Hindsight.

"Hindsight" explores the rear view in every way imaginable. Two egotistical and decadent sex masters, Herschel Savage and R. Bolla argue endlessly over who is the better lover. Circumstance, in the form of juicy Heather Wayne and scrumptious Stacey Donovan intervenes and devises a method whereby they might settle their conflict once and for all. The girls use hapless Craig Roberts as a sexual guinea pig. "What you can do, you can teach," decide the sexperts. Under their tutelage and with the help of today's most beautiful centerfolds, Roberts undergoes a remarkable transformation from dud to stud. But now the test! Can he go the distance that will prove him to be a true sexual black belt? Everything rides on whether or not he'll be able to perform the most infamous of all erotic tests: The Pakistani Double Drill Press!
