This is the sort of fare that plays best on some late night cable station, retitled "The Erotic Awakening of X."  Yes, it's horribly dubbed (but not into English).  Yes, the women resemble men, and the men resemble members of a mid-'80s East German rock group.  And yes, the action is lackluster.  Porno X-Treme, Vol. 4 is anything but, but it should provide laughs, as well as some insight into why there are so few supermodels from Deutschland.
