It was an easy heist, my only job was to reach the stables, distract the attendants and spirit away one of the young mares with no one the wiser.
How wrong I was…
The robbery was commissioned by a rich landowner, he offered a little treasure for a seemingly low risk job. He was a bit shady, but his love and passion for horses was renowned around my home town. Apparently he tried to buy an Arabian stallion from the zoo that caught his eye, but was turned away almost immediately with empty hands, but not before admiring the impressive specimens in their stable.
He wanted one of their horses, and he wanted it yesterday.
Slipping under the radar was rather easy, I left the trailer along the truck in a secluded alley and only had to wait and the attendant left the stable, giving me full access to the building now that the other workers had other chores.
The girl would be occupied for a short while so I searched for the new mare that caught my interest, when the attendant led her inside, the animal was sleek, build for speed with wide hips, a long flowing black mane and a beige fur.
She was exactly the specimen I required to appease the landowner, so I approached the mare quietly and grabbed her reins, herding her outside to the trailer, and then collect my dues.
This was the point where everything started to go wrong, the young mare struggled and whinnied her disapproval, in haste I pulled harder but the mare stubbornly stood still.
The horse was new to the stables and you cursed your luck when she didn’t obey, a clear sign that you should have chosen a more behaved animal with ample training. The mare surprised me again with a light nip on my arm, with an angry glare I gave up on her when suddenly a jolt get thought my entire body, followed by a feeling of intense warmth.
Beads of sweat formed on my forehead as a rapid change overtook my arm, light grey fur spread at an alarming rate on all my body as a swishing tail grew from my backbone and my black hair became a mane, my pants were the first victims along the shirt to this strange transformation since my hips inflated, so I had a first view of my shaft when a pair of leathery black folds opened up at the base of my tool.
I watched impotent with a grimace as my proud member disappeared inside my body inch by inch with a wet noise, leaving at last only an oversized slit, while my body changed all the way to resemble that of a Lipizzaner mare with frightening speed.
I was so shocked that I didn’t even notice a stall door opening behind me, a stallion named Harry had eyes only for my body and his erect member was more than willing to introduce the joy of mating to the new inexperienced mare.
