Steve stuck the needle into his arm. A feeling of pleasure rushed through his body. He began to grow bigger, his muscles swelling...wait, no. They'd already stopped.
Steve examined himself. He looked almost exactly the same. His biceps were a little more defined, his pecs jutted out ever so much, and his stomach was flat, but that was about it. Well, at least it did something, he thought. But that didn't keep him from being disappointed. He had expected more.
What Steve didn't realize was that the nanobits were glitching, turning on and off. Whenever they turned on, the resulting current would cause growth. But it would be highly unpredictable; Steve was in for a rough road.
The next day Steve had some classes to go to. In his first class, no sooner had he taken his seat then the pleasure wave hit him again. It was a short burst, and when he looked down, his chest was slightly bigger, his arms were a bit more defined, and he had faint traces of abs, as well as slightly thicker legs. He wondered if maybe he just hadn't looked as closely the night before.
Steve went through much of the rest of his day without anything strange. But halfway through an afternoon lecture, he felt it again, and it wasn't stopping. He got up and dashed out of the lecture hall, leaving the girl behind him wondering if that nerdy guy had looked bigger.
Steve found himself in an empty hallway. Unable to find a bathroom, he prayed no one saw what was happening. He watched in awe as his muscles swelled to large sizes all over his body. Soon his shirt was fighting to survive and his pants were barely hanging in. Steve was pleased, he definitely fit in with the jocks now! But little did he know that it wasn't over yet.
