SpankWire.com is a free porn site offering a massive library of videos coupled with intuitive design and decent search options. SpankWire focuses on videos from professional porn companies, but the problem is that most of the videos are promotional, lasting only about five or six minutes, sometimes even less.
Still, the navigation bar lets you sort all the videos by their longevity, skipping those unfinished ones. Content type defaults to straight by default, but you can switch it gay or tranny. The video player is decent, even though we had some buffering problems. There are ads and popups, but they are tolerable.
