Wanting a test subject Tom went down to the living room to find his younger brothers; eight year old Cole and ten year old Evan, engrossed in video games. Both were fairly slim and lightly tanned with Cole having his brown hair cut short and Evan wearing it longer and slightly fringed. Activating his chronivac functions, Tom targeted them both and moved to their muscle mass. In the form of a slider he raised both of theirs a decent ways and muttered "Activate change."
In an instant both boys grew and filled out their t-shirts and pyjama pants. Feeling the sudden tightness of their clothes, and the weight of their new muscle, they jumped up like they'd been shocked and looked each other over in surprise and awe. Cole quickly pulled off his too tight shirt and revealed a tight, muscular, gymnast body with toned, lean muscle, supple curves and a perfect rippling six-pack. "Evan, look at me!" Cole cried at last, "I'm ripped!"
For effect he flexed a sizable bicep and admired the ball of muscle that rose up. "Yeah well so am I," Evan replied, pulling off his own shirt and revealing a larger version of his brother's gymnast body.
Evan flexed his pecs forwards instead, and admiring the slabs of muscle that bulged up, while Cole cupped one just to see how hard it was. He couldn't dent it, and Evan had similar difficulty with Cole flexed his own pecs out. Then they crunched their abs, making the cuts in their abdomens go deeper. They continued admiring and exploring their newly enhanced physiques until they finally spotted Tom. "Hey Tom! Look at us!" Cole cried out as the two rushed over to him.
"Woah," Tom cried, pretending to be surprised. "You guys are ripped!"
"I think we have more muscle than you," Evan chuckled, looking over his tight body again.
"That's alright, it's kinda neat having ripped little brothers."
