Caught Naked By My Aunt
Well, the story is simple. I was alone in my house and I decided to take a shower before I leave for my work. When I was in the bathroom my mother returned to the house with my aunt, who had informed us before that she was planning to visit us.
Unfortunately, the first thing my aunt wanted to do was to use the toilet and as she didn't know I was there she came in without knocking the door. Of course she got shocked when she saw me in and she left saying "sorry" to me and my mother.
When I finished my shower, my aunt (a good looking widow, despite her age - 63 at the time) apologized for the accident and assured me that she didn't see anything. Although I am quite sure that she saw everything, as the door is very close to the bathtub and I was uncovered (if she saw, she must have seen my **** too!), I acted like nothing happened and the story ended.
