From where Wendy was squatting with her black tail swishing for the first time spreading new mare pheromones the sounds of the others’ shouting filtered through the leaves of the trees and bushes between them.
“Ahhh! The pain!” the raspy voice of a man bellowed from the edge of the trees behind the four human members of the equestrian club. Midnight, Marcus’s big black stallion bucked and kicked the air behind him as his head rose and neck was forced into bending up and back. The stallion’s black horse fur sloughed off his neck and head revealing smooth skin like a human’s. His upper body glowed in the moonlight as his long horse neck pulsed and throbbed, two nubs pressing out of the top of the widest part of his expanding neck as took on the shape human torso. He snorted like a horse and stopped, took a breath and coughed exactly like a human, clearing his throat. “Simply incredible” he said in his deep voice, the pair of nubs toward the top of his neck starting to unfold into the upper arms of a centaur. He looked around at the people and the horses and then raised his head and swished his tail, his nose having picked up a delicious scent.
“Gosh, this is peculiar” a new woman’s voice spoke with a twang deep and raspy and the group turned toward the sound, realizing it was Wendy’s horse June, a brown quarter horse mare speaking, her changes following the other horses’ in her gaining the ability to talk. The changes seemed to be picking up speed and more of the team and their horses were progressing as Luke and Snow had.
“We’re all changing, even our mounts!” Marcus said looking at the three other’s faces, the orange glow of the fire across them, before his gaze was drawn up toward the handsome rugged face of his stallion, Midnight looking back at him. The Hispanic jock’s gaze lingered for a moment on Midnight. “Holy…” With his long black hair and strong jaw with dark stubble, Midnight looked remarkably similar to one of the guys on Marcus’s wrestling team back in high school. Suddenly Midnight was looking woozy. “Woah! Steady, boy” he said without hesitating as Midnight started to sink toward the soft ground passing out as Luke and Snow had when they changed.
Just as Marcus took his second step the denim of his jeans gave out and his pants split down the sides of his thighs and his fly busted open, a huge dark tube of flesh flopping down to his knees. Marcus stopped, his big dark hoof snapping a dry twig. He reached down to cup his hand over himself in modesty, his brain not keeping up with or computing how his cock and balls had swollen into the hefty set of male equine genitalia befitting a stallion.
“Holy cow!” and “It’s just like Luke’s!” Lucy and Amanda said watching as Marcus took another step toward Midnight, both of his feet now the big heavy hooves of a draft horse, long white hair spilling down over them from the tops of his two weirdly thick looking toe-knuckles all the toes on each foot had merged into, as his fetlocks grew in. A long dark tail matching the stubble of his buzzcut hair grazed down the backs of his swelling and stretching thighs. His expanding hips and groin were suddenly beyond his reach of his hands as budding forelegs unfolded from the tops of his lengthening hips. The jock couldn’t help stumbling as his legs cramped up from growing and stretching longer into the powerful hind legs of a Clydesdale draft horse.
Marcus clenched up forward falling down to the knobby knees of his forelegs pressing against the soft grass of the clearing and dry heaved, his upper body swelling as his physique expanded, the muscles of his upper body growing as he picked up size to match the expanding bulk of his draft horse lower body. He grunted deep and snorted like a horse before making a few guttural sounds like a beast, and then slumped forward and rolled onto his side, joining the other three centaurs in becoming part of this world.
Amanada and Lucy and Ben stepped closer to him, the three already had much fewer than thirty toes touching the ground as they stepped to watch the newest centaur twitch and grunt involuntarily as the changes progressed and his body expanded to his new size bigger than even Midnight. His four horse legs occasionally twitched while his arms were pinned underneath his upper body, the chestnut fur of a Clydesdale spreading out from his groin up over his lower torso and four horse legs. His buzzcut shagged out into a mop of long black hair down scattered over his shoulders and face as a pair of long triangular horse ears slid out from between his black locks.
