Sasha Grey is a very pretty girl...with a very filthy mouth. We've often wondered where her dirty thoughts come from—and, um, if she'd be able to give us a few pointers.

As luck would have it, Sasha was more than willing to sit down with us and offer some insight on what motivates her to say such filthy things—and what civilians like us should know before calling a partner a filthy, worthless gutterwhore. Click through the gallery to see what Sasha had to say (and to hear some examples of her mouth at work).
