You wake up under a pile of straw in the back of an empty stall. The pleasant smell of equine sex fills your nostrils. The sound mating also gets your attention. Then you hear a human moan. Now your ears really perk as you dig yourself out.
Once you get to your hooves you find the young stallion and the riding mare just finishing up. He pulls out with a pop and drops to the ground. You chuckle and give the stallion back his stall, patting his flank as you move past. His taint is very strong.
What really gets your attention is the other stallion who is busy mounting a human female. This makes you smile as you watch the stallion pump her full of tainted semen. You can tell her insides have already changed as the horse is buried completely inside her. The beautiful long tail and chestnut fur she’s sporting is another indicator. It covers most of her lower body at this point. Hooves are just starting to form. Her skin is light. Her red human hair is just starting to change. She will make a beautiful addition to your growing herd.
Your cock slithers from it’s sheath thanks to all the pheromones in the air. You feel Donk squirming happily inside your ass. This is going to be fun.
You scritch the tainted stallion between his ears and speak to his mind. “Good job. She mine now.”
The stallion neighs and slowly pulls his cock out of the changing lady. She begs the horse not to stop. She is oblivious to your presence.
You bend over and extend a furry hand. “Hi there. What’s your name?”
Her nostrils flair as she catches your scent and looks up at you. “Gorgeous…” is all she can say.
You flash her your sexiest smile as you pull her up off her knees. Your eyes lock with hers. Her hand drifts down and strokes your cock, bringing it to full attention just below your nipples. Maybe the talking can wait till after the tainting.
You scoop her up effortlessly in your strong equine arms and kiss her with your half muzzle. She responds immediately with her tongue, french kissing you. Some convenient hay bales form a nice impromptu bed. You lay her down gently. He already black mare lips are coated, spread, and lubed. You slide your cock right in. She bucks and thrusts as inch after inch of equine cock penetrates her. In the end all two and a half feet fit comfortably inside her. The stallion did a wonderful job.
You pump and thrust into her, your equine ball sac smacking against he black equine lips. You drive the taint further into her. Her feet harden and become hooves as her legs lengthen and chestnut feathers grow over her ankles, Her tail lengthens as her human hair grows darker and longer. Her chestnut fur spreads upwards, covering her abs and mid-back. The fur stops just below her ample breasts which swell just a bit larger as they receive a light covering of short horse hair. Her nipples darken and lengthen into dark equine nipples 2 inches long. You tease them with your tongue as you fuck her, pumping and thrusting like the beast you are.
She moans and cries as she changes, finally letting out a lustful neigh as you cum hard inside her. You neigh as well as you pump her full of your tainted seed. You look into her eyes and see some hard years. You use your taint to melt them away. Back to 40, 35, 30, finally stopping her at a beautiful and youthful 25 years of age. Her smile is radiant now as you cum once more.
You stop the taint from changing her further. If she is the stable owner, she would be quite useful to have with her human knowledge and experience in tact. You doubt there will be an issue obtaining her willing service.
She is grinding against you like a mare in heat wanting more. You wicker and grant her request as you empty another load of tainted horse cum into her. She runs her hands through your long mane as she kisses you. Her long erect nipples pressed against your chest as you lay atop her thrusting..
She looks deep into your red eyes, “Where have you been all my life.”
You give a neighing laugh. Your huge cock still impaling her. “It was good for me too. Call me Equus. What is your name.”
“I am Amy, this is my ranch. I’m a Real Estate Agent. What are you?” She looks at you as if finally noticing how alien you appear.
“I won’t lie to you Amy. I’m a horse demon, a master of equine lust and sex.” You watch the corners of her sexy mouth turn up. You can see your taint and pheromones have totally corrupted her. “I want you to join me Amy. I can give you the money and power to enjoy all of the world’s pleasures, not to mention the most incredible sex you have ever experienced. If you work with me, we can win the world.”
Donk has been listening to all this, stimulating you. He hits that special spot causing you to whinny and shoot another load of tainted Equine cum into Amy. She orgasms in response and screams “Yes!”
You can’t help but smile. You kiss her passionately.
