The peaceful blue sky began to tremble. The trees and the grass pointed themselves toward the disturbance in the air, as if pulled towards it by gravity. The disturbance became a circle of color - mostly black, with the occasional swirl of color flowing towards the center. An indistinct blue shape seemed to approach from beyond the veil...

"Cower, morsels!" boomed the voice of Sonata Dusk, as her head poked through the plane of rippling light. She stepped through, sinking her boots into the grass, and Aria Blaze followed behind her.

"You mean mortals, stupid," said Aria, rolling her eyes.

"I'm not sure she does," said Adagio. "She already ate a few people back there. Sonata, you gonna eat any more people?"

"Maybe!" said Sonata. "I'm hoping this world has pizza people!"

The other two girls gave Sonata a look. "Pizza..."

"...People?"

"You know!" said Sonata. "People made of pizza! We're in another universe or whatever, so the people here could be made of anything! Haven't you read science fiction?"

"There's no pizza people here," said Sonata. Don't you recognize it? This is Equestria."

"Really?" said Sonata. "It's smaller than I remember."

"It should be smaller," said Aria. "We were planet-sized back in the human world. Why are we only like..." she looked down at a tree and did some rough math in her head. "...Fifty feet tall?"

"I'm surprised too," said Adagio. "The song we used to travel here didn't affect our size. I guess Equestria is just bigger than the human world. Going through the mirror must, like... scale you up or down so you're a normal size." She pushed over a tree with a gentle nudge of her boot. "This is good, actually. I'm glad we ended up at this size. Destroying the human world was fun, but now we're home. We can live here. We can rule here."

"So where in Equestria are we?" asked Aria.

"Not sure," said Adagio. "I sort of 'aimed' for the middle of Equestria, but I'm not sure where that would put us. Probably not too far from Canterlot..."

Aria turned in a circle, trying to spot any sign of pony settlements. "It's been centuries since we've been here," she said. "Ponies are probably living in, like, floating geodesic domes or gleaming dildo-shaped high rises or..." She craned her neck to see around a low hill, and around its edge she saw the roads and rooftops of Ponyville.

"...Or thatched-roof cottages." She said, shrugging. "Whatever. Once we do some more growing we can make them build us some nice modern temples."

"Yeah," said Sonata. "And we need to ask somepony to invent the internet, too."

"I'd consider that more of a long term goal," said Adagio. "But you're not wrong."

"Hello, tiny pony town!" said Adagio, her footstep booming on the road approaching Ponyville. "Hm, we should ask somepony what this place is called, just in case we leave some of it standing."

"Hello there!" said a small voice. The Dazzlings fixed their gazes on a small grey pegasus with a big pink bow in her wavy blue hair, hovering at waist height. "Welcome to Ponyville! My name's Flitter, and, uh... I think everyone would like to welcome you to our town, but... could you make sure you watch your step, please?"

"Oh, sure," said Adagio. She started to hum softly and lifted her foot above an abandoned cart. "You can watch my step too." She brought her foot down, turning the cart into splinters. "What do you think of that step?"

"It was beautiful," said Flitter, her mind already eclipsed by the siren's song. "I would give anything just to watch you destroy everything in your path, my Goddess."

"Mmm, still so good to be appreciated," said Adagio. She lifted her skirt, exposing her pussy. "How about you spend a moment worshiping my divine womanhood?"

"Yes, yes," said Flitter, flying underneath Adagio's skirt and perching on her pussy lips. Her face nuzzled into Adagio's cunt, and she licked her Goddess' lips and beat her wings to create powerful winds to vibrate her clit. Adagio moaned, surprised by the skill and enthusiasm of this new worshiper.

"Oh, wow," said Adagio. "Aria, you wanna take point until I cum?"

"Sure thing," said Aria. She lifted her foot over a patch of bare ground and brought it down, shaking the earth and making a nearby stone bridge crumble. From a small cottage on the edge of town emerged two ponies - one mint green unicorn, and one cream colored earth pony.

"Oh my gosh!" said the unicorn. "Bon Bon, didn't I tell you?"

"Tell me what, Lyra?" said the one named Bon Bon.

"Humans!" said Lyra. "Didn't I tell you? Didn't I say they'd be fifty feet tall? With pony ears?"

"No," said Bon Bon. "I mean, yes, they do look a lot like those... pictures you showed me... but those people are bigger than they're supposed to be, right?"

"Who cares!" said Lyra. She turned to the Dazzlings and stepped forward. "Humans... whoever you are, wherever you came from, please take me with you!"

"Oh my gosh!" said Sonata, patting at her torso with both hands. "She's right! We still look like humans! We didn't get our old bodies back!"

"You're just noticing this?" asked Aria. "She's right," said Aria to Lyra. "We're sirens. We just look like this."

"Whatever! Close enough!" said Lyra. "I'll do anything for you as long as I can just be around you!"

"Sure, I think we can honor that deal," said Aria. "But first, listen to this." She sang a tune under her breath, sending the entrancing notes straight to Lyra's ears.

"That's a really nice song!" said Lyra.

"Uh, thanks," said Aria. "Did it... change how you feel about us? Are you, like, more worshipful now?"

"No, I feel the same as before," said Lyra. "I just want to be around you all the time and do whatever you say, like I said before."

"Well, that's no fun," said Aria. "Sonata, you want her? I don't think I want to play with a toy I can't break."

"Sure!" said Sonata. She crouched and put her hand on the ground, palm up, and Lyra clambered onto her fingers. "So, little pony, what is it that you like about hu-"

"Boobs!" said Lyra. "I like boobs!"

"Oh cool!" said Sonata. "I'll tuck you right in here, okay?" She dropped Lyra into her cleavage, and the little unicorn nestled herself into the warm crevice. Sonata felt a burst of worshipful energy from the pony, and her body tingled. One pony's love wasn't enough to make her grow, but it still felt good.

Although the music hadn't changed Lyra's attitude, it had definitely affected Bon Bon, who was bowing down on the ground. "All right, you," said Aria. "Who's in charge here?"

"Mayor Mare, your worship," said Bon Bon, raising her head to look at Aria. "Or... Princess Twilight Sparkle, depending on, uh..." She furrowed her brow in concentration. "I'm sorry, but I don't totally know what either of them do. I'm not like super political? But Mayor Mare is in town hall over there-" she pointed a hoof towards the center of town, "And Princess Twilight is usually in the Friendship Castle." She pointed the same hoof towards the crystal castle on the other side of town.

"Twilight Sparkle, huh?" said Aria. "I know a Twilight Sparkle. Girls, I think we should pay a visit to the castle."

The girls strolled through town, making their way through the streets at a relaxed, confident pace. They sang, attracting ponies from every direction. A multicolored wave of pony bodies, instantly enraptured, flowed out of every house, every business, following their song. Adagio's voice was a little unsteady - Flitter was still under her skirt, taking her time, luxuriating in Adagio's pussy, letting its juices wash over her. Adagio almost wanted to punish the little pegasus for taking so long, for not bringing her to climax more quickly - but it was so fucking good. Flitter, somehow, was amazing at pleasuring giant pussies.

On their way to the castle, the girls had some fun with Ponyville. "You know, it's nice to be the right size to crush buildings again," said Aria, dropping out of the song briefly as she kicked over a building. Sofas and quills went flying as the structure crumbled, and Aria picked the tune back up.

"Yeah!" said Sonata. She found a cute-looking building - someplace called Sugarcube Corner - and hovered her ass over it, hiking up her skirt so that her bare blue butt loomed over its roof. Then she kicked her legs out from under her and let her ass drop, smashing the building flat. When she stood again, her ass came up covered in frosting of every color, and she swiped a finger across the smooth skin and brought a smear of frosting to her tongue. "Mmm!" she said, as sweet flavors filled her mouth. "Hey Lyra," she said, looking down into her cleavage, "do you want to lick frosting off my ass?"

"I want nothing more than to lick frosting off your ass," said Lyra. Sonata lifted Lyra from her cleavage, dropped her in her palm, and held her hand up against her left butt cheek. She giggled as Lyra's tongue went to work on her sugar-coated skin, licking it clean.

They were still growing, absorbing the love of Ponyville, but the population of the small town wasn't big enough to feed rapid growth. They'd picked up five or six feet by the time they arrived at the Friendship Castle, putting their heads level with the high balcony overlooking the main entrance. "Hey!" said Aria. "Twilight Sparkle! You home?"

The curtains behind the balcony parted, and three ponies walked through, coming to the balcony's edge with varying levels of trepidation in their eyes. There was something familiar about them, thought Aria...

"Erm, hello there," said a gray earth pony. "Welcome to Ponyville," She looked over the edge of the balcony at the crowd that had gathered behind the giantesses. "Seems like you're pretty popular already. Ah, is your friend okay there?"

The pony pointed a hoof at Adagio, whose body was rocking back and forth as Flitter brought her closer and closer to orgasm. She had her hand down her top, groping herself and gasping as the little pegasus explored and excited her pussy. "She's fine," said Aria.

"Okay then," said the earth pony. "Well, my name is Octavia, this is Vinyl Scratch, and this is Derpy. The three of us were deemed 'prominent citizens' - I'm still unsure what the criteria were - and we're tending to the castle at the moment. Is there anything we can do to make your stay more comfortable?"

"Twilight," said Aria harshly. "She around?" The little gray pegasus flinched when Aria spoke.

"Oh, right," said Octavia, "Well, Princess Twilight isn't around at the moment, but once she's back, we will let you know."

Aria grabbed a protruding crystalline branch from the top of the castle. "Any chance the princess would come back quicker if I started wrecking up her house?" She pulled, and the branch snapped off in her hand.

"Now hold on," said Octavia, stepping forward. "Just because you're big doesn't mean you can just boss everyone around. We may not have our princess, but we will not stand for-"

At that moment, Flitter was making her final push to please her Goddess. Now drenched in the nectar of Adagio's pussy, she wedged her body between Adagio's lips and filled her mouth with juice with each lustful lick. Her wings were beating at a near-hummingbird speed, creating a tiny cyclone that thrummed against her clit. The powerful, fleshy walls of her cunt began to throb and press against Flitter's body, signaling the coming climax...

When she came, clutching her body and twisting her heels in the dirt, she cried out musically, releasing a progression of notes from a low growl to a high, ringing peal. The walls of the castle had shielded the ponies from the music of the sirens, but this song had raw physical passion behind it. It pulled away their defenses like wet cardboard and molded their minds into love and servitude.

The Dazzlings gasped as they gained about ten feet of height in an instant, as Adagio's passionate outcry deepened their hold on the town. Their feet spread out, knocking aside the nearest worshipers as they expanded. Their heads rose higher, looming even further above the balcony. Flitter tumbled forward, falling into the expanded pussy she'd just got done pleasuring, sinking into an enclosure of slick, powerful flesh and sweet, potent musk.

"I apologize," said Octavia. "Our town is at your disposal, your worship. What service would please you most?" She bent her forehooves, bowing deep, and the other ponies on the balcony followed suit.

"Aw, is that all? No one's fighting back?" said Aria. "Ever since we became huge it's so easy to take over people's minds."

"This is great, though!" said Sonata. She lifted her hand from under her skirt, bringing Lyra back to her cleavage. The little unicorn was bloated with frosting and woozy from overconsumption of sugar, and she sleepily settled into the warm, snug crevasse. "It's never been easier to make friends! Maybe the three of us should live in the Friendship Castle!"

"Er, you are... welcome to live here," said Octavia, "Unless perhaps you'd prefer something more spacious?"

"You know, as long as you're being all worshipful and deferential," said Aria, "Maybe you'd like to finally tell me where Twilight Sparkle is?"

"She used the magic mirror!" said Derpy. "She went to a world of humans to help Sunset Shimmer defeat a trio of sirens who are using their music to enslave people's minds!"

"Oh no, that sounds dangerous!" said Sonata, with a look of concern. "I hope she gets back safe!"

"...Riiiight," said Adagio, who was only just recovering from her climax. Her face was flushed, her wobbling legs streaked with rivulets of pussy juice, but she'd fond her voice. "Well, it sounds like we don't have to worry about Twilight Sparkle. And once we have our fun here, we can move on Canterlot." She pointed at the distant mountains where the royal city stood.

"Oh wow, it's like, right there," said Aria. "I've been looking at the ground this whole time."

Adagio reached under her skirt and extended a finger into her pussy, pulling Flitter from within her folds. She popped the pegasus into her mouth, tasting her own flavor on the drenched pony's fur, then plucked her from her mouth. "Flitter, you did well," she said. "I might reward you with another visit to my pussy." Flitter responded with an outpouring of reverent gratitude. "As for the rest of you... the lucky ones will also have the opportunity to bring us pleasure."

"No dudes, though," said Aria, waving a hand dismissively at the crowd. "Stallions, back up a little. You can watch, I guess, but don't, like, make too much noise." Obligingly, the stallions walked about a hundred feet back, and the mares drew closer. There were some gentle sounds of disappointment from the stallions, but no anger - they had just been hoping they'd have the opportunity to pleasure their new goddesses.

Aria wrapped her hands around the highest tower of the Friendship Castle and used it to pull herself up, resting her hips on the balcony where Twilight's friends stood. She hiked up her skirt, shrouding the balcony under translucent green fabric and filling the pony's field of vision with smooth purple thighs and a tall, dripping pussy. "This balcony's pretty sturdy," she said, bouncing her hips on its edge, "Let's see if holds up while you girls get me off."

The ponies wasted no time. Octavia put her hooves on the balcony and sunk her head into the lower third of Aria's slit, licking up the fluid that gathered there, growing drunk on its flavor. Derpy beat her wings, hovering by Aria's clit and massaging it with her hooves and mouth. And Vinyl leapt over Octavia's shoulders and threw herself bodily into Aria's cavernous cunt, immersing herself in powerful, throbbing flesh. With her horn, she projected a deep bass note, sending a shockwave through the siren's inner walls.

"Ooh," moaned Aria. Her body squirmed, and the mares below the balcony were treated to the sight of her enormous ass shifting, the two purple globes undulating as pleasure shook her body. "These little ponies are good at working together."

"Maybe," said Adagio, "But I think they could use a little extra motivation." The giant siren rounded the castle and lifted her skirt, exposing her giant ass. She slammed her ass into the castle, shaking it down to the foundation and sending crystal fragments falling to earth. "Let's see if they can make you cum before my big ass crushes this castle into dust." She wiggled her ass, and the enormous cheeks hammered at the castle, sending cracks throughout the structure.

"Did you hear that, girls?" said Aria. "Adagio's fat ass is gonna smash up your little Friendship Fort. I might let you out of there if you make me cum before that happens. Don't be afraid to make it hurt." The ponies stepped up the intensity; Vinyl, fully inside of Aria, kicked at the giantess' throbbing walls with her powerful back hooves, and Derpy pummeled her clit at full force. Octavia, perched at the bottom of Aria's pussy, thrust her head deeper, sinking her face deep into Adagio's folds.

"Ooh, fun," said Sonata. "Hey Adagio! Is it okay if I play with your little Flitter?"

"Heh, that's a new name for it," said Adagio. "But sure, go ahead and get a few fingers in there."

"What?" said Sonata. "No, the little pegasus you were having fun with. Flitter is her name!"

"Ugh, don't learn their names, Sonata," said Adagio, still grinding her ass into the side of the Friendship Castle. "But sure, how can have her. She's just a toy, after all. Wouldn't want her to start thinking she's special just because she's pretty good at working a pussy." She lifted the hand that was still holding Flitter and tossed the little pony towards Sonata. The pegasus spread her wings mid-flight and glided to Sonata's outstretched hand.

"Ooh, so I have you," said Sonata, smiling down at Flitter. Turning her head to the crowd of mares, she said "And I have all of you..." She dropped her ass onto a bare section of cobblestone road. "Who wants to see me naked?" The crowd stomped its hooves and cheered (and the distant stallions politely agreed, still honoring the order to not "like, make too much noise"). "All right!" said Sonata, "Strip me!"

The mares split into groups, according to their preferences. Those who were enraptured by Sonata's smooth blue ass and her long slim legs went for the skirt, pulling it down with mouths and hooves. Those who were fascinated by her breasts climbed onto Sonata's torso and began to open her top, using all their strength to pull open the clasps that held it together. Quite a few of them - perhaps more than one might expect - went for her boots, combining their efforts to push them off her her legs. And a couple went for the scrunchie holding together her ponytail, rolling and playing in her streaked blue hair as they pulled it away.

Once her skirt was out of the way, Sonata brought Flitter down to her pussy and wordlessly held her against it. Flitter got the message and went to work eagerly, giving Sonata the same treatment she'd given Adagio. As before, the results were instant; with Flitter's hooves and tongue on her moist lips, and flitter's wings beating up a wind to pummel her clit, Sonata writhed and shook, throwing off some of the mares that were still stripping her and knocking others aside with her flailing limbs. But they were undeterred, and they returned to their work just as quickly, carefully pulling the boots off her kicking feet and the top off of her squirming torso.

Once she was nude, the mares swarmed her, and she giggled, still writhing from Flitter's attentions, as hundreds of hooves sank into her skin. Little pony tongues licked her bare, fragrant skin, from her lips to the soles of her feet, and her flailing arms punched and swept aside nearby buildings, turning everything around her into rubble.

Meanwhile, Adagio was grinding herself into the Friendship Castle. The castle's exterior had a rough surface, but just as in the human world, the siren's body was practically invincible. She bent low and lifted her ass, rubbing her vulva against the castle, and the rough, crystal-lined surface sent shockwaves of pleasure through her clit with every touch. She went harder, craving greater stimulation, and her ass bumped harder and harder against the castle, sending spreading cracks through the crystal trunk of the tree-shaped palace.

Octavia, whose hooves still rested on the balcony, stumbled and spread her legs to retain her balance as Adagio's ass shook the castle more and more. Derpy, still hovering by Aria's clit, had an easier time staying on task, although Aria's squirming body was always a moving target, and the huge, fleshy nub of her clit was growing bigger, ever so slightly, as the ponies poured their love into her. Vinyl was still inside of Aria, thrumming the walls of her pussy with magical bass drops and kicking at them with her hooves.

"Fuck," gasped Aria, the high tower of the castle crumbling slightly in her hands. "Not bad so far, little ponies. But you're not rough enough. Not mean enough. I want you to treat my pussy like you fuckin' hate it."

"She's not kidding," said Adagio. "If you want to make her cum before this castle collapses on top of you, you're gonna have to beat the shit out of her pussy."

The girls took the advice to heart. Derpy got her mouth around as much of Aria's clit as she could, and she drew her teeth across it. She was at no risk of doing any real harm to the indestructible body of the giantess, but she was able to deliver a cocktail of pleasure and pain to her Goddess. Octavia, neck deep in pussy, licked furiously, moving her tongue at lightning speed. And Vinyl picked up the tempo of her magical music, hammering at the wet walls around her with 200 brutal beats per minute.

Sonata was still on the ground nearby, mares swarming over her. Lyra, roused from her sugar crash, was sucking at the tip of a nipple that was as big as her body, massaging its circumference with her hooves. Another pony, with a light purple coat and a berry-themed cutie mark, was lying prone on Sonata's lips, licking at the soft skin. Sonata opened her mouth and let the mare fall halfway in, and she ran her tongue over her lower body, tasting the rich berry wine that her pony pussy produced.

Down below, two other ponies had joined Flitter in attending to Sonata's pussy. Her body was writhing violently, her cunt throbbing and pouring with juices. Her hands pounded at the ground, shaking the earth and crumbling buildings that her flailing arms hadn't already wrecked. Each beat of Flitter's wings spun the air around Sonata's clit, sending sensations deeper and deeper into her, rocking her core with waves of force. Sonata cried out, gasping and groaning as her pussy clenched and orgasm electrified her body. Flitter didn't let up, still pounding her clit with powerful winds, and Sonata's pussy throbbed over and over.

And nearby, Adagio rubbed herself to climax on the outer wall of the Friendship Castle. Groaning and clutching herself, she slammed her ass into the castle, finally smashing the base of it and sending the castle toppling forward. The ponies trying to make Aria cum responded with panic - Derpy clutched at her clit, squeezing it between her hooves. Octavia, feeling the balcony go out from under her, held tight to Aria's pussy, dangling from it by her forehooves. Vinyl, still inside of Aria, emitted panicked, irregular pulses of pounding bass, battering the pussy walls surrounding her.

And all together, they finally made Aria cum. Her body fell to the ground, like a marionette with its strings cut, and she whimpered as her body was wracked with climax. The brutal pounding in her pussy had paid off with an earth-shattering orgasm, and her body tensed and released powerfully, almost violently, as her climax rose and fell again and again.

In the ruins of Ponyville's town center, the Dazzlings lay writhing, cumming, until their moans went silent and their bodies went still. They lay like that for a while, basking in their dominance and the triumph of their pleasure, while the ponies of Ponyville stood ready for their Goddesses to command them again.

"This was fun," said Adagio. "I'm glad we got to play around with a little village before we moved on to greater things. I don't think there even was a town here last time we were in the vicinity of Canterlot."

"There's barely one here now," said Aria, surveying the damage they'd done.

"I forgot how cute ponies were!" said Sonata, who was holding Lyra in the palm of her hand and carefully grooming her hair with a tiny brush. "Can we keep them?"

"Of course we can keep them," said Adagio. "We're going to take over the whole world. We'll be keeping all of them." She looked out at Canterlot and sighed. "You know what I miss, though?"

"No, what?" said Aria.

"Resistance. The Rainbooms were the last ones who ever fought back against us. That was fun, right? And before that, Starswirl the Bearded?"

"That wasn't fun," said Sonata. "He threw us in that mirror, and we ended up in a world without magic, and we had to be humans instead of cool scaly floating horses." She looked down at herself. "Oh my gosh!" she said. "We still look human! We didn't get our old bodies back!"

Adagio quirked an eyebrow in genuine disbelief. "Uh, yeah," she said to Sonata. "You already..." She sighed. "Whatever. I don't like losing either, but that's the best part. No one is powerful enough to beat us now. Not Starswirl, not the royal sisters... we absorbed the power of an entire planet, and now we're unstoppable. So we might as well have some fun with Equestria before they're all bowing to us, right?"

"What are you saying?" said Aria.

"I'm suggesting we give Canterlot a little advance warning," said Adagio. "Send an emissary to the princesses. Let them mount their defenses. Put up their magic shields. Mobilize the royal guard. Let 'em fight back. In the end, they'll still be ours. Oh, Flicker!" she said, and Flitter flew up to the level of her face, awaiting instruction. "Fly to Canterlot and tell the princesses that the sirens are here to bring Equestria under their rule. Tell them of our power and beauty. Make it, like, super obvious that you're being mind controlled."

"I will!" said Flitter, looking wide-eyed at Adagio's cruelly smiling face.

"Do a good job," said Adagio, "And you'll be my favorite. You'll be the first to attend to my whims. My pussy will be your playground, my breasts will be your bed. You will spend every moment in my service, you will have the pleasure of doing exactly what I tell you to, every hour of every day."

Flitter almost fainted, imagining what it would be like to be the favorite servant of her Goddess - but she kept her composure, turned herself around, and set off for Canterlot as fast as her wings could carry her.

"Are you actually going to make her your 'favorite'?" asked Aria, making exaggerated air quotes.

Adagio scoffed. "I dunno. Maybe? Until I get bored with her? That's the nice thing about absolute power, girls. No one can make you keep your promises."
