Paper Pony Lewd

>It's a bright sunshiney spring day in Ponyville
>It's nice and warm outside with a nice breeze too
>It's the perfect day to go out and play, and by Celestia you were going to play with your sister!
>Origami had locked herself in her room for the past few days, hardly ever coming out
>You vaguely remember her doing the same last year around the same time too...
>Oh well.
>The clip clop of your hooves vertebrate off the wood floors of the house as you trot to your sisters room
>You bang on her door
>She hates it when you do that
>Oddly though instead of immediately replying with an aggravated tone it takes a moment before you hear a subdued "Yeah?" from inside the room
"C'mon sis! You've been in your room for, like, DAYS! Can't we play together or something?"
>There is another pause, this time the silence goes long enough that you almost speak up again but before you do so you hear her hoofsteps come to the door
>She opens the door and peeks her head out, "Play... together?"
"Well duh. Say sis, you look kinda red."
>"Oh, well, uh", she stumbles over her words for a moment, "Say, why don't you come into my room and... we can play something in here?"
"But sis! I wanted to play outside!"
>Papermint bites her lip for a moment before saying "But there's something fun we can do in here! Come on, you'll really like it!"
>You curiously eye her up for a moment
"You sure?"
>"Super sure."
"Okay then."
>At that she opens the door fully to let you in
>Immediately as you enter your sister's room a weird smell hits you
>It's kinda nice in a weird way
>You hear Origami shut and lock the door behind you before walking past you and hopping onto her bed (which was a total mess) and sitting on her hunches
"Now what? What are we going to play?"
>"Come up here and sister will show you.", she says with her forelegs open for a hug
>You run and jump onto the bed and into her embrace
>She's very warm and that smell is really strong now
>Is it coming from your sister?
>After hugging for a moment she flips you around and starts rubbing your belly
>Always one to love bellyrubs you close your eyes and let her pet you
>This goes on for a few minutes
>Her hoof going up and down, up and down, up and down
>But now it's a little lower than before
>And then lower
>And lower
>Your eyes spring open as her hoof nudges your sheath
"S-sis!?"
>"Shhh, this is a part of the fun.", she says
>You gasp sharply as her hoof begins kneading your sheath
>It kinda feels like it tickles but it's different, you're not sure if you like his new feeling
"Sis... stop..."
>Your complaint is quiet and weak, cut off by gasps
>You can feel your small shaft swelling
>Papermint removes her hoof and fondles your balls and she watches in absolute excitement as your young member spills from it's sheath bob as it slowly stiffens
>As soon as your completely erect she takes in in her hoof
>The mere touch makes you squeak
>You turn your head up to look at her but your eyes go wide as she kisses you
>But this kiss doesn't last as she starts massaging your cock
>You give a little grunt very time she stops at the medial ring
>She then begins to speed up her minstrations before suddenly stopping
>Before you have the chance to question it she shifts your smaller form and lays you out on your back
>From your position you look down past your hardend dick to your sister whose face is very flushed and looking into your eyes as she has the hoof that wasn't working your shaft between her own hindlegs
>Your dick bobs as you notice that smell in the room is stronger
>She gives a grunt before removing her hoof from her crotch
>It's wet and dripping fromsome sort of substance
>You moan a little as she rubs the flat head of your cock with the same hoof, smearing it with the odd liquid
>She then climbs over you and your eyes meet as she says "I need you, little brother."
>The only warning you get is something dripping onto your nethers before Origami's hoof directs your shaft into something hot and wet
>She "ahhs" as she lowers herself onto you
>The feeling is so intense you do nothing but throw you head back and pant as you instinctively buck your hips, wanting more
>She slowly slips down your rod before finally giving a coo as she totally hilts you inside of her
>For you, the feeling is indescribable
>Her hot insides squeeze and constrict your cock
>She lifts herself off of you before quickly coming back down
>Both of you grunt from the pleasure before she goes at it again
>You moan loudly and hold onto your sister's flank as she bounces on your member
>"I love you little brother.", she says
>As she goes faster all she says is "I love you" betweens her screams and moans
>You feel something building up
"S-s-sis!"
>"Inside me! Inside me!", your sister shouts
>"Make me pregnant little btother!"
>She punctuates that as she hilt down on you and grinds against you
>You can't take it and shout as you flare inside of her and spurt load after load straight into her womb
>She gives a final scream of bliss as she cums down hard on you
>Soon she's laying atop you, both of you breathing heavily
>It's kinda uncomfortable but you don't mind much
>You can still feel yourself inside her as you eyes grow heavy and falling into sleep
