Adult Sample Video Source

I am working on a site idea in the adult niche that will require that I have a large-ish number of the 'sample' videos adult sites give out before their pay-wall. A wide variety of niches (fetishes?) would be nice. Does anybody know of a source for these things? It would be preferable that I can stream them from where they already are in lieu of hosting them myself.

Are you looking for something like that ?

If so, you could find more googling adult content providers with FHG samples, FHG feeds, FHG Galleries, MGP, and all the variants.

These will be a good start. Thank you, sir!
