Ty spotted another boy in the aisles, looking at basketball shoes. However, all of these shoes were much too big for the boy. He was in the big and tall section, looking at the much larger specialty shoes that were carried. However, he seemed more in line with a Size 8 or so. Ty wondered why he was looking in the section. He wished to read his mind and learned that the boy had a secret fantasy - having really big feet. Even if it seemed weird, Ty wasn't going to judge. Ty wished that whatever pair of shoes the boy tried on next, he would grow to fit the shoes.
Looking around, the boy eventually picked up a "small" pair of Size 20 basketball shoes. He looked around to make sure no one was watching, then ducked into the change rooms with the shoes. Ty wished himself invisible and quickly followed.
Finding the bench, the boy sat down and kicked off his much smaller Size 8s, he compared his shoe to the larger ones and smiled at the size difference. The boy slid his feet into the larger shoes. He stood up and looked in the mirror with a big smile on his face, admiring the huge shoes.
Finally, the boy reached down and started to untie the laces but before he could take them off, the boy suddenly began moaning quietly, Ty looked at his feet and saw very little change, but then realized the boy's feet were growing in the shoes!
Suddenly Ty noticed something else. Ty had been a couple inches taller than the boy. Now he was eye level. As he watched, the boy's head slowly rose above his own. Ty noticed there were measuring lines on the wall behind him, showing the boy was indeed growing taller. He was now about 5'8", 4 inches taller than previously.
The boy continued moaning, his feet still stretching out inside his shoes. Ty could see his legs lengthening, growing longer and longer, thicker and stronger. Ty could also see the boy's shirt riding high now, exposing several inches of midriff with a hint of a six pack underneath.
The boy's arms grew longer and more muscular, lengthening before Ty's eyes. His hands grew larger, as they underwent growth of their own. As the boy passed six feet tall, his growth seemed to accelerate almost, his head inching upwards in the air. Suddenly, Ty heard a ripping sound. The boy's T-shirt couldn't take the stress from his wider shoulders, and had ripped off and fallen off. Seconds later, the boy's shorts also ripped off, leaving the boy in only his briefs. Seeing this, Ty made a second wish, that the boy would have an enormous cock to match his growing body.
At once, the boy groaned louder and Ty saw movement in the boy's underwear, the material beginning to bulge outwards as his cock began to stretch out longer. The boy's 3 inch soft cock began to grow, swelling up and occupying more and more room in front. The boy's balls also began to enlarge, trying to steal some space in the boy's briefs as well. Ty quickly wished for the briefs to not rip no matter how much pressure was applied, but to stretch out and deform.
By now, the boy had passed 6'6" tall and wasn't showing any signs of slowing down. Even Ty was amazed. How tall was he going to be? He had to crane his neck to look up at the boy's face, which was contorted in pleasure from the growth. Ty noted with a chuckle that although the rest of the boy's body was extremely large, his face still had the hallmark childish features of a barely-teenager.
Looking down, Ty saw that the boy's briefs were bulging out more now, and it looked to be an interesting battle. The boy's balls were slowing down in their expansion - they stopped just as they reached the size of tennis balls. However, his cock was still growing. Ty estimated that he was now seven inches soft. And still growing! Ty watched it twitch and pulse as it grew two more inches. A nine inch soft cock seemed fine to him.
The boy was STILL growing! Ty couldn't believe how tall he was now! The boy just kept on stretching taller and taller, growing larger and larger by the second. He passed the 7 foot mark on the measuring tape. Ty looked down and saw that his briefs were still swelling, his cock still growing out and pushing for more and more space in his briefs. Ty could actually make out individual veins on the surface, it was that large. Finally it gave a little jerk and stopped growing at a massive 10 inches soft.
Finally, the boy's growth started to slow, petering out and eventually coming to a stop. Ty surveyed the scene and almost laughed at the comical sight. The boy still had his early teens face and head, but below his head, the difference was comical. The boy towered over Ty by over a foot, and Ty was shocked to read 7'2" as the height next to the boy's head. He didn't look like a bodybuilder, but he still possessed a lot of lean muscle, like someone fairly athletic or at least casually worked out. The front of his briefs were bulging out in an effort to contain his intimidating cock, which was almost so long that it could run down one of the leg holes. And whereas before his legs had been skinny and short, they were now much longer and more muscular - and matched his enormous feet perfectly.
Finally, the boy seemed to "snap out of it" so to speak. He looked down and gasped as he saw his new body. Then he smiled wide. Finally he really had large feet! Experimentally, the boy shakily bent down and removed one of the shoes. He almost cried out in happiness when he saw his feet had grown inside the shoe to perfectly fit. He stood up and noticed just how much taller he was, he looked over at the measuring tape and was astonished to see 7'2".
The boy looked down and saw the enormous bulge in his briefs. Almost as if in a trance, he removed his underwear and watched in amazement as his fat cock spilled out of his underwear, hanging down low. Behind it, two enormous nuts that were slightly bigger than tennis balls hung down. Almost at once, his cock began to harden, slowly inflating with blood and growing even larger. The veins pulsed. Finally, his cock stood erect at a massive 14 inches in length, and as thick as a soda can.
The boy stood in shock. He wasn't sure what to do.
