Day this isn't even Riskquestria in Equestria
 
>You are princess Celestia
>?your mind raced as you flew towards the crystal empire
>?what was this talk about some evil king rising up and enslaving its people?
>?you would put things straight, luna could safeguard canterlot while you were away
>?as you flew overhead, you could see them
>?the horrid factories
>?the war machines
>?all being manned and pushed by crystal pones in shackles
>?it was awful, you would do your best to put everything right again
>?you descended to the castle in the center of the city
>?landing on a balcony, you stepped inside hesitantly, curious as to whether or not he knew you were approaching
>?as you explored his domain, you could hear laughter from a nearby hallway
>?following the noise, you continued deeper into the building
 
>?you felt as if you had been following the noise for a while now
>?at least ten minutes you had continued, was the castle really that large?
>?on the walls were decor of what you assumed to be the new king
>?portraits of him and his empire
>?some of him with his loyalist soldiers
>?some of them whipping his slaves
>?they disgusted you, you would make sure this was put to an end
>?after following the noise for a good 20 minutes, you finally came across a large set of doors
>?storming inside, you saw him on his throne, alone
>?He stared at you with a knowing look, as if daring you to continue
SOMBRA, THIS HAS GONE ON LONG ENOUGH
>?He merely laughed in response
>?before you could retort, his horn flashed red and several portals opened up around the throneroom
>?Sombra's loyalists poured out en masse, quickly surrounding you
 
>?It was futile, you were an alicorn and these crystal ponies stood no chance before your might
>?his soldiers defeated, Sombra looked at you with a grimace
>?you frowned, as you advanced upon the evil king
>?with a yellow flash, he was down and you were standing above him
You have given me no choice, I will end this...
>?You raise your horn, as if preparing to gore Sombra
>?his horn flashes red again, and you feel yourself losing concentration
>?You look down into his eyes
>?you start to feel dizzy
>?unable to focus on your magic anymore, you take a few steps backwards
>?He rises as you move, continuing his spell
>?your limbs start to go numb
>?you fall to the ground, unable to continue to support your own weight
>?sombra continues to advance on you, his horn still glowing an unholy red
>?starting into his eyes again, you feel yourself growing weaker... until you can no longer feel your body at all
 
>?stepping back, Sombra admires his handywork, a sadistic smile on his face
>?you try to move your body, flap your wings, feel your magic, but you can do nothing
>?the situation feels totally helpless until you suddenly feel your body jerk forward
>?the glow on sombra's horn has long since subsided... who is controlling your body?
>?you stand again, but try as you might you cannot tell your body what to do
>?its as if you are a spectator trapped inside your own mind
>?you start to walk forward towards Sombra again
>?as you do, he moves backwards, working his way back to his throne.
>?he seats himself once more, and you follow, unable to stop yourself
>?you sit at the foot of his throne and look at him unable to even move your glance.
>?with a sadistic smile he looks down, and your head follows the motion
>?underneath his body, you could see his growing erection
>?you are taken back mentally, but your body has another idea
>?leaning forward your head stops right in front of his growing member
>?you try with all your might to pull backwards, mentally thrashing out against your own body
>?nothing works
>?you cry out mentally, unable to stop what happens next
 
>?You take sombra's member into your mouth, slowly sucking on it
>?oh god you can still taste it
>?sombra lets out a laugh as you continue
>?your head moves slowly, sensually taking more and more until he is pushing at your throat
>?sombra places his hoof on the back of you head, as if encouraging your enslaved body to continue
>?you take as much of him as you can, your body suppressing its own gag reflex
>?unable to breathe, you remain in place
>?you try to scream out, your body begging you for air
>?but nothing happens
>?finally you pull back, filling your lungs with sweet oxygen
>?but its not over, you start bobbing slowly, your tongue sliding along the bottom of his stallionhood
>?your body picks up the pace, deepthroating him with every push
>?sombra lets out a series of low grunts
>?oh god no
>?this can't be happening
>?you start to pull off his member again, stopping at the tip
>?you give one hard suck, and he releases into your waiting mouth
>?opening wide, you leave your tongue on the tip, attempting to get as much as you can
>?he shoots load after load into your mouth
>?you catch most of it, some of it getting on your face and in your mane
>?finally spent, you swallow, licking him clean to finish the job
 
>?you pray its over... that you can find a way to take control again
>?your prayers go unanswered
>?you step back and look up, a satisfied grin on Sombra's face
>?his horn glows red again and you can feel your body responding again
>?before you can move, its gone again, but not completely
>?he left one part of you under your own control....
>?turning around, you move your tail, inviting him in
>?he steps off his throne and walks towards you, already prepared for a second round
>?you could feel your marehood... it had already gotten wet without your approval
>?he puts his forehooves onto your back, pushing your wings to the ground
>?rather than let your body position itself, he chooses to do it the old fashioned way
>?forcing the front half of your body to the ground, there was nothing you could do to stop him
 
>?with another low laugh, Sombra pushes into you
>?you resist as much as you can, but it is hopeless
>?he forces his way past your only means of defense with ease
>?your bodies meet at the hip
>?starting out slowly, he pushes in and out with vigour
>?before long, his slow strides have picked up speed
>?you can feel all of it, the control he has given you sending you over the edge
>?sombra laughs again, as if mocking you
>?You can't stop it at this point, embarrassed at yourself from taking pleasure from the act
>?Sombra showed no sign of slowing down, the increased lubrication just making his end easier
>?pushing harder and faster, his body slammed into yours
>?his pace quickening, you could feel him twitching inside of you
>your body involuntarily clinches down on him
>?he unloads into you, your body willingly taking it all
>mentally screaming, you could feel him filling you up
>humiliated that your body responds so natually to having him unload inside of you, you wish you could cry
>?He finally pulls out, coating your flank with the last of his cum.
 
>?your body turns around shakily and cleans your juices off of him
>?he walks back to his throne and retakes his seat
>?you make your way to a room nearby and open the door
>?inside you see all manners of crystal pony, the same look of defeat on their faces
>?all of them mares.... all of them slaves... like you
>?a tear falls from your eyes, you are unable to take pride in the fact that you did it yourself
>?your body moves slowly to a corner of the room and sits waiting
>?waiting for it to be called for again
