He shrinks back for now

John takes another look in the mirror, enjoying how well he looks with a massive cock. But he knew that today is PE day, and he figured that him having a huge dick, would be great, amazing even, and he knew that he could make a lot of the guys green with envy, but he didn't wnat to just have it, right there and than. At least not now, he wanted to do it in a fun way, maybe even "steal" some dick from the other boys?
He takes a last look at it, feels it in his hands and lets it shrink down to his original size, he puts on his pants and leaves his home.
