Celestia's Relaxing Vacation

To Princess Cadence and Shining Armor, the first indication of something amiss was a sudden flow of refugees from Canterlot and Ponyville. The rumors that followed with them didn't seem possible, but certainly needed to be investigated. Still, their royal guard encouraged the couple to stay in the Crystal Empire until a messenger came back with a response from Princess Celestia.

Sending messengers hadn't done much good though. The first one they sent was held for several weeks as he waited for Celestia to get time to see him, then sent back empty hooved. They gave it another week before sending another, which was outright refused an audience with Celestia and sent back immediately. Their only message was that Celestia would speak to Cadence and Shining only to explain recent events.

It was against their better judgement to go, and were encouraged not to, but eventually they felt they had no other choice. They needed to find what was going on, what Luna and the Elements' fate had been, and Shining was especially worried about his sister. It couldn't be as bad as the rumors after all, could it?

They were allowed entry into the palace and were on their way to the throne room when they ran across someone else however, Twilight, who was on her way out of the throne room herself.

"Twilly!" Shining exclaimed, rushing over to Twilight and laying a big hug on her.

"Twilight," Cadence walked up behind him, "It's good to see that you're... um... okay. Are you okay?"

Twilight's swollen belly was starting to show at that point. The same magic that was keeping her fetus unharmed during happy-fun-times was also accelerating its growth. Not to mention the fact that she was wearing thigh high black socks and the collar emblazoned with 'Celestia's Pregnant Slut'. Twilight initially stammered instead of speaking, not having expected to see them here.

"Twilight," Shining asked seriously as he pulled back, "What has gone on here? Do you need us to take you away from here?"

"Twilight we will help you in any way we can," said Cadence, "Is it... safe for us to speak with Celestia?"

The easy answer was no; they would risk their lives if Celestia so much as saw them here, as she had no doubt been waiting for just that to occur. Twilight's mind buzzed. She could tell them to turn around for their own good, and there was a chance they might do so. But something kept her from giving that answer, and that something was that her pussy was drooling down her hind legs just as the thought of what Celestia might do to the couple. Even the thought of her brother... ESPECIALLY the thought of her brother, getting the royal treatment made her so hot that she began to shiver.

"Are you okay?" asked Shining when she didn't respond, "You're shaking..."

"I'm fine," Twilight unsuccessfully tried to sound casual, "Celestia is fine too, just really busy lately. She had to deal with some things, but only did what she had to do." What she had to do to get off.

"What's with the collar?" asked Cadence, "Did she... rape you?"

"I've actually been enjoying my new roll," Twilight brushed over the question, "She even let me knock her up too!" She realized too late that that was not how Past Twilight would have put it, and she should probably be trying to act at least a bit like her old self.

It seemed to have caught them off guard as well, "You did what?" asked Cadence.

"We're sort of a couple now, you know how close we are," Twilight tried to gloss over it, "Anyway, I really think you'll understand once you talk to her. Let's go see her together!"

"Very well," Cadence said, "I trust you."

The three walked together towards the throne room, Twilight walking in the rear admiring her brother's behind. Twilight opened the door for them, then bowed low for Celestia. Cadence and Shining gave a token bow as well, though they definitely had their serious faces on. Once through the guards shut the door once again, locking them with a click, the couple might be starting to realize what was happening just a little.

"Ah there you are, greetings," said Celestia, sitting back on her throne, "I've been expecting one or both of you to visit me."

"Princess Celestia," started Cadence, "Greetings, but I fear we come with serious concerns and-- Oh my gods what is that!" Cadence's eyes went to the other throne, where Luna's severed head still sat.

Celestia feigned ignorance for a moment, looking around, then finally nodded, "Oh that. That is my dear sister Luna's head. Don't you recognize her?"

"A-and where is the rest of her?" Cadence was wide-eyed with confusion, while Shining jaw-dropped silently beside her.

"Well," said Celestia, "Her torso is in my room, and her limbs are laying around somewhere in Twilight's room I think. Hello Twilight, by the way. I see you didn't go to your room as I instructed."

"Greetings your Highness," Twilight nodded, her shivering worsening, "Please forgive me. I thought that you might want my presence for... things."

"Celestia!" Cadence cut in, "W-why did you kill Luna? Did you kill the other Elements as well as the rumors say?"

"Oh yes, all of them," said Celestia kindly, "Twilight is only alive because she's been properly deranged, but I'll be killing her as well. Eventually."

"W-what?" said Shining, "You keep your hooves off of her!"

Twilight bit her lip and pushed her hind legs together in excitement as things went south, eyes still focused on her brother's behind, impatiently anticipating what she might be allowed to do with him.

"Why?" repeated Cadence, "Why would you do such a thing!?"

"Honestly?" answered Celestia, "Mostly to get my rocks off. I've learned to give in to some of my fantasies, and discovered how very much fun they are. Luna disagreed with this sort of activity, so she was forced to join in the fun. Would you like me to detail how I killed them?"

"What? No!" Cadence said in horror, "I... "

"You have to be stopped!" said Shining, not really considering the repercussions of what he said as of yet.

Cadence wanted to avoid immediate confrontation, but all the same... "Celestia, we intend to take Twilight back to us to the Crystal Empire. You've clearly already had plenty of fun with her. Please allow us to do this."

"Oh goodness no," said Celestia, "I don't think she wants to go anyway. If I was to guess, I'd say she wants to see me forcing some fun time on you."

"I don't want to fight you Celestia," Cadence said. Though she clearly meant to go research a way to do so.

"I don't think I have much to worry about from you, dear" Celestia smiled politely.

"You aren't just facing her!" Shining said, "And not just me either! Twilight isn't going to take your side in a fight! Are you completely sure you can take all three?"

Celestia laughed, then tilted her head to look past them at Twilight, "Twilight, whose side would you take in a fight?"

"Yours, your Highness," answered Twilight, her voice shaking, "As I did with Luna."

"Indeed," said Celestia, "Luna could have beaten me soundly had Twilight taken her side. Do you think Twilight led you here with the intention of getting things resolved? She even risked disobeying me because she didn't want to miss seeing it."

"Twilly you don't have to be afraid of her!" Shining called back to her.

"I'm sorry brother, but she's right," said Twilight, "I led you in here knowing this would happen. I'm not shaking from fear, I'm shaking because I'm literally drooling a puddle on the floor from arousal." She looked almost dizzy, "I'm really hoping she lets me have a go at you. You know I've always had fantasies with you..."

"What did you do to her!?" Shining demanded to Celestia.

Shining's horn lit up first, followed quickly by his wife's. They were quickly surrounded however. Celestia, Twilight, as well as four guards that were in the room, took positions around them, ready to strike.

"You can't do this!" said Cadence, "You can't just assassinate the leaders of a nation! There would be war if you did, thousands could die!"

"Well as fun as slaughtering your subjects would be, that probably wouldn't be in their best interests," said Celestia, "It would be a shame for the crystal ponies to be victims of genocide so soon after earning their freedom."

"You wouldn't!" said Cadence.

"I wouldn't?" laughed Celestia, "You can't possibly believe that at this point."

"She would," said Twilight, "And at this point, I would too."

"Lower your horns and submit," said Celestia, "If you do, I will annex the Crystal Empire in the most peaceful way possible. If not, then I am fully capable of burning your city to the ground without expending a single soldier on my side. Furthermore," she turned to Shining, "Resist, and you may watch your sister die in the most agonizing way I can come up with."

"Do I still get to fuck Shining first?" asked Twilight quietly.

"Yes dear," answered Celestia gently, "Not to worry."

"It would be easier for you if we told our people to submit," said Cadence, now seeming to backtrack from valiantly defending Twilight to bargaining for her own life, "We can't do that if we're dead."

"You'd be surprised what I can make you do when you're dead," cooed Celestia, "You do realize that I don't have to even offer this. The two of you won't more than bruise me before you're both down. You're lucky that your submission is amusing enough to me that I would even offer it."

Cadence took a deep breath, and looked at Shining. They seemed to share a brief moment of understanding and then suddenly both turned to move to Twilight. Shining raised the strongest shield he could around the two, glowing bright blue around them, and Cadence tried desperately to get a teleportation spell around the three of them. In a large flash of light, the trio disappeared into thin air.

"Well that was predictable," sighed Celestia.

"Should we go after them, your Highness?" asked the nearest guard.

"No, just give it a few moments," said Celestia.

Sure enough, a few seconds later there was a bright purple flash in the center of the throne room. The trio reappeared, Twilight having teleported them back here as soon as they had arrived.

Twilight heaved a sigh of relief, then immediately lunged towards her brother, headbutting him hard and bringing their horns together. Without hesitation or restraint, she sent a wave of energy into her brother's horn, catching him completely off guard, making his shield blink away in an instant. Twilight was a great deal more powerful than he was, and it was seconds before his legs gave out beneath him and he tumbled to the floor, Twilight following him to the floor and continuing her assault.

Celestia was out of her throne in an instant and in Cadence's face, bringing her horn to Cadence's and doing the same as Twilight, sending torrents of energy through her horn. Celestia was not only more powerful than Cadence, but she was a great deal more powerful than she used to be due to her new habit of devouring souls. She shattered Cadence's horn without even meaning to, causing the pink princess to scream and crumple to the floor, curling up and holding her head in her forelegs.

Celestia zapped Cadence for a few more moments, mockingly reaching a hind hoof to rub at her nethers as she did so. As Cadence passed out, she turned to look at Twilight, who was still buzzing away at Shining, straining and clearly attempting to mimic her mentor's horn breaking trick. His horn cracked slowly, then a few seconds later shattered into fragments just as Cadence's. Twilight moaned, rubbing her soaked pussy with one forehoof as she continued to zap him. One he had passed out, Celestia gently put a hoof to Twilight's cheek and pushed her head away, lest she kill him early in her excitement.

"Good job, my love," said Celestia, "We make a great team, don't we?"
