In this import, double usually refers to 2-on-1 sexual couplings that include d.p., d.f. (dual facial), and other abbreviated terms that make reviews sound like classified sex ads.  A lonely housewife theme connects the scenes.  Most memorable is a kitchen counter scene with two gals sharing a double-headed dildo and a Trixie Tyler lookalike getting it abruptly in the rear by Don Fernando.  Those familiar with adult foreign fare should have no problem enjoying this one!
