The Wagered World

“Well?” said Twilight, smiling encouragingly as the former royals stepped into the throne room. “I think you look amazing, but if there’s anything you’d like to change, I can take care of that for you.”

“These dresses are lovely, Twilight, but…” Luna let out a little sigh.

“They are rather similar to the dresses worn by chancellors in our royal court,” said Celestia. “I assume that is intentional. To remind us that we are… no longer princesses.”

“Well, I don’t mean it as an insult,” said Twilight. “But you lost the bet fair and square. You’re still important and respected, you’re just not princesses.”

“We knew the stakes,” said Celestia. “It’s a bit of an adjustment, is all.”

Twilight slumped in her throne, making her immense tits wobble in her lap. “Well, this is a bummer,” said Twilight. “I was excited to share all the good news about Equestria, but your demotion isn’t the happiest topic, is it?”

“The prosperity of Equestria is what truly matters, I suppose” said Luna. “And this is better than the last time I got demoted. From princess to prisoner.”

“Oof,” muttered Twilight. “Another bummer. Maybe I should have let Pinkie plan your welcome; without her, it’s up to me to turn this mood around…” She sat up - and her giant tits shook again. “Oh, I know! Chrysalis! Umbra!”

When Twilight spoke the names, wide circles of purple magic appeared on either side of her throne. She looked at one, then the other, peering expectantly at them - then, after several seconds of silence, she sighed and rolled her eyes. “Sorry,” she said, “They’re still very… proud. They like to make me wait. I do what I can to incentivize their cooperation, but building trust has been a slow-”

The magic circle on Twilight’s left began to glow brighter, and a second later the one on the right did the same. They expanded into columns of purple light - and when the columns faded, a pony stood where each one had been.

On Twilight’s left was Chrysalis. The deposed changeling queen was more voluptuous than Celestia and Luna remembered her being - not as outrageously proportioned as Queen Twilight Sparkle, but her breasts were F-cups at least and her hips were deliciously thick.

On Twilight’s right was… Umbra? Not a name the former princesses recognized, but the tall, dark gray pony was immediately recognizable as King Sombra. No other pony had that sharp red horn, or those green-and-red eyes, tainted with dark magic… but those features didn’t usually sit on a face that was so soft, atop a body so entirely feminine.
“Oh,” muttered Umbra, “They’re back.”

Chrysalis smirked. “Umbra, don’t be a bitch. I’m sure we’ll all be the best of friends in no time at all.”

“Hey, that’s the spirit!” said Twilight. “Only next time try it with about a hundred percent less sarcasm.” She turned to Chrysalis and Luna, extending her arms to indicate the ponies on either side of her. “Chrysalis and Umbra here are part of a sort of… work-release redemption program. A slightly more formalized version of the way I used to reform villains.

“Chrysalis works with our military and intelligence operations, including S.M.I.L.E. She has… lots of experience in espionage and intelligence-gathering. More experience than anyone suspected, I think.” Chrysalis’ thin smile became a toothy grin at the mention of her clandestine exploits.

“And Umbra - who you know as King Sombra… Uh, funny story there, actually. We wanted to bring Sombra back, with limits on his powers of course, and there was some… cross-pollination with the gender-changing magic we were studying. Sombra came back in a female body, and it was a little tricky to fix it…”

“And by the time she figured out a fix,” Umbra cut in, “I was actually fairly comfortable in this body.”

“It’s not a bad body, I must admit,” said Luna, muttering softly enough that only her sister could hear.

“Umbra’s role is more internal,” said Twilight. “She’s good at keeping track of money - and she’s partially responsible for reports on the various social classes are responding to the ongoing social changes. We’ve seen a lot of change in the last five years, quicker and more broad than Equestria has any precedent for.”

Celestia raised an eyebrow. “And you trust them with these tasks?”

“Oh, there’s loads of oversight,” said Twilight. “If they step out of line, they know what’ll happen.” She hopped down from the throne, casually strolling towards the sisters, the bulge of her cock and balls swaying beneath her dark dress. Anyway, I called them here for the second part of your makeover - a part I think you’ll enjoy!”

Twilight walked right up to Celestia - and the sight of her former student’s tits in her face reminded her of just how big Twilight had grown. Celestia was staring straight into the deep purple shadows of Twilight’s cleavage, and sight was… enticing. “A lot of ponies have had their bodies altered,” said Twilight. “The basic alteration, which is sort of required… or at least strongly encouraged… just makes your body more durable and stretchy. It’s a useful little enchantment, but the malleable body also creates the opportunity for more interesting changes.”

“So we can change our appearance?” asked Luna. “As you have done?”

“Not just me,” said Twilight. “This magic has been made available to all ponies, by mass-producing dark crystals imbued with changeling magic. But for you two, we can get that magic straight from the source. And you can look however you want. If anything about my body inspires you,” she said, shaking her shoulders to wobble her giant tits, “then feel free to copy off my work. I look forward to seeing what you come up with.”

“Oh my,” said Celestia, practically mesmerized by Twilight’s breasts. “I wouldn’t really know what to say to that, Twilight. You may have cast off your modesty, but I don’t know if I’m ready to transform myself in that way.”

“Oh, that won’t be a problem,” said Chrysalis, taking a step forward. “Our magic changes you from within… and if you allow it to, it can reach your deepest fantasies. Whether you realize it or not, there is a perfect body that you desire… and if you just open your mind a bit, the magic will mold you into precisely that shape.”

“Yes, I think you’ll be happy with the results!” said Twilight. “And it’s nothing to be nervous about, Celestia. You’ll be in control the whole time, so it won’t go outside your comfort zone.”

“Well… I suppose I do need to fit in with this new world,” said Celestia. “Very well. Change me.”

Twilight stepped back, and Chrysalis and Umbra stepped forward, until all of them were giving Celestia a good five feet of space. Chrysalis and Umbra activated their magic, both sending a flare of energy into Celestia’s body. As the magic hit her, she noticed a change in her body… it felt looser, and she felt instinctively that she could mold it into a different shape with nothing but her will. Her clothes faded into nothingness, and she was a bit surprised to find herself naked… but the feeling in her body was so good, and so comfortable, that it didn’t bother her.

“Why don’t you talk us through your thought process, Celestia?” asked Chrysalis, running her tongue over her lips. “Let desire bubble to the surface… and fearlessly tell us what you want to become.”

“I’d like to be… taller… like Twilight,” said Celestia. “I always liked being the tallest pony around.” As soon as she spoke, she felt herself growing, her body stretching upwards. “Oh, that feels good…”

“It always feels good to get bigger,” said Chrysalis. “Surely that’s not all you want, is it? The spell can make you grow much more.”

“Well, as long as I can have whatever I wish,” said Celestia, “Perhaps a little more muscle definition?” Muscle firmed up all over her body; up and down her arms and legs, toned muscle formed beneath the skin. Biceps swelled, thighs widened, and her smooth belly grew a set of six-pack abs... and between her height and her muscle, she was every inch an amazon.

“Please tell me you want those tits to grow,” said Chrysalis. “You’ve got a great rack, Celly, but they’re pretty shrimpy by modern standard. I want to see those boobs inflate like hot-air balloons.”

“Oh, you want to see these beautiful milk-white breasts blossom into gorgeous globes, changeling queen?” said Celestia, meeting Chrysalis’ eyes. “Well, you’re in luck… Twilight’s tits looked so good, I knew I had to get a pair of my own…” Her breasts grew larger, staying firm but sinking lower as they swelled past cup size after cup size.

“And all this talk of mares with cocks,” continued Celestia, “it sparks a fire in one’s imagination…” From above her pussy, a cock sprouted, along with dangling white ballsack. As it grew, it paused briefly at ten inches - a size at which it looked reasonably proportioned on her amazonian body. She reached a hand down, feeling the smooth flesh of her flaccid shaft, and gasped in pleasure. “Oh, that feels wonderful,” she said, as the growth resumed. “I need to be bigger…”

“Wow,” said Chrysalis. “I was hoping I’d see you grow a nice thick cock, Celestia, but I was expecting I’d have to talk you into it.”

Celestia grinned at Chrysalis, gripping her cock in one hand. By now it was fifteen inches long, and big enough that her fingers couldn’t close around it. “Oh, you were looking forward to this, were you? I wonder why…” She wrapped her other hand around the base of her shaft, stroking it as it grew. “Tell me, did you imagine how it would feel to hold it in your hands? To caress the tip with your tongue?” A surge of growth made it long enough to dangle past her knees, and still it kept growing. “When you imagined getting fucked by the lovely sun princess, how big did you wish for my cock to be, Chrysalis? Because… the more I grow, the more wonderful it feels… I don’t know when I’ll feel like stopping.”

True to her word, Celestia let herself grow bigger and bigger, her marble-white cock growing and thickening inch by inch and foot by foot. The tip of her cock hit the floor and kept growing, snaking in Chrysalis’ direction as it lengthened. It swelled wider than her muscular thigh, then wider than her waist, then bigger around than her gigantic bust.

And as it grew, it stiffened, rising from the floor. Celestia shuffled her feet apart, making space for balls that were now bigger from her tits and hanging down to her ankles. Chrysalis stared wide-eyed at the giant shaft that was growing in her direction, rising higher until it pointed right at her crotch. “Woah,” she said, “Celly, you’re huge.”

“Not huge enough,” said Celestia, now stroking as much of her cock as she could reach. “Don’t you want to see this cock grow even bigger?”

“Geez, Celly, you’re going nuts, aren’t you?” laughed Chrysalis. The three-foot-thick head of Celestia’s cock was closing in on her, and she intercepted it with both hands, wrapping her slender black fingers around its rim and walking backwards as it continued to grow longer. “I think… Twilight, is this the biggest dick in Equestria?”

“Not quite,” said Twilight, eyeing the huge shaft as it grew. Her own cock was slowly stiffening, lifting the front of her skirt. “Not… quite… but… Okay, now it is.”

“Oh really?” said Celestia, looking down the length of her nine-foot cock. “Well… perhaps I can stop there, then.” Her growth halted, and the loose feeling in her body went away as it settled into its new shape. “You were right, Twilight, this did improve my mood. Having the world’s biggest cock does wonders for one’s self-esteem. Although… I could see it being a bit impractical, swinging around an erection this large. Could my clothes perhaps be enchanted to manage its size?”

“Of course, of course!” said Twilight. “Luna, how about you?”

“Oh, I am more than ready,” said Luna. “I didn’t wish to pressure my sister, but I shared none of her earlier doubts. By all means, change me. I wish to grow.”

Chrysalis and Umbra nodded at each other and cast the spell again. Once her clothes disappeared, Luna started to grow taller and more curvaceous, her tits and ass getting wider and rounder at a fantastic pace. “Oh, I’ve seen this before,” muttered Umbra. “You’re a growth slut right from the word go, aren’t you?”

“What, are you afraid I will end up with a body that makes you jealous?” teased Luna. “Do not worry - I assure you that my form will drive you mad with envy and lust.” Her breasts grew until they hung down to her belly button, and then they stopped - but her ass kept right on growing.

Umbra watched Luna’s moons grow wider than her shoulders, scoffing in disbelief. “You’re going to have a hard time finding a place to sit, moon mare, if you continue to let your bottom expand like that.”

“Oh, I think I could find someplace comfortable enough,” said Luna. “Your face looks like an inviting seat…” She clapped her hands onto her immense asscheeks, and they began to grow faster. “Or perhaps I could grow so large that my bottom engulfs your entire body? Yes, that sounds like a lovely time…” she turned to Twilight. “Twilight, do I have the biggest rump in Equestria yet, or should I give it a few more minutes?”

“I’m pretty sure you’re the biggest,” said Twilight - and Luna, now sporting an ass almost as wide as she was tall, stopped growing. “Umbra’s right, though. Chairs might be a problem for you… doorways, too.”

“Perhaps my clothes could be enchanted to manage the size of my ass, then?” said Luna. “Speaking of managing things, Twilight, it seems that our changes have had a salutary effect on your mood as well.” She pointed a finger at Twilight’s dress, where the Queen’s cock was tenting the material something fierce.

“Yeah, after watching two of the hottest ponies in Equestria get even hotter, I definitely need to drain my balls,” said Twilight, reaching down to grope herself. “Fortunately, I have someone on staff to help me deal with that. Barb?”

Twilight spoke the word “Barb” into the empty air, barely raising her voice - but there must have been some kind of magic that caused the request to hit the proper ears, because not five seconds later a door in the back wall of the throne room opened up and a purple-and-green dragoness entered the room.

“Spike?” asked Celestia. The dragoness was fully grown, with scaly cleavage peeking out from a white button-down shirt, emerald eyes behind a thin pair of spectacles, and luscious legs beneath a short black pencil skirt… but it had to be the same little dragon Celestia knew from before.

“Princess Celestia!” said the dragoness excitedly. “Princess Luna! It’s so good to see you! It’s Barb, now, actually - my name, I mean…” She walked towards the sisters, ready to embrace them… but Twilight grabbed her by her shoulder, bringing her to a halt.

“Did you forget?” said Twilight, leaning down to bring her lips right to Barb’s ear. “They’re not princesses anymore. The only royal in this palace is Queen Mommy. And Queen Mommy needs to empty her balls into her sexy secretary…”

“Sure thing!” said Barb, tugging down her skirt and falling to her knees. “I bet you’ve got a pretty big load for me, if you just watched Celestia and Luna transform. Luna, you’ve got an incredible butt now, and Celestia… I’ve never seen a cock so big!”

“Only one cock you need to concern yourself with now,” said Twilight. With a flicker of magic from the tip of her horn, her clothes vanished - and it seemed that her clothes had possessed the cock-minimizing magic that Celestia had requested, because the hard dick that sprang forth was a good five feet long. “Your mother’s cock is nice and hard, and her balls are bursting with cum… and she needs you to take every drop for her.”

“With pleasure!” said Spike, unbuttoning her shirt and exposing her scaly tits. “By the way I’ve got a date with Ember this evening… but I have plenty of time for you, mom.”

“Goodness,” said Celestia, seeming uneasy. “It did always seem to me that you had a maternal relationship with… Barb. And I wouldn’t expect that that would go in a… sexual direction.”

“Oh, right, I suppose this would be a surprise,” said Twilight. “Sorry, this is just such a normal part of my day that I didn’t think anything of it, but this is as good a time as any to explain this…” She stood several feet behind Barb, who was waiting in a doggy-style position on the throne room floor. “A lot of sexual taboos have been broken down lately. Basically anything two consenting adults want to do with one another is fine… the rise of sexual satisfaction has led to generally healthier relationships, even if some of them are what you might consider unconventional.”

“I suppose you know what’s best for yourselves,” said Celestia.

“We do,” said Twilight, easing her immensely thick cock into Barb’s pussy. “That’s why I’m Queen Mommy. Because I know what’s best for my girl…” Barb’s body visibly stretched as she was penetrated, her hips and then her loser torso growing wider as the monstrous cock slid further into her. “You like your mother’s big hard cock, don’t you, Barb?”

“Yes,” groaned Barb, rolling her hips and clawing at the floor as Twilight embedded another foot of mare meat into her pussy. “Yes, I love your cock, mom… please give me all of it, please fuck me as hard as you can…”

“Mmm, you love to get fucked, don’t you?” said Twilight. “Like mother, like daughter… there’s nothing you love more than a big hard cock deep inside you…” She pumped her hips, driving her cock deeper into Barb’s body, and each stroke was harder and faster than the last.

“Fill me, Queen Mommy!” cried Barb. “Give it to me harder, please, fuck my hot little dragon pussy…” Twilight’s thrusts hammered Barb’s body, and Twilight’s cock stretched her torso all the way to her shoulders.

“That magic really does make ponies stretchy, doesn’t it?” said Luna. “I can’t wait to try that out for myself.” She took a seat on the floor - which, given the size of the butt she was sitting on, left her nearly as tall as she was when she was standing.

“I hadn’t expected her to be quite so rough with Barb,” said Celestia. “That looks like decidedly… angry sex.”

“Oh, that’s normal,” said Chrysalis, sidling up to Celestia. “They both like it rough… and a quick, hard fuck saves time when Twilight just needs to empty her balls. Usually takes a while for her to blow her whole load. And judging by that nine-foot-long boner you’re still swinging around, you don’t mind what you’re seeing.”

“I never it was a turn-off,” said Celestia. “I think I’m starting to understand what it feels like to need one’s balls emptied…”

“I know my way around a giant cock,” said Chrysalis, grazing her fingers across the skin of Celestia’s shaft. “If you’d take me on a date, Celly, I’d show that meaty monster a very good time.”

“You?” said Celestia, slapping Chrysalis’ hand away. “After spending five years away from Equestria, you think you’re the one I want to spend time with? The woman who infiltrated my castle, let an invasion of my city, and tried to strike me dead?”

That was precisely the reaction Chrysalis had expected; she’d only asked because she wanted an opportunity to antagonize her old nemesis. Still, Celestia’s tone had been a little hurtful. “Well, if you didn’t want to, all you had to say was-”

“I’d love to.”

“Uh… whuh?”

“Sounds like fun,” said Celestia, with a confident smile. “If you’re free in a couple hours, come by my room.” She turned her eyes back towards Twilight and Spike, whose intense lovemaking was reaching a fever pitch.

“Queen Mommy’s gonna cum,” grunted Twilight, ramming four feet of thick purple cock into Barb’s absurdly stretched pussy. She had Barb’s scaly purple butt clutched in both hands, and her colossal tits rested on the dragoness’ back, jiggling violently with each hammering thrust. “Do you want it, Barb darling? Do you want your mom’s big hot load?”

“Yes,” moaned Barb. “Please fill my pussy, Queen Mommy, make me big, fill me up with your cum…”

Twilight shuddered, hilting her cock in her dragon daughter’s cunt, and an audible liquid gush erupted from her cock. The first shot of cum was huge; Barb’s tummy instantly bloated so big that it lifted her hands and knees off the ground. The next burst inflated Barb’s wobbling belly even further, so big that Twilight had to stand up in order to keep her cock embedded in Barb’s pussy.

Luna and Celestia watched wide-eyed as Twilight and Barb rose higher atop Barb’s cum-filled tummy. Chrysalis and Umbra watched the spectacle with interest, but didn’t seem quite as impressed; no doubt they’d seen the same thing plenty of times.

“That is… quite an impressive load,” said Luna, caressing her inner thigh with the fingers of one hand. “Is that typical?”

“Yes, it’s always like this,” said Umbra. “A load this big doesn’t serve much of a practical purpose, but Queen Twilight enjoys being potent… and a long climax is her favorite way to unwind.” Stepping closer to Luna, Umbra laid a hand on the wide expanse of her huge blue buttocks. “How do you like to unwind, Luna? Perhaps I could show you a good time in the new Canterlot.”

“You saw Chrysalis asking my sister on a date, and you had to try your luck, eh?” said Luna. She shook her hips, making her bottom jiggle. “Sorry, but I would rather spend an evening with a manticore than with a tyrant. It’ll take far more than a pair of tits to convince me that you’re worth my time.”

“Come now, Luna,” said Umbra, grabbing a handful of jiggling blue butt-cheek. “You know better than anyone that dark hearts can be reformed. Just what are you afraid of, moon mare?”

“I am certainly not afraid of you,” spat Luna. “Reformed or not, you are Twilight’s lapdog now, Umbra.”

Umbra scowled. “I see how it is,” she said. “We are similar, aren’t we, Luna? Both exiled, displaced in time… I think you’re afraid that I’ve adjusted to this new world better than you have. What if Luna is still awkward and unloved, and Umbra is a cherished pillar of the community? Being seen in public with the long-absent moon princess might hurt my sterling image…”

“Do you honestly think the ponies of Canterlot-” Luna snorted indignantly. “Very well, the two of us shall step out together, and we shall see-”

“Great!” said Umbra, giving Luna a hearty slap on the behind. “I’ll come by your room later today, Luna. Wear something pretty.”

Luna was gasping - first, because having her bottom spanked was surprisingly pleasurable, and second because she realized she had just agreed to the date she had tried to turn down. “Umbra-” she sputtered.

“Don’t worry, it’ll be a good time,” said Umbra. “Now why don’t we all take a seat? Twilight enjoys being watched, and she won’t stop coming for quite a while.” Magic flared on her horn, manifesting three comfortable-looking chairs… and one wide couch. “For your incomparable rear, Luna darling,” said Umbra, gesturing towards the couch.

Each of them took a seat, watching Twilight bloat her number one assistant with gallons upon gallons of spunk. Barb’s belly was ten feet wide and still growing with each gush, rising towards the ceiling as Twilight’s bottomless balls fired off their immense supply of hot spunk. The other ponies chatted with each other, marveling at the endless orgasm. Celestia’s cock never went down; as she watched Twilight inflate Barb, her nine-foot boner fired off the occasional gallon or precum onto the throne room’s carpet.

It was almost a half hour before Twilight stopped coming, and by that time Barb’s cum-swollen tummy was taking up about half the throne room’s floor space. Sighing with satisfaction, Twilight dragged her cock out of Barb’s pussy and collapsed onto the dragon’s belly like it was a waterbed.

“Twilight, that was remarkable,” said Luna, standing from her couch. “Is that truly a typical sexual release for you?”

“Well… that was just round one,” said Twilight. She rolled over, displaying her slick - and still fully hard - cock. “It’s going to take a while before these nuts are properly drained. Chrysalis, Umbra, why don’t you take the two of them back to their rooms? It was nice having an audience, but I don’t want to hold you captive all day.” She walked across Barb’s belly, her feet sinking into the scaly blob with each step, until she arrived at the dragoness’ mouth. “Open wide,” said Twilight. “Queen Mommy has a meal of hot creamy cum for her good dragon girl…”

Barb opened her mouth as wide as she could - and then her jaw stretched much, much wider as Twilight shoved her cock down her throat. Celestia and Luna took one last moment to marvel at the sexual spectacle, then followed Chrysalis and Umbra out the door.
