"Delivery for you!" said my Mistress Rashida, calling into the building from the street, as she used the reins to draw me to a stop outside the office of one of her elven clients. I stood on my two powerful hoofed legs and brought my hand-hooves to rest on the end of their short chain in display posture, lest I feel the whip again for forgetting.
"I'll be right down," said a voice from the first floor window - I think the place was some kind of legal practice.
I stood poised and still as I had been trained in the week since I'd cast the spell, the week since I'd been taken by the elves through their portal, to what I thought would be the life of a no-holds-barred sex-slave, serving forever in the elven queendom. I'd had ponyboy fantasies, sure, but the day after my eighteenth birthday, when I knew I was finally ready to cast the spell and let them enslave me, well, I guess I just never even considered that those fantasises would end up being my entire life.
My mistress's client emerged from her offices onto the wide, stone-paved street and reached up to the cart to accept the package my mistress had couriered over from the palace. We went all over the city and the surrounding area like this, me pulling the cart or with my mistress riding my shoulders, while my magically enhanced ponyboy body took the weight with ease. The client, I had no idea who she was, took a moment out of her day to inspect me.
"He's so lovely and fresh," she said. "How old?"
"Eighteen and a week, and my wife and I have had his age fixed there. We wanted a nice tender colt."
"The hot-pink harness really suits him, and I love the matching hair - I always like it when ponyboys get a proper mane rather keeping the human one. Did you make any other changes?"
"Quite a few - it's Shami who did the actual transformation magic, you know, she just finished her training. We really wanted him to be absolutely perfect. We did the ears, then the tweaks to his face, then we took away his hands and converted his feet too, gave him a tail, enhanced all his muscles, got rid of every last body hair and gave him his pony voice."
"Did you shrink the cock, or ...?"
"Yes, we wanted a cute little thing and it was too big for our ponygirl's very small pussy anyway. I always think smaller ones suit the skinny boys better."
"So you still have Head Girl, then?"
"Oh of course, she's ours for life. We're going to courier with them both, so we can expand the business. I've got more deliveries to make, sorry - I'd better go. Send me a thought message if you need anything picking up."
"Sure thing, Rashida. Oh look how his tail swishes - he must love to run!"
"He'd better. Pull out now, Pretty in Pink. Good ponynoy!"
I neighed with real enthusiasm. Mistress Rashida cracked her whip in the air behind me anyway, as was her right as my owner, just so I knew not to disobey. Lifting my knees high with every step and letting my cock sway and bounce, I used my enhanced strength to draw the cart away from the offices and into the street, where I soon had the little vehicle rumbling along at high speed.
With blinders on, I could only see directly in front of me, and as my hooved legs ate up the distance to our next delivery, I let my mind wander over my life before and after I'd cast the spell that I'd found tucked away in an old book in the library of my elite school. It called out to me somehow, drawing me to it and making sure I would keep its secret, until I cast it and found myself whisked through a portal into what I thought would be the world of my dreams.
Such dreams I'd always had of serving the most dominant of women, and indeed, that was what I now found myself doing. I had landed, naked as the spell required, on soft hay that lined the floor of a locked cell in the dungeons of this elven queendom. Elven guards - women, like all elves - had come in a while later after hearing my tentative calls, and had quickly shackled and collared me, then dragged me through the dungeons into a large holding area where I was chained up to the wall alongside a dozen other naked eighteen-year-old boys and girls who had cast the same spell all across the world. The elves magicked my voice away, muting me, and that was the last time I spoke like a human.
My owners bought me the next day from a government-run slave market, and they took me back to their small home in the centre of the city on their cart, which was pulled by a slim, small-breasted and fair-skinned blonde ponygirl wearing a cherry-red harness that both held her and put her utterly on display. On the cart, I looked over my new mistresses and found them to be immensely to my liking, not that that really mattered to them.
Mistress Rashida and Mistress Shami were, I gathered over the next week, fairly new to the elven queendom, having been changed from humans only a few years before when the elves had sensed their dominant minds in danger as they faced a civil war in their country. Where my skin was pale and a little transparent, theirs was dark and strong. Mistress Rashida wore her black hair long, in braids that fell down her back, while Mistress Shami kept hers close-cropped. They dressed in classic equestrian outfits or long green or white dresses (when not working) and they were pure, dominant divinities in my eyes.
I was jolted from my reverie when Mistress Rashida drew me to a stop outside our next destination, where I waited in the street while she went inside with a parcel to make sure the delivery reached the right hands. An older elf approached me and stroked my face as I stood stock still, not daring to resist at all, for I knew that the magic cast over me by the elves would have wracked my naked, harnessed body with pain if I even thought of violence or escape. I rarely did - after all, I had wanted to be a slave.
The older elf ran her hands all over me, picking out my enhanced muscles and lingering on my tight bottom, then violating me with a finger while I stamped and snorted. My cock grew erect, and I looked down at it and blushed - it was a lot thinner and shorter than when my owners had bought me, but they were right that it fit better inside Head Girl, their ponygirl, that way. The little blonde certainly seemed to enjoy it, almost as much as she did having my tongue on her clit or her arse.
"What do you think of him?" said my mistress as she came back out into the street and hopped up onto the cart.
"He's a fine animal, very sweet-natured and well-behaved. I love the bells on his nipples, by the way."
"Thanks! My wife thought those up, she wanted him to tinkle charmingly as he ran."
"I love the lipstick too - hot pink gloss looks so good on him."
"We thought so - it's the permanent kind, doesn't come off unless we magic it off."
"Been an elf long?"
"A few years - he's only my second slave."
"Well done for breaking him so quickly!"
"Thanks! See you. Up and away, Pretty in Pink! More deliveries to make back in the city, ponyboy!"
I neighed my assent and the older elf stepped out of my way. My cock remained erect as I ran, and for some reason in that moment I remembered the feeling of it being depilated then shrunk by Mistress Shami's elven magic, which only made me harder as I pulled the cart and my other owner along. Mistress Rashida, obviously reading my thoughts, laughed and called me a good boy, and I got goosebumps at the words just like I always did.
My eyebrows and my braided hot-pink mane were the only hairs I had left anywhere on my body, and their removal had made me feel like my manhood was being stripped away and replaced with something softer and prettier, to be displayed for the pleasure of others. Just as my slave body should be. I kept on lifting my knees high as I ran for my mistress, taking her closer and closer to the next drop-off point, which she would guide me to with word and whip.
It hit me then that the older elf had described me as broken quickly - so quickly. There had been magic involved, for certain. I knew, on the marrow-deep level of complete certainty, that I was a ponyboy and not a human, and I knew that I was something, not someone, something owned and cared for and free only to enjoy the fruits of being owned. I could barely imagine not being the property of Mistresses Rashida and Shami, and the attempt made me queasy and caused me to stumble, which brought a slash of the whip. I thanked my mistress in my mind, for the discipline that I needed, as a little blood seeped from the cut left by her strike.
