Celestia's Relaxing Vacation

The two Celestias and Twilight stood at the portal, naked and relatively sated with their fill of raping and murder for the day.

"Well, I suppose you won't take me with you," sighed human Celestia.

"Oh goodness no," chuckled magic Celestia, "That would be too confusing."

"We're gonna kill you!" pipped in Twilight happily.

"Oh well," shrugged human Celestia, ,"I guess that's almost as good, just make it painful okay?"

"Actually, I had a better idea," magic Celestia cleared her throat, then turned to the other her, "I'm going to give you magic. Not nearly as much magic as I have, and you can't eat souls and such things to grow more powerful, but it won't take much for you to be able to subdue a non-magical world. You can find this world's Twilight, and train her in the same way I've trained this Twilight, or kill her, I don't care." she sighed herself, "I just can't bear the thought of leaving this world without a proper monster to drive fear into the hearts of its citizens."

"R-really?" human Celestia's face spread into a huge grin.

"Sure," smirked magic Celestia, "So collect the bodies to start your corpse pile and get started, just remember, I reserve the right to return at any time and kill you and/or everyone else."

"Absolutely!" human Celestia was nothing but agreement.

"Aw," Twilight whimpered from next to the portal.

"Oh don't be like that," magic Celestia looked back at Twilight, "I tell you what. How about when we get back, I torture you for a week as punishment for speaking for me just now." Spoken in the same tone that a parent might offer their child ice cream for being good.

"Really?" now Twilight was smiling as well, and waited patiently for time to go and be tortured.

"Can I still not fuck children?" asked human Celestia.

"No, nor can you fuck anyone else if a human child can see you, but you can brutally murder them all day long," reminded magic Celestia, "Don't worry, you'll know all the rules once you're magical and more of a main character."

And with that, human Celestia felt new energy surging through her body, growing more and more.

"What about if she dragged them through the portal and raped them on that side?" Twilight suggested. "You could drag them back here to kill them, or kill them on that side so that they'll stay a pony and you can still fuck their corpse."

"Hm, not a bad idea," admitted magic Celestia, "A good idea in fact, that's why your my number one fuck slave."

"You misspelled you're," said human Celestia, then blinked, looking very unsure for a moment.

"See? You're getting the hang of it already," magic Celestia patted her on the back.

Regardless, human Celestia was plenty happy with how things turned out. She turned and ran nakedly towards the school, excited to start her reign as the planet's new fuck-goddess.

"Not so much as a thank you? Oh well," Celestia shrugged. She reached out to Twilight, shoving her towards the portal, intending on following shortly after.

Twilight hit the wall with a dull thud and fell back onto her ass, swaying back and forth. Celestia quirked one eyebrow, and reached a hand to casually feel of the wall herself. She then picked up Twilight by the neck, and slammed her head into the wall several more times as if to make sure.

"Huh," she said, dropping Twilight's now-unconscious body to the ground, and sounding like she wasn't entirely sure what to feel, "The portal seems to be missing. I think maybe somepony got clever while I was gone." She slowly smiled, "But sadly for them, not clever enough."
