Jamie woke up that day, feeling better than ever. He examined his beautiful, strong body with every inch of perspective. As he went up to check up on Timmy, he gave him a short hug. Jamie din't think much of it at first, but later on Timmy started to feel weird inside.
"Brother, I feel really hot, but cold at the same time." he said quietly. "Are you sick?, don't worry I'll go get some water for you."
After Jamie left, things started to change for Jimmy. He slowly grew taller, and his penis grew a inch longer. Once Jamie came back, he din't notice the changes. Jamie went to get medicine for his brother which is all the way down in the basement. When he left, Timmy's body began increasing in mass. His bicep's grew to 16 inchs, his stomach hardened and 6 little blocks of muscles began to form. His legs were beefing up with little muscles and he grew even taller. His dick was expanding at a alarming rate, he was growing almost as strong and as tall as his brother. His bicep's finally grew to 18 inchs, alongside with a deep cut 6 pack abs with 2 more forming that was less visible, his shoulders grew to thick boulders which were covered in veins. His calves and quads started to push against his little pajamas he was wearing and slowly tearing apart the materials. His pants ripped and his knees formed a similar tear drop shape as his brother. His back expanded in a perfect V shape any man would envy. And his dick was increasing in size further and further and bigger and bigger through his change. Jamie heard ripping sounds and he was worried as he rushed into his room to find a "huge" surprise
