Celestia's Relaxing Vacation

Celestia walked with her head held high. Before she had thought that she would be ashamed once her secret was finally out, but the reality of it was quite different. She had murdered over a dozen innocents, children included, and was about to violate her own sister in public before getting off on her demise, and she couldn't have been more proud. The stares she received as she approached the plaza only served to increase her pride. It felt so exhilarating that for the first time she began to seriously consider making this a permanent vacation. Could she even go back to the life she had before? It would be so horridly boring.

Twilight followed behind her, shaking and staring at the floor as she walked. Unlike Celestia, the looks of ponies that they passed burned shame right down to her core, her whole body reddened and leaving a trail of her tears behind them as they walked. Celestia was a little disappointed in this, but considering how well Twilight had done where Luna was concerned, she would excuse Twilight’s clearly unwarranted shame.

Finally they reached the plaza. A crowd had already gathered, whispers and commotion moving through the crowd as rumors of why the Princess of the Night herself was restrained in the execution plaza, which despite its name had never actually been used for such in any of their lifetimes.

"Her Majesty, Princess Celestia!" announced one of the royal guard as she entered the plaza.

The crowd parted, and the majority of the ponies present made at least short bows in greeting to the sun goddess as she approached her sister. Her sister had been fitted snugly with her head latched into the guillotine. Her head was squeezed through the hole as it wasn't quite made for someone her size, and she strained to breath. She lay on her belly on a large smooth stone surface, her four legs hanging down over the sides, each of them securely tied to the ground. Her wings had been snugly bound to her back, so the only thing she could really move was her tail.

"Your Highness," a guard in a black hood that was apparently chosen executioner, "We were not sure exactly how you wanted her... situated. I hope we did not go too far by latching her in the guillotine." He didn't sound like he believed Celestia was really going to kill Luna, even with the duty he had been assigned.

"Ah yes the guillotine," Celestia spoke loudly, unafraid of if the common ponies heard her now, "That's a great deal quicker than what I had in mind for her, but it's as good a place to bind her as any." she turned to Twilight, "Twilight, raise that head up. My second should be proud of her deeds."

"I'm sorry, your Highness," Twilight raised her head, keeping her eyes on Celestia to avoid looking at the crowd, "Am I going to choose a new method?"

"Oh goodness no," said Celestia, "Luna is my sister, I should be the one to take her apart. I had something I was thinking about doing to you, but now I think perhaps I'll do it to her instead. I hope you don’t mind?”

“Not at all, your Majesty,” Twilight answered, trying hard to sound pleased at what they were doing.

Celestia smiled, “But first, we should obviously soften her up with a bit of pre-execution rape."

"Sister," muttered Luna weakly, barely able to keep her eyes open from the pain still stabbing through her head, "Look at what are you doing! Look at who you are doing this too! Please stop this madness, or you will never forgive yourself."

"Oh I am looking at it, and I assure you I am already drooling down my thighs from the sight," said Celestia, "Besides, what else can I do? You must die, so I may as well enjoy your execution, treasonous ex-princess. Don't you think?"

Celestia concentrated her magic onto herself and Twilight, forming the useful male bits between their hinds legs once again. The pain of such a spell had actually decreased, perhaps because she had used it on herself so often now. Even Twilight only swayed slightly as her body changed, looking down between her legs as if to confirm the thick sheath was now swinging there.

Celestia pranced about to Luna's securely bound plot, using her magic to loosen her leg bindings enough that she could squirm a little. She poked her nose downward and ran her tongue across Luna's dark slit. Not trying to pleasure her, Celestia just pressed her muzzle against her for a moment to get a good lap, wanting to taste her sister’s pussy while it was still fresh. She then slid her head up over Luna's behind. Sliding forward, she licked along Luna's spine as she pulled herself up onto her body. Her cock spilled from its sheath and was rock hard by the time it poked at Luna's waiting rape hole.

"Twilight, love," said Celestia, "Take her mouth."

"Um, yes I will," said Twilight, "Though... what do I do if she bites down?"

"Scream, I'd expect," said Celestia, "Rather loudly." She waved her head, indicating for Twilight to hurry. "If you accidentally set off the guillotine before it's time though, I'll be doing... things to you instead."

Twilight bowed her head obediently, and walked around to Luna's head. Despite her misgivings, watching Celestia already had Twilight's own cock raging hard as well. She nodded to Luna a bit apologetically, then pulled herself up to prop her hooves against the base of the device. Very careful not to touch anything that might set it off.

She flopped her cock against Luna's face, draping it over her muzzle, but Luna just shook her head, keeping her muzzle tightly closed. Twilight wasn't allowed to take no for an answer, so tried using her magic to pry open Luna's muzzle instead. It took a surprising amount of power, and Luna was still clenching with her muzzle open. If Twilight so much as slipped, Luna was going to clamp down hard. Twilight tensed up and pressed her tip between Luna's lips, sliding across her tongue to the back of her throat. Twilight’s face was a strange mixture of pleasure from the warm mouth and dread at the potential biting.

Celestia left Twilight to her own problems, pushing her tip to Luna's slit and feeling her sister's hot pussy clench tightly in resistance. Her eyes rolled back as she pushed deep on the first stroke, extending her cock so that she could open up Luna fully, sliding deeply into her bruised tunnel and past her cervix, which had already been torn asunder by Twilight's earlier attack. When she finally bottomed out against the back of Luna's womb, she began to thrust rapidly.

"Oh sister," Celestia breathed, "You have no idea how long I've wanted to do this." Though her previous fantasies had not typically involved killing Luna after doing it.

Likewise Twilight pushed her tip into the back of Luna's throat, then passed it, gagging her elder and watching as the thick shape of her cock swelled Luna's neck. She moaned at the warm feeling of a convulsing throat around her shaft, and began thrusting hard, her belly smacking Luna's nose and her balls bouncing against Luna's chin. Despite her eagerness, Twilight still blushed for the audience, trying to keep her eyes on Luna instead of them.

The crowd was full of ponies staring in disbelief as Celestia and Twilight double teamed Luna right in front of them. There was such a hush that one could actually hear the wet sounds of penetration as the throbbing cocks penetrated Luna from either end, not to mention the grunts and whimpers from Luna as she finally began to cry outright. A number of ponies left the premises, but a number more arrived and stayed as well, and a select few perverts had boners or juice drooling down their thighs.

Celestia moaned out shamelessly as the crowd watched, lengthening her strokes to make sure there was a good view of her cock sliding into Luna's tormented rape hole. With all the damage caused by Twilight, there wasn't even the slightest pleasure for Luna, her tunnel only convulsing in pain and trying to squeeze out the intruder, her hot behind wriggling against the impaling cock. Celestia looked around at all the eyes fixed on her actions, grinning proudly for them.

Celestia couldn't hold herself back for very long with the excitement of making her deeds public. She groaned and creamed hard into her sister's pussy, fully violating her in front of everyone and packing her seed inside. Luna's belly swelled and more seed splattered back, drooling down Celestia's balls and thighs, and still she rammed herself inside. After another minute riding out her orgasm, she finally tapered off and yanked her swollen fuck rod out of her sister with a long slurp.

Twilight wasn't long after, sending a torrent of spunk down Luna's throat and packing it in as Luna's throat rippled over the length of Twilight's cock. She rolled her eyes back as well, gripping Luna's head and thrusting as hard and fast as she could to pack her climax into Luna's swollen stomach. Her climax wasn't quite as happy as Celestia's though as Twilight lost her concentration for a moment and Luna bit down as hard as she could. Twilight squealed and pulled Luna's jaws back apart, grunting in pain as she pulled her bruised cock from Luna's muzzle. Clearly Luna now saw Twilight as more of a perpetrator than a victim, and Twilight was inclined to agree.

Celestia moved back from the setup and motioned to the executioner, 'You fuck her while I talk to my faithful student."

“I’m sorry, what was that your Majesty?” the guard didn’t think he heard that right.

“Fuck her,” repeated Celestia, “In whatever hole you wish. Enjoy it, not many stallions gets to put his dick inside an alicorn.” She paused, then added, “When you’re done, have the rest of her guard that’s on duty fuck her, any hole, preferably both ends at once, as well as anypony else that wants her, guard or citizen.”

"Well the other end has teeth so we-"

"So knock them out!" Celestia cut the executioner back off, sounding somewhat annoyed, "You're a professional murderer, surely extracting teeth isn't below you."

When Celestia turned back away, the executioner motioned to some of the other guards nearby. An earth pony guard and a bat guard approached her face, turned their bottoms around to face her, and after a great deal of reluctance, took turns kicking her head back and forth. One hoof slammed into her muzzle from one side, throwing her head to the other side where her muzzle was kicked back again as hard as they could. She let out a yelp with each kick, trying to scream for them to stop but not having much luck in the way of speaking.

By the time they did stop, a good number of her teeth were on the ground and the rest were quite loose. One unicorn guard then held Luna’s muzzle open with his magic as the another scraped out the remainder of her teeth, yanking one out at a time and then carefully checking to make sure he got them all.

On the other end, the executioner had pulled himself up onto her wide plot and jerked her tail out of the way. He pushed his cock into her wide open pussy to bathe it in fluid and cum, then pulled back, using that as lubricant as he pushed his tip to her tight asshole instead. He pushed hard, stretching her out slowly, purring as he penetrated her ball deep and began short rapid thrusts.

While the violated alicorn was getting her teeth extracted and asshole fucked, Celestia turned her attention to Twilight.

"So Twilight," Celestia said, "What do you think of all this?"

"Think?" asked Twilight, glancing over to Luna, "Oh well... I feel sorry for Luna, but it's also really hot to watch her suffer like that."

"It is isn't it?" Celestia smiled, "You are technically the second most powerful pony in Equestria, politically at least. That means that, within reason, you are free to rape, torment, or kill our subjects. But remember: moderation. We don’t want to run out of subjects, or push them to the point that they’d rather die fighting us than to continue under us. Additionally, we do not do this to loyal guards or government employees without my okay. You can, however, ask your guards to bring you someone, like if there’s someone you knew in Ponyville or Canterlot that you’d like to murder.”

“Yes, your Majesty,” Twilight head was a buzz. She didn’t want to just kill random ponies, and definitely not ponies she knew if she didn’t have to, but would Celestia expect her to do so occasionally? Subconsciously, she began to sort everypony she knew in the back of her mind from least to most muder-able.

“But I want one thing to be clear." added Celestia, “You are still my personal property to use, torment, or kill at my whim. Since you supported me against Luna, I'll let you have a room inside the castle, but you're still going to sleep on the corpse pile and eat out of your pet bowl, and we'll still have our play time every night that I can."

Twilight nodded, ducking her head slightly lower with each sentence from Celestia, "I'm sorry, I didn't mean to-"

"And don't even think about leaving the palace or doing anything that I haven’t specifically given you permission to do," Celestia said, "You don't even use your magic without my permission, not for so much as lifting a spoon unless I tell you that you can, or in situations where you are defending the throne from traitors like Luna."

Twilight nodded again, "I won't try to run or do anything out of line, I swear it." Twilight wasn't stupid, and she knew Celestia almost certainly had some kind of magical tracking device placed in her by now. There was really no escape, and if she did it would only endanger everyone where she escaped to. It was a relief though to know she didn't need her horn brace anymore.

"That's it, my faithful fuck toy," Celestia leaned over and licked Luna's juice off Twilight's horn, making her shiver.

As the two spoke, one of the particularly perverse civilian mounted Luna’s head, the first stallion of the night to slide his slick cock into her muzzle, lubricated by her blood as it drooled down his swinging balls. He thrust hard, moaning as if it were a dream come true to have the royal throat gagging around his rape stick. The executioner too finally came solidly into her tail hole, pushing streams of his cum deep into her bowels. He smacked her flank playfully and dismounted, only to be replaced by another night guard who plunged himself into her gaping pussy.

Celestia turned back and leaned down to look at Luna's eyes as cock was plunged down her throat. The night goddess was sobbing by this point, completely out of control and knowing that she faced a long torment. Celestia leaned over and licked the tears off one side of her face, then smiled gently at her.

"I want you to be completely violated like the worthless cum bucket that you are," Celestia told her, loudly so others could hear, "So I'm going to leave you here tonight, dear sister. Anyone and everyone that wants a go at you will have it. Word will spread fast and the worst scumbags of the city will be lining up to ram their cocks into you." She licked slowly up her face again, "And then when you are completely humiliated like you so grossly deserve, I will come for you, and your long, fruitless life will come to a gruesome end."

Celestia turned back to Twilight, "Can you do gender changing magic Twilight?"

"Um, yes," Twilight said quietly, "I think at least, I mean I studied all sorts of spells, I haven't really used it very much aside from experimenting on Spike.”

"Good enough," said Celestia, "You will remain here tonight and provide services to any mare that wants to have a go at Luna. You may send for a royal mage if you are too weak and pathetic to perform this task on your own."

"I-" Twilight started to bring up needing sleep, but then thought better of it. "You can count on me."

Celestia was perceptive, "Just take power naps between castings, you'll be fine. Most of those interested will be stallions." She stroked Twilight's face, "One more thing. Luna is to still be in one piece when I come for her tomorrow. If she has been killed or seriously maimed early, by you or anypony else, you'll be taking her place in the gallows. Understand?"

Twilight bowed low, shivering, "I understand, your Highness."

"Good," said Celestia, "I’'m going to get some rest. I'll see you after I raise the sun tomorrow."
