A wealthy man stood as those transformed, he being a Welsh pony stallion. Aroused with wild passions, he knew his body to be young and virile, his libido that of an equine male. When he approached his first recently transformed young female and sniffing her rump, he enticed them both into a rage of animalistic lust.
Screaming whinnies of a conquest, as stallion stood nearly upright and with excellent aim used his taunt erection to poke at and penetrate the mare vulva. He marveled as did she, both feeling the lengthy inches of pony cock sink deep, sheath-deep, arousing both mare and stud to want more from their being then as animals.
A stallion feeling and enjoying regained youth, he was flagging his tail, and prancing a merry jig as his pelvic action made an old male feel again young. The sensation intensity he had never known when a man with a woman, he realized his control of self slipping, allowing the beast he became to control the man he was.
Shrill whinnies of young animals feeling passion, the ponies on the truck watched as waited for their sensual excursion into being brute beasts. All there with exception of the stallion stud kept their memories and understanding intact. Yet the doing of it just once with a stallion was never enough, as the bestial expressions tended to increase with the numbers or mating sessions. As much Madame rather expected, by the time the truck arrived to the farm, the mare in the trailer would be pregnant, and the stallion would be near insane from sensations and lust.
Somewhere down deep in the stallion mentality lay a human intellect wondering if being a stallion pony was what he preferred for his lifestyle, or did he want the luxuries of being a human?
