Follow the yellow brick road to PrettyPissers.com and you'll find full-length downloadable videos of amateur gals letting loose a river of urine for their male friends. Don't expect the fetish to last long in the movies though, since a greater focus in the content is hardcore sex. There's not a lot to be had on the site, but if you're into other fetishes like fisting or BDSM, then you'll get off on the bonus content.
