Wrong community, this is just coming off not ankles

While “anklepanties” is the short/URL-friendly name of the community, the more important bit is the expanded name (“Panties Coming Off”), and the description on the sidebar:

The perfect shot is panties all the way down around her ankles, but anywhere along her legs or feet (around her knees, her thighs, hanging off her toes, etc.) are all welcome!
