>You walk over to the mirror and look at yourself
>You check your butt for your cutiemark..it's there but it isn't yours
>Then you look at your entire body
>Your mane is green,and your body..is blue what's going on
>Wait a moment..you aren't blueberry are you?
"Blue!!"
>You shout over for your filly lover and you only see...yourself.
>"uh what's going on sandy?"
"I'm you?!"
>"Wait what?"
"Here take a look into mirror
>You are bluberry,or so you belive.
>You walk toward the mirror and see...sandstone
>But that's impossible
>You turn toward your lover..or yourself?
>"Uhm sand,how did this happen"
>The blue mare looks at you
"I got no idea blue,i just..kind of went to bed woke up and..yeah"
>"Well we both went to sleep in my house right?"
>Gosh it feels so weird speaking in a deeper voice than your normal,bet sandstone feels the same,being a lot squeakier
"Yep after a fairly long night,we didn't drink anything that could have caused this did we?"
>"Not that i know of,but somebody might have cast magic on us"
"You mean in that night club?,i dunno..why would anyone do such a thing"
>"No idea..so how do we uh revert to normal?"
"Well i'm a batpony now so i can't exactly do magic..you'll have to read books on it so get to it blue!"
>"Uhm..okay blue..i'll uh read all those books..."
>You look at the dozen of books thrown on you and balance trying not to fall off,you walk over to the nearest room and sit down starting to read through
>It takes you a couple of hours and by that time sandstone is already gone..just hope he doesn't do anything crazy with your small body
>You aren't a unicorn normally,so stopping objects from hitting you is out of question
>And he probably can't use the natural bat agility..
>You read through each and every book on "transformation and body change magic" but none of them mention swapping filly bodies
>Altough one does mention that the two parties should copulate,and if they orgasam at the same time the next morning magic would revert
>With the risk of one of them becoming pregnant,using any forms of contraception will stop the spell from working
>You hear a knocking on door and you walk over to open it
>Sandstone,or better said YOU is waiting there
"Heya blue,i got us some icecream,and did you find anything out?"
>The blue filly asks you
>"Erm kind of..i found a book which might have the solution"
"Do tell!,we need a way to fix this before our parents find out that we somehow switched bodies!"
>You blush heavily and it looks a bit silly on you being a colt.
>"W-well it says we need to "fornicate" with you-i-mean me finishing inside.."
>As you say out those words you can feel something slowly grow between your legs
>That's not normal..
"Well that's hardly an issue to you blue,now is it~"
>"N-not really..a-alrigt..but please be gentle i-i never done it as a colt"
"Oh don't sweat it,it's not going to hurt at all,remember we did it once,why should it hurt now?"
>"I guess..i-i just don't know how it works"
"Well that's hardly an issue come on i'll show you"
>Sandstone walks over to the room and lies down on his back spreading his hindhooves
>He's a little bit too eager..you'd be much more shyed away from this..
"Now just..walk over to me and i'll lead you from there"
>You walk to the top of the bed and lie down on top of sandstone
"Good girl..well we could do the warm up if that makes you feel comfortable?"
>"Uhm okay.."
>You back away a little and place your lips on sandstone's marehood-however weird that sounds"
"Aha!,that's a way to go,now,you know how you would pleasure a colt,but this is gonna be a bit different~"
>"A-oki!"
>You push your tongue inside her wet folds and lick all around from inside
>You then take your other hoof and gently put it on her marehood,slowly circling it as it starts winking
"Ooh! You're way better than i thought you would be blue!"
"And gosh,is this how you girls feel,it's pretty a-amazing!"
>You push your tongue out of him,still teasing her clit.
>"Bend over cutie,i'm feeling really hard down there and i too want to have some fun you know!"
>"Normally you'd rush me,and now i'm gonna rush you!"
"Hah,alright but just this one blue,i want to be the dominant one!"
>You take your hoof off his mareclit and she turns over presenting herself to you
>"Well uhm..how do i"
"Bite me on the fur,you don't want to lose grip on me,trust me you are going to get rough with me,but it won't hurt or anything"
"Or atleast YOU didn't complain when i did it!"
"S-shut up sand"
>You blush.
"Ahaha,don't worry about it it's all gonna be fun!"
>You turn your face toward the now presenting sandstone and close up on her,lining up your erection with her fillyhood
"Ah,you seem to get hang of this,good,now as i said bite on my neck fur it's absolutely necessary"
>You do as told,close your face up to her neck fur and bite down hard on it
"A-ah!,that's very nice! and you didn't even begin!"
>You inhale the smell of your own body and it arouses you badly
>You need this,you want it!
>Sandstone shoots you a look and nods,confirming she's ready
"Go cutie,push it all in!"
>You tease her fillyhood lips a little before pushing your cock inside of your lover
>You don't even care how weird it is right now,you are male and he's female,it doesn't make a difference."
"Ahh!!"
>"D-does it hurt sand?"
"Not at all! If anything it feels amazing! why are you so uneager to do it more often blue!"
>"W-well you see...i don't really like sex all that much..the mess inside of me is hard to clean up.."
"W-well you won't be having any mess to clean this once,come on start thursting y-you aren't just gonna stay in me are you?"
>"I-it's also so tight,i feel like..my special part is going to get crushed"
"Oh stop worrying,it's normal,just keep going! please!"
>"O-ok sandstone"
>You take your cock outside of him and then push it in again repeating the same motion rythmically
"Aaah..that's so nice blue! you're ever better at this than i thought!"
>"W-why thank you sandstone b-but i'm feeling like peeing"
"Already?,awh you haven't even gotten me off..oh well just...enjoy yourself this is a one time thing,enjoy being a male!"
"Well just keep going,and go faster if you want the feeling to go away!"
>You listen to him,and start thursting in and out of your..once male lover.
"N-nice job blue! last a little longer for me!"
>You try your hardest not to orgasam while thursting quickly in and out of sandstone,but nature has different plans and you start cumming inside her painting the inner walls of your lover white
"Ah!! so warm~"
>Your thursts slow down and sandstone starts rubbing her winking clitoris furiosly with you still inside
>And before you can pull out she is finishing as well!
>Your cock stays locked inside of her as she orgasams milking you out of your last drop of cum
"Ah!~ W-way to go blue!,you are an amazing lover!"
>After her orgasam finishes,you are covered in mare juices and you fall on your back exhausted
>Sandstone turns toward you and teases
"Haha,a cutie like you can't handle being a male,well that's understandble you are going to get a very good sleep now,and wake up as a filly!"
"Hope you had as much fun as i did,even though i had to guide you through most of it,you silly colt!"
>"A-am not a colt am a filly~ you drag the word out as you close your eyes and fall asleep with a dumb smile on your face"
"Ah..being a filly sure is a lot easier..but i love her the way she is,it was a fun experience nonetheless"
>You sit up and rub your fillyhood a bit watching the cum drip down
"Hehe,no wonder she has so much fun with me,all the warmth inside of you..just divine it's all over my belly mhhm"
>You walk over to the toilet and take a piss,hoping to wash down all the cum,you wouldn't want blueberry ending up pregnant because of the little experiment
>Then you walk back to the bedroom and lie down next to the exhausted blueberry.
>You don't feel particularly tired,despite having a earth shattering orgasam,so you just sit there and wait for the day to pass.
