Luna's Lunacy

Nightmare stood in the center of the outdoor stage, admiring the sight of the six heroes hanging from their pikes. The remaining shadow bolts had just been tossed off the back of the stage and left there, not that their smell was anything compared to the maggoty flesh on some of the spikes.

One of her guards stood before her, eyes locked on her and trying not to breathe too much. When she looked down at him, he shook furiously. It made her smile.

"Have Cadence and Shining brought out and make sure we have a crowd to watch." Nightmare told him, "Anypony that refuses to come when asked is to be killed on the spot and dragged out into the street to rot there."

"Y-yes Princess."

"Goddess."

"Y-yes Goddess."

Corona landed besides Nightmare, making the guard jump, and walks around her sister, trailing her tail along Nightmare's backside in a flirtatious manner before moving to her other side to face the guard. She was shivering in anticipation herself.

"Patience sister," Nightmare said, "I want to do this with an audience."

"Pri-- Goddess!" another guard suddenly landing besides the first one, a pegasus with a panicked look in his eyes. He was panting as if he had flown here at top speed.

"What is it?" Nightmare sounded impatient.

"Changlings!' the guard panted, "They're attacking Ponyville. Several dozen of them at least!"

"What?" Nightmare quirked one ear, "Oh for the... if I have to postpone the execution... is Chyrsalis amongst them?"

"No, my goddess," he answered, "She's nowhere to be seen, unless she's being somepony else."

Nightmare sighed, turning to her sister, "Go take care of it."

"I don't want to miss the execution," Corona complained.

"So you'll have to hurry then, won't you?"

Corona narrowed her eyes, but didn't dare to question her sister any more. Her horn glowed brightly, causing the guards to flinch and look away, and she flashed away in a surge of teleportation magic.

***

Corona flashed into existence in the middle of Ponyville Square. She was fully charged up and ready to wreck havoc. She wasn't there to play or torture; she was there to kill as efficiently as possible so that she could get back to the main event.

There were several dozen changlings here, surprisingly all hovering around the town square themselves. It was surprising to find that they hadn't been preparing for this sort of contingency, but such creatures had never been very bright individually. They rapidly became aware of Corona's presence as the one nearest to her exploded in a rain of guts and bone shards, then the next one the same.

At this point the remaining one's attempted to fly outwards, but were all caught up in a sudden torrent of wind that encircled the main square, keeping any of them from leaving it. The wind picked up and soon they were being tossed about freely, unable to control themselves as the large tornado spun them repeatedly around Corona. There were civilians out as well, the ones that the changlings had been feeding upon, but Corona didn't care to differentiate.

Every pony that had been in the square was shot out of the tornado one at a time, a blast of Corona's energy blowing them out of the storm and spraying their guts across the town square. Soon there was a red star painted on the ground, centered around Corona as the winds died down.

"Ha! What in Equestria were they thinking," Corona huffed. The resistance had been almost disappointing.

"You've become a lot more efficient," a familiar voice called out from behind her.

No. It can't be. Corona arched an eyebrow and turned around.

She was just in time to get a face full of incoming energy. Corona was unable to see for certain who had leveled it at her, but whoever it was knew what they were doing. As soon as she magicked up a shield in front of her, then energy looped around her and slammed down into the square of her back instead. A normal pony might have been killed by that hit alone.

Corona fired a burst of energy in return towards the figure through the cloud of dust that still remained from her changling slaughter, only to have the figure blink out of existence. Not only that, but there was a magical glow that opened up in the path of the energy, the energy itself sucked through a teleportation field and slamming into her right side, seering against her wing and knocking her over to the side. Her own blast hurt far more than the initial hit from her enemy.

"You are stronger than me," the voice said, "But I've always been more creative." There was no doubt now whose voice it was.

"How are you alive?" Corona cried out, eyes and magic searching for where they were now, "We killed you!"

"No," Twilight responded, "You killed Runner Up. It was a good thing you gave me a changling to study like that. By invading his mind I learned how to lock him into a form so firmly that he believed it himself. You only thought you stopped me from teleporting away. I did a bait and switch and gave you him instead. Oh, and as an added bonus I managed to take control of one of the smaller changling hives. You sure used up a lot of your energy to take pot shots at them."

Corona finally spotted Twilight, hiding behind a wall of magic that was deflecting light and acting as a cloaking field. This time she surged herself upwards as soon as she fired the magic, dodging the burst of energy when Twilight tried the same thing again. This time Corona's magic was locked onto her, and Twilight found that repeated teleports were not shaking it.

Twilight had thought of everything though, and Corona was suddenly weighted down by the size of the unicorn when Twilight appeared on her back. Twilight grabbed both of Corona's wings suddenly, using them as a shield against the incoming magic. The magic burned into the same wing that had been hit before, this time seering most of the wing clean off. Twilight was struck as well, but as she was blasted back she grabbed hold of Corona's other wing with her hooves, cracking it out of joint from momentum before losing her grip and rolling across the square through the assorted pony and changling guts.

"I... knew she'd send you." Twilight staggered to her feet, her image disappearing behind a wall of magic once again, "I just had to time it just before the sceheduled execution. I knew she wouldn't want to postpone it. It's a good thing you're all so predictable, I don't know if I could have beaten her. With you, I have an advantage."

"You're a fool!" Corona screamed out in rage, trying to find Twilight again as she moved about. The seering pain in her wings was distracting, and she strained to keep a shield up on all sides this time. This slowed her alicorn regeneration to a crawl, however, not to mention made it harder for her to reach outside the bubble to find Twilight with her magic.

"You see," Twilight went on to explain, "You're not as far gone as Nightmare, so you're hesitating before most everything you do. Most ponies probably wouldn't notice, but it's enough for me to counter."

"Bullshit," Corona almost laughed, "You're my faithful student, you'll hesitate as well. You won't kill me."

"I won't?" Twilight's voice seemed to come from several directions at once, "I'm more far gone than you give me credit for."

There was another surge of energy from behind Corona, one that was easily blocked as she was holding up her force bubble on all sides now. It didn't even seem to have been trying, in fact. Another burst came from another direction, followed by another still. About a dozen in all, each made a different hum as they glanced against the force bubble.

"There! Got it." Twilight's voice shouted triumphantly.

Corona chuckled, "Oh really? And what do you have, faithful student."

"Oh simple," Twilight may have been a good guy, but she had a bad habit of explaining everything she did, the same as any villain would. "I wasn't attacking you, I was deflecting different types of energy against you, then measuring how they deflected. Now I know your shield frequency!"

And with that, there was another burst of energy just above Corona, inside of her shield. Suddenly Twilight was on her back, wrapping all fours around her. Twilight curled her hind legs about Corona's injured wings, making sure to put pressure on them. She bent her head down, placing her horn directly against Corona's and letting out a burst of energy. Using the direct contact of horns as a conductor, the energy blasted directly into Corona's brain. For a moment Corona felt like her brain was going to boil.

Corona managed to get a teleportation spell of her own off, blinking out from beneath Twilight and leaving the unicorn to fall to the ground, stumbling to keep standing. Twilight wasted no time before putting up her cloak on all sides, but when she spotted Corona, it wasn't clear if she had to.

Corona was staggering now herself, trying hard to remain standing. Her horn glowed several times as she tried to raise her shield again at a different frequency, but each time only resulted in a horrible pain jerking through her head. She felt like her eyes were boiling in their sockets. She could barely think. The blast to her horn combined with the use of her own usual frequency was as direct a hit as any unicorn could possibly make against another.

Corona felt herself floating quite suddenly, opening her eyes and suddenly realizing that she had been teleported several feet off the ground. She fell back downward, only to be teleported again, about twice as high this time. Her wings instinctively tried to carry her as this sequence was repeated time and again, but they couldn't even slow her fall.

"And you'll reach terminal velocity about.... now," Twilight said.

With those words, the portals disappeared and Corona slammed down onto the ground. She tried to brace herself with her legs, which only resulted in all four snapping. The bones in her legs shattered from the impact, bloody shards of bone jabbing out of her flesh as the limbs wadded up beneath her. Even her regeneration would have trouble with such an injury; it would be like putting together a jigsaw puzzle.

Corona's scream made Twilight take a deep breath, and at this point she realized precisely how wet she had become. Her legs shivered as she dropped her cloak and limped towards her mentor. Corona's horn flashed, but she was not used to operating with these kinds of injuries.

Finally, Corona's form shimmered, her possessed mind receding from the pain and allowing her to break free from the control. When Twilight stood in front of the alicorn's head, she looked down at Celestia instead of Corona.

"Twi-- light," Celestia groaned, "Help me-"

"Hello Princess," Twilight recognized the change, but didn't stop. She crawled back up onto Celestia's back, holding her fore legs around Celestia's neck as she placed her horn against that of her mentor. Her hind legs gripped about Celestia's back, her hips thrusting slowly against her from excitement, leaving a moist streak about the center of her back.

"Twilight you don't have to do this," Celestia panted, "I'm back, please help me."

"Oh I know," Twilight said, "But that doesn't change the fact that you're too weak to beat Nightmare, and I can only beat Nightmare if I have more power."

Celestia didn't have time to answer before the surge of power shot down her horn again. It dug around all sides, and her magic yanked the horn upwards. By this point Celestia was already pretty fried, most of the nerves attached to the horn snapping immediately. Twilight gave it another hard twist, and it separated. There went any hope of regenerating.

"You know, Princess," Twilight casually talked as she did this, "In order to keep Runner Up in that form, I had to keep my mind inside his. I felt everything you did to him as if it were happening to me."

"I'm so sorry," Celestia's face was streaked with tears and not just from her own agony. Blood drooled down her face as well, both from the new wound on top of her head and from her eyes themselves, "Twilight please."

"Shut up," Twilight said, "You're not going to ruin this moment for me by suddenly being 'cured'."

Twilight admired the long horn of her mentor for a moment, smiling to herself, "I'll probably need this to open some of the doors inside the castle. You did love those phallic locks." She leaned forward to lick at the wound on Celestia's head, "But there's no reason we can't play with it first is there?"

The horn was shaken in front of Celestia's face teasingly, before moving back slowly. It glided against Celestia's flank, pushing into the flesh there and slowly crossing out her cutie mark by cutting deeply, leaving a bleeding x mark on first one and then the other.

"Twilight," Celestia groaned, "I know you're angry but... Twilight please."

"It must be strange for you," Twilight mused, "To look down the barrel at death after not fearing it for so long. Oh you should have never given me full access to the Canterlot Archives.."

"Twilight doing this will not bring your friends back," Celestia flinched as she felt the horn dragged down beneath her tail, tracing up and down between her tailhole and the royal cunt. The horn was pressed into the later, spreading out her lips as the tapered end entered and then pushed her wider towards the base. Twilight just left it there, slowly stroking in and out, it's rough surface now coated with cunt juice.

"Oh shut up," Twilight said, "Do you really think we're just going to forgive you after all the ponies you've helped kill for no reason at all? Never again."

Celestia panted as Twilight slid off of her back, then grabbed hold of her remaining wing to begin to twist it. Celestia groaned out in pain as the second wing was also pried off of her, turning the all powerful goddess into a lowly earth pony. The horn in her cunt continued to thrust of it's own accord, going deeper and faster with each stroke, practically stabbing itself into her. When it hit the door to her womb, it immediately pressed through and invaded her. Celestia tried hard not to tremble too much, knowing that if she moved her hindquarters, then horn would end up stabbing her rather than just brutally raping her.

Twilight tossed the wing off to the side, then moved around to Celestia's head. She picked up her head with one fore hoof, then pressed her lips against her mentor's, kissing her deeply, shoving her tongue inside and teasing against her jaws and throat, "Oh Celestia... I've wanted to do this for so long." It wasn't clear if she meant the killing or the fucking.

"Twilight, is there anything I can do? Anything at all?" Celestia panted out as Twilight pulled away from the kiss, drool still connecting their lips.

"Mmm, you can lick me out like a proper little slut, 'teacher'." Twilight breathed out as she lay on her backside and scooted her purple plot up to Celestia's head, "Between licks tell me how much you deserve this, and how you'll give anything to be my little fuck puppet forever."

Celestia choked slightly as she found her nose inches from Twilight's cunt, and looked up at her as if to see if she was really serious. Twilight licked her lips in return, spreading her legs out further and pushing her visibly drenched funhole towards her. Celestia took a deep breath, and began to lick, tracing her tongue up and down the lips, then nibbling gently at Twilight's clit before pressing her lips more firmly and pushing her tongue inside to feel of every muscle within.

"I... deserve everything... my actions... were inexcusable... but... but if you keep me... I'll be your fuck slave forever... I swear it... I'll do anything you wish... you can... you can parade me around... and let everypony that wants to rape me... so everyone will know.... that I'm a worthless... cock loving... cunt worshiping... piece of fuck meat."

Of course the horn was still raping her juicy cunt as well, blood and fuck juice drooling down her thighs as it continued its assault. When the thing suddenly yanked free, Celestia cringed, thinking it might just start stabbing her, but its stab landed it in her other hole instead. This made her squeal against Twilight's pussy, making it all the more enjoyable for her. The horn began to rape into Celestia's asshole just as rapidly, causing her to squeal each time she attempted to continue her slutty speech.

Twilight just lay on her back, relaxing, all fours sprawled out. She enjoyed the feeling of the sun beating down warmly upon her even as the goddess of the sun ate her out and begged for the privilege of being her sex slave. She rolled her eyes back as Celestia's ranting devolved into squealing, sending beautiful slivers of pleasure up through her body. She didn't care who saw her doing this out in public, in fact she hoped that all her remaining Ponyville friends were watching out their windows.

Finally she felt herself go over the edge, spraying Celestia's face with juice, covering it with a sheen of purple-shaded clear liquid as she rubbed her pussy enthusiastically all over her former mentor's face. She looked up between her legs, watching Celestia as she pulled her head away, drooling with her juice and holding an abstract look of humiliation in her eyes.

Twilight laughed at this, her best psychotic laugh yet, as she sat back up to her haunches, "Oh this is just perfect. Nightmare Moon is probably waiting for you to return. You had one job, Princess, and just look how badly you fucked it up. Just like you fucked up by not letting us execute Luna as soon as we took her powers. Just like you fucked up by not seeing it was her sooner. Come to think of it, I don't think you've ever been useful no matter who was attacking."

Twilight walked around her as she talked, and Celestia didn't bother following her with her gaze. She just looked down at the ground, mouth still drooling with saliva and juice, her face twitching with each ram of the horn into her ass. She just waited to see what Twilight would do with her.

Twilight's horn glowed, and she shifted her own form. She didn't deprive herself of her female bits, but just added male bits in addition to make herself a full herm. The horn was yanked out of Celestia's bleeding ass, Twilight turned it about to the blunt side, using hir magic to round it off to a smooth edge on the base. Hir cock grew as it spilled out of the sheath, growing solid quickly beneath hir.

"Beg for the honor of being raped by Queen Twilight Acorna Sparkle," Twilight smirked. "Loudly."

"I..." Celestia obeyed, raising her voice, "Please Queen Sparkle... give... give me the honor of being your rape puppet! .. I... I'll be your dirty cum rag forever... I want to have your foals... then I want to watch you rape them to death because I'm unworthy of having your children!"

"Oh nice initiative," Twilight smirked, "You're getting creative." Twilight rolled Celestia over with hir magic, Celestia's legs flopping about, bleeding masses that could barely be identified as legs any more. Shi pushed them out of the way, then pulled hirself up onto her body. Hir throbbing shaft smacked against Celestia's red-stained belly, then shi moved the blunt end of Celestia's horn to hir pussy from behind.

Twilight pressed hir tip against Celestia, pressing inward easily with as much use as Celestia's cunt had had lately. The thick shaft pushed through the bloody chasm, grinding against the torn walls of Celestia's tunnel as it made itself all the way into her womb, pushing the tip inside as Twilight rolled hir eyes back. Shi went in all the way, hir belly pressed firmly against Celestia's and hir balls resting against the royal plot. Shi then pushed the rounded back tip of Celestia's horn against hir own cunt. When shi pulled back, it pressed inside of hir, stretching hir out just enough to be pleasurable, then shi forced herself back forward with a slam, making Celestia jerk with each movement.

Celestia continued to beg, calling herself a cum dumpster, a fuck meat factory, and everything else she could conceive of, but Twilight was enjoying hirself too much to even notice it. Shi rammed her throbbing organ into Celestia repeatedly, splattering pre all over her wounded insides in the process. The horn fucked hir from behind at the same time, hir pussy clenching down on it to make it a tighter fit, hir cunt so sopping wet that its rough texture didn't even bother hir. Within minutes she was busting a nut inside Celestia, pouring hir juicy sperm into Celestia's womb. For a moment, shi was tempted to take Celestia up on her offer of being a fuck toy factory.

No, shi had better things to do with her.

Shi pulled hir shaft out, allowing Celestia's cunt to drool again, then yanked the horn out of hir own cunt even as it still throbbed orgasmically around it. Shi turned the hown around, jamming it point first back into Celestia's cunt. Celestia jerked in agony, and then grew wide-eyed as Twilight put hir cock tip against the blunt end, preparing to fuck it in deeper.

"W-wait... I can't regenerate, that might kill me," Celestia said.

Twilight laughed, "Did I ever say I had changed my mind? You asked if there was anything you could do, not if there was anything you could do to save your miserable life. You should be more specific, next time. Oh wait. I guess there won't be a next time."

With that, Twilight slammed hir hips forward once again, jamming Celestia's horn far enough to protrude through the back of her womb and right into one of her lungs. Twilight groaned out as Celestia's body started to spasm, shivering in delight at the pain she must be experiencing. Shi continued to pound the royal pussy, pulverizing the lung as the horn was driven further up.

Celestia started to gag rather than speak, blood fountaining out of her mouth with each attempt to breathe. Twilight stretched hirself upwards, pulling Celestia's head down as well, and kissed her deeply, lapping into her throat to drink the blood that had begun to puddle there. Hir whole body shook in delight at what she was doing, that psychotic grin never leaving her face, forcing Celestia to stare into the insane eyes of her student as she was butchered from the inside.

Twilight pressed hard into Celestia's cunt, arching hir back and crying out in bliss as hir fuck spire blew its top once again. She flooded the lung with spunk and Celestia's next gag was more a fountain of cum than of blood. Twilight lapped the puddle clean once again, then cackled madly.

"Oh I want to impale your heart, but I can't let your soul get away, now can I?" Twilight asked, though Celestia was having trouble answering.

Twilight pressed hir body against Celestia's, belly to belly and chest to chest. Shi pushed her cock deeply once again, slowly twitching hir hips to stroke in and out a few inches, but far slower than before. Shi licked at Celestia's throat, then rolled hir eyes back before they became solid with power. Energy streamed out of Twilight's every pour, tentacles of power slithering across Celestia's form and entering through every orifice. Into her cunt, down her throat, into her ears, and into every single pore as well, Celestia's body was flooded with energy.

But it wasn't just any energy. Twilight's body trembled, went limp, and then Celestia felt Twilight's heart stop beating in her chest. At this point she knew what was happening. Twilight had shoved her very soul into her mentor's body, and was wrapping it around Celestia's soul within her.

"How... how did you learn to... how did you find this spell..." Celestia gargled out before her mouth was too full of blood to speak again.

"You should have never given me full access, did you think I wouldn't look at the forbidden archives?" Celestia heard the voice booming inside her head, her own mouth now moving as if to form the same words.

Twilight's soul compressed around Celestia's weakened spirit, and began to pry little chunks of energy away. It was as if Celestia's very essence was being dissolved in an acid bath, each nibble more excruciating than the last. They churned together, Celestia's form spasming violently now, the body of Twilight, now a corpse for all intensive purposes, flopping about comically atop her as it was still attached by the shaft.

"Oh fuck oh fuck oh fuck," Celestia tried to fight back, "No Twilight. Don't send me to oblivion." there was nothing more terrifying to the immortal goddess than simply not existing at all.

"You have no idea how hot this is making me," Twilight responded, "You are mine Celestia, in every conceivable way."

Celestia's spirit tried to push outward, but she was far too weakened. Not just by physical trauma, but by emotional defeat. She might have been able to resist and force a simple death had it not been for all the guilt that weighed her down. Twilight delighted with each squeeze, each pulse of resistance, and began to send strands of energy into Celestia as her soul slowly broke apart that of her mentor, absorbing it into her own.

Celestia's body began to bloat up as if suddenly every organ were inflated with hot air. It even rose up off the ground a few feet, pulling Twlight's corpse along with it. There was an earth shattering burst of energy, blasting a crater into the ground beneath them no less than five feet deep, and then a single body fell back to the ground with a thud.

Twilight blinked her eyes open, rolling herself about and straining to stand up. Her energy quickly returned to her, and she found herself standing at the bottom of the crater, her energy reserves suddenly feeling full again. No, they were overflowing. She had never felt this powerful before. Her horn flashed in the bright sunlight, the energy of the sun seeming to drive her even higher. She flexed out her powerful back, and two beautiful purple wings spread out. Celestia's horn fell onto the ground in front of her, but it glowed momentarily as Twilight teleported it to safe keeping.

Celestia's soul was still simmering within her. She knew from her reading that Celestia would take several hundred years to fade completely, and every second of that would be spent in unimaginable torment. It was a necessary evil. And besides it was fun to think about.

"I'm coming for you, Nightmare." Twilight took a single flap of her wings, the newly minted alicorn teleporting away in a brilliant flash.
