VPL=Visible Panty Line
And when you don't see the vpl, it means she's wearing a thong or
g-string. So I think you guys got it all wrong.
It's not visible thong line, for pete's sake.
And I cannot stand girls with super obvious VPL. EWW.. Definitely
turn off! But I LOVE girls wearing g-strings or thongs, and you can
see their full ass through that tight piece of bottom.
