Aiden, 22 and bisexual, watched his pale feet swell and surge out of his shoes. They made quick work of the size 9 canvas sneakers and ripped through his socks with ease. It wasn't like nothing he'd ever seen before--he hadn't even changed shoes. Something in that muscle stud's spunk must have caused a mutated transformation in Aiden... he had to hurry and put on a pair of real shoes before his feet were too big for him to walk!
Aiden jogged through the aisles, past his usual sizes, as his feet stretched over the linoleum tile. They were already starting to approach a size 15 or 16. Aiden panicked a little and almost tripped over his own enormous toes. It was like there was a weight strapped to the ends of his legs. The sensations of the cool floor underneath him sent shudders up and down his spine. His feet weren't just growing in size, but in sensitivity! After a couple of minutes, he was already half-hard just from running. Aiden stopped to catch his breath and watched, transfixed, as his feet grew out inch by inch, taking up more and more of the floor. They were slightly disproportionate on him, but the abrupt transition from enormous foot to average ankle was kind of hot. The edges of his toes brushed against a rug, making Aiden's cock rock-hard and straining against the zipper of his jeans. Aiden briefly considered stopping there, sitting down, and allowing his feet to get as big as they possibly could. He debated massaging their soles himself. He even considered attempting to give himself a foot job. Aiden had to concentrate to break the stream of aroused thoughts. He palmed his erection--which felt oddly hot and swollen, thicker and longer than usual--through his jeans and kept going.
By the time Aiden reached "Special Sizes," his feet were growing past size 20. A recent surge in gay foot fetishists had left the shelves almost empty. He scrambled to look up and down them, pressing against the metal shelves to feel in the back for more shoeboxes. Aiden half-consciously humped the edge of a shelf as his toes grew under the bench on the floor. With his feet edging past size 24, Aiden grabbed the first pair he could find.
