This video is more explicit than anything else I've posted here. The first one takes out the most explicit bits, and the second one leaves them in. This video has both boy/girl and girl/girl porn scenes. If the link is dead, try a Google video search for the uncensored version. Laura Andresan is a pornstar as well as a singer, but as far as I can tell she seems to be better known for this video than for any porn she's done.
This website currently has the uncensored version. Unlike most of what gets called that in the music video world, this one actually IS an explicit porn video.
