A vague bit of the black boiling cloud had lingered still, as it swooped around James from his waist, moving ever lower along his legs toward his feet.
"Hey there you, and what just might you be doing to my new companion," Kayla asked, or maybe she yelled, wanting to be in total control of how James would be seen by her father.
Slowly but methodically, the black devil affected how James was able to stand, walk, and if needed, run. Kayla watched as what were human thighs covered by pony hid and fur, began to take on the contours of hind thighs, similar to those of a pony. The devil spun down and along the changing legs of James, conforming bones, joints, tendons, and muscles, he raised the heels of both feet into the position for being hind hocks. As then the human feet rose when the heels became hocks, the devil changing the bone structure to make hind feet of an equine, as metacarpals became fetlock joints, and five toes quickly merged to form two single toes, solid pony size hoofs.
The changes brought James to then stand taller than he had when next to Kayla.
Seemingly delighted by how his legs and feet had changed, James began prancing in a wide circle. His sense of glee fostered him to whinny aloud, his black tail swishing as he pranced, and elated, he tried to coax Kayla to dance-prance with him.
"You are done there devil, now leave my friend to me and my plans as how best to make use of him," Kayla said, as said harshly at the dominate devil.
"As well so might I know what sordid plans you want for him to do, as entertain you, make you laugh at making him your fool." The ghostly black devil so spoke to Kayla. "I am not finished with this fellow, as much he appreciates the shape and configuration of his changed genitals, it is he who has now a great desire for sharing his enhanced gifts with you his mistress, and a witch."
"Share, share what, he is my companion, not my lover!" Kayla exclaimed boldly.
"As much you wished and schemed for him to accept what you did as are still making of him, in his mind he thinks of you as a beautiful woman he would adore lie with, whether on top, or from behind." As that told by the devil to Kayla, he took his time to leave, laughing manically as he faded back toward hell.
"Like hell," Kayla said, as James feeling elated and still prance-dancing, he came up close behind her, and holding his pony cock with one hand, he aimed it at where if Kayla were a mare, she might delight feeling her body as penetrated.
"Bug off," Kayla turned and yelled at a playful James, his black cock standing out of its sheath, was fully erect, and beginning to leaking some pre. The slapping of what James stood offing caused the drips of pre to take to the breeze, splattering in all directions, as some caught Kayla as unaware.
