Brad paused, looking at the screen of the Chronivac, trying to figure out what to do. He saw the scan of your daughter in the next room, along with Dean, the little boy she babysits because his mother, strangely and miraculously, had conceived at the age of 53, and now at 58 had a 5 year old son. She'd given up hope of conceiving at 40.
He considered how the Chronivac might fix that if he just upped Dean's age to eighteen, so he could actually help his mother out. Brad played with the slider bar for Dean's age, and upped it to eighteen, then realized that it wasn't quite fair to Dean to lose thirteen years of his life, even if they were back-edited into his memory, so he decided to give him a few bonuses. He increased Dean's build to that of a massive football player and upped his height to 6'10" then just to be crazy, gave him a foot long cock and a face like a teen idol.
Just before hitting APPLY, Brad noticed a check box for "Exempt Self" and clicked it. When the Chronivac edited reality, he didn't want it to change his own memories!
He clicked APPLY, watching as Dean began to get older, his Bob the Builder shirt turning into a Spiderman one, and finally changing into a football jersey, worn without the pads but the massive teen still filling it out.
Dean was there in the next room, giggling happily, "It's so cool! I've been offered a football and basketball scholarship to State! And look at the bike they got me!"
He opened the door, revealing that his tricycle had remained a tricycle, but upped in size to a massive three-wheeled Hogg capable of transporting the teen's vast bulk.
