Director Jack Genero does the most that can be expected on a small budget and comes out with a good effort in one of these tapes. But the main perversion concerning the pseudo-documentary Perversion is that Gina Valentino, the sultry, dark brunette who narrates and appears on the box cover, does no hardcore.

Fortunately, after we get a history of perverse sex told to us, with asides to Kinsey and Webster's Dictionary, we get an array of vignettes featuring anal sex, double penetration, transsexual sex featuring Oriental she-male Nikko Micki, lesbians and Ron Jeremy doing himself. And let's not forget midget Louis Shortstuff. No bondage here, but this stuff is recommended only for the adventurous.

The four segments of Penetration 4 contain only the most standard sexual action, with the exception of Summer Rose and Ron Jeremy doing it anally at the end. Each segment drags into oblivion, and I must admit that I could not help speed-searching at times. Although there's an O.K. lesbian shower scene, most of this tape is indistinguishable from any other shot-on-video material I've seen lately.
