Shauna Grant peeps dad Paul Thomas getting it on with stepmom Janey Robbins between-the-tits, cowgirl, spoon and doggie, and it's soon clear Shauna has the hots for him, since she keeps imagining him in every sexual encounter she sees - and she sees plenty of them. But be aware, all is not as it seems before the "surprise" climax.
In the meantime, look for some decent action between Shauna's cute friend Susan Wilde and photog Billy Dee, which includes reverse cowgirl, doggie and mish - and Shauna substituting herself and P.T. into the action at points - and finally, the inevitable Grant/Thomas cowgirl/doggie bed bounce.
This film offers up some high production values, but sadly, occasional sound dropouts and the failure of the sex to get much above room temperature keeps this from scoring higher.
