There's no such thing as a careless woman: if you saw her panties, it's because she wanted to. If she showed off for you, it's because she wanted to. Of course, this isn't an invitation. She can do it. Enjoy the beautiful body she knows she has. Every hot woman knows she is, no matter how low her self-esteem. So, appreciate it from afar. And let her enjoy herself. After all, without a man, who would she show off for?
