothing pulling to fit over such enormous breasts makes you laugh even as your brain hurts at the physics violation.

 

“And I’m all good to go out! And when you’re done with my other clothes I can just give it back good as new. Thank you so much, Rarity.”

 

If she wasn’t speechless before at your body and the magic trick then she definitely was when you pulled her in for a tight, nearly suffocating hug. You made sure to be extra careful when handling other people and since you didn’t hear anything pop you’re pretty sure you succeeded at holding back your strength.

 

“I’d better be off, but if you need me to use that magic on anything for you then just ask!”

 

----------

 

So, where will Twilight go next?

 

----------

 

You needed sustenance. You have begun to suspect that this sudden hunger isn’t entirely the fault of your body, but also your magic. A lot of these spells you can do innately since it’s power you never could have imagined before, but with no practice it was unrefined and probably used up a lot more energy than it should. Hence your desire. A desire that only the best baker in Equestria could satisfy.

 

To fit in with your new outfit you decide to jog your way over to Sugarcube Corner. It feels so effortless yet so exhilarating to get your body moving like this. Though you also almost immediately realized that you can’t wait for a proper sports bra because oh sweet Celestia these things bounce. You never had this problem before for obvious reasons, so this is a very new and initially unwelcome sensation, but you soon grow to enjoy it. You have real boobs now! Huge, bouncing breasts that can’t help but be noticed. Probably the biggest all of Equestria!

 

That mindset actually had you noticing how many of the townsfolk were looking at them. Most would pay you no mind as you went about your business as your old self, but now their eyes were all over you. You loved it. You had much less love for being unable to see below you, but you had a fix for that issue. With a simple magic aura around your body you ensured that anyone on a collision course for you would automatically move out of the way. It wasn’t so much mind control as it was a sort of mental nudge so it wasn’t anything too morally questionable. It kept anyone from getting hurt and you didn’t have to pay attention to where you were going so everyone wins!

 

It wasn’t long before you entered Sugarcube Corner.

 

“Oh hello there person who is totally new to town!” called Pinkie, “I have never met you before and don’t know who you are, but I look forward to meeting you, whoever you may be.”

 

Her incessant winking at you was similarly unconvincing, but no one else around seemed to pay her mind. Not with you around at least. You approached the counter and introduced yourself.

 

“Hi! I am Moon Singer and I am an astronomer from Canterlot who has come to town for the week. I require your finest baked goods.” Okay, maybe you could stand to work on your acting a bit too.

 

“Good to meet you Miss Singer. You and I should get together some time and I can show you around town,” she said in a very stilted way as she busied herself with decorating a cupcake. “Have this on the house.”

 

On top of the cupcake was writing made with icing that read, ‘Your Super Spy secret identity is safe with me, Twilight. Please destroy this message after reading.’ Wow she was good at piping to get legible text that small. You obliged and consumed it. Oh did that taste good. Did Celestia give you better taste buds? Or were you just that hungry? Whatever the case, you were going to be here for a while.

 

And you were, ordering whatever suited you and consuming them at a rate that made even Pinkie impressed. For her part, she kept giving you more secret messages that you were to consume after reading such as,

‘How did your spy training make you taller?’

‘Are your massive gazongas a part of your disguise?’

‘Can I touch them?’

‘Can I become a tall and busty super spy too?’

 

You made a note to answer these questions later, while maybe ignoring the weirder ones.

 

As you were eating you found that your “gazongas” were causing an unfamiliar problem of getting crumbs trapped in your cleavage. It was uncomfortable to say the least and you tried to brush them out midway through cake number three (they were small cakes, okay?) but didn’t have much luck.

 

“Ooh, here, let me help!” Pinkie said as she hurried to a stool next to you and grabbed the straps of your top and shook them, bouncing your breasts until your cleavage was free from the remains of your food. Oddly, this didn’t bother you. Having breasts big enough to shake was very nice and there being someone willing to do that made you feel very princessly.

 

You could get used to this.

 

----------

 

As good as the food is, you figure that all this sugar probably isn’t the best for you. You’d never had quite the appetite like this, putting away so much and yet still feeling like you could keep going. You excused yourself by telling Pinkie that you had “secret business” to attend to which you figured would keep her mind occupied for a while.

 

The crowd parts as you leave the bakery and you only feel mildly unwell from the amount of sweets in your system so you resolve to have a real meal later. You do feel fully renewed with energy though and are excited to start testing out what your new body can do. And there’s only one person for that job.

 

You make your way through town towards the park since by now Dash should be doing some afternoon workouts. Or sleeping. Walking through the rows of market stalls you realize you’re so tall that you actually can’t see what’s on sale without bending over due to the fabric overhangs obscuring your vision. The fact that you were so tall that you had to move your whole body to see something meant for lesser people was just to enjoyable.

 

Wait, not lesser, you just meant smaller. Yeah.

 

You could run there, but you’d rather wait to have someone to compare yourself to. No sense in working up a sweat until you wanted to push yourself. Instead you just took in the sights until you came upon Dash who was very much asleep. You go to wake her up, but realize that you could probably do something more fun that just calling her name or poking her. In fact, with your awesome new powers you could probably get a good prank in to pay her back for all those other times.

 

----------

 

Why don’t you give her a fun dream to wake her up from. Let’s see if you have dreamwalking powers like Luna!

 

Hmmmm.

 

Hnnnng.

 

HHHRRRNNNGGG!

 

Nope, nothing’s happening. Guess that’s outside of Celestia’s purview. But you are able to implant thoughts into the minds of others so maybe you can liven up Rainbow’s dream anyway. Let’s see, implant the idea of you, perhaps an idea of Dash being bigger...

 

__--**--___--**--__ (Dream effects transition, woo!)

 

Hoo, being such a cool, athletic girl sure is hard sometimes. But making everyone impressed by how totally awesomely you work out is definitely worth it. Just look at all the people who keep sexily admiring your sexy body in all its sexiness. Yes, being Rainbow Dash was fucking awesome because you were so awesome that they would just watch your body in all its glory. You felt yourself-

 

“Hi Rainbow!”

 

Ah! “Oh, hey Twilight. Where did you come from all of a sudden? Don’t normally see you around here.”

 

“That’s right! I’m such an egghead that I have never been in a gym before! But look, I brought this for you!”

 

“Oh wow, a glowy purple sports drink. Is this something you made from your nerd books?”

 

Twilight was now cradling a half dozen books in her arms with titles too long and too fine print to read. “Yes it is. It’s an awesomification potion that multiplies the awesomeness inside person. I had to bring it to you since were I to take it nothing would happen!”

 

“Awesome.” You, without giving any further thought to the strangeness of this situation, drink the thing. It tastes like nothing, but you sure feel something.

 

You now found you were looking down at Twilight. She had always been even more petite than you so this wasn’t unusual, but you were really looking down now. You kept creeping up, looking at the still awed crowed as you could see over more and more heads. You looked at your body and saw your small chest surging outward as it pulled against your sports bra yet it didn’t get uncomfortably tight. Stretching your legs out you saw what had been lean runner’s muscles bulk out into wide, thick cords with each muscle defined tightly against your skin. Abs, biceps, boobs, butt, you kept darting your eyes and hands between each of them. It didn’t feel real.

 

The crowd was oddly silent, but Twilight was still there to flex at.

 

“Wow, Rainbow, you’re awesome! Or, should I say, awesomer!” Hey, she said that word that she claimed didn’t exist last week. Glad she’s seen the light.

 

You turn to the gym equipment to play with that more now that you have so much more of you to work out with, but as you turn Twilight’s sitting on the bench press. Wow she moves fast. And why does she look so good? That’s weird though, Twilight’s cute, but she’s not your type. You’re not interested in-

 

You’re suddenly very interested in Twilight.

 

“Come here, Rainbow, you big stud,” she said as she balanced perfectly on the racked barbell so she could be closer to eye level and lean against your hard shoulder. “Show me a good time and I’ll admit I was wrong when I said that Daring Do is written for a fourth grade reading level.”

 

You took a hold of Twilight, so small and light now that she could sit with her butt planted on your hand like it was nothing. You brought her lips to yours...

 

__--**--___--**--__

 

You, Twilight, see the sleeping dash not sleeping quite as easily. Whatever you implanted in there she’s writhing around a bit and making quiet little noises. They sound good though, like she’s having far too good a time with whatever’s in that brain of hers.
