Lee had been going to end it – he didn't need to be any bigger than his already incredible size, and he'd show how he was big-hearted too by letting Charlie keep his masculine build. But his arrogant tone had changed Lee's mind. He needed to be taught a lesson. “It's not over yet. I will tell you when it's over.”
“Beginning phase six.” Lee watched Charlie gulp and turn toward The Contraption, this time facing it with dread instead of anticipation.
“Lee, please, you have to-”
“I'll tell you when it's over. And I'm through with you telling me what I have to do.” Lee smirked to see Charlie purse his lips. It was a funny sight to see a hunky guy, naked, growing bigger yet, but frowning and furrowing his brow.
A few times during his growth Charlie turned to the larger man, about to speak, but Lee just raised his eyebrows and that was enough to silence him. Lee enjoyed having this power – Charlie was certainly learning his lesson today.
After what seemed like ages, the amber liquid ceased to flow, and the pump clicked on. Lee moaned in ecstasy as he again felt his body – every part of his body – growing. He was already huge, but that just meant more of him tingled, and burned, and grew.
But while he was reveling in the sensation, he was not watching himself grow – he was watching Charlie shrink. It wasn't long before he was back to his normal size, but he did not stop there. As his head sank closer to the ground, his shoulders neared each other, his arms thinned, and his pecs deflated, his pride and joy, his once-mighty cock – no longer erect – retracted towards his body.
Lee glanced at the tanks to be sure, and then announced, “Hey Charlie. I'm twice the man you'll ever be.” Lee almost laughed at Charlie's piteous look. “Well, twice the length. I'm also twice your diameter, which means four times the cross-sectional area, and eight times the volume. Think about that. It would take eight of you to be as big as I am. Oh, but there's nothing 'eight' about you any more, is there?”
By the time he finished his taunting, around the time the fish tanks balanced, Lee stood more than a foot taller than Charlie, and was at least three times his weight. When the pump clicked off, Charlie looked up at Lee, imploringly. Just as Lee was about to end his fun, Charlie blurted “please, Lee. I'm average.”
