Suddenly, Steve felt his room spinning around him. The computer disappeared from in front of him, and he could barely make out anything beyond his own body. The scene around him gradually resolved again into a room, but a different room from the one in which he had been sitting. He was in a bedroom -- a girl's bedroom, by the look of the row of blouses, skirts, and dresses in the open closet, the lilac comforter on the bed, and the prints of flowers hanging on the walls. He found himself sitting in a white wooden chair facing the bed.
Suddenly, the door flew open. Before Steve could think what to do, a young woman -- Melissa, by her resemblance to the photo from the website -- burst into the room and stared directly at him.
"What's going on here? I discontinued my account on that stupid website months ago!"
Steve didn't know what to say. "S-s-sorry," he stammered. "I just clicked on the button by accident. I didn't think it would do anything. I'll just leave... ." Flustered, he jumped up off the chair and started towards the door.
But suddenly he started to feel dizzy. He pressed his hand to his forehead and closed his eyes as he tried to steady himself on the nearby dresser. He was vaguely aware of Melissa leaning towards him. It seemed almost as though she was torn between supporting him and pushing him out of her room. And that's when Steve figured out what was going on.
He was getting shorter. He hadn't been tall to begin with, but he felt himself sinking down inside of his clothes. His shoulders narrowed abruptly, as did his waist, even as his hips and thighs swelled suddenly. He took his hand from his head and ran them over the outside of his new hips. They felt... round, and his butt, too, was plumping out even as he ran his hand over his lower body. His feet were shifting around inside of his shoes, and his hands and wrists felt smaller. Everything felt smaller, actually. He put his hand to his face and felt a button nose, a soft chin. Gone was the scant scruff that he had had just moments before. He was vaguely aware of a tickle on his neck, and when he reached back behind his head, he grabbed a handful of thick, honey blonde hair.
The biggest changes were yet to come. He gasped as he felt his penis suddenly shrivel up and disappear inside of him. At almost the same moment, his chest exploded outwards. He had breasts.
He looked up at Melissa, who was still staring at him. Behind her, he saw a mirror.
"I..." his voice was soft, like hers, and high, much higher than it had been only moments before. "I think I'm... you."
