Author's Notes: A variant of this story was originally posted some time around 2004-2006 by the person whom I collaborated with to write it, though much like my situation they too have wiped their presence from the furry community and moved on with their life. Out of respect for their privacy, I will not disclose their name. This is not that exact story but is instead based on it. I don't have a concise year as to when this was actually written; this version is built around an outline with a file creation date of 2004 recovered from a floppy disk, but 2004 somehow just feels a bit too early to me so while I don't doubt the veracity of the file date I want to say this story was likely kicking around for quite some time before it was eventually finished and posted. It's about 20 years old.

There is nothing particularly special or noteworthy about this story that prompted me to want to touch it up and post it, I've just been working on several different writing projects at any given time and this is just the next one in line that's been finished and made ready to post. This is another horse story, echoes of Kink Crew (my first post as Viscosisaurus) I guess. I am not really trying to make this the "thing" I am known for or anything like that. If you could only see the catalog of ideas and outlines I've amassed over the past 25 years it would scare the hell out of you. I'm literally just picking things at random and dusting them off.

The sun was starting to set on another summer day. Lou, a middle-aged farmer who maintained a reasonable plot of land on his own, was pulling his diesel tractor into the garage. As the machinery came to a stop under the tin roof he set the brake and dismounted the driver's seat. As usual, the keys were simply left in the ignition as there was no one else there to use it. They would be waiting for him tomorrow as always. On his way across the driveway Lou passed by the small stable and accompanying stretch of barbed wire fence surrounding the chunk of land it sat on. Waiting by part of the fence was a horse who'd been summoned by the sounds of the tractor pulling into the garage and parking.

"Hey there girl," Lou said as he walked up to the horse and gently rubbed the front of her muzzle. The horse responded by swishing her head and fluttering her ears before reaching out to nip at his shirt with her front teeth.

Lou spent a few minutes at the fence patting the horse and talking to her before turning his attention back to the farmhouse where he made his way inside and took his boots off. The rest of the evening was uneventful as always. Lou cleaned himself up in the shower, shaved, made a quick dinner, and spent the time before he went to sleep watching the local news and the first half of an action movie that he remembered from his youth some 30 years ago. The commercials padded the runtime out too long and before Lou realized he was about to fall asleep on his couch he mustered the energy to rouse himself and retreat to his bedroom for the night.

At 6:00am on the dot the alarm clock next to Lou's bed rang, the harsh electronic beeps instantly walking him up. Lou shut off the alarm and dutifully got out of bed to put a pot of coffee on the brewer and start getting ready for the day ahead. The itinerary wasn't too bad, today was to be the day that Lou would tidy up the barn and stable and groom the animals, something that had needed to be done for a few days by that point. After an ample breakfast and several cups of coffee Lou collected his things and got started taking care of business.

He started in the barn since that needed the most work. The two cows that Lou kept were generally disinterested in what he was doing and spent most of the time sitting in the shade provided by the trees outside. He cleaned the floors, topped off the feed trough, and cycled the water in the concrete well. Once the cows saw Lou refilling their food they sauntered over to have a snack. Lou gave each of them a light brushing and checked them over for anything out of the ordinary before finishing up and heading over to the stable to do much of the same for the horse.

Unlike the cows, Lou's horse was always pleased to see him. As Lou approached the stable he hollered out the horse's name, Grace, and a few moments later she poked her head out of the window on the side of the building to greet him. As Lou entered the stable through the main door she walked over to the inner fence where she received another patting and half of an apple that Lou had sliced up earlier that morning and kept in a plastic bag. As Lou tried to work in the stable Grace would occasionally nose around and inspect Lou, what he was doing, and the things he brought into the stable with him. Whereas the cattle were content to rest outside, Grace wanted to be part of whatever was going on, always. Lou had picked up Grace and the other animals at the farm many years ago, at least over a decade. He didn't really have any plans to sell milk or make butter, or learn to ride a horse though. "Having animals" was just something that sort of came with the territory of working the land and after a few harvest seasons of working alone Lou figured he could use some company.

Lou eventually sat down to take a break and cool off. He watched Grace for a while, his thoughts freely wandering. After several minutes Lou got back up and walked over to the mare and gently stroked her neck a few times. He gradually worked his way down her side as he walked along her figure and stopped when he reached her hindquarters. For a while now, at least a couple of years, Lou had found himself becoming a little more fond of Grace. He'd begun to be curious about her in ways that one side of him knew were taboo. After several decades of occasional one night flings with people at the local bar and hopeful connections that went nowhere Lou had gradually become more personal and reserved. Save for his trips into town to get supplies and sometimes catching the football game at the bar Grace and the rest of the animals on the land were Lou's usual company. Grace was always happy to see him, and as time went on Lou found himself happy to see her too.

The farmer ran his hand along the back of one of Grace's thighs before reaching inward to gently stroke the mare's vagina. Grace's pelvic muscles twitched lightly in response to the touch and she swished her tail a couple of times, not seeming to mind the contact. Lou had experimentally felt Grace a few times before, so this wasn't really anything new to her. He lightly pressed two fingers against her opening and watched as they effortlessly dipped inside. As his fingers probed the mare Lou could feel his arousal building so he unbuttoned his pants and pulled his underwear down a bit to let his erect manhood out. He went back to massaging and fingering Grace's vagina while slowly stroking his shaft with his other hand.

A few minutes passed and Lou felt himself wanting to take things a step further. He'd fingered Grace while pleasuring himself before, but every time he did so he wanted to know what it would feel like to take her. Cooler heads would always prevail though and Lou was content to finish before going that far. As Lou moved around behind Grace however, this time would be different.

The farmer positioned himself behind his horse holding his shaft in one hand. As he looked down at the wrinkly lips of Grace's womanhood Lou could feel his heart racing. Gently, he pressed the head of his shaft against her, meeting a little bit of resistance as she tightened up reflexively. Lou pulled back a bit and rubbed his tip along her lips a couple of times before pushing forward and trying to enter her again. This time Grace had relaxed and Lou watched as his length disappeared into her, the farmer letting out a surprised gasp as Grace's warmth wrapped around him. There was an obvious difference in size but he could still feel the walls of the mare's canal part slightly to accommodate him.

Lou trembled in pleasure for a split second as he held himself in place before pulling back slightly and thrusting forward into Grace. He placed his hands on either side of her hindquarters as he took in the feelings of the mare's intimate flesh enveloping his member. He moaned as he thrust himself into her several more times before slowly withdrawing himself from her folds. Lou reached down to his shaft and brought himself to climax, not yet having the nerve to fully commit to the deed and finish inside of the mare. He sighed pleasurably as he reached his peak, his cock pulsing in his hand as it released several small ropes of seed onto the hay covering the floor of the stable.

Lou tucked his softening member back into his pants and refastened them. He walked back up to Grace's front and stroked her neck gently a while more before giving her a soft hug. He resumed his work in the stable before eventually packing everything up and heading back into the farmhouse for the evening. He showered, ate dinner, watched the news, and did the same usual things before checking into bed.

The next couple of days saw Lou working with his tractor again raking seed lines in the dirt of his property in preparation for the season ahead. He passed by the stable as he went about his business but didn't really spend much of any time inside, though despite this Grace was always on his mind. Having now known her intimately she was all he could think about as he drove back and forth making long passes on his tractor tilling up the dirt. Later one evening while watching television Lou found himself unable to focus on the show because he couldn't stop thinking about the mare in the stable. The crotch of his lounge shorts tented out slightly as his semi-erect member pressed against the fabric. Seeking release from the thoughts Lou roused himself from the couch, slipped on his shoes, and made his way outside toward the stable.

Grace wasn't around since she wasn't used to seeing Lou when it was dark outside, but all it took was one loud and swift whistle to get her attention and bring her over. Lou felt himself become excited in a way he hadn't known before as he watched her trot in his direction. He reached out to stroke her muzzle and gave her another gentle hug.

"Hey girl," he said as he greeted her. Grace whinnied and flicked her ears a couple of times, nipping at Lou's shirt a bit as she was so fond of doing.

The farmer spent several minutes bonding with the mare before making his way back behind her once again. He reached down to trace her lips with his fingers guiding his middle one inside to ready her before pulling his shorts down and letting his firm shaft hang outward. He stepped up to Grace's backside and rubbed the head of his cock against her lips before pushing forward and guiding it into her with his hand. Lou sighed and placed his hands on the mare's rump as he slid into Grace and let her familiar warmth envelope his length once more.

Lou began a slow pace of thrusting into the mare and savoring the feeling of her soft folds stroking his shaft. Grace didn't really feel too different from a woman but Lou found himself enjoying just how much more of her there was to take in. The act of taking her was unique to him; the position, the surroundings, even the feeling of her short fur in the palms of his hands. In that regard Grace was unlike any woman Lou had been with and the change of pace was exhilarating. Lou had started increasing his pace bit by bit, the motions of his member plunging into the horse now making barely audible sucking sounds as the air getting trapped inside of Grace's vaginal canal pushed out around Lou's shaft.

Lou could feel his climax approaching causing his pace to dip a bit as he realized he was really about to do this. The farmer moaned as he pushed himself deep into the mare one last time and peaked. Lou's fingers gently dug into the fur of Grace's backside as his cock throbbed and released his seed into her, though given the size difference between the two it didn't stay inside of her and quickly dribbled down over her clitoris onto the hay below them. Lou held himself inside of Grace for several moments as he caught his breath before slowly pulling out of her. As he pulled his shorts back up he noticed the sight of his own cum dripping out of the mare. There was a certain thrill to it, the thought of raw sex without the scare of the usual consequences.

Lou gave Grace a tighter hug than usual and planted a soft kiss on the front of her muzzle before he headed back to the house to sleep.

For the next several days Lou's mind was filled with racy thoughts about his horse. He visited her a few more times after sundown and after three or so off and on nights of romance Grace started hanging around a little closer to the stable at night expecting the attention.

One evening while washing up in the shower Lou once again started fantasizing about Grace and began idly stroking himself as he cleaned up. As he felt his shaft however he could swear it felt bigger than usual. Not to any great degree but just enough that after spending decades of masturbating like a normal guy the organ just felt "different" in his hand. After finishing his shower Lou fetched a ruler from the junk drawer of his kitchen and held it beside his cock. At one point in his youth he'd earnestly measured it like all men do but had long forgotten whatever it actually was back then. Right now though, as Lou stood in his kitchen with his pants down, his shaft was a little past five and a half inches. The farmer shrugged and put the ruler away before starting a pot of soup on the stove and going about the rest of his evening.

A little more than a week passed, eventually leading into two. Much of the same continued day to day; Lou took care of the work he needed to do in his fields and every other night or two he spent some time in the stable with Grace. One morning Lou's alarm clock woke him up at the usual time and after rousing himself from bed he put a pot of coffee on the brewer and made his way into the bathroom to relieve himself like he did every morning. Mid-stream the farmer was hit with another strange feeling that something about him just didn't feel "right". As he stood there using the toilet his testicles felt like they were hanging down under him a little harder. Like what happened in the shower days earlier it wasn't overwhelming, just enough for Lou to realize something about his body felt off. When he was done he went back into the kitchen to check on the coffee pot and after standing around for a few minutes watching the brewer drip into the pot he rummaged through the junk drawer and retrieved the same ruler he'd measured himself with previously. He reached into his pants to stroke himself to full arousal and then placed the ruler next to his shaft. Part of him felt like what he was doing was crazy but as the ruler met the base of his crotch and he read the measurement his eyes widened a little bit. His cock, which just a while prior was just a hair over five and a half inches, was now just below six and a half.

Something was causing Lou's physique to change. The only thing different in his daily life of any note was the fact that he'd begun fooling around with his mare but that didn't make any sense to him at all. Lou's best guess was that perhaps the recent and sustained spike in his sexual activity was boosting the testosterone levels in his body and keeping them high which in turn was having this effect on him for the time being. Lou smiled to himself as he put the ruler back in the drawer. It's not like he had anyone he was trying to impress or anything but a bigger cock is something every guy asks for no matter how big they already are. Even if the near inch increase was just a temporary boost that would eventually go away the personal confidence that it brought was noticeable.

Nearly two months went by at Lou's farm. The temperature outside was finally starting to trend downward as the autumn months took over and winter loomed ahead. Despite this being the time of year when the leaves start to fall off of the trees there's always work to do on the farm, namely cleaning up all the fallen leaves for starters. Lou kept himself busy but always made time for Grace.

As the sun began to duck down under the horizon Lou entered the stable to be greeted by Grace who, as usual now, was already inside waiting for him. He greeted his mare and wrapped his arms around her before giving her a kiss, his fondness for her having grown to a place he once thought only a human woman could reach. In the weeks that had passed Lou had started making idle chit-chat with Grace not really expecting her to ever say anything back but believing that perhaps hearing him talk in a gentle voice would be soothing to her. Grace would occasionally nuzzle against Lou as he interacted with her, perhaps showing affection in her own equine way.

Lou made his way around the mare unbuttoning his pants as he walked. He pulled them down a bit with his underwear letting his shaft flop out in front of him. In the time that had passed Lou's manhood had continued to change. He was only half way erect but even in that state his shaft was already reaching over six inches and it only continued to grow and elongate as he stroked his length allowing it to pump full of blood. Fully erect it now reached just over nine inches and was thicker around as well; Lou didn't have a tailor's measuring tape though so he didn't know to what degree his cock was bigger around, just that it was much larger. His balls had also grown in size now filling out his sack nicely and hanging plump beneath his length. Despite being a sight to behold Lou hadn't told a single soul about his impressive tackle, he simply let the changes happening to him continue and watched them while measuring himself every once in a while. While looking himself over one night he noticed that about mid-way down his shaft there was something that felt like a light bump all the way around his length. It wasn't visible, but Lou could definitely feel it while masturbating. Something that was visibly different though was the head of his shaft; it looked a little flatter on its tip, the edge of the glans also becoming a little bit more pronounced.

As he stepped up behind the horse the farmer's cock flexed in anticipation, a thick bead of pre forming at its tip. Lou rubbed his shaft against Grace's folds spreading the fluid across them and causing the black outer skin of her womanhood to glisten in the low light. He pushed the head of his cock against her lips parting them and inviting himself inside. Despite his now porn star-sized cock Grace still felt quite loose to the farmer but he definitely was able to feel more of her slick inner flesh than before as she occasionally tightened up around him. Lou kept a steady pace as he palmed the mare's hindquarters and plunged into her with long and deliberate strokes.

Lou stirred a bit as he could feel himself getting ready to cum. His thrusts became a little harder as his climax neared and moments later the farmer moaned as he reached climax. His plump balls tightened up as a thick rush of seed erupted from his cock into the mare. Another followed, and several more. Lou had noticed that due to the size of his genitals his orgasms lasted noticeably longer because his balls had so much more essence to pump out. He'd tried to measure it one night while jerking off and after not being able to find a suitable thing to measure with he went with a shot glass which he nearly filled with one release.

With his climax waning Lou grinded his crotch against Grace to squeeze out the last few little jolts of pleasure before withdrawing himself. For a while now due to his growing length Lou's seed had stopped running down and out of Grace's vagina as he was long enough that his cum was released deep enough inside of her that it stayed there. He pulled his pants back up and lovingly embraced his mare before calling it a night and going to bed.

The season went by and with it Christmas and New Year's too. Lou made a trip across the state to visit family for Thanksgiving and catch up with everyone like he did every year and counted down the clock to the new year at his town's local bar. As was tradition he bought a round of beers for his hometown buddies and they rehashed their favorite memories of the times they'd spent together and everything that they'd weathered. It was Lou's favorite time of year, though this time he felt a little distant from everyone. There had been a major change in his life but it wasn't something he could talk about. His friends were all farmers themselves who also kept animals on their properties but he was completely in the dark about whether or not they knew one of their livestock the same way Lou knew Grace. He had no idea how to breach the topic, or if he even should. Lou kept those thoughts to himself and focused on the festivities.

Right in the middle of February came Valentine's Day, the day when all of the couples traditionally go out on slightly more lavish dates and exchange gifts. Year in and year out Lou mostly ignored the holiday as it never really applied to him however this year he did have someone to actually spend it with, just not the kind of partner most people would expect. Lou wore a light jacket as he walked into the stable, both his and Grace's breath appearing as a very light cloud of fog each time they exhaled. Rather than bring the horse something strange to her yet suitable for the occasion such as chocolate Lou carried with him a candied apple and fed the treat to Grace while stroking her neck and telling her she was loved.

Lou assumed his usual place behind her and reached down to undo his pants. As he partially disrobed the sizable bulge in his underwear became more apparent. The work clothes he wore did a decent job of hiding it but looking at the farmer in just his boxer briefs what they were covering was very visible. As Lou's manhood came into view any normal person would immediately notice it as something that shouldn't belong on a human. His cock was absolutely massive for a person, still in the process of becoming erect, but eventually becoming long enough to surpass the cheap ruler Lou had been using to measure it. By his best guess it was now fourteen inches long. His balls had grown to be a little bit bigger than a generously sized chicken egg and hung beneath him in a hefty thicker skinned sack. The lump that Lou had felt under his skin in his shaft developed into a much more prominent medial ring, and the head of his shaft had flattened out considerably.

His cock had gradually turned into one that looked like it belonged on a horse. The man realized around the turn of the calendar the shape his manhood was taking and what was actually happening to him. He didn't really celebrate or panic either way nor did he know if the changes happening to his body were some sort of blessing or punishment, divine or otherwise. Lou thought that perhaps if he stopped having sex with Grace that maybe his body would go back to normal, though he never really made any effort to find out. A significant part of him didn't even want to try.

As Lou stroked the opening of Grace's vagina the mare tightened up a few times before contracting her muscles in a manner that revealed her clitoris. Lou recognized this as her being in heat, something that had started several days prior. Grace's appetite for sexual pleasure ramped up considerably, there had already been a couple of nights where Lou bred her twice and managed to bring her to orgasm each time.

Lou positioned himself behind Grace holding his massive cock in one hand as he pushed himself against her lips. She was tighter now due to the winking but as she relaxed between muscle flexes Lou was able to slip the head of his shaft into her. He was so long now that he had to take a couple of steps once inside to get the rest of his length in too. The warmth of Grace's flesh contrasted with the cold February air felt absolutely heavenly to the farmer, like he could just melt inside of her. Until recently he'd never had sex with Grace while she was in estrus. It felt the same as usual overall, but every time she clenched her vaginal muscles to wink her entire canal tightened up around Lou's shaft and had the effect of nearly sucking him inside. Lou couldn't help but moan every time it happened, his toes curling slightly in his shoes as the head of his shaft was massaged by her folds.

In no time flat Lou was ready to blow. He pushed his length deep into Grace as he collapsed on top of her. Every pulse of his cock released a rope of cum greater in volume than an entire climax pre-transformation, and there were several of them. The farmer shuddered and pressed his hips up against the mare until he felt the last little bit of his seed spill into her. He pulled himself out, the head of his member having flared just like a stallion's post-orgasm. He tucked his semi-erect shaft back into his pants but didn't go very far. He needed a few minutes to come down from his high and in that time Grace would be ready for a second round, and possibly even a third if he was able to do it.

More than another year had passed. About 18, maybe 19 months. It was summer again. Lou rested inside of his farmhouse, sipping from a mug of coffee and leaning against a windowsill looking out at Grace in the field outside. She was joined by a young foal, about six months old. The foal looked just like Grace, same coat of shiny brown hair. Lou named her Charity. Grace's pregnancy came as a surprise to Lou, but in reality he knew how this must've happened. The farmer spent a lot of time with the two horses, especially Charity taking special care to show her affection and tell her how much he loved her. Part of him wondered if she even knew that he was her father or just some nice but funny-looking animal who fed and cleaned her.

The slow transformation of Lou's body stopped a few weeks after the Valentine's Day that was likely responsible for Charity's conception. For over a year the farmer's altered anatomy stayed the same, the last part of the change likely being his body changing the kinds of sex cells it produced. He realized he would never have a child with a human woman now, though that thought didn't weigh as heavily on him as it could've considering he was into his 50's. Lou realized in the past year and a half he hadn't brought anyone home from the bar either; Grace was always there for him just as he was for her. One night stands had become a thing of the past. Despite striking out and never being able to start a family of his own as Lou continued to look out the window he realized he still made it there in the end anyways.
