As Tim picked up the box, he pressed the small red button and the big blue button (not the same). He felt really funny. Then something unexpected started to happen; the world and everyone else got bigger, too! They didn't come up to his 150, but it was like a 6' guy in a bar full of 5' men; he was still bigger. 'Great, everyone else and everything else is big, too!' He pressed the small red button and a big green one, and felt tingly.
"Aww crap!" He was growing again! But this time it was different. He was getting more muscular and becoming sexy, too. All the workers, whom were naked, got boners. As his body expanded, they jumped onto his feet and climbed up to his cock. They started to jack it off; note that he was still getting bigger, and his cock was now roughly 500' long; by that time he was 4000' tall.
As Tim went into orgasm mode,he stopped growing, and he pressed another set of buttons. They were both small ones; green and purple. Since he was in an orgasm, he didn't notice it, but his cock was getting larger.
When it was finished and he had cumed, it came to 1000'!
