Cozy Grow

Cozy Glow casually strode down the streets of Canterlot, taking in the sights from on high as she made her way to the castle, casting a lengthy shadow. Ponies gawked up at her stupendousness, paralyzed as her heavy steps left cracks in the thoroughfares. While the durable roads were just wide enough to admit her, for now, Cozy nevertheless made a show of occasionally juking her hips to the side, pulverizing ornate towers, relishing the resulting thrill of superiority. After one such structure crumbled to dust, shattered with minimal effort, Cozy watched a unicorn below scream and run from the falling debris, laughing as the stone peppered her toes. "Oh, don't worry too much! You're my tiny ponies, or you will be soon. I won't hurt you intentionally, unless you dare get in my way. At least not right now. Maybe later, who knows? Rulers get to be fickle and demanding, after all!"

However, a flight of gold-armored pegasi emerged from the clouds, diving at her with spears in their hands and battle cries on their lips. How cute, Cozy thought, noting their size made the valiant charge in V-formation look more like a small swarm of cicadas to her than anything remotely threatening. To rub in what she was about to do, she even angled her chest towards them, arms impishly behind her back. With the skimpiness of her armor, she was practically wide open to a killing blow for a second or two. But just before they could reach her, she cast a wide cone of chaos magic at them, instantly transforming the unified squad into an assortment of balloons in miscellaneous colors and shapes. The ends weren't tied, so they deflated with high-pitched noises, zooming in erratic loops before flopping onto the rooftops.

Witnessing this, a second group halted mid dive, delicious hopelessness written on their faces. Cozy's smile stretched as she watched them cower and struggle with themselves as some flapped backwards in panic. "I did warn you. I know foals less stupid than your buddies were just now," she said. Her fangs, each longer than a greatsword, flashed in the sunlight as she paused to lean against a sturdy five star hotel, the view from seven levels of balconies - the ones not crunched to bits - now obstructed by her back and ass. Though it was probably an improvement, honestly. "You should probably get used to listening to me soon, if you don't wanna end up as who-knows what!"

After letting that sink in, Cozy Glow left the cowed pegasi behind, once more resuming her course for the palace, crossing the many blocks in only a few steps. No more ponies launched futile attacks against her, either because of deference or the realization of how utterly futile such an attempt would be. The castle walls, a challenge for many invaders to bypass, she just stepped right over, giving the remaining guards stationed inside a flash of her tantalizing pussy, still wet with excitement. She could have simply flown straight into the courtyard, but where was the fun in that?

Ignoring the plant life and statutes being trampled, Cozy Glow closed the distance, noting with disdain that Canterlot Castle was still taller than she was. Even discounting the uppermost towers, the alabaster building had a few feet on her. Hopefully, that wouldn't hold true for much longer. Spying the throne room on the top floor, Cozy idly wondered which of the princesses would be present for her to utterly humiliate. Not wanting to delay her rise any longer, still standing on the grass, she brought her upper body through some of the large stained-glass windows with a crystalline crash, her chestplate banging into the marble floor as her weighty breasts spilled into the room, followed by her head.

Inside stood Twilight, Celestia, and Luna in full regalia, their imperious posture shattering as readily as the glass. Their faces spun from the front doors that they'd been watching to where Cozy had broken half of the wall to their right with her partial entrance. "Alright, you has-beens," Cozy began. "Equestria is mine now, whether you like it or not!"

"Cozy Glow, is that you!?" Twilight exclaimed, eyes wide and zipping across her body frantically.

"In the flesh! Though I get why you'd be confused," Cozy nodded patiently, her horn punching a hole in the ceiling. "I've gained a lot, lot more of that since we last saw eachother. Flesh, that is. Tons and tons, all brimming with power!"

Celestia, however, did not turn tail and fold, instead holding her ground. "S-Stand down, Cozy Glow!" she instructed, with an extremely rare stutter of lost composure. Determination could only counteract so much, in the face of Cozy's colossal presence.

"Do not do this!" implored Luna. "If you cease further acts of aggression, and try to repent, we may be lenient in your punishment. That chance was not afforded to you before, but it can be yours if you choose. A better path, the right path." On the surface, she sounded sincere, but Cozy could tell: Luna just didn't think they could win. The oh-so important princesses were scared out of their wits!

"You think I'm gonna quit? When I'm this far ahead?" Cozy giggled. "You can take your 'redemption' and shove it! The right path is whatever path I like, silly! Everypony else who tried to stop me is gone, from Tirek and Chrysalis to those six really old guys."

"The Pillars!" Twilight gasped, her brow lowering in righteous anger as she stepped forwards. "What did you do to them?"

"I actually brought them here, in a sense," Cozy confirmed. "No need to thank me, O puny Princess of Friendship. They all ended up right where I wanted them. Well, almost all of them; I was saving the best for last." Tilting her head playfully, she added "I suppose I can show you."

With that, Cozy Glow lit her horn, levitating the unconscious body of Star Swirl - stripped of his robes - from where she'd stored him in her cleavage. There'd been more than enough room to keep him totally invisible, sandwiched by her boobs, and the space he'd occupied closed with a soft slapping sound as she extricated him.

"No, put him down!" Twilight exclaimed, desperately reaching out with her own magic to pull him to safety. Their differently-colored auras clashed around him, bright pink trying and failing to overtake Cozy's red. As Cozy slowly moved Star Swirl upwards, Celestia and Luna, seeing their opening, leveled their own horns at Cozy, firing intense beams at her head.

Cozy kept a straight face until the magic struck, when she shut her eyes in bliss. The beams were pulled into her snout like a heavenly aroma, the diarchs crying out in pain as their well of magic was drained from their bodies, absorbed automatically.

"NOOO!" Twilight wailed, running to where Celestia and Luna had collapsed. In another circumstance, Cozy would have wanted to behold the grief-stricken expression Twilight wore as she fitfully cradled the others. However, with Twilight distracted, she was free to finish bringing Star Swirl up to her mouth. Wanting to time it for the best effect, Cozy swallowed the stallion immediately, his body's passage into her stomach barely visible at her current size. Which, judging by the sudden tingle under her skin, was changing.

"Mmm, that's the stuff..." Cozy sighed as the reserves of three of the world's foremost spellcasters added to her own. Her ears flushed and her body shook with the sensation as she became even mightier, her form heaving with fresh mass as her expanding silhouette cut through the stone of the throne room. Straightening up again, Cozy Glow savored the feeling of growth - almost as good as masturbation - as her body shattered the rest of the throne room wall, eclipsing the uppermost reaches of the castle. She must have been three hundred feet tall now, at minimum, by the most conventionally measurement, though her others were equally enlarged. Cozy's boobs and butt became deliciously huge, probably enough to smother a cottage. The alicorns beneath her, tall as they were, now stood at the meager relative size of slightly less than two inches. Only Celestia and Luna, sprawled on the floor, witnessed her latest surge with undisguised shock, Twilight busy fussing over them.

"I'd say that was a good try, but it really wasn't," Cozy quipped, in her sing-song voice, or rather, her newly seductive, deeper version of it. "Thanks so much for the magic, girls! It'll really help cement my new place as Divine Empress Cozy Glow, Her Gigantic Majesty and Overlord of All Ponykind," she proclaimed, throwing her arms wide with a laugh and another jiggle of her dwelling-sized bust. "You can just call me Empress, though, if all those big words are too much for your itty-bitty heads."

By this point, Twilight had refocused on Cozy, and she was currently rather speechless, her mouth working as she processed what had happened, fists clenched at her sides.

Suddenly, Rainbow Dash poked her head out from behind the raised dais where the thrones rested, speaking in an uncharacteristically high, squeaky voice. "Uh, I don't think the plan's a go anymore, Twi."

Twilight turned back to face her, meeting Rainbow's eyes for a long moment. "Come on out," Twilight eventually said, all trace of resolve absent from her tone. "We need to regroup."

At this, her friends emerged on both sides of the thrones, the five ponies, Spike, and now-useless Discord rushing to meet her alongside the still prone Celestia and Luna. With a bitter high-angled stare of undisguised pain and contempt, tears in her eyes, Twilight lit her horn, charging a spell as they ran or flew to her side.

Still partially delighting in the feeling of her glorious new magnitude, it took Cozy Glow a moment to realize what Twilight was about do: she was going to teleport them all away! Who knew what sort of plan she'd think up to deal with her later? Whatever it wound up being, Cozy knew it would be annoying, and thus was not about to let that happen. "Oh no you don't!"

A blast of unfiltered chaos met Twilight just as the last of her friends reached her and she cast her spell. When the lot of them disappeared with a pop, Cozy was livid for a split second, thinking she hadn't reacted quickly enough. That is, until she felt something upon her tongue that hadn't been there prior. Perplexed, she reached into her mouth with a tree-sized thumb and index finger, grabbing the intruding object and holding it up to her wide, demonic eye, squinting.

It was Fluttershy, equally confused. At least, until she realized where she was, meeting Cozy's stare. Then, she stiffened, trying to fly away, but her wings were locked in the iron clutches of Cozy Glow, pinned by her fingertips.

"Huh," Cozy blinked. "How'd you end up there? Maybe... the chaos magic messed with the teleport by scrambling the end locations?" As the implications of this solidified, Cozy cackled boisterously. "Oh, that's too rich! The bestest friends in Equestria, all alone who knows where! And without their kindest flunkie, they won't be able to use their stupid Harmony on me at all!"

Fluttershy reacted to this by putting up a brave face, but it was child's play to see the sheer terror underneath. After a long pause, she spoke. "P-Please let me go. I won't hurt you, I promise. My friends need me more than your s-stomach does."

Cozy snorted, her breath ruffling Fluttershy's mane, tail, and ankle-length sundress. "The chance of that is fatter than my ass! And in case you hadn't noticed, my ass is really fat."

Furrowing her brow, Fluttershy took a slow, wavering breath. "You're k-killing ponies, Cozy! You must know in your heart how wrong that is."

But Cozy just grinned and shook her head. "Fluttershy, you always were so naïve. Your princesses are gone now. Old-timey morals don't apply to those with power. Equestria is my toybox! So, I can use you, wherever, whenever. Dolls don't get to make choices."

Eager to hammer this point home in the most debased method her devious mind could conjure, Cozy Glow transferred Fluttershy to her other palm, which was larger than a king-sized bed for the meek mare. Cozy held her wings in place with her horn, Fluttershy lying on her back. Then, she tore Fluttershy's dress - slightly damp from the moment in her mouth earlier - off of her body with a pass of her clawed fingernail. The outfit fell away, exposing Fluttershy's bra and panties, which matched her skin tone.

At least, they did until Fluttershy grew very, very pale, looking from her partially unclothed body to Cozy's humongous, smirking visage. "O-On second thought, being eaten doesn't sound too bad. Circle of life, and all that."

"Good, because that's what I'm planning on doing." Cozy confirmed. "After I've made you scream."

With that, Cozy elevated Fluttershy's resting place to her lips, stretched to the side to expose her predator's teeth. With great care, Cozy pressed the tip of one of her fangs, now the size of Fluttershy's whole body, against her collarbone before slowly running it down across her front, ripping her undergarments apart. Then, she grabbed them in her lips, licking the barely discernable items into her mouth as Fluttershy watched, her assets now exposed to Cozy's scrutiny.

Cozy giggled as Fluttershy moved to cover her chest with her arms, legs crossed. "Why the modesty? You don't have anything I've never seen before." Looking closely, Fluttershy's body was shockingly quite something, her hourglass figure even more well-cut that Chrysalis' had been, approaching Cozy's own as a paragon of the female form. After a moment, Cozy added "Ya know, maybe you should at least try to enjoy what I'm about to do to you. It is going to be your last experience, after all."

Fluttershy met her imposing gaze, despite herself. The poor mare was shaking so hard her shoes had fallen off, tumbling off Cozy's hand and starting a long fall down to the garden below. Her reactions were almost too rich, even with Cozy's sadistic streak on temporary hiatus. Still, she eventually pulled herself together, swallowing her pride and her remaining resistance. "R-Right... Empress."

There was the deference she'd been waiting for. Cozy's smile turned genuine. "Was that so hard? Since you're being obedient, I'll give you your reward."

Fluttershy was treated to an up-close and personal view as Cozy began, bringing one of her bat wings around and up to her front. Making a show of it, Cozy wet her tongue before licking her wingtip with leisurely, circular strokes, watching Fluttershy through lidded eyes. The intact remains of the throne room acted as a suitable background below, combining with her captive audience's pencil-thin nature to truly cement how utterly gargantuan Cozy had become. She was too massive to even dream of opposing, and Fluttershy knew it, only able to look on as Cozy Glow coated a minor portion of herself in natural lubricant.

"Ready or not, here it comes~" Cozy sang once she'd finished. The miniscule caretaker did not resist when Cozy angled her wing towards her hand, using the barest fraction of her arcane might to spread Fluttershy's legs open.

Fluttershy cried out sharply, biting her lip to cut off anything more as Cozy's tapered wing bone penetrated her pussy with enough force to smash totally through, bottoming out on the first thrust. Cozy couldn't be sure, but she assumed her womb had been violated, too. What she could be sure of was what she felt, and Cozy just barely detected Fluttershy's walls contracting reflexively against her wing, the tiny pulses almost ticklish.

Then, Cozy began to move, using the finest muscle control she could to fuck her plaything of the hour relentlessly. In all likelihood, the end of her membranous wing was at least twice as girthy as anything Fluttershy had taken before, exceeding the circumference of her arm. Despite being careful not to pull out, Cozy smiled sweetly as she inundated the mare with over a foot of solid, quick-moving mass, an organic jackhammer. She writhed upon Cozy's palm, each frantic motion being felt as she rocked against her bonds. Such a minor act on Cozy Glow's part, and what a reaction!

"Excellent, excellent," Cozy uttered, focusing on her amusing handheld possession of the hour. "Still, are those good spasms, or bad spasms? This is my first time doing this for somepony else, so if I’m being too rough, let me know by wailing in agony, or whatever."

The only reply she received from Fluttershy was a strangled gurgle. From the way her expression had wildly contorted, pupils dilating, Cozy couldn't tell one way or the other. Eh, guess she'd keep going until she got bored or Fluttershy broke.

As Cozy continued to jam herself into Fluttershy's pussy, she noticed more details. Was Fluttershy raking her nails across Cozy's skin to ineffectually attack her? What about the way her legs kicked out madly? Regardless, Cozy's own motor was beginning to rev back up, as she enjoyed watching Fluttershy's boobs flop up and down on her torso each time her wingtip fervently stroked her insides, not to mention the squeaks escaping her lips.

Reaching down with her other arm, under her metallic skirt, Cozy Glow began to massage her own folds, releasing a moan that carried far into the city. Her attention thus split, her wing's motions grew more erratic. At the same time, the magic pinning Fluttershy lessened, now keeping her only loosely tied to Cozy, as if on a string. The tiny pony's vagina was so tight, and Cozy's wingtip so relatively thick, that when combined, this led to Fluttershy flailing in her hand like a beached fish as Cozy's wing yanked her bodily all over the place, as opposed to her slipping off.

Cozy kept masturbating to the sight of Fluttershy's deteriorating state, her smooth, long, mane and tail now horribly tangled and disheveled from the treatment Cozy was giving her. Fluttershy gasped and squealed, her toes curling even as her legs clenched onto Cozy's wing for dear life, stiff, mothlike wings brushing against her giant palm.

"That's it," Cozy goaded, curling her own fingers inside her sticky pussy, which was in the process of overwatering a well-positioned tulip bed with her cascading excretions. "Feel me, experience me, only me. I'm your master, Fluttershy, your world, and soon, you'll never be able to leave."

Perhaps in reply, or perhaps because of the continued unparalleled thrusting she was being subjected to, Fluttershy's eyes shut tight, tears escaping at the edges and her back arching as she shouted another new word up at Cozy. "C-Cumming!"

With that, Fluttershy reached her peak, her pussy constricting Cozy's wing with as much vigor as her little self could muster, as if trying to coax out a reaction. Mouth open in a silent scream, Fluttershy's sweaty body rolled around in Cozy's hand. Well, until Cozy stopped driving her wing into her, the better to take in her overwhelmed expression, finally confirming Cozy's success at fucking her. All too easy.

After about thirty seconds, her toy went fully limp, Fluttershy's bared chest rising and falling steeply as she breathed. Fluttershy didn't try to flee, too weak and exhausted, as Cozy cut off her aura and plucked Fluttershy off of her now ever-so-slightly warmer and wetter appendage with a faint pop. Still searching around inside her own vagina for the best spots, Cozy brought Fluttershy up to one of her tent-sized, fuzzy ears and asked "Any last words?"

It took Fluttershy's brain a minute to catch back up the present situation, after she'd been so supremely dominated. Cozy heard a sigh before Fluttershy spoke. "I beg you, at least... don't hurt the animals."

"I wasn't going to, at least not the magicless ones," Cozy confirmed, taking Fluttershy over to her mouth. "Dumb bunnies and stuff aren't even worth my time. Especially when I could be touching myself instead." To punctuate this, she shoved another finger up her crotch, the ensuing jolt of her body shaking the castle's foundations as she was stretched wider.

"Good," Fluttershy said, hands by her sides, resigned and satisfied as she could be, given the situation. That was fine by Cozy Glow.

Without any more ceremony, she tossed Fluttershy into her mouth, rolling the national 'hero' about on her tongue for a bit before sending her down the hatch. At her new size, Fluttershy went down effortlessly, no more visible descending her throat than a drink would have been. And her power barely made Cozy any bigger at all, only a few inches.

Moreover, Cozy found she couldn't maintain her arousal. Even with both hands in the mix, her clitoris engorged and exposed to the breeze, her masturbatory efforts tapered off. It still felt nice, but no matter how hard she worked over her depths, it didn't get any more intense, the high from before evading her grasp. Without the sight of Fluttershy egging her on, Cozy's body wouldn't cooperate. Or could it be because she'd already 'achieved orgasm' once that day? Still, it was the first disappointing event of what had wound up as the best day of her life, and she couldn't help but express this violently.

"Darn it!" Cozy exclaimed, kicking out her leg and instantly disintegrating the elegant, tiered gazebo in its path, sending painted wooden shrapnel hundreds of feet into the air.

The moment passed, though, and the sight of the destruction she caused with such a basic movement cheered her back up. There was plenty more still to be done, Cozy realized, such as informing everypony of their new goddess. Today was only the beginning of her long reign as Empress, and she'd have plenty more chances to amuse herself - mentally and carnally - once she'd reshaped Equestia to suit her every desire. Slowly, a delighted, if nefarious, grin split her face.

"Now then," Cozy began, rubbing her dirty hands together as she surveyed Canterlot from her towering viewpoint. "It's time for some changes around here..."
