Aaron was flipping back and forth between windows, when he opened a window that he had been looking at yesterday. It was that hot muscle car that he wanted as soon as he turned 16. He flicked back to Chronivac 4.0 control panel. He selected the option for automobile and then clicked and dragged the image of his dream car into the Chronivac's import image window. Then he clicked on his image and then the image of the automobile. His image suddenly tinged silvery on the edges, and his skin began to tingle. Aaron was startled and jumped up overturning his chair.
His throat felt constricted, he tried to clear it. Instead of the expected "Harumph!", a mechanical "Vroom!" came out. His hands began to balloon, and he found his teeth expanding in his mouth. Aaron looked around his room, as he realized a car wouldn't fit too well in his small room, and there was no way it could drive out the door and outside without making a hole in the wall. He dashed to the keyboard, but his fingers had fused as they expanded. The back of his hands had begun to resemble tire treads. He looked at the window, and then at his reflection in his dresser mirror. His shoulders had widened to over 3' and were still growing. The ceiling was now only about 6" above his head instead of the usual 24", he was growing bigger, and the computer read "Subject 8% Converted". Aaron dashed to the window. He tried to shout, but the only sounds he could make were like that of a revving engine. He discovered his teeth had fused, so he couldn't even open his mouth, and in the mirror, he saw that they now gleamed like chrome.
The sound of wood splintering and the cracking of glass was followed by the window swinging open. His fingers had been unable to work the lock properly but with his increasing mass, his fumbling wheel hands had broken the window open. Aaron pressed his arms to his side, and crouched as much as his changing body would allow. He climbed through the window and dropped down into his backyard. His body continued to grow. He must've been as big as bear.
"What's all the noise?" called a voice from beyond the fence. Aaron recognized his twenty year old neighbor's voice.
Aaron turned toward the voice and vroomed loudly.
He fell forward on to all fours. His shoulders widened to 5 feet, and Aaron's eyes grew into shiny saucers. His feet and hands had become mag wheels clad in radial tires. His teeth had grown into a chrome grill. Aaron could feel the engine roaring under his hood. His view of the world changed as he realized he was staring out of his headlights. The gate swung open, and the neighbor walked in.
"Cool, looks like I've got a new set of wheels, and the keys are still in the ignition!"
