This site has been linked before in the Free Sites section but for those that missed it: altitude.net.nz/photos/
They have been new adding photos lately, but not a lot of game/contest content. You can find a few wet t-shirt sets there, jelly wrestling and some other random shots. They used to have other photos before they changed the site layout, for reason they got rid of all their old photos.
Below is a link with some older photos I had collected before they deleted them. The best set out of the bunch is probably "Strip Musical Chairs 1" and a few of the "MISC" photos are pretty good also.
