If we are talking about shaving pussy then
Dalene Kurtis is the first to shave completly. But if we are talking about labia display then
Patti McGuire is probably one of the first to show her lips.
There are some great pictures where pl@ym@tes shows her labia.
I remember an amazing picture of
Laurie Jo Wood where she shows her pouty labia in a full frontal view. If You like labia You must see that picture!
I also remember that
Karen Elaine Price (one of my top pl@ym@tes) have some pussy view pictures but unfortunately her muff is so thick that her lips remained hidden to our eyes. That's a one big lost!
