Circe cocked her head in obvious amusement. "A smart horse, then? Probably the best choice for one who wants to be a beast." she moved in front of him and held out her hands. "Dop your muzzle for me to hold."
Ryan did as he was asked, letting the strong, hairy chin settle in her palms. It was difficult to maintain the posture at first, but he became aware of an easing of pressure in his human back - no, a shortening! Sticklike arms flailed useless for a few more moments before they were absorbed into what was almost completely a horse's neck. Circe slowed the change some, allowing the foolish boy to enjoy as much of the change as she could. However, in another minute Ryan had completed the transformation into a Clydesdale stallion.
He felt confusion as equine instincts flared and pushed aside most of his human sensibilities. This massive body already felt natural to him, and new memories of growing up as a horse, nursing from as mare, being trained to pull plows and wagons, and then actual working as a horse became fixed in his mind. Abstract thoughts were dimming, concepts of math, writing, even time slipping away. But Ryan still knew he had been human. If he still had his full intellect, the boy might have finally realized just how much he had given up. Circe had been kind, and the massive draft animal now snuffling the straw of the stable was totally content as the beast he was.
