Now that Jake had familiarized himself with the program, now's where the real fun begins. Jake always thought his figure could use more muscle, and the solution had literally showed up at his door step. Jake got back on his laptop and started typing in "muscle growth" in the tab. A slider appeared at the bottom of the box labeled "growth percentage'. Jake noticed the slider was in the middle of the bar, but the bar displayed 100%. Would that be his current muscle is at as much as he could get? Or is it just a base start to even out how much muscle had gain? Regardless, Jake figured he knew how it would function, so he set the bar up to 150%. Jake imagined himself with powerful muscles before commencing the changes. It made his tail wag from the tip. With a grin, Jake hit enter.
Much like his tail, Jake began to feel pressure build up in his chest. He quickly removed his shirt in order to keep it from stretching. Once Jake pulled his shirt off his head, he noticed his chest was already reshaping itself. He was more toned than he ever imagined. Not only that, but his entire chest was growing. His pecs started swelling with veins, and his abs were shaping into a six pack. Jake felt his new muscle mass, envying the feeling of it all. His back was also adjusting to his new size, leaving his neck to nearly disappear in the mountains of muscle.
Jake's forearms were next to grow. His biceps were swelling to an abnormal size for an average human. Veins started creeping out to show how much pressure was going though his arms. He couldn't help but start flexing, almost as if his body was begging him to. The growth stoped at his wrists, leaving his hands the same size as originally.
Jake's pelvic area started feeling the pressure next. He noticed his crotch was starting to leave a bulging growth, leaving Jake blushing. He had no idea his genitals would be affected, but nonetheless he didn't mind watching them swell, leaving about two coconut sized spheres pushing the fabric of his jeans from his crotch. Jake felt a similar rush of pressure. It was like his tail, but a bit more below it. He looked back to notice his cheeks bulging and swelling, almost making a cushion for his tail to rest on.
Jake was feeling the pressure spread to his thighs. They started gaining more mass, giving off the veiny look the rest of his body was emitting. His calves were also thickening all the way to his ankles. At last, Jake finally felt his body in general was getting bigger. Every muscle that grew was now enlarging ever so slightly. Jake couldn't help himself as he flexed in response while growing.
The changes finished, and Jake was now looking like an 8 foot tall steroid injected weight lifter. Jake was so surprised to how much he had grown, he couldn't even see his full body in the mirror anymore. The only parts that haven't changed, was his head, hands and feet. Even so, Jake was happy with how his body turned out. Maybe 150% was kind of stretching it, it still felt like a dream for him.
Now Jake stood with muscles bigger than expected, and a tail of an alligator. He was curious of how much more the program would be capable of.
