Your early morning feast is suddenly cut short, however, by your uncle as he walks through the back door which leads right into the dining room you were sitting at.
“Mornin, boy!” Your uncle boasts. “I was just about to wake you up. You teenagers sleep too much, you know that? So how are ya?” At this, you reply with a simple “fine”, although inside you are still deeply confused about your new attractions. “Well good,” your uncle says, “that means you can help me and Enrique clean out the stables again. Tell you what, those horses love shitting. But I guess you already knew that.” he says, chuckling.
“Actually, uncle, I don’t know. I’m not feeling 100% today.” you say, trying to avoid anything that involves those horses.
“Nonsense, c’mon, boy. You did it yesterday just fine.”
“Well, are the horses in the barn?” you ask.
“Well, not like it matters, but no, they’re in the field.”
“Well, I suppose.” You say, knowing that you have no other excuses.
“Good, let’s go.”
With that, you and your uncle go the barn where you are pleased to see that there weren’t any horses in the barn, just the smell of their shit. You greet Enrique, who seems to ignore you, acting much less friendlier than he was the day before. Your uncle leaves with Enrique to help Ben count the cattle, leaving you alone are a horse-shit-filled barn with a shovel. After a while of cleaning, you begin to realize that the heat and humidity is simply just too much for you, as you shirt is once again a wet garment sticking to your sweaty skin. Your newly formed muscular torso that you acquired hours ago feels the outside air. However, you are still just to dang hot so you also take of you shorts, leaving you with nothing but you socks, shoes, and Calvin Klein boxers on. It’s awkward, but you figure that your uncle and his workers should be spending a lot of time counting all of Norman’s cattle. You’ve noticed how your boxers, however, have become more like enlarged tight whites thanks to you r enlarged genitals and your newer, plumped and rounded butt. Even though you are practically nude, however, the heat still takes its toll on you. Norman said one of the horses kicked and broke the fan last night while they were being put away. Thanks to that, your body is trickled with sweat. You also noticed that you yourself stank from the sweat.
After a while, you were eventually done cleaning the horse shit, and you grabbed your clothes and went outside. You didn’t feel too weird walking to the house in your boxers considering that no one should be close to you, as the cattle were pretty far from the barn and the house. When you opened the door, however, you saw your worst enemy: one of your uncle’s chestnut mares.
You drop your clothes and try to look away, but you can’t. To you, that smelly beast was beautiful, more so than any female human you had ever seen. Your penis became erect almost instantly, but since in was in your now tight boxers, it was just a long, hard lump. Almost as if you were in a trance, you walk slowly up to the mare, and stroke her back with your hand. Her fur is so wet with sweat that your hand becomes drenched the moment you touch it. You look at her ass, that beautiful, large, and firm ass. You then start licking her fur. The taste of her salty, smelly sweat gives you an ecstasy of pleasure. You rub your face in her hide, your tongue scraping against her wet body. The mare seems not to mind this, even when you start liking her muzzle and eventually kissing her rubbery horse lips, your tongue slopping against them while yours and her’s saliva trickles down your sculpted body or onto hers. You then go around are start dry-humping the side of her leg, drenching your boxers with her sweet sweat. You hump and hump and hump until you cum the biggest load you have ever had, at this point wishing you had a stool so you could do the same into her vagina. Eventually you go around to her rear. You kiss and lick each of her butt cheeks like a true romantic. Then you push her tail away and do the same to her soaking wet sex.
It is at this moment that you realize what you are doing. You back off the mare in horror at what you had just done. You feel and see the mare’s sweat and saliva all over your body, and your boxers which are covered in your own cum. You run back to house in disgust, quickly grabbing your clothes along the way. Upon entering, you rush into the bathroom and try to puke out all the horse sweat you had swallowed. You don’t puke, but you do notice something else. The bulge in your crotch had gotten bigger.
You take off you ruined and cum-infested Calvin Kleins to see you penis, or what used to be your penis. Now, it looks more like an uncircumcised hose. Your dick was once again longer, it was flaccid yet it easily surpassed your belly button, and it almost hung down to your knees. Worst of all, its end was flat and it was extremely darker in color, as were your balls which had swelled to the size of grapefruits and weighed your crotch down considerably. Besides this, you also noticed how much taller you are. Your head could almost scrape against the top of the door frames. Everything else about you just seemed… bigger. Your torso was bigger, your hips were wider, and your thighs were a lot bigger, so was your ass. Despite your ass’s huge size, however, it remained firm. Your feet were also a lot longer, the comfort causing you to remove your now extremely tight shoes and socks. You also noticed that once your shoes were off, your feet got longer before your very eyes, and your body automatically made you stand on your tip toes. You were also given an extra mass of muscle. You looked at you legs further, and realized that they looked like the hind legs of a horse. This realization made you scream, but instead of a scream your vocal chords let out a loud horse’s whinny. Horrified you look at the bathroom mirror, and see that your ears are pointed and more towards the top of your head, and that your hair was black. But most terrible of all the changes was your face; your nose and mouth had combined and formed a miniature muzzle that stuck out about four inches. It came complete with buck teeth and a long tongue. In the middle of your panic, you hear a knock on the bathroom door.
