He was on the floor of Luke's bathroom. When he got up, he saw his face. It was smooth like the rest of his body. He looked down and his chest and legs were smooth too. He checked inside of his diaper, and saw that his baby dick as smooth and tiny.
He went out of the bathroom and he saw his room, it looked like Luke's room but it was also mine. That is when a door opened.
A guy around my age walked in. He was way taller than me.
"Hey bud, you need me to change you" he asked.
"Luke make sure your brother wears his training pants." His mother told him.
Luke changed his diaper and he was on the bed naked.
"Let me find your super duper new undies. Ah, here they are." He said.
"Now these undies could only be worn by big kids. They give you magical powers." He told me.
I knew they were just underwear but I felt amazed. Luke saw how big I was smiling. He gave me the underwear and I tried them on.
"Every superhero needs a cape and a super suit." He told me.
He looked in the closet and I saw the undies had superman on them. Luke pulled out a long piece of red cloth and a shirt with the superman logo. He had put it on me and he said I was super boy.
He picked me up and held me flat on his hands. He made wind sounds to make it seem I was flying.
"Who knew Jake was a good older brother." He thought to myslef.
The necklace was very hot and he took it off. That is when everything changed. He got bigger and he was in the same outfit. When he was fully grown, was back back to normal.
Luke was walking down the hall in the same outfit. He picked him up and made wind sounds to let Luke think he was flying.
Later that day. The necklace was thrown into a creek so no one could experience that ever again.
