Click on a title to bring up the description, and, if there's a sampler video you can download it. Most of the titles don't have a sampler, but the ones that do are about a minute, and they show a decent amount (just enough to make you want to see more). The samplers are .MOV (quicktime), and downloadable.
They specialize in public nudity videos (Mardi Gras, flashing, spring break, etc). I've ordered two of their Nude in Public videos some years back, and they're very good. I'd recommend them if you're into that. (P.S.: No, I don't work for them).
