White Bunbusters(1985)

Poor John Doe. All he wants to do is to try a little anal sex with his wife, Jane, but she absolutely refuses! Little does he know that a single call to 'A-Busters' would solve all his problems. For a nominal fee, the A Busters, Buck and Tex, will cure all of your lover's anal fears with their patented 'Lube 'em and Ream 'em' method. So while John wastes his life away worrying about his wife's butt, Buck and Tex work their anal magic on a number of very beautiful, very horny and very satisfied customers. After tasting the joys of back door boffing with his best friend's wife, John finally picks up the phone and makes the call to 'A-Busters.' And boy, is he glad he did!
