As the beautiful black stallion circles around me and the mare, I was struck by a intense admiration for his sleek equine form. My breath growing deep and ragged as he moves in closer to me, strangely I can smell his rich musky scent heavy in the air. I move out of his way as he draws closer to the mare, eager and excited he prances around whinnying in sexual excitement. His erection was magnificent swaying and flexing under his big round belly, already it was drooling silver equine pre-cum. Moving over I prop my cellphone up on a shelf so that it can catch all the action.
"Good god..." I said in shock and desire, as the mare danced sideways and whinnied loudly. The big black Stud moved sideways with her and then laid his head along side her rump and pushed her back. She shifted her weight as though she was going to kick, but he didn't give her time as he reared up and mounted her. She stepped forwards, however he followed along behind her until she was cornered. All the while his huge erection was stabbing wildly trying to find her hot wet rut tunnel. As the mare stopped, his huge fucker pushed out around the side of her big round hip. I found myself stepping forwards, wrapping my hands around that big throbbing fuck muscle. I just couldn't resist for some odd reason, as I fondled it I leaned forwards and licked the massive flare. The black stallion nickered loudly, sounding almost like chuckling as he watched me kiss and lick his fucker for a moment before guiding him into the waiting mare.
I heard her breath go out of her sharply and then she made a coughing squeal, as his big dick found its mark and rammed deep into her. "Damn girl that must feel really good." I breathed stepping back as I watched him go to work bucking and fucking his colt maker in and out of that dripping sex. The two of the squealing loudly, the mare pushing back into him as the mighty stallion rammed himself in and out of her. Suddenly that massive fucker slipped out and thrust around the side of her rump again. Quickly I stepped in and grasp it, shocked as I took the whole flare into my mouth. Taste her mare fluids and his salty pre-cum on my tongue as I loved on that magnificent fucker a few moments before putting it back in her. My face blushing so hard it felt like I was on fire, as he nickered at me once again. This time I was sure I hear laughter in that equine sound, my body felt odd like my clothing was to tight for it.
"Its so hot in here." I said quickly stripping off my shirt and then slipped my pants and boxers off. I heard him grunt loudly and the mare squealed again. That was it, I knew it was all over but the shouting so to speak. The were stallion shuffled back and came down off the mare, the head of his shiny black dick brushing the deep straw for a moment, before it slowly began to lift up stiffly. "Wait... wha... whats going on?" I moan confused, as roan red hairs started to cover my arms and legs. Suddenly intense pain racks my body and I could hear snapping sounds, and saw my toes fusing into hooves. "Oh fuck what... whats..." I hear myself moaning, even as I looked down at my cock, which was steadily shrinking... grown visibly smaller and smaller. Until is disappeared completely withing my body, even as my testicles drew up and flattened. Suddenly melting into a bit pink teardrop shaped mare sex, my mouth dropped open in shock. "No wait..." I dropped to all fours in that moment as my hands turned hoof like, and my body grew larger by the second.
My face swelled and stretched into a horse's muzzle as my body gained mass and size, and a long flowing tail sprouted.
The whole time my mare Midnight stood watching and pawing the ground with one first hoof, and seemed to be rather pleased to see what was happening. She nickered and although I knew it was nickering it sounded like laughter to me, even as she tossed her head. And then I heard him behind me, felt his breath as he sniffed my rump. 'I knew you'd be my mare as soon as I saw you.' I looked back over my shoulder just in time to see the big black stallion rear up and throw his front legs around my body. I jumped and a breath went out of my new body sharply making a odd coughing squeal, as his big dick found its mark and rammed deep into my body!
