I stood stock still as I acclimated with the new body, the entire experience was surreal and I didn’t even want to believe my new reality, probably the result of a bad dream or a strange chemical.
The new sensation thought told me a very different thing, my flat tongue moved inside the mouth to feel the new herbivore teeth and the black tail behind me swished from side to side experimentally, there was no doubt that I was not human anymore, only a healthy dose of panic and disbelief.
For the better or worse I was a normal mare in the stable, and I didn’t have an escape route ready, I closed the door when I entered to steal the filly beside me, now looking at me with surprise and a hint of pity with a disturbingly human range of emotions.
My objective was to escape from this trap as fast as possible and pray that the transformation will reverse on its own, I trotted for the door only to spot a new horse moved before me and barred my path, from the smell I recognized him as the stud of the stall.
The stud near me was clearly interested and excited to see a new filly, it would have been normal if the horse in question wasn’t you ‘Sorry buddy, not interested, I’m not an animal’
I snorted menacingly to make him understand to back off after I tried to move around him without success, the infuriating stallion repeatedly strutted before me exploiting my slow and unsure gait to show off time and time again his erect shaft, to my dread the interloper was really horny and drops of pre-cum started to fall on the floor.
‘Go away, move to the other mare if you are so aroused, I’m off limits’ My hooves pawed the floor to show him my unwillingness as my tail shifted nervously, the stupid horse instead of backing off seemed amused by this defiant attitude and snorted mockingly, but after a tense stare-off he lost interest in me and trotted to nuzzle the other bewildered mare.
This was my chance to examine the door for the way to open it or a weak spot, the gate had pretty solid wood while the lock was inoperable by horses, so… I stiffened in shock as a nose sniffed my vagina, trickling it with the air exhaled and inhaled through his nostril, before my animal instincts took over and I wiggled my rump in a lust haze, prompting the stallion to kiss gently my moistening folds.
Using my conflicting instincts Harry leveraged his position by landing heavily on my back and nibbling my right ear invitingly, while his stiff rod poked my leg in an attempt to line it with my slit.
The shaft finally reached the mound and the stallion prepared himself to plunge his cock inside by starting to part the folds with its head, lubricating his member with my gushing fluids, in the exact same moment I realized the danger and started to put up resistance, kicking and neighing.
It was too late: with a sudden thrust his cock slid effortlessly inside and filled my wet vagina before he started to pound forcefully with unmatched lust, with wet slaps the stud claimed the struggling mare as his own, a new addiction to the ever growing herd, whose resistance weakened with every thrust and started to enjoy the bestial mating more and more.
