What has quickly become one of the best all-anal series around returns with a fourth volume of six sphincter-stretchin' scenes.

While every sequence has at least some steamy pleasures, director Sean Michaels saves the best for last, a nasty three-way in which a pretty, hot-wired Budapest babe gets nailed in a d.p. by Michaels and some Euro-stud.

Other highlights include the pale white bum of a blue-eyed blond Brit being invaded by the dark chocolate tool of another black woodsman, and Michaels probing the Hershey Highways of tow other Hungarian cuties.

One criticism though: Some of the action tends to be a bit on the laid-back side and Michaels, therefore, could stand to kick up the energy level a notch or two.
