Your lustfull bellow fades and you look back into the mirror. The thick curving horns of a water buffalo crown your head. Your head is likewise bovine, and could proably pass for a minotaur's, your teeth can't however as you notice you have sharp teeth and fangs like you'd expect in a dog. Looking down your draft horse cock is still erect with nowhere to go. Still consumed with lust you consider your hands, your fingers end in black talons but your palms have large black pads, you have the paws of a great wolf with equally useless dewclaws.
You sense movement behind the mirror and wonder what else can happen to you, you hear voices.
"We followed the specifications exactly, why shouldn't this demon be perfectly acceptable".
"Our people at the carnival are overjoyed with the pictures we faxed then, we just need to make sure it can breed."
"I think you don't trust our cause enough, he followed the tome exactly, testing him now only shows a lack of fate".
"My faith has already been recieved, besides we already have the 'test subject' and our stud has already been prepped for servicing".
After a few moments the mirror rolls away to show a naked girl on a hospital examination table. She is understandably shocked to see you and screams, though with your senses you can tell she dosen't expect help from the doctors who put her in this situation.
A voice comes over the microphone, "don't worry, this is what you signed up for, he'll just inject something into you, just relax and try to enjoy it."
Animal lust comes over you even harder and you lick her pussy. The girl smells like smoke, probably a runaway or druggie looking to have gotten a fix. She starts carressing your horns, giving in to her own lustful thoughts and desires. You don't know if she's been drugged or under some kind of spell, but your only concerned with that she's giving herself.
You drive her flat onto the table with your water buffalo's head, her hands still grasping your horns. You stand your paws on the table, holding her slender body in between them, your dewclaws pressing into her skin. With nearly the same movement your goat hooves dent the ground as your draft horse loins shoot your wet cock into her. You barely hear her screams over your grunts. You drive with enough force to break her legs, but the hospital table prevents you from meeting her full on. Her grip on your horns tightens and her nether regions loosen up, allowing you to penetrate further.
Unable to hold back you move your entire bulk onto the examination table, causing it to buckle under your weight. Your entire equine cock easily pounding in and out of her slightly elongated body, spewing your seed throughout her. You below again, but this time as an avatar to the god of lust, drawing out your cock for the last time leaving a pool of steaming semen.
You crawl off the girl, the smashed table no more than a foot off the ground. Part of you is surprised to see her still breathing. Getting up to look for some food you notice that her mid section is two feet longer thatn it should be, and her belly has four small teats bellow her belly button, the unmistakable beginnings of an utter. You follow the odor of raw meat and water to the metal basin you were just standing in and gourge yourself as the mirror rolls back into place. Your animal satisfied by sex you find it easy to concentrate on what is said while feeding.
"What was that, what did it do to me?!"
"Don't you worry your sweet little head, you'll be a mommy soon so try not to stress yourself out, it's not good for the baby demon spawn. Stop crying, you'll be happy enough by the time you're ready to calf, by then your udder will be producing enough to keep it healthy, and the rest of you will be developed enough to accept a proper mounting."
The mirror moves toward you and the opposite wall opens to reveal the inside of a cargo truck. You're now officially ready to join the carnival...
