Adult One-Way Incoming Link Building 3

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. Real links, not redirects. Only links from pages indexed (cached) by Google within the last two months will be accepted. e.g. no links from orphaned pages. 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.
