Strictly speaking, Luna wasn’t supposed to see into her sister’s dreams.
While surveying the dreamscape and keeping order in the minds of her subjects was part of the Princess of the Night’s duties, Luna and Celestia had agreed that Celestia’s dreams were off-limits. It was mostly to respect Celestia’s privacy, a privacy that was very often invaded by the press and media. Another reason, one unspoken yet understood by both sisters, was due to the content of Celestia’s dreams, or, more specifically, her nightmares. Neither Celestia nor Luna brought it up, but they both knew that Celestia’s subconscious was likely to conjure up images of Nightmare Moon, of their battle and Luna’s banishment. Something neither of them wanted to share with one another.
The week before Celestia’s birthday, her 3,000th year walking Equestria, Luna had to breach her agreement and see into her sister’s dream. It was harmless, she swore. She needed to know how she was dealing with her age, and how Celestia wanted to celebrate. The Solar Princess had long since done away with the idea of celebrating her birthday, deciding she was so old that it wasn’t even exactly certain when exactly she was born in the first place. Celestia maintained that it was pointless, and that her time and energy was too valuable to waste on such a personal endeavor.
Luna, however, disagreed. She thought that Celestia deserved to celebrate her long, beautiful life. She could understand Celestia’s reservations, but she thought the pros greatly outweighed the cons. Luna knew that there would be no convincing Celestia to accept a big party of any kind, so she decided she’d settle for a small, private ceremony. Just Celestia’s closest friends and confidants. No journalists or stuffy nobles. Just a hoofful of friends.
Which is why Luna felt obligated to breach her agreement and peer into her sister’s dreamscape. She didn’t know an awful lot about parties herself, and a thousand years of separation meant Luna wasn’t always privy to Celestia’s more recent shifts in taste and preferences. Luna planned to just take a quick glance into Celestia’s dreams, just to see what her sister liked. Of course, Luna was thousands of years old, but Celestia was still her big sister, and she sometimes forgot that Celestia was a grown mare with needs, desires, and less-than-pure dreams.
The things Luna saw in her sister’s mind were shocking. They were lewd, debauched, depraved, and generally unfitting of a princess of her stature. They had no place at anyone’s birthday party, nevermind the birthday of the Sun Goddess. Of course, that also meant that Luna found it perfect to celebrate her beloved big sister’s special day.
Luna decided that she’d need to do some alterations to her planning, but she was sure she’d give Celestia a party she’d never forget, for as long as she lived.
Celestia trotted across the quiet corridors of her castle, turning the note she had received from her sister over in her magical glow. It was strange, a letter like this from Luna. She had always been very succinct and to the point, both orally and in her writing, but this was different. She was being vague, evasive. All Celestia had to go on was that she was meant to meet Luna in her bedchambers after the Night Court had concluded. Although it was strange to receive a letter like this, Celestia decided to see what it was Luna wanted.
Celestia brought her hoof up to her sister’s door, knocking firmly on its surface. Almost before she could finish, the doors began to glow with a familiar cerulean light, opening from a quick pull of magic. Celestia was a bit taken aback, but she slowly stepped into the room nevertheless. The room was dark as she entered, which was to be expected given whose room she was entering.
“Luna?” said Celestia carefully. “Is everything—”
The doors slammed shut behind Celestia, leaving her blind in the shadows of Luna’s bedroom. She lit her horn, feeling around with her magic for the light switch. When she felt it in her aura, Celestia flipped the switch, flooding the room with light.
Sitting before Celestia was the Princess of the Night herself, holding in her hooves a small, wrapped gift box with a bright scarlet bow. To her side was a small table holding a simple, plainly-frosted birthday cake. Luna met her sister’s surprised glance with a satisfied smirk
“Surprise,” said Luna plainly. Celestia chuckled, shaking her head at her sister’s antics.
“Luna… You didn’t have to do this,” laughed Celestia. “I told you, birthday celebrations have lost their charm in my eyes. While I appreciate the gesture, it’s a shame you wasted so much time on me.”
“It has been quite some time since we spent some time together, and I reasoned this would make for a good excuse.” Luna smiled a bit more naturally. “Humor me.”
“Very well. I can’t very well think of something I’d rather be doing on my birthday than spending time with my sister, in any case.” Celestia matched Luna’s smile, her gaze falling on the box in Luna’s grasp. “So, what did you get me?”
“So very hasty. But fine. Open your gift while I cut the cake.”
Luna hovered the box over to Celestia, then turned to the table. Celestia chuckled to herself again, shaking the box gently. Despite what she said about birthday celebrations, she couldn’t deny that she enjoyed gifts. Not necessarily for the materialistic possessions (indeed, as the ruler of the kingdom of Equestria, there wasn’t ever something Celestia could ever need that she couldn’t easily acquire herself), but she appreciated the thought behind it. She shook the box gently to get a sense for what it could potentially contain and, when that yielded little information, used her magic to slowly and carefully undo the ribbons that wrapped around the box.
The box was mostly empty, save for a single scroll of tightly rolled parchment, bound by a crimson ribbon and a peculiar cerulean wax seal. Further inspection showed it to be Luna’s personal seal, which was curious, indeed. Luna very rarely made use of her seal, never having any particular reason to use anything other than the standard Canterlot coat of arms. Celestia used her magic to undo the ribbon, split the seal, and unroll the parchment to read what it contained.
“Decree of… Execution?” Celestia was very much so confused, her heart picking up in her chest. She turned her gaze to her sister, who grinned mischievously as she sliced into the cake. “Luna, what is the meaning of this?”
“Read it,” said Luna simply. Celestia felt a tingle run throughout her, but she turned her eyes back to the parchment to read the so-called decree.
“As ordered by Princess Luna, Princess of the Night and Lady of the Moon, as well the collective might of the City of Canterlot and the Kingdom of Equestria… The former Princess of the Sun and sovereign ruler of the Kingdom of Equestria shall…” Celestia gulped, fidgeting uncomfortably as she read. “S-shall be put to death, for the crimes of hedonism, gluttony, and… The selfish consumption of all of the castle’s pastries?” Celestia raised a questioning eyebrow. This had to be a joke. Luna was clearly showing her notoriously strange sense of humor.
“If you thought you could go about and get away with eating all the cakes and tarts without leaving a crumb for me, you were sadly mistaken.” Luna’s voice was absolutely, 100%, without a doubt, dead serious. “Your transgressions shan’t go unpunished, and the only penalty fitting of crimes such as yours is death.”
“Very funny, Luna.” Celestia let out a sigh of relief, shaking her head. She couldn’t believe she had let her little sister fool her like this. Of course, this was just Luna having a bit of fun. “I’ll admit, you had me at first. While an execution order might be a bit overkill, I respect the originality and creativity. Glad you haven’t lost your love of pranks in your absence, we had some fun—”
“I saw your dream last night, Celestia.” That one sentence was enough to freeze the Princess of the Sun in her tracks, to have her heart pounding in her throat. “I assure you, sister, this is not a prank. This is an official execution order, signed by me and the requisite three-quarters majority of the court. But one more signature is required to allow me to lawfully put you to death.”
“Luna… Those dreams, they don’t mean you can—”
“You’re dripping, dear sister,” noted Luna. Celestia glanced back, mortified to see that Luna was right; She was wetter than she’d ever been, her juices running down her hind legs and forming a small pool at her hooves. “Do not play me as a fool, Celestia. I know what you want, and I will give it to you. All that you need do is to give me the last required signature, to finalize the execution and leave me as the sole, sovereign ruler of Equestria.”
“Luna… I can’t. This is madness! I am a princess, for Goddess sake!” sputtered Celestia. “I have a kingdom to take care of, I don’t have time for such… such debauchery in my thoughts, nevermind in reality! Whatever you think you saw, I assure you, it was but the machinations of my overactive mind after a slice of cake before bed.”
“I can more than handle our quaint little nation, Celestia. You will be leaving her in very capable hooves. And, again, I implore you not to talk to me as if I am a fool. I know dreams, Celestia. Nopony has dreams that detailed, that vivid, so many times over unless it’s something they very dearly want.” Luna crossed the room, manufacturing a well-inked quill with her magic and offering it to Celestia. “Go on, sister. Sign it. Let me give you a birthday gift you’re unlikely to ever forget.”
Celestia fidgeted again as she accepted the quill from Luna, almost instinctively bringing it to the paper before she stopped herself. This was insane, truly ridiculous to even consider. She ignored how truly hot she felt at the idea of being dragged away in chains, being forced into a guillotine, dread building as she waited for that angry blade to fall into her neck.
“Promise you’ll take care of Equestria?” whispered Celestia, almost unable to believe that it was her that spoke. Luna gave a gentle nod, guiding Celestia’s quill back to the paper.
“I give you my word that I will take excellent care of my kingdom,” promised Luna. She leaned in close and whispered directly into Celestia’s ear. “And I promise to rape you senseless just before your life is snuffed out for good.”
Celestia’s breath caught in her chest, Luna’s words sending arcs throughout her entire body. It was no longer a decision fueled by rationale, or even a decision at all. Celestia didn’t think about it, didn’t decide to do it. It happened on it’s own, without her input whatsoever. She signed her name in the same neat, elegant, looping hoofwriting that she would use to sign a letter or a piece of legislature. But this wasn’t new tax law or education reform. This was far more sinister, far more exhilarating in every way.
Celestia had just signed her life away, and she couldn’t be any hornier about it.
“There’s a good girl. Perfect,” said Luna, rolling up the signed, notarized, official execution order and teleporting away to the court for review. “Now, Celestia, I’ve given this a lot of thought. Official protocol for execution is beheading by way of guillotine, but that seems unfitting of a criminal of your stature. So I’ve decided I’m going to give you a very special execution.”
Luna lit up her horn again, this time willing heavy iron chains into existence around Celestia’s legs. A leather band appeared around either of Celestia’s wings, binding them close to her body and painfully restricting her ability to fly. Finally, a steel band appeared around the base of Celestia’s horn, a single blue gem inset in the front of the magic suppression ring glowing faintly, seeming to constrict the ring tighter around Celestia’s horn with each passing second.
“Let’s get you to your cell.”
Celestia paced the length of her cell, as much as she could with the thick, heavy chain attaching her by the neck to the wall. She wasn’t sure just how long it had been since Luna had left her there, but she was certain she couldn’t be much longer. Hours should’ve been plenty of time to arrange an execution, and Celestia could only guess that Luna was teasing her, keeping her locked in her cell so that she could get the full experience.
Celestia had been locked in her tiny little cell for too long, her hooves still bound by her chains. When she was first led there, to her dark, damp, cold cell, she initially tried to create a bit of light, almost by reflex. The magic suppression ring around her horn put a stop to that quickly, jamming an arcane railroad spike of pain through Celestia’s brain.
That left Celestia all alone in the dark, her heart pounding in her chest. Part of her still believed that this was some elaborate prank on Luna's part, waiting for a release that would never come. A shiver ran down Celestia's back as she realized that there would be a release, eventually. A painful, bloody, permanent release.
If her hooves weren't currently chained together, Celestia would have reached between her hind legs to rub her hot, dripping, wanty cunt.
“Against the wall, prisoner!”
Celestia froze, her sister's voice cutting through the silence like a blade. She didn't move at first, too startled to act, but that all changed with a low hum of magic. Before she could take so much as a step towards the wall, crackling lightning ran through her body. The former princess screeched as she felt her every atom scream out in pain. Celestia collapsed, twitching as Luna strolled into view, tapping the bars with a large brass key.
“I said ‘against the wall’, did I not?” Luna came to a stop before the cell's door. Celestia panted, looking up at her sister. Luna had swapped out her typical crown for Celestia's own golden royal regalia, to really drive home reality: Equestria was Celestia's kingdom no longer.
“L-Luna…” gasped Celestia.
“That's Queen Luna, to you. It would do you well to respect your queen for the short period of time you have left.” Luna lit her horn with deep navy light, crackling with electricity. “Against the wall, prisoner, lest you receive another shock.”
Celestia could barely think after the initial jolt of magic, and so she didn't even think about arguing. She dragged herself away from the bars, pressing herself against the wall. Luna hummed in amusement, then used her key to unlock the cell and enter the room with Celestia.
“Canterlot has done away with final requests years ago. However, considering your former status as princess, the court and I decided to make an exception,” said Luna. “You may request one final meal, within reason and no alcohol or other illicit substance.”
“This is real, then?” croaked Celestia. “You really intend to kill your own sister?”
“If you do not have a request, I have no problem skipping right to the fun part.”
“Wait.” Luna raised an eyebrow, waiting for her sister to continue. “I never did have the chance to taste the cake you made for my birthday.”
“Cake. Of course. It's what got you here in the first place.” Luna used her horn to summon a plated slice of birthday cake, holding it in her cerulean aura a few feet from Celestia. Celestia could tell from where she sat that it was strawberry cake, her favorite. “Mother would often warn you to go easy in the sweets. She claimed it would cause you trouble down the line. I presume she meant the extra pounds it gave your flank.” With a wicked grin, Luna inverted the plate, dropping the cake to the filthy, dank, disgusting prison floor. “Who would have thought that it could cause you this sort of trouble? Eat up, prisoner. Enjoy it while you can.”
Celestia didn't respond, instead leaning forward and crawling towards her cake. Luna watched with amusement as the once-dignified Princess of Equestria attempted to lick the squished, squashed, soiled cake from the floor. In a way, Luna felt that it was appropriate. Chained and beaten, on the floor and at the mercy of her superior, this was Celestia's natural state. She didn't belong on the Equestrian throne. She belonged beneath Luna's hoof.
“Enough.” Luna gripped Celestia around the horn with her magic and yanked her head from her sloppy, messy meal. The former princess winced in pain, even the charge of outside magic causing her suppression ring to violently clamp down on her horn, shocking her mind with sheer agony. “You've made a fool of yourself enough as is. I presume you'd like to at least make it to the chopping block with a shred of dignity. Not like it makes much of a difference.” Luna grinned sinisterly, taking in her sister’s pain, her fear, her arousal. “Whatever dignity you have now, I plan to beat out of you before I introduce you to the void.”
Luna used her magic to unchain Celestia from the wall, turning the metal brace around her neck into a thick, tight leather leash with a simple arcane flourish. She tugged on Celestia’s leash, choking the former princess and dragging her forward. Celestia stumbled over her own hooves, barely able to keep up with Luna’s brisk pace as the new Queen of Equestria led her down the corridor. Celestia wasn’t sure where they were going, but she didn’t think asking would get her very far. Besides, she could barely think with the way her heart was pounding, the way her cunt was burning and drooling down her legs. Luna could sense her sister’s arousal, and she gave her leash another firm yank, laughing as the former princess just barely choked back a moan.
“Absolute degenerate. What manner of princess should be getting turned on by their sister choking them? Or greedily, hornily looking forward to your own demise?” Luna laughed derisively as she pulled Celestia around a bend, to a hallway with but a single door at the very end. “No princess at all. You should be ashamed of yourself. And, perhaps most disgusting of all, I know every word I’m saying to you sends another disgusting, despicable, shameful shiver of anticipation through your body. You want this so badly, don’t you?”
Celestia didn’t have anything to say, because she knew that Luna was absolutely correct. Her body trembled, partly in fear and partly in raw arousal, at the weight of what was coming next. She could hear her heart pound as much as she felt it, her legs twitching as her arousal ran down from her pussy. She had never been so turned on in her life, and the fun hadn’t even begun yet.
Luna pushed open the door at the end of the hallway, dragging Celestia into the room and slamming the door shut with her magic. Celestia flinched at the sound of the big, heavy door banging into place, and the padlocks and heavy iron deadbolts sliding into locked position. The room was a bit more spacious than the cell in which she had been waiting, but that seemed due to the additional fixtures; the walls were lined with whips, chains, paddles, and other, more dangerous tools that Celestia shuddered to imagine being used on her. There were no windows, no grates, no escape save for the door through which she had entered, which was very securely locked. There would be no one coming to save Celestia, if anyone even knew she was there.
“Luna? W-what’s that?” asked Celestia, pointing to the large structure before her, the entire thing almost to the ceiling and covered by a tarp. Luna hummed, levitating something from the wall.
Celestia was so focused on the tarp that she didn’t notice Luna, until she felt something connect with her flank, hard enough to cause her to squeal in pain. Celestia stumbled, dropping to her knees as Luna introduced a thick leather paddle to her ass over and over. The sound of leather against flesh echoed throughout the dungeon, each swat bringing Celestia closer and closer to tears. Luna spanked her sister’s ass raw, watching with delight as her juicy, alabaster flanks quickly shifted to an angry shade of red. She turned her attention to between Celestia’s legs, viciously slapping her cunt until the disgraced former princess was a moaning, crying mess on the floor.
“This shall be the last time I remind you, prisoner,” said Luna, satisfied with the agony her sister was displaying. She brought the paddle near her and gave it a lick, savoring Celestia’s juices. “I am your queen now, and you shall refer to me as such, or you will suffer for much, much longer than you need to.”
“I-I’m sorry,” choked Celestia. “F-forgive me, my Queen.”
“Much better. Since you are clearly curious, I’ll show you.” Luna used her magic to remove the tarp, revealing a tall, narrow wooden frame with what appeared to be a pillory at the bottom. There was a semicircle gap near the bottom, for the prisoner to place their neck. Above that, a piece of wood with a similar, inverted, semicircle, which was meant to slide down and lock in place over the prisoner’s neck. Before the loop was a simple wooden bench, and at the top of the frame was a wickedly sharp blade, held up by little more than a simple rope pulley mechanism.
“Oh dear Goddess…” gasped Celestia. Her heartbeat quickened, fear coursing through her veins. She had seen more than her fair share of executions over the centuries, but to be looking up at the blade knowing that it would soon end her life sent a shuddering chill throughout Celestia.
“The Goddess can’t help you know. Nothing can.” Luna fiercely spanked Celestia’s ass again. “You are at my mercy, Celestia. For all it matters, I am your Goddess.” Another spank, this time somehow harder than the one before. “Your body belongs to me.” Luna switched flanks, giving the left a swat to match that of the right. “Your life, mine to extinguish. Your very soul… Mine!” She punctuated that last word with a fierce, vicious swat beneath the tail. Celestia’s body heaved as she gasped air into her lungs, trying and failing to remain standing throughout the pain. She soon collapsed under her own weight, trembling in pain and humiliation. “How does that feel, prisoner?”
“P-please…” moaned Celestia. “Sister, please…”
“Please? Please what? Please stop? Please mercy?” Luna climbed over Celestia, straddling her from behind. Luna could feel the heat from Celestia’s pussy, the way her bruised, red ass quivered from anticipation and pain in equal measure. “Or please more? Please harder? Please end your suffering?”
“P-please… Please fuck me…”
Luna charged her horn with magic, molding her physiology with a rather simple spell. It was very easy for her to grow herself a long, thick, throbbing dark cock and heavy set of balls. She pushed down on Celestia’s head with her forehoof, using her magic to pull her hips up until she was able to rub her shaft against the former princess’ burning, wanty, desperate slit.
“And you think you deserve the honor of my cock in your useless cunt?” Luna’s voice wasn’t higher than a whisper, and Celestia felt it, in the heat of her breath against her neck, more than she heard it. “You’re a criminal, Celestia. You’re barely worthy of the blade that will end your sad, pathetic life, and you ask for my cock?” The Queen of Equestria laughed into her sister’s ear, teasing the tight lips of Celestia’s pussy with her cock. “Perhaps if you beg for it like a common whore, I’ll be amused enough to grant you this one last request.”
“P-please, my queen. I need it. Need you,” panted Celestia. She tried to wiggle herself back, to somehow impale herself with Luna’s rod, but the Queen held her firmly in place beneath her hoof. “Show mercy on me, let me feel you inside me…”
Luna laughed at her sister's desperation, amused by how little she resembled herself. Celestia was meant to be a strong, proud ruler, and yet here she was, begging to be fucked like a bitch in heat. The Queen pushed Celestia's tail to the side with her magic, giving herself a clear path to what was rightfully hers. She pushed her cock forward, spreading Celestia's cunt with her length. The prisoner gasped in pain, her captor’s massive member entering her too fast for her to take.
“Mmm, so wonderfully tight,” grunted Luna, feeling the blood from her sister's torn labia coat her cock. Celestia moaned as Luna wasted no time in rocking her hips, fucking her pussy with no regard for her well-being. Luna's cock was simply too big for Celestia's body, especially without giving the former princess a chance to acclimate. “But I fear you may be enjoying yourself a bit too much.”
Celestia let out a gasp as Luna suddenly exited her, her gaped, bleeding, ruined cunt feeling horribly empty. She breathed heavy, ragged breaths, wiggling her hips back, begging for Luna. The Queen had something else in mind, using her magic to grab one of her many tools from the wall. She laughed as she brought it forward, hovering it just in front of Celestia.
A long, thin iron rod with a simple hooked handle on one end. On the other was a plate of iron bearing the image of a crescent moon. Luna gripped the end of the iron with her magic, forcing energy throughout the metal until the image of her Cutie Mark was red hot. Celestia’s breath quickened, and, for the first time since her imprisonment, she resisted, fighting as if to escape.
“This seems much better,” said Luna. She brought her cock, slick with her sister’s blood, a bit higher, nestling between Celestia’s thick, juicy flank. She teased the much tighter passage as she hovered her branding iron to her own hoof. “Are you ready to scream for me, dear sister?”
She didn’t wait for a response, instead forcing every throbbing inch of her length into Celestia’s ass in one go. The Queen bucked her hips, her balls slapping against Celestia’s bountiful ass and an intoxicating wave of power washing over her. She owned every part of her sister, and she would use them to her heart’s content until she saw fit to throw her out, a moment that was inching nearer with each passing second.
“Be still, prisoner. I’d hate to have to redo this because you flinched and ruined the design.” Celestia froze, her heart stopping in her chest as she felt the heat from the branding iron approach her flank. Luna intentionally moved slowly, letting the dread, the anticipation, consume Celestia before she pressed the iron against Celestia’s ivory flesh. The prisoner let out an unrestricted scream as the room filled with the smell of her scorching, steaming, sizzling skin. Luna pushed the iron firmly into Celestia’s left flank, doing nothing to cease the movements of her hips while she pounded her ass.
Soon, she pulled the iron away, earning herself another choking, sobbing shout of pain as fresh air rushed against Celestia’s new burn. The prisoner felt as if she could barely stay conscious throughout the pain, but she still found it in her to glance back and see her knew branding; Luna’s Cutie Mark was scorched over her own, marking her as little more than the property of Equestria’s new Queen.
Queen Luna took the iron into her other hoof and, after giving it another quick heating, went about branding her sister’s other flank. She pressed the screaming hot metal to the prisoner’s ass, her already hard cock throbbing with excitement as Celestia screamed and cried. With the air heavy with the stench of burnt flesh and torched hair, Luna dropped the iron to the ground. Luna pulled her bloody cock from Celestia yet again, giving the prisoner a firm kick to the already abused, ruined cunt.
“Get up. Time to get you in position,” ordered Luna. Celestia trembled as she tried to stand, quickly collapsing from the pain. With a derisive laugh, the Queen grabbed a hoofful of her prisoner’s mane, dragging her nearly motionless body to the guillotine. She dumped Celestia onto the bench, opening the stocks and sliding the prisoner’s head into the slot. Celestia felt her heart pound, perhaps harder than before, as Luna lowered that piece of wood back into place, locking tightly around Celestia’s neck and keeping her in place.
“Let’s see… What’s next?” mused Luna, looking over her various tools. She grinned as her eyes fell on a heavy sledgehammer, so hefty that she required aid of her magic to wield it comfortably. She pulled it from the wall, dropping the head down to the floor and dragging it closer to the prisoner. The sound of the hammer head against the concrete sent a chill down Celestia’s spine, as she could do little more than theorize as to her sister’s intentions.
Luna’s intentions soon became clear as she raised the hammer, lining it up with Celestia’s horn. The Queen didn’t allow Celestia more than a second to process what was going to happen before she winded back and swung forward with all of her might, driving the hammer forcefully against Celestia’s horn. The sound of cracking bone was drowned out by a blood-curdling screech, followed by another crack, and another as Luna savagely smashed Celestia’s horn until the smashed, ruined magical conduit was jammed into her skull, more of the horn buried in her face than that which protruded outward. Blood dripped down Celestia’s face, her mind set aflame from the pain. Her vision doubled, her entire head throbbing with burning, electric agony.
The hammer fell to the ground with a clatter as Luna’s attention shifted to another tool from the wall. She settled on a wicked bonesaw, magically enhanced to easily slice through even the toughest of flesh and bone. Luna took Celestia’s left wing in her hoof, preening and straightening her feathers before bringing the blade of the saw to the joint of Celestia’s wing where it attached to her back.
Celestia thought she was out of tears, past screaming, but she was wrong. The drag of the saw blade against her sensitive wing, the teeth chewing and shredding at her skin. Her throat went raw from screaming, each stroke of Luna’s saw digging into her flesh bringing with it a pain the likes of which she had never experienced.
Thankfully, it wasn’t much longer until Luna hit the bone, sawing through it slowly, methodically. From there, she removed the blade, letting Celestia’s wing dangle down, attached to her body by a few threads of skin, sinew, and splintered bone. The Queen took the wing in her mouth and savagely yanked, twisting and pulling it until it popped free of Celestia’s body. Blood dripped from her new stump, pooling on the floor around her hooves. Luna took the wing and dropped it onto Celestia’s head, laughing at the horrified gasp she received from her prisoner. Luna made quick work of the second wing, although it was no less painful for Celestia to have her skin split and her arteries shredded. The right wing seemed to bleed a bit more than the left, and Luna left it connected to her body via a thin patch of skin. The wing hung down low, dragging against the floor with Celestia’s ragged breaths and developing a deep, crimson stain from the blood that had dripped onto it.
“I think it’s about time for your life to end, scum,” breathed Luna. Celestia could barely hear her sister with how awash her brain was with pain and pleasure in equal measure. This was exhilarating, her body torn apart bit by bit and ruined just before her life was claimed. It was the ultimate submission, the ultimate surrender of her body, and Celestia could think of nopony who deserved to claim her more than her sister.
A sharp slap echoed throughout the dungeon, followed by a pained wail, as Luna clasped her hooves to Celestia’s flanks, caressing the burns in her flesh. Celestia gritted her teeth, prepared to be violated further, but was pleasantly surprised when Luna decided on the less painful choice of her pussy. The Queen slid her throbbing, blood-slick length into Celestia’s cunt in one quick, harsh motion, wasting no time in sending her hips forward and slamming into Celestia’s pussy. The prisoner moaned as her sister abused her snatch, her entire body alight with pleasure from having her pussy stretched and used. Luna held Celestia’s body firmly in place, slamming her hips into her sister’s burned, scarred ass.
“H-harder,” croaked Celestia. “Yes, my Queen! Hurt me! Use me! Fuck me!”
A sick crack echoed through the room, and Celestia screamed, a new burst of pain exploding near her left foreleg. She tried to look back, but couldn’t see a thing thanks to the wooden frame holding her in the guillotine. All she knew was that something was wrong with her leg. Her shin had cracked, the bone splintering and jutting outwardly through her skin. Celestia could feel her leg twist and turn, her skin shredded by her own bone, until one good, hard, hefty tug yanked it from the rest of her. Luna hovered the limb she had literally ripped from her sister’s body before the prisoner, letting her get a good look at it before she took it into her own hooves.
“Just because I’m using your cunt doesn’t mean you get to enjoy yourself,” hissed Luna. Luna took Celestia’s leg, gushing blood, and slowly, painfully forced it into Celestia’s ripped, ruined, torn asshole. Celestia screamed, her pain mounting with each deep, unforgiving thrust of Luna’s cock into her pussy. Another crack brought with it another bloodchilling shriek as Celestia’s other foreleg was snapped and twisted with Luna’s magic. The Queen broke this leg a bit higher, above the knee this time, and yanked it free much like the first. She could feel her sister’s cunt convulsing around her length, the painslut very nearly cumming just from the sheer agony. Luna knew that she wasn’t far behind Celestia in that regard, and so she gripped the guillotine’s safety rope in her magic.
“Happy birthday, sister,” said Luna softly. Celestia’s ears perked, and it only took her a short second to realize what that meant for her. Luna could almost feel how hard Celestia’s heart was pounding, how much she desperately wanted this release, and she was more than happy to give it to her.
“T-thank you, my Queen,” gasped Celestia. She closed her eyes, tears running down her face and mingling with the blood from her shattered horn. “Please… Take good care of Equestria…”
The rope snapped and the blade sliced through the air, dropping like a stone. The steel sliced through Celestia’s neck and spine like butter with a sick, wet squish. Celestia’s body convulsed as her head rolled out of the guillotine and landing facing her own corpse, her dim, glassy eyes seeing nothing but dark.
Celestia’s legs twitched as her cunt clamped down on Luna’s cock, milking the Queen in her deathgasm. Luna let out a bestial groan as she came hard, depositing thick ropes of hot cum into her sister’s dead, ruined womb. She packed her creampie into Celestia’s rapidly cooling corpse, pulling her cock free to watch the blood and cum ooze from Celestia’s pussy.
Queen Luna grabbed her sister’s head and hovered it over to her cock. She spread Celestia’s lips and forced her length into the decapitated head of Equestria’s former ruler, cleaning her slimy cock with her dead sister’s tongue. Meanwhile, her magic was going to work to preserve Celestia’s body for future use, as well as to work out what changes she would be making to the country now that it was all hers.
“I will, sister dearest. I’ll take excellent care of my kingdom.”
