"Anonfilly Summons a Tentacle Beast"
---------------

>You went through a lot when you first landed in Canterlot as a unicorn filly.
>After copious amounts of running, swearing and scolding you were taken in by a unicorn couple.
>Once you had managed to settle down in your new life, you found out you were really good at magic.
>You got turned into a tiny girl horse, but the magic makes up for it.
>You’re apparently pretty good at it.
>You eventually got used to your new form.
>Except for one thing.
>Becoming a filly meant getting fillybits.
>And right now those fillybits are doing their best to make your life a living hell.
>You flinch as your pussy winks again, exposing your hot insides to the world.
>You read through the spellbook in front of you faster.
>There’s got to be some kind of spell to deal with this.
>You’ve been told it’s normal to just find a colt and use an anti-pregnancy spell.
>But fuck that.
>You aren’t going to let a colt near you like that.
>A colt with a big, throbbing horsecock that could easily end your suffering…
>You groan as your clit pops out again.
>You need to find a spell for this before you actually do go out and get a colt.
>Even if you don’t know any colts.
>Or very many fillies.
>...Shut up, you’ve been busy with studying.
>And speaking of studying, you have a spell to find!
>You snuck this book out of the adult section of the library.
>It has spells all about sex and love and anything relating to those things.
>If there isn’t a spell in this book to help you, there won’t be one.
>Giant cock, always wet marehood, hypersensitivity...
>Useless to you.
>Fertility spell? 
>Dear god no.
>Want-it-need-it?
>Might be fun to learn later.
>Heat-be-gone?
“Spell for mares in heat... yadda yadda… will deal with the effects of heat for a year… perfect!”
>You knew there’d be a spell to deal with it!

“Let’s see… huh, not that difficult. Just need to draw a few runes on the ground and stand between them.”
>You wonder why this spell isn’t more popular to deal with heat?
>Whatever, you just need to get this spell ready now.
>Several hours later you’re finally done.
>You snuck into the basement to draw out all these runes for the spell.
>You had to be very careful with drawing them.
>One small mistake could have huge consequences.
>Your fillyhood didn’t help you at all during this process.
>The constant winks and the burning sensation in your nethers made it hard to concentrate.
>The inside of your thighs are covered in your femcum.
>But soon you won’t have to worry about heat anymore.
>You won’t have a burning void inside you begging to be filled.
>You won’t feel the need to have a colt climb on your back, push you to the ground and jam his-
>Gah, time for the spell!
>You walk between all the runes and light up your horn.
>You flow a bit of magic into the nearest rune and start charging the spell.
>Once the rune has filled with magic, it quickly jumps to the rest of the runes.
>It only takes a few seconds for the spell to be ready to be finished.
>With one last burst of energy you cast the spell.
>There is a bright flash of light that causes you to close your eyes.
>The burning in you is still there, so your heat isn’t gone yet.
>You didn’t screw up the spell, did you?
>You open your eyes a look to see if anything has changed.
>The runes are still glowing, so something must have happened.
>But what?
>You start to look around when you notice something just below your head.
>A flower?
>Why the fuck is there a flow-
“Gah!”
>The flower cuts you off by squirting a cloud of dust into your face.

>You cough as the powder gets into your throat.
>What kind of spell is this!?
>As you try to clear your throat, you feel yourself heating up more and more.
>You let out a moan as your pussy clenches tight in need.
>Oh god, your heat is getting even worse! 
>You try to take a few steps back, but can’t seem to move your hooves.
>You look down and see vines wrapping around your hooves.
“What the fuck?”
>They wrap your hooves even tighter as they start to climb up your legs.
>This can’t be what this spell does.
>It can’t summon a tentacle monster!
>It was supposed to get rid of your heat!
>You try to pull away from the vines, but they have you held tight.
>The vines covering your back legs creep further up and you feel them rub against the wet parts of your thighs.
>You can’t help but moan at the contact.
“Oh god.”
>That’s what it meant by getting rid of your heat.
>You can’t be in heat if you’re pregnant!
>You need to get this thing off of you!
>You start to charge up your horn to escape.
>It seems to have expected this as one of the vines whips out and wraps around your horn.
>You moan as a bolt of pleasure runs through your body.
>Your pussy winks again at the pleasure.
>You have to get out of here!
>You start to pull even harder at the vines and try thrashing around.
>The vines have you held tight, and you can do little more than wiggle in their grasp.
>One of the vines finishes its journey up your hind legs and brushes against your vulva.
>You wink in response as another groan escapes your lips.
“Let go of me you - Mmgh!”
>A vine quickly shoves its way into your mouth and cuts you off.
>You reflexively try to cast another spell, but the vine on your horn twists around it, causing you to shudder and moan again.
>The vine has some kind of sweet liquid coating it.
>It tastes kinda nice…
>No!
>There’s some kind of aphrodisiac on the vine.
>You have to get it out of you!

>You bite down on the vine, but it has a sponge like texture that just squishes as you bite.
>A flood of the aphrodisiac is expelled from the vine. 
>Your jaw slowly relaxes as the liquid enters your mouth and you swallow it down.
>Why were you trying to bite it again? 
>It just wants to help you with your heat.
>You should really get more of it.
>You start to suck on the vine, trying to get more of that tasty liquid in your body.
>Heat starts to pool in your stomach before moving backwards towards your fillybits.
>The vine back there runs over your mound again, pleasure coursing through your body.
>You’re winking near constantly now, and the need to be filled is overwhelming.
>You hump against the vine as best you can, but it stays just out of reaching, teasing your burning nethers.
>You whine against the vine in your mouth and start running your tongue over it.
>Maybe if you does this it will fill that void in you?
>The vines surrounding you start moving and you feel yourself lifted off the ground.
>They turn you so you are leaning back, your underside exposed.
>Still the vines at your nethers just brush against you, causing the burning to grow stronger and stronger.
>The vines turn you so you are pointed towards what look like a giant flower bud.
>The vines pull you closer and the bud opens up.
>What you see makes your eyes widen.
>There in the middle of the flower is a huge tentacle, easy three times as large as all the vines.
>You get pulled closer and closer to that monster.
>Your pussy clenches in want.
>You want that beast inside you.
>You need that beast inside you!
>The creature seems to have the same idea as you are pulled right up against that tentacle.
>The side of it grinds into your cunt, driving more moans out of your stuffed mouth.
>Please, just put it in!

>Two small vines rise up from the base of the tentacle.
>They have small suction cups on them and they move until they are hovering over your belly.
>They quickly dart down and latch themselves onto your teats.
>You scream in pleasure as they start pulling and twisting your teats.
>Your cunt burns with desire, your clit almost constantly winking.
>Why won’t this thing fuck you?
>Why won’t it-
>You shriek as an orgasm rips through your body as you are impaled on the tentacle.
>Your pussy squeezes as hard as it can, trying to pull the tentacle even further in you.
>The creature doesn’t care at all, and the tentacle continues to piston in you as you cum.
>You eventually come down from your high, but the pleasure does not end.
>The tentacle is filling your tight little pussy, stretching it to the limit.
>You don’t feel any pain despite just having your hymen torn and your cunt stretched so wide for the first time.
>All you can feel is pleasure as the tentacle continues to piston in you.
>You are so concentrated on the tentacle fucking you that you almost don’t notice pressure on your backdoor.
>A second later another tentacle push through into your ass.
>All you can feel is ecstasy at this point.
>All the tentacles ramming into your body pushes you into another orgasm.
>As you cum a second time, another suction cup vine lashes out and clamps onto your clit as it winks out.
>You shriek once more as a third orgasm hits you.
>You are in a state of constant pleasure.
>You soon feel the tentacles start to swell inside you.
>Yes!
>They’re going to breed you!
>You moan and try to beg it for more, but the vine in your mouth stops you from saying anything more than muffled moans.

>They piston into you a few more times before they push themselves in as far as they can without hurting you.
>They hold themselves in you and pulse a few times before finally spewing forth their bounty.
>You greedily gulp down the cum that flows into your mouth.
>Every time the tentacle in your pussy pulses and fires another shot of its life giving fluid, you feel it impact the entrance to your womb.
>It almost feels like it’s being shot straight into your womb!
>Alas, all good things must come to an end.
>The flow eventually slows down and the tentacles pull themselves from your body.
>The vines gently lay you on the ground as you softly moan, fluids dripping from your holes..
>You reach your forehooves forward and rub your bloated belly.
>With all the cream pumped into you, it looks like you’re already several months pregnant.
>You barely notice as the vines all pull back to the flower before slowly fading away.
>You just lie there, a deep sense of satisfaction flowing through you.
>Your nethers aren’t burning in need anymore.
>The spell did what it said it would.
>It got rid of your heat.
>You idly wonder what sort of creature you’ll give birth to?
>Is it going to be a pony, or some kind of plant creature?
>It doesn’t really matter.
>Either way, you know what you’ll be doing again next year.
