You are fucked w/o releases. Expect anything you put on the net to wind up on the screen of the person involved.

Upload the vids to a file sharing site. Post ads on craigslist, posing as a chick in need that is willing to sell her sex tape to anyone willing to PayPal her $25.

PM me clips of the vids for handing you a stellar idea and so I can judge the quality.
