Cody looked around in shock as his loose clothes hung onto him. Looking down, he saw his pants start to fall down and he had to keep them from completely doing so. He was tiny (at least for his standards)!
Seeing this, Matt smiled at his older step brother struggling to keep his clothes intact.
Cody then looked up to see that smile and got even angrier.
“You did this to me! Didn’t you?” He shouted as he lunged at Matt. Even with his smaller size and loose clothes, he quickly grabbed Matt in an advantageous position and held him tight against the wall. “I may be smaller, but I will still kill you if you won’t change me back”.
Matt knew that Cody would still cause him a lot of immediate harm with his muscular body. He had to to change his step brother back.
Then, both Matt and Cody felt the world around them get smaller and smaller and then it stopped. Cody was once again at his original height with his original proportions, and Matt grew to be a few inches taller than that, as his wish that he was bigger than Cody still took effect.
“So you changed me back, that’s good, but don’t think I’m done with you even with those extra inches you gave yourself” Cody said, still pinning Matt against the wall.
Matt knee that he still had no hope against his brother. He had to be much bigger than Cody, and now.
He then felt his body rise up once again, Cody struggling to keep his grip on him until he had to let go due to being too high.
Matt now complete dwarfed Cody at 10 feet tall, having to bend down in his own room, and then a surge of growth came to him and he grew wider as muscle mass increased all over himself. As it ended, he was decently muscular, not as much proportionally as Cody, but at his much greater height he was certainly stronger, and all his clothes were once again ripped off.
“What do you mean in ‘I’m not done with you’, LITTLE brother?” Matt said with a huge smile on his face as he grabbed Cody, picked him up, turned around and pinned his against the wall. “You still look tiny to from my point of view, and I don’t think you could really do anything to me, could you?”
He then dropped Cody to the floor, who himself quickly ran away from his step brother’s room.
Matt was extremely happy. He loved his new size as it complete dwarfed Cody’s and intimidated him, though it may be better of the ceiling was farther away. Just as he thought that, the ceiling did so until it gave him a bit of standing room.
He then actually took a look at his naked self, seeing a long body with fairly large muscles. Then his glance went to his normally small manhood, which looked ridiculously tiny on him now, and quickly wished that it would be huge by itself. I’m seconds, his small penis grew from its original meek size to the biggest thing he saw. It was huge! Probably dwarfing his brother’s even in comparison to their height.
After that, Matt quickly wished that his clothes would rewove once again and fit him, and seconds later he was once again fully clothed, though there was a notable bulge in his pants.
