You look around your brother's new car, realizing just how much the watch changes reality. The car was pretty messy, and the backseat was full of random stuff. Gym clothes, a basketball, a pair of well-worn Lebrons, another pair of clean Jordans, and although you aren't 100% sure, it looked like there were some condoms stuffed under the seat. Looks like Brady was a proper basketball jock now, with a body he knew how to use.
"How did you do it?" he asks again, interrupting your thoughts. Brady was never one to get greedy, but he is clearly enjoying his new body. The last thing you'd want is for him to take the watch from you, which would definitely be easy with his new size.
You look up at his now dazzling blue eyes. "There was this weird shop at the mall that was selling some weird stuff. I bought this watch that can change your age. I didn't know if it would work, so I tested it on you."
"I'm glad you did. I mean, look at me," Brady said, looking down at his pecs.
You couldn't help but look too. They were firm and stretching his t-shirt tight. You could see the clear outline of his nipples, straining against the fabric. Some chest hair popped up over the collar of his shirt as Brady flexed and bounced his pecs.
Brady put his car in reverse and started driving to school. You both went to the same high school now. It was definitely weird seeing your 10 year old brother suddenly know how to drive. Even though Brady was aware of the changes to himself, he still seemed to be affected by the reality changes. New knowledge seemed to have flooded Brady's brain. How to drive, how to play basketball, how to have sex?
"So, can you make me even bigger?" Brady asked.
"I don't think so. The watch makes you older, not necessarily bigger. You probably would have still looked like that even if you had aged normally." We must have good genes in this family, you think to yourself.
Brady pulled into a parking spot at your high school. You both get out of the car where you can really see him in broad daylight. Brady's probably about 6'3" now. Your head just comes up to his pecs. His tight white t-shirt shows off all the contours of his pecs and biceps. He's not huge, but definitely toned like an Instagram model. His jeans are dark and basically shrinkwrapped around his massive thighs. His new dick is huge, causing a significant bulge. His muscular calves lead into his newly enlarged size 12 feet, which are wearing what appears to be a brand new pair of Jordans.
Brady looks down at you, "It's definitely fun being this much taller than you now, but it would be even more fun if you used your watch and aged yourself up too. Then we could play on the basketball team together, hang out all the time, and even go to college together."
You look down at your watch and . . .
