As much as I detest so-called "porn parodies", namely the endless series of 21st Century Adult videos that rip off intellectual property from the world of mainstream movies & television under cover of "free speech", this prehistoric example is amusing enough to warrant viewing. It's the work of Herschel Savage, who never seriously pursued a directing career (likely tired out after thousands of on-screen XXX roles) and the untalented "writer" Cash Markman. Markman is infamous for having so many scripts actually shot, albeit merely as video porn, never legit movie-making, so even the rare success like this one still doesn't raise his batting average above roughly .010.
The acting is way above average for porn, and the gags clever. As far as sex is concerned, I enjoyed ultra-buxom Charisma guest starring as Cousin Tit, most impressive in a lesbian incest scene with Kim Angeli in the teen "Tuesday" daughter role. These actors, particularly Mike Horner and Ona Zee as the iconic parents, take their work seriously, and it helps to shoe-horn into the story the great Deidre Holland.
