Jake licked his lips as all the evidence presented itself in front of him. The program was obviously much more than a standard run of the mill photo manipulator. Jake had always had an active imagination, and the prospect of something ethereal being involved with this software was inticing to him.
Still, the logical part of his mind told him, there was likely a very good explanation as to why the software had as much information on him as it did. At the moment he couldn't think of one, but he was sure of it. He slinked the slider bar for age up a few notches, stopping when the indicator read 21. He glanced down at the rotating 3-D model of himself on the corner of the screen, and didn't see any change. All he saw was the large glowing green "go" button underneath the model. Scratching his chin, he decided to indulge his fantasy for a moment. He stood up and removed all of his clothes, staring intently at the mirror that hung on his wall, before reaching over and clicking the mouse on the go button. A dialogue box popped up on the screen, reading "Adjust reality to match?" Shrugging his shoulders, but not really understanding the implications, he clicked yes and looked towards the mirror.
After staring at the mirror for a few moments, he felt embarrased that he had actually allowed himself to believe that this program would somehow magically change him. He was about to put his clothes back on when he felt a sudden tingle throughout his body. Startled, he stood up at attention and watched himself in the mirror closely. After a second or two, he groaned as he literally felt and saw his body stretch out. His arms and legs began to lengthen, becoming stretching the tendons and muscles in them to the point of nearly cramping. As they did, the muscles also strengthened, becoming thicker and more well defined. Jake smiled through the uncomfortable nature of the transformation as he saw his abs transform into a solid 6 pack, and saw body hair begin to cover his whole being.
"Holy sh...oh god my voice!" His voice cracked a couple more time, deepening into a strong rumbling baritone, just like his father. He felt a warm sensation pass over his face, and he marveled when he saw that he was a spitting image of his father, should he have been about twenty years younger. Another tingle, this one in his lower regions, directed his attention to his crotch. He groaned in pleasure as his prepubescent cock, nearly hidden in the forest of hair that had grown their, suddenly jutted out, becoming a full nine inches erect in mere moments. He stroked the erect organ, feeling a jolt of pleasure run through his body as the transformation ended.
He staggered back, mesmerized by the transformation. Before he turned back to the computer, his eye was caught by the rest of his room. What had once been the messy, disorganized room of a 12 year old had become much more orderly, albeit still a bit messy. The beanbag chair in the corner had been replaced by a set of weights. His desk was much smaller, but much more utilitarian. He glanced up at the photos on the wall, and stopped short. The camping photo of he and his father from last year had also been altered to reflect both his new age, and an older age for his father as well.
He glanced back at the computer, partly afraid of the power he had, but also intrigued by it. If he could do this much with one simple change, what else could he do?
