Tales of Celestia's magnificent rump have spread far and wide across Equestria. For many, that wide, plush rear would be enough. But Discord has something else in mind, and he wants more.

Tales of Celestia's magnificent rump have spread far and wide across Equestria. From the frontiers of Appleoosa to the highest towers of Canterlot, no flank is more adored than hers. Hushed whispers speak of a rear so temptingly wide and round that even the most heterosexual of mares (and gayest of stallions) feel their eyes drawn to its massive beauty.

But that's not enough for Discord.

The Solar Flank

Celestia’s royal bedchambers looked as they always did.

The princess wryly reflected on this as she stood, poised in front of a full-length mirror, scoping out her reflection. Her groomed coat was a pure white, her mane glimmering in the dim light. She looked perfectly regal—fit to slip on her golden regalia and descend the royal staircase to serve her cherished little ponies.

Tonight would be entirely less proper, Tia noted.

The room was non-descript for the occasion. Towering bookshelves lined the walls, with a crackling fireplace and a round, fluffy bed in the corner. Her eye casually fell on a telescope peering out the balcony window, and she smiled. Twilight would have liked the view from up here—Twilight, her most faithful student, the one pony she would share anything with.

Well. Perhaps that wasn’t entirely accurate. Anything appropriate, she amended. Though the list was extensive.

It was rather silly, though. She was the picture of regality: the sun incarnate, and with the composure to match...

But, then again, all mares had their indulgences.

She allowed a private, sultry smirk to invade her features as her horn lit in a practiced glow. A thin sheet of light shimmered into existence over the walls and floor. Not a picture or book was left uncovered.

It would make the morning much easier to deal with.

She turned back to the mirror, unabashedly noting her smirk. She spared a moment for vanity—admiring one of her more...physiologically endowed areas.

Oh, yes. That would be the main course tonight, she decided.

“Really, Celestia; I’ve always admired your ability to dominate a room through only the sheer majesty of your rear end.”

There it was—that twisted, distorted voice, its every inflection echoing from everywhere and nowhere. The disembodied voice of Chaos. Celestia’s grin spread.

Right on time.

“Good evening, Discord,” she said, keeping her gaze steady in the mirror. “A bit earlier than I expected. Then again, I would assume you’re operating on some twisted version of Equestrian time—after all, how often have you been late for tea, again?”

She closed her eyes, grin melting into a stoic visage. She took a moment to center herself, then slowly inhaled, breathing it out… and then let her eyes drift open as she gave her generous rear a brief waggle, grinning all the while.

“Oh, well—you know how it goes,” Discord’s voice replied from...somewhere. It was impossible to tell exactly where, annoyingly enough. “A draconequus is never late. He arrives precisely when he doesn’t mean to.” An appreciative-sounding whistle sounded throughout the room. “Though by the looks of things, I’ve arrived at precisely the correct time. It really is a shame that you’ve not directed that luscious-looking posterior in my direction, though. It’s not like either of us can see it.”

Tia opened her eyes. Her reflection—poised, regal, divine—smirked back at her.

“I’m rather surprised, Discord,” she said. “I’d expect you to be lurking in the shadows—it’s in your bones. But…”

She waggled her generous rump again—pointed at nothing in particular, just flaunting it for a pair of invisible eyes. “You’re managing to resist this—such a show of composure for you.” She chuckled, airily. “Why, I’m surprised you haven’t made a pillow of it yet.”

With what sounded like a long, held-out sigh, two white spheres emerged from the surface of the mirror. “You know, Celestia,” Discord said, the rest of his face materializing on the glass. “One really shouldn’t make invitations that they don’t intend to uphold.”

With Celestia’s attention taken up by the front portion of Discord’s body, she was too distracted to notice a set of claws creeping across the floor until they were right below her tail.

With a grin so wide that it split his jaw literally in two, Discord gave Celestia a wink as he pinched her generous ass, hard. “Mm...quite firm. I think I can see where your pride comes from, really.”

Tia’s eyes went wide as she felt a pair of claws reach back towards her most prided area, squeezing into them like a set of big, bouncy pillows. Her buttcheeks jiggled like a plate of jello, making her nerve-endings tingle like lightning as a cocktail of pleasure and pain fired up her spine.

She glanced back at the set of claws and grinned, a rather uncomposed giggle escaping her. “Firm? I hesitate to guess how you came to such an assessment—unless we have quite different standards of posterial buoyancy. But you know…”

She turned her head and winked at the pair of eyeballs peering at her. “Being an alicorn has its distinct advantages, as does a fully staffed kitchen. I wonder how I ever let myself go…”

“Well, my dear, once you’ve tasted one piece of chocolate cake… Well, let’s just say that you can never have just one.” Discord flashed her a fanged smile and stuck out his tongue; sitting on its tip was a plate holding a delectable looking slice of cake whose scent made Celestia’s stomach rumble.

His tongue returned to his mouth—along with the cake—with the sound of a cracked whip, and he licked his lips, his eyes drifting over her flank. “And I can certainly see that you haven’t stopped at one. Or ten, to be honest.”

It was quite the delicious sight, he had to admit. All those hundreds of years ago, Celestia had been nothing but skin and bones—a boring, unshapely sort of mare. “You’ve filled out nicely, Celestia,” he went on, drawing out her name.

“Filled out” was an understatement. Her cheeks held a certain pinkish tinge that many ponies instantly would associate with a matronly mother figure. Her other cheeks, meanwhile, held just the same sort of bright, creamy color, but just sang with each little twitch of fat and muscle. He imagined another pinch, the skin ripplingacross those taut curves, and shivered with glee. Why, one could almost say that the Princess bulged.

Celestia was on full display: shameless, and parading her rump in a manner that could knock an entire legion of royal guards out cold. And it felt wonderful. She would not go on the record to say her pride was an integral part of her personality—she was much too proper, too poised, too exalted to harbor such a base attitude.

“I do feel rather guilty that only your fingers are receiving the proper enjoyment,” Celestia lilted, her eyes glimmering. The centered facade had been entirely wiped away. There was nothing wrong if a mare was proud of her talents—and, more notably, her assets.

Celestia was fully aware—though she normally kept it hidden, lingering in her bubbling subconscious—that she had the largest, plumpest, most spanktastic and jiggly butt in all Equestria.

And tonight, she was putting it to work.

“Oh, but I’ve been told I’m quite the generous princess. The commoners sing their praises at the morning court, you know. ” Her grin vanished from Discord’s sight as she slowly began to turn, cheeks jiggling lightly as the draconequus claw-hands slipped off. As she moved, her torso dominated his sight, her spinning shadow offering a preview to future attractions.

A new shadow loomed over Discord, shifting and growing as Celestia assumed a more proper —though certainly less “proper”— position sure to delight the fan in the front row.

Though Discord couldn’t see it, Celestia’s smirk was positively greedy now.

Her butt—her huge, wonderful butt—towered in front of Discord, and in fact slightly over him, in all its plump, jiggly glory.

“Is this more to your liking?” Celestia said, holding her rump still for the moment. One couldn’t play all their tricks in the first act, after all.

“Oh, my.”

Only once before in her life had Celestia heard Discord sound properly stunned. This time, however, he sounded more than stunned.

He sounded flabbergasted.

“I—I—”

The smile on Celestia’s face broadened as Discord stuttered on. Oh, she would cherish this for decades.

“—If I may,” Discord finally said, “that ass is more than phat.”

“Oh?”

“It’s a damned planet.”

Celestia stifled a giggle as a loud slurping noise echoed through the room. It seemed that Discord’s drool had gotten ahead of him. In a teasing fashion, she pushed her rump up a few inches higher into the air, letting her generous mass bounce a little closer to his face.

“It’s marvelous—amazing—stupendous!” Discord smacked his lips, rubbing his paws together as he struggled to keep his growing lust in check. His voice became higher- and higher-pitched, his words blending together with his excitement. “It’s fucking enormous, is what it is!”

Celestia arched one thin, elegant eyebrow.

“It’s...enormous, that is.” Discord coughed. “My apologies. Slip of the tongue.”

“Of course.”

“Usually, I wouldn’t go for such vulgarity, Celestia—you know me well enough—but I do believe that in this case—” Discord swallowed, Celestia’s powerful ass filling his vision—”it’s more than warranted.”

Celestia smirked. “Goodness, Discord. You do know how to make a mare feel appreciated.”

Discord coughed. “Er. Yes. Right.” His knowing smirk returned. “Really, though! If I may be a rotten brown-noser for a moment, I would say that there are now two landmarks visible from space. The Great Wall of Gryphonia, and dat ass.”

After a few pregnant moments, she felt a soft weight against her waiting rump. She couldn’t see it, but a long, thin claw was trailing across the side of her right flank. It lingered upon her Cutie Mark, caressing the wide, plush curves of her rear as Discord’s lion paw pushed lightly against the other cheek. His fur was warm against her coat, her two cheeks spreading a bit wider at his touch. His paw sank into her flank as his claws pinched a bit more tightly—not enough to draw blood, but enough to sting—at her generous rear.

Discord looked down at the delectable helping of Celestia’s plump rear that sitting eagerly between his claws. He licked his lips again. There it was: the hunger, the insatiable need for something…

...different.

“It’s very nice,” he said. His voice was filled with longing, but there was an undercurrent of something that Celestia couldn’t quite identify. “But you know what?”

“Hrm?”

A wicked grin spread across Discord’s face. “Let’s make it even nicer.”

With that, he released his hold on her flank, the flesh falling back into place with a lovely little jiggle that sent vibrations fluttering all over the rest of her rump. It was then, just a moment too late, that Celestia recognized that familiar tone in Discord’s voice, just beneath that layer of lust and desire.

Mischief.

Discord snapped his fingers.

Celestia was wrenched from her exhibitionist stupor, still grinning like a pranking little school filly, when she felt it. Her ears had shot up as soon as she heard that telltale snap, her eyes opening wide.

“What are—”

A sensation not unlike a jolt of static electricity licked and tingled over her backside. She ran some quick mental calculations—Discord, the lustful, mischievous avatar of chaos had been drooling—fawning—over her luscious derriere like a teenage colt. With a start, she realized the buzzing sensation couldn’t be anything else.

She redirected her gaze towards the mirror.

Discord’s grin deepened as he watched his little trick take off. To the untrained eye, Celestia’s beautiful ass might appear unchanged. After all, it was already so large, so jiggly, so unapologetically round that any modification would seem superfluous. But not to Discord—oh, no. He had plans.

As he watched, rubbing his hands together, Celestia’s butt began to swell. At first, it was almost unnoticeable: barely the slight twitch of a perky, fully-curved rear. Yet as a few more seconds passed, ripples of fat and muscle spread across its plush surface, jiggling as Celestia’s Royal Posterior became a bit more divine, inch by inch.

Up and outward it grew, pushing up into the air and waggling around in an enticing little dance that Discord certainly wasn’t shy about enjoying. It continued to grow; by now, Celestia’s cheeks had swelled enough to bulge out behind her, with each individual cheek rubbing and pushing against the other.

Discord suppressed a cackle. From the look on Celestia’s face, there was simply no way she hadn’t already noticed. Good. That made it all the more fun.

Celestia had indeed noticed the results—there was simply no mistaking it. She was entirely familiar with her rump’s physiology and physics—she treasured the lovely bounce her cheeks gave as she paraded around the castle, apparently oblivious to the blushes she would induce from the royal guards—but she wouldn’t call it unrealistically huge. It was merely the jiggling result of both her alicorn morphology and the unchecked diet that had bestowed her with her perfect, perky rump.

Her wide eyes peered towards her rump,which  already beginning to perk up and swell like marshmallow in the microwave. The growth had thus far moved slowly, adding perhaps an extra inch on radius in each cheek. But they swelled in three dimensions—her buttcheeks were wider and pudgier. When she felt her ticklish rump bump against the mirror, there was no doubt that her cheeks were bulging.

“Discord, this is—” The words didn’t seem to exist. Not for something like this. “Oh, my. Oh my  goodness.”

“No, my dear—you don’t have to thank me.” Discord threw his head back and chuckled; at the same time, he swung his paw forward and smacked Celestia right on her swelling flank. It jiggled like nothing else, flopping up and down. His paw pulled back, leaving a rounded depression on the soft, warm flesh. Discord shivered with pleasure as he watched that cascade of rippling flesh, Celestia’s still-swelling rear reaching the size of a basketball in each cheek.

Discord shot her an evil grin. “But come now. We’re just getting started.”

He snapped his fingers again.

The growth slowed, paused…

...and then redoubled.

A reply died on Celestia’s tongue as Discord’s snap echoed through the room.. The rapid-fire pulses in her rear exploded, sending waves of electricity rocketing up her spine and lighting up every pleasure center in her brain. It was like the sagging sensation she felt after an especially gluttonous meal, except allotted further south.

Celestia glanced back at Discord, her mouth wide open. “You… you… you naughty creature,” she stammered out. “Sweet solar heavens… it’s so… I never could have imagined… it’s so big.”

Her buttcheeks had already outspanned the width of the mirror, and now their reflection resembled nothing less than two huge, fluffy marshmallows. She gave her rump an experimental bounce—and felt her knees buckle, her cheeks jiggling as though they were alive.

“Truly, my dear,” Discord said, stepping forward and holding his hands up in the air like some grandiose philosopher. “I can with all honesty say that a more wondrous flank has never been seen in all of Equestria.” He gave her rear end a playful flick.

The sensation of rolling flesh sent another shiver down Celestia’s spine. She moaned softly, biting down on her lip. With a sudden feeling of tension, she felt Discord take her oversized rear between his hands.

He hoisted them up, almost experimentally. These huge, incredible mounds of flesh sat patiently in his grasp, still jiggling slightly from when he’d picked it up. They were warm and soft, like giant slabs of dough—or putty—in his grasp. As he pushed further into Celestia’s cheeks, he felt a tightness: a taut sort of sensation that hinted at the sheer strength needed to hoist such a prize-winning posterior into the air.

Discord licked his lips and gave Celestia’s cheeks another squeeze, sampling his handiwork. “What do you think?”

Celestia didn’t respond right away. Rather, she couldn’t. Her brain was still swimming in the remnants of post-growth bliss as nerve pulses fired through her rump, which had finally ceased its swelling and settled on “monstrous.” Or “blubberous.” Really, Celestia wasn’t sure if a proper word had been invented yet.

Discord hummed to himself. If one were to insist on objectivity, each cheek had the an oversized beach ball, positively bulging off her hindquarters. They’d been tugged downwards by gravity so that they seemed to sway and jiggle perpetually if one cared to take a close-enough look.

Celestia glanced back at the mirror, and was seized by a powerful, mischievous sensation.

This was just one night—one night of fun. Couldn’t she let go a little bit?

Besides. How properly could one truly behave when sporting a rump that appeared to be seceding from its owner’s body?

Managing to recollect herself, Celestia flashed Discord a grin to rival his own. There was just thing to say, really.

“Bigger.”

She idly wondered how much matter would be able to fit between Discord’s jaws. If the sheer length that they’d dropped was any indication, the answer was quite a lot.

“B-b-bigger?” He sounded shocked, amazed. “Bigger?”

“Oh, yes.” Celestia smiled to herself. “Just a little bit, though. Wouldn’t want to go overboard.”

“Overboard...yes.” Discord sputtered for a few moments more. Each twitch of Celestia’s wondrous ass seemed to entice him, drawing him closer. “I—but—Celestia, you have an ass the size of the moon! Are you, in all seriousness, trying to aim for the sun instead?”

Celestia grinned cheekily. “Why not? It’s my domain, after all.” She gave her rear a little waggle; her Cutie Mark was now bigger than a pony’s head, the rays of the sun rippling out across her massive flank. “You of all creatures should know that there’s always one step more to take.”

Discord blinked, and then a smile grew on his own face. “Well, then,” he murmured, clasping his paws behind his back. “It would appear that I’ve been outdone. Bravo, Celestia. Bravo.”

He gave a mock salute. “You said you wanted them to be just a bit larger? Not too much, then?”

“Mm.” Celestia tilted her head, waggling her eyebrows. “I wouldn’t want to...overwhelm you with too much mass,” she said. “Now—are you ready?”

“My dear,” Discord breathed, the bouncing mass of Celestia’s flank filling the entirety of his vision, “I thought you’d never ask.”

He snapped his fingers one more time.

Celestia was smirking devilishly back at Discord as that familiar snap rang out. Her swaying rump was already a priceless treasure, one she wanted to retain and cherish, at least for tonight. Her pride was by now utterly unchecked. She would unabashedly describe her ass as huge—history held no other recorded examples of such a pliant, spankable, bodacious rump.

It was a good thing it was only temporary. Running the palace with such a rear would be...interesting. The doors would have to be widened and the throne expanded, at the very least.

Discord’s magic hit her in full force.

Celestia gasped, her legs buckling as she felt it again—that tingling pulse over her hindquarters—as the growth magic took hold. But she had grown used to the feeling and kept her eyes locked squarely on her asscheeks as they began to inflate once more. The two bulging domes dwarfed her torso now, as though her backside was an entirely separate entity.

She felt the tug of gravity on them as they started to droop—not sagging, but dangling, eclipsing her body’s retaining power over her spilling assflesh.

“Oh my. They’re swelling up rather nicely, aren’t they?” she observed.

A naughty little flare sparked in the corner of mind, though she pushed it aside with what little composure she chose to retain.

All in good time.

Discord gulped. “Magnificent.”

His Chaos Magic had outdone itself this time. Cotton candy clouds and chocolate rain were one thing, but this was one piece of magic that he wouldn’t mind becoming the norm. And he loathed norms.

Several feet of glorious, plush ass wobbled before him, those two cheeks stretching out until they reached the size of exercise balls. He swallowed again, feeling the blood rush straight to his head—as well as to another, lower place. Ah, well. He’d held out long enough.

Celestia peered over her voluptuous rump—which, to be honest, was no easy feat, considering the sheer size that she had to look past. Still, she managed it, and giggled as she noted Discord’s refreshed expression of absolute astonishment. “Oh, my. Yes, that’s a nice round shape, isn’t it?” She smacked a wing against one cheek, which rippled like a pool of jelly.

The still air was pierced only by exhilarated breathing sounding from behind her rear.

“Hm? Have I struck you mute? This is your handiwork, Discord. I wouldn’t expect you to be so silent in your admiration.”

Celestia paused, her eyebrows climbing up into her forehead as she noticed something new. “Or perhaps you’re just expressing it in a different way.”

Normally, due to a combination of a well-hidden sheath and little interest in any physical pleasures behind the simple joys of chaos, Discord had no visible genitalia. But here, with this glorious, godlike ass teasing him, his libido had reached unfathomable bounds—and his equipment showed it.

A long, thick shape had poked through the fur between his legs, its tip more rounded than the average stallion’s. Drooping below it, held in a scaly, reptilian sac, were two obvious testicles that were slowly growing in size.

Discord’s cock had barely begun to emerge, but was already more than eight inches in length. Ten, now—on and on it swelled, growing in size and circumference until it stood tall at what Celestia estimated to be a proud fourteen inches, and nearly half that around. It bobbed up and down, swelling just a bit more as if in imitation of Celestia’s enormous flank, and with balls to match. They hung below his cock, pushing his legs apart, and Discord bit down on his lip, one curled fang poking through as he felt them churning with lust and warm, eager seed.

“It’s...magnificent,” Discord repeated, breathing the word with obvious longing. “Celestia, I—”

He took a cautious step forward, dick swaying to the side and smacking against his thigh as he walked. His lust increased with each step he took, building until it reached a fire of wanton need and desire.

“I’ve never seen anything more beautiful.” He paused. “Well, except for that crossdressing Ursa Major. That was hilarious. But this…”

“A close second?” Celestia smirked.

“Very close.” Discord licked his lips. His lion’s paw was already at the top of his dick, stroking it lightly. It felt like all of the blood had rushed to his head and crotch, making the world—which, at the moment, were those two incredible asscheeks—seem to blur in his vision.

“My, Discord. I’ve never heard you speak so reverently before,” Celestia said, smacking the other cheek with her wing. Discord visibly shuddered, and she winked back at him as she gave her butt another hefty shake.

“I wonder how we could wrench you out of that stupor,” she wondered. The naughty glint in her eyes flared—she felt like she’d pointed a loaded weapon at the babbling draconequus. She took a step back towards Discord, hefting her rear higher into the air. “It’s a bit discomforting, actually. What happened to the gleeful cackles and vulgar exclamations?”

Her eyes went half-lidded, and she breathed out, as if to a lover: “Tell me what you want to do to it.”

“I’d smack that flank.” Discord took a deep breath and flashed her a wide grin. “I’d pinch it, and I’d slap it. I’d roll in it, and I’d take it in both hands and I’d have my way with it.”

“Go on.”

“I’d fuck it.” Discord froze, momentarily surprised by his own vulgarity—apparently, Celestia noted, with some amusement, “big colt” words weren’t quite his line of preferred chaos—but he appeared to recover soon enough. “I’d fuck it silly, using every inch that I had and then some until I’d covered its every square inch—inside and outside—with enough spooge to fill a small lake, and it still wouldn’t be enough.

“I’d hold it up in the air.” Discord was rushing now, his words blurring together. “I’d let it flow all over and around me, and I’d hold it up for all of the world to see. And I’d let them see it—every pony, every griffon, and every other beast on this damned planet—and I’d shout This is mine. This glorious, wonderful, enormous—” he licked his lips— “delicious ass.”

By the time he’d finished, Discord was breathing hard. His dick bobbed up and down, as if in generous agreement, and his balls throbbed with immense, unstoppable desire.

“My.” Celestia cocked a regal eyebrow. “My, Discord. You’re rather letting yourself go tonight.”

His snakelike tongue flickered out from between his teeth, and he flashed her another—could that be sheepish?—smile. “I’m not the only one, dear Princess.”

With a flash of a smile, Celestia lurched backwards, sandwiching Discord’s pulsing cock between her dough-like cheeks as she pressed him against the wall.

“But, this is rather special for both of us, isn’t it? One deviant night between deities?” She ground her cheeks against the wallpaper, smooshing Discord’s length between her bodacious bubble butt. “My rump doesn’t receive much attention, you know. It’s hardly proper for the ponies’ beloved princess to take note of her generous features.”

She leveled a greedy stare into Discord’s hazy eyes.

“So, if you would, please do not hold back. Praise thine princess’s posterior.”

Discord bit his lip as Celestia’s cheeks wrapped around his member, pushing against it with full force. They were so wide that, pressed against the wall like this, they spread from his knees to the top of his chest, clenching his cock and balls tighter than a vise.

He grunted, thrusting his cock between that full, rounded rump. “Full Olde Equestrian, eh?” he managed to mumble out, holding in a squeak as Celestia’s rounded flesh held tighter to his thick, veined cock. “Then allow me to say, my Princess, that thine posterior is amongst the planets in the heavens, placed there as if by some divine being above even myself.”

He could feel Celestia’s rolled eyes.

“The ways in which thou pricks! Mine prick are amongst the hidden magicks of the world,” he said with a broadening grin. He thrust harder, again and again, loving the way in which her soft, pliable flesh flowed between his dick and stomach, pressuring it from all sides each time he fucked her tender asscheeks.

“Unf—” Celestia moaned; from the way that Discord’s shaft had pushed against her enormous ass, it had shoved the excess skin forward in such a way as to brutally play with her clit. Each smack of flesh brought forth another wave of pleasure that swept down her spine, rippling across her flank like the waves of the ocean. Her feminine lips were already wet, her juices dripping down through her rump and falling onto the floor. “Harder. Praise me harder. Worship your Sun Goddess.”

“Tis a fair thought!” Discord hollered. Celestia had squeezed her cheeks even tighter around his thick, pulsing member; each thrust seemed to bring even more blood to engorge it. “To lie between a maiden’s fair legs—if even it can be said that said maiden’s legs exist any longer!”

It was true enough. Celestia’s ass had swelled up so much that it more than covered the top half of her hind legs. She smirked, her horn flickering to life.

Discord’s eyes nearly rolled back into his head as the soft, pliable flesh that he’d been fucking suddenly turned into firm, tight, rounded cheeks. It was as sudden as the shift from popped-corn cornstalks to prancing buffalo ballerinas, and the sudden pressure surrounding his cock was almost more than he could handle. The tight assflesh played with his cock, the taut curves teasing his churning balls with each new thrust.

His eyes narrowed. Oh, he wasn’t about to give in. Not now, and not ever.

“Passion! O, Sweet Love!” Discord gave Celestia’s now-tight ass a full-armed slap. He left a thick red mark, and Celestia let out a yelp of pain and pleasure. “By her fine foot, straight leg, and quivering thigh!”

Quivering it was. Celestia let her cheeks relax for a moment, letting them relapse into soft, pliable flesh. Discord sighed as the pressure was relieved, his balls whining for more—and then let out a high-pitched squeal as her ass re-firmed, squeezing his cock even tighter. Off and on; on and off. With each thrust of his cock between the crack of her ass, she squeezed it tighter and softer, masturbating him with each ripple of yellow across her horn.

“Well, Shakesmare? Whatever happened to your soliloquy?” Celestia sputtered out through labored breaths. Her ethereal mane was drooping slightly, her crown tilted down and jutting over one side of her face, framing a weary but mischievous smile. Her horn glowed again, and she gave Discord’s cock another emphatic grind with her now firmer buttcheeks. “Or, have you reached the extent of your attention? Too star-struck for words, mayhap?”

Thoughts flickered through Celestia’s head, many carrying rather uncouth words that were hardly befitting of a princess. Some fragmented vestige of her mischief-addled brain, it seemed, still clung to some semblance of ceremony.

She chanced a look over her shoulder, and her last shred of composure buckled.

“Oh, fuck me,” she moaned. She knew what was going on between her most bulging assets, but laying eyes on it like this sending another shiver down her spine. Her back legs wavered as the glow left her horn, her once taut asscheeks spilling downwards over Discord’s sack.

Discord sucked in a breath, his fangs poking over his lip and pinching so tight that they almost drew blood. That rear danced before him, drawing him in with its every jiggle; he could feel its soft mass enclosing his member, jiggling against his massive length with each twitch he made. That ass—that huge, glorious ass—filled his vision entirely. It was his whole world.

He licked his lips, his eyes flashing as a thought occurred to him. His whole world…

Celestia furrowed a sweaty eyebrow as Discord paused in his merciless thrusting. She saw his feral, lecherous expression shift, her jiggling mounds settling. She swore she saw him grin, though it was masked by his worshipful butt-struck visage.

Her brain received a dual-signal, an antiquated, icy chill of panic, and a hot surge of lust that shuddered up her back.

And then he was gone.

Her cheeks fell loose, hanging down as the hard rod spearing through them vanished, the two churning balls that had supported them from beneath disappearing in a poof of smoke. That pressure was suddenly gone, her flanks slapping against one another as her warm flesh moved back to fill in the vacuum that had been left in Discord’s absence.

Celestia blinked, her brow creasing. The space behind her was suddenly vacant, as if Discord had dropped through a trapdoor in the midst of one of his thrusts. Perplexed, she turned her head back, surveying the room—

“Ah!”

The sensation struck her from left field—a familiar shifting and churning of her bubbling buttcheeks, but more localized, this time. And it tickled. Her nerve endings were lighting up again, coaxing another childish giggle from her lungs.

It felt like somepony had gone to her rump with a feather duster, swirling around it in tight circles. Her butt didn’t merely tickle—she could feel it depress somewhat, like she was being rubbed in a precise pattern. It was almost as if somepony was…

Celestia suddenly felt her cheeks flush with heat.

“Discord,” she began. “Are you…”

Discord sighed happily, his eyes closed. “Ah, isn’t this just lovely, Celestia?”

He shifted his weight, rearranging his shoulders until they sank a bit deeper into the white, bouncing “ground” that enveloped him. His arms spread out, and began to sweep up and down along the folds of “earth” beneath him. His member bobbed up in the air above him, waiting patiently for its turn once more.

“What are you—ah!” Celestia’s tongue lolled halfway out of her mouth as Discord’s waving arms made her ass ripple in an even tighter spread than before. “You—”

Discord grinned up from his butt-angel. “Chaos magic has its advantages, my dear,” he sang out. “Shrinking down to more—mm—fully appreciate such a lovely rear is but one of many.”

His eyes flickered over to the side, and his grin became a bit toothier. “I’d be a fool if I missed this chance to explore.”

He squirmed across the spread of Celestia’s immense ass; even normally, it was a freak of nature, a giant larger than many ponies’ torsos, but from Discord’s shrunken perspective, it seemed like a miniature planet. As he moved, he did his best to do so in a snakelike fashion, his lengthy body wiggling across her rump.

Finally, after a brief trek across the asslands,  he made it to her crack. His grin spread even wider, and his eyes darted up to Celestia’s even larger face.

“Ready for the plunge?”

“Discord,” she warned. “What are you—”

“Cowabunga!” he cried, leaping off her ass and into the air. At his reduced size, he barely managed more than a few inches of elevation, but for his purposes, it was more than enough.

He dove between Celestia’s fabulous ass in perfect form with an audible schlorp; Celestia’s eyes widened as she heard applause from behind her, her head whirling to see a trio of Discords dressed in plaid suits, each holding a perfect score of ten above his head. She glared, and they vanished in puffs of smoke.

Her rump vibrated with each inch deeper that Discord dug, his serpentine body wiggling deeper between Celestia’s cheeks. She bit her lip, the sensation of her flanks slapping against one another almost too pleasurable to bear. “Discord,” she said again, a bit more quietly. “Where, exactly, are you going?”

“Oh, you’ll see, my dear.” Discord paused in his descent, resting his elbows into the plush walls of flesh around him. “I’ve got it all under control.”

Celestia raised an eyebrow. Discord had long since disappeared beneath her massive folds of ass, but she could still feel him squirming between them, swimming in that sea of flesh. “All right, then,” she said. “Just—”

Her eyes widened imperceptibly.

Discord had reached his target: a wide pink slit almost as long as he was tall. It was located at the very bottom of Celestia’s flanks, its surface soaked with her juices and flushed with warmth. He cuddled up on a particularly fine bed of ass and reached out a tentative claw—before giving up all hope of subtlety and just smacking Celestia’s labia right across the lip.

Celestia gasped, feeling just a bit wetter at the touch. “You naughty draconequus,” she murmured, closing her eyes. “So that’s where you were going.”

“Do I ever disappoint?” Discord purred. He ran his lion’s paw up and down the length of Celestia’s marehood, shivering with anticipation as the Celestia’s relatively huge folds swelled beneath his touch. Playfully, he slipped a paw inside, teasing her slit with a light pressure on the inside of her cunt.

Celestia sucked in a deep breath. It was a tiny, almost unnoticeable pressure, but it sent a spark of electricity through her tender folds, her back nearly arching at Discord’s light touch. “You—certainly have a way with mares,” she grunted. “I—I suppose you want me to be impressed.”

“Mm.” Discord glanced up at the ceiling of white alicorn ass above him and winked. Tenderly, gently, he held out his long, snakelike tongue, and dragged it along Celestia’s lips. It was a tiny touch, a mere pinprick of pressure on Celestia’s enormous vagina, but with eons of experience, Discord more than knew what he was doing.

For added pressure, he rubbed his throbbing cock against her folds, teasing it—and himself—with each pulse of blood through both sets of genitalia, keeping himself pinned between her thick assflesh one on side and her tender marehood on the other.

She had been angry, yes—being the personal perverted anatomical wonderland of a lecherous Draconuequs had not been in the cards that evening.

Then again, when did things ever go according to plan with Discord?

But the spasms and shudders pulsating up her spine and inundating her brain with waves of pleasure were a force like a tidal wave, battering and submerging her with ticklish tingles in her most prized areas. Her knees were buckling, their strength seized by the whimsical wrigglings of her living dildo.

“Discord—” she squealed, her inflection raising as he hit a particularly sensitive spot. Her words were laced with bemused affection. “Forgive me for stating the obvious, but this is quite unlike anything I’ve ever experienced before.”

“And I’m glad to hear that, my dear,” Discord’s voice echoed from deep within her ass. “I’m more than happy to provide, you see. After all—”

He slipped his arms into her clit, rubbing her walls. She let out a low moan, her sides trembling.

“—I’m here all night.”

A smirk crossed his face, and he withdrew his arm, soaked in her pussy juices. “As you will be,” he murmured.

Celestia let out a low sigh as the touching ceased. Her cunt felt raw: teased, but unfulfilled, aroused, but bereft of any real release. She waited, wondering when Discord’s touch would grace her marehood again.

It didn’t come.

All was silent in her derrière, with neither peep nor hide of the draconequus apparent from outside of that massive flank. A frown crossed Celestia’s face, and she winced, her lips suddenly throbbing with need. She wanted something more—

That frown shifted to a mischievous grin as an idea crossed her mind. If Discord wouldn’t finish her off, she realized, then he’d have to be punished.

“My,” she murmured aloud, just loud enough that she could be sure that Discord could still hear her. “I’m simply so tired from all of this playtime. Perhaps I should take a seat; give my tender rump a rest for a moment.”

If Discord had caught that, he gave no reply. Her smirk deepening, Celestia rocked back on her hooves, letting her rear fall toward the ground until it was just bare inches away—

“Grow back.” Celestia said, smirking. “I believe you’ve had enough of using my behind as your personal playground. I’d like to give you a different perspective.”

Her voice was sharp. Commanding, even, like she was handing down her sentence after Discord’s initial rampage of Equestria. For the first time that night, Discord felt like the reins had been yanked from him.

He didn’t like that. Not. One. Bit.

But at the same time, it thrilled him. Here he was: Discord, Lord of Chaos, master of unpredictability, and here was a mare with a huge—and admittedly gorgeous—ass, ready to crush him beneath her heel. Or hoof. Or rump, really. He supposed that it wondered how metaphorical you wished to be.

Still..

He raised his claws, fingers poised in a ready-to-snap position. He needed to shake things up. Change the flow of the scene.

Snap.

With a flash of white light, the space beneath Celestia’s ass suddenly was no longer vacant—instead, it was occupied by a rather bemused-looking draconequus. “I say, Celestia,” he began as her ass descended upon him. “You really do—mmph!”

Celestia smirked down at him, grinding her ass into his face as a cheeky grin flitted across her own. “I’m sorry?” she asked.” I couldn’t quite catch that.”

Celestia’s titanic buttcheeks plummeted onto Discord’s face like two giant, squishy comets. She felt his face smooshed between her smooth, supple assflesh, not unlike a massage she’d received from a notably abashed masseuse. She could feel the squashed draconequus’s protests vibrate against her sensitive inner skin, like somepony was blowing a raspberry back there.

“Now, now… honestly, did you think you’d be the one on top all night?” She gyrated her hips, rolling her bodacious bubble butt over Discord’s face, engulfing it entirely like two giant, squishy pillows. “Still… this was your entire plan. The regent of Equestria, unwittingly possessing the grandest flank in all of Equestria? I’d sooner expect a squirrel to ignore an acorn. Not much of a punishment, exactly. Wouldn’t you agree?”

Again with the muffled vibrations, sending tingles up her spine.

She couldn’t see the scene, not with her swollen rump blotting her view like a solar eclipse, but she could feel it. Discord’s face was entirely engulfed underneath her mounds, his snout wedged against her backdoor proper.

That lewd positioning sparked an idea for a delightful prank.

“I think there’s a certain potency of my rear that you won’t rather enjoy, Discord,” Celestia said, grinning like a schoolyard bully. “A side effect of letting one’s eating habits run rampant?”

Celestia paused to let Discord parse this information.

She heard only a muffled squeal beneath her, Discord’s snout squirming from side to side, but only managing to drive his face deeper into her rear. Her grin spread from ear to ear.

Discord swallowed, struggling not to let himself squeak. Admittedly, he could just snap his claws and have her off him at any time, but that would destroy the moment completely, and really—where was the fun in that?

He couldn't deny that the pressure of her oversized flank on his face and chest was almost painfully arousing—his engorged cock rubbed against the underside of Celestia's massive rump, groaning with a need to spill its seed—but the playful threat in her voice had raised a panic in the bottom of his stomach. Not to mention—if his suspicions were correct—a certain kind of rumble in the bottom of her stomach.

You wouldn't, he thought at her, eyes widening beneath her mounds of assflesh.

On any other night, Celestia would have been blushing tomato-red at their ludicrously juvenile situation. A forlorn corner of her mind was prodding her to lift up her (deliciously fattened) rump as would be proper—if only for a moment—but her aloof, prankster side held the reins and wasn’t about to give them up.

 And really: Wouldn't Discord laugh it off in hindsight?

"My, it's such a pity your snout is wedged in such an unsavory position." She wriggled her titanic butt over Discord's muzzle, wedging it more snuggly against her tailpipe proper in order to provide the illusion she was not fooling around. "Though I imagine you'd use more juvenile words than unsavory? More olfactory-related words?"

Her horn lit up with an illusion spell, and the churning in her belly grew to alarming levels.

Discord's mouth opened in a wordless scream as Tia's rump ground into his chest—and then quickly closed as he realized that her hole was in prime position above his snout. What do you want from me? he thought at her, knowing full well that she could hear him. That your ass is pushing my into the ground? That your large intestine is primed and aimed straight for my muzzle, ready to unleash a firing squad of incredibly pungent, vomit-worthy ass-gas? That the only reason that I've not teleported out from under you yet is out of some kind of morbid curiosity as to whether you'll go through with it or not?

He thought for a moment before adding, And that—if I may be so bold—the feeling of your enormous flank over my cock is quite nearly stupefying?

"Oh, but would I do it? Would such a majestic, proper, regal princess indulge in such a foul act, Discord? Would I truly go so far?"

As if to prove a point, she hefted up her swollen derriere. Her titanic cheeks hovered over Discord for a moment, but before he could take a proper breath, she slammed them back down, wedging his snout even deeper than before.

"Tell me, Discord. Does anything about this situation speak proper to you?

“Imagine if I actually did go through with this,” she said, her lip curling. “I'd hope the janitors have hazmat suits available."

Discord let out something resembling a high-pitched squeal. With a sudden jerk of his claws and a pop of air, he vanished from beneath her in a flash of light.

Discord rematerialized in front of Celestia, for once pining to place as much distance between the princess and her atomic weapon of a butt that was now squished against a bare floor. Taking heavy breaths, he glanced at Celestia, readying a scathing rebuke to the princess's heinous mannerisms—

She gently smiled, and with a light of her horn—

Pop

Discord disappeared in a flash. Before he knew it, he felt a huge weight across his face. It was soft, warm, and thoroughly moist. Panicked, he glanced back up—Celestia's Cutie Mark filling his vision, his sight was dominated by nothing less than the full glory of her ass. Her massive, rumbling ass—

"Now, now," Celestia murmured in between wriggles of her huge, pillowy ass, the rippling folds warping and shifting over his face as she wedged Discord's snout back. "You wouldn't want to leave before I've warmed you up now, hm?"

Her belly was churning like a tidal wave, the roar of her gut wailing like an approaching tornado of stink—one Discord knew would be bearing down upon him with moist gale force winds in mere moments.

Discord's eyes widened, his cheeks turning a sickly green. Oh, shi— His hips thrashed madly, his arms clawing at Celestia's massive rump in a vain effort to extricate himself. He could feel it coming, and he struggled all the mightier for it. Claws scratching, arms flapping, legs thrashing—

Pbbbbbbt.

What sounded like a loud, wet, raunchy raspberry reached his smooshed ears, and Discord held his breath, preparing for a stink bomb’s worth of repugnant assgas to invade his olfactory…

It didn’t come. Now that he thought about it, the noise sounded rather muffled—

Giggling.

Though he heard the noise through two fat globes of blubber, there was the unmistakable, lilting sound of giggling from up above.

Really, dear? he sent. All that for an innocent schoolyard prank? And you say I’m the one who needs to change his scales. You’ve more potentiality for chaos than you give yourself credit.

The wet-sounding raspberry was a literal one, he realized. Celestia had strung him along, planting her delicious rump on his face and casting a sound reproduction illusion spell to make her stomach sound like it was churning up an atomic gas bomb. The raspberry was produced by comparably mundane means—the type a mischievous older sister would blow on her sibling’s belly.

Not that Discord was going to chance another instant wedged against Celestia’s assgun. Summoning a thought, he popped out from under the princess’s rump and materialized in front of her as he sucked in lungfuls of air.

“My, Discord. Taking your leave so soon?”

Discord glared daggers at her.

“Really, Celestia? A fart joke? From the eternal symbol of grace and composure, you plant those apocalyptic buns on my face and pretend to unleash a torrent of flatulence against my poor nostrils?”

Discord made a pensive motion, pinching two clawed fingers against his chin. He envisioned himself in Celestia’s hoofshoes, touting around an ass that couldn’t fit through the door and partaking in an innocent night of mischievous, against the fellow deity with whom he shared a storied relationship, and he imagined giving her a taste of her own medicine in a delightful, juvenile fashion—

“Well played, my dear,” he said. “You’d certainly make it easier for your little ponies to follow their nose.”

Celestia rolled her eyes. “I was hoping you would know when to let a good joke end, Discord. I’d rather not carry that prank out of this room. In fact…” Celestia’s grin faded as she made a show of turning, her oversized asscheeks once again filling Discord’s vision as she gave her plump rump a hearty toss. “I’d say you’re owed a favor after that lowbrow prank of mine, hm?”

Discord smirked. There were distant second thoughts prodding at him, but he knew Celestia wouldn’t make a prank out of imitating the darker side of her rump’s secondary function, only to hit him with the genuine act while his guard was down. She was too regal, too uptight for that.

“You have always been a paragon of generosity, my dear.” His toothy smirk was positively greedy as he considered a no-strings attached session with Celestia’s rump. “And I’ve always been such a delightful gentleman. It’d hardly be fitting for me to turn down such a whale of a gift.”

He gazed at the fattened cheeks bouncing like a seismic event, serving his growing lust as he idly ran a clawed hand down his shaft, which was still standing proud, even after his harrowing experience with Celestia’s pucker. “Though, beggars  can’t be choosers, naturally. So tell me, Celestia. What do you have planned for that elephantine rump you’re waggling around?”

Celestia didn’t respond. She backed up slowly towards Discord, occasionally glancing back over her shoulder and giving him a flirty wink. Her bulging cheeks approached him like two fluffy pillows about to smother him in pleasure. Discord’s eyes were locked on the approaching object of his affection, grinning devilishly all the while.

Then, Celestia spoke. “You’ve been running around all night, Discord. Why, I don’t think you’ve had a moment to settle down and unwind. And you served your part well beneath these lovely gifts you blessed me with tonight. Why don’t you let your princess take care of you?”

Discord’s cock lurched in his hand, a series of shudders coursing down his spine. “That sounds delectable, Celestia. After all, your cheeks would make excellent sitters.”

Celestia rolled her eyes, then slammed her ample cheeks against Discord’s torso. Her cheeks rippled upon impact, and Discord stumbled backwards, the wind knocked out of him. His erection bobbed in front of him as Celestia’s cheeks loomed over him like two giant marshmallows, and his eyes widened in a brief rush of fear that he was about to be treated to repeat encounter with Celestia’s fearsome pucker.

Suddenly, Celestia lowered her rump, sandwiching Discord’s cock between the pillowy warmth of her magnificent, squishy buttcheeks. Discord’s form seized up, bracing himself against the carpet with his hands. “O-oh sweet you…” he sputtered out, instinctively thrusting between the titanic globes that hugged his cock. They were smooth—so smooth, and the feathery softness of her fur threatened to cut their session short.

“You know, I should follow through on that prank just for that horrid pun,” Celestia said. She lifted up her cheeks, smirking as she stared Discord dead in the eyes. Discord’s erection slid out of her cheeks, leaving just the head inside. She felt him twitch, saw his hands clenching again—

—and slammed her butt down again, drawing out a blissful sigh.

“But it’d be a travesty if I made you pass out. And it’s hardly fun if just one of us is having all the fun?”

Tight. Hot. Discord gritted his teeth, his mind swimming in the mind-shattering sensation of having his dick hotdogged by Celestia’s blubberous flanks. He imaged his generous length would be poking out the other end of any other mare’s rump—or even Celestia’s, when it wasn’t supersized, but Celestia’s cheeks had swollen to immense levels, and his cock was completely swallowed up by her supple, jiggling layers of fat and flesh. He imagined it was like fucking a cloud, and he grunted as he slammed his hips forward with a fleshy smack, Celestia’s immense mounds rippling like he was fucking a platter of jello.

Celestia let out a moan as she felt Discord's girth pushing against her oversized flanks. There was, naturally, only one response: she squeezed even tighter, her voluminous mounds folding in over one another and collapsing against Discord's throbbing cock. He let out a muffled grunt, his eyelashes fluttering as she teased his length.

"My, Celestia," he managed to murmur out, squeezing a generous pinch of her ass as she massaged his member between her exercise-ball-sized rump. "These flanks of yours certainly have a—er, heavenly touch. Are you entirely sure that they're not—urgh—certified masseurs?"

Celestia rolled her eyes, but allowed a smirk to flit across her face. For his part, Discord couldn't imagine feeling any better. The weight of Celestia's rear—by itself approximately the weight of a normal pony—over his crotch gave a pressure against his member that he'd never before felt. It was heavy, with a tightness that heaved up and down like the ministrations of his own claws, yet with a softness that pressed gently against the flare of his cock, enveloping it from all sides and rolling along his throbbing length with a skill and touch that most ponies could barely even dream of possessing.

He let out a happy sigh, putting his arms behind his head as Celestia worked her magic.

"Enjoying yourself?"

"Quite," he remarked. Celestia's rump seemed to cascade over his crotch—where once his mighty cock might have thundered between a smaller mare's cheeks, Celestia's managed to hold him in completely, pleasuring each and every inch.

He moaned, his eyes closing for a moment as her rump pressed against the sides of his cock a bit more firmly than before, flowing up his sides and slipping over his head before slamming right back down. He could feel Celestia's mass against his balls, which were churning with pent-up cum. He wanted this—more than anything right now, he wanted this.

His nose twitched. There was a feeling within him: not an unpleasant one at first, but one that grew more and more urgent by the second. It felt, Discord reflected, rather like a leg that's been left still for too long. There was a twitch, a flick—a need to move and jerk and act. What kind of god of chaos was he, he wondered, to allow a mare to act upon him, as if he were some force of stagnancy, waiting for others to do unto him without any action of his own? He grunted as Celestia squeezed his dick, coaxing a small stream of precum from the tip, which oozed down the folds of her voluminous rump. No, no, no, he decided. That simply wouldn't do.

"You're—urk—a lovely masseuse, Celestia," he said, biting his lip. "Truly unparalleled. But as much as I appreciate the thought—"

He snapped his fingers. In the blink of an eye, Celestia was up against the wall, her rump protruding from behind her as Discord squeezed her massive ass with both hands from behind. He smirked.

"—I'd much rather finish off on my own terms, don't you think?"

In the blink of an eye, his cock was back between her cheeks, it s throbbing length streaking her still wobbling globes of flesh with its warm, generous precum. Celestia moaned as Discord effectively hilted his member in her ass, its pointed head just barely brushing against the edges of her clit and sending a cascade of shivers down her heavy spine.

"Ooh," she murmured, shuddering. She licked her lips, feeling herself grow moister by the second. Her own marecum still dribbled down from the lips of her marehood, moistening the surface of Discord's cock even further. "Well," she said, a smile crossing her face, "let's see what you can do."

Dicsord didn't waste any time, thrusting into her immediately and without a moment's hesitation. In and out he drew, repeating each motion with a powerful thrust of his hips and, quite often, a smack of her generous rump. Each slap of his paw brought out new waves of flesh and flab across that powerful ass, and he had to bite down on his lip to keep from finishing early. That rippling against his cock of such weight and warmth was almost enough to make him cum all at once—but he had other things in mind.

He was careful not to look too mischievous—oh, to Tartarus with it. If Celestia had looked back right at that instant, she would have seen a grin of pure wickedness cross Discord's face, stretching from ear to ear in a gesture of pure, unadulterated, villainous lust.

She would have her dues. Oh, yes, Celestia would.

The smacking and slapping of flesh against flesh filled the spacious chamber, with Discord's grunts mixing in with Celestia's moans. He felt a warmth growing in his balls, a surging force that seemed the churn inside of their depths as he fucked Celestia's ass until sweat beaded on his forehead.

For her part, Celestia was no passive observer. As Discord's long, lithe legs coiled beneath her, his tail wrapping around her waist, she squeezed her rump around his cock, moving her ass up and down in the air until she was once more hotdogging the entirety of its length, twisting and turning the skin to heighten the pleasure.

And heighten it did. Discord's eyes nearly rolled back into his head—and then, being Discord, he allowed them to roll back even further until they were spinning like lottery machines, rotating and vibrating in time with the rhythm of his cock against Celestia's massive, hanging rump. The pressure in his balls was building, pushing upward against the base of his cock until it was all that he felt, until he could hold it back no longer—

His eyes stopped swirling with a high-pitched ding!

There it was. Discord felt it coming on already: a base, animalistic need to want, to fuck. To spread his seed deep into a mare's virile womb and to—

His smirk deepened. But the god of Chaos was above such simple desires. He had in mind something...more.

"Oh, Celestia," he called, cupping one claw around his mouth as he smacked her ass with the other.  His smile betrayed a certain form of geniality—if one looked at it a certain way—but Discord had been thorolughly seized by his own mischievous spirit. "I've been thinking," he grunted out, thrusting once again between Celestia's titanic asscheeks as he gave them another full-armed smack. "Perhaps we can make this end a little more...explosively."

"Oh?" she asked from over her shoulder, biting her lower lip as her globular ass jiggled with each thrust. "Surprise me."

Discord's grin blossomed into a fully evil smirk. "I'm sure I will," he sang out.

He raised his claw to the light—

—and snapped his fingers.

Instantly, chaos magic surged at his fingertips—but it didn't stay there for long. Instead, he channelled it downward, through his chest, into his loins, and finally into his crotch. His already-oversized package throbbed even harder, its full veins pushing against their sides as they began to swell fuller and wider, his entire cock growing with each thrum of magic he let pumped into it.

His balls were affected too—as his cock passed fifteen inches in length, with the tip just barely poking out from the top of Celestia's ass and its base just above the middle—his balls had swelled until they hung heavily in between his legs, even pushing apart his thighs with their sheer volume. Each swaying motion sent the ocean of cum within each swirling and swishing about, which only served to further increase his lust and need to spill his seed.

Except he wouldn't just spill it anyhwere.

"Eungh," he grunted again, and gave her ass a particularly hard squeeze. Celestia giggled like a schoolfilly, thrust her rump in the air, and began to look over her shoulder—

—only to find two feet of throbbing draconequus meat and a pair of comically oversized balls staring her in the face.

Discord's fang poked over his lower lip as his smirk deepend. "Surprise."

With that final remark, Discord came like a tsunami.

The orgasm hit him like a bolt of lightning. He could feel his spine tingling with electricity, his hips thrusting up and into and over Celestia's rump, his now-massive shaft poking up far above Celestia's ass until it was aimed like a pressure cannon directly at her face. He felt the first load of his seed surge through his length, pushing through his knot and up into the head where it was ready to spill forth into the warm air.

Splat. A thick glob of Discord's seed landed directly over Celestia's eye, sticking to her face before beginning to ooze down her cheek.

Splat. Another followed soon after, this one striking her directly on the chin. Discord felt his hips go back with the force of this one; appropriately, Celestia's head actually whipped back a few centimeters as the mass of spooge hit her face. It fell down her neck, and then her shoulders until it was running in dozens of thick, white streams down to the floor below.

Splat. Splat. Discord shifted his aim ever so slightly, leaving Celestia's head a dripping mass covered with his seed. His new target: her wings. Thick globs of his cum were pumped out with each jolt that ran down his spine toward his balls, his cock pulsating with each new spurt. His cum was like a flood, covering Celestia in its pure volume.

Soon enough, her wings were so thick and sticky with his seed that it was nearly impossible to believe that she'd be able to move them without a several-hour-long bath. Discord's eyes narrowed—Celestia's still wide, and in complete shock—and he shifted his aim to his final target.

Even more, thicker globs of cum came spurting out of his tip, flying up in the air before they came right back down to land on Celestia's spectacular ass. Some didn't even make it—they stuck to the ceiling, or missed entirely, plastering the walls or drapes before slowly dripping back down to the floor—but a certain amount managed to get its trajectory just right before splattering back down on Celestia's rump.

On and on, Discord came, his massive balls churning out enough cum to fill a pony up twice over. Each cheek closing around his member was now thoroughly white: each of Celestia's Cutie Marks, even swollen to their current massive size, had been drowned beneath his virile, warm seed.

His member heaving, Discord felt the orgasm subside, his balls emptying of their heavy load. Panting, he let the sensation fade, that overpowering desire slowly falling until he was able to remove his cock from Celestia's massive, cum-stained rump with a thick, wet-sounding schlup!

Celestia collapsed like a marionette who had its strings cut. Her lungs attempted to suck in greedy breaths of musk-stained air, and she sputtered as globs of Discord’s jizz dripped into her mouth. She swallowed the traces of his load like a seasoned professional, then licked her lips and gathered up another helping of semen, sending that batch down her throat as well.

She still felt dollops of cum dripping down her face. Through her ragged pants, she lit her horn and magicked over a body-length mirror to survey the titanic load that had just been dumped upon her pristine figure like a tank of slime.

Celestia’s eyes widened at her besmirched reflection, her eyelashes sending a dollop of spooge airborne.

She was absolutely plastered. Her face was drenched in sperm, as if several stallions had made a sperm bucket of her beatific visage. A dollop of cum dangled from her horn like a thick strand of saliva, and her wings felt heavy and sticky, like she had just climbed out of a pool of molasses.

And her rump… she didn’t need a mirror to feel the gooey, clinging warmth of a barrel-load of jizz dripping down her swollen buttcheeks.

“Unf.”

The utterance slipped out  on its own volition. She had no say in the matter.

There was no response. A quick glance at the mirror revealed that Discord—partially obscured by her titanic buttcheeks, but still visible—was put out, the draconequus king crashing like a junkie high on chaos. His enhanced cock was starting to taper, limping off to the side and poking at the floor.

How ridiculous do we look?

Celestia allowed herself a serene smile as her backwards glance fell upon her fattened cheeks, giggling as she gave them a light shake, feeling the immense heft of her derriere jiggle like a seismic event. Her knees quivered, but otherwise held sturdy.

Well… this was just one night, wasn’t it? And, truth be told, she did harbor a secret adoration for her gracious rump—even if it implied an eating habit unbefitting of royalty.

Her eyes surveyed the room. There wasn’t extensive evidence to suggest that two immortal demigods has indulged in an act of depravity that would make even the most gutter-minded of ponies blush. The posh quarters retained their summary regality—her fluffy feather bed, the one wall shelved with antique tomes…

...Why, if one ignored the puddle of marecum beneath her and the gooey strands of semen dripping from the tapestry—

Splat.

Celestia’s face twisted in a grimace as a warm dollop of freshly-deposited spooge dripped down onto her nose. Rolling her eyes, she glanced back at Discord, her suitor still on another world.

Tomorrow would be another day. She would hold court, dabbling in the affairs of her precious little ponies as she perched on her throne, flanked by two guards who stood imposingly like immortal guardians. She’d handle the daily affairs of the castle, enjoying life’s simple pleasures while she upheld her status as Equestria’s benevolent and shining beacon. A life that she cherished, and wouldn’t trade for anything.

Splat.

But tonight… it didn’t come along often, did it?

And behind her was a lusty draconequus who enjoyed dabbling in the carnal pleasures when the time came along. Nothing too unreasonable. All things in moderation.

The night was still fresh, but the seconds will dripping away like the gallons of cum dribbling down her regal coat.

Smirking, the princess of the sun stood up, and began to walk ass-backwards towards her bestower.

“My, Discord. Your penchant for making a lasting impression never ceases to surprise me.”

Discord offered a toothy grin, and his mouth was about to open in a no-doubt naughty rebuke—

Schlup

—his muzzle slipped between Celestia’s cum-splattered buttcheeks. The princess giggled as she glanced backwards, Discord’s eyes widening in shock as his face was slathered in his seed.

“Then, perhaps you wouldn’t mind if I leave an impression of my own?I think it’s a perspective you’re well acquainted with.”

Smoosh.

That’s when Celestia dropped her cheeks, pinning Discord’s head to the ground, trapping his head wholesome between her rump.

“Mmmpphh!”

Celestia giggled, feeling her cheeks vibrate as Discord protested from within his fleshy prison.

“Why don’t you savor it, then? This is your work, afterall.”

A few gyrating motions of her swollen hips came next as she ground her deep crack along Discord’s muzzle. A smile flitted across her face; beneath her, she could swear that she’d felt Discord stop squirming, instead chuckling in agreement.

She looked around the room—her upturned, cum-flooded room—and threw her head back and laughed.

“And after all, this night only comes once a year.”
