It takes some work.
1) create fet profile -- label yourself a voyeur, not a dom -- less threatening
2) make at least ~50 connections so you don't come across as a bot or serial killer
3) join chat groups: see attached
4) search for upcoming gangbangs, bukkakes, and sex parties under EVENTS, focus on those hosted by the gb slut herself
5) mark that you're "going"
6) ask host a question about party (logistics or what kind of bottle you should take)
7) say you can't make it as you were pulled away for a work trip (do so before event), then change your rsvp from going to not going
8) ~48 hours after party, message her and ask how it was, you're so bummed you couldn't join
9) let her know you're back in town, and when's the next one. Ask if you can invite your college buddies. Append, by the way I'm always able to host a private session before then in (ritzy part of town. Georgetown works best. Arlington if the girl is in VA. Bethesda if MD). Let her know you're happy to cover her "ubers, etc" (indicates a willingness to make a tribute, but not at escort prices)
Power formula --
20 parties a month, 10 hosted by chicks, 4 of them 6s or aboves, 1-2 wins a month
Many of these girls are college edumacated and don't want to think of themselves as ho's so this provides them cover
Good luck!
