Jamie watched in astonishment as Timmy devoured his breakfast. Timmy was in nothing but his briefs and socks he watched his seven year old brother devour strip after strip of bacon. Little did Jamie know the more protein Timmy ate the bigger he would get.. At first Timmy's biceps started to inflate slowly from a meager ten inches to a massive fifteen inches. Timmy started to moan as he underwent the changes his arms were thickening and his chest began to grow as well. Soon Timmy's feet started to grow and eventually reached the ground his legs started to inflate too. Soon Timmy reached for Jamie's plate and began to devour all of the food on his plate. Jamie was at lost for words as he watched his little brother grow from 5 feet tall to 5 feet 5 inches all the while Timmy was getting stronger and stronger. When Timmy finally finished both of their breakfasts he stood up and noticed he was almost as tall as Jamie who only stood at 5'9". Jamie's eyes lowered and noticed that Timmy's bulge had also grown and now Timmy's briefs were straining to contain it.
