Though Mitch knew and continued to compile a list of what he as a human enjoyed doing, the taunting suggestions said by Mister Perth were twisting a young mind to think only of lust, want, and sensation.
Mitch wandered into stall used for temporary storage of hay bales before they were broken and fed to horses in their stalls. The mass of imposing bestial feeling pulsing in his groin was enough to invoke him to masturbate while Mr. Perth watched. Though Mitch had bred the horny mare his balls might of had some human semen remaining, as just a little was enough to complicate any form of transformal magic.
Mitch had stripped his body as naked and messaging his donkey cock began the exchange of human for donkey animal body parts, skin, hair, and internal organs. Feeling some minor pains and a general sensation of discomfort everywhere around him, Mitch began to appreciate how his masturbated big cock would shot its load more than four feet across the barn floor.
Looking over at Mr. Perth, Mitch smiled and mouthed at the man the words of "Thank You."
Mister Perth remembered well when he was a horse and if there were no mares in the pasture he would try and ease his sensual agony by using equine libido and masturbating, bumping a weighty cock at a furry belly.
Feeling his body mas increasing, Mitch stood up from where he had sat for two hours ejaculating his cock. He felt the exit pain as his tailbone sprouted the stub end to his soon donkey tail. He relished the feel of the quick growth of his tail, the whisking of it across his fuzzy buttocks, and then later, after his human anus became the puckered donut of an equine, the toughing increased his sensual delights.
Mister Perth walked out of the barn to look for another pony mare likely as willing to let a crude donkey bastard breed with her.
Mitch was leaning with very furred arms changing to become his forelegs, as he gawked down at fingers melding, merging, as in just fifteen minute they became as donkey hoofs. He saw he had the forelegs and hoofs of a donkey, Mitch raised his head and face heavenward and bray aloud his panicked feeling of remorse for having asked to become a donkey and not some handsome, gallant standing stallion horse, that Kelly in the near future might want to ride.
"Feeling some concerns there lad, then come here and try your cock in this horny Welsh mare!" Mr. Perth offered to Mitch, and Mitch went to the mare and without so much as to sniff or give her vulva a lick, he thrust in sheath deep and started to rut the mare. A half hour later and Mitch was looking more like a donkey than when he began rutting the elderly mare.
A foreseeing Mister Perth remembered well the pranks done to him when he was a stallion, as the real farm owner there would wait, and when Jacob the stud was about to withdraw from a mare, the crafty farmer would hold a cotton cloth coated in mare vaginal slime and force the stallion into a second round of breading the mare. He waited for Mitch to become cock flaccid, as then he covered the donkey muzzle with a cloth soaking of vaginal slime, reinforcing the half donkey animal to begin anew his onslaught of breeding the then calm as elderly a mare.
The sun had set in the west when Mitch finally finished mating his fourth mare of the wild first day being a donkey jack stud. He brayed wildly, as walked back to his stall leaving his expanded cock to swing and sway, it slapping hard at the outsides of his broad furry flanks.
Mitch had some time to drink from his water bucket and sniff at the ration of feed grain, it left for him to munch when he felt ready. Time enough for him to turn in circles to look at what all had changed. What Mitch saw was the equal to a two year old male donkey Jack. As he had watched his arms become forelegs, his hind jack type legs did their conforming while he was cock rutting the mares brought to him by Mr. Perth.
The transformation of a late teenager human into a young age donkey stud left Mitch struggling to feel the exchange was better by him becoming a common farm animal. In fact he was questioning his sex based decision to ask for being a donkey. He was a dark brown mostly, with a mealy black and white muzzle, a white furred chest and belly. His skin was thick as it was black. His ears were long and he could twitch, turn, and shake them to please his present state of mind.
One sad portion of his changing species was of the loss of seeing the world in beautiful color. Mitch had a gray-scale form of vision, like watching black and white television, but something very permanent.
Hoofs, long lanky legs, a bony tail with a coarse haired switch was not any more sensual than his having a cow tail. His ears, round big eyes, nostrils and thick lipped muzzle, all this and then the flies liking the way his body tasted of sweat, salt, and where and in what he might lie down as roll over.
It became a long night of many mournful brayed cries of a lonely youth dealing with the lifestyle of a barn animal.
That same night was no better for young teenage Kelly, she knowing her parents were deposed magically, made into farm animals, and the animals had become the forms of her parents. Added to her family demise, her friend and lover looked to a beastly man for input how best to live his life and future. Mitch she heard braying his fears through the night, until in the wee hours of the early morning she went to him, she in her nightgown and having her period, Kelly wanted to talk with Mitch.
