Ryan looked through the many shoes, until something spotted his eye. They were black Adidas runners, with white highlights. Ryan admired the shoes, and felt a strange draw to try them on, but there was no way they could fit him. Still though, he needed to try them on. Ryan took one of the shelf, and checked the tag. Size 15. There was no way that would fit his size 9 feet, but he tried them on anyway.
Ryan was right. The shoes were way too big, although he loved the way they looked on him. He knelt down to take off the shoes, but they couldn't move! He felt his feet tingling, sweating, and... growing? He felt his socks splitting apart as his feet expanded to fit the shoes. The tingling spread up his legs, as dark brown hair was dusted across them and his calves grew out. His thighs grew thick and meaty as the tingling continued upwards. Ryan examined his new legs. His new lean calves and thick thighs had ripped his jeans. What was happening to him? Ryan was worried, but he was starting to get turned on...
Ryan's slightly pudgy stomach sucked in suddenly, causing him to gasp. He lifted his shirt, and was in amazement and lust as his stomach hardened into a solid six pack. He almost fell over as his chest shot out into two meaty pecs, ripping up his shirt. His shoulders squared, destroying what was left of his already ripped shirt. The tingling came to his arms, as dark brown hair pushed out on his arms, and his biceps and forarms expanded out with muscle. His hands, like his feet, grew out gigantically.
"please... stop..." Ryan tried to say, but he was interrupted by his moaning. He was insanely horny, he didn't know why. The tingling continued up his neck, his adam's apple bulging out, causing his moans to drop an octave. His jawline became chiseled, as a short stubble of dark brown hair grew out on his face. Not much, just the stubble of a lazy shaving schedule. Ryan's face cracked as it gained a slavic look, and his hair retracted to a short buzz as it gained a dark brown colour.
Ryan was losing it with lust. He felt his dick tingling, as it grew, and grew, and grew. A forest of dark brown hair shot out above it. Ryan's moaning intensified as what was left of his pants expanded around his new legs. The jean softened into track pants, and white stripes and an adidas logo pushed out. His shirt came together into a black adidas tracktop. He came. Ropes of cum shot out of his new, 7" slavic dick. Memories of his old life, his old personality, exited with the cum. In their place, new memories of growing up in Moscow, his hard life, stealing for food, he and his comrads goofing off, dancing to hardbass.
Sergei exited the store. His comrads are going to love his new shoes.
