Man into Female Horse Transformation Story

I enjoyed the presentation of the horses. I didn’t expect to see so many breeds of horses. I didn’t even expect to come here in the first place either. Nonetheless since the happening was not that far from my house I thought why not.

I’m about to leave the presentation tent, but suddenly one of the announcers comes up to me. I talked to him before the presentation and told him that I wasn’t a rider or anything like that, I just wanted to see some purebred steeds. The man is very smug and looks like a bauble seller at the moment. “Hey! You’re one of the last people to leave. I’m glad you seemingly enjoyed the show so to say!” He politely concludes. “Yeah, I actually did. I liked how you didn’t make it a plain presentation of each horse, but included some tricks and other rad activities. I appreciate those kind of happenings exactly because of that, because people are trying to make them interesting and do what they love in them – Work with horses in this case.” I reply to him as politely as possible and I mean what I say. “Glad to hear. Say, would you… Would you like to see your favourite horse in person? You saw them from the audience seat, but I can show you the horse up close if there’s one you liked the most!” He explains. “I’m not entirely sure if that’s a good-“ I tried to culturally deny, but I was interrupted by the brightly dressed up man. “Oh please. I would love to help your passion for the horses grow. If you wouldn’t have come here you wouldn’t even know that you like the horses. It won’t be a long “meeting”. You’d get to know the most beautiful horse up closeee…” He allures me. It’s starting to get weird, but the pressure is too much. “You’re right. I don’t know when I’d have the next opportunity to see a purebred up close. Can’t let it go to waste now. I’d love to see that black fri-esian one. Lead the way please!” I give up on resisting. The man smiles at me and opens up the tent for us to head out.

He leads me to a smaller tent nearby, but in a more secluded area. Well this entire event was organised in the wilderness on purpose, to feel more natural amongst other things. “So… What will I be able to do with the horse? Brush it or…?” I ask unsurely. Now that I started thinking about it I really have no idea what’s in store for me in that tent. The announcer opens up the tent and gestures for me to enter first. “What will you do with h- it…?” He says in a weird tone. I get inside the tent and wait for the man to come after me, but he doesn’t. “I have a better question – What will he do to you? Hahah!” The man says in a creepy tone. “The hell? Hey, what the fuck was that supposed to mean?!” I stammer in shock and fear. I see as the man rapidly closes the tent and I hear a sound of metal clacking. I rush towards what used to be an opening in the tent. I try to slide it open, but it’s not just closed – It’s locked. “Oh God… Why did you lock me in here?!” I cry out in panic. “Man, I love this business. You’ll be my golden goose once he’ll be done with you.“ The man says as I hear him walk away.

“Maybe I can… Fuck!” I exclaim as I try to tear open the door, but fail to do so as it proves to be made out of too resilient material. I’m done for… - I think to myself as I slide down onto the floor from helplessness. “Wait… He said something about… A horse doing something to me…?! Why would-“ My audible thoughts were interrupted as I suddenly heard the iconic clopping sounds of a horse – It was stuck in this tent with me, or was it the other way around. I’m on all fours on edge, but I slowly turn my head back. From the shadowy part of the dimly lit tent a huge equine silhouette steps out. As I see more of it’s contours I realise it’s the horse I liked the most. I don’t know why, but there’s something off about this horse. I eye it warily and then I notice it… It’s clearly a male, a huge stallion, but that’s not what worries me. It slowly walks towards me snorting and with a bobbing thick as a can erection. I start trembling. Did they do something to him? I can’t believe he’s erect at the sight of me. I crawl away from the horse in panic and try to rise the base of the tent to get out.

The stallion notices and hits me hard with his head. I roll to the centre of the tent until I find myself on all fours again. I try to get up but the horse smacks me again and I land on all fours in disbelief. The horse seemingly moves towards me and I blink in panic. “I beg you don’t do this to me. S-Stay away!” I mutter and readjust my belt to protect me from the stallion. I’m surprised to realise that the horse doesn’t move into the dangerous position, but steps away from an opening in the tent. A flash of shiny metal and then I feel a sudden painful jab in my leg. I see the tent closing again and I glance down at my right thigh. A sharp injection dart is sticking out. I tilt my head devastated and pull the thing out of my body.

My heart starts beating faster and my vision becomes woozy. I already feel the effects of whatever was in the dart start working on my body. I glance back at the stallion and he observes me, but does nothing more, for now… I feel like I’m in a fever dream. How did I end up in my current situation – I wonder frightened as I look for a way out. I try to focus, but it’s increasingly harder as my body starts to tense up and sweat intensively. My muscles ache and feel like they’re swelling. To my horror I realise that is the case as I stare at my bare lower arms. My skin is getting tauter as my muscles swell beneath it. “What in the… What’s happening to m-agh!” I groan in discomfort as I feel something snap in my arms. My eyes widen as I realise my arms slowly and painfully stretch longer. I lose the ability to rotate them as the bones in them reshape. “Th-This can’t be happening to me…” I protest, panting hard while at it. I stare as my human body hair falls off my morphing arms and an itching sensation appears on them and my entire body. I scratch my arms and notice short black fuzz growing on them. “Oh God, it looks almost l-like fur! It can’t be…” I protest and compare my growing glossy hair with the fur of the stallion next to me. As it grows I realise that it does look exactly like the stallion’s fur.

My muscles hurt like hell, especially as they swell larger along with the rest of my flesh. My clothes get painfully tight on my body and I feel like I’m going to suffocate if I won’t take my shirt off at least. I turn in the stallion’s direction. “I h-have my eye on you, don’t you dare…” I stammer as I take off my shirt, which is hard because my hands feel strangely stiff. The pain in my legs intensify and I decide to undress completely feeling how my entire body painfully shifts. It takes me a surprisingly long while to completely undress, because my limbs don’t bend like they should. Finally I’m completely naked, except no – I examine my body and realise it’s completely covered in short black fur that becomes denser. I can see and feel that my skin slowly thickens into hide and changes hue underneath my fur as well. I feel a need to straighten all my limbs as the muscles in them grow bigger and harder. I can’t believe what I see, but my arms are practically the length of my legs by now and they all slowly grow longer as they gain additional muscles. With the black fur and their changing shapes I hate to admit they look similar to those of a horse.

I gasp suddenly as I feel my torso shifting. “Ghck… Ah! Sthoooop it…!” I choke as my ribcage starts to painfully barrel out and grow larger, changing the shape of my entire upper torso in the process. My lungs and all the other organs readjust in my expanding chest and I finally feel like I can breathe again, although in a significantly different way. My shoulder blades crack violently and I feel like they’re solidifying my arms in a four legged stance – I can’t move them like I used to no matter how I try. “No, wait! Fuck, my hands…!” I grunt as I feel my stiff hands contort. All of my fingers slowly and painfully fuse together to form a more compact and sturdy formation. My nails swell larger, blacken and envelop my changing hands from underneath. I stomp my fore legs and I realise they’re practically indistinguishable from those of a horse. “Fuck sake…!” I curse in horror at the realisation that I just lost my hands.

My continuously changing torso swells larger and becomes barrel shaped in the process. I notice that I’m slowly getting almost the size of the stallion next to me who carefully watches my grotesque transformation. I arch my back for a second, just to straighten it as it starts painfully thickening. I hear popping and feel how my spine get’s more pronounced on my increasingly muscular back locking me forever into quadrupedal stance. I close my eyes from the discomfort as I feel my organs swell larger and change shapes. My closed eyes undergo their own transformation as they become darker. My pupils ache and I realise what’s happening. I open my eyes and see as my vision widens, just like my pupils. I see the world from a wider perspective now quite literally with my eyes being distinctly equine. I feel hopeless as more changes invade my poor body. My crack and start widening to better cooperate with my body. My pelvis rearranges and my legs get locked in their quadrupedal position. I feel my entire legs, but mostly their upper parts swell with hard muscles. I glance down at my feet and realise they don’t exist anymore. My hind legs stay on my tip-toes which already lost their toes to form one big hoof on each leg. What’s left of my toenails changes colour to black, forms my hooves and solidifies considerably. I notice that the fur above my four hooves is longer and I’d find it elegant if it wouldn’t be my own!

Finally I feel like my torso settles down with its changes. I feel it swell broader and bigger with a few uncomfortable growth spurts. Then I notice something bizarre. I feel my ass grow huge in comparison to what it used to be. I gulp as I feel my butthole pucker out and push out into a more exposed position, more fit for a quadrupedal animal. I cringe at the feelings, but then I realise something weird. My chest is itching, I feel like something on it is tugged and pulled towards my lower body. My neck starts cracking as it broadens and lengthens, which allows me to crane it down and inspect the changes. I look beneath my body and I shudder as I see how horse-like it appears. “W-What a-are… Is that… Oh Lord, nononono-nhgnnn…!” I start freaking out as I realise those two points migrating down to nestle between my muscular legs were my nipples. They blacken and sag down a bit as fat builds underneath them. Slowly an udder with two visible teats forms. I feel their weight underneath me, but if they’re between my legs than… “Ahn! Fuck, m-my cock. God, I feel i-it moving-ghn… Ahhhhhhn!” I moan in discomfort as my genitals are hauled closer towards my black pucker. I stay motionless as I realise what’s really happening to me – It all makes sense now, I’m becoming a mare!

My body has grown huge at this point, my silhouette is the size of the stallion roaming around me. Albeit my genitals didn’t change yet, they haven’t even grown – Now I realise why… “Mhn… Fhr-Fhnhuuuuck… Gheeeeeelph mnheighhhh…!” I cry out in despair as I realise my voice abandons me as my neck slowly finishes changing. I stomp my hooves as hard as I can to protest, since I realise I can’t do anything more in my current helpless state. I feel my cock bizarrely dangle and get erect right underneath my anus. My balls suddenly squeeze in and make me neigh at the top of my lungs as they flush me out of all my seed. I feel my cock twitch a few times between my steel-hard buttocks. Cold cum drips down my muscular ass and I get beet red in shame.

Sadly it was just the beginning. Even though my distant orgasm has ended ridding me of all my male seed I still feel my cock twitch. It pulsates and with every movement it shrinks. I feel it slapping against my hard buttocks as it slowly gets unbelievably small. Just then my empty balls are starting to get pulled inwards. “Ngheeeeeigh-khn-hnoo...” I whinny as I feel my balls painfully slide past my hips and deeper into me as they churn and disfigure, slowly turning into ovaries. My cock almost completely disappears leaving a tiny hole beneath my scrotum. Oddly I feel my leftover scrotum get very sensitive. I move my legs and enjoy the feelings of my muscular upper legs stimulating my sensitive ballsack. Unbeknown to me my scrotum darkens in shade and puffs out. It becomes leathery in texture and distinct lips start forming – Only now I realise what the feelings signify. I open my mouth, but I’m unable to scream as I feel my puffy black scrotum suddenly split open down the middle forming an equine vulva. I can’t move – The feelings paralyse me. I feel my vulva swelling larger and I feel like it’s upper skin fuses with my lower butthole. The other hole left after my cock slides in between my swollen vulva and shifts into a clitoris. I shake my head and start turning around in many ways to see what the hell has happened to my genitals, but I can’t bend myself that way yet. I can’t even if I’d want to as my legs buckle under the new blissful sensations inside my forming cunt. I feel an invisible force burrow a hole in between my hips. I shudder as I feel my new big womb forming inside me and at first it feels like an air bubble inside of me, it’s all so new and overwhelming. “I- Iaaaaaigh… Hmrhhht!” I whinny and snort when I try to spell out a revelation about my new gender.

I feel my human hair fall out of my scalp. Immediately my black mane forms on my neck and head, signalling the changes to my head are next. I can’t even scream for help as I feel a massive headache wreck over the entirety of my skull as it begins to remold and grow larger. Suddenly I feel my ears get warmer without the need to touch them, they start to lose their complex human shape and start to stretch longer as they thin down. I can feel them turning into rather pointy forms as they stretch and grow short black fur all over. I accidentally force my changed ears to twitch in an equine manner. Even my face won’t be spared from the changes, I realise as I stare at my nose which seems to melt in my sight. My nose widens and the nostrils flare out. My gums hurt and throb as something starts happening to my teeth. I panic as something suddenly lands on my lengthening tongue. I immediately spit it out and realise it’s my human molar. I feel more of my teeth loosening and falling out of my shifting gums. I spit them all out in disgust. They land on the ground beneath my fore legs along with blood and saliva, I instantly look away from the sight.

My head grew larger to fit my neck and now it starts losing its human shape. I start to snort and neigh in panic as I feel immense pain in my cranium, cheekbones and jaws. My cheekbones start to swell out and make me lose even more contours of my human face. My forehead slowly starts to lower. My head starts to painfully slope down at the top, my cranium shrinks and squeezes my brain into a smaller shape. My jaws start to grow larger and push outwards. This completely rearranges the remains of my face. My changed eyes are forced to drift apart. I notice my eyebrows completely disappear while my eyelashes grow longer. I stare cross eyed as my growing nose starts to move away from the rest of my face. My mouth is stretched wider and my limps become plumper as my jaws march forward. I feel an alien weight being added onto my head as my huge snout forms. Slowly it finally ceases to grow longer and I can sigh with relief and enjoy the rest of the tormenting changes. My tongue catches on with my changed maw and grows appropriately longer. My reconfigured gums throb once again, albeit in weird places. I feel them slowly and painfully get pierced by about 40 tough and big equine teeth. It’s like growing my permanent teeth again, except they all grow out right now intensifying my suffering, not to mention they’re horse teeth and are more massive than they’re human counterparts. Wide, but relatively thin incisors pierce my front maw and grow out. Then aches deeper in my maw signalise the growth of my distinct canine teeth along with molars and premolars. Slowly, but surely all my teeth writhe out of my gums and fill my gaping horse maw. I pant through my wide nostrils and blink unsurely as the last changes wash over my head. Lastly my black, glossy fur covers it whole and I realise there’s only one last change to finish my torment.

I step from one hind leg to another as way above them my spine starts throbbing and pushing at the flesh. Slowly a visible tail nub forms and starts to push out as muscles and nerves form around it. My tail starts to sway because of my unfamiliarity to it. I feel like the movement helps it grow though and so I continue and feel it slowly lengthen into its final shape. Then it starts to itch and very long, black horse hair grow out.

At last the changes are finished – I think to myself and am about to storm out of this tent. Except that as I timidly start moving on all fours I hit something warm and hard with my new nose. It’s the black stallion, I imagine we must look very similar by now, except… I’m a mare… I tremble as the stallion starts huffing and rearing up, flashing his erection at me in the process. I really want to get out of here, but I feel like I can’t. Something deep in my mind tells me that I can’t just ignore the stallion’s behaviour. I close my eyes as I shyly lift up my tail and move it to the side. Exposing my swollen, dark and leathery cunt to the cold air and the stallion’s disposal.

Before I realise that the stallion is gone from my sight I feel a gentle tug at my teat. I crane my neck down slowly, enjoying the feelings. I notice the stallion is licking my teats with his slobbery and warm tongue. I feel a heat rising in my cunt making it puff out more as it swells with blood. Unbeknown to me a few drops of my juices ooze out of it and its enough to catch the stallion’s attention. He smells the aroma and is lead by it towards my fresh entrance. I realise he stopped licking my udder, just to move behind me.

I glance back and I notice his fat erect cock prepare to enter me. The male jumps onto me and my legs buckle under the weight of his muscular body. I feel his flared tip brush against my big and hard ass until it hits the jackpot. I feel his hot and hard mushroom against my twitching lips. He doesn’t wait any longer and slowly starts to push his shaft inside me. I whinny and throw my head up displaying my mane as I feel my big pussy walls hug his cock tight. I’m astounded by the length of his cock, now feeling it entirely enter and fill my pussy. I shudder and don’t move waiting for the stallion to make his next move. I feel my cunt start to heat up and self-lubricate as the male starts grinding his hard cock inside me. He thrusts his hips in and out making me see the stars in the process. I unwillingly lower my ass from the overwhelming ecstasy. Until suddenly after multiple thrusts his cock starts to spasm inside me and I feel like he’s going to tear my cunt apart. His cock starts to spurt out huge loads of hot cum inside me, stuffing me entirely. It’s too much for me and I whinny at the top of my lungs and jump with my upper body as I come. My walls constrict his cock and clasp around it many times as I feel like my orgasm has no end and continuously hits me with more sensations. Suddenly the male pulls out and my entrance winks oozing out litres of cum as my orgasm slowly ends.

I collapse onto my side defeated by my own changed body and its new sensitive weaknesses. The male snorts in my direction contently and disappears from my sight as I try to catch my breath. I feel like I’m passing out from the shock of the transformation and the most intensive sex in my entire life. Before I do I hear “She’ll be a good broodmare. Pack her up-“ So this is my new life now.
