"I dunno, bro. I think it would be cool to be my old height. That way I would basically look the same, just with a lot more muscle."
Simon was actually kind of disappointed that his brother chose this. Apparently, his brother didn't quite understand the potential of the Chronivac. He decided to teach Adam a lesson about this.
"OK, here goes, Adam. Just wait up here, and I'll be back to check on you." Simon went back downstairs to re-program the Chronivac.
Simon figured that by reducing Adam's height to 5'8" and keeping his weight at 240, Adam would be huge for his height, certainly the most muscular guy at school, but that wouldn't teach Adam the lesson he was hoping for.
Simon programmed a 2-phase transformation. Phase 1 would take Adam to 5'8" 240, and that would give Simon time to get back upstairs. Phase 2 would give Adam another 100 pounds of muscle. Simon figured that would make his brother so muscle-bound, he'd have to agree to let Simon make him taller.
He programmed the changes and started the transformation. Almost immediately he could hear Adam reacting, and he rushed upstairs to watch.
"DUDE this is AWESOME!" Adam yelled in delight. At his new, older age, Simon's brain was starting to think about things like consequences, and he began to wonder what would happen when his parents got home. He decided he could handle that later.
Simon watched in amazement as his brother got shorter yet wider and thicker by the second. His upper arms had to be well beyond 20 inches and his quads were above 30. There might be time to measure stuff before phase 2 kicked in.
Adam stopped changing for a bit and hit some poses in the mirror. "Simon, this is awesome! How much bigger do you think I can get?"
Simon smirked as took some photos of his brother, so he could get Adam to appreciate what he'd done for him. "I think you're about to find out, bro."
"What....what's happening? I'm growing again!"
Simon watched in amazement as pound after pound of muscle piled upon his brother's compact frame. Within seconds, Adam's traps and neck got so thick that his head looked like it sat on top of a mound of muscle. And a mound of muscle is exactly what Adam was becoming. If only Adam had wanted to stay tall, then Simon could have turned him into a mountain.
Since he wasn't getting any taller, the muscles just kept getting bigger and bigger, limiting Adam's range of motion significantly. His shoulders were so big, that Simon doubted that Adam could raise his arms above his head without his deltoids running into his head. And those arms were so massive, his forearms looked like bowling pins, just shorter and wider. Adam's biceps, even with arms fully extended, seemed to hang off of his upper arm. They had to be over 25 inches, possibly approaching 30, as big than some bodybuilders' legs.
Adam's waist and legs had thicked substantially, as the muscle had to go somewhere. He had a tremendous muscle gut, totally ripped, even if distended somewhat. It looked like a tortoise shell was inside his abdomen. Adam's legs were ENORMOUS, his hamstrings so thick that, like his biceps, they hung from the leg. His quads were so thick, especially right above the knee, that they almost looked like fat rolls over a fat guy's belt. In Adam's case, however, his legs were all snaked out with veins, so you knew it wasn't fat. Everything was so massive that he had to stand with his feet very wide in order to stand. Simon had no idea if Adam would really be able to walk at this size; at least he'd have one heck of a bodybuilder waddle.
As the growth stopped, Adam looked at Simon in a mixture of pain and pleasure. "How big am I now, and am I changing any more?"
"Don't worry, Adam, not until you tell me to, and by the way you're 5'8" like you asked, but now you weigh 340 pounds."
"Wow, that's it? This feels really weird, but I think I kind of like it. Everyone will just have to get out of my way, if I can figure out how to move, that is."
Simon laughed to himself. "I guess I should have put him over 400," he considered.
