Wats the name of this show or video?

A while back i seen a Show or Movie don't really remember what it was but it was about a bunch of girls naked most of the time that teached you how to do things. One of the girls had a huge tattoo on her back that was cheetah printed. Other ones had tattoos all over their bodies. they teach you how to fake s. and other stuff. I wanted to show this video to a friend of mines but don remember what its called. does anybody know?
