Astronuts

We're not really sure we want to think about our balls being blasted into space while we're looking at porn, but Astronuts' collection of hot amateur photos (many of which we've seen floating around the web since the 90s, though we suppose it's nice to have them all in one place) is helping us reach liftoff in more ways than one. (We're also happy to see the links in their "Do-Gooder" section to sites like Amnesty International and GLAAD ... because if there's anything hotter than a nicely designed free porn site, it's a socially responsible free porn site.)
