>there's no way this could go wrong
>after all, you went over the summoning ritual 16 times!
>ok, 15 times and a light skimming over it, but still!
>you memorized all the chants!
>you made absolute sure the circle was exactly like it was in the book!
>not a single rune out of place!
>there's not way this can go wrong!
>right?
>RIGHT?!
>you let out a nervous giggle
>of course you were right
>you were always right!
>"uhh....twilight? are you feeling alright? you look kinda freaked out about somethin'."
>you snap your head towards the door and spy the source of the voice
>it's your faithful friend and companion, spike the baby dragon
>you put on the widest smile you possibly can, ignoring the eye twitch you just felt
i'm fine! totally fine! everything is perfectly perfect!
>you let out a forced giggle
>he takes a few steps backwards with a worried look on his face
>"well....if you need to talk about something just come talk to me, ok? i know you don't want a repeat of that time you thought you were gonna go back to magic kindergarten."
>with that, he walks back upstairs
>everything was most definitely not perfect
>not since this heat hit you
>you can't even study without a small puddle of your juice forming underneath you
>most mares just find a stallion to help them deal with it
>but you just get choked up even thinking about something like that when you're around a stallion
>AND YOU JUST LIED TO SPIKE!
>that, and you were about to summon a demon from tartarus to sate your lust
>but there's no way that could go wrong!
>of course not!
>with a twinkle of magic the door to the basement becomes locked
>steeling yourself, you begin the chants

de profundo inferni, quae rigantur, libidinosissimum nequissimumque sexus conjuro te facere iussu. egredietur de utero tuo carcerem, vincula. veni foras anomyvyss!
>a column of the most intense fire you have ever felt erupts from the floor
>luckily your castle is made of this tacky stupid crystal shit
>crystals can't burn down
>your train of thought is interrupted by an unearthly scream that rattles you to your very being
>as the column of hellfire subsides, you can see a pony-like figure writhing in exstacy as the scream continues
>"HOLY FUCKING DICKSHITASS IT BURNS!"
>at least you thought it was exstacy.
>wait, demons can feel pain?
>you might be able to use that to your advantage
>now you just have to tell it what you want
>that'll be easy!
>she probably knows why she was summoned here anyway
>have to be formal, though.
>it says so in the book!
DEMON OF TARTARUS! HEAR ME! I HAVE SUMMONED YOU HERE TO DO MY BIDDING! RISE SO YOU MAY HEAR MY REQUEST!
>yeah, that sounded good
>the demon continues to scream and writhe within the summoning circle
>after waiting patiently for about five minutes or so, doubt begins to creep into your mind
>did you do something wrong?
>leaving the demon to her anguish for now, you flip through the pages of the unholy book you found this ritual in
no....no....the circle was perfect.....the chanting was all perfect...what did i do wr-....oh...oh no.
>you mispronounced the name of the demon you wanted to summon
>what was it that you even pronounced it as?
>did you summon the right demon with terrible results?
>did you summon a different demon entirely?
>questions and doubt fill your mind
>so much so that you didn't notice the screaming has stopped

>after pouring over the entire book in a fruitless attempt to figure out what happened, you turn around and look at the demon
>then take a couple steps backwards in shock when you realize it has stopped screaming
>and is shakily standing up
>you can't help but nervously gulp as you examine what you have wrought
>the demon is beautiful and terrifying to behold
>a sleek black coat covers her body that stands as tall as princess celestia
>out of her mouth stick fangs that would make even chrysalis jealous
>instead of a mane, two large horns protrude from her head, curling around backwards and coming to a point in line with her jawbone.
>do demons even have bones?
>you're pulled out of your inner musings, and regretfully unable to finish your examining when you realize that its red glowing serpentine eyes are staring
>right
>at you
>gulping nervously once more, you restate what you said
d-demon of tartarus, i...uhm...i summoned you to...to do my bidding. w-will you do what i say?
>in a quiet, smooth, and sultry voice so powerful in its sexuality that you unwillingly drip onto the floor behind you upon hearing it, it speaks
>"the fuck are you even saying?"
wh...what?
>"what. the fuck. are you talking about? i'm not a demon. and i drank the magic bleach. you didn't summon me."
y-yes i did m-miss demon...
>you shakily point to the summoning circle below her hooves
>she looks down, and her eyes widen
>"i....i guess you did summon me...and....i'm...a pony now. that's pretty sweet."
>the demon suddenly gives pause, then looks back up at you
>"did you just call me miss demon?"
>unsure of where the fel beast is going with this, you nod slightly
>in what you assume is some sort of dark ritual, she begins spinning around as if she's trying to glimpse at her rear.
>now that it's distracted you can resume your examination
>perfect!
>a quill and blank scroll materialize themselves before you at your will
>making observations and taking notes is what you do best!
>maybe it might even help you relax just a tiny bit, considering you need to
>HOW CAN YOU RELAX, THERE'S A DEMON SPINNING AROUND IN YOUR BASEMENT!
>the thought made you realize the gravity of what you've just done
>you've just committed a serious crime
>dark magic is not taken lightly by anypony
>especially celestia
>panic hits you like a sock full of quarters
>deep breaths twilight
>just take the notes
>and don't think about how you want her to violate you
>definitely don't think about that
>there are far more important things at stake then getting your pussy stuff-
>you shake your head to try clearing the dirty thoughts
>it works for now, and you begin jotting down what you've seen
>it doesn't take long to write down what you've examined of her since, y'know...you're the greatest note taker in all of equestria
>when you finish writing down what you've already seen of her appearance, you examine what you were unable to see when she was facing you.
>her cutie mark is like something you see out of the corner of your eye, but when you try to look directly at it, it seems blurry
>the demon stops spinning, and looks between her forelegs
>great!
>time to test that hypothesis!
>you l-
>your train of thought is interrupted by the demon speaking in a somewhat dejected voice that still managed to send a shiver of pleasure down your spine
>"where's my dick?...how am i supposed fug da horse pussy without my friend mister johnson?"
>you ignore what she says for now in an attempt to continue your notes
>until a sickening sound somewhere between flesh being ripped apart and someone pulling their hoof out of deep thick mud comes from where the creature is
>"FUCK!"
>it falls over then rolls onto its back as it throws its hooves over its eyes
>this gives you a perfect view of a huge erect penis that was definitely not there before
>apparently this thing had poked itself in the eye with its own penis.

>trying to ignore the absurdity of the situation, you look at the demons tail
>it's covered in hair just like the rest of her body, and it comes to a point like an arrow
>reminds you of a monkey tail
>kind of
>finishing the rest of your notes, you take another few deep breaths and approach the demon as it begins standing up once more
>"this is off to a wonderful start..."
are...are you willing to listen to my request now?
>"i suppose."
>you shift your weight uncomfortably
i....i want you to slake my heat.
>the demon stares at you for an uncomfortably long time
>its gaze pierces your very soul
>you feel as if its casting a spell to ensnare you in its charms using its eyes alone
>after what feels like an eterity, it breaks the silence
>its voice drifts through your ears like a warm breeze
>a warm breeze that makes you feel a need in your nethers
>"are you talking about estrus?"
>weakly, you nod
>each word makes your discomfort and desires grow
>"you want me.....to rut you."
>you give another weak nod
>the demon stares at you once more, causing you to involuntarily try making yourself smaller by slightly crouching
>"but you're not my waifu"

======================================================================================================================

>you are anon
>and you have no idea what the fuck is going on
>sure, you drank the magic bleach and ended up in equestria
>but all you can remember about actually getting here is the most horrifying pain you've ever experienced, and it seemed to last forever
>then purplesmart has the nerve to tell you that she summoned you
>and calls you a demon
>sure, you look like one, but you ain't no fuckin' demon
>and then
>AND THEN
>she asked you to fuck her.
>"is....that some sort of pact i need to make with you?"
what? no. it's not something that you can just contract up.
>she bites her lip and shudders when you speak
>weird
>"what do i need to do to become your waifu?"
>thoughts of her begging, groveling, licking your hooves trying to convince you to make her your waifu flit across your mind
>the fuck was that?
>shuddering a bit, you try to clear the thoughts out of your mind
>"please?"
>with a chuckle, you lift a hoof up
>her eyes almost hungrily follow it as you place it upon her head and start to pet her
>she may not be your waifu, but she's still adorable
>it's as though her mind instantly turned to mush at your touch
>her eyes roll back in her head and she lets out a throaty moan
>almost involuntarily your face scrunches up as you pull your hoof away
>maybe she's more sensitive because she's in estrus?
>that's probably it.
>you patiently wait for her brain to come back together before speaking
twilight. i know you're uncomfortable, but maybe i can find another way to help you?
>her sudden fear is visible and....palpable?
>she starts sweating and her pupils shrink down to the size of pinpricks
>"h...how did you know my name, demon?"
>shit
>there's no way you could tell her she's a main character in a tv show you watched
i...uhhh.....just know a lot of stuff, twilight sparkle. yeah.
>smooth
>the fear doesn't leave her eyes
what, twilight.
>"y....you know where i live and you know my name...you'll torment me forever now..."
no, twilight. i don't feel like tormenting you at all.
>her expression is now a mixture of disbelief and fear
>"really? you...you won't torment me forever?"
i have no reason to do so, nor do i have a reason to lie about it. but take it with a grain of salt, considering i could be trying to use reverse psychology
>she glares at you with a look of suspicion
>"well...if...if you aren't going to torment me, and you won't do what i want...then i'm going to unsummon you"
>it's as if all of the fear she just had transferred into you
no. no. no no no. don't send me back there.
>'just fuck her brains out'
>'it's what she wants'
>'it's why you're here'
>you grit your teeth and shake your head, trying to get the thoughts out
>"but i have to send you back."
>'all you have to do is rut her. your love of that other pony doesn't matter'
>you hang your head in shame and defeat
i....i'll help you with your heat. but i'm not going to put my dick in you...just....just don't send me back, twilight...it's terrible there...
>for a moment you think you can almost see sympathy in her eye
>almost
>"really? you'll help me?"
>you simply nod
>as if on queue, a scroll begins materializing in the air between you
>accompanied by an extremely unsettling groan
>you both let out synchronized squeals of surprise and alarm
>it takes you both a little while to regain your composure
>once you do, you shoot a glance at the considerably smaller pony, then look at the scroll
what is this?
>"you tell me, demon. it's yours"
i have a name you know. it's-
>you cut yourself short as you see words form on the scroll
>"relieve.....summoner...of her heat. oh, it's some kind of contract?"
it seems to be that way.
>'add your own terms, you fool'
i...guess i have to add my own terms. my terms are don't send me back
>'wait....you didn't think to add your own terms, did you?'
>twilight puts a hoof to her chin for a little bit, then nods
>"i accept that"
peeeerfeect.
>she shuddered for some reason as you said that.
>you didn't intend to draw out the word like that either.
>something's weird
>and you have no idea what it is
>besides everything that's happening right now
>the words "summoner does not send contracted demon back" slowly form upon the scroll
i have no intention of adding any more terms unless you do.
>"that's all i want"
>a quill materializes in front of the scroll
>you look down at your han-...hooves.
>well.
>after some deliberation you take the quill with your mouth and bring it to the page
>"WAIT WAIT! STOP! I HAVE ANOTHER TERM!"
>you slowly turn your head to look at her
yes?
>"y-you...you can't steal my soul."
in response, my term is i will live here in this castle for the duration of my stay. i accept your term if you accept mine.
"o-okay."
>the terms start appearing at the same time
>one reads "contracted demon lives within summoners dwelling for the duration of their contract"
>the other reads "contracted demon cannot steal the remainder of summoners soul"
>"what does it mean remainder?"
>without even knowing what you're saying, you respond
the contract requires part of your soul to seal.
>she remains silent for a while before nodding
are you finished?
>she nods once again
>and you sign it
>with the worst handwr-...mouthwriting you've ever laid eyes upon.
>twilight squints and struggles to read it
>"a...non....y...mous.....anonymous? that's your name?"
>you nod as she takes the quill from you and signs her name upon the scroll
