Andrew held the card in both hands and said, "I wish that Bruce and I swapped ages."
Right away, Andrew felt his body started to grow taller and stronger as he passed through puberty. He clothes began to feel too tight on his expanding body.
He looked over at his brother, Bruce, and watched as the former 18-year-old stud became younger and younger. The muscles he had been so proud of were getting smaller as he lost several inches in height.
Then, for a moment, the two brothers were both 15. Andrew looked much stronger and was already several inches taller than before. Bruce looked more awkward and skinny. He appeared to be little more than a small high school underclassman.
The changes continued as the brothers grew in opposite directions. Andrew's shirt was now pulled tight over his expanding muscles and his height was approaching 6'. Thankfully, he was wearing sandals, otherwise his much larger feet would have torn through his shoes. Bruce, on the other hand, was nearing 5' tall and looked like little more than a kid now with his skinny limbs and smooth boyish face. He had to hold up his pants as they were now too wide for his tiny waist. His shoes seemed clownishly large on his little feet.
The changes slowed to a halt leaving Andrew at 18 years old and Bruce at 12. Andrew looked his body over. He was now 6'1" and appeared to be well-built, much like his brother had been. He smiled, satisfied with his new body. Bruce did not appear to be satisfied at all. He was now 4'10" and probably was barely 70 pounds wet. He looked like little more than your average scrawny 6th grader now.
Andrew just chuckled pleasantly in a deeper voice and said, "Well, 'big' bro. Do you believe me now?"
