Billy entered the house after a long and boring day at school. Feeling dirty from football practice, he decided to go and take a nice long, hot bath. He entered the bathroom and removed all of his clothes. He turned the water on in the bathtub and while he waited for it to fill, he looked at himself in the full-length mirror. He had a well worked on body with a six-pack to drive any girl crazy. He had short brown hair, blue eyes and a small mustache growing in nicely.

He crawled into the tub as it got to the height where he liked it and shut it off. He laid his head back and enjoyed stretching out in the six-foot long tub. He rested his head back against the plastic pillow he had in there and closed his eyes. He awoke some time later to someone pounding on the door that they had to pee so he reached over and unlocked it. After pulling the curtain closed, he yelled they could come in. He looked through the little crack left between the wall and the curtain and noticed his sister sit down on the toilet.

His sister (Kim) was nineteen at the time and looked great to Billy. If she hadn’t been his sister he would have fucked her as soon as he hit puberty. He did not think that she could see his little eye peeking through so he kept it up. She kept moving her legs apart then together which gave him a perfect view of her shaved pussy. He got hard right away seeing this and felt his cock stir. He reached down and slightly stroked it trying not to make any splashing noises.

She got up, whipped herself and thanked him before leaving.
