The Night To Last Forever

III: The Sun, Eclipsed

The library was buzzing with activity. Flustered ponies ran from aisle to aisle, many carrying a multitude of books in their magic grasp. They’d scan the shelves, find the books they needed, before dashing to the next. They searched until they could carry no more, at which point they'd dash through the library to a set of hastily arranged tables. There sat yet more ponies, who desperately toiled through the books they were being handed by the runners. Sweat poured down their faces as they skimmed the pages, searching for advice that may well not have existed. Once a book was done with it was tossed aside onto a pile – a pile that quickly swallowed much of the room.

Many floors above, Princess Celestia paced back and forth, her throne room thick with guards and assistants. She could barely move for the throngs of ponies, and the constant hubbub of clanking armor and clamoring voices was driving her insane. But as annoying as this all was, she knew why the ponies had flocked to protect her. The threat of the nightmare was so very real now. It had been hours since her student and her friends had gone out to vanquish her sister, yet the moon still hung solemnly in the sky.

Celestia knew what this meant. Everypony did.

It had only been when a panicked mail-mare arrived from Ponyville with news that the residents of Canterlot realized the gravitas of the situation. Shining Armor had taken it upon himself to mobilize his guards when word came through of the Nightmare threat. They'd marched out onto the streets, ushering everypony into their homes. Only the strongest and the smartest remained, and they were herded into the castle to assist.

One of those ponies was Moondancer. She bolted down the castle hallways, her legs a blur as she shoulder-barged guards out of the way. Floating above her head was an aged tome. After an especially long run she arrived at Celestia's throne room, throwing open the doors. Only to be greeted by at least thirty armed guards. They returned to ease when they saw who it was. Celestia slouched back in her throne, ushering the mare over. Hopefully she had some half useful advice.

“P-Princess,” the mare gasped, struggling between breaths, “we think we've found what we need... It's not good though.”

She thrust the book forward, slamming it down against the edge of the throne. Once the dust had settled, Moondancer flicked the book open to the page she'd marked earlier. It listed a host of details regarding corruption. More specifically, the cures.

“Now then, if the mail-mare's babbling were really anything to go by, Nightmare Moon corrupts, primarily, through sexual activities. She will – *ahem* – have her way with her victims, before flooding their bodies and minds with her dark influence. Once those corruptive substances are inside the body, there is no way to stop their effect. No spells, no potions, nothing. Except for one thing...”

The Princess raised her eyebrow quizzically. Several guards shouted outside, but their voices were too muffled to make out. She motioned her hoof for the mare to continue.

“You see, there's only one thing that can completely stop a source of influence, and that's destroying the source of influence. We've concluded that if you can revert Luna back to her original form and destroy the Nightmare, then all the other ponies will revert too. If we can do- ”

A bone-crunching thud shut everypony up. The chattering of guards, the fluttering of pages, all stopped. Sprawled out across the balcony, Celestia could make out one of her own soldiers. A Pegasus, he appeared to be gravely wounded. As Celestia rose from her throne and approached, she could easily make out the cause. A smouldering wound, stretching from his flank to his shoulder. Clearly the result of a powerful spell. The energy had pierced his armor, severely burning his fur and skin. Celestia grimaced as the guard removed his helmet, exposing the full extent of the damage. Celestia span round to face her staff.

“Can somepony please get this stallion to a medic? NOW!”

Several shaken ponies dashed forwards, trying their best to carry the soldier without coming into contact with the wounds. From his cries of anguish, they weren't doing a good job.

With the wounded stallion out of the way, Celestia strode out to her balcony. She surveyed her kingdom.

The streets were crowded with soldiers. Hundreds upon hundreds lining the roads alone. They all carried various offensive weapons, though they were crude in comparison to the magic Nightmare Moon could wield. Several medical tents had been hastily constructed, most of which were already filled with pegasus, all sporting similar wounds to the stallion before. The remaining pegasus and the unicorn guards had surrounded the castle gate. Clearly Nightmare Moon and her allies were on the other side, and from the look of the burnt pegasus soldiers, they'd been taking pot-shots at anypony who flew overhead.

The massive, fortified gate shook violently. The reinforced wood rippled and splintered as it was continuously blasted by an onslaught of Nightmare Moon's strongest magic. It was truly tragic they'd had so little time to prepare defenses, or else Celestia and Shining Armor could have developed some sort of protective spell to better defend the city. Alas, time had been too short, and now only the crumbling wall stood between Celestia's citadel and her greatest enemy.

A final, almighty spell tore those defences down. The air was filled with dust and noise as the ancient brickwork disintegrated, and Nightmare Moon and her followers stepped through into the city. Refusing to show any sign of weakness, Celestia leaned forwards over the balcony. The huge array of guards in her throne room cried out as she dropped out of sight. They'd been posted here by Shining Armor to protect the Princess, yet there she went to fight her all-powerful nemesis herself.

She plummeted downwards, before spreading her wings and landing graciously beside her guards. Her voice was cold, calculating, threatening.

“Nightmare Moon, hear my warning! You cannot and will not win! You may think you have the upper hoof, but you number seven, and we number hundreds! You may have corrupted my student and her friends, but the power of friendship will be your undoing! Step down now, and we can all walk away. Please, sister...”

Nightmare Moon brushed some of the settling dust from her flank with one of her wings. She took great joy in ignoring her sister's demands, watching how it got under her skin. She waited for the Princess to finish, before nonchalantly tilting her head to the sky. Celestia's eyes followed.

At first, nopony could quite understand what she was looking at. The sky hadn't changed since the beginning of the night. Still a dim shade of purple. Still well illuminated by the moon, which hung far closer to Equestria than it naturally should. But there, faint at first, Celestia spotted a change. A patch of sky, perhaps a few hundred feet up, had started to grow black. But this was like no darkness Celestia had seen before. It was a solid wall of black, slowly beginning to expand. Before long it had become a gaping maw from which no light appeared or escaped. Celestia could hear scuffling footsteps as several of her guards broke rank in fear. But she and her good stallions would not break, for anything.

A cloud of purple energy seeped from the void, before a swarm burst free. A swarm of bat-ponies. They blotted out the moonlight as they cascaded forth like a wave, some tumbling gracelessly to the streets, others swooping out majestically over the city. The time for action was now.

The Royal Guards charged forwards, clashing with the bat-ponies. As their weapons met, ponies began to scream, and Nightmare Moon couldn’t help but laugh. She and her loyal brood remained still, staring down the Princess. Celestia gritted her teeth before spreading her wings and fleeing. She had to draw Nightmare Moon away before she could hurt anypony else.

Nightmare Moon scoffed at the pitiful spectacle of Celestia trying to run. She turned to her brood.

“Ladies, I have a hunt to attend to. Please, help yourself to breaking in the townsfolk. Remember, a little bit of me is inside of you all now, so you know what must be done.”

Twilight watched her master as she spread her wings and gave chase to the coward. She could feel her cock beginning to twitch in anticipation. This was going to be beautiful.

Flying as fast as she could, Celestia scoured her kingdom. The void remained open, but no more bat-ponies flew free. Her guards were holding the enemies’ attention, meaning they couldn’t attack any of her citizens. It was then Celestia spotted figures emerging through the dust of the old wall. In through the gaping, smoldering ruin clambered a gaggle of ponies. It took Celestia a while to recognize them, but soon she realized who they were. Corrupted citizens of Ponyville - easily numbering at least fifty – had begun to pour in. Clearly they were here to help spread Nightmare Moon's corruption.

A bolt of purple energy whizzed past Celestia's ear. It missed her by a fraction, and thankfully so. No one could comprehend just how powerful that alicorn was. She arced her head back, craning her neck to spot Nightmare Moon in the darkness. She laid eyes upon her, flying just a short distance behind her. While Celestia flew with ease, it was taking Nightmare Moon all of her concentration, as the hideous mess of male genitalia she'd been forcibly bestowed was weighing her down.

“Your shameful lust slowing you down, dear?” Celestia couldn't help but taunt the mare as she struggled to keep up. The decision to give her sister those freakish genitals with no source of release had always plagued her mind. In those thousand years away she'd wondered if it had been a punishment too far. But in the adrenaline-fueled heat of the moment, it was the best choice she'd ever made. She shook her rump jeeringly, tittering to herself as Nightmare Moon fired another bolt which missed the target entirely. Why not make a game of this? Celestia closed her wings, plummeting down towards the city. “Let’s see how well you chase me among the buildings,” she thought to herself.

Down on the streets, she could see things weren't such plain sailing. Her guards were occupied, and so no one had been able to stop the Ponyville residents. She saw a couple trying to tear down some pony’s front door, using brute force to batter their way inside. Whatever they were going to do wouldn't be pretty, but she had no time to stop. The sound of whistling wind behind her reminded her of the demon on her tail. She pulled upwards again.

As the door turned to splinters before them, Big Macintosh and Doctor Hooves stepped into the house. Floorboards creaked as they moved inside, beginning to search each room meticulously. Turning over beds, wrenching open cupboards, all to no avail. Big Mac shuffled awkwardly from hoof to hoof. His member was as stiff as a board, twitching eagerly with the excitement of the prize he'd been offered. Before his master had left for Canterlot, she'd called all of the Ponyville residents to her side.

“My loyal subjects! Tonight is a new night. One in which we tear down what stands, and rebuild in my image. We shall march on Canterlot, and you all have one simple goal. Find the ponies, wherever they are hiding, and break them. Spill your majestic seed into their worthless bodies, and break them. Whoever breaks in the most stallions and mares will win a most honorable place by my side. The rest of you will become my breeders. I pray you all understand the stakes...”

And Big Mac surely did understand the stakes. He wanted that place by his master's side, he needed it. Every thought that went through his head was of her, of pleasing her. He couldn't allow himself to become a lowly breeder, when the promise of a place by her side was so tangible. He wouldn't allow it, he was going to get what he wanted. By any means necessary.

His ears pricked and his nostrils flared when he heard screams from the adjacent room. Dashing round the corner, there was Doctor Hooves. He'd found a mare cowering under a bed, and was trying his best to drag her out from under it. His teeth locked around her tail, he tried and tried, but he couldn't get a grip on the wooden floorboards. He turned as Big Mac entered the room.

“We've got a live one here! Help me pull her out and we can work together to snap her mind like a twig!” He giggled inanely as Big Mac strode forwards, before yelping as he slammed him across the room. Doctor Hooves landed, a crumpled mess on the floor, and by the time he had righted himself Big Mac was dragging the mare out of the room by her mane.

Colgate groaned and cried to herself as she bounced down each step to the ground floor, before being pulled out onto the cobbled streets. She had buried herself under her bed the moment the wall shattered, so now she could see the full extent of the chaos.

Princess Celestia darting around the sky as Nightmare Moon launched a barrage of purple beams at her. Royal Guards being dragged to the ground by bat-ponies, before being jumped on by the horny crowd. Mares and stallions alike being torn from their houses, only to be used and abused right there in the streets. She gulped back yet more tears. That was what was going to happen to her. Looking up, there stood Canterlot Castle. In the madness of the streets, that place seemed calm, tranquil. The warm orange lights still shone out, and one could occasionally make out ponies going about their business inside. Meanwhile here she was, with a stocky red earth pony stood on her mane.

In the cool glow of the moonlight, she got a proper look at her captor. He didn't look very different from any normal pony, excluding the unnaturally vast set of genitals that hung below his body. Colgate peered her eyes up at the stallion as he shuffled around her, keeping a muscular hoof on her mane. This was it.

Big Mac didn't have time to worry about those niggling little details, like whether or not this mare would be able to handle the full extent of his member. He needed to break her and move on. He ignored the mares squirming as he pressed the head of his cock against her labia. He ignored her violent shaking as the rest of his shaft followed it inside. And he ignored her screams of discomfort as he began. He worked quickly, pumping his hips back and forth with selfish speed. The sounds of muffled sobs simply floated past him as he used the hole he had graciously earned. The cries would stop eventually when this mare saw sense.

And sure enough they slowly did, as with each powerful thrust more and more globs of pre-cum flicked from Big Mac's cock into the mare's pussy, seeping down into her uterus. That strange, corruptive influence took effect almost immediately, quickly locking Colgate in a stranglehold of desire. Within moments the tears had stopped and she had begun to buck her hips in time with his, moaning perversely with each slap of his balls against her underbelly. No sooner than Big Mac felt the churning of his balls, he embraced the call. He took no effort to slow his orgasm, he needed to move on. He let out a deep, primal growl as his warm load shot free, coating the mare's innards a delicious white. The moment he felt his orgasm ending, he wrenched his cock free, leaving Colgate to stumble to the cobbles below. The stallion bolted, looking for the next mare to claim, as Colgate laid in the seed that dripped free of her stretched lips. She had lost all the energy to fight, all she could sense now was an odd, warm feeling taking hold of every inch of her body. Embrace it.

Celestia was starting to panic. Her guards were being overrun, and soon there would be no one left to defend her citizens. She had to trying to bait Nightmare Moon away, and instead turn and fight. She'd wanted to do this without violence, but clearly it was the only option. She banked sharply, turning to face her sister. As she turned she glanced down at the city below, only to find her eyes drawn towards a particular sight.

Small and blurred from this height, the scene was difficult to read. But she quickly realized just what was happening. It was Twilight Sparkle. That incredible unicorn, whom had shown so much promise, had truly fallen.

She had cornered her brother in a darkened alleyway, effortlessly deflecting the spells he fired her way. Batting them aside like flies, she'd easily been able to pounce on the confused stallion. Before Shining even knew what was happening his sister had buried her demonic futanari cock deep inside his rear, pinning his head to the floor with a powerful spell. She watched as his cock – puny in comparison to Twilight's mighty appendage - bounced uselessly between his legs with each of her thrusts. Twilight couldn't help but smirk at the sight of it, before being snapped back by his sniveling voice.

“T-Twily, why... please stop this...!” the unicorn groaned, his body in agony as that unholy cock punched past his colon. Every inch of his skin crawled as Twilight abused his rear, the discomfort too intense to comprehend.

“Shut up, Whore. You belong to our savior now. Embrace it or don't. Either way your ass is going to get raped by every horny stallion in town.”

As she rhythmically thrusted against her brother's raw behind, Twilight leaned down to whisper into his ear.

“But don't worry, even after you get humiliated by every stallion, mare and foal in Equestria, I know I'll be your favorite. Well, after the Master, of course.”

Tears were beginning to well up in the corners of Shining Armor's eyes. Vivid images flashed through his mind of the good old days. The days when he and Twilight were younger, playing games and reading stories together. But now here they were, at the end of the world.

Going out not in style, but in shame.

Shining Armor screwed his eyes shut as his sister's pounding became stiffer and faster. Her breaths had started to grow short, and a dull – yet building – moan had started to escape her lips. With a sudden yell Twilight buried the entirety of her shaft in Shining's anus, thick ropes of cum shooting free of her cock. The sensation of this incredible liquid flowing into Shining all became too much for him, as he felt his own orgasm peaking. With a soft, feminine gasp he basked in the feeling of semen dribbling free of his own cock, while a never-ending wave was pumped into him. When it finally did come to an end he could feel his legs going weak and his mind starting to cloud.

Every facet of his mind was screaming that he needed to fight, but he couldn't for the life of him think what he had to fight, or why. The voices of rebellion grew quieter and quieter, until only one thought occupied his mind. Find Nightmare Moon, and bow to her demands. He glanced up, dazed, as Twilight began to trot away, semen still drooling from her shaft.

“...Twily, are you going to see Nightmare Moon? Can I come?”

“Soon, Whore, I shall be. But for now you need to rest. You look brain-dead, and that was after one short breeding by me. If you go near Master anytime soon, she'll probably break you in half.”

And with that she continued on her way, leaving her burbling brother to lay in the alley.

Celestia didn't know what to do. If that was the sort of influence Nightmare Moon was capable of wielding, what chance did any pony have? Thoughts were flying around her head, but everything drew a blank. She slowed her flight, unable to concentrate on anything anymore.

Searing pain tore through her wing as one of Nightmare Moon's shots connected. Celestia had slowed to a crawl; she'd been an easy target. Screaming unintelligibly, the Princess plummeted downwards. With an astounding thud she crash-landed into one of the city’s many back alleys. A pile of trash broke her fall, but the pain was still agonizing. Taking a brief moment to study her wing, Celestia saw many of the same wounds that Pegasus guard beforehand had sported. She knew a variety of spells that could heal her wound, but they would take time. Time that she, categorically, did not have. Glancing up Celestia had spotted Nightmare Moon circling overhead, a couple of well-endowed bat-ponies having joined her in the hunt.

“Psst!”

Celestia snapped to attention. Was that the wind? Wherever she looked she couldn't spot another pony, other than those above her, and they were too far away to be able to hear. There it was again, this time accompanied by the creaking of metal. Celestia whipped round.

The whispers had been coming from a large dumpster a short distance from where she'd crashed down. Somepony crouched inside began to open the lid. Celestia recognized the face of Blueblood as he emerged.

“Hello Princess! I was watching your tussle and decided to wait for you in case of emergency! I-In the trash can. Hiding in there? Don't be daft! I'm here to help! Y-Yeah...”

His voice was wobbly and raw, as if he'd been crying. Celestia didn't have time to dote for this coward, though. Nightmare Moon would be upon them any moment.

“Come on, Blueblood. The Castle will still be safe. We need to move, now!”

As surreptitiously as possible, the two darted from alley to alley, cloaked in darkness. The streets were rapidly filling with ponies in the most humiliating of activities. Bat-ponies had descended on her innocent citizens in gangs, using them as they saw fit. No sooner had they finished their beastly business they were off again, searching for some new prey to break. Celestia watched a gang of four bat-ponies fly away from an unfortunate mare, her belly so swollen she could barely stand. The mare wobbled to her feet, took a step, before stumbling to the floor again. Corrupt semen dripped from her every orifice, and it was clearly having the desired effect. It was only a few seconds later she'd begun to masturbate. Celestia sighed. She wanted to help the poor mare, but nothing could be done. They had to press on. Canterlot Castle had just honed into view.

The place seemed to be abandoned. The guards on the approach had left their posts, either fleeing or being picked off by the others. The warm glow of the lights inside had been snuffed out, save for a few windows on the higher floors. The doors hung open invitingly.

“P-Princess, are you sure this is wise? The place has been ransacked! They'll be waiting for me! US! They'll be waiting for us...”

Silent, Celestia crept forwards, sliding through the gap in the open doors. The interior was a mess, but there was no sign of life. Friend or foe. She began to move at lightning speed, leaving Blueblood to frantically run after her. He found her staring at a small section of wall in an adjacent corridor. As her horn began to slowly light the hallway, bellowing voices erupted outside. They'd been spotted. Blueblood hopped from hoof to hoof in worry as the Princess focused her horn on the wall.

The grand doors flew open as a horde of ponies – some bats, some lust fueled stallions – burst into the hall.

Grunting with the effort, Celestia's spell was finally completed. The small section of wall faded away, revealing a hidden passage. Blueblood bolted inside before Celestia could so much as take a step. She quickly followed him inside, before training her horn on the faded brickwork again.

The sound of hooves were getting louder.

She needed to complete the spell, quickly.

Closer still.

Almost there.

Celestia suddenly found herself staring at one of her own citizens, his face full of blood-lust.

He lunged forwards, before Celestia finally managed to complete her spell. The faded bricks grew solid again, beginning to glow a light yellow as her magic coursed through it. Breathing a sigh of relief, she headed down the passageway.

Fancy Pants battered his hooves madly against the wall. Other ponies had crowded round him, watching his efforts. They spoke angrily, accusing one another of failing to catch the prize in time. But that all stopped as Nightmare Moon appeared behind them. She sauntered down the hallway as ponies stood aside for her.

“So, my subjects, would one of you care to tell me why we are all so fascinated by a wall?”

Fancy Pants spoke up, nervous.

“W-Well, your Majesty, we had nearly captured the false Princess. We were right on top of her, but she vanished into some hidden passageway...”

He tapped his hoof on the wall, causing small sparks of yellow magic to flicker around it.

“...But she's used some kind of incantation, we don't know what to do.”

Nightmare Moon stepped closer as Fancy Pants shrunk away. He watched fearfully as she studied the wall. Quizzically she pressed a hoof against it, before beginning to conjure some kind of spell.

“Master, I'm afraid that won't work.”

Gasps and cries emerged from the crowd. Who had dared to speak against their savior? Their punishment would surely be swift, and incredibly painful...

Twilight Sparkle approached. She walked slowly, as her brother followed closely behind. He had his muzzle buried deep inside his sister's asshole, feverishly running his tongue around the warm walls of her body. Pre-cum dripped from his stiff cock, and his belly still audibly sloshed with each step, his sister's sperm warming him nicely. Nightmare Moon couldn't help but feel proud at the sight. Twilight Sparkle was her student now, and from the looks of the stranglehold she held over her brother, she was learning quickly.

“You see, Master, that passageway leads to the Royal Dungeon. The false Princess uses powerful incantations to keep it hidden, and even more powerful ones to keep it locked. She built it as a place to experiment with more powerful magic, and discipline those students of hers that had been bad. Magic will not be able to break that wall down, the incantations are too powerful. The only thing that can break it open, is force. Force that no pony can exert.”

Nightmare Moon mulled over this new information. She didn't need to ask how her student knew this, all that mattered was that she did. And besides, she wasn't going to lie to her. Nopony was. They all loved her too much.

The small crowd around her shuffled awkwardly, trying to think of what to say. Nopony dared suggest anything, in case they were punished for their hubris. Suddenly they all felt calmer as she began to smile knowingly. She strode out of the castle into the courtyard, causing everypony to dash out after her. A massive crowd had formed outside, made up of almost every pony in Canterlot, and many from Ponyville too. They all wanted the False Princess' head, and she had a plan that would get it for them. Nightmare Moon called Twilight forwards. She stepped out in front of her master, her brother still in tow.

“Get rid of the colt.”

Twilight hissed at her brother, watching as he squirreled away into the crowd. Settling besides the other lowly slut-ponies, some began to reach forwards, petting and groping him. They couldn't believe he'd been so intimate with a pony so close to the Master.

“GET AWAY FROM THAT! IT'S FOR MYSELF AND THE MASTER ONLY!”

They yelped in shock as Twilight bellowed at them. They shrank back.

“Now, Master, you needed me?”

Nightmare Moon grinned down at her.

“Yes, my child, I did. As you said, brute force is needed to break that wall down, correct? Brute force no pony could put out. Well then, I can only think of one thing that will work in this situation. Be ready.”

Sparks of dark purple energy flung themselves from her horn, fizzling out on the ground around her hooves. Twilight closed her eyes, excited for the almighty ability she was about to be granted. The sound of the spell grew louder, and louder. The crowd was silent, watching with intrigue.

A crash. The sound of splintering wood. Twilight peeled her eyes open.

Between her and the Master was a large wooden wardrobe, mostly in pieces now. Using her telekinesis, Nightmare Moon casually wrenched the doors clean off, throwing them away. And out from the wardrobe, dazed and confused, emerged Spike.

He screamed when he realized where he was, and who was staring down at him. But before he could speak Nightmare Moon had lifted him into the air using her magic. With little effort she had summoned some kind of gag, which she carelessly shoved into his mouth before fastening it behind his head. She laid him down on the floor in front of Twilight, holding his rear up invitingly.

“Do it for me.”

Only too eager to oblige her Master, Twilight stepped forwards. The dragon squeaked and groaned as his friend from birth clambered over his prone form. She was infinitely more powerful than him now, there wasn't any way he could stop her. Tears began to flow down his face as he felt his asshole being slowly pushed open. He was sick with fear, the baying crowd cheering and whooping. They grew even louder as Twilight began pushing her pulsating cock deeper into his rectum. They could see every inch of her girth through the dragon's body, so small and petite that he was brutally stretched immediately. Some of the worst discomfort he'd ever felt, he tried desperately to wriggle free. But with every try, Twilight just pushed deeper and harder. Listening to the bated breaths of the crowd, she withdrew, every inch slow and deliberate. She didn't dislodge her cock from her friend's rear entirely, instead leaving the swollen head buried inside.

Pausing for a moment, she took a breath.

Then she slammed her entire penis into his rectum. Cheers erupted from the crowd as his abdomen bulged around the foreign body inside of him. Her hefty, bloated balls smacked against him, making a beautifully satisfying sound and feeling. Shining Armor could feel himself getting hot and bothered, this sight and smells turning him on no end. He dropped onto his haunches and began to play with himself, just as many of the other ponies had started to.

As Twilight's onslaught continued, she could feel Spike's body loosening around her. Being so small his body just couldn't handle the abuse that a normal pony could handle. A shame really, because Twilight wished the incredible feeling of his anus would last forever. But her own feelings were not important right now, and she was foolish for letting them cloud her Master's wish. She needed to mate him, break him in. Twilight glanced up at Nightmare Moon.

“Am I doing well, Master? Do my efforts please you?”

Nightmare Moon paused before speaking, listening to the sounds of Spike's tearful moans.

“Of course, my most loyal of followers. The first part of your task is nearing completion. Please, fill him with your seed. Drown his spirit in our corruption.”

With this instruction, Twilight quickly sped up her motions. She'd been taking it slow, not wanting to rush the moment. But if the Master wanted closure, that was what she'd get. Twilight lurched forwards violently as her orgasm pushed her over the edge. Considering that she'd bred her brother mere minutes earlier, she'd expected this orgasm to be rather more feeble.

But far from it. Her body involuntarily spasmed as the effort took hold. Her loins felt like they were on fire as thick string after thick string of cum launched into Spike's body. His incessant whining had finally stopped, leaving him lying in silence as the corruption took hold. When Twilight had finally run dry, she slowly withdrew, careful not to spill any of her seed to the floor. Again, she glanced up at her Master for praise.

“A most impressive copulation. You'll be a fine breeder. But that is a machination for the future. For now, we have a wall to destroy. And the creature before you – his veins now seething with our corruption – will be the beast to tear it down. But first, we need him to want it.”

She leaned down towards the baby dragon, before bellowing in its face.

“Spike! Stand to attention! Your Master demands it.”

The dragon wobbled to his feet; dazed. His new mind was still a little shaky. His body was all in order though. As his eyes came to rest on his Master's genitalia, he couldn't stop himself from becoming hard. The lock of the gag clicked behind him, before falling to the floor.

“Good. Now, Spike, it is time for you to take what you want. Look around you, at the crowd. All those mares, mindless cock-slaves, eager for nothing more than to birth young. Smell the air, that scent, it's indescribable, no? The smell of horny mares. You could just drink it. All horny for you. Pick one.”

Nightmare Moon waited quietly as Spike's eyes scanned the crowd, licking his lips in anticipation. The corrupt alicorn couldn't help but smile, watching as Spike began to slowly grow taller. Her plan was going to work perfectly.

His eyes continued to scan the crowd, but he couldn't spot the particular mare he was looking for. Exasperated, he stamped his foot on the floor.

“Where is Rarity? Spike wants Rarity!”

Twilight snickered as Nightmare Moon closed her eyes. With infinite magic, she would easily be able to summon Rarity to the front of the crowd. And moments later, there she was. The ordeal she'd gone through at the Castle of the Two Sisters was still very much apparent.

Vast quantities of Twilight and Fluttershy's spunk still resided around her mouth and pussy, the cool wind causing it to dry in place rather rapidly. Her facial expression was rather ditzy, flushed red at the sight of a horny male. Her belly and womb was still incredibly bloated, having not had the chance to fully digest the vast quantities of spunk yet. But Spike barely noticed any of this as he shoved her to the floor.

Rarity yelped. She'd expected this little dragon to be respectful, perhaps even honorable around her. She, one of Master's original broodmares. What she hadn't expected was to be manhandled to such an extent.

For a little dragon, he had an impressive strength. Rarity tried to remember if the dragon had always been that strong, but it was useless. Her mind was all but vapor, her memories of the time before lost forever. But Rarity snapped to reality when she felt cold claws dragging against her flesh. Spike had pushed her onto her back, so now she stared down at him as he began to fondle her abused holes. Having already been plugged by her two futanari friends so thoroughly, she could feel herself still gaping slightly. As such, Spike had no difficulty guiding his cock into her anus.

She’d never felt dragon cock before, but perhaps Spike hadn’t been the best place to start. Only being a baby, his girth and length were really rather pitiful. No sooner had he started to push against her he seemed to be done, withdrawing for another thrust. Sweat had begun to build on his brow already, and yet Rarity could barely feel a thing. Stifled giggles began to rise from the ponies, and Rarity couldn’t help but coo as Spike’s face started to turn red.

Twilight glanced up at her Master. She dare not speak her mind, but she was worried. Whatever the righteous alicorn had planned to do with Spike, it didn’t seem to be working. She gathered the confidence to speak.

“M-Master, may I ask what you’re intending to achieve? Spike is a puny, useless creature. We ponies cannot breed with it, and it is too weak to fight. I thought that was why you wished for me to entrap it back in Ponyville?”

She quickly shut her mouth as Nightmare Moon threw a glance in her direction.

“Oh, don’t worry, young one. Dragons are greedy creatures. But, perhaps you are correct.”

The Master focused on the crowd again, more specifically her breeder and the dragon. She clapped her hooves twice, and the laughter of the crowd immediately ceased.

“Rarity, remove the creature from within you. Get rid of it. He can have you no more.”

Immediately Rarity was on her feet, grabbing hold of Spike with her magic, before casting him aside. He disappeared from view as he slid along the paving, before vanishing into the shadows. Rarity turned and began to meander towards the crowd again. They were clearly disappointed. They’d expected a show. They started shuffling from side to side, waiting for something to happen.

Then, out of nowhere, a roar. It pierced the air, seemingly shaking the very earth. Everypony pricked their ears. Rarity glanced round.

Out from the darkness emerged Spike. He’d changed. No longer an insignificant baby. Running on all fours, he was only a little taller than the average stallion, but he was much, much bigger. Stocky muscles rippled across his arms and legs, and newly formed scales glinted seductively in the moonlight. His eyes shone purple, the Nightmare corruption flowing through him like blood. Thick, heavyset claws dug into the ground, tearing holes in the paving as he galloped forwards. Opening his mouth wide, he let out another primal roar, before leaping through the air.

Rarity screamed as the hostile beast smothered her. Her body churned violently as she felt his weight press down against her belly. The pressure was too much, and she could feel great lakes of semen being squeezed out of her. The sensations only lasted a moment, though, as Spike was quickly stood again. Leering over her, he grabbed hold of the unicorn with ease, managing to wrap one clawed hand around her entire waist.

She stared into its eyes, waiting. She knew exactly what it wanted. Spike’s cock pulsated grotesquely, spilling obscene amounts of pre-cum to the floor. But it wasn’t a laughable size anymore. Anything but. It was now vast, easily the same length as Rarity’s hind-leg twice over. And while the tapered point looked manageable, the base was easily as wide as two ponies stood side by side.

Rarity gulped as the pointed tip probed her anus. She considered begging him to go slowly, but there was no point. She could see it in his eyes, there was no-one inside anymore. Master’s corruption had made his body incredibly powerful, but apparently at the cost of taking his mind. Now he was nothing more than a sex-craving beast, and she was his first conquest.

A guttural moan escaped her lips as she felt her asshole begin to stretch. Inch after inch crept into her body, pushing her apart like nothing ever had done before. The sensations of Twilight and Fluttershy’s members were gone, obliterated from her memory by this gargantuan cock. And glancing down, she could see it was nowhere near completely penetrating her. Her eyes began to water with the titanic effort, her body being permanently reshaped by the member lodged inside her.

Her vision was beginning to fade by the time the dragon finally hilted her. Her body was almost unrecognizable as a living creature, and the crowd was in awe. Rarity could see a huge, pointed lump appearing into her field of view. It was the tip of the creature’s cock, bending her abdomen to allow itself to fit. Her stretching skin rippled as the shaft inside her moved this way and that. The Master’s corruption had allowed her body to stretch far beyond its own limitations, but now it was all too much. Rarity was on the verge of fainting, but she couldn’t try and stop it now. All this build-up, she needed to feel it cum.

The dragon had managed to hilt itself in this mare, before getting several agonizingly slow thrusts in. But even after several thrusts the mare was still too tight for him to manage, despite her gaping anus now being so wide a pony could probably fit their head in it. For the dragon, Rarity’s crushing tightness was too much. It threw its head back and let out a primal screech, before the torrent of seed spilled forth.

Rarity’s cheeks puffed out as the spunk immediately filled her mouth. She hadn’t even been able to prepare. Almost choking, she threw her mouth open, allowing the seed to spill down onto her body. But this was only the beginning of the orgasm. Her stomach ballooned outwards, so much so that the dragon could no longer hold her with one arm. Not wanting to lose the prey, it tightly wrapped its other claw around her in a vice-like grip.

Cum kept volleying into her belly, instantly pushing yet more out of her open mouth. It was a hideous, cyclical process, spilling spunk to the floor as thick as rain.

Nightmare Moon clapped her hooves together again. The dragon immediately let go of Rarity, allowing her to splatter down into the pool of semen below her. Several of the crowd dashed forwards, crowding round Rarity’s anus to lap up the seed that cascaded free. She moaned something inaudible -babbling inanely - before flopping down against the floor unconscious. A pony held her upright, gravity dragging the excess seed from her body. As it rushed free from her holes, several horny mares gathered round to drink the rapidly draining liquid. They’d never tasted dragon spunk before.

The beast trotted over to Nightmare Moon’s side, as faithful as an old working dog. It waited intently for instruction. As the Master began to walk away towards the castle, it followed loyally. The townsfolk followed suit shortly after, shambling after the Master like cattle to slaughter.

By the time Twilight and the others had caught up, Nightmare Moon had already put the dragon to work. Having worked it up into a frenzy, she directed it towards the magic-imbued wall, smiling as it battered its head madly against the bricks.

Suddenly it was all beginning to dawn on her. The defiler she’d once called her sister was so close. All that stood between the two alicorns was Celestia’s shield, bound with enough powerful magic to stop even her. Ironic, really, that it was about to be torn down by the pet of her once-prized student.

Mortar crumbled from between the bricks. The wall was giving way. The moment for action would soon be upon them. Nightmare Moon turned to face her followers.

“Soon, the dragon shall break down the final barrier between us and the false Princess. Once the wall crumbles, all of you will flood in. Destroy any resistance, by ANY means necessary. But bring me her, unharmed. Whoever gets her to me will be keenly rewarded.”

As if to accent her promise, the wall turned to dust behind her. The remaining bricks toppled into a pile, as a horde of ponies and bats surged forwards. Its job done, the dragon slumped away, curling up under one of the trees in the castle’s courtyard. Nightmare Moon closed her eyes, taking a deep breath. It was time.

***

Celestia was anxiously flicking through one of her tomes. She had always known the dungeon was something of a double-edged sword. One way in, no way out. With her, Blueblood and Moondancer - along with a few stony-faced guards and two researchers - all of whom looked resigned to their fate. Dust fell from the ceiling as a clamoring sound grew louder above them. Celestia knew they’d breached the wall, somehow. She slammed the book shut, before yelling at the researchers to give her their books too. They piled them up on the table, numbering around ten. All ancient tomes, adorned with strange, eldritch symbols. Training her horn on the pile, the books were quickly engulfed in flames. The paper blackened and curled as the flames licked around them, destroying thousands of years of the most powerful magic known to Equestria. If Nightmare Moon had gotten hold of those spells, she’d be truly unstoppable.

One of the guards began to splutter as thick black smoke filled the room.

Celestia considered taking a deep breath and letting the smoke take her. She knew she wouldn’t be able to bring herself to do it, though.

The crash of hooves grew louder.

Celestia turned her head to face Moondancer. She’d been sat quietly in the corner, muttering under her breath about something no-one could quite make out. The Princess aimed her horn at the unicorn, before engulfing her in energy. Shocked, Moondancer shot her head up.

“W-What are you doing?” She cried, as startled as she was terrified.

“I’m getting you out of here,” the Princess replied, calm and calculating. “I need somepony capable to get away from all this. You need to warn the other settlements. Go to Manehattan, tell them what’s happened here. Warn them the Princess has fallen, and that it’s up to the others to fight. GO!”

And with that the pony was gone, only glittering yellow energy left in her wake. Blueblood stared over at the Princess, disgusted.

“YOU COULD’VE TELEPORTED US AWAY THIS WHOLE TIME?!”

“No, I couldn’t. The magic barrier encased this whole dungeon, not just the wall. No magic could get in, none could get out. But now the wall is gone, the protective spell is broken. A Princess will never abandon her citizens, but you are free to –“

Ponies poured into the dungeon. Initially confused by the smoke, they spotted the Princess and darted forwards. Yelping, Blueblood encased himself in magical energy, teleporting away to freedom. Celestia could only hope that Moondancer managed to get word to the others. Celestia, the guards and the researchers were all the resistance that remained in Canterlot, and they were quickly drowned under a sea of hooves. The Princess didn’t even put up a fight. She just closed her eyes.

When she reopened them, she found herself strewn out on the steps leading to the castle. She was surrounded by mares and stallions of all sizes and ages, many of whom looked deeply pregnant. Her skin began to crawl as several of the ponies broke down into furious masturbation at the sight of her. Craning her head up, a black silhouette stood over her. Nightmare Moon. Her voice boomed.

“Equestria, you’re Queen is ash at my feet! For a thousand years she tormented me, trapping me on that cold, lifeless rock, with nothing, and nopony! Nothing but the gift she bestowed upon me.” She shook her freakish testicles to the best of her efforts, as a roar of approval rose from the crowd. “I was left to rot in my own thoughts. But now, here I am. The pathetic creature that lies before you has been vanquished, and now the true ruler of this fine nation stands over her. You are all now my subjects, and so you will do as your ruler wishes. To any ponies cowering in their homes who have not yet seen the light, you’d better start running. It would be unfair not to have a head start.”

Nightmare Moon watched as several ponies bolted from their homes, dashing down the streets towards the smoldering ruin of the outer wall. Cresting the last hill, they disappeared from sight. Nightmare Moon looked towards a nearby clock-tower, counting the seconds. With adequate time up, she nodded to a gaggle of bat-ponies, standing by. They took to the sky and gave chase, rapidly gaining on their prey. As they disappeared from sight the air was filled with the sound of screams and moans. They’d caught them.

“Anyway, now that the foolish have been dealt with, we still have the issue of the specimen that lies before us. You all understand that she needs to be shown her place in this new world. And I will show her that.”

She leaned down, whispering quietly into her sister’s ear.

“A world of intense, intense debauchery. Look up at the stars, Celestia. Because that’s the last time you’re get to see the sky a free pony.”

She withdrew to address the crowd again, laughing to herself as the Princess shivered in fear.

“Now, before the ‘Princess’ is forcibly settled into her new role, it would surely only be fair for a ruler to show her subjects a kindness. You have an hour. She’s all yours.”

She tutted as the excited crowd began to lurch forwards.

“Please, first let us address some ground rules. We aren’t savages, after all. First. Any pony that allows her to run is to be shown swift mob justice. Second, if she escapes, you are all to be put to death. And third. Upon my return, I expect her body to be carrying the seed of at least two-hundred of you. I will know if you have failed in this task. If you do, you shall all be severely punished. But I am nothing if not a fair Queen, so allow me to make this task a little easier for you.”

Celestia began to groan something unintelligible, but Nightmare Moon swiftly jabbed her in the side with her hoof. Closing her eyes, she pointed her horn in the direction of the crowd. Celestia - stunned into silence by her sister’s darkness – watched creeping tendrils of purple energy descend upon the horde. They sank down towards the floor, before seeping into the bodies of the excited, clamoring mares. It was not long before the corruption was completed, as impressive, undulating futanari cocks surged free of their loins. The mares looked between one another, giggling excitedly.

“Of course, these effects will only be temporary. You fine young mares are here to pleasure my soldiers and birth their young. You will not require such mighty tools for that purpose. But for now, they are yours.”

The bells in the distant clock-tower chimed, ringing out four lonely notes.

“You have an hour.”

With that, Nightmare Moon edged up into the air. She began to fly slowly upwards, beckoning for her student to follow her. Twilight noticed and eagerly followed her, before they both landed on a nearby balcony that overlooked the scene.

The moment they’d flown away, ponies had descended on Celestia. She tried desperately to bat them away, but it was no use. Soon she was overrun, the ponies clambering over her like cockroaches. The sensations around her crotch were incredibly uncomfortable, as two well-endowed ponies had suddenly pushed into her rear and vagina. There would be no time for her to ease into this torment, as the crowd knew what was at stake if they failed in their task.

Two muscular hooves gripped her head, before yanking her jaw open. Another took hold of her horn, holding her in place as the stallion guided his cock into her mouth. Now these three ponies were using her in tandem, thrusting into her body with reckless abandon. But as miserable as Celestia felt, she couldn’t find the inner strength to fight back, or even to struggle. The whole event just seemed unreal, incomprehensible. Celestia wouldn’t have been surprised if this was all some outlandish nightmare, but no. The searing pain cutting through her body reminded her of the reality of what was happening.

Fancy Pants was in love with the Princess’s warm, beckoning pussy. Again and again he hilted himself inside her, shuddering with longing each time his balls playfully slapped against her quaking body. Despite a soft chill on the air of this eternal night, the intense heat of Celestia’s vagina on his cock warmed him to his very core. He slumped forwards, coming to rest on Celestia’s body as he rocked his hips back and forth. He wanted nothing more than to look into the Princess’ eyes as he came, but alas, her face was entirely covered by the stallion that was using her throat. He instead found his eyes settling on the stallion’s pendulous ballsack, smacking against her chin so loudly that it could be heard over everypony’s grunts and moans.

The sound was hypnotic, and it rapidly drove him over the edge. With one final moan he let loose, a barrage of seed shooting into the Princess’ royal womb. He held himself inside her, his eyes rolling back as the orgasm slowed. Spent, he was about to step aside, when he felt two strong hooves come to rest on his shoulders. Suddenly he was being yanked backwards, his cock sliding free with an audible ‘pop’. Stumbling away he careened into the crowd, struggling to stay upright. Glancing over, the stallion that had pulled him aside had already pushed his way into Celestia, using Fancy Pant’s dripping sperm as lubricant. He sat where he’d fallen, watching as the pony buried deep in her throat came as well, pumping thick strings of seed down into her belly.

He was prepared for the next pony's violent approach, and spreading his wings, managed to dodge out of the way. Everypony was rushing to take their place inside the ex-royal.

Two had cum inside her. One hundred and ninety eight to go.

Twilight rested by her Master’s side as the chaos unfurled below, purring slightly.

“Master, why are you letting the crowd use her first? I thought you would have wanted the traitor all to yourself.”

Nightmare Moon mused on the question for a few seconds before answering.

“Well, you see young one, I want Sister to embrace the sensation of two-hundred cocks abusing her body. But then, once they are done, she is going to feel the sensations of my cock. That is when she’ll realize the true extent of my power, and her mind will snap. Being an alicorn, she is much more resistant to corruption than the average pony. I want my followers to lower her guard, if you will. Then I shall deliver her mind the killing blow.”

Twilight couldn’t help but look slightly disappointed at the Master’s plan.

“B-but, will my friends and I get to join you in that final moment? I don’t want to get left behind, Master…”

Nightmare Moon smiled, pushing Twilight under her body with her wing.

“Of course, I would never leave my most loyal of breeders out in the cold. But for now, why not warm me up for the games to come?”

Celestia screwed her eyes shut as an errant jet of spunk shot over her face, settling on her muzzle and eyelids. The futanari mare who’d unloaded it gasped in panic, her load having missed its target. She shot forwards, scooping up as much of the semen onto her hoof as she could. Before it could dry into her fur she shoved her hoof into the Princess’ mouth, forcing her to lick the seed away with her tongue.

The crowd was starting to get flustered. Time was passing quickly, and nowhere near the two-hundred had cum inside her yet. Her belly already sloshed audibly with each wobbling thrust, but it was nowhere near enough. Cheerilee watched, panic-stricken, from the edge of the crowd. She was next to take the Princess’ anus, but the stallion currently jammed inside her had an especially impressive stamina about him. It had felt like an age ago he’d clambered onto her abused behind, and yet he was still going as strong as ever. Various ponies had begun to yell and swear at him, but he wasn’t moving on. Cheerilee had to act now.

Striding forwards, she came to rest beside Big Macintosh. He was focused, and barely seemed to notice the mare approach. The Princess rested on her side, with Big Mac stood, his hooves wrapped around her outstretched hind-leg. Two other ponies were busily using her face and pussy, but they weren’t who Cheerilee was focused on. Sidling up besides Big Mac, he watched as she prodded Celestia's asshole with her cock. With his titanic length buried inside her, there wasn’t a chance she’d be able to break in as well, was there?

Teeth grit, Cheerilee pushed with all of her might. She closed out the sound of Celestia moaning in agony, the meaty cock in her mouth drowning out her anguish. Instead she just watched the mare’s ring as it slowly parted. Big Mac’s intense thrusts made the job especially difficult, but eventually, to Cheerilee’s immense satisfaction – Celestia’s defenses gave out, allowing her inside. The feeling was unreal as Cheerilee’s cock butted up against Big Mac’s. Grinding and butting against each other they dominated Celestia’s tight rear. Cheerilee could feel every vein in Big Mac’s cock as it rubbed past her own, and the sensation quickly drove her towards orgasm.

But it was actually Big Mac who came first. His motions had become stiff and awkward, until it all was too much. Thrusting forwards again, corrupt seed poured from his cock, painting Celestia’s innards white before rushing down into her belly. Cheerilee shuddered as she felt Big Mac come. His cock pulsed against hers, milking her even more tightly than before. The last thing Cheerilee noticed was just how hot her cock now was. Buried inside Celestia’s anus alongside Big Mac, the feeling had been incredible. But now every inch of her corrupted flesh was being coated in his hot load, until she could take it no more. Throwing her head back, Cheerilee began to cum as well, joining Big Mac in searing orgasms. The rush of spunk cascading down into Celestia’s belly had now doubled in strength as the ponies filled her in unison. She could hear and feel her gut groaning with the effort to keep it all in, her body filling with liquid faster than she could handle. Her stomach, already sloshing violently side to side, expanded even further in an effort to hold this latest load. Finally sated, the two ponies pulled free from her rear together. The gaping maw they left behind was impressive, Celestia’s anus twitching slightly as it attempted to recover. Not that it had any time to, as no sooner then they had pulled free another pony had stepped forwards to take their place.

And their double-teaming strategy had given everypony else the same idea. The stallion in her mouth was joined by a second, tussling by his side in an effort to get space. Eventually he moved the other over enough, and began to press his cock against her open mouth. Of course, with one cock already lodged deep inside her throat it was almost impossible to fit another inside. Frustrated, the stallion shoved his cock as far in as he could past her lips, before beginning to aggressively masturbate. The feeling of his hoof against his flesh - along with the second cock rubbing against his tip – would have to do. Struggling to take the whole mass of flesh, Celestia’s eyes widened as she felt a second cock effortlessly slide into her pussy. After being used by one and all there was little difficulty for a second pony to push their way inside. It was only when the inquisitive head of a third pony’s cock began to probe her that she grew truly scared.

The now huge crowd of ponies simultaneously using the Princess clamored and struggled against one another. With so many ponies stood around her holes it was difficult to find the space to work. Especially around her vagina, where three different ponies fought to fit themselves inside the Princess. A fourth pony approached, but they quickly shrunk away as one of the busy ponies threatened him.

At the back of the crowd, Lyra paced nervously back and forth. She glanced over towards the clock tower.

Twelve minutes. They only had ten minutes left, and there was still a group of ponies stood around waiting. There wasn’t a chance they would all be able to get to the front of the crowd and use the Princess in time. They would have to get drastic.

Lyra yelled for a few of the awaiting ponies to follow her. There had to be something in one of the nearby stores that could help, somehow.

A minute later they returned. They’d stumbled across a nearby wine store, and having raided the stock, pulled out several hefty wine casks. Levitating them down the street towards the crowd, they cracked off the lids, allowing the wine to pour out onto the streets. Arriving among the flustered spectators, they rested the barrels down on the floor, being careful not to damage the taps that jutted out near the base of the barrels. Lyra shouted for attention.

“EVERYPONY! If you haven’t used her yet, we don’t have time to lose! We only have ten minutes more to our window! Come here now!”

The remaining ponies edged over, worried to lose their place in the crowd beside the Princess. They watched as Lyra reared up onto her hind-legs, and began to hurriedly masturbate over the now open-topped barrel. The others quickly got the idea. With three barrels available, the ponies quickly gathered round, resting their lengths over the edge of the barrel. All to weary of the ticking clock, they started to work, desperate to draw seed.

It wasn’t long before the first pony came, launching a heavyset rope of sperm against the interior of the barrel. As the first went, others quickly followed suit, adding their loads to the growing collections. Walk over, cum, step away. Rinse and repeat. Eventually, the final pony shot their load into one of the barrels, gritting their teeth with the effort. Two minutes.

Lyra took the lead, grabbing one of the barrels in her magic. It took all of her effort, as the newfound weight was incredibly difficult to control. She could see semen sloshing over the sides as she wobbled over towards the Princess. The last of the ponies waiting to use Celestia had finished, and so now they resolved themselves to hold her in place, in case of an effort to escape. Though at this point, escape was nigh on impossible. The grotesque sight that was her belly easily pinned her in place.

Lyra was the first to arrive by the Princess’ side. It took all her concentration, but she managed to steady the barrel over Celestia’s mouth. Calling to one of the onlookers, a stallion dashed forwards and held Celestia’s mouth open. She waited for the other barrels to be positioned over her other holes, before lowering the tip of the tap into her mouth. Cautiously the others did the same, guiding the taps down into her awaiting holes. Ready, Lyra opened the tap, releasing the floodgate. The others quickly followed suit.

Celestia gagged as the torrent broke past her tonsils, flowing down into her belly. It wasn’t so much the sensation of it that scared her, it was the knowledge of how much was to come. The barrel floating over her head wasn’t small by any means, and as flecks of spunk sloshed over the edge, down onto her face, she was reminded just how full they were. This was going to be difficult to keep in.

She could feel her already tortured body begin to stretch even more as the constant, three-pronged attack assaulted her innards. Seed was pumping out of her pussy as fast as it flowed in, but she could feel herself slowly expanding even further. Her vision was now almost entirely obscured by her belly, the wobbling mound of flesh still growing outwards, inch by inch. Spunk dripped from her nostrils, running down her face and back into her open mouth.

The bells of the clock-tower finally chimed. Five times they rang out, before silencing again. Satisfied, Lyra withdrew the tap from Celestia’s mouth, before tossing it aside. The three barrels were left in a pile as Nightmare Moon descended upon the gathering. She barely made a sound as her hooves hit the ground. Wary of her approach, the exhausted ponies stepped aside, allowing the Master access to her prize.

The Princess laid face down on the ground. Her tantalizing rear was held slightly in the air by her bloated gut, which pressed down against the floor. Her distended body gurgled and rumbled as it tried to handle the monstrous load deposited within it. Her mane and tail were both sticky and crusting as the semen spattered across them dried in the cool night air. The skin around her mouth and genitals were disgusting, stained so deeply that the mess would certainly never come out. Even as Nightmare Moon watched, more semen flowed from her holes, the royal’s body unable to withstand the onslaught. The lake forming around her slowly expanded, until it began to wash teasingly against the hooves of the surrounding crowd. The Princess’ face was groggy and distant, as if she was barely even conscious. Evidently, she wouldn’t be going anywhere under her own volition. Nightmare Moon turned to address her followers instead.

“Citizens. You did well. Not only will you keep your lives, you have earned your place in my kingdom. But before you may have respite, one more task remains. The corruption process of the false Princess is not yet complete. You have done your part, but I must now do mine. Bring her to the throne room, so the corrupting ritual may be completed.”

And with that she spun on her hooves, swaggering into the castle. Twilight Sparkle bolted after her, and Applejack rolled her eyes as she watched. The ponies looked between one another, then down to Celestia. This was going to be difficult. Canterlot Castle had a lot of steps.

Twilight watched doggedly as Nightmare Moon spun around atop the castle throne. She hopped from hoof to hoof, unable to hold back her filly-like glee at the sight of her Master's glee. Waggling her rear excitedly, the alicorn took a deep breath as she sat down. The feeling was awe-inspiring, knowing that her guile had allowed her to steal the throne of a deity. She quickly shook this giddiness as she heard hoof-steps approaching. The throne-room doors flung open, through which emerged around thirty ponies. They were all grasping onto Celestia. Some gripped her limbs, some encased her in their magic, some were even struggling beneath her - the swollen alicorn resting on their backs. Taking a few steps into the throne-room they stopped, lurching forwards in an effort to dump the huge weight. Even with so many ponies working, that weight was too much.

Celestia crashed down in a heap. The sound of muffled cries wafted out from somewhere beneath her belly. Groaning with frustration, the ponies stepped forwards, using a gargantuan effort to lift her ungainly stomach. Out from underneath scrabbled Sweetie Belle.

“SWEETIE! What in our Master’s Equestria are you doing here?” Rarity was incandescent. She was already furious that the other mares had drank the potent dragon sperm from her holes while she was unconscious. Of course, her womb and belly weren’t going to be giving it all up, but the vast extent of that satisfying bulge was now gone. Now she just looked like some normal mare. And now, on top of that, her younger sister had sneaked out after her.

“I-I’m sorry sister! I’ve just felt so strange and confused since Ms. Twilight made me play with her weird stallion bits back in Ponyville, and when I saw everyone leaving for Canterlot I wanted to come along too! Please don’t be mad!”

Rarity’s anger eased, before it eventually disappeared entirely.

“It’s okay, darling. This is adult business, but I’m not cross. Here, come give your sister a kiss.”

Beaming at her sister’s forgiveness, Sweetie Belle leaned forwards to plant a kiss on her cheek. She yelped in surprise when Rarity lunged forwards, burying her tongue deep in her throat.

Nightmare Moon smiled at the sight of the two sisters rolling around on the floor. What a beautiful legion of followers she had. She cleared her throat to get everypony’s attention.

“Thank you for bringing me the degenerate. My closest followers and I must complete the ritual of corruption. Please, return to your homes, take the rest thou have earned. For once you awake, you will have a busy time cleaning the streets and repairing this cum-stained city. Work must be done after tonight's conflict, especially if we are to craft this city into one fit to raise my army. Go. Eat. Breed. Be merry. Twilight’s friends, however, I require you to stay.”

The gaggle of stallions and mares slowly trotted from the room, leaving only, Celestia and Nightmare Moon, along with Twilight and her friends – whom had sidled over to their Master’s side. The young mares were clearly excited for the Master to unveil the last stage of her plan, barely able to contain themselves. Their eyes darted between Master and Celestia, who had slowly begun to lift her head from the floor.

“…Sister, I know you are still in there, somewhere. Please, listen to me. You can fight this darkness. Please!”

The six eager mares stared up at Nightmare Moon, waiting for a retort.

“Celestia, you don’t seem to understand. Luna is dead. And you killed her. A scared, vulnerable alicorn lashes out in a cry for help, and you respond by imprisoning her on the moon for a thousand years, without a hope of repentance? No company, no hope. And not content, you gave me these genitals, and encased them in iron in an effort to spite me. But perhaps the saddest part of all of this is that you expected that pony to seek redemption from you. The prisoner, seeking redemption from her torturer. No. The balance of power has tipped eternally in my favor, and you are going to suffer, so, so much.”

“…Then you leave me no choice…”

Celestia spoke with steely resolve, the tone of a desperate pony. A pony that had been through hell, but knew it could only grow darker. She trained her horn on Nightmare Moon, and before any of her followers could respond, she drained the last of her strength, conjuring a bolt of pure energy. It launched from her horn, sailing through the air towards Nightmare Moon. Twilight yelled out in horror as the sparking, crackling bolt of yellow magic catapulted across the room. She prepared to dive into its path, but she knew she wouldn’t be able to reach it in time. The bolt connected with Nightmare Moon’s face.

The bolt exploded into sparks, flying out in all directions and raining down onto the floor.

Pinkie Pie peered over her hooves, scouring the throne for her wounded Master.

Nightmare Moon was still sat atop her throne, as if nothing had happened. She wiped some of the residual energy from her face, before lowering herself onto all fours.

“Really? And I thought you couldn’t be any further humiliated after the peasantry finished abusing your body. Your body is already surging with my corruption, did you honestly think you would still have the mental capacity to conjure a killing spell? Please.”

Celestia struggled to recall Moondancer’s warning. The corruption was spread through the seed. And with the amount of seed in her belly and womb, the level of corruption inside her must have been toxic.

“Of course, the pauper’s seed was never going to be quite enough to corrupt an alicorn as powerful as you, regardless of the amount that’s already coated your innards. But their corruption has managed to lower your defences, as it were. And that’s why we are here. To finish you off.”

She beckoned for Twilight and her friends to join her at her side.

“Sister. Unbound my shackles.”

Quaking intensely, Celestia’s horn slowly began to glow. The magical energy engulfed the shackle, and began work undoing the spell she had cast upon it one thousand years ago. Progress was slow, her concentration wavering as she quietly sobbed. Eventually though, it was done, and it clattered to the floor with a satisfying thud.

Free at last, Nightmare Moon could barely contain herself.

“Good. Now, sit still. Hold your head up high, for goodness sake. You’re in the presence of royalty now.”

Begrudgingly she did so. Nightmare Moon took hold of the loosened shackle in her magic grasp, and floated it around Celestia’s neck. Clicking softly into place, she pointed her horn at the cast-iron ring. It glowed for a second, before the energy shrank into the metal. Now it was locked again, this time bore by a pony that deserved it.

The shackle was incredibly tight around Celestia’s neck, causing her massive discomfort. Whenever she tried to turn her head she could feel it chafe slightly, so she quickly learned to keep as still as possible. One thing that was entirely overpowering was the smell that clung to the iron. Having been bound to Nightmare Moon’s member for a thousand years without a single clean, the disgusting smell was practically intoxicating.

“Good. You look beautiful in it. Like a fine piece of jewellery.”

As an after-thought, Nightmare Moon summoned forth a small padlock. Imbued with powerful corrupted magic, she clasped it in place around her slave’s horn. Now there was no chance of her casting any spells. Even if her mental energy was completely drained, why take the risk?

“Now, stand up and walk to the throne for me.”

Nightmare Moon and her followers stood aside, watching for Celestia to obey the instruction. She wheezed loudly, struggling to lift her incredible weight. She managed several steps before collapsing to the floor again, exhausted.

“Very well. It is evident, ladies, that the alicorn lacks the strength to carry on. I guess we will just have to break her where she rests.”

And with that, the group stepped forwards. This was it.

Nightmare Moon approached the fallen Princess’ face first. She hovered over her for a second, playfully running her hoof along the back of her ear. But she could see that Celestia was looking straight past her, focused on that demonic cock instead. She had reason to be fearful – her gargantuan cock was twitching excitedly, bouncing slightly from side to side. Her balls too looked terrifying, comparable to nothing Celestia had ever seen before. She shuddered as her sister stepped forwards, until the tip of her appendage rubbed against her chin.

She knew not to fight. She couldn’t conjure up the strength to do so, and she could barely move. All efforts to beg – like an animal – had fallen on deaf ears. Showing resistance now would only result in further misery for her. She didn’t wait for Nightmare Moon’s instruction.

Slowly she opened her mouth, lolling her tongue. The hunk of flesh pushed past her lips, dragging past her tonsils as it slid into her throat. A short moment later she felt a cock prodding her labia, along with another against her anus. The two ponies behind her moaned in unison, and from the tone of their voices, she guessed it was Twilight and Fluttershy.

Twilight watched her cock slide into her old teacher’s anus with a satisfying ease. The brutal raping earlier had left her body rather ‘accepting’ for future lovers. As she settled in place, she watched Fluttershy slowly slide her dual cocks into the slave’s pussy. She moved carefully, nervous to go too quickly. She didn't want to cum before Master allowed it.

Twilight carefully positioned herself atop Celestia’s rear, trying to get space around Fluttershy. Finally comfortable, the two joined their Master in action.

Celestia choked back tears as her sister’s crotch smacked into her face repeatedly. The worst part was the intense pain that germinated in her throat. In most situations, a pony’s throat would distend and expand in an effort to accommodate the foreign body. But with the solid shackle bound around her neck, her throat was unable to expand. As a result, every time the cock slid downwards, it butted against the metal ring. But instead of stopping at this blockage, Nightmare Moon would just push past, moaning with the pleasure of her sister's crushing tightness.

Scanning the throne-room, Nightmare Moon settled her eyes on the rest of her followers. Tragic that Celestia only had three holes. It left the others rather out of the loop.

Applejack, Rainbow and Pinkie Pie had found a way to keep themselves entertained, though. Rarity had straddled Applejack, lowering her pussy down onto her majestic, corrupt cock. Pinkie Pie, not content to be left out of the fun and games, positioned her anus over the earth-pony’s muzzle, sighing loudly as it parted around her mouth. The warm, moist tongue probing her anus was beautiful. Only Rainbow Dash had no place. Her face betrayed her disappointment as she watched the others having fun together. She settled on the floor and began to masturbate, although it was apparent she wasn’t enjoying it.

Nightmare Moon watched the scene unfold as she battered her sister’s face. They looked like they were having fun, but she could help them have more. Besides, they’d earned it, helping overthrow the city.

Closing her eyes, she took a deep breath as the tip of her tail began to solidify. Slowly it transformed from its soft, vapor-like state, into a thick, writhing tentacle. Twilight gazed over at them as they sidled along the floor towards their targets. She couldn’t understand how Master created them, but the details didn’t matter. She could remember how good they felt.

Rarity’s eyes widened as she felt something rub against her anus. Bouncing up and down atop Applejack, she arced her head around to see. It was a strange, light blue tentacle. Before she had time to react it pushed into her, past her colon. She could feel it inside her, hefty and muscular, despite being pure energy, and not a physical beast. It inched further and further upwards, stretching out her lower intestine. It had to stop eventually, surely? But no, it kept going, stretching out more and more of her internal organs. It didn’t move quickly, and it didn’t thrust, it just kept going. Suddenly her stomach started to churn. Her digestive juices sloshed around violently, as the tip of the tentacle pushed through. Upwards it probed, into her esophagus.

Pinkie Pie watched, confused, as the white unicorn opposite her suddenly froze, stock still. She’d noticed the tentacle slither into her rear, but she had no idea of the distance it had traveled. But suddenly the mare’s jaw flung open, and the round-tipped tentacle popped free. It waved around in the air for a few seconds, before making a beeline for Pinkie Pie’s mouth, hanging open, agog. It shot into her, descending to her core.

Applejack’s vision was entirely dark. With Pinkie Pie’s soft buttocks resting atop her face, she could see none of the bizarre occurrences happening to her friends. She was just focused on Pinkie’s anus as her tongue ran against its walls and the sensations of Rarity's soft folds. That was when she felt a warm, solid mass pushing past her tongue. Before she had time to object, the tentacle had punched past Pinkie’s colon, bursting out, directly into Applejack’s mouth.

Rainbow Dash had watched the tentacle slither over the throne-room floor towards them. She’d been full of excitement as it approached. Sure, it was slightly disappointing for it to probe straight into Rarity’s asshole, but she knew it would emerge elsewhere. Again, sadly it went to Pinkie after that. And then to AJ. But Rainbow knew it would emerge from the orange mare’s ass soon. She just had to wait. She span round, waving her ass in the air, ready for it.

Nightmare Moon could feel her orgasm building. She’d waited for the chance to rape her sister for so many hundreds of years now, she could barely believe it was actually happening. But she wasn’t going to waste her orgasm in the alicorn’s throat. Of course not. Her seed was going straight to the mare’s womb. Slowly withdrawing, she watched as her sister spluttered desperately for air. Her whole body shuddered as the two mares behind her continued plowing her.

Striding around the alicorn, Nightmare’s tail began to retract as she moved. Applejack could feel it reverting through her innards, before it popped free of her body entirely. Soon it had been tugged free of all three of the mares, flopping down onto the floor.

Nightmare Moon moved around Celestia, hovering beside Twilight and Fluttershy. Clearing her throat, the two mares quickly yanked themselves free, graciously stepping aside.

“You’re good mares. Twilight, why not make use of her face while it’s free? I want my most promising student to be the one to help snuff out the sun. As for you, Fluttershy. I’d say that Rainbow Dash is a rather pathetic spectacle. A strong broodmare like her needs. Change that for me. Use and abuse her, and make her the mother of your foals. Cum quickly for your Master. Cum hard.”

Eager to please, the mares moved into their positions. Twilight sat in front of Celestia’s face, staring deep into her eyes as she moved her head down onto her shaft. Rainbow, who had meekly rested her head down on the floor jerked upright as two cocks prodded her pussy and asshole. Stood behind her was Fluttershy, her warm smile deeply relaxing.

Meanwhile, Pinkie, Rarity and AJ were transfixed by Nightmare Moon’s tentacle tail. The single, thick tip that had simultaneously probed all three of them had morphed. Tearing itself apart, the head split into multiple forms, looking reminiscent of a cat-o-nine-tails. These newly formed tentacles surged forwards, burying themselves in the mares. Rarity was awash with bliss as one quickly punched past her cervix, while AJ took one down her throat. It was Pinkie that took the biggest brunt, though. Three tentacles approached her, slowly pushing into each of her holes, settling into a slow and steady rhythm inside her. Nightmare Moon was making her tentacles work quickly. She was ready to cum, and she wanted them all to go together.

She settled behind her sister’s enticing pussy. The seed had stopped spilling out with such ferocity, but it still dripped invitingly down her leg. She rested her fore-hooves by either side of the alicorn, before lining up the tip of her cock with the warm, wet hole. Every inch of her body was screaming for release, and it was about to come.

She soaked in the sounds of lust around her. The slapping of flesh on flesh as Fluttershy’s four hefty balls bounced off of Rainbow Dash’s rear with each thrust. The soft moans as her tentacles filled the three mares behind her with yet more of her warm corruption. And the wet squishing sounds as her vast cock broke into her sister’s pussy. Finally.

Suddenly everyone was in action. Fueled by lust and desperate to cum for the Master, the ponies were a blur. Fluttershy had already started to launch thick globs of pre-cum into Rainbow Dash, who moaned loudly as her belly began to sink towards the ground.

Twilight had both her hooves wrapped around Celestia’s horn, using it to pull her head up and down along her shaft. Slick with Celestia’s saliva and Twilight’s pre-cum, moonlight glinted from Twilight’s cock.

Celestia had begun to cry her eyes out again, but that didn’t matter. Only one thought occupied Nightmare Moon’s mind.

“Oh, my, this is it, isn’t it Sister? I’m inside your pussy, at long last. After all this time, it’s really happening. It’s really happening! I can feel you in every inch of my cock, and it’s better than I could have ever dreamed! I-I’m about to break through your cervix, cum inside you, and turn you into my hungry breeding slave! A thousand years of dreaming! A thousand years of dreaming… T-Thank you for trapping me on the moon, Sister. Thank you for filling me with this hate. Thank you for giving me these genitals. Without you doing all of that, I’d never have been able to make you mine… I, I…”

Her rambling train of thought broke down rapidly as her balls began to churn. The end.

Jerking forwards, she flopped down over Celestia’s body. Her cock began to spasm wildly, before the spunk began to rocket free of her. Unable to control herself, she screamed out in lust-fueled desire.

As she began to cum, so too did her tentacle tails, pumping thick, hot seed into the three mares. Rarity felt it rush past her cervix, into her womb, settling among the potent dragon semen that already soaked inside her. Pinkie Pie, stuffed with the most tentacles of the three, began to expand at an alarming rate. Her belly quickly sank, coming to rest on the warm floor. From there it kept growing, pushing Pinkie upwards in response.

As the sounds of her friends orgasms filled Fluttershy’s ears, she was unable to hold off either. She yelled with the effort, her quad balls beginning to spasm and shake violently. Her love poured into both Rainbow Dash’s womb and stomach, quickly reducing her to a babbling mess.

Celestia’s eyes stopped watering as she felt her sister orgasm. Suddenly, she didn’t feel any emotion. No fear, no sadness. She couldn’t work out why, but it was as if she’d just become a blank canvas. All that remained was a small, niggling voice, desperately screaming in the back of her mind. But it was gone in seconds, leaving her brain completely void. No memories, no comprehension. Nothing. She barely noticed the hot stream of seed launch from Twilight’s cock down her throat. As far as Celestia was now concerned, that was just something that was supposed to happen. But as seed continued to pump from her sister’s cock into her womb, new thoughts began to occupy her mind. Thoughts of cock. Thoughts of Master. Thoughts of foals. Thousands of them. And the thoughts were good.

The thoughts were right. She couldn’t comprehend quite what was happening. But whatever it was, it was what she was born to do.
