Josh was nervous. He'd never had a girl his age over to his house before, and Ally was really cute. He wanted to impress her. Like him, she was only 12, but she was intelligent, though not a genius like him.
Josh showed Ally into his basement lab. "This is where I perform my experiments," he explained. "Lately I've been working on a growth formula. After some trial and error, I think I've created the right concentration."
"A growth formula? But only movie scientists make those," she said curiously, eyebrows raised.
"You know the giant woman a few months back? That was my babysitter, Megan. Oh don't worry, she's adjusting fine. I've talked to her recently and she seems happy."
Ally decided to take a chance. She liked Josh, and thought he was cute and sweet, and was definitely going places. But she figured if this formula was all Josh said it was...well, she might like him even more soon.
"I don't believe you. If it's really as good as you say it is, then I dare you to drink some so you can show me," she said with a grin.
Josh was perfectly willing to take her up on it. He poured some formula into a vial, threw back his head, and gulped it down.
The two waited for an uneventful minute, before Josh let out a small groan. His body stretched as he grew a couple inches taller from 5'3" to 5'6". Then his shirt grew a little tighter as small pecs appeared, a couple abs formed, and his arms grew a little thicker. Josh had probably gone from 110 pounds to 120, gaining 10 pounds in the process.
"Wow! It really worked!" Ally gasped.
"I know. Like what you see?" he teased with a grin.
"Well, as a matter of fact, I do," she said back.
The two spent more time down there. Before she left, Ally gave Josh her number with a wink.
A couple minutes after she left, he stood there still clutching her number, happily surprised. Then Josh checked out his body. Definitely an improvement.
