Vince had been hitting the gym for months now, but it felt like his body wasn't listening. He'd put in the hours, but just didn't see it paying off. He was hoping to get huge muscles and had managed to get some definition, but after all his time he felt he should be bigger.
He consulted some of his friends, asking for advice on how to get there. They surprisingly suggested buying some muscle shirts, tight shirts designed to emphasize your muscles and make you look bigger. He took their advice, finding a website with branded muscle shirts for cheap, something to deal with wrong labels. He was a bit skeptical but decided to give it a try. When the shirt arrived he laughed, the tag reading XL but clearly being much smaller. It barely fit him when he put it on.
He felt the tight fabric stretching across his chest and shoulders, barely managing to get his neck and arms through the cuts. He loved how it framed his body looking down at himself, showing his definition. He could hardly move around in it, fighting against the fabric to turn. He could almost imagine this was what it must be like to be huge, not able to fit into normal shirts. It wasn't until he stepped in front of his mirror that he realized the full change.
He had grown. His chest and arms had swollen up into huge sacks of meat attached to his body, giving him a soft appearance. No wonder he had been struggling to move around- his mass had filled out the shirt entirely, his muscles even getting in the way of themselves. He couldn't have imagined being this size of a brute, absolute power and raw strength. He flexed for the mirror, taking a picture before heading to the gym. He couldn't wait to get even bigger.
