Back in the 70's I got many opportunities to see panties, and it appeared the women really didn't care.
Of late, things have been very different, and not much fun. However, one day a while back, I was in an office, as a visitor, and there was a nice looking lady across from me. Do to the way things were arranged, I had a lovely view of her, including her beautiful legs. Next thing I know, she has crossed her legs like a guy does, not lady like. I had a great view of her panties and I am sure she did it on purpose, since she was looking straight at me sometimes. This went on for many minutes before she shifted position.
I really wanted to talk with her, but had no way to pull it off. Probably why she felt she could flash me safely.
Things like this keep my 71 year old heart beating
