I didn't intend to write a m/m equine story so soon after the last one, but after seeing this amazing pic by fa!smooshkin I couldn't help myself...

Note: This story has short rapey bits at the beginning and the end, but most of it is fairly TLC.

---

“Christ, grab his leg, will ya? Didn't think he'd have this much fight left in him…" I heard my uncle Jack mutter as the bound colt kicked out feebly upon feeling a pair of strong hands land on his bare ass-cheeks.

“Give 'im one more round and we'll call it a day…" My dad replied as he grabbed one of the young stallion's legs and held it to the side. With his hands bound to the post in front of him and only one hoof on the ground, the colt couldn't put up much of a struggle as my uncle grabbed his hips and shoved himself inside the equine's already messy tail-hole.

Despite the fact that the two men had already taken him a couple of times each, the young stallion still seemed to panic at the sensation of being penetrated, his eyes rolling wildly and flecks of foam spraying from between the bit in his mouth.

“Ngghh, definitely got some fight left in him…" Jack groaned out, but this time it didn't sound like a complaint. By the way he was gripping the stallion's taped-up tail, he seemed to be enjoying the bound equines attempts to eject him from his body. The sound of smacking filed the barn as the man began to hump into the captive colt's abused rear, the noise carrying a distinctively messy quality from the loads they'd dumped inside the poor beast earlier.

Looking through a crack in the barn's wooden wall, I had to admit to mixed feelings about the whole thing. I knew the what and why, of course – my father had bought the colt at a mustang auction. There's always a handful of colts that get kicked out of one of the feral herds by the older stallions who don't want to share their mares, and to keep the feral bipeds from getting into trouble, the government rounds them up and sells them or gives them up for adoption, depending on public demand.

They're smarter than a regular animal, and can be trained to do basic farm-work, after they're broken in, of course. Which is what my father and uncle were even now doing. I knew this was considered the humane way to do it – the wild stallions would establish dominance with fights that would culminate with the looser getting mounted. After the act, neither would harbor a grudge, since to them it was normal behavior that established a peaceful hierarchy within a herd. I knew for a fact that before the study that suggested this as the only viable option for breaking feral equines, the common practice was to beat a colt, often to within an inch of his life, to ensure future obedience. And castration went without saying. Compared to that, what dad and Jack were doing didn't seem all that bad…

Still, I couldn't help but feel bad for the bound equine. Tender-heart, my dad used to call me when I was a kid, always with a hint of concealed disapproval. I doubt that I grew into the son my dad had imagined when he'd first held me in his arms. I'd recently turned eighteen, but was still quite boyish – a bit short, decidedly slim, without a hair on my face and a mane of my mother's wavy brown hair that I usually kept tied back in a pony-tail. I suppose I looked a bit girly, but couldn't really be mistaken for one, since the girls around here were country gals, and had a way of filling out jeans and shirts in a way that left little to no ambiguity.

I knew my dad wasn't really disappointed with me – I'd done great at school and would be going off to college next year, and he liked to boast how his son would be the guy paying others to break their backs for him, but I always got the impression he might have been happier with a son he had more in common with. One who could unload a truck and barely break a sweat, or one who knew how to handle the animals…

But I suppose what confused me most about the scene was my arousal. It definitely wasn't due to seeing my dad and uncle in their birthday suits. In fact, it was in spite of that, although I supposed they didn't look bad for men their age. But the moment I saw the colt being led into our ranch I though he looked majestic, and part of me wanted to ask my dad if I could help break him in. In retrospect, it was probably better that I didn't. Some of the images popping in and out of my mind told me I wouldn't have been happy just using the colt.

Which is just what my uncle was doing. He was obviously enjoying the physical sensations of the young stallion's pucker clenching around his pistoning shaft, but his stare seemed blank, a sign that he was imagining someone else in place of the struggling equine. Whatever his fantasy, it seemed to be doing the trick, since he gripped the colt harder, driving himself in and out of him in rapid, shallow thrusts before grunting as he hilted himself, grinding against the stallion's rear as he emptied his balls inside the young male for the third time that day.

“All right, let's get him bedded down and we're done…" I hear my father say as he undid the binding's on the abused colt's hands as Jack slipped his softening cock from the poor beast's pucker, their loads trickling out of the slightly gaping orifice and dripping down the stallion's prodigious sack. As the two men got dressed, I quickly scampered away so they wouldn't know I was watching the whole thing.

I didn't go far, however, and the moment the two were gone I unbolted the door and snuck back into the barn. I made my way towards the stall the two had made for him, the raw planks making it stand out against the aged wood of the barn. Peering over the door, I felt my heart pick up at the sight of the colt huddled up on his bed – a pile of straw covered by an old blanket.

He was a pinto, his short coat mostly coppery brown with splashes of white, and a black mane and tail, both of which looked quite tangled. I was surprised again by the obvious arousal the sight of the lean stallion inspired in me, having never reacted to a male this way before. Although truth be told it, my romantic life wasn't very eventful. I had always been better looking than most of the boys around, but I seemed to stay boyish while they turned into men, and the girls' interests seemed to change as well.

But more than anything I felt pity for the poor thing, curled up and seeming to stare at nothing as semen continued to leak from beneath his taped-up tail. Well, I supposed I could at least stop him from sleeping in a puddle of spunk. The sound of the latch of his stall door being undone made him snap his head up, ears perking up at first then falling timidly to his sides at the sight of another human, albeit a smaller specimen.

“It's OK boy, I'm not gonna hurt you…" I said, crouching down so I wouldn't be as intimidating. I could see his nostrils flaring as he took in my scent, noting I was someone new. He was still apprehensive, but seemed less frightened, and I took that as a good sign. I gently put my hand on his shoulder and stroked his arm, admiring the hard muscles my finger's slid over. He still had a lean, coltish build, and even though his muscles weren't bulging, you could see them ripple and flex even beneath his fur.

“C'mon, let's get you cleaned up." I said, getting up and motioning to the colt to do the same. He eventually did, rising up on shaky legs and looking worried about what's to follow.

He was doing his best to look small and submissive, but even so he stood taller than me. His shoulders were only several inches higher than mine, but with that long, graceful neck he must be at least a six footer when standing up straight. I saw him glance worriedly at the bit and bridle hanging near the stall, but I had no intention of putting them on him. Taking him gently by the hand, I led him to the corner of the barn, noting with some satisfaction that confusion seemed to replace the fear on his equine visage.

Since the bathrooms in our house were on the top floor, and my father couldn't get up there without tracking any dirt along the way he'd made a simple shower in the barn – nothing but an old tin showerhead connected to the rainwater cistern in the loft, and a metal grate beneath to let the water drain away. It was late afternoon and I knew the late-spring sun beating down on the roof will have made it nice and warm by now.

When we got to the grate I gave the chain a short pull, causing a cascade of warm water to rain down, almost startling the colt next to me. I did it again, holding my arm under the stream to show him it was harmless. The young stallion tentatively stretched out his own arm, seeming to relax as the water soaked into his dusty coat. He gave it a sniff before sticking his muzzle under the spray, and seconds later he'd stepped beneath it, nickering in pleasure as the warm water cascaded over his lean body.

I smiled at his enthusiasm, and noticing an old chunk of lye soap on a nearby stand decided I might as well give him a good wash, since he seemed to enjoy it. After he was good and soaked I turned off the water and approached him with the soap. The colt seemed disappointed that the water was gone, and looked at the pale bar in my hand suspiciously. He sniffed the soap, and apparently finding the smell inoffensive enough gave it a tentative lick. I couldn't help but grin at the expression on his face after he did.

“Yeah, I made the same face the first time I used a swear word in front of my mother…" I said as I began to rub the bar against his shoulder. The colt didn't seem to mind the attention but when I did his neck he made sure to raise his head, keeping his mouth as far away from the bar as possible. Rubbing the hard bar against his soaked fur, I was working up a nice lather, I almost didn't notice the way I was biting my lower lip by the time I got to his chest.

I could feel his muscles twitch beneath my fingertips, that powerful chest rising and falling with every deep breath the stallion took. I was breathing pretty heavily myself by then, and the fact that every breath carried the smell of the equine's wet fur wasn't helping me keep a clear head. After I did his arms I moved to his abs, marveling at the colt's hard, rippling muscles as I ran my hands over them. It was when I looked below that toned surface that I lost my breath.

The stallion must have been enjoying his bath more than I'd realized, since I could now see his mottled pink shaft slowly emerging from his sheath. For a few seconds I just stood there, mesmerized, as itch after thick inch began to slip out. I could feel my own body responding, and even though I didn't fully understand it, I could no longer deny the effect the sight of the naked colt was having on me.

“Well… I suppose you need washing there too…" I said, wondering if I was fooling the horse, because I certainly wasn't fooling myself.

I gently brushed my fingers over the soft shaft, noting the way the colt seemed to flinch at first, before allowing me to continue. The cock was still soft, but it was massive, with eight inches already out and more seemingly on the way. The thing felt alive in my hand, seeming to respond to every touch and rub as its pink-and-black color quickly disappeared beneath the lather. I reached out with my other hand to touch… I mean wash… the heavy pouch hanging behind the equine appendage, and I was amazed by the weight of in in my hand. His balls were so big I could only fit one in my palm!

I'm not sure how long I spend gently and diligently cleaning the colt's privates, but by the time a surprisingly powerful snort from the animal snapped me back to reality I'd realized that he had a foot-long shaft dangling between his legs. There was something about that snort that made me blush as I quickly got back to cleaning the rest of the stallion. Of course the next part was his legs and calves, which meant by the time I was done with it I'd spent some time face to face with his stiffening cock.

It took more willpower than I'd like to admit to tear my eyes off that swinging length, but I did eventually manage to get back up. Giving the colt's maleness one last look, I slowly walked up behind him and began to do his back. Even though I could no longer see his erection, running my hands all over his toned body did little to help the tent in my shorts. By the time I'd moved on to his waist, I'd noticed he'd tensed up again.

“Don't worry boy, I'm just going to clean you up…" I spoke to him softly and he seemed to relax a little, remembering it was me behind him.

After I undid the vet-tape, I did my best to get the tangles out of his tail, lathering up the soggy length of black hair as I did. When I lifted it out of the way I could see his cheeks tense and clench up, but as I ran my hand over them gently he relaxed enough for me to slide a finger between them. I made sure to be as gentle as possible as I ran my soapy digit over his abused pucker, feeling it clench shut at my touch.

As I washed that firm behind, I wondered briefly how it would feel to mount it. The idea of forcing myself on the colt was intensely unappealing, but I wondered what it would be like if I found him raising his tail, craning that long neck and showing an equine visage with desire clearly written all over it. As arousing as that thought was, when I imagined the reverse – me bent over and presented to the eager stud behind me, my heart nearly skipped a beat.

I quickly began the struggle to think of anything else as I finished soaping up the colt before turning the shower on again and rinsing the suds from his chiseled body. He shook under the warm spray, almost prancing as he seemed to delight in the sensation of being scrubbed clean. After I'd switched the water off, I grabbed an old towel and began to dry him off. I told myself it was so that he didn't get his blanket soaked and maybe catch a cold from sleeping on wet bedding, but in retrospect, I think I just wanted to feel his body up again, even if it was through the fabric of a towel.

I was doing fine up to the point where I knelt to do his thighs and came face to face with his still dangling member. My eyes were instantly riveted to the veiny, mottled shaft, nostrils flaring visibly to catch his scent. The clean smell of soap was already giving way to a sweet-smelling musk that was so enticing that I found myself actually sniffing the heavy length. My hand rose as if on its own, fingertips trailing gently down the twitching shaft, this time without any pretense of hygiene.

The colt snorted and I saw the cock twitch and slowly become erect at my touch. I felt a strange thrill at the knowledge that I was doing it, that I was arousing this glorious creature standing before me. The next thing I knew my hand was wrapped around the girthy appendage and I was slowly stroking the stallion's length, feeling it throb and firm up as the equine snorted in approval. Before I knew it, it had risen to the point that the slightly flared head was pointed straight at my face. As I stood transfixed by the sight of it, a particularly strong twitch traveled along the meaty length and a splash of something warm and clear hit me right in the face.

Blinking in surprise, I felt a fog settle over my brain as I breathed in more of the colt's intoxicating scent, my tongue sliding out of my mouth to lick some of the pre off my lips. Before I realized what I was doing, I'd brought my mouth an inch from the colt's cock and was running my tongue over the blunt tip of his shaft. I saw him shudder from the sensation and felt his shaft flex in my grip, which only seemed to spur me on.

A moment later I was licking and kissing the meaty length all over, my own cock almost painfully erect as I began to service the young stallion standing in front of me. My other hand drifted lower along the shaft, trailing over the thick base of it before it settled on the equine's hefty sack. I actually moaned when I once again felt the weight of it in my hand, wondering if the colt had ever come before. I realized then that I'd decided at some point that I'd make him come, but for the life of me, I couldn't remember when…

Working my way lovingly up his throbbing, and by now quite erect shaft, I was once again face to face with that flared, spurting tip. Considering I could only barely close my hand around the narrowest part of the stallion's cock, I was certain there was no way I could fit it in my mouth while avoiding my teeth, something I instinctively knew was important. Instead, I just pressed my mouth to the blunt tip and sealed my lips around it, suckling gently as one hand stroked the colt's spit-slicked shaft while the other one fondled his bulging sack.

I knew I was doing a good job both by the pre spurting into my eager mouth, and the twitching of the equines hips and rear as he struggled against the instinct to buck. I looked up without slowing my pace, only to meet the colt's eyes, the big brown orbs seeming dimmed by the same lust mine were. There was no doubt that he was enjoying this, his mouth hanging open and his powerful, muscled chest heaving with every panting breath he took.

I shuddered a little, moaning around the horseflesh pressed against my mouth as that same thrill ran through me at the sight of the colt's lusty gaze. The smell and taste of him only spurred me on, and by now I was suckling wantonly on his shaft, fondling his balls and awaiting eagerly for the load I knew they would soon be shooting out of it. The other hand was now rapidly gliding along the throbbing shaft, gently squeezing it every now and then, feeling the hardness of it beneath its silky surface.

The colt snorted above me, but I knew what was coming even without that sound. His tip was mushrooming up before my eyes, getting twice as big even as his sack pulled up, those heavy orbs leaving my hand as they prepared to unburden themselves. I didn't even need to think about what I'd do next. Gripping the mottled shaft with both hands, I kept it steady as the mustang bucked a few times, feeling the pulse travel along the underside before it reached the tip.

I was ready for the first spurt, swallowing it down eagerly and moaning at the sensation of the warm, silky goo traveling down my gullet. I was surprised by how fast the second blast came, but I managed to swallow it down as well. The third had shot straight down my throat, causing me to choke and sputter as I pulled my mouth off the flared tip, leaving the following spurts to land over my face and chest. The colt didn't seem disappointed, almost whinnying in his climax, his tail flagging with every warm ribbon that landed on my bare skin.

As I caught my breath, I'd realized my hands hand been working the colt's shaft all the time, milking his meaty length of every last pearly drop. As the last spurt landed just below my chin, I could feel the majestic rod slowly begin to soften in my grip, the flare looking huge as it continued to drool a bit of the stallion's seed.

I rose up slowly, surprised at how shaky my legs felt, and looked up into the panting equine's visage, noting the way those warm brown eyes seemed glued to the mess he'd made on me. I could feel my own shaft twitch just from the way he looked at me, my tongue slipping out to lick his cum off my lips. I realized I either liked the way he tasted, or that I was too horny to care, and a moment later I was running a finger along my collar bone, scooping up some more of his spunk before slipping the digit into my eager mouth.

The mustang's eyes seemed to widen a little at the sight, his hand rising up tentatively, one hoof-nailed finger trailing along my chest and gathering up some of his goo. He lifted it up, but seemed hesitant to bring it any closer to my face. Without any such hesitation, I closed my lips over the dripping digit, suckling it gently before letting it slide out of my mouth. That seemed to ease him a little, and with his help, I was clean all too soon.

As reluctant as I was to leave the colt, the last thing I wanted was for someone to start wondering where I was. With that in mind I put my shirt back on before leading the stallion back to his stall. The young equine did look a bit wistful as I latched the door shut, but the sight of the blanket-covered pile of straw seemed more attractive to him than I was at the moment. He'd made himself comfortable and seemed to fall asleep the moment his head hit the hay. Well, straw…

I'd managed to get to the house and even the bathroom without anyone spotting me. I immediately got into the shower, intent on washing off the scent of a stallion. The colt's musk was still all I could smell and I was certain others would pick it up as well. But first things first, there was my own neglected manhood to think about.

Thinking seemed almost enough to do the trick, and after a few strokes I was cumming so hard my legs buckled as I sprayed the tiles in front of me. The rest of the evening proved uneventful, but my dreams were anything but. It seemed that every time I closed my eyes, I was back in the stable, back on my knees with the colt either in front of me, or sometimes behind. What little sleep I could get was restless, and by the time I'd tossed and turned myself awake for about the fifth time only to find it was about one in the morning I gave up on it.

There was something I needed more than sleep, and I knew where to find it. I easily made my way through the sleepy house and back into the barn, my heart already pounding in my chest and any trace of drowsiness driven away by a surge of arousal. Seconds after I'd turned on the lights, I heard a shuffling coming from the mustang's stall as the equine slowly got up on his hooves. His sleepy eyes seemed to widen a bit as they focused on me, pointed ears pricking up as he gave a low nicker. Apparently he hadn't forgotten our previous meeting.

“Well, you seem glad to see me…" I said nervously, feeling a little less guilty about waking the sleeping stallion. For his part, he seemed quite eager as well, giving a little snort as he put his hands on top of the stall door.

I bit my lower lip at the sight of the colt, taking in a deep breath of the stallion-laced air as I made a decision. I quickly removed the t-shirt and boxers I'd been sleeping in, baring my body to the equines curious eyes. I couldn't help but grin at his reaction to my naked form as the colt actually tossed his head, the spitting image of an eager breeding stud. Still feeling nervous about the choice I made, but too aroused to really care, I made my way to the stall and let him out. The first thing the colt did once he was out was to clop over to my side and begin sniffing me around the mouth and neck, nostrils flaring widely as he tried without success to pick up his scent on me.

“Sorry boy, I had to have a wash too. I love the way you smell, but I couldn't risk having anyone else smell you on me…" I said, feeling genuine regret that I couldn't walk around carrying this glorious beast's musk on my skin.

As he nuzzled my neck I shuddered from the warm puffs of air on my bare skin, my hand rising to trace the line of his long, slender neck. I marveled again at the strength I felt beneath the fine coat, the raw power contained in such a graceful body. As I slowly slid a finger down the line where bronze fur met cream, I felt something warm and silky brush against my thigh. Sliding my other hand between us, my fingertips soon brushed against the now familiar veiny texture of the colt's hardening shaft.

The mustang seemed to remember our earlier encounter, and after only a few loving strokes, the throbbing length was already fully erect and twitching in my gentle grip. As he continued to nuzzle my neck, I dug my fingers into his thick black mane, pressing my body against his and consequently my slim shaft against the throbbing equine spire. As the colt began to gently run his hands along my naked body, part of me wanted to stay like this forever, or at least until dawn, but it wasn't a desire to cuddle that got me out here in the middle of the night.

I reluctantly pulled away from the affectionate equine, taking a moment to look into his deep brown eyes before looking down. Eyes trailing along that finely sculpted chest, I was soon faced with the sight of our shafts, noting how absurdly small mine looked next to the stallion's twitching spire. Well, all the more fitting that he get the male role.

Taking a deep breath to steel myself, I turned away from the colt and put my hands on the door of his stall. Bracing myself, I parted my legs and arched my back, blushing a little as I thrust my ass out towards the equine, my cheeks parting slightly to present him with a glimpse of my virgin pucker. I looked behind me, not sure if he would get the meaning of my gesture, but one glance at the expression of his face told me that he got the message perfectly.

As the eager stallion took a few steps towards me I turned my head forward again, gripping the door as I braced myself. My heart began to beat wildly in my chest and I drew in a shuddering gasp when I felt the colt's hands on my out-thrust rump, those hoof-nailed fingers digging into the soft flesh of my ass as he spread my cheeks open.

Panic gripped me as I began to wonder if I had just made a huge mistake. I've never had anything up my ass before, and as attractive as the stallion's cock was it was also massive, and I began to worry about just how badly I could get hurt. I did my best to relax, knowing that there was no stopping this now and that tensing up would only make things worse. I was certain that at any moment now I would feel that blunt head prodding at my rear, battering at my entrance as the mustang's powerful hips bucked, driven by the instinct to breed.

When something warm and wet pressed against my pucker I shut my eyes and held my breath, but let it out a moment later as something moist and silky ran along the crack of my ass. I was panting, shocked by the strange sensation to the point that my legs almost buckled when I felt it again. Whipping my head back, I saw the mustang kneeling, eyes closed and his muzzle buried between my cheeks. A shuddering moan escaped me as that tongue once again slid across my pucker, pressing just a bit against the opening, coaxing it to relax and open.

Well, at least one of us had some sense. The tender attention was something I never expected from the biped equine, but the gesture did what it was no doubt intended to do, dispelling all of my fear and tension and allowing me to relax. As part of me did just that as the colt's tongue slipped just a little bit deeper with every swipe, my toes curling from the sensation. My heart fluttered in my chest as I realized what he was doing – teasing his mare and preparing her for a breeding.

The same desire that lured me to the barn was back in full force, and I was soon moaning every time that thick, broad tongue slipped a little further inside me, thrusting my rear out as far as I could to give the stallion even more access. He seemed to note my eagerness, his hands now gently groping my cheeks even as they kept them spread as wide as possible as that tongue worked tirelessly, slickening and stretching my rosebud.

I almost whined out loud when that tongue withdrew, leaving my pucker clenching forlornly and making me realize I must look very much like a winking mare from where the mustang was standing. Sure enough, a moment later I felt one hand leave my ass as the other slid up until it was resting on my hip. I looked back in time to see the colt grasp his shaft and carefully guide it until the flared tip was pressed against my twitching pucker.

The equine just held himself there, his squirting head pressed firmly against me, helping slicken me up even more. Doing my best to relax, I focused on pushing out a little with the muscles in my rear, and soon felt my pucker open out around the stallion's glans. The colt seemed to instinctively recognize that behavior, and with one little buck of his hips he'd popped the whole trumpet-like head of his mottled cock into me.

I squealed out a little, surprised by the sudden intrusion into my no longer virgin rear. I'd never imagined that he'd be able to enter me so suddenly, and I couldn't help but wince at the pain of my deflowering. It seemed like a throbbing pain at first, but once I managed to relax my clenching pucker I realized it was just a sharp sting, and that the throbbing I was feeling was in fact the stallion's heartbeat. The colt's cock kept leaking per inside me, as if to eager to put out the burning sensation in my ass, and I soon found myself relaxing, the pain fading into mere discomfort.

As it did, it allowed me to focus on the sensation of fullness, the delicious feeling of having that warm, throbbing organ lodged inside me. Taking deep breaths I'd managed to relax and feeling ready for more, I thrust out my ass out, urging my stallion on. He nickered in apparent approval, placing both hands firmly on my cheeks as he slowly fed in more and more of his mottled shaft. As I felt inch after thick inch slowly slide deeper into me, I realized taking that flared tip was the worst part, and found myself enjoying the sensation of that hard rod slowly claiming my body as my pucker clung lovingly to its veiny length.

I was amazed at how patient and gentle the colt was being. Part of me had worried that he might just mount me and start breeding me with the same consideration a four-legged equine would give a mare. But his progress was slow and steady, to the point I was surprised when I felt the ridge of his medial ring press against my pucker a moment before it slipped in, making my ass clench lovingly around him. Every time I did that, something inside me seemed to rub against the twitching shaft, making my own cock flex and drool. And the huff of air I felt against my bare back every time I did told me that it must feel nice for the colt as well.

I felt myself being stretched out a little further, realizing I'd taken the thicker base of the stallion's shaft only when I felt his large sack bump against mine, the equine letting out a snort of satisfaction at having hilted his mare. I felt strangely giddy at the thought that I'd managed to take the mustang's whole length, running one hand gently across my trim stomach, almost expecting to feel the outline of the stallion's cock beneath my skin.

The colt gave my cheeks a possessive grope, seeming content to rest a little and let me adjust to having him inside me. I found myself almost growing a little impatient, squeezing my pucker and milking that hot, hard length while at the same time rubbing my insides against it. After about a minute of that, I felt that glorious length slowly withdraw until only the head was still lodged in my quivering body. A moment later, the colt behind me reversed direction, and I could feel every contour on the equine length as it was once again fed into my eager rear.

The stallion soon set a steady rhythm, drawing almost all the way out before pushing himself back in and reclaiming my ass. I began to moan out with every stroke as I realized this was it – I was being fucked by a feral two-legged stallion, bent over and begging to be bred like a mare in heat. I guess I must have sounded like one at that point, since my cries of pleasure definitely encouraged the mustang, making him push a little harder every time he sheathed himself, to the point that I would actually rise on the tips of my toes every time he bottomed out inside me.

Since the almost whorish sounds I was making left no doubt I was enjoying myself, the colt breeding my ass began to buck into me, his powerful hips smacking into my ass every time that shaft was hilted in my ass. Every time his body slapped against my rump I could feel my insides clench, milking the equine length throbbing inside me. And the more I milked his shaft, the messier and wetter the sounds of our mating got, to the point that the cheeks on my face were as red as imagined the cheeks of my ass must be.

I stood there moaning as I was bred, staring blankly ahead as I babbled, occasional words of praise and encouragement getting past my lips between the squeals and gasps. The colt behind me was now pistoning like a machine, strong hands wrapped firmly around my waist even as my insides wrapped around his cock. I could feel my own member, almost painfully erect now and slapping messily against my belly, drooling constantly even though I hadn't even touched it.

Nor did I intend to. Being fucked felt more amazing than I dreamed of, and I was perversely curious to see if I could actually come just from having my rear bred, like a proper mare. I wondered how much longer the stallion humping into me could last, my heartbeat speeding up at the thought of him cumming inside me. I remembered how much I'd swallowed when I'd sucked him off, and how he'd painted me with what I couldn't take. Now, there would be only one way for all that stallion seed to go…

I heard the colt behind me snort just as his grip on me tightened and he began to speed up. I braced myself against the stall door as the mustang began to thrust rapidly into me, pulling back until his medial ring was only barely outside me before smacking into me with enough force to push my whole body forward. That same ring that was rubbing against the sensitive spot inside me was now flicking against it so rapidly that my eyes actually rolled back in my head, my mouth hanging open but without any sound coming from it.

I realized then that the stallion wasn't really fucking me earlier. That had been tender lovemaking compared to the wild rutting my ass was receiving now, as the equine bucked into it with wild abandon, actually pulling my rear back to meet every jack-hammer thrust. I let out a long moan which shook with every smack of the horses hips against my pert rear. My legs buckled beneath me but the colt didn't seem to notice, holding me up easily by my waist as he grunted behind me. As the scent of a rutting stallion reached me I realized he must be working up a sweat, pounding into me with every ounce of strength held in that toned body.

I felt myself tantalizingly close to a mind-shattering orgasm, waiting for one thing to set it off. Once I no longer felt the mustang's heavy sack bumping against my own, I knew my wait was almost over. I could feel that tip mushrooming up inside me, a twinge of pain registering past the sheer ecstasy as I held my breath.

I heard the colt's whinny as I felt his shaft swell a split second before the tip erupted and a warm sensation began to spread through me. The feeling of the colt cumming inside me, breeding me like a filly in her first heat send me over the edge, every twitch and throb of my spurting cock only milking more of the stallion's seed as he emptied his more impressive sack into my ass. My pucker was clenching so tightly around the equine length that every drop the mustang shot stayed inside me, jet after thick jet of hot, virile stallion spunk.

As the throbbing length lodged inside me continued to drool I felt a puff of warm air against the back of my neck as the colt nuzzled me affectionately, keeping himself hilted in my still twitching ass. I panted happily, every breath laced with the colt's musk as his cock slowly softened inside me. The mustang seemed as reluctant as I was to see this moment end, staying with me until his receding shaft slipped out of me with a lewdly wet noise. The sudden emptiness left me feeling slightly sad, but at the same time there was a thrilling sense of completion as I felt the colt's warm seed trickle out of my well-bred pucker and drip down my sack.

As much as part of me wanted to snuggle up with the gorgeous colt on that pile of straw, I knew I had to head back home and get at least a little bit of sleep. Turning around, I trailed my hand along the stallion's delicate muzzle before getting him back into the stall and getting dressed. As I walked out I did my best to clench my pucker up, telling myself it was to stop the stallion spunk from dribbling down my leg and making a mess in the house, but I knew deep down I just wanted to keep it inside me for as long as I could.

“Ungh! I still can't believe how well this worked…" I heard my father exclaim, grunting as he buried his cock under the colt's tail for the second time. His hands were bound, but both men had remarked that they needn't have bothered – the mustang seemed docile today, stoically enduring the penetration as if it was an old routine.

“Strange, I know. But I guess it's just their natural way of learnin' who's boss…" my uncle remarked, his cock softening after having just been pulled out of the young stallion's rear.

I couldn't help grin at that last part, since I knew the lesson the colt had really learned – if you endure being mounted during the day, at night you get a mare…
