It didn't take long for Tanner to come to a decision. As much as he wanted to relate to his younger brother, he had no desire to go through elementary and middle school again. Therefore, while his brother was still reverting back to his original size, he keyed in to the Chronivac to change Derrick's age to 17, to match his own. While in there, he also decided to make them both taller and a bit more muscular as well. Derrick had just finished growing when Tanner finished entering the changes.
"What are you doing," Derrick asked inquisitively, without the slightest clue what was about to happen. "Don't shrink me down to an inch again...whoa..." A tingling sensation fell over Derrick, and he could suddenly feel the room getting smaller again. He looked over at his brother, and saw that he too was getting taller, although only slightly as well. As he looked down over his body, he could feel his shirt pulling tighter against his chest, the sleeves cutting into his arms as muscles began to grow along his biceps. With some difficulty, Derrick managed to get his shirt off. He glanced over in the mirror on the side of the room and was shocked at what he saw. He now looked thirteen, maybe even fourteen years old, and he wasn't done growing yet. Quickly he ripped off his jeans before they were split into two from his expanding body, just quick enough to see dark brown hair start to sprout all over his body. His penis, a heretofore ignored organ, had grown as well, becoming six inches flaccid as it hung from his rapidly aging body.
"Whoa," Derrick whispered, startled by his deeper voice. Finally the growth stopped and he was able to take stock of his 17 year old self. He had hair covering most of his upper body, legs and torso, as well as a deep stubble on his face. Powerful muscles lurked beneath his flesh, and he flexed his arms, feeling the hard weight on his bicep. Grinning to himself, he turned to his brother and noticed that he too had removed his clothes, just to compare. Tanner was still slightly taller than his brother, by maybe half an inch or so. Both of them stood just over 6'6'' and were both very handsome. "Why did you do this?" Derrick asked, looking down at his body again, "Not that I don't want to be an adult but..."
"I wanted us to be more like each other," Tanner replied, clicking the Chronivac to check their stats now:

"Okay then" Derrick replied, looking at the Chronivac with a smile on his face. "But now I want to change something."
