>the only light in the room came from the crack under the door
>I huddled in a corner, feels safe having walls at my back
>they don't actually help me any, but they make me feel better temporarily
>I think it's some sort of basement, there's no windows to look out
>I've lost track of time since I had been captured after being forced into this strange world
>laying on my side, I could see if anyone came to the door
>it gives me time to brace myself for when she comes
>how long had it been since her last visit?
>was it 6 hours?
>no, it was 10...
>or was it-
>I stopped, eyes widened as I saw a shadow blocking some of the light from the crack
>the instant the door flew open, I was blinded by the light from the outer room
>my captor galloped into the room, excitement rising in her voice
>I turned my face to the corner and covered my face to block the light
>there was nothing for me to grab on to
>resistance was futile
>I felt the floor beneath me fall away as I was once again lifted into the air by her magic
>she was still babbling on about something
>it wasn't anything I could understand
>I heard the voice of the little dragon saying something to her
>she stopped and looked at me curiously, before almost embarrassedly responding to the small dragon
>I was still floating in the air, her magic enveloping me
>she kept me just out of reach, she learned the first time she picked me up with her magic, however long ago that was, that I'd strike out at her
>punched that bitch in her stupid horse nose when she found me taking refuge in a cave
>I don't know what happened after that, just that I woke up in this room, with the door locked
>since then she would come in every day
>every single
>god
>damn
>day
>she would prod me with her magic in various ways
>she even took a blood sample once!
>and she would sit down in front of me and attempt talking to me
>that wasn't the case today, though
>she looked me in the eye and her horn glowed brighter than ever
>I don't think she was expecting the results she got
>for a split second I saw a look of shock cross her face
>the force of the magic threw me against the wall behind me, stunning me for a few seconds
>I pushed myself up, my hands and feet starting to feel numb
>I only managed to get into a sitting position
>across the room the unicorn was in much the same position as myself
>she didn't hit the wall, but she landed on the floor
>she got up and ran over to me, seemingly concerned
>she was talking rapidly and looking me over
>my legs and upper arms started feeling slightly itchy and it felt like someone was pulling on both of my ears
>probably that damn purple horse
>I looked up at her to see a concerned look on her face, her horn wasn't glowing
>which means she wasn't actively doing it, must be that spell she cast
>she urgently issued a command to the little dragon
>she said something about a book
>wait, what?
"Did you just-"
>I was cut off by a pain shooting through my face
>I grasped for my face with both hands only to find I no longer had hands
>instead I was prodding my own face with two new hooves complete with silver-grey fur
>I managed to glance at the purple unicorn who was already frantically flipping through the pages of a book
"No, no, no. This shouldn't be happening." she worriedly groaned
>even with my jaw slowly extending outwards into what I can only assume is the muzzle of a horse I managed to shout something at her
"What did you do to me?!"
>I was caught off guard by the slightly feminine sound of my own voice
>both the unicorn and the dragon looked at me, then at each other
"Well, at least we can understand him now." The dragon stated nonchalantly
>the horse glared at him for a moment before turning her gaze back to me
"I'm so sorry! I didn't mean for this to happen! The spell was only supposed to make you understand our language!"
>I felt a pulling sensation at the base of my spine, the same kind of feeling you get when you pull your finger
>an appendage was growing and it was uncomfortably pushing against the ass of my pants
*RIIIIP*
>I turned to see a tail of navy blue hair flowing out of my pants
>my feet had already turned to hooves as my hands had, but my legs were still changing
>What used to be my ankles rose higher and higher on my legs, all the while my pants ripping along the way for my new, thicker, ridiculous horse legs
>my ankles stopped just above where my knee used to be, which itself had risen above that
>by my recollection, my entire lower half, as well as arms and head were that of a pony by this point
>the clothes were becoming increasingly constrictive, I started biting and pulling at them almost instinctively
>as I was just about done pulling the tattered remains of my shirt off, which was still being ripped as my torso started forming into the barrel-like body of a pony, I felt a shock through my entire body
>the air itself felt as though an energy was flowing through it, into me through a spot on my head, by my hairline
>I felt an awkward rubbing feeling, coming from that spot
>reaching up with a hoof, I felt the area to find a horn that had just finished forming
>I still had a warm, shifting, feeling in my gut
"Uhh...is it over?" I tentatively asked
>the unicorn, having given up on her books trying to solve the issue, looked at me sympathetically
"I-I don't know...That wasn't even supposed to happen." she replied
>I looked over my new equine form, noticing I began to tremble
>the warmness migrated from my gut to my crotch
>within seconds, the feeling exploded into powerful sensations flowing over my body in waves
>my new legs gave out beneath me, dropping me to my knees
>I shuddered and moaned, before I reached down to rub myself before I remembered I no longer had hands
>I looked down, only to see my dick shrinking
>I jumped up, shocked at what I had seen and started shouting
"DO SOMETHING! STOP THE CHANGES! MAKE ME A HORSE IF YOU NEED TO, BUT DON'T TAKE MY DICK!"
>the unicorn who shared the room with me jumped back, startled
>her horn began glowing, as did I in the same colour as her magic
>I felt a surge of energy briefly, but it passed quickly as the glow faded
>no change
>my legs buckled again and I fell into a laying position
>the sensation became overwhelming
>I won't lie, it felt amazing
>unable to resist the urge, I reached down with a hoof again and rubbed myself
>my dick had vanished by this point, it was awkward trying to rub my new clit with a hoof
>but it got the job done, not to say the change itself was responsible
>I shuddered and moaned again as I came, getting my hoof damp
>I looked around the room to find the purple unicorn had vacated, probably when I started masturbating
>I breathed a sigh of lazy contentment, exhausted from the transformation
>too tired to deal with the changes right now, I dozed off
>at least if I was stuck in this world, I was gonna fit in
 
--The Next Day--
 
        I awoke in the early morning on a rather comfortable bed, with the sun shining in my eyes. She must have moved me after I fell asleep and covered me with a blanket. As I sat up I noticed my hooves and the rest of my new body and jumped in shock, having forgotten the traumatic events of the previous afternoon. I groaned and flopped back onto the bed, covering my face with a hoof.
        It wasn't a horrible dream, she really did turn me into a fucking horse. A moment later, I heard a knock at the door to what I can only imagine was a guest room. I'm sure it's her and I'm sure she cares more about my well being now that I'm one of them.
        I sighed "Come in" I groaned.
        The handle glowed purple briefly and the door opened slowly and she poked her head in looking at me before fully coming into the room, her head warily lowed.
        "I suppose I should introduce myself before I apologize for...Yesterday." She looked sheepishly looked up at me.
        I sighed once again. "Yeah-" my voice caught in my throat when I heard it again. "...Yeah, fine."
        A nervous smile crossed her stupid horse face. "I-- My name is Twilight Sparkle. I never meant for this to happen to you." She paused for a moment before continuing. "I only wanted to communicate with you, I've never seen a creature like you before. I-I wanted to learn all I could about you."
        She seemed to genuinely feel bad about her mistake, but that doesn't change the fact she kept me locked up in a darkened room for what I assumed was 22 hours a day. "Okay..." I started, before thinking a moment on where I'd take this. "Mistakes happen, I understand that, I guess...I'm still not particularly happy  about this situation. Here I am, on an alien world, in an alien body and suddenly a girl."
        This seemed to pique her interest. "Alien? How do you know? Maybe you're just from a far away land with no knowledge of Equestria?"
        "Trust me, if there were a land populared by magical horses on my planet, we'd know." I replied. Somehow, I had managed to stay calm. The question was burning in my mind and I had to ask it. "Why did you keep me locked in a lightless room for...however long it was you kept me there?"
        This seemed to catch her off guard. "Err...I had assumed it was your natural habitat. I observed you coming and going in the night for weeks before I approached you. Besides, I only had you here for three days."
        I didn't even know how to respond. I guess that's how it might have appeared to her, if she was really watching me for that long. There was an awkward silence before she spoke up again.
        "Despite that it's my fault you're a pony now, I hope we can still be friends. I would absolutely love to learn about your people." She held out a hoof to me, seemingly as their equivalent of a handshake. I hesitated a moment, then held out my hoof and shook hers.
