*Same time at Chris and Jeff house*
Chris whined, the last few inches of the stairs were the only thing separating him from Chronivac, and the only chance he had to stop his brother and friend and put everything in order. When Jeff altered his and Dominique's genetic code, Chris assumed that the effect would have affected him as well. They just couldn't get that big and he couldn't get that small. He reached up for the doorknob, which was much higher than he expected (because the world was experiencing the changes made by Jeff), and his arm strained against the mass of cum inside of his bloated stomach, trying to lift up his body to reach his target. He got up high enough to grasp the knob, and just when he got it, it opened, pushing Chris backwards and down onto his ass, moaning and groaning as the jello-like substance inside of him sloshed around his over-packed belly. He reach the giant computer chair and climbed on it.
He realized how hard it was to see over it when it was at it's normal height, and that was for someone almost 8 feet tall. He struggled with the seat height controls and got the chair to go as high as it could go, and he could barely see over the monitor, much less the controls of the device. Chris wanted to cry as he felt his size. His pushed a mouse button with his fist to open the Chronivac and started to change his profile.
After a few minutes the reality had started to change. Everything seemed normal, and then things seemed to be getting smaller... Better say, they become the size they should be. Chris sighed as he leaned back, satisfied, when his ass bumped up against the back of the seat. The chair started to wobble under him, the chair leaning back to counter the shift in weight, and it's limits being tested as he continued to feel heavier and heavier.
"Nnngggrrrr" he grunted as his muscles got tighter, and bigger. His arms were the first to bulge as he used all of his strength to balance, then his chest, which kept on bulging more, as did his legs. The seat leaned all the way back as Chris started to take up all the available space under the desk. He felt his ass slipping off of the chair and his arms and hands bulked up even more.
He didn't change a lot. Just wiped what Jeff's did to him and than Chronivac started to change the Universe back to previous information. Chris was a sportsmen, bigger, heavier and with more muscles than his little brother. And it meant that Chris should be a sportsman compared to 6'8 and 1200 pounds Jeff. So when he turned back to "normal" he became a man of his 20s, 7'8 tall and around 1800 pounds heavy of muscles. Chris groaned as the change finally ended. He had muscles all around the body and his pecs were as thick as Jeff's head. His cock, as he saw under the desk, was massive, with balls of similar size.
