Petra. The name means “rock” and you’ll understand why when you see Petra Quednau’s naked knockers and nookie as she’s penetrated with a hell-spawned creature’s green phallic tentacle in the German sex-horror masterpiece Dämonenbrut (2000). But before she became a demon-semen receptacle, Petra was hardening parts in the porn-crime flick Der Todesengel (1998), a.k.a. Angel of Death: Fuck or Die. If we have a choice and Petra is involved, we’ll take the former, please.
