The Art of Reprisal

"Starlight is your Empress, I am her slave. You will obey Starlight." Chrysalis instructed Twilight, who stood in a trance. Starlight was glad that it still existed within the changeling version of Twilight - the fact that it might've bled off when she transformed having posed a conundrum to the unicorn who was already running out of steam for mind control spells.

They had since moved into the castle itself, Trixie and Twilight having apparently had a lengthy discussion about a smattering of subjects that Twilight summarized as 'certainly interesting and definitely eclectic'. Now they stood in Twilight's room, with Trixie waiting by the door that had it's silence charm shimmering happily across its surface.

"Starlight is my Empress and I obey her." Twilight repeated, her expression blank as the words sank into her very soul.

"I think that's enough, Twilight, awaken now." Starlight said, stepping in front of Chrysalis - who bowed to the mare with an intense blush. Twilight shook her head, and then saw Starlight before her. She blushed and bowed her head to her new Empress, the emotions that had been fostered by the changeling obviously having transferred with the title of Empress.

"I am glad to see you, Empress. I am at your disposal." Twilight said. Starlight had to check her escalating emotions at that proclamation - the temptation to take Twilight right then and there being quite the strong one.

"I have asked my other slave, but I wanted to see what you had to say." Starlight began, briefly nodding back towards Chrysalis. "Do you think that there might be a possibility of reversing what Chrysalis has done to you - namely your transformation." Twilight paused, thinking the question over.

"As far as I understand it, and my understanding is by no means complete on this matter," Twilight began, couching her words heavily, "I doubt that the process of metamorphosing into a changeling can be undone. It's a deep magic that likely has more power to it than most any spell that ponies or any other creature have devised."

"Rats..." Starlight cursed with a huff. "I suppose that means you are a permanent changeling then?"

"That would be the long and short of it - though as a changeling I am more than able to make my appearance that which pleases you." Twilight offered, missing the point of Starlight's words.

"Well, at least you aren't under Chrysalis' control anymore." Starlight shrugged. "By the way, Chry-"

"Yes, Empress?" Chrysalis asked, poking her head out from the bed where she had pinned Trixie without a noise. Trixie's eyes were rolled up and away, revealing more white than Starlight had though possible, and her mouth was filled with pillow while her pussy was filled with ovipositor.

"Oh... you're already on it... her. Good job."

"Thank you, Empress!" The changeling said with a broad smile before returning to fucking Trixie ragged. Starlight made a mental note to ask for much the same treatment later. The ass fucking was all well and good, but getting pinned to the bed and getting her pussy fucked ragged... that was just something else entirely!

"Anything you'd like me to do for you, Empress?" Twilight asked. Starlight considered this for a moment and then nodded with a smile.

"Yeah, I can think of something for you do to." She hooked a hoof behind Twilight's head and pulled her forward while falling backwards herself. Landing with a thump, She smiled up at the bewildered Twilight. "Eat me out, Sparkle." Twilight lit up with an adoring expression, and instantly jumped to her task - literally.

Starlight sighed in contentment, pleased with how everything had turned out. The world was, as much as it could be, right once more. Twilight was no longer under the control of a megalomaniacal, egocentric, maniac of a tyrant, and Starlight was instead in power.

Starlight could make sure no more mishaps of this sort ever happened again, and would have the benefit of the use of not only what had been Equestria's greatest foe but also the ruler - and one of the former rulers - of Equestria. Life was going to be good so long as nothing came along to spoil it.

That did, though, bring up an interesting question for Starlight's consideration.

With the propensity of the enemies of the state to go after either the current or former - or both - rulers of Equestria, should Starlight take Celestia as well? Twilight and Luna had already been taken and had irreversible damage inflicted on them - damage that would manifest fully as psychological trauma if the spell the changeling had them under was broken - so Starlight felt at least morally justified in taking over management of the two ponies.

Would taking Celestia be the right thing to do? It would make things easier - and plus it would give her the chance of a lifetime to fuck the princess of the sun. It was pretty tempting.

Let Celestia go and definitely have the moral high road, but miss out on that princess ass; or take Celestia with her spell and save Equestria the possible grief the future might bring will getting to indulge in all the delicious fetishes the rest of Equestria could only dream of.

It certainly was something to think about in the very least; and what better way to ponder such deep moral quandaries than to have Twilight between your legs while you were thinking? This was certainly good, and no matter what, Starlight could only see it getting better.
