The twelve year old Tommy was swimming underwater in at the pool. He enjoyed swimming and testing his lung capacity to it's fullest. Suddenly something heavy hit his back as he swam. He turned around and grabbed it before it reach the bottom of the pool. He realized it was a book as he grabbed it he was startled. The book felt dry despite him being underwater. He was curious how this could be and quickly swam to the other side of the pool after holding his breath shortly he pocked his head out of the water, looked around and then went to his bag and stuffed the book in. Looking around once more to see if he was not seen. The others which he went to the pool with had already left but didn't forget to inform him that they were going. They always called him a waterrat jokingly. Them leaving didn't matter as they had gone in a group on bicycles anyway and he was used to it. Sometimes he even went to the pool himself since he lived close by anyway. He looked at the book in his back shortly and felt uncomfortable holding it in public as it's design stood out a little too much. If the owners noticed him having it they might get angry and Tommy didn't want that.
Tommy grabbed his bag and after a quick rinse at the showers went into a dressing cabin. Closing the door behind him he took out the book. He opened it and to his surprise the book was full of graphs of peoples names with ages, measurements, hair colour basically everything. It was a page a person. He looked through a few peoples information but eventually he felt discomfort as he felt his full bladder He then noticed his own name, much to his surprise. He hadn't told anyone his measurements like this, he thought to himself. He then read that his body type was ''trim, lightly musculature.'' He smiled to himself because of that. He took good care of his body and all the swimming made it so that while he wasn't buff his muscles very were well defined for his age with no excess fat surrounding them. He was a bit disappointed at his height but it was probably accurate. He then glanced at his penis size. He became red as he read that his penis was 1.5 inches currently. He covered it with his hand and then decided he didn't want anyone to read this. He grabbed a pen out of his bag and wrote a 1 in front of 1.5 inches turning it into 11.5 inches. Suddenly he felt his crotch moving, his swimwear suddenly changed design and colour. He grabbed the elastic and pulled it forward. In his swimming trunks there was now a coiled up 11.5 inch flaccid penis. Tommy suddenly felt a burning sensation and without thinking ran to the toilet. At a urinal he His head hung too low for the urinal so he had to lift it up. He felt the pressure in his shaft while he urinated. Beside him another man was doing his duty and glanced at his penis.
"Holy shit, that's a long penis." Harold thought to himself as he looked at Tommy's penis. "I think I got him beat in girth, though." Harold looked down at his own appendage as he thought that. "Yeah, definitely..."
