"I wish I would grow while keeping the same proportions as what I had before!" As soon as Chris said those words, his body started filling out to go back to the way it was before he started growing. "There!" he exclaimed, pleased at himself. He still looked like a skinny twelve-year-old, but at least he wouldn't turn into a stick-man or something like that. "Besides," he reasoned aloud as a sly grin came to his face, "I can always add on muscles or something like that later."
He looked at himself in the mirror, pleased with what he saw. Getting back to his previous proportions had caused his clothes to become much too tight now, even forcing the button on his shorts to pop open and the zipper to start to unzip itself. "Heheh, I suppose I could do something about that," he chuckled, "but I'd kinda like to see what happens if--" he stopped himself. "Actually, yeah! I wish I would grow until I've completely outgrown my clothes!"
Instantly, the sensation came over him again and he started to get taller. The fabric of his shirt pressed tighter and tighter against his skin, making noticeable stretching and ripping sounds. After a few seconds, his shirt finally burst off, and his shorts fell apart a few moments later, leaving him in only his boxers. They had always been a little loose before, but now they were extra-tight, causing his manhood (excited by all the growth he was experiencing) to force its way through the flap.
His growth still continued, forcing the underwear to the breaking point. Finally, they, too, ripped apart and fell to his feet, leaving him naked, and causing his growth to halt. He looked down at his now-huge body, smiling broadly. Measuring himself against the marks on the door, he guessed he was now 6' 3"-- a full two inches taller than his brother!
"It would be great to go see what Nate thinks of me now," he thought, "but is this gonna be enough?"
