We were visiting a clothing optional hot spring and I was changing in the parking area for the short walk into the forest. There were several other groups getting ready also. I was strapping on my sandals and only in my panties when a couple of teens began staring at me bug-eyed. I just smiled and went about my task of getting ready when I heard one say: “Quit staring, it’s not polite.”
Later I wondered if they were staring because of the panties, or because of my bare breasts. Either way I took it as a compliment.
