Jim heard the door open and close. His older brothers, twins Wyatt and David, were home. The two were extraordinarily close and identical, with messy black hair, pale skin, thin bodies, etc. Both wore thick glasses.
The twins were gamers. They spent all of their free time playing video games like Call of Duty and Fortnite. They barely left the house. Jim figured they could use an upgrade.
Once they had settled in downstairs, Jim used the balloon to control the awareness of everyone but him of the changes. Then he set the balloon to control the twins' vision and blew hard. Wyatt and David suddenly set their glasses aside, where they vanished.
Next, Jim focused on their looks, blowing the balloon up even more. He watched their faces rearrange until they were perfectly handsome.
Jim synced the balloon to their muscles next. He gave the biggest blows of all this time. He saw their T-shirts tighten as their muscles filled them up. Soon Wyatt's shirt tore halfway down, letting his giant pecs spill out. David's sleeves split against his gargantuan biceps. Soon they were wearing nothing but strained underwear, having destroyed the rest.
After making them taller and deepening their voices, Jim finished by increasing their athleticism. To his amazement, the twins put down their game controls and walked over to a home gym that had just appeared. Both began lifting dumbbells.
Jim could hardly believe it! He had turned his gamer brothers into total jock hunks. Things were going to be a lot different around here.
