Sam held the Chronivac in his hands, feeling the massive bulk of Glen resting atop him. He couldn't get out from under his now quite big friend -- 350 pounds of muscle didn't move that easily for a puny thing like Sam.
Sam brought up his own profile, thinking maybe if he became a little bigger, he'd be able to get out from under Glen. He looked at his own stats, a very ordinary 5'9" and a positively puny 136 pounds. Glen weighed two and a half times as much as him!
Sam worked on the sliders. Maybe if he was 200 pounds, he'd be strong enough to move Glen... He entered the figures, but then paused. Why stop there? Small as he was, he'd always been the bigger of the two of them, even if that just meant he was a hair less scrawny. Knitting his brows, he altered the numbers he'd entered, doubling the weight, increasing his height. For good measure, he gave himself another five years of age as well, and a hefty cock and balls. Then he hit enter, and felt a shiver go through him. And then his body began to burn, burn like a wild fever was running through him. He gasped in shock, but it became a groan of anticipation as he felt his body begin to change.
Above him, Glen stirred, slowly waking to the sound of Sam's moans. "Sam...?" he asked groggily, "What's..." His voice trailed off as he felt Sam swell beneath him, his small friend getting taller and more muscular. He heard a low chuckle come from beneath him, as Sam's eyes rolled back into his head, a big grin on his face as he enjoyed the rush of growing muscle.
"Oh fuck yeah..." Sam drawled, his voice dropping an octave with every syllable.
Glen grabbed Sam's arms. "What did you do?" he demanded. Sam grinned back at him, and slowly flexed his growing biceps, the big round muscles rising, pushing outward, hard and bulging, forcing apart Glen's grip.
"You were too heavy for me to get out from under. But not any more..." Sam finally explained, as he felt his growth finish. He sat up, lifting Glen up and off of himself in the process, and slowly stood. He positively loomed over Glen, a massive example of manhood, 21 years and six feet, six inches of rock solid muscleman, 400 pounds of pure brawn. He turned toward Glen, giving his friend a good look at his huge new body, and the big cock that was swelling between his legs, stretching outward and upward until it reached a full foot in length. Sam smirked cockily, loving the expression of surprise and awe on Glen's face. Sam bounced his big pecs experimentally, and began to flex his muscles, one by one, his excitement growing. Glen was getting hard as well, and crawled across the bed toward Sam, reaching out to explore his friend's huge new muscles, much as Sam had done for him earlier.
