Candid upskirt panties at a park
A nice warm day for this shot of candid upskirt panties at a park on the grass.

Just a pic of a (probably) hot young blonde taking a break for a rest on the grass, and showing her sexy black panties to everyone who walks past. And what is that mark I can see on her panties? Is that what I think it is? I can only hope I’m right, and you can feel free to make up your own story about what is going on down there.
