Sometimes divorce lawyers make separating couples realize that, for financial reasons, they may have to continue living together. This isn’t something that Lexi Luna and Tommy Pistol really want to hear, but they bite the bullet and continue to co-exist despite the fact that each has moved on to a new partner.

Pistol is now with busty Melissa Stratton, whom he met at a strip club, and Luna has set up shop in the arms of well-tatted Derrick Pierce. Along the way, their mutual friends Ricky Spanish and Ryan Keely prove to be an unlikely pair with similar sexual desires.

The love/hate attraction between Luna and Pistol proves to be too much, and they continue to screw one another unbeknown to their new partners—hence the title. This continues until Stratton and Pierce discover what's going on and wind up together.
