A loud gasp escaped Trevor’s mouth and his eyes went wide as soon as he felt his jaws being force forwards in his head, releasing a series of shrill pops as it did. It didn’t hurt, but it was certainly unsettling.
As his incisors grew long and flat and his molars broadened out, Trevor took in a deep breath through his expanding nostrils. He was growing a muzzle!
For a moment, his eyes were focused on the single mass spreading out in front of his central line of site and he experimentally ran the tongue that felt like it was being pumped full of air over his new horse teeth. Then a jolt at the base of his back made him double over a bit. Something was pushing its way out of his backside.
Glancing back, Trevor watched in a mix of horror and fascination as his tail started to come into being. Eventually, the nerves started forming along with it and he could feel the new appendage growing and gaining muscle. Trevor’s heart fluttered when he flicked it and felt the still hairless tail slide over his expanding rump. Within a matter of seconds, it was about a foot and a half long, and Trevor was able to stand up somewhat normally again. It wouldn’t last long, though.
An instant later, his eyes were drawn down to his feet as they started cringing on their own. Feeling uneasy, Trevor lowered himself down onto his side and watched on as his toes reshaped themselves to where the middle digit on each foot became a single mass, then grew exponentially. The nail turned black and thickened while the rest of the digits receded into his foot, which was growing longer by the second.
While his rear hooves began to take form and his legs began to shift into a more equine configuration, Trevor winced his eyes at the slight stinging and burning sensation that erupted over his body. When he opened his eyes again, he realized his skin was turning darker and thicker as his skin became his hide. No sooner had it finished than another prickling feeling washed over him as dark, reddish-brown fur started covering every bit of him. It became most intense on the back of his elongating neck and down the length of his tail, causing him to flick it wildly until the burning subsided, leaving him with a tail and a mane full of long brick red hair.
Trevor rolled his eyes as his muzzle neared completion and forced his eyes onto the sides of his head. Back behind him, he felt his undercarriage reshape itself into an equine’s. Trevor opened his eyes in shock and found the world split in two with an enormous field of vision in each eye. He closed his eyes and struggled to gain control of his new sense of sight. Through it all, he missed seeing his arms elongate and his hands shift into hooves, just like his feet had already done.
By the time he’d mastered his vision, the changes had subsided and he realized he was nothing more than a horse lying on its side.
Trevor flicked his ears and his tail excitedly before letting out a horsey snicker. He was a horse!
Craning his long neck up, he tilted his head to the side and glanced over his new body with his left eye, intrigued. A bulking mass of deep reddish-brown fur and powerful hind legs greeted him. He focused on his back end and forced his tail to flick up again, whisking the long strands of hair up into the air before they landed across his outstretched back leg. He could actually feel the strands of his tail across legs and the odd shift in weight on the tip of his tail. Another excited nicker escaped his thick lips.
Taking a deep breath, Trevor rose up, guided by instinct, and stood up on his four legs. His ears flicked at the sound of his hooves clopping against the hard sand and the way it echoed across the room that seemed so much smaller now. Standing on four legs was definitely different, and feeling the weight of his tail sagging down over his backside and the strands of hair tickling the backs of his hocks was quite alien. Still, Trevor was more excited than anything.
