Mikey held his stomach slowly moving his hands down to his tiny little one inch penis as he can feel it stir in his tight spiderman undies. a pulse rushes through his body as he can feel it reel out from him like a fire hose! "Daddy! my peepee feels weird!" Mikey stammered as he waddled forward Eric told his five year old son to sit down with a panic in his voice as he can see the bulge grow in Mikey's pajamas.
Two inches, Three Inches, Five Inches, Six inches. Within only a minute Mikey's little penis grow to be a cock that would surpass his own father's, and it showed no signs of stopping. At this point Mikey's balls started to grow, from the size of tiny Marbles, to Grapes, and then to Eggs, the boy's nuts looked massive on him.

It was thick with large veins pulsing the cock making it bob up and down. Mikey, excited to see his new gift, said "Look Daddy! I think it's bigger than yours!" as he swung his hefty cock from side to side.
"Ye..yes son, it really is..."
