Mike woke, feeling thick headed and disoriented. What was he doing sprawled on the floor? And why did he feel so weird? Opening his eyes didn't help. Vision was distorted and our of focus, and colors seemed washed out. And once he got used to that, he realized he was seeing two different sides of the bathroom at the same time!
He pushed himself up from the floor, having trouble getting his hands to grip on the tile floor. Something had happened in the shower. And before that! His mind cleared a little more, and tried to look down. There was something large and dark blocking his vision. A muzzle?
He gave a sudden cry of fright that emerged as a very horsey whinny. Twisting his head sideways, he got a look at the ceiling above... and his almost fully equine forelegs and hooves below. His hands had continued changing, along with the rest of his body.
Now he was picking up a strong odor - a mix of male musk and fear. His scent, plus the chemical stink of soaps and cleaners in the bathroom. Bracing himself, he very carefully pushed up again, this time managing to get his forelegs straightened out. As soon as they were firm, he automatically rose up on his hind legs and stood there a moment, pleased with himself.
Wait a minute! FOUR legs? Twisting a very long and flexible neck, he got a good look at the rest of his body and whuffled a sigh. Shuffling around to see what he could in the big mirror only confirmed his worst suspicions. He was a horse. A big, very black, very male horse.
It was sorta weird not to be terrified. He was a little upset, but not so much that he was scared or worried. After all, he was a really pretty horse, and once he finished changing... he stopped at that and glanced down at his forehooves. There were still breaks to indicate fingers, but they seemed to be fading away.
A familiar stiffening drew his attention back to his hind legs and the black sheath that hung between them. He was pounding out again, even bigger than before, the thick black shaft fully equine now. Damn, he was horny! His balls felt like melons hanging behind his new sheath, though he couldn't actually see them. His penis arched up as it hardened, and he felt pressure building.
Small squirts of whitish fluid began to dribble from the tip, the odor of musk even stronger now. He'd give anything for a mare now! The thought of a female horse brought renewed desire and need.
