Matt knew just what to do; he opened up the information about Chris and saw a lot of detailed options and facts. Matt saw "social group" was nerd. He changed it to "Football jock: 100%". He chucked to himself thinking how different Chris would be as a jock. He set the duration for 3 days, as he wanted to observe the changes over time. He also made it so Matt was the only one who would notice the changes. He clicked enter and closed down the chronivac. Matt shut the lights out soon and both of the boys went to sleep. Chris, however, had a very restless sleep as his body began to change.
The next morning, Matt was woken up by a continuous sound. He opened his eyes and tried to locate it. He noticed it was a continuous grunting sound. Matt looked and saw Chris on the floor doing a vigorous set of crunches. Matt was shocked! Chris looked quite a bit different from last night! Chris was only in his boxers. Chris noticed Matt was awake and said "oh hey, man". Matt noticed that Chris's voice wasn't as squeeky or girlish anymore, and he had a small bulge in his throat!
Chris stopped his crunches and got up. Matt could see he was 3-4 inches taller than before, and he had a lot more muscles! He still didn't have that much, but compared to his twiggy body before, he certainly did. "Just finishing my usual morning sets. Sorry I woke you", Chris said in his surprisingly deep voice.
With Chris only in his boxers, Matt noticed that he actually had body hair! He had a small tuft poking out from under his arms, a line of hair from his navel to his boxers, and a swirl of thick brown hairs around his nipples. This was crazy! Matt knew for sure that Chris didn't have a single body hair on his body before this! And he had never known Chris to work out ever!
His eyes trailing down Chris's body, he could see that his friends package was a lot bigger than before. It still wasn't huge; probably just average now. But, Matt had seen Chris changing before and what he had spied was very tiny. And almost completely hairless as well.
Chris quickly dressed and headed out the door; alright I'm off to my classes. See you later dude!", Chris bellowed out. Matt was in shock! He had already changed so much, both mentally and physically. And Chris still had 2.5 more days to keep changing!
