i'm not sure exactly what i was expecting, but this was not it. to me anal, atm, and rimming don't live up to the phrase "the filthiest". those who like high heels or pvc may find it interesting, but that's about it.
This movie was ok. We were expecting a litle more from it, but it wasn't terrible. Worth the rental if you aren't expecting too much in the way or over the top scenes.
