Seeing that his brother was OK, Jamie decided to go digging for clothes for his brother again before his little brother called out to him again.
"B-bro! It's happening again!" Timmy yelled out, his voice trembling with fear.
Hearing Timmy's cry for help, Jamie quickly made his way back to his brother's room. As he entered, he was met with the sight of his brother's body changing once again. This time, the sound of bones cracking and skin stretching filled the room as Timmy's arms and legs began to stretch out, and his head rose higher above Jamie's.
Jamie's eyes widened as he saw Timmy's arms begin to balloon outward, developing massive biceps that were as large as Jamie's thighs, even when they were unflexed. The sight was both awe-inspiring and terrifying, as Jamie couldn't help but feel a mix of emotions as he watched his little brother's transformation.
"How is this possible?" Jamie thought to himself, unable to take his eyes off of Timmy's growing muscles.
Jamie watched in awe as Timmy's transformation continued. His chest and shoulders expanded to an unprecedented size, and his back muscles became even more defined. Jamie couldn't believe what he was seeing. The once “little” brother in front of him was now developing the physique of a professional bodybuilder.
Timmy's biceps and triceps grew larger and more defined, and his forearms became thick and powerful. His abs were now a wall of muscle, and his obliques were sharp and chiseled. Jamie's eyes were drawn to Timmy's legs, which had become massive tree trunks of muscle.
As the transformation came to an end, Timmy stood at a towering seven feet tall. Jamie found himself eye level with Timmy's massive, bulging pecs, which pushed far out from his chest. Jamie couldn't help but feel small and insignificant in comparison to his younger brother's newfound size and strength.
Jamie couldn't believe what he was seeing as he looked down at his brother's waist. Timmy's massive dick had grown another inch, making it a full 12 inches long, and the girth was so large that it would be a challenge for most people to handle. His balls had also grown significantly in size, becoming round and almost doubling in size.
"UUUUUHHHHHHHHHH!!!" Timmy roared, as another orgasm took over his body. This time, it was even more intense than the first, and he shot twice the amount of cum out, the force of which caused it to arch across the room and hit the wall with even greater force than before.
Jamie watched in amazement as his little brother's body continued to change and grow in ways he never thought possible. He couldn't help but feel a mix of emotions - fear, awe, and even a little bit of jealousy. He had always been the older brother, the one who was supposed to protect and take care of Timmy, but now the roles had reversed.
Despite his initial shock, Jamie couldn't help but feel a sense of pride. Despite the initial shock that coursed through him, Jamie found himself enveloped in an unexpected wave of pride. As he watched his younger brother embark on a transformative journey to achieve a physique that had always seemed like a distant dream to him, Jamie felt a peculiar sense of connection. It was as if he were living vicariously through his brother's experiences, relishing his transformation as if they were his own.
"Wow, Timmy," Jamie exclaimed, his voice brimming with awe. "You look... absolutely incredible."
Timmy glanced down at his newly sculpted physique, a small smile blossoming on his face as he took in the reflection of his hard work. "Thanks, Jamie," he replied, a hint of pride in his voice. "I feel... different. Stronger, I guess."
Jamie nodded, still captivated by the transformation before him. "You are, Timmy. You're going to be unstoppable. I can’t believe how far you’ve come."
Timmy's smile widened, and he took a moment to soak in his brother's words. "Thanks. Um, Jamie," he said, his tone shifting to something more heartfelt, "I just wanted to let you know that no matter how big I get, you’ll always be my big brother."
With that, Timmy effortlessly scooped Jamie up as if he were a feather, lifting him off the ground and enveloping him in a warm, powerful hug. Jamie found himself pressed against Timmy's massive chest, the sheer strength radiating from his brother both comforting and overwhelming.
As he laughed, enveloped in the warmth of their bond, Jamie came to a profound realization: no matter how much Timmy transformed on the outside, the love and support they shared would remain steadfast and unshakeable. He felt a deep sense of relief knowing that, despite the physical changes, Timmy's core personality remained unchanged. The same kindness, humor, and determination that had always defined his brother were still very much intact, grounding their relationship in a way that transcended appearances.
