Trixie lounged. A smaller, more insignificant pony might have said that she loomed, her immense form dwarfing Ponyville’s tallest structure, straining even the limits of the mountain she was reclining on… but in the eyes of Great and Divine Trixie, she simply lounged. She stretched languidly, yawning. “Mmmm, becoming a Goddess is surprisingly tiring work. But it’s my turn, and I choose to use my turn to take...” another yawn, “...a nice little break. Mmm, yes, a little lower.”

“Yes, mistress,” came a chorus of voices from between her legs. A half-dozen pegasi – no other ponies could reach at that point – shifted down a few more feet, licking and stroking just beneath the shelf of her medial ring. Below them, a crowd of earth ponies, busy with the full-time task of massaging her house-sized balls. Ample streams of thick Trixie juices rolled in from above, supplemented by Fluttershy’s leaking milk factories. The goddess had long since outgrown the need for her pet’s tits, but she still enjoyed the soft, pleasing warmth they provided.

“Aaaah…” The mountain rumbled worriedly beneath her as the unicorns blasted her with another shot of magic. The amulet, nestled cozily between her truly massive breasts, glowed softly as it converted everything into even more size, still more magic for Trixie’s vast reserves. “A good use of a turn, Twilight,” she chuckled as Ponyville shrank ever smaller beneath her gaze. Soon enough, she realized, she’d be able to straddle the whole village. The thought turned her on almost as much as the whole village’s efforts to please her, a shiver of excitement running through her spine. “Keep it up, and you may beat me yet.”

She did wonder idly where Twilight had gone, exactly. Spending a turn on a simple scanning spell would have confirmed it easily, but she almost preferred the mystique of it. Imagining Twilight fleeing worriedly to the ends of Equestria, doubtlessly aware that soon Trixie would be bigger than Equestria, and far more beautiful, too. Perhaps Twilight had already given into her lusts, moaning Trixie’s name as her mind filled with fantasies of her greater, more powerful nemesis. That would be delicious. She bit her lip, worshippers shouting in surprise as fresh rivers of precum ran down her shaft. The temptation to go find her, to lord her new size and power over an antlike Twilight, was powerful. But she resisted. It would be all the sweeter when Twilight returned willingly, begging to feed her, desperate for the opportunity to further her goddess’ pleasure.

And anyway, it was her turn. “I suppose I could just forfeit again, but where’s the fun in that, now? Hm, but if I don’t want to forfeit, and I don’t want to find Twilight, whatever shall I do?” She placed a finger to her lips in an exaggerated motion. “How about you, pets? Do any of you have any ideas?” The only response was a faint moaning from the enormous mass of titflesh that Fluttershy had become. “An excellent suggestion, Slutterby! Giving Twilight’s friends a taste of my new power would be deliciously personal. But who to start with? I’ve already made you my Royal Titfucker. Perhaps I should reward the Rainbow one for that storm earlier. It was, mmm, quite delicious.” She licked her lips. “And she should be punished for her failure to create an even bigger storm.” She snapped her fingers, the booming sound echoing for miles. “You heard me, pet! To me, now!”

After a few moments, Rainbow Dash erratically fluttered her way to her mistress’ face. Her wings were rigid, shaking slightly with arousal, along with the rest of her body. Every other pony in town was also deeply under Trixie’s spell, but stubborn, single-minded Dash had it worst of all. The definition of everything awesome in her mind had been hardwired straight to her mountain-sized mistress, and even the slightest hint of praise from Trixie’s lips was good now for another orgasm. “Y-yes, ma’am?” she breathed shakily, soaked in everything from sweat to her own juices. “You called?”

“What do you think, pet?” Trixie purred. “Should I reward you? Or punish you?”

Rainbow Dash groaned in response, eyes rolling into the back of her head as she came just from the sound of Trixie’s voice. She gurgled slightly, tongue lolling out of her mouth as she twitched. “Ghaaaaaa fuuuuuuck yesssssssss~”

Trixie sighed. “That wasn’t a yes or no question, pet. I suppose that means you want me to punish you, hm? Willfully disobeying your mistress in order to provoke me? Is that it, pet?”

“Ye-hesssss! Punish me! Reward me! Change me! Make me huge or give me a cock or huge tits like Fluttershy or turn me into an enormous fucking dildo and use me to pleasure yourself! Turn me into a dog so I can be your bitch in heat! Fill me so full of your cum that I fuckin’ pop! Use me! Abuse me! I don’t care! I’m your fucking plaything!”

“Well!” Trixie’s horn glowed a scarlet red, a grin spreading across her face. “Since you asked so politely, pet, I suppose I do have a few gifts I can bestow upon you…” The magic concentrated at the tip of her finger, more than enough to suffuse Dash’s whole body with her divine power. The finger advanced slowly toward her, Dash’s eyes following it like a dog’s would a steak. Oh, yes, she wanted this. Twilight was a nice friend and everything, but only Trixie could give her the stuff of her fantasies.

“Not so fast, Trixie!” At first Trixie didn’t seem to have heard, so huge that a single pony’s voice down near her hooves could barely reach her ears. Then she yelped as a ray of purple magic shot up into her chest, the force of it almost enough to jiggle her tits. It didn’t hurt at all, of course, but it was strong magic. Easily enough to send her a dozen feet up. “Oh, yes,” she groaned, the spell fizzling at her fingertips. “Who was that? Step forward, pet. Trixie wants to reward that one.”

Her eyes glanced off a disappointed Rainbow Dash, down to the crowd fervently worshipping her. There, standing just slightly apart from her devoted pets, was a rather defiant-looking Twilight Sparkle. “Aha!” Trixie laughed. “Twilight! How good of you to come back and finish our duel. The Great and Divine Trixie had almost thought you were afraid of her great magical prowess, or perhaps too awed by her radiant beauty to show your plain face. Are you ready to surrender, then?”

“Not just yet.”

Twilight’s face wore an oddly disconcerting smile. Something about it made Trixie pause. At her size now, Twilight should have been falling over herself to give up. A glint of lust still shone in her eyes, true, but… not for her. Absently she rubbed the Alicorn Amulet, as if checking to make sure it was still there. Whatever Twilight was doing now, it didn’t make sense.

Still, no matter. Twilight was a flea now. Less than a flea to her. In fact, it was better this way. Twilight could remain defiant to the very end, her confidence draining with every new spell she fed Trixie. Perhaps she was even going to try using the Elements of Harmony! The most powerful source of magic in all Equestria. Trixie nearly came just thinking that. If she was merely big now, a blast from the Elements was bound to make her titanic!

“From what I can tell,” Twilight said, “it’s my turn now. But before I take it, I just want to ask you a single question, Trixie.”

“Oh?” Trixie cocked her head. It didn’t matter what Twilight asked. Even if she already suspected something about the Amulet’s powers, it wouldn’t help her now. “And what’s that, Sparkle?”

“What would I call my father’s brother?”

“Your father’s… brother?” Trixie had to stifle a laugh – best not to deafen the little pets. Still, what a stupid question! Twilight could have asked her anything, anything at all, and she chose this joke? No wonder she was back for another round! Only an idiot would even think of asking something like that. “Well, I’d think even you could guess that one, Sparkle,” Trixie said confidently. “Uncle!”

Twilight’s grin was wide enough to split her face. “Yes, Trixie,” she said, nodding. “That’s exactly right.”

Too late Trixie realized what had happened. Her eyes widened, a window-shattering squeal escaped her throat. The Alicorn Amulet felt searingly hot against her skin, glowing ever brighter as it concentrated all her stolen magic within itself. “Loser is the first to cry uncle!” she gasped. “No, stop! I’ve been tricked!”

But there was no stopping the Amulet now. In a blinding flash of light, visible for miles around, the Alicorn Amulet shot out a rainbow beam. A blast of magic containing nearly all the magic Ponyville had to offer; its target: Twilight Sparkle.

It felt good. REALLY good. Like she was being filled with… something. Something warm and soft and big. So very big. So very full. Bigger and fuller and bigger and fuller and bigger and fuller and BIGGER and FULLER and – Twilight gasped as her sensible white blouse was the first part of her outfit to go, the fabric shredding against a wave of purple titflesh. Her breasts were, after all, much larger than Trixie’s had been before she started growing, so it only made sense that she would reach that point sooner. Trixie stammered incoherent excuses, begging no one in particular to please, please, just let her win. She was supposed to win, dammit! Twilight tuned her out, focusing instead on the pleasure of her own growth. She grunted as she felt her panties snap, and then her pants following suit, unable to contain her massive form. Massive and growing. She only dimly registered the actual process, too lost in the sensation of it, the raw pleasure of growing bigger and bigger and bigger.

She was vaguely aware of Trixie, slowly returning to her normal size slightly faster than Twilight was growing. Of her friends, now free from Trixie’s mental manipulations. Of a very flustered Fluttershy. And a somehow even more flustered Rainbow Dash – “Okay, no one heard that stuff I said to Trixie, right? About being a bitch in heat and stuff? Right? Because I didn’t actually say anything about being a bitch in heat to Trixie and anyone who says otherwise is fucking lying to you.” Applejack was standing at Trixie’s hooves, a furiously blushing Rarity right beside her, the two ponies hurling very loud and angry words of general abuse at the shrinking unicorn’s diminishing ballsack. And Pinkie Pie was-

“Hey, Twilight! I’m just gonna ride your shoulder while you get bigger, ‘kay? Awesome!”

Pinkie Pie was being Pinkie Pie. Twilight ignored her (she was somewhat used to that at this point) and basked in the warm feeling of all of Trixie’s magic flowing into her. Suffusing her being. It felt… nice, really. Like a full-body massage, her nipples hardening deliciously as her sensitive breasts blew up bigger, fuller. A hand wandered down to her fat, dark purple lips, finally ready to satisfy her own burning arousal. Sure, she was putting on a show for the whole town, but she needed this. Having resisted the lust-inducing effects of Trixie’s magic for so long, she deserved it. And with her body rapidly approaching the size of Ponyville itself, nobody was going to argue that.

Twilight groaned as she finally reached Trixie’s old height, sitting just a little taller than a mountain… and kept growing. Just as Trixie’s magic seemed to have gone dry, a thousand smaller pools opened up to her, fueling her growth even further. “Huh?” she looked around. “Shouldn’t… shouldn’t I have stopped?”

“Why would you, silly?” Pinkie Pie laughed in her ear. “Don’t you remember the rules?”

“Um…” She tried to recall the exact terms of the Magic Duel. All the costs of losing, and the prizes for winning. “Winner takes all the magic,” she said, smiling serenely. At the time she’d thought that meant taking only Trixie’s magic, but with the Alicorn Amulet enforcing the rules precisely, it really did mean all the magic. All the magic in Ponyville? All the magic in Equestria? In the world? She didn’t know, but she wasn’t about to complain. It was hers now. All hers.

“Ah!” She gasped as the second wave kicked in properly, big enough now to totally encircle Ponyville with her legs. Her fingers worked faster and faster, the merest dribblings of her arousal easily enough to fill bathtubs to the tiny ponies down below. And still she grew. All eyes were on her now, every pony giving her the same adoring, lustful looks they’d given Trixie. The same worshipful gaze Trixie was giving her now. Along with the magic, she must have taken whatever power Trixie had held over other ponies, only she was that much bigger, and therefore it was that much stronger.

The realization dawned slowly in her eyes: now she was a goddess… and not some paltry, play-divine figure like Trixie. No, with all the magic at her fingertips now, reality itself would soon be her own personal bitch.

“Ooooh, Twilight…” Pinkie moaned, still perched on her shoulder, hands madly groping her bubblegum pink breasts. “You’re so… huge! And so hot!”

She wasn’t about to argue with that, nor with the ponies trying to pleasure her any way they could. Earth ponies and unicorns scaled the immense wall of her thighs, licking and humping all the Twilight they could. Pegasi buzzed around her like a swarm of flies, doing all they could to further her arousal. She giggled as she thought she saw Rainbow Dash hugging the erect nub of her nipple, a pleasant tingle running through her chest. It was so little, so inconsequential to her, but from any normal pony’s perspective, there was easily more nipple than there was Rainbow Dash. And that was fantastically hot.

Twilight pulled herself slowly to a standing position, awed by just how tiny everything was beneath her. Ponyville was only barely too big for her to cross in a single step, and a second later not even that big, as she shot higher and higher into the air. She looked slyly back toward the mountain Trixie had once used as a backrest. Almost as big as she’d been before the second growth spurt, and now… “I hope nobody minds if I just put this to a better use,” she said chuckling, big enough to place a hoof on both sides of the mountain. “I mean, I did save the town.”

Size was rapidly becoming less of a problem as Twilight eased herself down on the mountain, gushing enough to coat the summit in her copious juices. Lips parted easily as the top slid inside, a cornucopia of textures assaulting her senses, her cunt convulsing around the solid stone peak. She squealed gleefully as she pulled back up, waiting to grow even bigger, then dropped back down, claiming still more of the mountain as her own. None of what she was feeling physically could match the pure ecstasy that came with knowing she could fuck a whole mountain. More than fuck a mountain, she realized as she thrust further and further down, taking more and more and more into herself. It was like a race to see which would come first; the point where the mountain was no longer big enough to satisfy her, or her orgasm.

“Bigger…” she muttered through the haze of arousal. The tip of the mountain had become the top quarter, and was quickly approaching an entire third. “Bigger,” she grunted as she took fully half of the mountain into herself. But it still wasn’t enough. “Bigger!” She slammed her hips down, the force of her thrusting comparable to an earthquake. Now that she was big enough to take an entire mountain to the hilt, she came to the realization that the position she was doing so from was somewhat awkward, so as she lifted herself up, she reached down and casually snapped it off of the ground at the base, like a twig, before flopping onto her back to more efficiently thrust it into her body. “Bigger!” But it was only a few moments before it was too small for her to properly use. Only four more good thrusts and it slipped from her fingers, lost to the moist depths of her sex. She frowned slightly, before a mischievous grin slowly spread across her face. Here she was, with all this brand new magic to play with, with more and more and more suffusing her very being every second. Why was she disappointed that the mountain she was using as a dildo had been eaten by her vagina? She was Twilight Sparkle, dammit, surely she was more creative than that.

And besides, she was a fucking goddess. Her horn was enveloped in a blinding aura, a multitude of swirling colors, the colors of all of the magic in Ponyville and more, soon to be all of the magic in Equestria, and then beyond even that. “BigerrrrRRRRRRRR!” she screamed as the aura enveloped her whole body, and she began to change. Muscles rippled and tensed beneath her skin as soft, bookwormy fat melting into a properly divine figure. She idly flexed an arm, revealing a bicep that made even the tallest mountain look like a pathetic anthill. She cried out in a mixture of ecstasy and agony as wings erupted from her back, her new wingspan putting entire continents to shame. After all, if she was going to be a goddess, why not look the part?

Twilight sighed as the last pools of magic in Equestria finally ran dry, her growth topping out at just over double the size of Equestria itself. It would do for now, she supposed. There was still more magic to be had, still plenty of fuel to power even more growth… but she could leave it for now. It was all hers by right, and she could claim it whenever she wished. For now, she had more pressing concerns. Namely, her need to finally get off.

“Thanks for the idea, Trixie,” Twilight rumbled, groaning as eyes glowed with a pure white light. Mile upon mile of dark cockflesh spilled from between her legs, fed by a pair of hefty, purple-furred balls. She bit her lip, recalling her fantasies from just hours before, when she’d been under Trixie’s spell. How she’d nearly orgasmed to the idea of Trixie’s cock utterly dwarfing the Two Sisters’ Castle. Goodness, how things had changed. Had Trixie been even twice that big, she’d still have been overshadowed by her own throbbing stallionhood. No, not even that. Trixie would hardly have been the size of one of her own fuzzy testicles, churning and sloshing with a literal ocean of cum.

There was hardly anything large enough for her to fuck properly, but at her size she supposed it hardly mattered. The planet itself qualified as a plaything to her now, its lesser inhabitants – members of the cult of Twilight, she supposed – easily protected with only a fraction of her tremendous magical power. Twilight let herself fall to the ground, the earth cracking and crumbling with the impact of her impossible weight. She giggled as warm, gooey magma surged up to cradle her. To any other pony, deadly hot, but to the planet’s goddess, almost relaxing. After a minute of lounging, soaking in the realization of her new power, her thoughts quickly turned to something else warm and gooey. Already her monolothic cock had soaked itself in her arousal, the dark, pulsing rod slick with a sheen of pre. She wrapped a hand (or tried to!) around it, the other hand gently squeezing Mount Tit, and started on a slow, rhythmic stroke.

“Oooh yes!” If there were any windows left in the world, that moan had just shattered them. Her hands picked up speed, giving herself into the pleasure with alarming intensity. The former inhabitants of Equestria, teleported far away by her magic, could only watch as their goddess put their homeland to good use. Even then, the ground tremored beneath their hooves as Twilight’s hips thrust upward with rabid, animalistic need. Errant droplets of precum, flung high into the sky, crashed back to the earth like meteors, creating new lakes wherever they landed. The scholarly parts of Twilight’s brain relished the idea that, by the time she was done, Equestria would need a new map.

She groaned, deep and guttural, as she felt her balls churn and rumble, reverberating deep into the very core of the earth. Fuck Equestria, she was going to rearrange the entire fucking world with the sheer force of her raw, unbridled lust. If she wanted to, she could fuck the entire planet straight into oblivion and the mere thought alone was so fucking hot. The pace of her stroking and thrusting picked up as she lit her horn, the blinding white aura of her divine magic enveloping her breasts so that her other hand could join its twin in more effectively stroking the towering monolith of her cockflesh.

Faster and faster she pumped, her heartbeat quickening as she felt her climax rapidly approaching. Idly, through the haze of impending orgasm, she leaned down and gave her cock a tentative lick, sending an electric surge of pleasure down her spine. “Fuuuuuuuuuck,” she moaned breathily as she felt an almost burning sensation at the base of her shaft, like fire and electricity and sex. “I guess...” she groaned, her breathing quick and shallow and growing quicker and shallower with each passing second, “...I guess this means that the magic duel has - ngggggggggh no not yet - haaaaas cuuuuuuuuuuming!”

Twilight’s pun was interrupted by an explosion of pleasure, the burning heat moving up her shaft before erupting into an orgasm that put most actual volcanoes to shame. The flow of cum was so staggeringly massive that there wasn’t a measurement of volume that could accurately describe the amount that surged forth from her cock, carving an arc through the air before thoroughly coating all of Equestria – and then some – in her beyond copious fluids. Ocean after glorious ocean of cum, with more and more coming. The oceans themselves slowly disappearing beneath a tide of creamy white. Her hips locked in place at the peak of her thrust, arms rigidly steadying herself on the ground while her cock flailed wildly like a hose turned up to the highest setting from the sheer force of spunk, spewing her payload everywhere, more and more and more until everything – everything – was coated in a thick layer of sperm, and then another few spurts for good measure.

And then, just when she thought she was winding down, the flow picked up again. A seemingly inexhaustible supply of cum, slowly petering down until it almost seemed to be over only to burst back to full force again, over and over, seemingly without end.

After what felt like months, Twilight finally started to come down. A few more weak thrusts and some tiny trickles (that still could easily fill a lake) and she was finally spent. Mostly. Her cock was still achingly hard and ready to go at any time she felt like releasing some stress. Being a goddess was tiring work, after all. Certainly that orgasm had taken a lot out of her.

“... Has cum to an end. There,” she finished, panting slowly as she basked in the afterglow. “Ha! Worth it.” Slowly, she pushed herself into a sitting position, cum flowing in to fill the space that her upper body had vacated as she languidly stretched. Idly, she licked her lips. “Mmmm, I taste goooood,” she groaned, bringing a cum-soaked finger to her mouth and eagerly sucking it dry. A salty, savory, creamy sort of taste. She swirled it around in her mouth like a sommelier savoring a fine wine before flopping back down, spreading herself as far as she could while she contemplated her next move.

This was what they meant when they said somepony was spoiled for choice, she idly mused. She had so much magic that she could do anything she wanted, with a limitless supply available to her should she ever feel like having more. Regardless, she had all the time in the world to come up with what to do next with her newfound divinity. She would sleep on it for now.

Dimly, she registered the almost invisible speck of pink still on her shoulder.
