Jamie looked down once more at his towering younger brother and all he could see were Timmy’s brick-like abdominal muscles and his bulging pecs almost sticking out in his face. Looking just slightly down, he saw Timmy’s enormous cock staring him in the face, literally.
“Uhh, let’s see if we got some large clothes for you in the garage bro!”
Jamie turned around and walked into the garage where they had several plastic bins containing old stuff which the family had saved up over the years. There, Jamie found some old clothing which belonged to his father before he passed away. Jamie took a shirt and some sweatpants out of the bin before returning to Timmy’s room.
“Try these on, bro!” he said as he tossed the clothes to Timmy.
Much to his surprise, Timmy was able to catch the clothes quite easily. Jamie looked up and noticed how, thanks to Timmy’s added height, Timmy’s arms had also grown thicker and longer.
“There, I’m dressed again!” Timmy said, walking up to Jamie.
Jamie had to crane his neck up since he was staring straight into Timmy’s large chest.
“Wear these clothes until we find something else for you to wear and then…” Jamie began, until he was interrupted by an angry rumbling sound which came from deep inside of Timmy’s stomach.
RRRRUMMMBLLEEEEE!!
“Whoa! Somebody’s hungry!” Jamie remarked. “When’s the last time you ate anything, bro?”
“Yesterday!” Timmy shrugged. “Last night!”
“Well, we can’t have you growing like this on an empty stomach! You need some food! We need to feed this big body of yours!”
Jamie then ordered a bunch of sandwiches to be delivered. When the delivery guy came, Jamie answered the door first, when Timmy finally joined him.
“Hi… Uhh… Can I talk to your… Uhh… Is there an adult in the house?” the delivery driver said to Jamie, when Timmy got to the door. With Timmy being much bigger and taller, the delivery driver saw Timmy as the adult in the household. “Here is your order, sir!”
Jamie gave Timmy the money, so Timmy paid him and took the box of sandwiches before closing the door.
“That was funny, bro! The delivery guy thought I was the oldest guy in the house, not you!” Timmy laughed as the boys sat down at the kitchen table.
“I guess I’m gonna have to get used to that!” Jamie sighed.
Setting the table was easy for Timmy, He was now easily able to reach the highest cupboard in the panty and he could get to the top shelf in the kitchen closet without getting on the stepladder, even though Jamie still needed the stepladder to get to the higher shelves.
Jamie only ate half of a foot-long sandwich while Timmy ate a whole foot-long and ten whatever was left of Jamie’s sandwich. He ate everything!
“I bet you’re feeling better now, huh?” Jamie said as Timmy walked up to him when they finished eating their food.
Jamie was about to wipe down the table when Timmy closed his eyes and let out a loud groan.
“Uhhhhhh….” He groaned as he craned his neck backward while Jamie was standing next to him in the kitchen.
“Timmy? TIM? What’s going on? What are you feeling, bro? TIMMY?” Jamie shouted in panic.
Jamie walked right up to Timmy, not knowing what was happening, when suddenly, he saw the changes before his very eyes! Timmy was GROWING!
Timmy’s legs were slowly growing longer, making Timmy stand a few inches taller! As Jamie looked on, he saw his younger brother slowly increase in height as he stood a few inches in front of him. He was little growing in every direction. His arms were getting thicker with raw muscle and his pectorals were pushing outwards and sideways even more so. His abdominal muscles were becoming bigger and wider and deeper, like a wall of bricks.
“UUUUUHHHHHHHHHH!!” Timmy roared, as every muscle in his body exploded out of his frame, all at once while Jamie could only look on, helplessly.
Timmy’s lats and backside expanded even more while his delts and traps expanded and grew bigger and wider. His quads made his legs grow even wider, becoming bigger than the largest tree trunks. His legs were like massive columns of power, jam packed with huge cords or muscles which were completely covered in a network of thick veins all over. Timmy’s legs began to resemble those of an Olympian marathon runner or a cyclist!
Big, thick and wide mounds of muscle formed across Timmy’s shoulders, his arms, his forearms, and his backside as mighty muscles exploded everywhere across the big kid’s body. Nothing was stopping Timmy from Hulking out. Timmy was destined to gain an unprecedented amount of strength and power that only the biggest bodybuilders could relate to. And he was still a young, teenage kid, but with the body of a large, professional athlete!
“Oh man… Uhh… Oh wow…. Wow…. What the heck….” Timmy gasped, breathing heavily.
“TIMMY! Are you okay? TIM!” Jamie screamed.
Suddenly Tim reached down and pulled his sweatpants down. Obviously, the sweats had become much too tight for him, thanks to his latest growth spurt. He was also on the verge of bursting out of the t-shirt Jamie had just given him.
“Ohh… It hurts…. Uhh…. I can’t hold it….” Timmy groaned.
Jamie looked and saw Timmy’s massive 11-inch-long cock. It was rock hard like a sewage pipe! His balls were also bulging. Within seconds, white drops of cum started dripping from the cock tip, and eventually a long stream of salty, thick, creamy white liquid started streaming from Timmy’s massive cock for the very first time.
“WHHOOAAAAAA!! JAMIE! HELP ME!” Timmy roared as he had his first massive orgasm.
“Just HOLD STILL, TIMMY! DON’T MOVE!”
Jamie could only stand there and look on as Jamie shot a stream of cum that hit the wall on the other side of the living room. Timmy stood there for three minutes, before the stream gradually came to an end.
“Oh wow… Oh man… Ohhh what was that… Ohhmygod…”
“You just had an orgasm, big little bro!” Jamie smiled, looking up to his even BIGGER little brother. Jamie was about 5-foot-3 inches tall, but Timmy was clearly past the 6-foot-6-inch mark by now. He was HUGE. “I think I need to look for bigger clothes for you…. Again!”
Jamie looked up at Timmy. He looked up and up and UP. Oh wow, Timmy was big. He was HUGE. And his muscles were incredible. Timmy looked like he was a student in Jamie’s high school! He looked like one of the guys on the football team, with all the size and muscle he had now. Timmy was gigantic compared to Jamie now, standing 15 inches taller and with more than 150 pounds of rock-solid muscle added to his frame. How would Jamie cope with having a massive, little brother in the house?
