Mistress Sandra and Mistress Perversity (not their real names, I suspect) are 2 "rubber-inspired" dominas, soever that means. In this film, we watch the duet teach their slaves to become elementary rubber objects whose merely purpose is to satisfy the way-out craves of their latex-clad tormentresses. The director of the film brings us throughout several events which build upon a common philosphical theme throughout out the story. In four separate scenarios, the rubber slaves are submitted to various tortures and rituals according to the unspeakable whims of their captors. However, the viewer will wonder whether those "slaves" are indeed compulsory into those actions against their will - or whether thay are simply servile beings who have a fun this activity. The director of this film cleverly withholds the answer, leaving the audience to ponder lengthy after leaving the theater. Whether fixed motionless in the vacuum couch for hours, or pain lengthy sessions animal play the hands of the Heavy Rubber Nurse or experiencing a the Schnüffelpenis (any german speakers out there? - I could not discover this word in my high school german dictionary) those gagged and tied objects pretty soon learn the way-out rubber craving of their mistresses.
