Being seen naked by young neighbor

It was a time when I was single, and the only visitors I expected were ladies that were lovers, I would shower with the door open, and where I lived it was common to leave the house doors open in the humid summers. So I was showering one day and got into jacking off, and I really gave into the urge, and took my time. When I finished I saw the neighbors 11 year old daughter standing in the hall way watching. She didn't turn away or run, or look embarrassed from the view she got through my anti fog glazed glass shower door. All she had was a little smile like she had enjoyed watching. We never talked about it, and it didn't change how we got along, she like to putter and keep my yard tidy around s**ttered works of art, she took the occasional drawing lessons from me. She never flirted, and I regarded her as a charming c***d, aside from her seeing me jack off our relations were very proper. She had seen books on drawing nudes, and she was keen on drawing the human body but for coming up with fashions rather than titillation, she liked drawing the figures of friends and family. I got to know about all their boobs as she learned how to draw them. The most risque thing she ever asked me is common and timeless from young girls..what will I look like with bigger breast, and asking their art teacher to help guess. There are sections in the manuals by age so you can get the proportions right, and the changes of adolescence, like girls developing breast...all very analytical in the book but a bit different when the young girl is going into the details and has a sketch pad. I was glad she didn't draw herself with big Barbbie boobs, it was a little uncomfortable seeing near nude sketches of her self in her bedroom mirror. She drew pictures of her mom, and her very pert boobs. She did drawings of her friends that were maturing, and would make fun of them, but was jealous at the same time. She dreamed of fancy clothes. but was very relaxed about how she looked She would show up in hand me down swim suits that were a little small for her, and worn thin when they played in the lawn sprinklers, so I knew her outline pretty much as she knew of mine. We talked about drawing nudes, but nothing sexual out side of physical shape. She ask about what it was like for models that pose nude for classes to sketch, what it was like to go to school to draw naked ladies.
