Rump Ruination

Twilight knit her brow and turned her head, looking at the eldritch runes she’d scrawled upon the floor and walls. It was one of the few occasions her castle was completely vacant, allowing her to enact the eldritch spell she’d been saving for just such an occasion. Though she’d initially stumbled upon the ritual in her youth, when she’d first begun ferreting through the Canterlot archive, she’d never really had the opportunity, or been brazen enough to try it - that was, until now.

When she’d been a filly, she’d had many great aspirations, from becoming a powerful sorcerer to finding the perfect coltfriend, although only a few of them had come to fruition. While it was true that she’d ascended from a unicorn to an alicorn Princess, becoming extraordinarily powerful, she’d never been lucky enough to find a lover. The lack of romance in her life was bearable most of the time, yet it had become increasingly disappointing as the years passed.

Her attempts at dating had all fallen flat, and she couldn’t put her hoof on exactly why. Her best guess was that her difficulty stemmed from a disproportionate ratio of mares to stallions, although another issue seemed to be that a great many of her would-be suitors were intimidated by her. A good number of ponies felt inadequate compared to her, from what she could gather, which had resulted in her love-life being nonexistent.

Having retained her virginity well into adulthood, and with her chances of finding a special somepony growing slimmer by the day, her sexual frustration finally got the better of her. Despite her glaring lack of amorous action, and her nearly-constant summons to deal with all manner of problems throughout the land, she was still very much a mare - a mare with marish needs. Double and triple checking the diagrams and symbols she’d painstakingly painted about the chamber, she glanced back at herself.

A particularly strange part of the ritual was that she had to wear something nefarious. Unfortunately for her, given her sunny disposition and magnanimous personality, she was left to make an educated guess as to what a ne'er-do-well would adorn themselves with. Most of the villains she’d confronted wore very little or nothing at all, although she hadn’t thrown in the towel - not by a long shot.

On her last trip to Manehattan, she’d procured an outfit that would fit the bill. Studded bracelets, fishnet leggings, leather-banded foreleg covers, and a tank top, all colored jet black, adorned her frame. To complete her ensemble, an ominous and admittedly edgy pendant hung around her neck. Admittedly, the getup was over the top and ostentatious, the type of thing a teenager would wear to garner attention, yet it would suit her needs just fine - at least, she hoped it would.

With all her preparations complete, having locked both the castle and chamber doors, she steadied herself and read the scroll. The final thing she needed to do was evoke the supposedly ancient and lustful spirit described in the text, an act which gave her only a moment’s hesitation. After waiting so long to get laid, she wasn’t about to let her nerves get the better of her.

Evoking her power, she closed her eyes, concentrated, and channelled energy through her horn. “Ego dominus libidinosa!”

A silent moment passed, then several more, before she summoned the courage to open her eyes. The room was unchanged, the sigils remained in place, and everything was just as she’d left it, or so she thought. Resonating throughout the chamber, causing her to take a step back, the strange vibration set her nerves on edge.

“Who summons…?” a deep, sonorous voice inquired.

“Um - Hi,” Twilight timidly announced, looking about for a source of the supernatural noise. “I’m Twilight Sparkle, Princess of Friendship, and I was wondering if -”

“I sense much lust in you, Mare,” it interrupted, cutting her off. “And I know what you’ve summoned me for.”

“Heh - I guess that makes sense,” she anxiously chuckled.

It should have been obvious that it knew why she’d called it, considering that’s expressly what the spell was for. The incantation would provide unfathomable carnal bliss to anyone brave enough to use it, yet it didn’t expressly say how it would do such a thing. Unsure of how to proceed, without knowing the nuances of dealing with some otherworldly sexual being, she raised a hoof to ask a question.

“My name is Xedayrd,” it flatly stated, “but that’s not important. What is important is that you present yourself…”

Blood rushed to her cheeks, her marehood involuntarily winked in excitement, and her heart skipped a beat, yet she did as he asked. Leaning forward, she pressed her chest to the floor and arched her back. It was a bit embarrassing to put on such a shameless display, but she had nopony to blame but herself - after all, nopony had twisted her foreleg and made her summon a lecherous demon!

The unmistakable sound of something sniffing the air was joined by the sensation of hot breath upon her loins, causing her to stiffen. Looking behind herself, seeing no signs of her supernatural guest, she scrunched her snout. She knew good and darned well that something was appraising her goods, and pretty closely too, which was both disconcerting and vexingly arousing.

“It’s been eons since a virgin summoned me,” it smugly snickered. “You must either be exceptionally desperate or exceedingly foolish.”

“H...hey!” she blurted, straightening up and wheeling around.

Though it took her the mere blink of an eye to turn, she found herself facing a titanic, throbbing, crimson cock. She wasn’t sure what was more disconcerting, the absolutely titanic size of the disembodied dick, the fact that it was hovering in the air, or the fact that it appeared to be a monstrous parody of a stallionhood - regardless, the sight gave her a moment for pause. The most terrifyingly interesting thing about the appendage was that it was massive, nearly as big around as her torso and several feet long, although she didn’t have much time to admire it.

“Did I tell you to move?” the voice inquired, sending a cold shiver up her spine.

Fretfully reassuming her prior position, facing away from the hovering tool, her mind raced. “There’s no way that thing will fit inside me - you know that, right?”

“Oh it will fit,” it hummed, “although you’ll require a few enhancements.”

“What’s that supposed to - Gah!” she gasped, as what she could only describe as a shockwave of pleasure coursed through her.

The world spun, and she nearly climaxed on the spot, while she felt her body changing. Fighting through the bliss, she did what she could to see what the being was doing - still, without a mirror, she couldn’t fully appreciate what it had done. Her rump had ballooned to nearly quadruple its original size, her teats hung heavily beneath her abdomen, and her thighs had filled out considerably - all in the blink of an eye.

While her transformation was a bit off-putting, there was no denying how amazing it felt. Gnawing her lip, watching the gargantuan stallionhood positioning itself behind her, she spread and braced her legs. There was no way she was going to back down now, not after everything she’d done to get ready, and she felt certain that Xedayrd’s enhancements, as he’d so eloquently put it, could eventually be reversed.

“Such a alluring sight,” it murmured, as the prodigious cock glided up and down her slavering snatch.

Though her blush deepened, she didn’t budge a muscle or say a single word. For all she knew, if she asked too many questions or did anything to displease her guest, he may abandon her and leave her wanting! Subconsciously rocking back, she bore her not insubstantial weight against the profoundly meaty tip of the sorcerous shaft.

Simply feeling the hot, massive tool on her marehood was enough to cause her to drool from both ends - that being said, a part of her struggled to comprehend how in the world she could take something so large. She’d never been penetrated by something so big, let alone an actual cock, and the sensation of the hot, broad gland pressing against her was as frightening as it was arousing. As the gigantic tool slid upward and pressed to her entrance, she gnawed her lip.

Little by little, bit by bit, the pressure on her sex mounted. Glancing over her shoulder, seeing the shaft flex slightly, her pulse quickened. If the thing she’d summoned had seemed clear enough that it would fit, but she could scarcely believe that was true. As much as she would like to think she could accommodate the behemoth, it seemed an insurmountable task. Wondering how it would react to her taut hole, she felt monstrous stallionhood alter its course.

Her eyes widened, feeling the dick move higher and prod her backdoor. If the giant dong or the creature she assumed was controlling it thought that her ass was more pliable than her sex, they were dead wrong. For buck’s sake, she’d never so much as touched her behind, so there was no possible way that something bigger than her leg could cram itself in there! As she amusedly shook her head, dumbfounded by just how silly the concept of anal was, her pucker was forced open by the behemoth.

Gritting her teeth, with her marehood seizing upon itself, her once-chaste behind was violated by the horrifying appendage. The sensation was hard to describe, intense but somehow pleasant, and she was not prepared for just how good it felt. Only just stifling a moan, with her knees shaking, her eyes drifted to the back of her head.

“I told you it would fit,” Xedayrd mockingly purred.

“H...how did you - Glk?!?” her outburst was cut short, as something warm and slick forced its way into her muzzle.

She couldn’t say where the second dick had come from, or how long it had been laying in wait for her, yet it filled her snout all the same. Mercifully for her, the infernal dong wasn’t nearly as bit as the one worming its way through her guts. Though she could only see the lower portion of the shaft, since the first few inches were gliding over her tongue, she could tell it definitely wasn’t that of an equine.

Similar in color to the first, yet covered in soft, rubbery barbs, it wantonly set to fucking her face. Taken completely off guard, she attempted to withdraw and free her maw of the magical prick; sadly, with no body attached to the thing, it simply tracked the motions of her head and continued to blissfully hump away. The surprise sent her mind reeling, but it only took a moment for her other senses to be assaulted.

Rich, earthy musk flooded into her flared sinuses, tickling the primal parts of her brain, as salty and bitter flavors washed over her taste buds. The onslaught was beyond staggering, clouding her mind and robbing her of the ability to think. Over the span of a scant few minutes, she’d gone from perfectly normal to being spit-roasted by two enchanted dicks spit-roasting her!

Effectively trapped in place, her shock gave way to an unstoppable, almost nefarious desire. She’d imagined sucking somepony off before, and woken up to moistened sheets from the occasional perverted dream, but she could never have imagined she’d end up actually doing something so scandalous! Caving to her urges, she slowly closed her eyes and fixated on the wondrous sensations accosting her.

One of the strangest and captivating things of all was just how incredible getting her ass pounded felt. Only stopping once it had bottomed out in her behind, with its mammoth nuts pressed against her supple thighs, the demonic stallionhood steadily withdrew. She could practically picture the sight of her backdoor being drawn out, clinging tightly to its hot length, before it rammed itself back inside of her.

The first thrust was quickly followed by a second, then a third and a fourth, until she was being steadily pummeled from behind. She couldn’t wrap her head around the logistics of it, being plowed by something which defied all reasoning, but she wasn’t about to complain. Regardless of the absurdity of it all, she caved to her lecherous impulses and fully committed herself to the debauchery.

Synchronizing herself with the pair of disembodied dongs, she did her best to get them off - not simply to pleasure them, but because she was finally able to live out one of her deepest, darkest fantasies. An entire lifetime of sexual frustration came rushing forth, filling her with an inspiration like she’d never known. Losing herself to the moment, swallowing down a mouthful of cloying pre-cum, something lightly slapped her cheek and shook her concentration.

Peeking out, she discovered a second throbbing stallionhood inches from her face. She couldn’t say how long it had been there, but she quickly noticed that it wasn’t alone. Several more mystical, meaty appendates hovered around her, of various shapes and sizes, and she had little doubt where their intentions lie. Slowing slightly, seeing the knotted cock hover beneath her and to her groin, her heart skipped a beat.

Neither the member in her maw nor tool in her tush noticed or cared about the inclusion of other dicks getting involved, while they heedlessly pumped into her. Sure enough, in a matter of seconds, the additional horse dick found its way to her entrance and swiftly claimed her marehood. For the briefest moment, feeling it slip into her virginal confines, she assumed the additional intrusion would be some discomfort - she was dead wrong.

Much like the pistoning shafts making use of her gullet and colon, the sensation of the schlong filling her cunt was astonishing. The way the girthy shaft filled her, as the battering ram-like tip bumped against her womb, would have been pleasant enough, but the pair of ripe nuts slapping against her clit made the experience all the more wondrous. Her only complaint, if there was one, was that the overwhelming pleasure made it nearly impossible to think, let alone move.

It was like every fiber of her being was wracked with rapture, sending her skyrocketing towards release at an alarming rate. It was all she could do to hold herself upright and take sips of air when she could, as the dick before her rhythmically plunged into her throat. She couldn’t rightly say how long the trio had been pounding her, with each second seemingly stretching into a small eternity, yet her climax struck her like a bomb.

Her knees buckled, her marehood violently quivered, and a torrent of nectar gushed from her sex, as she was stricken with a mind-shattering wave of ecstasy. It wasn’t like she hadn’t had orgasms before, but this was an order of magnitude more powerful. Doing what she could to remain standing, she lost herself to the maddening sea of bliss. While she was mercilessly fucked by the trio, uncaring of how close they were to their limit, she only wished for one thing - more.

On and on the three floating dicks went, steadily moving harder and faster until they reached a fevered pitch. The cock in her snout blew first, pulsing and filling her muzzle with thick cream, yet the other two weren’t far behind. Flaring within her, with their crowns flaring out to nearly double their original size, the duo hilted and unloaded into her depths.

What felt like a tsunami of cum flooded into her bowels, filling her innards with an unbelievable amount of spunk, but the influx of seed directly into her womb nearly broke her. Locked against her cervix, pumping what had to be pints of jizz into her foal-factory, the smaller of the two stallionhoods claimed her. Despite having just cum minutes ago, a second, even more powerful climax hit her out of the blue.

Though she had no way of knowing it at the time, unable to see herself, her gut swelled and sagged under the immense weight of what had to be gallons of spunk. While a bit of the influx did manage to escape her, lewdly squirting from around the duo of buried lengths, the overwhelming majority was pumped seeped into every nook and cranny of her depths. She did have some inkling that something was off, feeling her weight gradually increase, yet she couldn’t care less at the time - that was, until the pair of equine dongs started to withdraw.

Apparently satisfied, or possibly eager to let their disembodied compatriots have a turn, the horse dicks hauled themselves from her battered cunt and ass. No sooner had the two cocks slipped free from her than a geyser of cream erupted from her gaped, blown-out holes. The relief of pressure, however undignified, was fleeting, as another two cocks quickly replaced the duo that had finished using her.

The concept of time faded, her mind went blank, and the onslaught of pleasure was never ending, while the cycle repeated itself. As soon as one of the dicks screwing her came, another immediately took its place. In the end, after untold hours of savage plowing in any number of positions, the once-regal Princess was left full of, and practically glazed from head to hoof in jizz.

Wearily lifting her head, she only eventually realized that the experience had come to an end. The cocks were still there, listlessly floating around her, yet not a single one made any move to sink its turgid shaft into her - any part of her. Rolling to the side, she unabashedly splayed her legs and waited for one of them to continue. Regrettably, not a single one seemed keen on taking her unspoken offer.

“If you wish for more,” Xedayrd began, speaking from the ether, “you must offer me something in return.”

“W...what?” she wheezed, her throat sore from the numerous, brutal swabbings it had endured.

“Next time,” it conceitedly cooed, as dicks disappeared one by one, “invite some of your friends…”

And just like that, with the offer tantalizingly laid on the table, the unseen beast disappeared. While Twilight had never gotten a look at the thing, she somehow knew it had departed from her presence. As she wallowed in the culminated mess of untold bucketfuls of seed, a preternatural euphoria settled over her. She could tell without looking that she was an absolute mess.

Her marehood and anus loosely hung open, with the cool air gracing her insides, while the cum slathering her coat gradually cooled and dried. She was in desperate need of a shower, and the entire chamber needed a thorough cleaning, but that could wait. For the time being, the only thought dancing through her cum-drunk brain was how she could fulfill the mysterious and depraved demon’s request…
