Rent Animal Instincts (1992)

A cop and his sexually frustrated wife are struggling to keep their failing marriage intact, when by chance he finds that at heart he is a voyeuristic Peeping Tom. Joanne is caught by David in a compromising position with the cable television man. Only now she realises, that the way to get her husband's interest is to let him watch her illicit liaisons. In order to satisfy him, Joanne embarks on numerous affairs, which her husband watches on closed-circuit television. David plunges deeper and deeper into prostitution and deception and soon the couple are involved in a scheme that could blow everything sky high. It's a hard lesson to learn but if you play with fire, you'll always get burnt.
