www.darering.com isn't a bad site. It's evolved in the pas year or two. Used to be just a couple of videos (although they were quite long, over an hour each I believe. But now there's 17 plus a few bonus one. I'm not sure of the length - you used to be able to download full length segments for free up until the nudity portion, and then paid I think $3 or so for unlimited to the nude portions. Now they charge $19.95 for a month of access to everything, but the free segments are very very short (less than a minute). They started out with a couple of guys who sometimes (although infrequently) did guy-on-guy stuff, but it looks like most of them now are either all girls or just one guy. By the end of each game it looks like things get quite hot between the contestants.
Hope that helps.
