Although it was early in the morning, John had a thought, he had an urge, and without asking of Herman or offering an answer as to what he thought, John got up off his bed, he getting dressed, then walked out of the house. An evil desire was growing then in John, and although he felt it, he felt that urge to feel a sense of greatness.
John walked, as he took to looking around and feeling that urge, he walked to the farm of Mr. Centros and then into the barn. The barn felt oddly more like home than did the house where he lived with his parents. As John took from his pocket the silver chain and the locket attached, asked the locket to give him the required changes of bodily form to allow then him the ability to mount a horse mare, and let him then to mate, breed, have sex like a stallion for an hour.
As he stood he felt the chain warm and his body fill out. John then stripped off his clothing and laid them in a pile to one side. Looking down, he watched as his boyish size penis bloomed into a cock equal to the lusty task needed by a stallion. As his toes merged quickly to form hooves, his legs sprouted hair and jet black skin. Legs grew longer and broadened. A tail sprouted with a sharp pain. His thighs and butt grew to needed size and the new hair spread upward, but stopped just short of his pecks.
As several of the housed mares offered him their glorious rumps, he stood there becoming aroused, seeing vulva lips winking, tails raised, and offers made. John felt a rage of sexual want like nothing he had felt for any girl. He watching, knew as his horse cock got really hard, that he was ready to enjoy.
John tried walking, his strides being rather unsteady, but he approached the first as closest mare, he felt of her furry rump, as positioned his cock for entry. John leaned toward the mare and with his left hand he did aim, as let his cock plunge deep into the horny mare. John began to enjoy his partially changed as equine enhanced form, feeling as doing sex from a horse style and perspective.
As he finished and stepped back he began to change back to his boyish self, John watched as his horse cock dribbled some creamy semen onto the barn floor. In his urged rush he had put the silver chain and medallion locket over his head and set then about his neck.
"Gee whiz but that was fun," John said, "Now I know about what that guy felt when he was a horse cock. Such feelings feel neat, I like being a stud stallion, and would by the desire of my guardian Angel, give than asshole of a guy his second life again, as I wish him to leave from being an asshole to live as a stallion sheath, cock, and scrotum. Yea, I would wish he had eyes placed into the upper folds of the horse's sheath, his mouth with a tongue as the piss-hole a mouth. He could taste then the semen and the urine, spewed out the cock, as all the while knowing of what he is, and how he shall remain, he then permanently being the male genitals of like me and mine as I am being akin to a stallion horse."
John turned and strode to the next stall where another mare stood waiting, she more horny than was the first mare he mated.
"Oh how I want to feel this mare like I was a real horse with a live cock to arouse me more...!" John said, as felt then the warmth of power around his neck causing a response to his verbal wistful mutterings.
