Celestia and Twilight are fat blobs tormented by Nightmare Moon.

Years after the defeat of Princess Celestia, the moon shines eternal over Equestria, bringing a cold light to even colder snow. Food is scarce, society nonexistent; All that remains is the cruel and beneficent regime of Nightmare Moon.

For the citizens, as the last food runs out and the clouds usher in an endless winter, the nightmare is almost over. But for Celestia and Twilight, trapped with the prison of their own impossibly obese bodies, the nightmare will never end. For Nightmare Moon owns them, and they must suffer.

Contains: Fat, immobility, extreme slob, rape, hard vore, extreme sexual violence, cum inflation, death by bursting (and other methods), cock vore, cock transformation, and a bad end for the entire planet.

A commission for ggg333 on Furaffinity.

The Only Chapter

Snow was falling in Canterlot. Until recently the seat of Celestia's royal power, the city stood in shambles; Ruined buildings lined the streets, craters and scorch marks still marred the magnificent roadways, whose golden cobblestones had long-since been pried up by scavengers. Now covered in a layer of ice, the city gleamed in the moonlight, a shallow parody of the citadel it once was.

Bedraggled ponies hauled their decrepit carcasses through ankle-deep snow, dreaming of a summer that would never come. The moon gave no indication of the passage of time, hanging full and proud in the center of the sky, as it had through the long years since the last sunset.

Most of the citizens were dead, either from the war, starvation, or the omnipresent cold, their bodies forcibly seized by the Night Guard for purposes unknown. Smart money was on some kind of necromantic ritual, an attempt at creating some sort of undead army to conquer those lands who yet defied the power of the Nightmare. Those who defied, and tried to hide or bury their dead relatives were met with summary execution, only adding to the ranks of the ever-growing corpse-army, or whatever horrific fate awaited them behind the rusted gates of Canterlot Palace.

Two corpses lay in the street, blood still oozing from ragged wounds in their throats, steaming in the frigid air. If any of the scattered ponies cared, they didn't let it show; Anything like that could be considered resistance, and grounds for execution. These two ponies, a pair of mares, were lucky, as their fate had been swift compared to the prolonged deaths concocted by the Royal Torturer.

Their crimes didn't matter. Everything they had, everything they were, was loaded into a cart by a stallion dressed in black robes, the crescent seal of the Nightmare emblazoned on his hood. Licking his lips, he climbed aboard and tapped the driver on the shoulder, signaling her to begin the ascent toward the palace.

Compared to the rest of the city, the palace was almost intact; Nightmare Moon wanted her prize, after all. The bulk of the damage lay in the outer defenses, where a few loyal guardsmen fought to the last man against the brainwashed population of the city. Mares, stallions and foals, all arming themselves with whatever they could find and marching on the palace, slaughtering the defenders like lambs... Of course, as soon as the brainwashing wore off and the ponies realized what they'd done, most chose to slit their throats in grief. The few who didn't, became the nucleus of the new Night Guard.

The carriage flew over the outer wall, then through a gap in the palace itself, where magic-melted marble created an entrance for the endlessly driving snow. The tapestries had been burned, the stained glass smashed and used to slit the throats of the artisans who had refused to make replacements honoring the glory of Her Nocturnal Majesty. Now, the walls were decorated in a more tactful and less vain manner – With the skulls of those who dared defy their rightful ruler.

The carriage slowed to a walking pace as it entered the hallway, the wheels leaving very little room amid the tight corridor. Why they didn't just blow a hole in the wall of the throne room was a question for brighter and more inquisitive minds than theirs; Some useless mud pony lay in the hall, bleeding profusely from a large gash in it's side. The guardsmen simply walked over him, listening to the satisfying crunch as his neck snapped beneath the heavy wheel of the carriage.

Even from the other side of the palace, strange noises were heard, whiffs of horrific smells wafting past the noses of the Nightmare's loyal servants. As they drew nearer, the air became darker, thick with a brownish miasma through which the moon's dim light seemed almost nonexistant, forcing the use of magelights wherever the oily air hung. The throne room doors were missing, with massive gouges in the wall showing where they had been ripped from their hinges by some immense force.

The room was hot, so much so that it reminded the guards of the days before the Nightmare, back when heat came not only from a pathetic fire in the corner of the room, huddled around by half a dozen starving ponies, but from the very sky itself, where now hung only the cold moon and distant stars. This heat wasn't accompanied by the warm smells of a summer day, but the hellish humidity and odor of a swamp, the source of which they discovered as they trotted through the doors.

Two vast, shapeless blobs occupied the chamber, one covered in purple fur, the other, a brownish-green color with occasionally lighter patches, suggesting that it may have once been a brilliant white. The brown one was the larger of the two, it's bulk spreading across slightly more than half the room, easily the size of a small house in itself.

The purple one wasn't quite as big, only the size of a trailer instead of a full-sized home, taking up only a quarter or so of the remaining space. The rear end of the mound, or at least, the part facing away from the chamber door, was marked with the image of a star, stretched thin over the immense canvas. A low gurgling noise emanated from deep within the blob, followed by a blast of rank air that only added to the toxic atmosphere.

The two night guards donned gas masks, but even so, their breathing grew more laboured, their movements quicker as they tried to complete their task before the poisonous air took hold in their lungs. To tarry here was to invite a fate worse than death, or so the rumors claimed, with stories of mutation and dissolution passing through the mess hall whenever Her Majesty deigned not to attend... Which was most of the time, as her appetite was such as to make the rest of her subjects lose theirs.

Approaching the purple blimp, the cart slowed, then stopped. The creature's face was hidden away in a small crack, barely noticeable to the untrained eye, but the experienced guards knew just where to look. Hopping down from the cart, the unicorn's horn ignited, peeling back a layer of flab to reveal the bloated, ruined face of Twilight Sparkle.

She had never been a supermodel, but with several tons of unwashed lard piled onto her body, she looked downright repulsive; Her cheeks were as big as watermelons, covered in blisters from constantly rubbing against the ring of neck flab that encircled her head like a spare tire, nearly hiding her face within it's sagging mass.

Even her eyelids were fat, covered in a layer of lard that made it impossible for her to see, not that there was anything to see, aside from the other blob she shared the chamber with. In a haze of pink magic, the unicorn forced the blob's eyes open, the unfocused purple retinas dilating in the dim light. Twilight's jaw trembled, a wet gurgling nose rising from her throat; Listening carefully, the unicorn was just barely able to make out the words above the constant churning of her stomach.

“Shiny?”

The unicorn chuckled, throwing back his hood to reveal a mane of close-cropped blue hair. His face was a mass of scar tissue, with more raw pink and half-healed black scrapes than actual fur or flesh, but the outline of Shining Armor's face was unmistakable. The stallion laughed, his voice cold and cruel as he stared into his blobbish sister's dull eyes.

“Feeding time, pig,” He said, thrusting a hoof into her chin blubber, which sunk nearly to his knee before he withdrew.

Turning back to the cart, he nodded at his comrade, and the two hefted the corpse, now stiff from cold and the onset of rigor mortis, and tossed it on the floor before the blob. Twilight stared down at it, eyes wide and starving; Her horror at such things had faded long ago, leaving nothing but the hunger that permeated every moment of every day of her new life.

“Nobles, I think,” The stallion chuckled, “Looking mighty skinny, after Lady Nightmare had those secret farmsteads destroyed. Some ponies need to learn to accept their new diet, right sis?”

Twilight only groaned, her enormous stomach twisting and letting out a sickening noise. She had once detested meat, feared and disliked those creatures whose digestive tracts were geared toward the stuff, but now, with a body built of Canterlot's citizens, she found herself enjoying it. The crunch of the bones, the popping of organs between her teeth... It was like a kind of candy, candy that sometimes fought back if it wasn't quite dead yet,

A useless struggle, once their bodies were lodged between Twilight's ravenous jaws, enhanced by the Nightmare's magic to crush through solid diamond with the same power as her former assistant's draconic jaw. Her mouth watered, saliva oozing from the corners of her lips and down her myriad chin folds, joining the puddle of stagnant sweat and bodily fluids that hung around her body.

“Not just yet, Twily,” Shining prodded his sister's flab chastisingly, “We've got to process them first, haven't we? Cady, are you ready?”

The pegasus stepped forward, flipping back her hood to reveal Princess Cadence's legendary face. Her famous pink mane was cropped close to her scalp, making no effort to hide the shattered stump of a horn. Every few seconds, a faint blue glow would form in the ruined organ, and Cadence winced as a searing bolt of pain shot through her skull.

“As always,” Her voice was low and scratchy, barely audible; Across her throat was a thin scar, barely perceptible beneath the fur.

“Then go ahead and cast your spell.”

Cadence's face took on a look of absolute concentration, her teeth clenching and eyes squeezing shut. The ragged stump of her horn began to glow, and then, with a loud pop, a burst of magic shot out, accompanied by a scream from the poor mare as she staggered back. Blood leaked from her nose, and judging by the twin red trails in her fur, this wasn't an uncommon outcome.

Shining paid his wife's suffering no mind, turning his attention to the two corpses. For a moment, the bodies seemed to wobble in place; Then, with a faint hissing sound, they appeared to deflate, their heads flattening as their skulls disappeared, torsos losing shape and melting into a gelatinous mass of flesh... One of them, Shining noticed, twitched slightly as the keratin of her hooves turned to vapor; He sincerely hoped there was enough life left within her to feel the pain of her skeleton dissolving.

“There we go, sis. Lady Nightmare would be displeased if her favorite fucktoy choked to death on something that isn't her cock.”

Shining's horn ignited, and Twilight let out a gurgle of excitement as the first of the flabby corpses hovered toward her mouth. Her jaws were lined with pointed yellow teeth, nearly as big as a dragon's fangs, but much sharper. As soon as the dead body was close enough, she craned her head out and took a chomp out of the head, which stretched and split from the rest of the body like toffee.

The mountainous mare chewed noisily, chunks of flesh and splashes of blood oozing down her many chins. Farts trumpeted from her ass, powerful enough to shake the palace, and wake the white blob next to her.

“W-whub?” The voice was barely audible over Twilight's cannibal feast, but Shining's sensitive ears could never mistake it. Stepping over the incapacitated body of his wife, he trotted around the mound until he reached a massive divot, like a belly button big enough to hide a foal inside. Peeling back the flab revealed, not a foal, but the once-beautiful face of Princess Celestia.

Even in her horrifically obese state, forcibly separated from the sun and everything she'd ever cared for, she still looked absolutely radiant, at least in Shining's opinion; Then again, he did have rather strange taste in women, or so a former subordinate once said. He agreed, but that didn't stop him from stabbing that subordinate to death with his own severed penis.

“Morning, shitblimp,” Shining said in a gentle, motherly tone, mimicking the princess's famously coy smile, “Are you hungry too?”

At the stallion's words, Celestia's eyes darted toward her former student; She couldn't see more than a quarter of her student's gut, but the sounds of eating were unmistakable, as were the growls of hunger from the white blob's own stomach. Unlike Twilight, however, her teacher's face was queasy, a faint green color visible through the mass of bedsores and acne that made up her globular cheeks.

“P-pweash, no,” She mumbled, her thick lips and flab-choked vocal cords making speech almost impossible, “Gill mweh.”

Shining only chuckled, glancing over at Cadence, who was just stirring from her agonized blackout. Turning back to Celestia, he leaned in and planted a kiss on her filth-encrusted lips, which the mare was helpless to avoid. His cock was throbbing, almost as much as when he fed his sister, or when he killed those worthless peons earlier; There was nothing he wanted to do more than to penetrate this useless blob's eye socket with his rod, but no matter how hard he tried, his limbs refused to respond to any such function; An effect of the geas Nightmare had placed on him, forcing him to obey none but her own will. Part of that will was that Celestia and Twilight were to remain unharmed, despite the desires of his demented brain.

A pimple burst beneath Shining's lips, and his tongue lapped up the foul pus. It was good, almost as good as sucking on a broodmother's swollen and disease-filled crotchtits, but all good things must come to an end, and by the time he finished sucking, her lips appeared only their size; Shining chuckled at the implication of that, then moved back, casting a glance at his sister's feast.

Somehow, Twilight had managed to lodge the corpse in her mouth, and was slowly munching her way down the torso, drawing it further into her mouth with nothing but the power of her own jaws. One leg hung on by nothing more than a thread, and with a chomp, it fell, hitting the floor with a damp splat. With wobbly legs, Cadence walked over and picked up the lost limb, pressing the end gently against Twilight's massive gnashers. Within seconds, it was torn from her hooves with the power of a raging dragon, nearly sending her own hooves into the industrial furnace that was Twilight's mouth.

The other corpse still lay on the floor, appearing slightly more melted than the other one; The extra time had allowed the spell to dissolve the musculature as well, leaving behind nothing but flesh and flab. Levitating it, he flipped the dead mare around for a quick glance at her pussy; Loose and bloody. She'd probably been prostituting herself for food, something Shining had partaken in many times, whenever the Royal Torturer ran out of ponies for him to skullfuck. A single scrap of meat for a fuck... Now that was good business.

“It's time,” Shining hissed, holding the disjointed face close for Celestia to see, “Remember this one?”

“Fuh-Fleur,” She finally gasped out, a tone of defeated misery in her voice. She'd done this routine every day for years, and it never got any easier looking at the faces of her former subjects; When she was lucky, they were dead, or at least too far gone to scream as their loving goddess was forced to devour them. With the falling temperatures and dwindling food supply, she'd been getting lucky more often than not.

Smirking, he levitated the former model's face toward the princess, who recoiled as much as was possible with a solid wall of flab holding her back. Her eyes screwed shut, her mouth buttoning as tightly as she could, but with a magical yank, her jaw stretched wide, revealing multiple rows of teeth just as long and jagged as Twilight's chompers. Tears formed in the corners of her eyes as Shining slipped the dead mare's head in, then forced her jaw shut with such force that her teeth clacked together.

Defeated, Celestia began chewing her meal, retching every few minutes, but managed to get most of Fleur's torso down before the inevitable meat-slurry came up, spraying the floor in stomach juice and chunks of undigested meat. Across the room, Twilight let out a belch powerful enough to send Cadence flying, hitting the far wall with a solid thud.

“Don't die on me, Can't Dance,” A deep, sultry voice called from the doorway. Cadence's groan cut off, and Shining slowly turned his head, a mixture of dread and excitement pulsing in his throat as he behind the glory of Nightmare Moon, Lady of the Dark and Rightful Queen of Equestria.

Twelve feet tall, as sleek and slender as Celestia's ruined body once was, she glided through the shattered doorway with all the grace and dread of a silent movie monster. Her eyes were slits set against orbs of blood red, her mane and tailed billowing behind her as she daintily stepped over Cadence's crumpled form and over to the mountain formerly known as Twilight Sparkle.

“Greetings, unicorn,” She chuckled, looking into the mindless mare's dull eyes. Twilight's only response was to open her mouth and let out another belch, splattering the demon-queen's face with splotches of blood and hair. Her eye twitched, lips curling back to reveal her own razor-sharp teeth, and for a moment Shining thought she was about to kill the poor wretch – He'd miss feeding the useless blimp, but then again, stuffing her remains down Celestia's throat would be just as much fun – But no, Nightmare Moon just laughed, reaching down and grabbing a chunk of meat that'd missed Twilight's mouth.

“M-Mistress Moon!” Cadence rose shakily, staggering over and nearly collapsing as she bowed to her rightful sovereign, “To what do we owe the honor of your presence?”

“Oh, I just thought I'd pay a visit to my dearest elder sister-”

“Damn her! Damned be her name!” Cadence shouted, rising before remembering herself and collapsing once more.

“Yes, yes,” Nightmare Moon turned from the pathetic mare, her tail whipping against her face, leaving a reddish welt despite the ethereal nature of the thing.

“Tia!” Her voice was suddenly jovial as she trotted up to the white mountain, kicking aside the flabby, boneless corpse of the model, “How's my dear sister doing today? Are my guards feeding you alright?” She pressed a hoof into the ring of flab around Celestia's neck, which sunk almost up to the knee before she pulled it away, “Would you like to suckle your darling younger sister's cock?”

“Momsher,” Celestia tried to spit, but her blubbery lips muted the force, and all that came out was a wave of bloody drool. After a moment, she tried to speak again, “You defroy'g Egweshdr'a.”

“Au contrare!” Nightmare took a step back, laying a hoof upon her chest as if offended, “I've improved this land immensely! For example, your scrawny body. What were they feeding you, Tia?” The use of the old nickname only infuriated her sister even more, “By sacrificing my useless subjects, your body is sustained and improved day by day! Can you even remember the last time you saw your hooves?”

Nightmare glanced around the side of the blob, where a small divot indicated where Celestia's hooves were entombed. Leaning in to her sister's face, she smiled, planting a small kiss on the blob's pimple-spotted cheek. Celestia closed her eyes, trying as hard as possible to cast herself back in time, to pretend they were just a couple of sisters again... But her gut twisted, and she gasped in pain as a greasy fart splattered forth from her immense ass.

“Such divine wind,” Nightmare cooed, her voice so sweet and gentle that it unnerved even Shining Armor's unshakable heart, “I love your new perfume, sister.”

Nightmare's hooves were once again upon her sister's neck-flab, sinking so deep that their noses were mere inches apart. The lunar tyrant's horn ignited, and Celestia felt a tingling sensation in her mouth. Though she couldn't see, she could guess what was happening – Her teeth were shrinking away, dissolving into the aether, or more likely, being teleported inside some poor wretch's liver. Either way, she knew precisely what was coming.

“I've brought a gift, Tia,” She said gently, slipping her hoof between Celestia's sausage-like lips and prodding her soft gums, “Can you guess what it is?”

“I know!” Suddenly, Cadence got up and lunged toward Nightmare Moon, closing the distance in an instant. Before Shining could stop her, she clambered between the demon-queen's legs and beheld the monster that dwelt between her legs. Her package was enormous, her nuts each the size of a pony's head, her cock bigger than most stallions, even in the sheath... Drool leaked from the corner of the former princess's mouth as Nightmare's musk wafted past her nose, strong and rank enough to overpower the stench of the twin blobs. Gods, it was even more powerful than most stallions-!

She couldn't restrain herself from burying her face in her ruler's sheath, pressing her snout as far between the meaty folds as possible. The sheer masculine stench was incredible, coming from such a pinnacle of femininity; Clearly, Her Infernal Highness had taken it upon herself to achieve perfection in both sexes, rather than constraining herself as lesser mares once did.

Luna had always been reluctant to shower, as most younger siblings are, and that trait was only amplified after succumbing to evil. Her stench was almost as infernal as her actions, a constant miasma of feminine and masculine aromas swirling through the air around her, polluting the noses and brains of those unfortunate enough to be near her.

Traces of sweat and smegma smeared across Cadence's face as she pressed further in, searching for the tip of her ruler's glorious dong, but even as she craned her neck, desperately shoving her head further in, her exploring tongue couldn't seem to find it. Her ears, nearly engulfed in the soft flesh, caught Nightmare Moon's muffled laughter, followed by a swift kick to the gut that sent her sprawling across the floor.

“My glorious cock isn't for you, little mare,” She spoke the last two words with unconcealed malice, the same tone she'd used when informing Blueblood he was to be gelded and sent as a gift to the Dragonlord. Cadence quivered as Nightmare placed a hoof on her stomach, just above the crooked scar where her ovaries once were, “But in this case, I'll make an exception.”

Her horn glowed, a black cloud of magic engulfing Cadence's entire body, from the snapped end of her horn to the close-cropped stump of her tail. For his part, Shining was stationary, eyes straight ahead as years of training had taught; If he felt anything at his wife's fate, he certainly didn't show it; Indeed, the erection throbbing between his legs remained as firm as ever.

Cadence let out a shriek, echoing across the walls of the chamber and out into the snow-stilled ruins beyond. Her hooves wiggled uselessly, as if she were attempting to deny her queen's blessing, but it was no use. Her outline became fuzzy, indistinct, and as she struggled, little blobs of matter broke away from her flailing hooves, floating through the sea of dark energy like wax in a lava lamp.

Her screams became louder and less articulate, words melting together as she pleaded for an end to the unbearable agony she was doubtless feeling; Her limbs were nearly gone, mere stumps, while the outline of her bones became more and more visible through the murky magic. The silhouette of her skull became visible, and her screaming devolved into gurgling, before dying away entirely.

Nightmare's horn went out with a hiss, and Cadence's remains splattered to the floor. All that was left of the poor mare was a puddle of white fluid, thick as molasses as it oozed across the floor. A few mulchy bones stuck out of it, a tibia here, the faintest hint of a jawbone there, but even these soon disappeared, melting into slime. The stench was enormous, almost enough to overpower the twin blobs. Shining nearly gasped as he recognized it, the smell of what his now ex-wife had become-

“Semen,” Nightmare finished his thought, a smile curling across her thin lips, “A puddle of rancid foal-juice, still alive and ready to impregnate.”

Nightmare's horn glowed once more, and the puddle of sperm floated into the air. The demon-mare's cock slid from it's sheath, going from flaccid to erect in mere moments, gaining inch after inch of length and girth. By the time it finished growing, it was almost as long as one of Nightmare's massive legs, and just about as thick, with the tip nearly reaching between her forelegs.

The cloud of sperm quivered in the air for a moment, as if whatever was left of Cadence was afraid. Then, Nightmare's cocktip flared, and the sperm flowed down her shaft, her urethra bloating visibly as gallon after gallon of mulched-up pony slipped down and into her meaty sack. It was already beginning to bloat, the smooth surface growing tight, veins popping out, warts and bumps forming as so much dark energy filled her foalbags.

Shining stared at the massive orbs, churning with the remains of his wife. He almost felt bad – Then, he remembered how absolutely bucking annoying she was, even before Nightmare Moon cracked her horn and turned her mind to mist. He chuckled softly to himself, watching as her nuts jostled and sloshed as the last dregs of Cadence's useless DNA were boiled away, replaced with the purest black magic.

“Armor,” Nightmare snapped, “Do you wish to join your wife?

Shining snapped to attention, the chuckle dying in his throat. A bead of sweat formed on his forehead as Nightmare Moon walked over, her nuts sloshing as they rocked from side to side... He stifled a groan as his own cock throbbed. He couldn't show emotion. No, he was stoic, he was stolid, he was a statue... A cold hoof poked his cock, and a little dab of pre spurted across the floor.

“You've contributed to my glorious scepter, haven't you?” Nightmare asked, cupping his minuscule ballsack.

“Y-yes, your Infernal Majesty,” He stammered, his voice cracking slightly as he remembered his former length. Every male in Canterlot had contributed, some much more than others. He counted himself lucky to have escaped with enough to satisfy a mare... Or at least, enough to satisfy himself.

“Take care that you don't contribute more.”

Nightmare Moon's long, slender horn ignited, and a tingling sensation spread across Shining's body. His heart began pounding, and he let out an involuntary squeal of panic as he felt the floor disappear beneath his hooves. The magical aura flipped him around, putting him face to face with his ruler's groin. He tried to speak, but his jaw was held tight by the magic, and all he could do was groan in fright as he floated closer and closer to Nightmare's massive rod.

By Nyarlathotep's mane... After so many years, he'd almost forgotten what a real cock looked like, and the sight of Nightmare's monster was enough to send his little prick into new heights of hardness. A baseball-sized ball of precum oozed from Nightmare's cockslit, while a mere bead of milky fluid dripped from his own. A moan slipped out, which the black mare must've heard, as she gave him a pat on the back that seemed almost gentle, like a mother comforting an upset foal.

“Don't fear, my loyal servant, for you are about to become part of something much greater than yourself.”

He knew – Oh, by the demons of the pit, he knew, and despite his outward reluctance, deep down, he couldn't wait. Sadness for his wife and panic at his own fate competed with the rising tide of lust, pulsing through his body like waves of electrical current. Whether it was his own will, or some effect of Nightmare Moon's magic, it was impossible to say, but as he moved closer, catching a whiff of musk, he found himself eagerly awaiting the moment his lips would touch her throbbing member.

His mouth began to tingle, and suddenly, he felt his teeth slipping away from one another, receding into his gums. No more ravenous feasts of pegasus wings for him – There was another food, sweeter and more subtle, which he would dine on until the end of eternity itself. The tip of her cock flared up, and his mouth stretched wide to match, nearly popping his jaw from the socket. Even with these precautions, Nightmare's cockhead barely slipped between his lips, squeezing into his soft gums.

A myriad of flavors flooded the stallion's mouth; Salty cum, a hint of bubblegum that may have been the remains of his wife's perfume, and most of all, the overpowering stench of Nightmare's musk. He didn't realize just how slick the thing was, coated in sweat and more than a little cum, until his tongue was sliding across the surface, collecting slime like a cock in a candy store. He moaned, eyes rolling back in his head; His chest felt tight as he snorted up lungfuls of musky air, his tongue delighting in the myriad of masculine flavors.

Shining retched as Nightmare's cock prodded the back of his throat, a glob of hot stomach juices rising to meet her as she slowly worked her way down. She let out a grunt as Shining's jaws squeezed involuntarily, his gums squishing uselessly against the sheer mass of her beastly marecock. His throat bulged out to accommodate it, every rib and vein outlined in his thin flesh.

His eyes grew blurry, but he could see Nightmare's sheath rising to meet him as inch after inch disappeared down his gullet, until finally, his nose bumped against her soft, fuzzy cockpocket. At the same time, deep inside of him, he felt something he'd never felt before – Nightmare Moon's cockhead bumping against the opening to his stomach. He groaned as she withdrew her cock slightly, then rammed it, breaking through the gate with a slight pop.

Nightmare Moon sighed, stretching back up to her full height. Shining wiggled slightly as she moved, but with her erection lodged so deep in his belly, he couldn't escape if he wanted to. Though he couldn't taste the precum now oozing directly into his stomach, he could feel it, little globs like chunks of lead plopping one by one into his stomach. And to think, he was going to be a part of it-!

He could already feel it, a sort of abrasiveness between his esophagus and the surface of her cock, but it was more than friction holding them together. A burning sensation grew in his stomach, spreading up his throat as his flesh began to break down, cells bursting apart and recombining on the molecular level. At the same time, Nightmare shuffled uncomfortably as her own cock did the same, dissolving and melding together with the stallion's body. A burning sensation spread throughout Shining's body as the demon-mare's blood began pumping through his body, just as his own heart stopped beating.

Shining let out a fart, blasting out every last drop of gas in his body. With his intestines melting together in the shape of a fat cumpipe, there was no more use for such things. He was becoming a part of something greater, and while a little voice nagged at him to resist, the rest of his brainwashed and perverted mind was wholly focused on the sheer joy of becoming one with his rightful queen.

His cock twitched, shooting out a rope of cum far larger than anything his little nads could've produced. The flow continued, thick as snot, sending shivers up his and Nightmare Moon's spine as it pooled across the floor. At this point, his head was beginning to meld, his nose slowly disappearing into the firm flesh of her cock. The fur across his body was beginning to recede, fading into the black flesh. Even his limbs were shortening, muscles withering as every last bit of biomass was converted to pure sexual meat.

His anus bloated out, turning into a thick donut just in time for a blob of cum to ooze out, slipping down his taint and clinging to his balls, which were swiftly fading into just another pair of cockbumps. It was already becoming hard to tell where the stallion stopped and Nightmare's cock began, and as his limbs slowly sunk away, it became nearly impossible.

His nose melted away, and his eyes followed suit. The last thing he saw was a drop of sweat oozing through the tuft of fur at the base of Nightmare Moon's sheath, slowly oozing toward the bump where his nose once was. Though he could no longer see, he could feel it – He could feel everything, every nerve in his body melding with those of the tyrant, sending an overwhelming array of signals to the mushy remains of his brain, which were themselves melting away into mere cockflesh.

Her new cock throbbed beneath her, a muffled gurgling sound emanating from somewhere within as Shining's near-nonexistant tongue mumbled something. Some shred of the stallion's mind was still holding on, but she wasn't going to wait until he fully melded; Nightmare turned to her sister with a grin spread across her face, revealing rows of slender, razor-sharp fangs.

A grumble emanated from deep within the Twilight's cavernous belly, and a smile spread across the demon's face as she turned towards her. Twilight smiled too, the corners of her lips digging into her head-sized cheeks. Her unfocused eyes glanced across the room, sometimes in tandem, sometimes independent, but never truly seeing anything. At least, anything aside from food.

A happy gurgle rose from Twilight's throat, saliva dripping from one corner of her slack jaw as she stared at the demon-mare's cock, which still bore a vague resemblance to her brother's body, but she didn't care – All she could see was the steady stream of pinkish cum leaking from the tip.

A pit of worry rose in Celestia's stomach – Her finest student's brain was too damaged to comprehend the incredible danger she was in. She tried to shout, but the incredible amount of lard pressing on her throat stifled her voice, and the rest was muffled by her blubbery lips. There was nothing she could do but watch as Nightmare drew closer, gently teasing the unicorn's jaw open to it's fullest extent, then slipping the tip of her cock in.

Twilight's jaw snapped shut, and Nightmare winced as her jagged teeth bumped against the flesh of her cock, unable to pierce the iron-like flesh, but certainly sending a thrill of panic up the former mare's spine. Celestia smiled, but that small triumph was short lived, as Nightmare's hoof wrenched her student's head back, giving her a clear avenue to shove her rod down her throat.

The purple blob gagged, her entire body wobbling as Nightmare climbed atop her belly for a better vantage point. Over and over again, the demon-mare's cock slid down her throat, emerging from her mouth with a coating of saliva and occasional streaks of blood. It wasn't long before, with a final grunt, the demon-mare came, pumping what was doubtless gallons of rancid princess spunk down the blob's gullet.

Twilight moaned as her belly filled, but after a few moments, those moans turned to groans of panic. The rings of flab surrounding her hooves wobbled, her eyes shooting open wide to stare Nightmare's undercarriage, almost imploring her to get off, but there was no such relief to be had. Celestia stared for a good few minutes, watching the two flail together, before she understood what was going on.

Ever so slowly, Twilight's belly rounded out, folds of flab disappearing as her skin grew taut. Her belly was massive, the stomach within distended beyond all reasonable measure, but even so, it was nothing against the onslaught of Nightmare Moon's hellish sperm. Tears began to form, little spurts of yellow lard spewing forth to spread across the floor, and then, with a final squeal, Twilight's belly burst like an overfilled balloon.

Chunks of meat and fat flew across the room, spunk and liquid lard, puffs of backed-up wind and globs of other, less identifiable substances splattered across Celestia's front. A hunk of lard hit her in the eye, and she squeezed her eyes shut, waiting for the horror to end. It never did, but when she finally opened her eyes, all that was left of Twilight were a few shattered bones... And her head, still impaled through the mouth on Nightmare's rod. The demon-mare took a step towards her, and the head slipped down with a sickening sound and bounced across the floor.

Even more sickening was the sound that came after, a wet slurping noise that sent a shiver of discomfort down Celestia's spine. Nightmare's cock drooped down, prodding against a hunk of what was once Twilight's flank; The tip opened up, wider than Celestia would've thought possible, and... Consumed the meat, sucking it down the hole like a vacuum cleaner. She could see the chunk sliding down her urethra, bulging out... Oh, Faust, she was going to be sick...

It took a good while for Nightmare Moon to finish her meal, and when she was finished, her nutsack bulged with chunks of meat suspended in fat and blood siphoned from the pool on the floor. Though her sack was as big as a pair of medicine balls, there was still an ocean of gore across the room, enough to feed the city for a week. Celestia's stomach churned at the charnal sight, and even more as Nightmare turned to her, a glob of old lard almost slipping from the tip of her cock, only to be sucked back in with a wet squelch.

“Now, sister, are you ready for your meal?”

Celestia's jaw was wide with shock as she watched the horrible fate of one of her once-brilliant pupil. Nightmare Moon's cruelty never ceased to shock her, no matter how many atrocities unfolded before her very eyes. When Nightmare's words hit her ears, a bolt of panic shot through the princess's mountainous body, but there was no way to resist as Nightmare's magic gripped her jaw, holding it open as she shoved her massive stallionhood in. Unlike Shining's jaw, Celestia's really did crack, a bolt of pain shooting through her body as it snapped out of the socket to accommodate the barrel-like girth.

Celestia's gag reflex was long gone, yet she still felt the urge to vomit as her sister's cock slid down her throat. The pain and humiliation were just as strong now as they were years ago, when her sister first showed off her new stallionhood. If it were just a little bit smaller in girth, she could've summoned up the energy to snap her jaws shut and decapitate the demon's royal scepter, but Shining's former body was just too big, despite the damage malnutrition and the inevitable consumption of dark magic had done to his formerly imposing body.

“Can you taste them, sister? Your niece and your captain? I think their souls are still there, trapped within my glorious girth. Can you hear their screams?”

As it happened, she couldn't, but with a cock longer her entire torso slamming down her throat, she could barely hear her sister's voice, or even her own thoughts. At times like this, the greatest mercy of all – Forgetfulness – Washed over the former princess's mind, making her less of a pony and more of an oversized fucktoy, grunting and farting as her sister made use of her abused orifices. Her stomach was an ocean of acid, and as the tip of her sister's cock forced it's way through the upper gateway, it was inevitable that it'd get a little splash.

The power of her acid was enough to fully dissolve a lesser mortal, as more than a few of her once-equine pounds could attest, but Nightmare's cock was made of sterner stuff. Instead of melting or even burning, a few boils formed around the tip of her flare – Painful, but for the demon formerly known as Luna, pain and pleasure were interchangeable. She was a true demon, an icon of sin, and through her, the pleasures of the pit found a medium in the waking world.

A cackle rose in the demon-mare's throat, a full octave deeper than usual, with a strangely warped effect tinging the edges of her speech. As she did so, a faint black miasma rose from her open mouth, swirling through the air like a glob of oil in water. When she looked down at Celestia, her eyes seemed sharper than before, glowing like a pair of magelights in the dark chamber.

Pure evil coursed through her veins, a form of black smog replacing her blood, blowing from her nostrils with each heavy breath. Celestia had seen it many times in mortal sorcerers who went off the deep end, but for an alicorn, with their near-infinite wells of magical energy, it was nearly impossible. Centuries ago, a minor princess suffered from it after some intense studies in love magic – Celestia always wondered what happened to poor Princess Chrysalis – But watching it affect her own sister, evil though she was, was a painful experience, and not just because of the cock stretching her throat beyond all natural limits.

Nightmare's horn cracked, snapping sharply back as if struck by a harsh blow. Shards of broken keratin and alicornia rained across the floor, but Nightmare only grunted, not in pain, but discomfort. It bent forward again, a little higher up, and at the top, fragments broke away from the tip, turning the sleek point into a brutal, jagged blade.

Her entire body seemed to shudder and shake as it began to expand, daemoniac corruption flooding her system at an unrelenting pace. She did nothing to fight it, simply laughing as her musculature shuddered and expanded, her biceps rising like dough, her withers cracking and spreading outward. Pure strength, tempered only by ambition and cruelty – That was the mark of a true tyrant. Sombra never understood that, which was why his only recourse was the complete temporal displacement of his empire. Nightmare understood, and because of that, hellbound spirits of tyrants flooded into her body, rapists and slavemasters merging with her very soul in a manner similar to the fate of her former slaves.

Pinpricks of pain spread throughout Celestia's throat, growing more intense every passing second, but it was only when Nightmare withdrew her cock, then thrust it forward, that she realized a row of spines was growing across her sister's cock, each one curved backwards to catch flesh in a jagged hook. Another thrust left jagged scars in Celestia's throat, and when she screamed, all that came out was a burble of blood which oozed down her many chin flaps.

Lava-hot precum oozed into her stomach, burning like chunks of hot coal. In a way, she was lucky that she wasn't swallowing the stuff, or that'd be the end of her throat, not that Nightmare's cock wasn't doing the same job with it's new blades. A new wave of sweat broke out across her body, rivers of grease pouring from every crack in her flab, every oversized pore, and pretty soon, a pool of sweaty sludge was spreading across the floor, dissolving what little remained of the golden marble inlay.

Her stomach acid began to boil, producing gas which battered against the blockage in her throat; A few puffs blew up the former stallion's cumpipe, adding to the girth of Nightmare's balls, but most of the wind blasted from the other end, sending a wave of toxic gas into the room's already-poisonous atmosphere.

If Nightmare Moon noticed her sister's distress, she didn't show it, simply planting her hooves upon the tire of lard around her head and ramming her cock down her throat again and again, her hips slapping against Celestia's lard-laden neck. Her mutations were speeding up; Her body went beyond that of any reasonable weightlifter and into the realms of freakish fantasy, with biceps as big as her head, legs as thick as tree trunks; Her midsection bulged out as another layer of muscle formed atop her already-chiseled abs, looking almost like a potbelly made of pure muscle.

The -thing- opened it's jaws, revealing more teeth than any creature had a right to have, and let out a roar that echoed through the palace and across the ruined city beyond, nearly ripping Celestia's eardrums apart with it's sheer volume. Pain coursed through the alicorn's body, from her ruined throat to the pit of fire in her stomach. She wished – Oh, by Faust, she wished she could die, but that release was eternally forbidden to her, the guardian of Equestria, whose failure to help her sister was now leading to the destruction of the world.

Nightmare's jagged horn illuminated, not with magic, but something else, an energy so alien that even Celestia's extensive occult knowledge couldn't touch it. Her body – The horrific, twisted parody of equine beauty that it was – Began to shudder, and with a final roar, Nightmare's cock erupted, sending a flood of liquefied alicorn down Celestia's throat.

The massive mare screamed in agony as rancid, burning-hot semen poured into her stomach, turning it from a mere furnace into the heart of a volcano. The gas spewing from her backside cranked up a notch, blowing from her nostrils, her tear ducts; Her belly creaked and groaned as it expanded to accommodate the growing sea of sperm, a hundred million potential foals... Or, more likely, pit-spawned demons.

At long last, the flow subsided, and the thing that was once Nightmare Moon snorted, withdrawing it's weapon from Celestia's mouth. The ruined mare groaned, a soupy mix of sperm, blood, and gore pouring from her mouth in it's wake. She was so full – So close to death, but it would never come. Already, she could feel her body's natural healing process beginning, torn cells knitting themselves together within her ruined throat. The fire in her midsection began to die down, turning from the heart of a volcano to simply an industrial incinerator; Agonizing, but almost tolerable. The pain began to fade, and with it, her consciousness; Her eyelids drooped, a ragged yawn escaping from her mouth before morphing into a fit of bloody coughing.

The last thing she saw before she drifted out of consciousness was the demon-mare's backside, silhouetted against the ruined spires of Canterlot.
