Have you ever caught someone peeping on you?

There was one time...a female acquaintance I knew asked if I could give her a ride to someplace she needed to go and I agreed. She showed up at my apartment the morning of the day she wanted to go, earlier than expected, so naturally I wasn't ready yet. I invited her in and she sat down in the living room while I excused myself to go get ready. I was in my bedroom and didn't bother closing the door because it wasn't visible from the area where she was. You know how you get that feeling you're being watched? I turned around and there she was standing in the doorway (I hadn't heard her walk up)...I was completely naked and she didn't say anything, just stared at me for a few moments. I'm a naturist so being seen nude by others is not really all that big of an issue with me, I just casually went about doing what I was doing as if nothing was wrong (and there wasn't). After a couple of minutes, she left and went back to the living room to wait for me. I finished getting ready and we went on our way, and nothing was ever mentioned about that incident. I do not know why she had come back to my bedroom to this day.🤷‍♂️
