Thought I'd treat myself and decided to go with getting a double with some top-level talent.  I'd like to spend about $$$$$$/hour/girl.  Does anybody have any experience with Mona Lisa or any of the upscale agencies for doubles?  I'd really like to make sure I get a true threesome instead of a 2-on-1 (read: they have to be really into each other as well as me, DFK DATY etc).
