>You're tired
>You could deal with hiding from Pinkie
>Even thought she always seemed to know where you were but played along
>Damn Pinkie sense…
>Still, you managed to survive Pinkie's advances
>But then Twilight started to change
>In the little things that she did, throwing innuendos here and there…
>Until one night you got back to your room to see her sitting on your bed with a massive dick
>That shit oughta be as big as your head and as thick as your hooves
>She seems to be deep in some fantasy so you slowly backpedal away
>But being a bit awkward with your horse body movements, your back legs trip on themselves and you fall down
>Immediately you're encased in a purple aura and floated inside
>It wasn't the first time you were >Raped, pank must've done it like 3 times
>But Twilight…
>The one who told you to think of her as your own mom
>This feels way more personal
>"So what have we got here? Has a little filly been snooping on her mom?"
"Twilight you're not my mom, just, please, put me down and lets talk about it"
>"Oh no, snooping fillies need to be taught a lesson, and I know just how I'm gonna teach this one"
>When she finished her member twitched and seemed to grow even bigger
>It wasn't even hard and it was the size of your head before
>She's gonna fucking break you
"Stop that Twilight, first of all dicks probably shouldn't get that big, secondly you're a mare, so you don't even have one"
>You move a hoof to swipe at the area where the illusion is supposed to be
>But it's met with a very real, hardening cock
>One and half times thicker than your hoof and almost as big as your whole torso
>Sure, it's like half of her torso for her, but you're still a filly and everything's bigger for you
>You can't really process the information, so you just stay still floating over it as Twilight gives a low moan, your hoof stuck extended and holding it
>"Such a smart filly, you make me proud, but you forgot about one thing~"
>Your paralysis is slowly filled with fear of the very real thing ahead of you, trying to cower away while still being levitated by Twilight
>"Magic. And today has been a very tiring day you see, so I gave myself this to relax and unwind, but now that I caught you snooping…"
>Slowly she lowers your body on top of her own, before grabbing you with her hooves and pining you in a pseudo hug
>But from the position you ended in the tip of the beast is scratching your chin
>And you can feel the rod going all the way down below and no doubt even further
>You're going to fucking die
>No wait, priorities
"This is fucking gay Twilight"
>You say that in the most monotone voice you can muster
>But your body shivers both in fear and anticipation
>"Well, if I can teach my filly some manners with it, then who's going to stop me?"
>It's less of who's going to stop, and more about if it's going to fit
>Although you don't dare say that out loud
>As soon as she said it she rolled over, making you slide off and along her form
>But not wasting much time, as soon you were out she pinned your hooves to the bed with her magic
>You were stuck in a presenting position as she moved to your back to have her ways
>As soon as she touched you you knew you were doomed
>Even without looking you could feel that the thing almost went halfway across both your cheeks
>On Twilight's side though, it completely covered your filly pussy
>She prodded a bit, hoping it would widen just enough for her to go fill it
>But for you it was like trying to fit her own hooves straight on
>Then she dropped from you with a heavy sigh, and you knew you'd live to see another day
>"Buck, if I only expected you around I'd have given myself an smaller one"
"IF? I-I mean, uh, can I go now, you know, so you can masturbate in peace?"
>"Anon! I'm not masturbating I'm…experimenting something for stressful days, and I just know now how I can teach you not to snoop around your mom personal business"
>And with that she moved to your front, using her magic to lower your head
>"Open your mouth"
"What?! Fuck that, fuck this, fuck yo-"
>And then she slammed the cock on your face
>It went for a boop as you were saying "you" but it was just the right angle that it forced your mouth open
>And while it did fit, it was too big for you to breathe through
>"There, now momma can teach her filly her lesson, and maybe even clean her dirty mouth while we're at it"
>And so Twilight started moving it back and forth, its motions almost pumping the air you needed from your nose
>But she wasn't even going a quarter down before reaching your limit on her flare
>Because of that, it didn't take long before she tried to force her way deeper
>She moaned loudly while you screamed as the way got tighter and tighter
>Yet she managed to get it down to her ring
>But there was still another half mast to go yet
>She kept her motions smooth, while your body got used to the massive invasive member
>And after a while it didn't even hurt anymore
>Fucking magical horse body
>Noticing the way clear, purple made another attempt at going deeper
>She made three quarters in before she stopped again
>You'd guess she managed to get all the way from your mouth to your stomach now
>But from her moans and continued movements maybe that was enough
>It was only now that the idea of biting it came to mind
>But your mouth was so wide open that you had no strength to it, now feeling pretty much like a cock sock
>Meanwhile Twilight kept her rhythm in your mouth, shivering in pleasure
>It wasn't long before she came, deciding to do it deep inside
>Maybe deep inside didn't do it justice, as you felt her stuff flow straight down to your tummy
>It kept flowing for a while and you felt heavier as your belly grew a bit from 'eating' so much
>Finally, Twilight was done
>Slowly she removed the already shrinking monster from inside you
>When it finally came out, it did with a loud pop
>You couldn't help but cough, bits of semen flying out each time
>"Good fillies don't spit! Do you want another lesson already?"
>You couldn't talk without feeling like spitting some out or even puking it all
>Yet you did your best to lick what was spit from the coughs, in fear of having to deal with the monstrosity you somehow just survived
>Twilight on her part gave a content smile as she moved out of the bed
>"Good, that was your dinner by the way, but maybe momma can give her filly some milk as desert since she was so behaved"
>Then, feeling the spell keeping you stuck in place drop, you fell to your sides and just stayed there, unmoving
>Twilight on her part, took off the sheet and covered you with new ones
>"Or maybe we can keep that for another day, a nap is good for fillies too"
>With a good night kiss she went out, closing the door behind her
>Where s Pinkie when you need help against foal fiddlers…
[spoiler]>"Weelll, I was thinking on joining in, but did you see the size of that thing? Even I wouldn't want that close to my pooper, and the way you took it was just incredible! You need to teach me that sometime, oh, oh, how about tomorrow or maybe the day after?"
