I lay on the straw covered floor of my stable, the frosty wind whistling outside making me grateful for my heating home, my owner takes great care of me, he could just leave me to deal with the cold like a wild pony would but instead he heats my home for me. The wood door rattles from the wind as I try to sleep, the lock keeping me safe from the elements and any predators who might attack a helpless creature like myself, voiceless and armless, I have little ways of fighting back if some wild animal ever tries to come after me. Not that my owner would ever let that happen, he takes such go care of me, homes me, feeds me, washes me, gives me work and purpose, and I return I do my best to serve him, be it serving as his personal cart horse or ploughing the fields or transporting heavy cargo, I do my absolute best to show him that I'm worthy to be his pony and that I'm as valuable as he treats me. 

I close my eyes in the dark, resting on the thick pile of straw that is my bed, trying to ignore the hollowing wind outside as I drift off to sleep, ready for my next day of hard labour. 

I awake to the familiar crushing feeling in my crotch, as my cock strains painfully against the metal of its chastity cage, while my bladder groans with pressure. I rise as quickly as I can in my heavy hooved boots, the only item of clothing I am allowed to wear, ones I've long learnt to balance in as they force my feet downwards, my legs needing them to stand these days, my feet unable to go flat, always at a steep angle when taken out for cleaning, requiring the hooves to balance my weight. With little control over my bladder I quickly move away from my sleeping area just in time as I begin to piss uncontrollably onto the floor near where I sleep, my piss soaking into the straw below as I spray the ground and my legs, my mind not caring about it or being bothered about peeing onto the ground, I'm just a pony, I go anywhere at anytime, I don't care who sees me, why should I. 

Feeling my stomach rumble I squat slightly and quickly hear the thud of my shit hitting the ground, the familiar smell rising up into the air and mixing with the other smells of my barn, the flies quickly swarming the fresh waste, coming out of hiding from yesterday's, not that I mind, I don't even notice them as they crawl over my body or buzz around me,  they're just a fact of life for a pony. 

Moving away I sleepily, I reach my water trough and lower my head down to the dirty water, one with bits of straw and mud floating in it, plus the odd fly, but I'm not fussy, I need a drink and this is all I get, I've seen the farm dog drink worse from muddy puddles, I'm just grateful to have any water. 

Finishing I impatiently pace around my stable, wanting to get to work and burn off my energy, hoping that I'll be let out soon, to be of use, to be active, to do something, my mind only thinking of my frustrated morning wood and how much I want to be let out, to run in the field, to pull my owner's cart, to plough the fields, my mind having long forgotten any of the human activities I'd used to fill my time with, now my only desire is to burn off the energy I have the only way I know how and to be of use to my owner and contribute the only way that I can. I turn to the door as I hear the heavy barn door open beyond my stable door and I stomp my hoof slightly in excitement. I smile as the top half of my door is opened and immediately trot up to my owner, of course making sure that my knees go high with every step as I was trained. I lean my head out and enjoy the feeling of my owner stroking it, I love his affectionate touch.

"Good morning pony, you ready to get to work?" I of course can't respond verbally but I stomp my foot a few times to show that I want out. I feel a few more strokes, this time on my shoulder as my owner smiles. 

"Good boy, I knew you would. But first we should get you fed and saddled." I step back slightly as the lower half of my door is unlocked and opened, allowing my owner to enter, not once thinking of escaping as he leaves the door open, although as he does I see his dog walk up and look inside, like me his body was modified for the role, his fingers removed to make useless paws and his feet taken to keep him on all fours, unlike me though who has to wear a chastity cage and live with endless frustration and denial and burn off the energy it gives me, the mutt was neutered and doesn't suffer in that way, which makes me slightly jealous as I wonder what that would be like but it would mean that I have less energy, however it probably would have made my training easier, the dog having no whip marks showing that he must have been less resistant than I was. 

My thoughts disappear as I hear the sound of my food pour into my feeding trough, one stained and marked with dried pieces of food. My stomach growls at me, prompting me to walk over and without thinking lower my head down to the oaty slop and begin to eat my meal down hungrily, the mixture of oats, vegetables and many drugs and vitamins keeps me strong, fit and healthy. As I eat I feel a damp wipe run over my ass, cleaning me from my earlier actions, my owner making sure that I don't catch anything. 

Feeling full and ready to work I stand still, not moving or resisting as my owner saddles me, placing my leather harness onto me, the tight straps digging into my flesh as he makes sure that I am secure. The vision to my sides disappear as my headpiece is put in place, the large colourful feather on top adding even more height on top of my hooves. Lastly I open my mouth as the bit gag is put between my teeth and the reins are attached, feeling the tug I obediently follow, my body immediately feeling the difference in temperature as I step through my stable door, my hooves loudly hitting the hard concrete beneath me, as my body begins to shiver as I get used to the freezing cold weather, the weather that I'll be in all day, part of me unable to prevent me from feeling slightly jealous of my human owner and his many layers of clothing and of the dog, who although naked like me can at least curl up against our owners body for warmth. 

Despite my shivering my strong muscular legs remain steady as I stand still as the icy wind blows over me, while my owner attaches me to the cart, its weight moving as he and the dog climb onto it, sitting at the front, my reins held firmly. Feeling the sting of the whip against my ass cheek, one marked with my owners brand, I begin to move forward, pulling the heavy cart behind me, slowly picking up speed as we leave the barn and begin up the dirt paths, turning to the tugs of my reins, guiding me and telling me when to turn, fully trusting my owner to guide me as I can't see anything to my side. 

I slow and come to a stop as we reach another barn, one housing the cows, both natural and hucow, the women, and some men, modified and mute, their food mixed with drugs to make them produce huge quantities of milk, requiring milking several times a day. From what I've seen of them through the doors of the barn they seem to only be able to think of having their swollen breasts emptied, their eyes seemingly looking desperate for relief from what must be painful pressure considering the unnatural size and looking so pleased once the milking begins, the only other thought they seem to think is of eating and being bred, their heads always buried in their troughs and their pussies and cocks always showing how horny they are. I stand, breathing hard in the cold, my body slowly getting used to the freezing weather, my face growing numb and my nipples hardening, my swollen balls shrinking as much as they can, prevented from retreating inside me by the metal ring behind them, the skin growing uncomfortably tight around them. I stomp my feet as I wait, unable to go anywhere as I'm anchored to the cart. 

I happily begin to pull the cart, not needing additional whippings to get up to speed as we move to the next location, happy to finally be moving and to try to raise my body temperature by going as fast as I can, although still being careful of any possible ice on the ground. 

Breathing hard I come to a stop, part of me wishing I could just keep going, finally getting to a comfortable temperature, now my body quickly cools as I stand patiently waiting by the pigs sty, like with the cows there is a mixture of natural and human, not that they seem to notice, as even now two unashamedly enjoy each others company in full view, the natural pigs resting on top of the large female, her limbs modified like the dogs, buried deep in the filthy mud as she joyfully squeals. The others happily bury their heads in the slop poured into their trough, one far less appealing than what I'm feed, made up of fats and leftovers, none of them put off from the horrid smell of their sty or their own filthy bodies. 

"One more job to do." I feel a mixture of sadness and joy at the words, part of me happy to be able to get out of the cold but also sad to only be out for a short while, still having energy to burn off. I move quickly as I feel the whip once more, racing off into the freezing winds, happy to be moving once again, especially away from the pig sty. 

I come to a stop outside the old flint house that my owner lives in, I vaguely remember what it looks like from my first day here, when I signed all the paperwork, back when I had arms. I don't remember much, mainly just being really excited to finally be living out my dream fantasy, only later learning the harsh and exhausting truth, my owner making sure I never stop no matter how tired I got, his whip hitting me over and over again until I built up my stamina, or as punishment for disobedience as he guided me on how to be a good pony, never giving up on me, always believing in me that I could become a great pony, which I'm thankful for and proud to be today. 

I watch as my owner fills the cart with various colourfully wrapped boxes, I have no idea what they're for, normally I don't carry things like that though, I normally carry farm equipment or milk or straw and hey or animal food, not these. Although what they are doesn't matter, it's not for me to know, all that I need to know is where I'm taking them. I feel my owner climb back on the cart, this time without the dog, I'm guessing he was left inside, not that I'm bothered by it as I move forward once more, quickly trotting down the dirt road, stopping by my owners car. As I wait watching him unload the cart and put the items into his car I feel a warm liquid splash against my legs as I unconsciously piss onto the frosty ground, my owner like me not caring, that's just what animals like me do. 

"Right then, that's all the jobs done for the day." I lower my head slightly to show my sadness. 

"It seems a bit early to get you back indoors, so why not go for a quick run." I smile behind my gag as the whip strikes my ass once more and with the lighter cart I begin quickly making my way up the path to the open field, picking up speed as my owner guides me around the large open space, my body quickly warming as I enjoy the flat open area allowing me to get to full speed. 

I breath hard as I slowly trot into the barn, my leg muscles burning amd my back aching after the days work and my run. I stand exhaustedly while I'm unhooked from the cart and my harness is removed. I happily follow my owner as I'm led by the reins back inside my warm barn, my reins hooked in place to the wall, leaving me leashes in place to rest on my exhausted legs, while my owner leaves. 

I hear him return with a bucket and feel the pleasant warm cloth as it runs over my cold and sweaty body, washing away the days dirt and warming me up. My owner cleans me most days, I appreciate how much he cares for me and looks after me, I like the feeling of being clean, not like the pigs in the sty who roll around in the muck. 

"There we go all nice and clean." I feel a gentle hand stroke me and I feel happy and content as they dry me off with a towel. I feel his hands caress my body and my cock twitches in its cage, there is one more thing my owner can do for me if they so choose. 

"You have been a good boy today, good boys get rewards don't they." I stomp my hoof slightly as my cock begins to strain with anticipation. I feel my owner move behind me and I stick out my ass invitingly for him. I silently gasp and moan into my bit as his cock enters my ass, my tired body shacking as he thrusts into me, my cock pushing painfully against the metal of its prison as he goes deeper and deeper. I begin to pull slightly on my reins as pleasure builds inside me, my heart beating fast, as I'm brought closer and closer to the edge, finally reaching it as I feel him cum into me, filling my insides with his warming cum, my legs shaking and back arching as I squat through my cage, my cum spraying the straw beneath me as I struggle to stand. 

Lost in a haze of bliss I stand unsteadily as my owner unhook my reins and removes my bit gag and headpiece, before gently lowering me down onto my bed of straw, my exhausted body quickly relaxing, my eyes closing as he lovingly strokes my body. 

"Merry Christmas pony." The lights go out and I quickly drift off to a well earned deep sleep as I'm locked safely away in my warm home.
