John's Embarrassing Adventure

John was a teenage male who lived in a typical sub-urban American home. He wasn't particulary muscular, or scrawny, just your average blonde boy. He lived with his twin sister Charlotte and his mom.

One day, while out for a walk, he found a mystical book which fell from the cosmos above him. Opening it, he saw the first page.

"I, the wizard Merlin, who once assisted the mighty King Arthur, have long since died. My spirit has crafted this book. Those in write in it may change reality however they wish."

John felt his penis start to get erect. It was average sized, a good six inches when erect, but he always wished it was smaller. He loved the idea of being humiliated, and this was but one way he could humiliate himself with his new power.
