The day progressed slowly for everyone involved. Your roommate was clearly distressed by her new condition, the more time passed the more she stole what passed for furtive glances of you, specifically the special something poking your belly.
Already the oversensitive slit soaked her hindquarters with juices, filling the room with the fumes of her arousal. More than one time you saw the filly make the first step to reach you but every time she managed to rein the instincts with pure willpower. Even your own will faltered more than once, you started to sniff the result of her arousal while daydreaming about a good rutting, a stallion and his mate locked in a cycle of deep thrust and loving neighs.
You managed to resist the entire day but as you lie down to rest you ponder the fact that an escape avenue to the forest must be found immediately, or the stables will remain your home forever!
Not even your dreams allow respite, the first dreams in the new body were bout you as a normal human, while that night they were supplanted by grasslands and free herds. The plain is your home, the herd your family, you see the familiar visage of your parents, a couple of strong mustang that passed their brown hides to you, and your younger sister, an adorable and playful dapple filly. And how could you forget the new addition to the family, your beautiful mate, the roan mare approach you with an endearing gait and a raised tail to state her willingness to expand the family now that she entered season. Her tongue stimulates your member with slow and sensual movements…
You awake to the sound of chirping birds in the familiar stall, but before you can stretch or drink something wet and long brush against the length of your stiff cock. You turn to behold one of your worst fear, the filly resisted her urges before but now she has clearly snapped, and jumped consequently the first stallion. From all the clues she lapped your shaft for some time, and probably spurred your dreams too.
The situation got out of hand quickly when the mare stopped the ministration to nuzzle you, then exploited your indecision by turning around and with a coquettish neigh lifted her tail, presenting herself to the nearest stud. All the other thoughts stopped dead when her swollen labia winked at you, you were never more aware than in this moment of the erect cock poking your underbelly and the rising warmth in the stall.
A step was the only thing splitting the two of you, instinctively you leaned down until your nose touched her under the tail and breathed deeply when you felt her folds twitch again with need. She stealthy and slowly pushed back her rump, causing your muzzle to part slightly her folds when you recoiled with a frightened whinny, backing from the temptress slowly.
‘What was that? I am not a beast, for a second I thought my family always consisted of horses and my mind was entirely gone, I almost lost myself to the false memories! I must extend my discipline if I want to run’ The mare was obviously unhappy with your choice, she stomped and huffed annoyed at the rejection even as you stared at her dripping juices ‘Yeah, d-discipline’
The horny mare gave you a look of desire with barely any hint of rightful shame as she approached again with a swaying gait, highlighting her commitment to your seduction. You were trapped, the stall did not provide safe zones from this crazed mare, and her behavior made you feel as a hunted animal with his back to a literal wall.
This time the filly chose a more subtle approach, she licked your muzzle clean of her juices before shoving her tongue in your mouth for a rough kiss, interlocking both the appendages together. You were starting to enjoy the experience when she backed away and circled around you with a predatory and lascivious gaze focused mostly on the tool between your legs.
‘What is her problem, doesn’t she understand that we will stay like this forever if we mate?’ Once again the mare pounced with her muzzle on your shaft, without giving you time to react.
‘Oh god!’ The filly whip her tail left and right excitedly as you don’t oppose the ministration anymore and instead start to instinctively thrust forward with mounting lust. Memories of your previous girlfriends in provocative poses assault your mind as the mare continues undeterred, over time you don’t even notice as your fantasies about attractive girls shift more and more toward several mares in heat lined with raised tails, all suspiciously in the likeness of your roommate, as you get close to the first equine orgasm of your life.
If she could the filly would be grinning at her success, the stallion is ready to claim her and he needs only a little push, that she is graciously willing to give. She stops her ministration shortly after, hear the frustrated snort of a stallion in the brink of orgasm but unable to do anything, and draw attention to her puffy folds, slick with juices and more than ready for him.
This time Derrick doesn’t hesitate and his hooves help him as he climbs on top of the mare and prepares like a true horse to mate with her. He lines his cock to the awaiting vagina and feels the mare under him shudder in anticipation as the erect shaft comes into contact with her lips.
You stop abruptly before the plunge when a sense of rising dread surfaces, but as soon as you center yourself for a better judgement the pheromones of the female in heat ensnare you again with no effort. There is still something that is screaming inside you to step back and run from the temptress, but the conflict between carnal desires and an elusive and frankly forgotten danger is heavily leaning to the side of debauchery.
Decision made the stallion nibbles affectionately the mane of the mare and with a thrust claims her, joining his hip with hers with a meaty slap. He grunts as his cock slide in and out of her as they undertake the effort together, the filly following dutifully the pace dictated by the stallion with a lustful and eager disposition.
You reach your threshold point when the mare throw back her head for a loud whinny as her canal clench your shaft, spilling juices all over your back legs and hooves, and in the next moment your shaft throb and release several burst of semen inside your lover. You preen for a job well done while you pant exhausted, even if you have the niggling feeling that something is seriously wrong with your body…
The mare seems satisfied as you land on all four again with a loud thud and brush her side with yours, before she trot playfully near the through and present again her wet folds for another round, blinking innocently at you. She is ravenous! You nicker amusedly and join her without a second thought, after all you are her stallion, aren’t you?
