David scrolled through his information until he found one labelled muscle. It was represented by a slider with a plus at one end and a minus at the other. It was currently closer to the minus. Out of curiosity he dragged the slider towards the plus end. It didn't take long for him to notice his clothes becoming tighter. He released the slider just when it felt like his clothes could take no more, and looked down to see his t-shirt stretched across a broad, muscular torso.
The stretched shirt outlined smooth, powerful pecs above a perfectly defined six-pack that even showed through his stretched shirt. His sleeves had torn around round, muscular shoulders and thick, powerful arms. He flexed a bicep and marveled at the powerful young muscle that bunched up and tore his sleeve.
David’s pants weren’t much better. His boxers were torn around his round, muscular rear and thick, powerful legs; not to mention a rather larger bulge in between. Yet he was only slightly taller. Part of him wanted to slide the muscle slider all the way to the end to see how big he’d get, but another part wanted to go inspect himself in the mirror.
