Josh just ignored what Ric and Marco were fussing about and decided to have some fun with the book on his own. He had now figured out where all the different spells were and how to use them. He had even memorized a spell or two! He looked around and came back to the section about aging and growth. He knew of the spell to make a person grow older or younger, but somewhere near the end of the section he discovered that there was a chapter about just aging a part of a body as well!
He looked through it and saw a list of ideas, for example he could have an adult body, but still maintain the face and the mind of a kid! He loved the thought of having a part of him being grown up already, and a part of him still be a child. So he looked through the different spells and counter spells, until he got to the section where different spells were listed describing aging for different parts of the human body.
Then Josh got an idea. Being that he was still only 12 years old, making him the shortest and the youngest guy in the house, he longed to have a part of him mature and grow faster than the other guys. He flipped through the pages in the chapter until he finally found the spell which could age his cock. He found the different words to describe the different ages, and each age had a different spell. So he though about it for a while, if he were still 12 years old, how old should his adult cock be? Then he decided to just double his current age, and he picked the verse for growing a 24-year-old adult cock on his 12 year-old preteen body.
Josh got up and stood in the bathroom, while Ric and Marco were still arguing. They were too busy to notice him, as usual. So Josh decided he was going to have some fun with the book on his own. He pulled his shorts and his underwear down, and he admired his tiny 4-inch kid cock in the mirror. “Time to try an adult cock for a change” he whispered. At the last minute he decided to go for 30 years old, instead of 24. He saw the verse which would make his entire body age to 30, but he didn’t want that. “I just want my cock to grow up” he said to himself. Then he located his spell and spoke the words slowly and clearly.
A wave of pleasure came over him, as he stood in front of the bathroom mirror. His little 4-inch meat became over an inch thick and began to grow longer! It stretched to 5 inches, 6, and 7… When it was 8 inches long and 1.5 inches thick, it stopped growing. Josh couldn’t believe it! “Whooohooo!” he shouted out loud. Ric and Marco came over to look and they were astonished when they saw their little brother with his giant member. “I got an eight inch cock and I’m only twelve years old!! Awesome!!!” Josh cheered out loud. Ric and Marco could only stare in disbelief at the 12 year-old boy with the large, adult-sized 8 inch cock. “Oh yeah! I’m keeping this baby!!” Josh shouted out loud.
Both Ric and Marco looked down at their own endowments and bowed their heads in shame when they realized that the little boy had the biggest cock in the house…
