I press my head into my hands, letting out a deep sigh. After I give myself a few minutes in my car, I slowly get out, grabbing the meal I brought home, before heading into my apartment. As I slowly eat the take-out, a salt and pepper chicken meal, I realise that I need a change. I don’t know how many more late nights I can do, how many more take-outs I can survive in. No matter how good the chicken is, or how crispy and fluffy the fries are. I need something different, something outside of New York city.

The next morning is spent booking the following week off from work. And asking an old friend I know if I could come to his farm for a day or two, maybe help out with some lighter stuff. I just know I need to get away for some amount of time. Luckily he’s more than happy to have me over for a day, apparently needing some help. We set the day, and I try my best not to overthink the next few days.

The smell of the countryside fills my car as I get closer to Tom’s farm. Even with just this, it feels as though my stresses are starting to fade away. Getting to Tom’s farm, I have to get out to open the front gate, before driving into his farm. Parking in front of his house, I knock on his front door, waiting for it to open. Once it does, I’m met by a warm hug, Tom’s arms wrapped around my midsection.

“Shaun! You made it!” Tom says warmly, tightening his hug a little.

“Tom...” I sigh in response, hugging him back. “Thank you for helping me out.”

“It’s alright, big guy. It’s no big deal, it’s a pleasure to help.”

“But it is a big deal, you’re really helping me out.”

Tom pulls back from the hug, keeping his hands on my sides. “You’d do it for me, I’m sure.”

I give him a nod.

“Well,” Tom continues. “I’ve made your room up for ya, already. So, if you want to drop your things off, then we can do a couple things around the farm.”

“Sure thing.”

I do as he says, moving my overnight bag to the bedroom, before heading back out meeting Tom back outside. He has me do some smaller things at first; sorting smaller seed bags, feeding the chickens, and so on. The final task he has me do is checking the stable, making sure that the horses have enough grain and the like. I do feel a little anxious about this, as I’ve always had a small admiration towards equine. But agree to do it, as I want to make sure that I repay Tom back as much as I can.

I head towards the stable, which is little more than a renovated barn, the smell of horse fills my nose, making me blush softly. Slowly entering the barn, the scent of horse strengthening tenfold, my body trembles a little as I smell it. And while a small part of me is put off by just how strong it smells, there’s something beneath it, something that draws me into the stable. Being drawn in deeper, I move past stall upon stall, until I find myself at one that seems to emanate the underlying sensation.

Inside the stall, there’s a mare near the back wall. She’s muzzle deep inside a wall mounted hay feeder. This means her backside is aimed almost directly at me, giving me a good view her rump. With a small blush, I look over to the main door, I take a moment to make sure no one is nearby. Turning back to the stall, I slowly enter, the mare’s ears perk up as I do so. Slowly closing the stall door behind me, I move closer to the mare.

“Hey there, girl.” I say to the horse, knowing she won’t understand me. As I get close to her, her tail perks up and waves to the side, giving me a good view of her mare-hood, only making me blush deeper. Taking a moment, I look up to the mare’s head, which is still deep inside the feeder. “I thought all the horses were brought out. What’s got you kept in?”

I let a hand move up to her backside, gulping slightly as I make contact with her large, plump rump. Her ass has got a good amount of muscle underneath her short fur, but with a good amount fat, for lack of a better term. Trying not to be too suspicious, even if no-one is looking, I slowly move up the mare’s body. Letting my hand roam the side of her back, my fingers trail every curve, book and cranny. She has such an amazing body, one I admire greatly. Licking my lips softly, my hand comes to her shoulder, my thumb rubbing against the bone softly.

But something takes my focus, making my head turn, coming within an inch of the mare’s snout, its blunt end almost against my face. Her nostrils flare, and breathes out a warm breath across my face. This makes me tremble as she moves her head forward a little, giving me a small kiss, which paralyzes me. It’s a quick action, one that makes me question my sanity, let alone whether or not it actually happened. She pulls back almost as quickly as she kissed me, her gaze focused on me. This continues for barely a moment, before she moves again. But this time, she aims for my shoulder.

I barely have time to cry out in shock, before I cry out in pained terror, her teeth sinking into my flesh. They pierce deep enough to grind up against the bone, shaking me to the very core. My hands go to her snout, trying to push her off of me. Despite this, she keeps herself firmly locked in my shoulder. My fingers dig into her maw, as I feel something enter my through her teeth. It feels as though my veins are being filled with something, invading my very bloodstream.

“Get the fuck off of me!” I cry out, tears flowing down my cheeks as I continue to struggle. “Please! I-I’m sorry!”

Time evades me as the horse keeps her jaws locked in my shoulder, making me tremble every time her teeth scrape my shoulder blade. The horse moves her tongue to the wound, giving it a long lick. But finally, after a torturous eternity, the horse pulls away, allowing me to fall to the floor, grabbing onto my wounded shoulder. I take a second to sob on the floor, feeling the equine’s saliva sink into the gashed skin. Getting to my feet shakily, I run out of the stall, before making my way out of the stable. The tears in my eyes making it incredibly hard to find my way away from the stable.

“Shaun?” Thomas asks, his footsteps come towards me, before stopping just in front of me.

As I continue forward, I push past him, crying out slightly as a jolt of pain shoots through my entire body. A coldness runs through me as I move forward, getting to my car after an eternity of searching. My free hand trembles as I search for my keys, taking a good minute for me to get them, getting them into the lock after another shaky minute. I manage to get the door open, falling sideways into the car before slamming the door closed.

I can’t think straight as I drive forward, trying my best to aim towards the entrance of the farm. As I get to the front gate, I expect to feel the rumble of hitting the wooden structure, but I screech out of the farm. The next few hours are a blur, and before I know it, I’m back at my apartment. Slamming my way through the front door, I fall to the floor, my world fading to black.

---

Waking up, I find myself still on the floor of my apartment. Slowly getting up off the ground, I look at my shoulder, finding it covered in dried blood. I have to do a double take, as I find a scarred over bite mark, rather than the open wound I had. It looks a few months old at least, and not the hours old it is. As I get to my feet, I feel pain shoot through my body, radiating from the scar.

Looking around, I find my front door still open, and I remember my car. I close my apartment door, before slowly heading back down to my car, finding its door still open, but my keys not in the lock. It takes me a moment to realise they’re in my hand, my fingers clenched tightly around them. I make sure that nothing is stolen, before closing and locking the door, before heading back to my apartment.

Once I’m back in my apartment, I sit down in my living room, resting my head into my hands, my breath drawing out in a deep huff. I try my best to process what just happened, my mind reeling as my body shivers and tremble. Minutes start to tick by, and nothing seems to make sense to me, no matter how much I try to think about it.

“What the fuck...?” I ask, digging my fingers into my skull. “What the ever loving fuck?!”

I slowly curl up into a ball on my couch, wrapping my hands around the back of my head, burying my head between my thighs. My voice is quiet as I try to reassure myself that this isn’t happening, that this is a bad dream, that the stresses of the last few weeks have just gotten to me. A part of me questions if I even made it to Tom’s farm.

Over the next few days, I try to put the event into the back of my mind, trying to forget it. Despite what happened, a part of me actually believes that it was some sort of fever dream, or hallucination. Maybe I spent the day rambling about doing farm work, horses and bite marks. I mean, what’s the chances I got bitten by a mare, before making it all the way back home without bleeding out, with barely a scar to prove what happened. Leaving my flat and car open to be robbed, only to have nothing stolen.

Opposed to it all happening, and somehow coming out the other side, seemingly unharmed. They say the simplest solution is usually the correct one. And outside of the bloody and torn shirt, and small scare on my shoulder, I have no real evidence of it happening. I mean, maybe I cut my shoulder while experiencing a mild psychosis? That would explain the scraps of evidence I have. And having thrown the short away, and my scars having had mostly healed over, it makes it a hell of lot easier to convince myself, that this is what actually happened.

---

After almost a week, I’m almost certain of the situation I told myself, even if it’s just to make myself feel better. Spending most of my time off inside my apartment, living off of online grocery orders and take out, while playing on my Switch for the most part. But, most of my time is spent on my couch, trying my best to come to terms with a momentary, stress induced psychosis. It’s on the very couch, where I feel a sudden pain shoot through my head, as if someone pressed an almost molten hot spear through my skull. I bring my hands to my head, heat radiating inside me, growing hotter and hotter. It feels like my blood is boiling inside my veins.

“No! Fuck! I’m burning up!” I cry out, trying to process whatever is happening to me. “Make it stop!”

Falling to my knees, my fingers dig into my head, grinding my flesh against my skull. I breathe heavier and deeper, curling over as pain shoots through my entire body. Rolling my head back, I cry out again, tears forming in my eyes, the heat still rising inside me. My body convulses forward a little, as I bring my hands away from my head, looking down at them, as I feel the veins underneath my skin shift and move, bulging out as blood floods them.

I clench my eyes shut as I feel my bones start to shift inside me, screaming out in pure pain. Trying my best to open my eyes, I can just about look down at my palms begin to elongate. The bones inside them extend out, stretching the skin. Another cry of pain escapes me, as I try to process the feeling of my skin distending and reforms. Rolling my head back for a moment, my body continues to convulse as I manage to bring my head back down, forcing myself to actively process what’s going on.

The bones in my fingers start to shift too, bringing all of my digits together, restricting their flexibility. All five of my fingers start to morph together, my nails conjoin as my skin fuses and my bones begin to bend. Sobbing softly, I can only watch as I feel a couple of my bones break inside my hands, forming new, separate ones. I cry out more as my fingers combine fully, my nails form together and bulk out, turning black as they form giant hooves.

My body convulses as my blood vessels bulge throughout my body, blood flooding through them. I can’t do anything as my heart beats like a drum in my chest as I crumple forward, my face grinding into the carpet. With my ass sticking out in the air, my mind reels as my muscles are taken control of, causing my whole body constrict into a ball.

“Oh g-god! I can’t take this!” I cry out as my whole body heats up even further, sweat pouring down my body. “Make it stop!”

Something shifts along my spine, feeling it almost... crawl under my skin, bulging out from inside me. More tears fall down my cheeks as my spinal cord bulges within my vertebrae, pressing out against my bare bones. This causes pain to course through my entire body, finally being able to slowly raise my head, going cross-eyed when my vertebrae begin to grow too. I’m barely able to open my mouth, trying to speak words, but only a deep groan escapes my lips.

My nostrils flare wide as I take in deep breaths, the scent of musk filling my nose. This makes me shiver as I look down at my body, barely able to do so as I watch my cock throb and shift beneath me. Despite the pain shooting through my entire being, lust still ebbs and flows through my length. I watch as the changes begin to effect my cock, making it grow outwards, getting thicker and longer, as the tip begins to become blunt. Every heartbeat forces more changes on my cock, my balls begin to grow in size too.

The scent grows deeper and stronger in my nostrils, numbing my mind as my genitals expand out, the skin darkening further and further. Biting my lip, I watch as my member changes more, unable to stop it. Before I know it, it becomes a thick, equine member, a pair of heavy, horse balls hanging just behind my cock. It’s a quick change, and by far the least painful, but even this makes my mind continue to reel.

With a deep groan, my vertebrae bulge out from my back, stretching my skin out as I slowly regain control of my muscles. Moving up a little, I move my left arm forward, finding my forearm has turned almost fully into a horse’s leg. Moving my right arm out, I find that the same has happened to this one too. My ribcage starts to bulge out too, my midsection pushes in every way, in length and girth, forcing my legs back as it grows more and more.

I fall fully onto the floor, only able to huff as I feel my body change and shift against my will. Every bit of my energy leaves me, only able to endure as the changes moves down to my legs. My toes start to crack and shift underneath my flesh. While I’m unable to bring myself to look down, I can feel every change that’s happening to me. My toes start to merge together, just like my fingers had, my nails conjoining before thickening, forming a large hoof on either foot. My ankles stretch back, pushing upwards until they form equine legs.

Once my legs match my arms, my forearms and legs start to bulk out, muscles shifting and forming underneath my skin. With each heartbeat, new blood vessels shift underneath my flesh. Causing my arms and legs to seize up, more and more muscles bulk out, even more pain shooting up through me.

I cry out as dark brown fur starts to push out from just above my hooves, every single hair feeling as thought it’s piercing my skin. My eyes roll back into my skull, unable to properly process what is happening to me. As my forelegs stop their change, the fur continues to grow up my limbs, getting to my oversized midsection, before continuing over my body. I start to slowly stand up in all fours, sweat pouring down my body, drenching my skin as I barely manage to stabilise myself on my hooves.

Everything feels heightened, as if every little movement and shift inside me has doubled in strength. Leaving me unable to do anything as my ass starts to grow outwards, plumping up as my hole starts to do the same. More tears form in my eyes as my rump pushes outwards, weight gaining more and more with every second that passes. My ring grows outwards, plumping up, matching an almost doughnut shape.

Huffing my breaths out between cries of pain, my head rolls up as I hear a knock at the front door. I let out a groan as instincts force me to get to my hooves, slowly looking over to the hallway to the front door. My overwhelmed brain is unable to process what I should do in this situation, feeling as though I should know what to do, but the information is out of reach. As another series of knocks come to my ears, I feel the changes start to move up my neck, causing me to groan out again. This time, it’s less painful, and more pleasurable.

I move myself forward towards the front door, as if I know what to do when I get to the noise. But I trip over the couch, falling over it before finding myself on the floor once again, the sharp sound of the sofa crashing back, making me startle before trying to get to my hooves once more. I let out a loud neigh as I roll onto my front, quickly getting onto my hooves. Once I stand up, I buck my back legs out, kicking against a nearby bookcase, knocking it over, the books flying onto the floor. I let out another loud neigh, kicking out into the air again,, stomping the ground heavily.

“Shaun?! Are you there?” The sound of a feminine voice comes from the other side of the door. “Are you okay?”

I perk my head towards the door, slowly moving myself closer to it. My legs shake slightly with every step I take, feeling my neck bulk outwards as it continues to change. When I try to push myself through the door frame of the living room, I’m blocked by the bulk of my midsection, stopping me in my tracks. Another series of knocks sound from the front door, making me raise my head once more. Before I can do anything, I hear the jingle of something metal, before the front door jolts open. As it opens, the face of a woman perks around the door, and for a moment, I don’t recognise her. But then, as she focuses on me, I realise that it’s my sister, Charlotte.

“Oh fuck...” She half whispers, her eyes going wide. “What the fuck...?”

I open my mouth, trying to say something, but only meaningless noise comes out. Trying again, this time I have a little more luck. “H-h-help... me-e...”

She takes a moment, looking me over for a moment. “What the fuck...?”

I shiver as I press up against the door, feeling my entire body shift and squirm. The changes move up my neck further, getting to just behind my cheekbones. This seems to take Charlotte by surprise, her eyes somehow going wider for a moment. After a few seconds of looking me over, she looks either side of the outside of my apartment, before coming inside and closing the door behind her.

“What the fuck... Shaun?” Charlotte asks, taking a moment to properly process the situation. “That is you, isn’t it Shaun?”

I take a moment, trying to figure out how to answer her. After a few seconds, I slowly nod.

“What the fuck...?”

I look at her, before looking side to side, then back at her as she moves up a little closer to me.

“What do you expect me to say? I mean... fuck! You’re a horse! A part horse! I mean... what’s up with the human face?”

After a few moments, I only look at her, raising an eyebrow.

“What? Can’t speak? You just spoke!”

“Ba-are...” I try to say, my tongue feeling thick and numb in my mouth. “-ly...”

“Fuck...” Charlotte says, putting her head into her hands, taking a couple seconds before pulling her head free. “How the fuck did this even happen?”

Again, I’m not quite sure how to respond to her.

“Oh for fuck’s sake! Do I need to keep it to ‘yes’ and ‘no’ questions?”

I give her a small nod.

“Right... did something happen to start this?”

I give her a shaky head motion.

“Right, I’ll take that as a ‘unsure’.” Charlotte says, taking a moment. “Are you changing? Like... transforming?”

I nod.

“Has this happened before?”

I shake my head.

“Ok, first time... unsure of how it started. Quick question, is it continuous? Or does the transformation come in stages?”

I take a moment, before I give her two nods, hoping that she gets the hint.

“The... second one? Continuous?” She asks, a glint in her eyes.

I nod again, feeling as though she’s getting to something.

“Then shouldn’t you be... you know, continuing to change?”

I take a moment and nod again.

“Then why isn’t your face changing?”

Again, I twist my head a little, unsure of the answer.

Charlotte takes a moment, before putting her hands up to just below my neck, pressing them against me, pushing me backwards. I take shaky steps back into the living room, Charlotte keeps her hands on my chest, looking me over. Looking back at her for a moment, silence falls upon us for a few seconds, as if she’s taking it all in.

“It... really is you, isn’t it?” She asks, and I’m unsure of how to really respond to her. After a second or two, she looks down my body again, slowly moving down my frame. Her hands trail my fur covered midsection, her fingers digging slightly into my fur. “You really do have a nice coat... mane... tail...”

‘Tail?’ I look back at my body, finding a long, black tail just above my large ass. ‘When the fuck did I get that?’

Charlotte’s thumb moves through my fur, seemingly thinking about something. I notice her take in a sniff, a small blush forming on her cheeks. She sniffs again, deeper this time, only making her blush deeper. The moment hangs in the air for a good minute, and I realise just how good it feels. Despite it being just a little action, her thumb petting my fur feels very intimate.

“You know... I’ve always liked horses.” She says, looking back at me as her hand slowly moves down to my backside, groping my rump for a second. “I always admired them. Especially stallions.”

I look back at her, not really understanding what she’s getting at.

“I... I probably shouldn’t tell you...” She says, taking yet another sniff of the air. “But, I even found this website, that does... exotic sex toys.”

I raise an eyebrow, questioning why she’s telling me about this.

“You may like what they have, they have a... ‘mare’ toy. They give names to all their products, although I’m not sure if it’s for marketing or creative purposes, or whether they just like giving them names.”

There’s not much I can do as Charlotte talks, so I just keep myself still as she continues to speak.

“Sorry, I’m rambling.” She says, looking over my body slowly. “What I’m getting at, is that they have a... stallion toy. It... comes in larger sizes...”

This takes me off guard, making me blush deeply in response.

“You know, I’ve always enjoyed the scent of horses. I don’t know why, it just... always appealed to me.” Charlotte trails off, looking over my backside slowly, before moving her face towards my body. She presses her nose against my fur, taking another sniff of me. A moan escapes her lips as she does this, taking another whiff of me. I want to question her, but even if I could form words, I stay silent, watching her as she slowly moves down below me. She stops for a moment, as if surprised by something. “Shaun, you’re hard...”

The words hit me as I try to look down at her, but with how my neck is, I can’t look back at her. This makes me half wish that my face had already changed, just for me to be able to look back at her. A couple seconds pass, before I feel an intake of breath against the bare flesh of my cock. This makes me startle a little, jolting up a little before shifting my hooves slightly.

“S-sorry, should have told you.” Charlotte says, her voice a little more timid now. “I just saw it... and I couldn’t control myself.”

I hear her take a sniff of the air, a deep whiff before a long sigh.

“There’s something in the air, Shaun...” As she says this, I feel the changes start up again, slowly moving up my head once more. This makes me groan as the pain returns to me, but there is also pleasure held within the pain. “It smells... really, really good, Shaun.”

Her words echo in my mind as I feel myself succumb to the changes, my cheek bones start to push out, my skull following suit. I call out with every creak and shift inside of my skin, huffing out deeply. Fur starts to grow out just behind of the internal changes, continuing to pierce through my flesh. Tears form in my eyes as my jaw start to thicken sideways, before pushing outwards. My jaw and skull stretches forward, forming the beginnings of a thick snout. My breath is ragged with every inch my maw grows, my nostrils flare as my nose stretches and morphs into my snout, becoming one with it.

While my skull shifts and changes beneath my skin, a pair of hands move to my length, soft fingers tracing along my sensitive flesh. Shivering softly, my cock throbs in my sister’s grasp, causing her to tighten her grip a little on me. She moves my length to the side a little, and I can just about feel her nose almost against it. A intake of breath rolls across the sensitive flesh makes me actively tremble, getting a groan to escape my lips.

“You’re in need, Shaun...” Charlotte huffs out, taking yet another whiff of my length. “How the fuck can I smell your need?”

I can hear it’s a rhetorical question, or maybe one she’s asking herself, but I still let out a small whinny in response. This gets a little chuckle out of her as my head continues to change, longer hair growing out of the top of my skull. The sweat covered mane flows down the sides of my head, mostly obscuring my view. Charlotte continues to sniff along my member, her hands travelling up and down my length. This draws a small bead of pre-cum from my tip, running down the bottom of my length.

My head resembles a horse’s more and more, pain shooting through my skull. My tongue feels thicker and bigger, becoming unbearably uncoordinated and bestial in my mouth. Groans escape my maw, trembling as my ears are the last to change, perking upwards before becoming pointed. As the last of me changes, I roll my head back, a couple of tears flow down my fur covered cheeks, marking my fur slightly.

“Do you like that, big guy?” Charlotte asks, her hands tightening even more around my cock, working me a little harder.

I let out a pain filled moan as I turn my head back towards her, whimpering out as a small whinny escapes my lips. Just barely able to see my sister, I can only watch as she works my length. It feels as though this should be wrong, and that I should question why she’s touching me like this. But her fingers working their magic, and I try my best not to really think about the situation.

“Awww, it’ll be ok, Shaun. Just focus on me, ok?”

Huffing out a little, I take a moment, trying to calm myself. I close my eyes, deciding to do as she suggests, focusing on her talented hands. This continues for a few minutes, pushing me further and deeper into my lust. After this, she moves one hand to the blunt end of my member, smearing her palm across my tip. This smears my pre-cum onto her skin, coating it in a thick layer of my pre, seemingly making Charlotte pleased.

Pulling her hand away, my ears perk as I hear the unbuckling of Charlotte’s belt, followed by the zip and button of her trousers. I can just about see my sister move her pre coated hand between her legs, before a moan escapes her lips. She actively uses my pre-cum to masturbate, her fingers diving into her folds roughly, making sure my pre gets deep into herself.

“F-fu-u-uck... Shaun, you’re... you make some good fucking lube.” Charlotte moans out, her voice shaky. “So thick and... mmph, gooey.”

I barely even register that she’s saying anything, let alone what she’s actually saying. Her hand moves away from my length, before she moves up from under me. Walking to my front, she takes her hand from her pussy, placing right into my nostrils, smearing our mixed liquids and scents against my nose. I don’t need to be told anything, already knowing what to do. Sniffing at the combined scents, I let out a deep moan after, getting another whiff of the glorious smell of our combined lusts.

“That’s a good boy, take it all in.” Charlotte moans out, her fingers dipping into my mouth.

I lick and suck on her fingers making sure to get as much of our juices gulped down. After giving me a good moment to do this, she pulls her hand out of my maw, bringing her face up to mine. Without hesitation, she locks her lips against mine, kissing me deeply as her hands come to my cheeks keeping me in place as her tongue moves into my maw. I lick and dance hers with my own, making her moan softly, before I push my thick tongue into her mouth, exploring the inside of her mouth.

This activates something deep inside of me, making me push deeper into the kiss, forcing my tongue against the back of her mouth, hitting the top of her throat. This makes Charlotte shift, gagging ever so slightly before gulping down our saliva. Despite the slight struggle, she gets back into the kiss, getting past the invasion of her throat. Our tongues dance and shift against the other’s as we gulp down our combined saliva, closing our eyes as we lose ourselves in the moment and passion between us.

“Mmmph...” Charlotte moans out, her hands moving away from my cheeks, making me open my eyes just a little.

I catch her start to undo her clothes, getting a good view of her body being revealed to me. Unable to take my gaze away from her slow stripping session, feeling my length grow harder somehow. If there is a way for it to do so, after having my sister jerk me off. Charlotte notices this, smiling softly as she is now just in her bra and underwear.

“You like that, big guy?” She asks, slowly unhooking her bra, before revealing her breasts. “Didn’t know my brother was a boob guy.”

This makes me shiver softly, my ears folding back as I look away for a moment.

“Hey,” her hand comes to my cheek, turning my snout back towards her. “You can look as much as you want. Or would you rather have a feel?”

This makes my ears go askew, as if to make sure I heard her correctly. In response to this, Charlotte places her hands under her breasts and brings them up a little. After a moment of blinking, I slowly bring my snout down, bringing my tongue to her nipple, rasping it up against the sensitive nub. She moans out a little, keeping her breasts lifted as I lick at her. This only lasts a minute or two, before she gives me a soft pet, huffing out softly. She takes a moment before pulling her underwear off, before placing the crotch piece onto my snout, giving me a full whiff of her scent again. Which I don’t waste time in inhaling, huffing at her panties as my nostrils flare out.

“You really like that scent, huh?” She asks, smiling at me. “Good boy, now, let’s give you some release, shall we?”

For the most part, I’m too preoccupied in her underwear to really care, but I still keep an eye on my sister. She slowly moves around to my side, before going below me once more. I slightly wonder what she’s doing for a moment or two, before I feel something warm and wet against the tip of my cock. For a brief moment, I think it’s her mouth, but as she pushes herself onto my length, I realise she’s pressing her pussy onto my length. Her folds stretch around the tip of my cock, a couple of seconds pass before the first couple of inches slip into her body.

Shivering at how tight she is, I let out a nicker, my cock throbbing against the inside of her pussy. Charlotte’s underwear slide off of my nose, as I thrust myself forward a little, shoving an extra inch or two of my length into my sister’s warmth. This makes her gasp and tighten around me, moving herself forward just a little.

“O-oh fuck yeah, got you nice and riled up, haven’t I?” She asks after a few moments, huffing out deeply. “Feels so much better than my dildo...”

She stays still for a few moments, and after this, I realise she maybe wants me to take control. I slowly push myself forward, being able to get another inch or two of my cock into her. This makes my sister groan out, tightening even more so around my cock. Pulling myself back out of her vagina, I get my tip to her folds, keeping it to just inside of her, before I shove myself back into her again.

Getting a few more inches back inside of her, Charlotte cries out in a mixture of pain and pleasure, shifting beneath me. While I can’t see her, I can only imagine what she’s doing beneath me, while having my attention taken away by the warm wetness surrounding my length. I start to thrust myself back and forth rhythmically, shoving myself back into her over and over. Each time I slam back into her body, I get another inch or two of my cock into her vagina, stretching her out further.

I get about a foot or so of my cock inside of my sister’s pussy, before hitting her cervix, my medial ring getting to just before her folds. A part of me wants to just enjoy the inside of Charlotte’s body, to take a few moments to properly enjoy her. But the rest of my mind overtakes me, shoving myself in and out of her even harder, slamming into her over, and over. Charlotte is just about able to keep herself in place, even if she falters a little on particularly hard thrusts.

“O-oh fuck! Shaun! You’re being so rough!” She calls out, huffing out deeply as I breed her.

My nostrils flare out as I breathe in deeply, slamming my hips down repeatedly. I lose control of myself in the depths of my sister’s body, feeling her milk my length as I ram myself back and forth. The room dissolves around me, leaving just Charlotte and I, intertwined in our incestuous breeding. I let my head hang down a little, trying to look below my barrel of a chest, zin a vague attempt to look at my sister. Although, I’m not sure whether this is to make sure she is okay, or to see if she can take more.

It doesn’t take long before I feel my orgasm start to bubble up inside of myself, my tip starts to expand inside of my sister’s body. Bringing my head back up, I grunt harder and deeper, slamming my hips down rougher, wanting to get my seed inside of her as fast as I can. I’m unable to hold myself back, feeling my motions get jerkier and more instinctive. Charlotte’s body responds to this in kind, feeling her folds repeatedly tighten and milk my length, her breaths coming out deeper as her voice goes slightly higher.

“C’mon! Cum in me! Give it to me!” She cries out, her folds clamping down on me as I feel liquid start to squirt out from her. It’s warm and just about his the bottom of my balls, given the distance between my orbs and her pussy. “O-oh fuck!”

Having her cum around my length pushes me over the edge, my tip flares out widely against my sister’s cervix, becoming a wide battering ram against the tight sphincter. I can only manage a couple last thrusts before I bury myself into her one last time, shooting my load inside of her womb. My urethra bulges as I unload my seed into my sister’s body, trying to give her every drop of my jizz. Pulling up against my body, my orbs tighten as they continue to give her their all.

We huff deeply as we work through our orgasms, our bodies shiver as we come down from our highs. My length starts going soft inside of Charlotte, quickly pulling out of her with a wet pop. This makes her gasp and shiver, before slowly coming out from under me. Her legs are visibly trembling, a small trickle of my side trailing down her inner leg.

“Oh fuck... that was fucking primal!” Charlotte says, placing her hands onto her lower abdomen. “You’re so much better than my toys, fuck... I’m so coming to you again next time.”

I nudge her softly with my snout, as I look down at her hands, watching her bones shift slightly underneath her skin. It takes a moment, but she looks down at her hands, watching them start to transform.

“F-fuck, I guess it’s starting now, huh?” She asks, not seeming to expect a response. “G-guess I’m still on my horse cock high, can’t really process it, you know?”

That makes a weird sort of sense, or maybe having a womb full of seed, assumingly on the full moon, somehow numbs the pain. Which is something I wish I knew beforehand, but I can only stay in the moment as the changes start to speed up. I stay close to her as she goes through her transformation, planning to stick by her for most of it. As much as I want another round with her, I know she needs me. So I won’t do anything, at least until she wants to.

The affects start with her hands and feet, breaking and shifting bones, before her fingers and toes merge together, followed by her nails. Somehow, the sounds of her bones changing is worse than having actively going through it myself. Perhaps it’s due to her being my sister, which makes it worse. Her hands and feet are hooves before either of us know it, before her arms and legs start to change. They soon mirror a horse’s, and the changes move up to her midsection, as fur starts to grow from her ankles.

As soon as her body starts to grow and her midsection begins to widen and thicken, she moves down onto all fours. I smile a little as I keep my eyes on her backside as it starts to grow. Muscles start to form beneath her skin, before a good amount of fat forms between the muscle and her skin. Admittedly, I am finding myself more attracted to my sister’s backside, licking my lips as it continues to grow.

“You really like my ass, don’t you, Shaun?” Charlotte asks, smiling back at me.

I give her a small nod, blushing deeply as the changes to her main body finish its changes, fur growing upwards from her legs, covering her midsection.

“Wanna have some fun? Don’t want to keep you waiting, especially when I’m not hurting.” She smiles at me.

I smile back at her, realising just how caring she is.

Charlotte sticks her ass out, her large, doughnut shaped hole clamping slightly in the warm air. This takes my full focus as her backside seems to be one of the first things to fully change, her tail pushing out from the top of the cleft of her ass. I move forward, snorting out deeply as I look down at her ass.

“Need it higher, big guy?” She asks, wiggling her ass side to side. Her feet slam onto down into the floor, her muscles tightening as she slowly stands her back end up, raising her rump up into the air. “There we are, stallion! Now... what are you gonna do with it?”

My nostrils flare as I watch her ass backside, almost hypnotised by the sight of my sister’s ass. Now that it’s within range, I move myself a little closer, my snout nudging against the side of her ass cheek. I sniff the side of her ass, taking in the smell of her sweat and natural scent. This makes me tremble deeply, my cock throbbing harder from how good she smells. Why I never knew this about her, I’ll never know.

Taking a few seconds to enjoy her rump, I shift my maw in between her ass cheeks. My lips pressed up against her perineum, my nostrils grind up against her plump hole. As I do this, I sniff her hole, her musk invading my nostrils and lungs. My eyes role back into my skull when I do this, drops of her sweat flying into my nostrils, coating the inside of my snout. I take another deep whiff of her rump, and another, and yet another. Unable to stop myself from sniffing my sister’s ass, I feel myself get drunk off of her backside musk, my mind being invaded by a thick fog of pure lust.

I turn my snout clockwise and anticlockwise, making sure I get every part of my sister’s pure musk. Pressing my snout against her hole, her anus stretches out a little bit, letting my nose dig into her warmth a little. Inhaling deeply, again, and again. I worship her ass without any hesitation, feeling her scent infest every part of my mind.

“Fuck...” Charlotte moans back at me, her voice turning softly. “D-do you love my ass that much? Or... I-is it my horse ass you enjoy?”

I can only moan back to her, taking yet another deep huff of her wonderful scent.

“Oh? Is it just the smell, hmm? Does sniffing your sister’s-oh fuck... your sister’s ass... make you hard?”

“Mmhmm...” I moan back to her, knowing that she already knows the answer, but she probably just likes knowing how she affects me.

“O-oh fuck!” Charlotte groans out as her ass cheeks clench tightly on my muzzle, keeping me in place for a few second. “There’s the pain!”

This makes me concerned a little, but I know that it’ll feel really good soon enough, maybe even better with me at her ass. My sister’s cheeks unclench, allowing me to move my snout up a little. I press my lips to her anus, watching as her hole twitch a little, before I lock my lips around her plump hole. Shoving my tongue into her hole, I suck on her equine anus as I wiggle my wet digit into her ring. Charlotte moans and groans as I do this, hearing her body shift, her bones creaking and morphing just like mine had. I tug my snout back just a little, tugging on my sister’s hole, the suction feeling amazing between the two of us. There’s a good inch or two of hole between the inside and outside of her ass.

After a few minutes of worshiping the inside of her ass, I move my tongue out of her hole, circling the wet digit around her wrinkled ring. Her plump, doughnut shaped hole feels strange against my tongue, but it’s far from an unpleasant strange. Circling clockwise, and then anticlockwise, I gather up every deep taste of her hole on my tongue, before gulping it down hungrily. It’s such a warm taste, a mix of sweat, skin, and horse musk, all mixing together inside of my maw, before I gulp it down, the taste coating the inside of my throat.

“O-oh fuck... please... t-too much!” Charlotte moans out, her voice almost sounding inhuman. “F-fuck! Oh fuck! M-my breasts! What’s happening to them?”

This perks my ears, making me pull myself away from her anus, her hole plops out from my lips as I do so. I move my snout a little lower, looking underneath her growing midsection. I watch as my sister’s breasts shrink from in between her front legs, before two large mounds form between her back legs. From my previous encounters with mares, I know that this is where equine breasts typically are. Taking a few moments to watch her new breasts come in, her nipples finally come in. I lick my lips before I move my snout under her haunches, aiming for her breasts.

My lips nibble at her nipple, my tongue lapping at her sensitive nub, getting another groan from my sister. I lick and lap at her breast, even daring to suckle at her. This makes my sister’s body tremble softly, pushing me to work a little harder at her feral breast. Moving in between one and the other, making sure to give each one the same amount of attention. After a good couple of minutes of enjoying her breasts, I press my snout between them, drawing it up to her equine pussy. Taking a deep whiff of her vagina, I continue to move up to her saliva coated anus, taking yet another whiff of her.

Letting out my breath, I slowly begin to mount her, moving my weight to my back legs as I press my chest to her back. Given I’m a little bit bigger than her, my head comes to her neck as my cock comes to her backside. My length aims up against her backside, my tip coming to her anus. Once I feel this, I press myself forward, my cock grinding up against her hole. After a second, my cock slips and grinds up against her tail, making me huff with slight annoyance.

Moving my ass back a little, before trying to thrust myself back forward again. This time, I feel a hot wetness surround my cock, a wet squelch perking my ears again. With this, Charlotte moans out, her head rolling back as she seems to try to speak, but only meaningless sounds escape her maw. I finally realise that I’ve penetrated her vagina, getting most of my length inside of her body. The last part of my resolve slowly ebbs away, even as it tells me to pull back, to get out of her depths.

But it is taken over by the equine side of me, the pure lust of the situation telling me to push further. Drawing my hips back slowly, I try to force myself out of my sister’s wet folds. But as my blunt tip gets to just within her folds, my body is taken control of, my hips thrusting harshly back into my sister’s pussy. I huff out as the feral side of my brain forces my hips back and forth, shoving my horse cock in and out of my sister’s pussy.

I move my snout up Charlotte’s neck, inhaling her bestial scent deeply, lust radiating through my body. My eyes roll back into my skull a little as I take another long sniff of her neck fur, the scent of her newfound equine body driving me crazy. My hips start to buck harder, wanting nothing more than to fill her with my seed, to flood her womb with my foals.

More and more of my cock fills her pussy, stretching her insides further, my large balls drawing closer to her wetness. The moment my orbs make contact with her folds, I tremble deeply, shivering through the pleasure that radiates through my body. I take a moment, to fully enjoy my sister’s warm, tight wetness that envelopes my whole shaft. After I properly enjoy her body, I start thrusting into her again, my balls slapping up against her pussy.

Charlotte moans out, a long whiny escaping her snout, grinding her ass back up against my inner thighs, wanting me to give her more and more of my lust. My maw shifts slightly, licking up the side of her neck, tasting her sweat coated fur. It’s a deep taste, salty and somehow sweet somehow, like popcorn. This makes me take another long lick of her neck, wanting more of her wonderful taste, craving every part of my sister’s body.

Drool slowly falls down from my lips, feeling my sister clamp down on my equine length, milking my cock almost expertly. Although, this expertise quickly devolves into an instinctive spasm around my dick. Before I know it, a thick, warm liquid squirt out against my balls every time I slam them against her clit. I can barely even process this as my sister cumming on my cock, as I feel my own orgasm build up inside of myself.

I don’t let up on my relentless barrage, slamming my hips forward over and over, forcing myself closer to orgasm. My maw opens, before I clamp my jaws down onto my sister’s neck, my nostrils flaring as my balls pull up against my body. The world around me fades to nothing, my body tensing as I give my sister one last, rough thrust. The tip of my cock flaring out against her cervix, shooting a thick load into Charlotte’s womb.

Wad after wad of my seed unloads itself into her body, bulging my urethra as each shot travels up my member. My jaws clamp down a little as I push through my orgasm as much as I can, emptying my balls slowly. But no matter how much cum I shoot into my sister, my balls never really feel any emptier. This leaves me huffing and groaning against Charlotte’s neck, my orgasm webbing away almost disappointedly. Leaving me edgy as I pull my maw away from my sister’s neck, my length quickly shrinking inside of her pussy.

I slowly un-mount her after a moment, moving away from Charlotte as she huffs and nickers. She spreads her back legs, lifting her tail a little. I watch her as my seed starts to spill out of her pussy, flowing onto the floor. Unable to look away, I stay put as she lets out a good amount of my jizz, before her back legs return to a fully upright position. Charlotte looks back at me for a moment, after which she moves around the room for a little, before finding her way to the turned over couch.

Charlotte mounts the couch, her tail flagging to the side as she looks back at me, raising her head in a little whinny. I take a moment to properly take in the scene, watching my seed flow out of her equine pussy, as her vagina winks at me. With a small huff of breath, I move myself forward, closing the distance between us, before mounting her once again. I’m already hard again, and my cum and lust covered member prods in between my sister’s ass cheeks. It takes a moment, but my blunt tip finds her anus once again.

This time around, I’m a bit more careful, pressing forward a little more attentively. Her anus resists as I push against it, just like before. But this time, I take a more careful approach, huffing out deeply. Her hole starts to stretch around my length, relenting to my equine member. I open my maw, letting out a pleasure filled whiny, her hole finally allows me to push into her bowels. The first six or so inches of my cock slips into her body, stretching her insides. Charlotte cries out in response, ending in a nickering snort, shaking her head side to side.

Pulling myself back, I press my cock back into her, getting another inch or so into her body. Repeating this over and over, I force my equine shaft deeper into my sister’s plump behind, feeling her insides relent slowly. I lose count to how many thrusts I manage to give, before my medial ring reaches her hole. This stretches her anus a little as it pushes through her hole, finally getting half of my length into her bowels.

This invigorates me to shove more of myself into her body, pulling my length out to the very tip, before slamming my cock back into her hole. Getting a couple more inches into her, I continue to thrust myself into her over and over, trying my best to thrust into her faster and harder. My front legs tighten down on the upper half of Charlotte’s own, thrusting myself ever harder into her tight hole. When my balls finally begin to slap up against her perineum, I realise just how much of my cock I’ve managed to fit into her body.

“M-mo-ore!” Charlotte cries out, her voice distorted by her new snout.

Her ass presses back up against my thrusts, trying to get more of me into her hole. This allows me to get that last part of my cock into her, spearing her fully on me. My mind melts completely into the lust coursing through me, unable to think of anything else, let alone do anything else.

I keep myself buried deep inside of my sister’s ass, feeling her hole clamp tightly around my cock. It feels so good to have my length in her rump, just enjoying the feel of her hot, damp, wonderfully tight backside. I run my maw up and down Charlotte’s neck, enjoying her warm, salty sweet scent. Running my tongue up against her throat on the second time, nickering softly at the taste running down my throat.

My orgasm fades away as my length softens inside of Charlotte’s stretched out hole, my cock pulling out of her ass. I huff deeply as I try to come to my senses, my body trembles as I stay mounted on my sister’s thick frame. After a few moments, Charlotte pushes her ass back against me again, grinding the cleft of her backside against my semi-sheathed length. This makes my nostrils flare as I sniff the musk filled air, letting out a whinny as my cock begins to harden again. Lust fills me once more, taking me over again. Despite having just cum, despite cumming more than once already. I need to cum again, to fill my sister once more... just once more.

My cock is fully erect within seconds, throbbing with need, demanding my attention. Pressing my tip against the first hole my cock can find, I slam myself forward, only now realising I’ve hit my sister’s vagina once again. My body shivers as I enter her most private area once again, letting out a nicker of pleasure as her wet warmth envelopes my entire cock once again. This makes me pull myself back to the tip, slamming back into her once again.

My motions are a lot more primal, uncoordinated, than the last time I was inside her pussy. Thrusting into her rougher and harder from the start, I am unable to do anything than breed her. It’s a fully instinctual interaction between the two of us, something taboo that only pushes me harder and deeper into my lust. Any part of my humanity has long since been orgasmed out of my body, leaving just the primal equine inside me. Charlotte is just a mare to me now, a mare that needs my foals, and every last drop of my seed.

---

The summer sun warms me as I slowly wake up, having no memory of the night before. I can already feel the warmth of another person next to me, obviously as naked as I am. Moving my hand up and down their body, I am met by their curves. A soft, if feminine moan, responding to my soft groping. Keeping my eyes closed, I draw myself closer to my unidentified partner, grinding my morning wood up against their hips. My face comes up to their breast, a soft weight that comes to my cheek.

“Mmmph... mornin’.” The stranger half mumbles their voice oddly familiar. “Fuck... still ready for more?”

This makes my eyes shoot open, raising my head for a moment, before looking to my partner, realising that I was just humping my sister’s hip. “Charlotte?!”

This makes her grimace slightly, putting a hand onto her head. “Not right against my ear, I don’t need the headache this early.”

“B-but I... you and I! W-we...”

“Fucked? Yeah, it’s not like we braided each other’s manes...” She responds, slightly annoyed.

“Th-the fuck are you talking about?” I ask, pulling away as I realise that there’s a good amount of cum pooling in between Charlotte’s legs. “What do you mean ‘manes’?”

She looks at me for a moment, questioningly looking me over. “You don’t remember, do you?”

“Remember what?”

“Well,” she spreads her legs open a little, revealing her slightly gaping pussy. “You were already mostly horse when I came over last night. It didn’t take me long to realise it was a werewolf adjacent, sort of deal. I assume you had some sort of interaction with a horse? I’m also going to assume it was some sort of bite, or should I infer that we have the same ‘love’ of horses? That lead to an exchange of... ‘fluids’?”

It takes me a minute or two to properly process what she said, remembering my visit to Tom’s farm, realising what really happened. Small snippets of the night before floods my mind, of what we did. It takes a moment, before I look over to Charlotte, unable to look away from her naked form.

“You find me, mostly transformed, and you decide to have sex with me?” I ask after a couple of seconds, unable to figure out what else to ask.

“What was I supposed to do? There wasn’t anything I could do to stop it, and trust me, you smelt like a barn yard orgy. It... got to my head.” Charlotte responds, looking away for just a second, before looking back at me. “I mean, you didn’t exactly stop yourself. If whatever sort of curse you have, affected your mind. Maybe it makes you produce pheromones? You know, so that you pass on the curse?”

“That makes sense. I mean, I’d rather think that, than think you wanted to have sex with your brother.”

Charlotte looks to the floor for a moment, before she starts to crawl over to me. I blush as she gets closer, unable to look away from her as her breasts sway from side to side softly. “And what if it was a little of both?”

I gulp as she asks this, blushing ever deeper. Charlotte moves over me, bringing her face within an inch or two of mine. This doesn’t last but a second, before she kisses me deeply, locking her lips against mine. I groan out a little at this, my cock throbbing between my legs, as if to remind me of its existence. Charlotte slowly pushes me backwards, pressing me back fully against the floor. Her knees come to either side of my hips, keeping me locked in the make-out session for a few moments. Before pulling back from the kiss, moving her upper body upright, sitting on my crotch. My length throbs against her pussy, grinding up against her outer folds.

“We keep this between us, ok? Just... you and I.” Charlotte says softly, her voice softer than usual.

“This is... isn’t right...” I say, half trying to convince myself.

“Of course it isn’t. I mean, reverse missionary? What are we thinking?” Charlotte asks, a wide smile forming on her lips. “We’re obviously have a doggy style sort of sibling relationship.”

She lets out a small chuckle at this, moving her hands to my midsection.

“You know what I mean...” I almost want to growl at her.

“You’ve already fucked me, we can’t exactly put the genie back into the bottle, Shaun.”

“But we weren’t in control...”

“Maybe, maybe not. But either way, it’s allowed us to open up a little.” Charlotte responds, moving a hand to her lower abdomen.

“So we... sh-should...?”

“Explore a little. And anyway, I am interested to see if... well, if there’s any ‘results’ from last night.”

“Results?” I half choke out, realising that she means ‘foals’. Charlotte slides my length into her pussy, making me call out in shock and taboo pleasure. She keeps me in place for a few moments, wiggling her hips side to side as she holds her gaze to mine.

“Yeah, I mean... does this curse make us infertile while we’re in our equine forms?” She asks, a glint in her eyes. “Which feels counter intuitive, in the grand scheme of things.”

“H-how do you figure? And... and how does us having sex, tell us whether you’re pregnant?”

“Werewolves, assumingly bite their pray, because they’re wolves, predatory animals. While horses... well, you know how big stallions are. As for me, us having sex doesn’t tell us whether I’m pregnant. We call this an excuse, and maybe I’m still working off the lust.”

I huff out slight annoyance as I look away for a moment, before looking back up at her. “Were you this annoying while you were a mare?”

“Probably, but I bet my pussy made it more than worth it, at the time.”

“I think you may be right...” I smirk up at her, hoping she doesn’t take me seriously.

She doesn’t, letting out a soft laugh, as she begins to slide up my length, before sitting back down on my cock. I huff out as I place my hands onto her hips, gripping her sides tightly. I bite my lip, toes curling as Charlotte rides my length. Being inside my sister, now in full control of myself, I can’t put the blame on anything else. It’s just Charlotte and me, in our incestuous act of pleasure.

Moaning out deeply, I sink into the act between us, pushing myself up into her softly, taking an active step into the passion between us. I slowly move my body upwards, bringing my midsection up against hers, moving into a sitting position. Charlotte wraps her arms around my back, holding me tight as we work together in rhythmic passion.

“I love you, Shaun.” Charlotte moans out, bringing her face against the crook of my neck.

“I love you too, Charlotte.” I groan back, groping her backside tightly as I focus on our warm and wetness.
