You knew the delight felt when having sex an almost mare. Unknown to you or her as how you were infected as it happened. You genitals did change first, as other changes came later, but all seemed to come from having enjoyed sex with Jessica. One thing was obvious to both her and you, that the sure feeling that when Jessica was Jessie the mare, she knew more of how to make a man wish for change to his form.
Indeed, the memory of your last time of sexual pleasure stood vivid still in a mind tweaked by masculine pleasures.
Jessica stood there looking at the emergency kit taken from the glove box and setting then on the coffee table in the cottage. She looks angrily at you, not sure maybe if you had the thought to use it on her, or on you. Long minutes of silence pass before the question was posed. "What is your plan for that kit?" Jessica asked.
You sighed, as recalled the sensations of how she when almost a mare, had strong vulva lips and a flexing vagina what working together held so tightly that stiffly engorged cock. The want was to again feel as impaled by her vagina.
She being younger than you, brings on the memories of a middle aged man struggling with his weakened sexual ability and bought male enhancement pills. Those pills you tried for six months what did nothing for growth and were meager a help to gain an erection. Yet she, Jessica when tainted with the infecting Reformation flux serum offered you her body to quell the need for sex; you gained a penis growth spurt. You relished the feelings of having an animalistic size cock, as it grew to equal that of the stallion pony.
You dropped your pants there before Jessica to prove to her as remind her to what new greatness grew there between your legs. You felt with shaking fingers at the outer layers of your sheath. Jessica stepped then forward, she coming very close and with her hands she did arouse your cock. You stood there elated, relishing the slow sensation as your cock rises from where it sleeps. The dry wrinkled skin grows slowly taunt, the cock body swelling, soon to length to sixteen inches when in full erect state.
Jessica is not without her fondness for the blunt, uncircumcised end to your cock. As it bloats and the head flattens taunt, the extra sensual banded ring around the outside of the head she messages with her index finger. Her other hand is busily stroking the length of your cock, as she and you were testing the waves of mutual desires.
"Oh, oh Jessica, the feelings from this, from your touch, why I would wish for this and never again be worthy of being circumcised. I want to be a real stallion, animal, beast, it does not matter the dull lifestyle, but come the need of me being a stallion at stud, makes the degradation seem minimal. I would love you more than an other mare given to me for to mate, breed and impregnate. I know a great want for to hump horse mares and/or especially one beloved pony mare." You will forever recall that rant of what you felt for her and wished to feel again and again.
She did with you moaned together from the present sensations, as she and you remembered the nights and days well when each felt the tight hold on his cock slacken and grow tight again. You became a changed man from the sensual contact with an almost mare body of sweet Jessica. You nearly smiled with the memory of how she after you mated with her she did walk about wandering in in circles, shaking her head at the thoughts of what she should have felt a sense of personal disgust. Jessica shed then her clothes with a plan arouse her lover-stud and coax him to lie with her on the cabin bed.
Movement and a lack of sensuality for a few moments had your cock softening to hanging flaccid. As Jessica acting more again like a willing mare, she naked lying with legs spread, were furry still, her thighs like flanks, and buttocks very much similar to those of a pony mare, as her tail wiggled. Her vagina was still poised to her rear as she had an udder and two well aroused teats all puckered with her anticipations. Those were again a minutes of extreme excitement brought on by your personal need, while she sought to feel her own style of contentment.
You returned to her, as strode your walking to attend to her want or need. You were then as oblivious to the possible danger from acting alluring. Your eyes were on Jessica and pleasing your sense of passion, or did until you noticed the bedside table and near to the small lamp lay the emergency kit, it opened, with a vial and syringe read for some probable use.
Your being a mature man though physically tainted by the Park's Reformation Flux serum through having had vaginal sex with an almost pony mare, seeing the vial setting out from its socket in the kit made you point at it and grunt. You acted as mister tough guy, having seen her plan, you were ready to walk away.
Jessica moaned as she sat up and swung her furred legs off the side of the bed. You felt a sense of anger about the kit, maybe similar the same attitude she had when she took note that you had taken the kit from the truck and had it inside the cottage. As unsure of your desires then, you walked up to your horny loving mare, as she wished to get mated, you reached a friendly hand to smoothing, pet your hand down the withers, over her back and curve it round lovely rump.
Suddenly you felt that sense of loving warmth, your fingertips feeling of just how wet was her vulva. You turned quickly, not giving a thought about your male member being flaccid but hanging still stout from the sheath. Your feelings for her sparked that fast turning around, as made your meaty cock to fling, as it hit her up-aside her head. The harsh slapping whack of your stiffening cock made Jessica yelp, as did it cause your bladder to release, as both she and you saw a sudden stream of greenish yellow urine stream past her face and fall to make a puddle on a small throw-rug.
You stood there horrified by the sight, the feel, and knowledge that your urine likened to the bodily fluids in Jessica had the properties to infect a person, or reinfect someone for a second time. Unrealized then by you as something more happened to you then to consider as possible. You being infected by Jessica, you never did drink the antidote, the vaginal fluids had infected you, were changing you, creating a Connemara pony stallion. Until then only your genitals had seen great changes, but the infection was tracing through the gut, as moving from one organ to the next. The bladder unknowingly was changing, getting larger. Your stream of urine was both a fat stream as it did shoot the distance across the room to the rug. Jessica laughed though was surprised at the distance your urine did carry to its place to puddle.
Embarrassed, your mouth failed to work as expected and instead of exclaiming a sense of apology, you spoke a soft sounding whiny!
Jessica stopped laughing when she heard you whiny. She stood up and taking a two handed grip of your male member, she walked her fingers along the length to begin her messaging of your much bigger balls.
"Be calm, such sounds and more changes are still to come, you should drink the antidote, or if you want to feel as become a pony stallion, there it the vial and the syringe to make use to your wish." Jessica said, she offering to let you go all the way, or to help stop what would claim you physically, as permanently.
You knew that in the next few days your human body would contort harshly, there would be pain, until horny, you shall begin walking the earth as a equine animal. As Jessica urged you to lie with her on the cabin bed, your mind was considering the scheme, whether her plan or yours, was this a sentencing to live as a pony stallion, you owned by Jessica, or she selling you into a sexual style of slavery.
Thoughts faded as to making love to Jessica, as you lie there thinking, pondering if your wish was to satisfy carnal lusts. It seemed clear that Jessica was willing to help you go all the way, see you do the changing, drawn to breed and not love a female, but find your ultimate desire as when humped over the hairy rump of a nervous mare. As Jessica snuggled closer, she feeling, messaging, coaxing, beckoning with her investigating mindset, she would document how a man would change as wish to become an animal, living beastly, a stud to breed with his chosen kind.
The unholy as rank sensual sensations to relish living life standing on all fours, mating with and not loving any mares. To stand as humped and thrusting, accepting being an animal as wholly proper. The meeting of equine style life head-on in a stallion pony form, while able still to remember a lost humanity. All this and so much more as unrealized coming from the love of having a big cock and huge balls. Your lovely long cock as so enjoyed, but considering the uncertainness of a future being as an animal, as property owned, caused a sense of apprehension for what Jessica seemed to want for you to know firsthand.
