Dustin sat down on this comfy wooden bench right at the entrance to a very large department store in the middle of the crowded shopping mall. It was also in the middle between the intersection of two hallways ending in two major exits, so there was a lot of traffic passing through that area.
This was where Dustin spotted a teenage boy, who was leaning against the glass door. He had just greeted a girl, who left a shopping bag with him. That was probably his girlfriend. The girl went inside while the boy remained by the door.
Somehow, thanks to Ty’s weird powers, Dustin learned that the boy’s name was Kenny. Dustin looked him over and started to stare at him. Luckily, Ty made it where nobody even noticed at all when Dustin was staring at someone for a long period of time so nobody could complain that he was making them feel uncomfortable.
The minute Dustin began to stare at Kenny, Kenny’s muscles began to bulge! His legs grew wider all over, with his calves growing much bigger while his quads widened until they almost burst out of his jeans. His jeans felt incredibly tight!
Kenny’s pectorals ballooned from his chest, filling out the white t-shirt until you could see that Kenny was very muscular. His arms muscled up as well, with big biceps and triceps growing so big, that the shirt sleeves started to tear on both sides. His torso widened with broad lats and rows of cobblestone abdominal muscles formed across his lower torso, which were now clearly visible through the thin t-shirt, which was about to rip.
Thanks to Ty’s magic, the t-shirt morphed into a tight, stretchy tank top, which allowed Kenny to show off all his new muscles in all their full glory. As Kenny looked down, he just smiled in wonder, for he had no idea where all the big muscles suddenly came from.
Dustin just giggled as he watched the poor, confused teenage boy. Kenny rubbed his hands across his big biceps, his pecs and his abs. He let out a soft gasp, as he admired his own amazing physique, which grew out of nowhere. Only Dustin knew that he had caused all the muscles to grow!
By then, the girl appeared, and they walked off, leaving Dustin satisfied that he had grown another skinny boy.
