She had always been skinny, which was unusual for girls as short as she was.But after she hit her peak height, the rest of her seemed to start filling out just right.They were humping each other when I walked in, and they turned their heads when they heard me.
In fact, I was pretty sure that me and dad were the only guys she had ever seen naked.
Along with the nudity, our family had always been into mutual bathing.
She had the greatest ass, and fairly generous breasts.
In that way, along with her good looks, she took after our mother.
We didn't have a giant bathtub that we all got into together, but it wasn't uncommon for my sister to ask me to wash her hair for her, or for mom and dad to take a bath together. Over time, mom and dad became more open with their affection.
