Looking for old series

[BoobLoverJoshua]

So I remember reading a series many years ago. The main thing about the series is that the main character was a porn star who was the founder of an organization of women who would fuck anyone (man or woman) who asked them. They had an acronym that I'm /pretty sure/ was S.L.U.T but I'm not positive, and using Google to look doesn't work as it doesn't seem to count acronyms any different (so searching for "S.L.U.T." just returns results with "slut").

Does this click in anyone's minds?
