Steve carefully sidestepped around the unconcious Andrew, now a woman, and took the container of Transformation Salve off the counter. After applying a healthy amount to his arm, Steve made his wish.
"I wish that Andrew would turn into an anthro horse, and stay female." Steve said, a clear picture in his head of what he wanted Andrew to turn in to. He only hoped the Salve would be able to deliver.
It took a minute or so until Steve could see Andrew's body changing. The naked female on his bathroom was growing, muscles becoming more defined and toned. Steve sat down on the floor, his balls lying on the cool tiled floor. His cock was held in his hands, half limp but getting harder as he watched Andrew transforming.
She looked like one of those female bodybuilders who had taken one too many steroids. Steve kept his eyes fixated on Andrew's chest and nether-region. His horsecock shot forward when her breasts started to grow. They were enormous, past the size of basketballs and growing. Her nipples were hard, even though she was unconcious. Steve reached forward and pinched one between his fingers. Andrew moaned, and fidgeted. The changes were speeding up, and Steve began pumping himself. His cock strained in his grasp, blood surging through his veins.
Hair was started to sprout all over Andrew's larger body. It was dark brown, like the hair on his head which was also growing out. It was centered on the middle of her head, a proper mane starting to form. Her ears were pulled to the top of her head, becoming pointed and furred at the same time. They twitched every time a new wave of changes hit Andrew's body.
"Oh fuck, I wish I'd changed myself before. I wish I was a..." Steve thought, as he rubbed the length of his shaft. What he didn't realize was that he still had some of the salve on his wrist. And by making a wish, he would soon begin his own changes.
