With one hand scratching his chest, and the other hand scratching his pit, Ty felt his small, undersized cock slowly fill up with blood. Pretty soon, his small penis was tenting his boxers. He looked down, shocked, and notice something. His erection was tenting his boxers much farther than before. He quickly glanced in his boxers again and saw he was indeed growing bigger! His cock was at least an inch longer now, and there was more hair! He snapped his wasteband shut and grinned at the realization he was about to have a much bigger dick.
He looked down again and saw some thick brown pubes crawling up above his wasteband. They made a small trail of thick hairs from his crotch up to his belly button. He was growing a happy trail! It was really dark and thick; you could probably see it from pretty far away! The trail was slowly expanding past his belly button, and more hair was spreading out on his stomach. Staring at his new trail of hair, his hand lazily drifted under his arm and scratched. That was when he felt something unfamiliar. He lifted up his arm and gasped. He was growing hair in his armpits! Not much hair, maybe 10 or 15 hairs, and they were thin and wispy. But he had pit hair. Dustin saw his brothers surprise and laughed. "Ha, you call that pit hair? Maybe by the end of it you'll have pits like mine!", He said. Dustin lifted up his arm to show off his massive thatch of thick brown armpit hair. Ty gasped, thinking he might have that much hair under his arms, and soon!
He heard something crack and felt a pain in his feet. He looked down and saw his feet looked bigger. A lot bigger! They were visibly growing in front of him! They made cracking noises as his toes stretched out farther and his feet lengthened and widened. They finally stopped growing at around a massive size 14 or 15! He lifted his feet and stepped experimentally. Jeez they were so much bigger and heavier! He then saw dark brown hair growing rapidly all over the tops of them! Even the knuckles of his toes became dusted in hair! By the time it was done, his massive feet were very hairy! That was when a nasty scent hit both his and Dustin's nose. Oh god, his new feet reeked! It smelled like sweaty locker room feet.
"Oh man, Bigfoot, your new feet reek dude! Gross! And I think they are even bigger and hairier than mine!", Dustin said, putting his large feet next to Ty's to compare. To his shock, Ty's feet were indeed hairier, larger and much to his embarrassed, much smellier! Ty blushed red; "sorry Dustin, I can't control how these smell!".
By now Ty was noticeably taller, stretching up and up. He felt a lot heavier as well. He could feel his small frame slowly but surely packing on tons and tons of muscles! He could see that his arms, likewise, were packing on some muscles. His biceps in particular looked a lot bigger, more like a teenagers. He flexed experimentally and, sure enough, his bicep popped up a bit! That was when he saw his armpits had sprouted even more hair! It wasn't a massive bush like Dustin's, but looked like what he had seen on the average high school dude!
He felt his abs contract and saw a small 4 pack pushing through. He could also see the thick trail of brown hair coming up from his boxers and going up to his belly button and higher. It was much thicker and wider than before! The hairs didn't look like it was going to stop, and would keep growing up his torso. He could also see his pecs slowly growing larger and thicker. A handful of brown hairs had started to grow out from around his nipples. Ty was astonished! He was starting to get a bit of chest hair!
Ty felt his crotch feeling very tight. He looked down and it looked like his boxers had shrunk considerably on him! They were practically hugging his crotch! "They didn't get smaller", he thought, "my cock and balls have just gotten bigger!". Ty grinned at the thought of having bigger junk. He quickly slid the boxers down his hairy legs, letting his new cock flop out. It was now about 5 inches long soft and quite thick, hanging down below his fat and hairy balls. His pubes had turned into a real bushy nest of hair, almost as much as Dustin's! "Damn dude, your cock is plumping up nicely! Not as big as mine though!", Dustin said.
"We'll see who's bigger at the end of this", Ty said with a grin. Except it wasn't his voice that came out, it was so much deeper and more masculine than before! Tys hands flew up to his neck and he was greeted to a huge protruding Adams apple sticking out of his neck!
Ty was nearing 6 feet and his body was still packing on the pounds of thick muscle! He could see his chest hair coming in thicker and longer, becoming something more than the average guy would have. Flexing a bicep, he saw it pump up, nice and beefy and veiny! A flash of dark caught him in the corner of the eye, and he lifted his arm to see. His armpit hair and filled in considerably! He might even have more than Dustin at this point! "Lift up your arms, Ty!, Dustin commanded. Ty did as he was told, letting the huge sweaty bush of armpit hair spill out. A wave of nasty BO washed out from the pits. "Fuck, Ty, your going to be one stinky dude! You reek, man! First your feet, and now this?!". Ty blushed a deep red, which was even noticeable through the thick sandpaper stubble that had bloomed on his face. Ty liked all these changes, but he for sure didn't want to stink!
Ty was reaching Dustin's height of 6.5, and it seemed the growth was slowing down. His body felt a lot heavier, and it was still packing on the pounds of muscle! Ty was sweating and breathing heavily from the changes, his large hairy pecs going in and out with his breath. The room quickly filled with the stink of two hairy, sweaty, testosterone fueled football machines! Ty lifted up a beefy arm and sniffed. It made his dick twitch, and he admitted to himself his stink smelled good!
As the changes stopped, Ty looked down and saw his cock had grown again! Soft, it was hanging down heavily and thick, about 9 inches long. He also had huge balls, too! "Oh wow", he said in a deep voice as he cupped his hairy, musky nuts.
Ty stared at himself in the mirror, absolutely stunned. He looked like Dustin now! Huge, hairy, hung! Ty was speechless!
