Up to this point, Kevin had only been growing one boy at a time, but he felt up for a challenge. He looked around the playground. There seemed to be a dozen or so kids there, and among those seven boys, from the ages of five to twelve. It seemed to be like a good point to flex his powers.
He stepped to the far end of the playground, so he could see all the boys who were playing. He then looked at them all and focused hard, furrowing his brow. The veins in the side of his head began to show as he concentrated all of his power, and his vision began to blur, so he closed his eyes to eliminate all distractions. Once he felt he had taken control of all of the boys, he let his energy flow into them.
He didn't exactly have much control over what kind of growth was happening, as he was already straining enough just to grow seven boys at once. Because of this fact, each of the boys experienced the growth differently, in a seemingly random pattern. Mike, the boy who Kevin had grown before, didn't receive much additional benefit, only growing a few inches taller than he already was (still unbelievably impressive with his muscle mass).
Another kid, at the jungle gym, who was the oldest among the group at twelve, began to develop impressively, as his muscles bulged outward and he began to resemble the image of a Greek mythological hero. This boy's brother, a couple of years younger than he, benefited by growing substantially taller, more than doubling his height to be twelve feet tall, and now was sitting down underneath the jungle gym, crouching to avoid hitting his head on the bars.
The youngest kid on the playground, a skinny five year old boy of Chinese descent, received his growth in the form of an age increase, growing taller, increasing in strength, and developing more handsome features, until he was a fifteen year old hunk. He was playing tag with his friend, who also increased in age until he was a handsome fourteen year old lad.
Finally, the biggest change of all was to a ten year old boy named Juan. Before, he was playing by himself on the slide, skinny and rather short, the height of some of the eight-year-olds. He began to grow in every way imaginable. First, he shot up in height, first to six feet, then seven, then nine. At that point, he kept getting taller, but he also started developing muscle mass, in a big way. His shoulders began to push apart, his biceps swelled to the size of basketballs, and his thighs started to resemble tree trunks. And he kept growing. By the time Kevin was done, Juan was twenty-five feet tall, and had the body of a god. He still had the face and mannerisms of a ten-year old, but his figure looked anything but young.
Kevin dropped his head and released his focus. He started to feel very light-headed, and had to sit down on a bench. He looked at the kids, and saw that most of them were still playing, but the boys were now segregated from the girls, as not to accidentally injure them with their bulk and size. The two boys who were now teens were throwing a football around on the grass with their shirts off. And Juan the Giant was busy letting some of the small kids ride on his shoulders, enjoying the view.
So far, all was going pretty well, Kevin thought. But then something unexpected happened.
