Adult One-Way Incoming Link Building 2

I need 20 (twenty) Adult One-Way incoming Links for an ADULT WEBCAM AFFILIATE site. The current site is PR4 (four) with several PR3, lots of PR2 and PR1 pages, but does not have a lot of content. NO links from FFA, banned sites, Google banned (not cached) sites, guestbooks, forums, pages with >100 outgoing links, etc. Only links from sites indexed (cached) by Google will be accepted. Three way links are ok. E.g. where I have to link to some OTHER site - not the same site that is linking to me. But the two sites should not be related; e.g. not on the same server, class C ip, or with the same whois information. (Note, this is an additional project, for another site, than previously listed projects)
