>The candles are lit.
>You quadruple check that the hidden door that leads to the rest of your castle is still locked.
>No way are you taking chances with this.
>You’re desperate, but not foolish.
”Alright Sparkle, keep a focused mind. This is going to be the only way you’ll manage to pull it off.”
>Hopefully after it’s spent everything in you.
>Turning the ancient tome to the page you desire you clear your mind and begin reading the text.
>It’s in a dead language, one that was killed for very good reason.
>This type of magic is forbidden, but your heat is getting to be unbearable.
>Plus, this is yet another means to test your magical prowess.
>Taking on a demon, even if it is just an incubus, may be considered excessive by some, but even if you don’t have the best looks you do pride yourself on your power.
>The ancient words escape your lips and the magic from your horn glows black.
>The summoning circle illuminates a very dark purple as the candles dim.
>Soon it’s the only source of the light in the hidden room.
>You don’t even feel the least bit spent as you reach the end of the summoning spell.
>A magical pressure rises from the circle at an alarming rate.
>There’s a roar as the candles reignite and send pillars of flame up towards the ceiling, blinding you temporarily.
>When you open your eyes once more you spy the fruits of your labor.
>In the center of the circle stands a demon.
>One with green flesh no less, not the deadliest tier of demons, but certainly not one to be taken lightly.
>You weren’t expecting him to be so androgynous, but you can pick up on his virile male scent immediately.
>Your nethers react accordingly, as your winking increases in pace.
>At this point you’re too desperate to care what he looks like so long as he can give you what you need.
>The small part of your mind that isn’t drowning in lust however is quite thrilled that you actually managed to summon a demon.
>A demon! Nopony since the language was thought killed has been able to accomplish this!
>But celebrations can come after you’ve quieted the hunger in your womb.
“I am Twilight Sparkle. Speak demon, tell me your name and your kind.” you command in the ancient tongue.
>The demon tilts his head, his long arms extend, bearing out his claws at you, and he belts a string of deep sounds and rumblings.
>HIs voice sounds so alluring to your ears, even if you can’t understand him.
“Can you understand me at all?” you clear you throat as the ancient language hurts to speak in, “Raise one your claws above your head if you can” you command in normal Equestrian.
>He instead chooses to pound his balled up claws against the magical barrier surrounding his circle.
>Okay so you can’t understand him, and he seems angry.
>However, he’s also covered from the neck down to his feet in clothing.
>Your can feel your arousal running down your inner thigh as you gaze him over.
>This has to be an incubus.
>Why else would he be dressed so alluringly.
>Your mind is becoming hazier, thoughts of him mounting you and spilling his potent seed deep into your thirsty womb flare up the more you try to dismiss them.
>A crack sounds in between the thumping of the incubus’ claws on the barrier.
>It snaps you back to attention and reminds you that focus is the key to keeping him contained.
>Redoubling your efforts, the crack in the barrier repairs itself.
>Need to find a quick way to get control of the situation.
>Didn’t expect the fact that you can’t command a demon if it can’t understand you.
>…That’s it!
>Your horn glows as you charge the phantom limb spell.
>Focusing the spell solely on your mouth, it passes through the barrier with not resistance.
>You can feel the softness of his clothing brush against the tip of “your muzzle”.
>From this close you can get a much stronger sense of his musk.
>It’s enough to send shivers down your spine, inadvertently raising your tail up high.
>Your phantom muzzle passes through his clothing until you can feel the warmth of his flesh against your lips.
>You’ve always fantasied about what it would be like, to be this close to a male.
>The warmth radiating from his groin is incredible, you wonder if it’s hotter than a stallion since he’s a dem-
>Oh stars and moon above, THE SMELL!
>He’s safely contained several hoofs away, but his scent is completely filling your mind.
>Your legs feel shaky, the fur along your inner thighs is soaked through with your arousal.
>Slowly, your lips part, and the phantom ones just before the demon’s cock do the same.
>You lean forward and extend your tongue, little by little.
>Until…
>The demon growls slightly and jumps back, placing his claws over the crotch of his pants.
>The taste wasn’t anything too special, he’s not even aroused yet after all, but everything about it felt so right.
>Your clit winks rapidly, desperate for more.
>Once more your phantom mouth passes through his clothing, pausing briefly to brush your lips against his warm claws and you take another lick of his demonhood.
>The demon inspects his claws for a moment before jumping in place slightly the moment you make contact with his privates again.
>What you assume is a gasp escapes his lips and he looks down at you.
>From his point of view it must look like you are merely licking the air before you, but from yours you are feeling a satisfaction that no toy has ever given you.
>You gently run your tongue along his flaccid member, lapping up every spot you can.
>Saliva coats your muzzle just as much as it coats his penis.
>The demon steps forward just as you were preparing to take another lick.
>The sudden motion catches you off guard and his demonhood enters your mouth.
>A seductively low rumble emanates from the demon’s mouth as he no doubt feels the sudden warmth of your own.
>You can’t help but moan at the sudden intrusion.
>Your wings flare out as you greedily take in his entire length.
>HIs claws pound against the walls of the barrier as they come to rest on it.
>You’d read that moaning was a great way to stimulate your stallion.
>While that first one was involuntary, these next ones won’t be.
>You ignore the tickling of his fur as it brushes against the tip of your nose and instead focus on extending your tongue to lap at his scrotum.
>Slowly you trace your tongue along his gonads, hoping that this coaxing him now will result in a larger load.
>One that will completely drown the desert that is your womb, turning it into a thick milky ocean.
*Crack*
>You open your eyes to see the demon looking down at you, the slight glisten on his brow gives you all the encouragement you need to know that all your studying and rehearsing is paying off.
>The investment in cucumbers was totally worth it.
>You apply a gentle suction to his cucumber, bobbing your head back and forth slightly.
>Enough that the tip of your tongue rubs the base of his cock before going deep to fully caress his jewels.
>Drool is pooling down by your forehooves as you let the magic mouth do all the work, your rearhooves are being pooled by a different thick fluid altogether.
>You find very quickly that going down is getting to be more difficult.
>Almost too difficul-
>You step back, withdrawing your phantom mouth from his cock and cough a few times.
>You weren’t expecting his full length to be that much.
>The back of your throat still tingles from the pressure.
>Wiping the mix of saliva and precum from your muzzle with a forehoof you glance up to the still secured demon.
>He’s dropped his pants to the floor.
>Your eyes go wide as you see him donning a much smaller pair of shorts underneath.
>It just covers his groin, to think that anything would wear such a lewd garment…
>There’s a very wide wet spot over the front of his shorts, and you make out the shape of his firm member against his shorts.
>Oh sweet friendship you think you can see it throbbing!
*Crack*
>You step closer to the barrier and guide your phantom over to him once more.
>It’s only when you’re this close that you notice the small button on the front of his shorts.
>Could this actually be for…
>You grin smugly as your phantom mouth undoes the button with, a formerly practiced, ease.
>Sure enough you can see a hint of green just beyond the lewd cloth barrier.
>Your wings stiffen almost to the point of pain.
>Using “your mouth” you coax the demon’s cock through the hole in his shorts.
>It swings upwards and slaps against the bottom of his shirt the moment your withdraw from it before coming down some and bobbing in place slightly.
>Your eyes are fixated on the otherworldly phallus, the cloudy fluid that coats its tip, its massive size and lack of ring, the firmness it must have to be able to defy gravity as it does.
*Crack*
>You fear what it is a higher demon would have if-
>A firm pressure makes itself known along the side of your cheeks and before you can even recognize it as the demon’s claws, his penis has already entered your mouth once more.
>Despite there being no ring, his member is quite thick the further along he gets.
>HIs demonhood taps gently against the back of your throat.
>You desperately circle your tongue around his head when he pulls back, lapping up as much of his pre as you can.
>Its salty taste is heavenly, and only makes your pussy contract even harder, desperate to milk him for everything he’s got.
>You watch him thrust the open air as his motions match the pressure inside your mouth, small grunts of pleasure escape his lips, with each one your pride swells.
*Crack*
>Your ears perk up and you note that your barrier is weakening.
>How long has it been doing that?!
>You try to regain focus and repair it once more, but the demon’s grip tightens along your muzzle and his thrusting increases.
>You want that thrusting to go elsewhere, you need his cock pumping your tight cunt.
*Crack*
>You need to end this quickly.
>Nulling the phantom mouth spell causes him to stumble forward slightly and also finally gives you the chance to regain your breath.
>Even fresh air is no longer satisfying.
>That’s not good, you’re falling prey to your desires, to his influence.
>You just need to get his release Sparkle, you can maintain the barrier for that long right?
>Right.
>Confident in your abilities, you do what no sane pony should.
>You show your desperation.
>Tail raised as high as your dock will allow, you back your soaked pussy to the barrier.
>The magical barrier feels cool, sapping some of the burning heat from your loins.
>The demon reaches a claw out towards you, only to be halted by the barrier.
>Your horn glows once more and from over your shoulder you can see his cock shimmer a faint purple.
>He glances down to his member and then to the purple barrier.
>Thankfully you don’t have to offer any further explanation as he drops to his knees right next to the barrier and puts the tip of his penis against it.
>The passage spell allows it to slide right through the barrier as though it were never there.
>His claws are placed high along the barrier as he leans into it to get as much of his demonhood out as possible.
>You want to squat down and take several more long licks of his delicious cock, but you’ve tasted enough through the phantom and you’re running out of focus.
>Using magic once more, you guide the tip of his head to your entrance.
>Your lips contract in line with the rapid winking of your pussy peppering him with lewd kisses.
>The demon grunts and shivers from the sensation.
>It’s a shame you can’t brag about pleasing a sex demon to any of the stallions you know without being brought to trail for using this magic in the first place.
>You take one shaky step back, his head enters just past your lips, eager to milk him already your walls contract in synchrony to attempt drawing him in even more.
>A loud moan emanates from deep within your throat as you impale yourself on his spear.
*Crack*
>You can feel the cool barrier against your tail hole, the stark contrast of temperatures from your pussy to your ass is enough to almost-
“Aah! Ha!”
>You can feel the splash back of some of your marecum against your rearlegs as you squirt so close to the barrier.
>The demon doesn’t halt as your orgasm racks your body with pleasure.
>He continues thrusting into your spasming depths, unable to work in unison under the electric bombardment of orgasm they simply contract randomly.
>The seemingly rapid change in “fullness” you feel as a result of your disorganized contraction only extends the waves of pleasure coursing through you.
*Crack*
>You focus only on breathing until you are able actually think again.
>Your body regains control of itself and you slowly start bucking back against the demon’s trusts allowing him to penetrate deeper than ever before.
>His cockhead plunges deep enough to touch against your cervix.
>Each union of your two organs sends shocks up your spine causing your wings to flap involuntarily.
>The pleasure is so intense that you can’t stop yourself from moaning.
>His own moans begin surfacing, having been coaxed out by yours.
>Each deep lovely rumble that emanates from his throat only amplifies your pleasure.
>Here you are, “Twiggy Piggy”, as those colts back in Canterlot called you, making an incubus moan.
>His thrusts increase in tempo, and you buck back faster to match it.
>Your wings flap more and more often.
*Crack*
>Your body feels lighter as the pleasure builds up in your depths.
>No wait, it actually is lighter.
>Your upper half is being raised off the ground by your wings.
>One more thrust has you throwing your head back as you back tightens.
>You let out a deep moan into the room, its echoes drown out the yelp you give when your now stiffened wings stop lifting you up.
>Your upper half slumps to the soaked crystal floor, while your lower half remains firmly in place.
>The thrusts stop, though he doesn’t pull out and you can hear a series of low rumblings coming from behind you.
>You wipe your nose with a hoof, yup, that’s a little blood.
>Turning back, you can see a smirk on the demon’s face as he continues making the low rumblings.
>Two rows of white teeth reveal themselves to you, and while you expected to see them, the sharp ones still send a pang of fear to your heart, and your blood feels cold for a brief moment.
>Its when you realize that the demon is laughing at you, rather than anything more menacing that you replace most of the fear with embarrassment.
“Aah!”
>A sudden thrust surprises you enough to almost fall to the ground completely, but it would seem your heat flustered mind knows where its priorities are, and getting this cock’s thick cum is the highest priority.
*Crack*
>You scoot your rear against the barrier once more and allow the incubus to do most of the work again.
>You were certain that incubi shoot vast amounts of cum in short periods without tiring, you, and your overworked cunt, were certain you’d be bathing in his thick spunk by now.
>The cool barrier and crystal floor were just the refreshers you needed to recov-
*CRACK*
>A surprised yelp escapes both your lips and his which are immediately followed by two firm slaps to your butt.
>Your upper half jumps to attention, while your lower half remains firmly planted where it can continue getting fucked.
>The barrier’s deteriorated enough that the demon’s claws broke through and struck down onto your ass.
“Oh no, that’s not go-ah AH!”
>HIs powerful claws kneed and grip your cheeks as his thrusting increases.
>Your pussy contracts even harder, feeling the energy of the incubus’ thrusts has only made your body put everything into keeping up.
>The squeezing is random, his claws grip with different strengths each time.
>You feel him grip hard enough so the sharp end of his claw rakes along the supple flesh beneath your fur.
>Your heart is racing as fear begins flooding your body.
>The feeling is so strong that even your rearlegs are willing to run in order to assure your survival, but you can’t move.
>His grip is too strong, his weight is too much.
>You’re pinned here, as he continues his powerful thrusts into your soaked pussy, with only a crumbling barrier keeping him form gaining any more on you.
>This is bad!
>But why then…
>Why does it feel…
>Your back arches once more, as another orgasm brings your body to a pleasured halt.
>You’re completely at his mercy now, the barrier is going to break soon and you’re stuck here getting off to the thrill.
>This is what he wanted.
>Of course they could control how often they cum.
>He was luring you with each previous orgasm, biding his time.
>And now he’s got you right where he wants you.
>And you like it.
*CRACK*
>The barrier has broken.
>The incubus uses his demonic strength to lift you back onto shaky legs, and then rates your lower half even further.
>Now in a standing position, the demon pounds into your backside without mercy, his hands grip you firmly around the flanks.
>Feeling the sweat and heat from his body as opposed to the coolness of the barrier that was there before adds just another level of pleasure.
>Soon your reduced to grunts that match each of his powerful thrusts.
>The room reeks of sex and your cum.
>Wet slaps of your body on his are the only other sounds in addition to your grunts.
>You have no idea how much time has passed since you summoned your master.
>Feels like five minutes, but it could’ve been as long as thirty!
>You find yourself feeling grateful that he’s chosen to continue using you rather than run off to bring far more attractive mares to their knees.
>He sets you down on the ground, if it weren’t for his unending strength holding you up, you’d fall in a heap of sweat and arousal.
>His firm claw wraps around your tail and hoists your lower half up eliciting a yelp from you.
>Using his other claw he guides himself into your tired cunt.
>You’ve cum so many times that your walls aren’t able to contract in any meaningful fashion.
>With each thrust he yanks your tail sending waves of fear, pleasure, and pain through your body all at once.
>The conflicting emotions only heightens your pleasure as he continues toying with you.
>Yes, toying, you’re nothing more than a plaything to him now and it’s all you want to be any-
“Aah? Aah! AAH!”
>His thrusting is faster than you can ever remember it being, and despite having only a five second memory now, you get the sense that it might finally be happening.
>He grunts loudly and grips both your flank and tail hard.
>His claw digs in deep, and you arch your back up once again.
>The incubus hilts deep, his cockhead kissing the entrance to your womb.
>And with one final loud grunt he cums.
>The flooding of his thick fluid into your achingly desperate womb is enough to bring tears to your eyes.
>He gives small thrusts as his cock continues pumping out his demonic cum, painting your inner walls white with his seed.
>The feeling of fulfillment deep within you, the extinguishing of the roaring flames of estrus with his milky load is the most wonderful sensation you’ve ever known.
>Unbridled relief floods through you, and with it comes the exhaustion that was only kept at bay by lust.
>You find the darkness taking you, and feel no fear as it does so.

>You awaken in the corner of your hidden chamber, a large black cloth lays under you with a small white cloth sitting near your face.
>There are some small red stains on it, you find yourself sniffing and feel the blood that dried on your muzzle feels like it’s gone.
>You glance around the room to find the incubus sitting nearby, he’s wearing only his shirt and pants now, which means that this cloth is…
>You rise to your hooves and he turns once he hears the clopping of your hooves on the crystal floor.
>He waves one claw similar to how spike would, in greeting?
“Uhm… th-thank you for cleaning up my nose… a-and giving me this to lay on” you respond as you float the coat and cloth over to him.
>He takes them in one hand and nods once.
>Oh right, he can’t understand you.
>The incubus sets the items down on the floor and motions for you to come closer.
>You take one step before flashes from before you passed out surface in your mind.
>You called him master…
>You’re such a fucking beta.
>Sheepishly, you trot over to him and see that there are some sheets of parchment on the floor.
>On them he’s made some kind of scribbles.
>No, not scribbles, they’re drawings.
>On one he’s drawn a small four legged figure with what appear to be wings and a horn, you, and there’s a taller figure, you assume to be him, trapped in a circle.
>There’s an arrow the leads to another scene of you facing away from him as he stands near the circle, he appears to be holding one claw in a fist but with the opposing digit pointed up.
>The next image is of you with a smile on your face and him standing in the circle again.
>The final image is of him standing before a very large building with that same “digit pointed up” pose.
>Could he mean the castle?
>D-does he want to live with you in the castle?!
>You hop giddily, no wonder he didn’t leave!
>The incubus gives you a questioning look, as far as you can tell.
>You point a hoof at him, then yourself, then the floor of your room and lastly to the image of the building, ending with a similar look.
>He looks between you and the drawings for a moment before shaking his head.
>Wh-what?
>He points to himself, then the summoning circle and you, and lastly the building image.
>Oh… he wants to return…
>You should feel ecstatic that the powerful demon you summoned through forbidden magics doesn’t with to attempt taking over this plane, but you can’t help but feel at least a little hurt.
“Okay, just go stand in the circle again” you mumble while motioning with a hoof.
>You stare at the ground as you hear him walk, a slight tickle by your ears makes you look up to see him petting your mane.
>He smiles down at you, and you can’t help but smile back.
>The incubus walks over to the circle and stands at its center.
>Your horn shimmers purple once more and you levitate the ancient tome over to you.
>Before you can utter a single word, the room booms with a voice that is both. nowhere and everywhere “TWILIGHT SPARKLE!”
>In a flash of blue light, Princess Luna stands before you with a furious scowl on her face.
>”Didst thou think thy couldst use one of our spell books without our knowledge?!”
>Hers?!
>”Thou art clever to have cast in in such a well isolated room, we were unable to discern the exact location of its casting until thou hath made the most foalish mistake of sleeping!”
>You can’t even speak.
>”Oh yes Twilight, we art fully aware of thine TREASON. Conspiring with a demon?! Thou art fortunate we have decided to investigate the matter ourselves… what would Celestia have done had she known?” she hisses.
>Luna glances around the room before settling on the incubus, “Aah, so this is the demon thou were willing to hoof the entire world over to, if thine dreams are any indication of this powerful… alluring… f-foul creature’s ability then it is clear that we art the only ones capable of… containing it.”
>You open your mouth to tell her that it actually means no harm, but she cuts you off.
>”Leave this room Sparkle. We shall… engage this demon ourselves to do what thou could not.”
“But Pri-“
>”BUT NOTHING!” she roars, “Thou hath amassed enough crimes to spend a thousand lifetimes in prison!”
>You swallow hard.
>”But we art willing to let this matter go by, just between us, if thou leaves this room forthwith!”
>Needing no other reasonings you scramble for the door.
>”Hold!” Luna commands just as you open the door, “Thou art also in charge of running our night court for the next six months.”
”Bu-“
>”DID WE HEAR SOMETHING?”
>You slam the door shut behind you.

>You are Anon.
>And assuming you didn’t slip into a coma while getting ready for work and are hallucinating this whole thing you’re fucked.
>You had trusted that purple lusty alien horse thing to send your ass back home.
>If she did it right then, you could’ve sprinted home, showered and changed, and maybe made it to the office in time.
>Your lazy ass is on your last warning and you really need this fucking job.
>Fucking doublecrossing bitch brought in one of her pals instead.
>And while that horse pussy was hands down the greatest pussy you’ve ever had, you’ve really gotta keep that job.
>You can feel a gentle caressing of your balls as the taller blue horse takes a few steps closer to you.
“Mother. Fucker.”
