“What?” Twilight gasped, eyes wide. “You can’t be serious. You want a… a what?”

“Did the Great and Powerful Trixie fucking stutter?” Trixie tossed off her wide-brimmed magician’s cap and let it fly into the crowd. “I want a Magic Duel!’”

“Now, hold on a minute,” Applejack said, shoving her way in between the two unicorns. Twilight took a step back, sighing in relief. Applejack probably wasn’t a serious match for a unicorn as powerful as Trixie, but it never hurt to have six feet of farm-mare muscle standing by her. Against Trixie’s five-foot-two frame, she looked positively imposing. “You got some nerve to come to our town demanding some kinda spell-slingin’ shoot-out with Twilight. What gives you the right?”

Trixie grinned. No verbal response, not even so much as a dismissive noise. Just an infuriatingly smug grin.

Applejack’s eyes narrowed dangerously. “Ain’t even gonna try and defend yourself? Or do y’all just wanna get your sorry ass thrown outta Ponyville?” She punctuated her threat with a good solid jab, square in the centre of Trixie’s chest from an angry index finger, sending the smaller mare stumbling backwards a few steps. Trixie grunted, letting out a muffled ‘oof’, but kept right on grinning.

There was a brief gleam of light from Trixie’s chest. Twilight frowned.

“Right, that’s it. Hup!” Applejack effortlessly hefted Trixie onto her shoulder in a fireman’s carry. “Y’all ain’t welcome here, least not if you’re gonna be stirring up trouble.”

There was another gleam. “Applejack, wait.”

She paused, holding the still-grinning Trixie over her shoulder. “What’s up, Twilight?”

Twilight’s frown deepened. “She’s got something there on her neck.” Not that she wouldn’t have been happy to see Trixie booted out of Ponyville, but something about this didn’t feel entirely right. “Trixie, what are you up to?”

“Why, nothing at all!” Trixie said, mock-scandalized at the accusation. She held up a silver amulet, studded with a single fire-red ruby. “This is just a simple gewgaw, a decoration for my stage outfit. All I want is a very fair, very square, Magic Duel!” She chuckled to herself, as if she’d just said something funny. “And I always get what I want. Now unhand me, ruffian.”

For a moment, Applejack didn’t seem sure what to do. She looked back to Twilight. “Uh…?”

Twilight shrugged. Well, if that was all Trixie wanted… And it wasn’t like she couldn’t magic herself out of Applejack’s grip any time she wanted to, anyway. “Okay, Applejack, you can put her down. No need to get physical.”

“Gotcha.” Applejack set Trixie down gingerly, coughing to herself. A hint of red spread across her cheeks. “Sorry to have, um, gotten so rough with ya. Got a mite carried away, is all.”

“No trouble whatsoever,” Trixie said, brushing the dust from her cloak. “You can make it up to me by stepping aside. Trixie has business to deal with.” Applejack grunted her disapproval, but reluctantly backed off. “Thank you, Jackanapple. Really, Sparkle, you should put more effort into training your pets.”

Twilight suppressed an indignant comeback. “What are the terms, Trixie?”

“The contest is a simple test of raw magical power and of endurance. We take turns casting spells on each other, back and forth. No other restrictions. You can use whatever means you deem necessary to win.” She bowed, a wild and exaggerated gesture. “I’m sure you can guess this, but first to cry uncle loses. That, or being completely incapacitated. Whichever comes first.”

Twilight scoffed. “No deal.” She crossed her arms. “I’m not going to agree to a duel with rules that encourage cheating. Especially against you, Trixie.”

Trixie clasped her chest with another exaggerated gesture. “Why, Twilight, I am shocked and offended that you would accuse me of resorting to underhanded tricks to claim my just victory. But very well, if it will put your mind at ease; I, The Great and Powerful Trixie, will limit myself solely to basic magic. No outside help, just me as I am.” She bowed, again, in the same manner as before. “You are still allowed to use whatever means you deem necessary to best me, but I am limited to normal spells and whatever magical power I can muster.”

Twilight remained hesitant. Trixie was clearly up to something. “Why? What exactly do you want out of this, Trixie?”

Trixie’s grin widened, turning from smug to sinister. “Simple, dear Twilight. The winner takes all the magic–”

“Of the loser?” Twilight recoiled. “You can’t be serious.”

“Oh? Is the great Twilight Sparkle afraid that she might lose this competition in spite of the massive handicap that Trixie has given herself? I seem to recall you thoroughly demonstrating how greatly you outclass me the last time we met.” It was her turn to scoff. “I wouldn’t have pegged a pony capable of effortlessly lifting an Ursa Minor and transporting it several miles out of town as such a coward.”

Twilight bit her lip, keenly aware of all her friends’ eyes on her. She was supposed to be Ponyville’s resident expert on magic. How embarrassing would it be for her – for the whole town’s – reputation if she backed down from a con artist like Trixie? Princess Celestia would be disappointed, beyond disappointed, to hear that her student was a coward.

And what were the odds she would lose, anyway? She didn’t want to brag, but she did know her way around a spellbook. Better, at least, than a unicorn who exercised her mouth more than she exercised her horn. The rules Trixie had set down seemed awfully, suspiciously favorable, but what kind of trick could she possibly pull with those handicaps? Twilight wracked her brain, trying to find a loophole in Trixie’s wording, but nothing came to mind. Maybe Trixie really was so arrogant that she thought she could win like that.

“Alright, Trixie,” she conceded. “I’ll accept, but I want to put one more condition on our Duel: If I win, you won’t show your ugly face around Ponyville ever again.”

“Well, that hardly seems fair,” Trixie said, sounding hardly bothered at all. “But if you insist. Let it never be said that Trixie isn’t as generous as she is Great and Powerful. In fact, I think I’ll allow you the first move.”

Yet another suspiciously generous move on Trixie’s part. Twilight looked her up and down, searching once more for the trick. Besides that gaudy new amulet – probably plastic – she looked the same arrogant blowhard as ever. Even for a stage performer, Trixie was pushing the limits on public decency. She had hardly more than a silver-purple bra on beneath that ridiculous sequined cape, complemented by what had to be a thong. Showing off her body like some two-bit harlot...

As if she had a body to show off in the first place! Trixie’s figure was nothing special. Almost waifish, really. Thin, nigh-bony hips and hardly any chest to speak of. If not for the cape, it would be obvious she was just barely filling out that eyesore she called an outfit. Twilight nodded knowingly. That’s all Trixie was, when you got down to it: a show-off. All flash and no substance.

Still, she didn’t want to be hasty. She’d start off with something small, to test the waters. Maybe Trixie had cast some sort of reflective spell on herself, or some other devious trap. Twilight was a prudent strategist, and the first and best move in any game was to collect more information. A simple force beam would do. She lit her horn and fired off a pencil-thin beam of magic, striking Trixie square in the gut.

“Arrghh!” Trixie screamed, stumbling backward a half-second later. The amulet on her neck seemed to glow as she did so, probably reflecting the light off the spell. “What pain! What agony! Trixie wonders whether she may ever recover!”

Twilight huffed, once again suppressing an indignant comeback. Whatever. At least now she knew that Trixie didn’t have any secret magical defenses. That was all the information she needed from her first turn. “Your move, Trixie.”

“Hmph, no sense of drama.” Trixie once again dusted her shoulders off lightly. “No flair. So dull, Sparkle. Here, let me show you how to put on a real show.” She threw her cape back, the garment fluttering dramatically in the wind, and her horn lit up with a pinkish aura. “Behold!” Her exclamation was punctuated by a series of bright, pyrotechnic flashes, culminating in an explosion of colorful smoke and a dramatic fanfare of trumpets from nowhere.

Trixie’s horn dimmed, and she closed her eyes. “Your move, Sparkle.”

“...What?”

“Well, I cast a spell, didn’t I? That was my turn.” She once again smirked smugly. “Consider it a prelude to the biggest show on earth. Your move, Sparkle.”

Twilight coughed, waving the smoke away as it dissipated. What kind of game did Trixie think she was playing here? How could she be so confident that she’d deliberately waste her first turn? A vague sense of unease settled over her as she met Trixie’s violet eyes. She looked so calm, so self-assured. What was she hiding...?

She shook her head. Didn’t matter. Trixie was still going to lose. She lit her horn again, readying something that would be sure to wipe the smirk off Trixie’s face. A simple force beam would be foal’s play compared to Starswirl’s Disruptive Pulse. “Let’s see how you like this!” The magic buzzed, concentrating in her horn before shooting out as a brilliant burst of energy. It lanced through the air at just below the speed of light, striking Trixie in the chest. Direct hit!

“Oh!” Trixie gasped, her knees buckling slightly beneath her. Her amulet entirely undamaged, despite taking a Disruptive Pulse head-on. In fact, it seemed to be glowing brighter than ever. “You know, I do think I felt that one,” she purred, slipping a hand beneath her overstressed bra, fingers caressing a dark blue nipple. “And it felt fucking good. Are you sure you aren’t trying to seduce me, Sparkle?”

“I… What?” Twilight could only stare as Trixie continued fondling herself. In broad daylight. For all to see. Suddenly her face felt hot, her own nipples hardening beneath her blouse. Goodness, had she thought Trixie was barely filling out that outfit before? It looked now like it could hardly contain her. Was she…? No! She shook her head. “Snap out of it!” It was just a natural biological reaction. Trixie was simply an attractive mare. Of course an exhibition like that would arouse something in her. Probably every stallion in the crowd was popping a boner just watching that. It didn’t mean anything. “M-make your move, already, Trixie!”

Trixie smirked sultrily, licking her lips and giving Twilight a smouldering look. “So impatient, Sparkle. Are you not enjoying my little show?” Her free hand gently rubbed her exposed navel in small circles, before descending to softly caress her inner thigh. “Mmmm, like I said earlier. No sense of drama. Don’t tell me you’re not enjoying this.” Her ministrations on her breast picked up in intensity, and her other hand wandered toward its real target. Fingers traced teasing paths around her swollen cunt, fat blue lips just barely concealed by the glorified dental floss of her thong. Twilight blushed, putting a concentrated effort into staring away. It was definitely several sizes too small for Trixie, strings digging so deep into her supple hips it couldn’t possibly be comfortable.

Trixie moaned, a soft ‘ah’ as her fingers firmly pushed against a dark, glistening spot on the front of her bottom. “Or perhaps you’re angry at Trixie for not inviting you to join in?” She removed her hand from below the belt, holding it out to Twilight. Her fingers shone in the light, dripping with sexual fluids. “Care for a taste, Sparkle?” Twilight’s face flushed, and she darted her head to the side. “I’ll take that as a no. Tch, a prude as well. You’re no fun, Twilight~”

“J-just make your move, Trixie!”

“There’s nothing in the rules that says I have to cast a spell every turn, Sparkle. I’m far more interested in finishing off my little bit of fun.”

“... So you’re forfeiting your turn?”

“To put it bluntly?” Trixie said, magically unclasping her cape. “Yes. Why don’t you take your turn and see if you can get me off before I do, since you’re clearly not taking this contest very seriously? If you were, you would have obliterated me by now.”

Twilight gritted her teeth, a vein pulsing in her temple. Just who did Trixie think she was? Even if she was ‘Great and Powerful,’ even if she had just taken Starswirl’s Disruptive Pulse and gotten off from it? It wasn’t that hot! “Okay, Trixie,” she grumbled. “Fine. You want to get serious? Let’s get serious.”

She closed her eyes, flipping mentally through a cavalcade of spells that could really ruin a pony’s day. She’d held back a little bit last round, just a little. She hadn’t wanted to kill Trixie at first, but now she was having second thoughts. Whether she’d done something to herself or she had some freakish masochistic streak, it was clear that normal spells wouldn’t cut it against Trixie. Instead she’d need to pull out something big. Something like… a Ray of Solar Annihilation! Princess Celestia had taught her that one personally.

Twilight grinned as she focused a tremendous amount of magic at the tip of her horn. The Ray of Solar Annihilation was a special kind of magic beam, designed to be channeled continuously for a solid minute. It was the only transmutation spell one hundred percent guaranteed to turn a target into a smoldering crater, and Trixie was about to regret forcing her to use it. “Say your prayers, Trixie.”

She shut her eyes as the beam reached critical magical mass, scorching the air around her and only gaining in strength as it flew toward its target. Twilight winced slightly as her horn buzzed with feedback, a sign that the Ray had found a victim. Beads of sweat formed on her forehead as she channeled the raw, unbridled magic needed to sustain such a monstrous spell. In only seconds it chewed through all she had to give it, and then some. She could almost feel parts of herself being used to power it, her body seeming less and less substantial, as though she was pouring her own essence into destroying Trixie. But it was a necessary sacrifice. The Ray of Solar Annihilation was the only spell she had that could possibly destroy a pony as devious, as cunning, as Great and Powerful as Trixie.

The spell shorted forty seconds later. Twilight fell to the ground panting, body drenched with sweat. A cloud of dust had settled over the air, obscuring whatever had to be left of Trixie. “That’s…” She gasped for air – even her lungs felt exhausted. “...That’s the end. It has to be.”

“Oh, dear, is it? I wouldn’t have guessed.”

Twilight’s breath caught in the back of her throat. She was imagining things. Clearly, after Trixie had somehow shrugged off the Disruptive Pulse, and after putting so much of herself into the Ray, she was hallucinating a worst case scenario.

“I’m beginning to think that taking your magic when this is all over won’t really be worth it. Not if that’s the most you can muster.”

That had to be it. Even if Trixie could legitimately shrug off a Disruptive Pulse, nothing could take a Ray of Solar Annihilation at point blank range and not be reduced to atoms, let alone come out alive.

There was a gleam of light from within the still impenetrably thick cloud, illuminating only the shadow of… something. It couldn’t have been Trixie. It was some nine, ten feet tall, and that was far too big to be Trixie. It was the wreckage of a house, or some kind of bear even. But it couldn’t have been Trixie. Trixie was many things. Powerful, beautiful, magnificent, but she was certainly not ten feet tall, last Twilight had checked. “Come on, Sparkle. Get up. It’s far too early for this to end. I’ve hardly even doubled in size, yet.”

The shadow moved. Slowly, deliberately, it got closer and closer and closer, until it emerged from the dust.

Twilight’s jaw dropped.

The first thing to jump out at her, somewhat understandably, was that Trixie was, in fact, ten feet tall. Possibly more. She towered over Twilight. Even as Twilight slowly brought herself back to her hooves, she barely came up to Trixie’s navel. The next thing she noticed was that what little clothing Trixie had been wearing was completely gone. Well, mostly - somehow, that gaudy trinket had survived intact. Twilight couldn’t quite figure out from her angle of view exactly how it was staying on, but it was definitely there. Everything else was gone with no more than a few tattered shreds dangling off of her – though whether incinerated by the ray or shredded by Trixie’s swelling figure, there was no way to tell. Her breasts were bigger, too. Proportionally speaking, they had gone up a few sizes. They had been large before, but now they were each around the size of her head, and cast the shadow to match.

“Well, I suppose it can’t be helped,” Trixie rumbled, her face barely visible over the shelf of her expansive rack. Her tits wobbled as she laughed, bouncing and jiggling like the world’s biggest water balloons. “I’ll just have to use my turn teaching you the proper way to end a show. You see, Sparkle, you can’t have an ending...” A force pushed down on Twilight’s head like an invisible hand, her knees bowed ever so slightly until she stood face-to-cunt with Trixie’s crotch. “...without a climax.”

Twilight squeaked, struggling weakly to push her head back, but she was much too exhausted and Trixie’s magic was much too powerful for her to fight. She gagged, lungs desperate for a breath that wasn’t hot and humid, or reeking of Trixie’s arousal. Cerulean blue lips, swollen with need, undulated wetly, waiting almost expectantly for Twilight’s tongue. “T-Trixie,” she stammered as her breathing slowed, her body acclimating to the atmosphere of a massive, horny showmare.

“Trixie…” Oh, Celestia, she was so big now. So sensual, so overpowering. It was almost primal, in a way. The law of the jungle. If an animal as huge and desirable as Trixie wanted something, didn’t she deserve it? Wasn’t it her right, as the obvious alpha mare, to be served and serviced by those beneath her…? She bit her lip, sucking in a line of drool. Wait, what was she thinking? Trixie was the enemy! Some no-talent hack whose only goal in life was soaking up attention. How could she ever be desirable to anyone? “Y-you can’t be serious!”

“Very serious.” Twilight couldn’t actually see Trixie’s stunning face, but she could certainly imagine the grin on it. And she could definitely smell how much Trixie was enjoying this. “I think we both know who the winner of this Magic Duel is going to be, Sparkle. You’re always going on about helping other ponies. Why not help Trixie savor her victory lap?”

Twilight’s mind raced wildly. She wanted this. And she knew that she shouldn’t be wanting this, but that didn’t stop her from wanting it anyway - wanting it more. Why was she struggling? Why wasn’t she struggling more? Her mind was pulled in two different directions, both by her desire to have Trixie and by her rational thoughts loudly telling her that this was wrong.

What ultimately tipped the scales, though, was the lingering thought of the consequences of failure; at first she hadn’t put much stock in it, but seeing what Trixie had become brought back memories of the rules Trixie had laid out; the loser would forfeit her magical power forever.

“You – you used a spell! That means it’s my turn!”

The pressure holding Twilight in place vanished, causing her to fall backwards. Trixie grinned. “And here I thought you were just going to roll over and give up, Sparkle. Maybe this will be interesting after all.” She pushed her already oversized chest outward, a fat, pillowy tit cupped in each palm, practically inviting Twilight to aim a spell downlane. “You’re right. It’s your turn. Go on, Twilight Sparkle. Hit me with your best shot.”

And there was the problem. Twilight had already hit Trixie with her best shot, and it had done nothing. If anything, it had done less than nothing; it had left Trixie stronger and bigger and sexier than before. She had no ideas left beyond stalling for time, and she could only do that for so long.

“Foul! I call foul!” It was Rainbow Dash in the sky, her shouting breaking Twilight out of her lustful funk. “You totally cheated!”

“Cheated!” Trixie laughed. “Why, I’ve never seen such a vindictive audience! It seems Trixie can hardly breathe without being accused of cheating somehow.” Her horn glowed, magic wrapping around Dash’s wings and dragging her down to eye-level. At Trixie’s height, it wasn’t that long a way down. “Tell me, then: how have I cheated?”

“Ain’t it obvious?” Rainbow Dash snarled, seemingly unintimidated by the ten foot tall unicorn. “You’ve been casting some kind of growy spell on yourself every time Twilight takes a turn! I’m no expert, but there’s no way in Tartarus that’s any kind of ‘normal magic.’”

“Well, it’s clear you’re no expert,” Trixie said, releasing Dash’s wings. “A simple scanning spell would show that Trixie has cast nothing but the most basic magic, and only on her turn.” She grinned, shooting Dash a sly wink. “If you really must know why I’m so big, though, why don’t you ask your friend? It was her spells that made Trixie grow so big and…” A moan as she tweaked an engorged nipple. “...voluptuous.”

“What?” Twilight gasped. “I… but… but…” She was so confused and exhausted now that she could hardly put together a proper retort. It couldn’t be true. This whole time she’d cast nothing but spells meant to put Trixie in her place. Her proper place, as the biggest, most beautiful mare in… Her eyes widened as she caught herself. Could it be true? Could she have somehow, subconsciously, cast spells not to harm Trixie, but to empower her? How else could she explain her sudden, overpowering infatuation? That secret desire to give in and submit? Maybe, just maybe, she really had wanted this.

“Mmm…” Trixie groaned, hands increasingly busy exploring her massive form. “Well, it hardly matters to me if Sparkle wants to improve upon perfection, but it doesn’t look like she’s in any shape to take her turn this round.” Her horn flashed. Dash vanished into thin air, reappearing a second later between Twilight and the amazonian Trixie. “You talk awful big, for a talentless little pegasus, so why don’t you take Sparkle’s turn for her? The rules do allow her to use any means necessary.”

“Oh, what’s that? You wanna lose?” Rainbow Dash grinned, and Twilight groaned internally. If she didn’t know Dash quite as well as she did, she would be begging her to stop - Trixie clearly wanted this. There was something wrong, even if she couldn’t put her finger on it, but regardless of it was, playing along with the duel clearly wasn’t working.

But she knew Dash plenty well. Well enough to know that there was no chance that anything she could say would deter her friend from making a stupid decision. Still, she tried, her throat barely managing to rasp out a weak “Rainbow, no…”

“Alright, you asked for it.” In a rainbow blur, Dash zipped through the sky, gathering clouds together into a singly fluffy mass. As she stuffed more and more clouds into the pile, the whole mass darkened until it was nearly black, sparking ominously with electricity. “One big-ass lightning bolt to the face, coming right up!”

“Bring it on, shrimp.” Dash’s fur bristled at Trixie’s taunt, and Twilight suppressed a groan. “Maybe The Great and Powerful Trixie will actually notice your efforts.”

Dash shook with barely contained rage. “Fine! I wasn’t gonna do it, but if you want to eat a zapping, I’ll deliver.” She zoomed upward until she was barely visible against the clear blue sky. “Your order in thirty milliseconds or less!”

A blink of the eye later, she’d slammed into the stormcloud, and everything burst into light and sound. A thunderclap shook the whole town as the lightning bolt struck Trixie, blindingly bright. A direct hit. Twilight winced, not daring to look. A direct hit. Oh no.

And there Trixie stood, at the center of a ring of ash, a grin slowly spreading across her face. “Ooh,” she moaned, licking her lips in anticipation. “That was good.” This time, Trixie surged, one hand clutching a blossoming tit, the other sinking knuckles-deep into her soaking netherlips. Far from humbling her, Dash’s lightning bolt had only further provoked Trixie’s growth, stacking inch after inch of beautiful blue unicorn onto her already imposing figure.

“Mmm…” Trixie’s fingers quickened as her growth slowed, her gleaming-wet pussy dripping like a leaky faucet. She switched hands, savoring her own taste with a slow lick across her fingers. “My compliments to the chef,” she purred. Trixie turned her eyes upward, to where Rainbow Dash was watching transfixed. “Well? Get Trixie another!”

Dash’s face lit up red. “What? B-but… But I…”

“Another!” Trixie rumbled, horn aglow. The magic forced Dash into an about-face, giving her a light pat on the rump to speed her along. “And that’s an order, pet.”

“Y-yes, ma’am!” Dash squeaked, giving a shaky salute. “W-whatever you say, ma’am!” Her wings snapped to their full length, rigid and quivering. An innate respect for authority, twisted into obedience before an utterly dominant Trixie. She took off in a flash. “You want another, you’ll get another.”

“What on earth is goin’ on in that mare’s head?” Applejack said, half to herself. She scratched her head, bewildered. “This ain’t like her.”

“I don’t know, darling,” Rarity said, rolling her eyes in an exaggerated motion. “Hers is the hardest head in Ponyville. I can see her reacting to a plan failing by trying the same thing again only bigger.”

“Only bigger,” Applejack murmured, licking her lips. “Wouldn’t want that to happen now, would we?”

“No,” Rarity replied, her dainty hand trailing down her midriff to the hem of her skirt. “We certainly wouldn’t.”

Rainbow Dash was a blur, canvassing the sky above Ponyville in a wild, seemingly random fashion. Every cloud in the sky, she gathered into the town square. And then, when that proved inadequate, she expanded her search to include the sky above the Everfree. The clouds there were bigger, dark and angry and wild, black as night and heavy with rain, and - more importantly - with lightning.

But it still wasn’t enough. The rainbow blur darted into the weather patrol’s offices and emerged lugging an absolutely massive box. “What we have here,” she said, voice straining with effort, “is Ponyville’s cloud supply for the next three months.” She dropped the crate, a resounding THUMP echoing through the town square. Rainbow Dash lifted off again, hovering over the cloud crate. A crazed grin was plastered on her flushed face, and one of her hands was inside her shorts, massaging a conspicuous dark spot. “You want more? How’s this for more?”

With that, she kicked the box, hard, and the top burst off, unleashing a seemingly endless torrent of cloudmass. Dash blurred again into a colorful streak, funnelling the clouds into the center of the square. The air crackled with static as ever more energy condensed itself into Dash’s supercloud. The gathered ponies squirmed uncomfortably, all of them wary of the building storm overhead – except one. Trixie stood alone just beneath it, her arms outstretched, inching bigger just by feeding off the ambient power. Her face was frozen in pure bliss, thick blue nipples standing longer than Twilight’s thumb and hard enough to cut diamond. Her low, rumbling moans reverberated throughout the whole town, and even with all that power, her eyes were locked expectantly on the cloud, eagerly awaiting her next growth spurt. Twilight had already made her the greatest, most powerful pony in Ponyville. Now all she needed was Rainbow Dash to crown her as a proper goddess.

Twilight took a step backwards. “Oh. Um. Oh dear,” she muttered. Looking around, everypony’s eyes were glazed over, staring mindlessly at Trixie. Fluttershy fidgeted, her face flushed bright red and her tongue lolling out lazily. Applejack had one hand shoved under her dirty white tank top, and the other into her jeans. Rarity stood, arms rigidly by her sides, her horn glowing dark blue, pulsing in time with sensual moans. “This is, uh...”

“Wheee!” Pinkie Pie tore off her blouse and skirt with one swift motion, leaving her completely nude. “C’mon, Dashie, hurry up!”

Twilight stopped, turned, and ran. She ran as fast as her legs would take her, fighting her body’s every impulse to stay and watch Trixie become truly all-powerful. A voice in her head, mad with lust, screamed at her to turn around, to pour even more of her magic into Trixie. Her new duty in life was to fuel the Great and Powerful Trixie’s next mind-blowing orgasm, feeding her mistress more and more and more and more and- Twilight shook her head in a vain attempt to clear the lustful fog that enveloped it, and continued running. Her basic, most primal instinct to survive was shouting to get as far away from Trixie as she could. And even further than that, if possible.

She’d made it all the way to the outskirts of Ponyville when the mother of all thunderclaps burst in town center. Windows shattered, the ground shook, and even as far away as she was Twilight felt rattled to her core. Then followed Trixie’s screams of pleasure, almost as loud and growing even louder. It wasn’t long before Twilight could see Trixie’s silvery mane peeking over the rooftops, followed by her gorgeous, goddesslike face. Even in orgasm she looked positively radiant, hands pawing madly at tits approaching house-size, desperate to squeeze every last drop of satisfaction from her climax. “More!” she shouted, and then again, louder; “MORE!”

“There, uh, isn’t any more, ma’am.” Rainbow Dash sheepishly scratched the back of her head, perched atop a roof to speak with her new mistress face-to-face. “That was every cloud in the greater Ponyville area. I’d have to go all the way to Hoofington at the closest to get more. And that’d take too lo- lo- looooooooong,” Rainbow Dash’s speech trailed off into a lewd moan as she fell forward onto her knees, and then backwards onto her ass, legs spread wide and hands furiously working her dripping pussy.

“Mmm, so what you’re saying is that you’re ending your turn?” Trixie purred. Dash didn’t respond, her mind lost to lust as she relentlessly fingered herself. “Gooooooood. I’ve got all this new power to play with,” she cooed, gently rubbing the amulet. It had grown with her, and was now embedded into her flesh, nestled right above her titanic cleavage. “And where’s the fun in not giving it a test run? Mmmm, watch in awe, Ponyville. It’s time for the Great and Divine Trixie to really show off.”

Her horn ignited, enveloping her body in a dark red aura. Her hands caressed her body, starting with the swell of her stupendous rack, lingering on her powerful abdomen, and finally settling at the plump mound of flesh just above her cunt. And they brought the aura with it, condensing and intensifying the glow until it was an almost blinding light centred right where her hands were massaging. “Mnggggg, that feels good, but it’s not enough. A disappointing use of a turn, for now.” She sighed, a grin forming on her lips. “But how shall Twilight Sparkle spend hers? It doesn’t seem that she’s here right now, so I suppose it falls to me to choose a volunteer in her absence. You.” She pointed into the crowd, the amassed ponies parting to reveal a terrified Fluttershy. “Here. Now,” she commanded, pointing at the glow.

“Oh. Um, yes, m-mistress Trixie. R-right away.” She nervously took off, hovering her way to her goddess’s crotch. “Um, what do you-”

“Clothes off.”

“Oh,” Fluttershy breathed. “Yes, Mistress.” She reached down to the hem of her sweater, pulling it up and over her head to unleash her own sizable tits. Next was her skirt, eased carefully off her flaring hips, followed by her stained panties. Her face burned with embarrassment as she hovered in the air, nude in front of every pony in Ponyville. Oh, yes, it was shameful to show off her big, naked body, but it was wonderful at the same time. She’d never really believed those ponies who’d said she had the best figure in Ponyville, and now standing next to her goddess, they could finally see just how much bigger, more luscious, Trixie really was. And she, of all the ponies who could have been chosen, had been called on to service Trixie. The thought of that alone made her positively gush, robbing her of her breath. “What an honor.”

Trixie stared approvingly, licking her lips as her vision bored into Fluttershy. “Yes, you’ll do. Now,” she pointed at the glow. “Pleasure me. Now.”

Fluttershy trembled with anticipation as she flitted closer toward Trixie’s pulsating folds, the hot, humid atmosphere of her mistress’ arousal filling her lungs, shoving every other thought out of her head. She resisted the urge to moan, to give into simple primal lust and pleasure herself to Trixie’s overwhelming presence. Her goddess had given her a job, and her sole obligation was to complete it. Pleasure for herself was nice, but pleasure for Trixie was heaven itself. She took gentle landing on Trixie’s glowing mound, giggling to herself as the magic ran through her like its own gentle massage. How wonderful! And this was only the barest hint of Trixie’s power. Her eyes widened as her mind raced with possibilities, dreaming of all the things her goddess could do now.

“You don’t have to wonder, pet,” Trixie purred above her. “Here, have a taste.”

Fluttershy groaned as the magic raced up to her breasts, engulfing her sizeable rack in Trixie’s scarlet aura. Meanwhile, something thrummed up from the warm blue flesh beneath her hooves. Tremors hinting at what was to come. She groaned as her chest ballooned outward. Tits that had always put her friends to silent, seething shame doubled in size, then doubled again, just in time to meet the leviathan cock rising between Trixie’s legs. It throbbed powerfully between her tits, sending all kinds of good vibrations through her ever-so-sensitive mounds. And at the base of her jiggling, bean-bag-sized breasts, she could feel Trixie’s heavy balls pushing her upward, gurgling and churning as they filled with a lake’s worth of thick seed.

“Mmm, oh,” Trixie moaned, tracing a finger proudly around the flared head of her new equipment. Droplets of musky precum, the size of Fluttershy herself, were already running down her shaft, baptizing her pet in the warmest and stickiest way possible. “Very good. But still not enough.” She pointed absently to a few earth ponies in the crowd. The farmer pony Applejack, and a few of her inbred cousins no doubt. “You, you, and you,” she murmured, even her faintest whisper loud and clear to the tiny ponies below. “Assist her.”

She groaned again as a trio of ponies attended to her burgeoning balls, kneading, sloshing, and worshipping them as if they were all that mattered in life. “Not bad,” she sighed, her amulet aglow as the earth ponies’ strength flowed into her, pumping her with still more size, even more divine appeal. It was a wonder that they weren’t creaming themselves at the mere sight of her, but just a little more magic, and they would be. “Keep at it.”

Her baser needs seen to by her loving servants, Trixie had time to let her attentions wander. Oh, this was her town now! More and more hers with every shove and caress from her earth pony attendants. A warm glob of pre welled from her newly-grown cock as she imagined herself even bigger, looming over Canterlot itself. A true goddess to reign over all Equestria. Backwater hicks made acceptable pets, but oh how much sweeter it would be when Celestia herself was a slave to her desires, barely even the size of her own nipple.

And speaking of Celestia, where was that student of hers? Twilight Sparkle seemed to have scampered off somewhere, like a mouse afraid of the big, bad pussycat. It didn’t matter to her at this point - she’d more than assured herself victory in their little magic duel - but she wanted to rub it in more. She wanted to see Twilight, once so high and mighty, falling over herself to surrender and worship her. Gushing with praise for the Great and Divine Trixie… not to mention something a little stickier.

“How shall I find her, though?” Trixie mused, reclining back into a little house. “A searching spell? No, too easy. A challenge? Not again.” A shudder ran through her body as her swelling balls overtook her tiny servants, all the earth ponies’ strength only barely enough to hold up her titanic sacks of seed. “Oh, of course,” she chuckled, beckoning to some more ponies to help - and contribute their magic to her in the process. All she had to do was wait and grow, and soon enough there would be no place in Equestria for Twilight to hide.
