Piper and Bandit are aces. That is, they are Top Guns. That is, they are fighter pilots who shoot down enemy planes in a heroic manner, thus earning themselves adrenaline rushes and numerous drinks as their reward.

In this case, Piper has saved his friend Bandit, whose ass was grass until the hero shot down the Chinese enemy in a marvelous manner.

Then they go on leave. Piper is a straight family man, loyal to his wife Ilene, whom he hasn't been with in over a year. Bandit is the Playboy of the Western and possibly Eastern World. They are on leave in Los Angeles, a city with a couple of million angels - er, women - to steal Bandit's attention. But then Bandit develops an eye for Ilene, and Piper's leave ends four days before Bandit's. What kind of an asshole would chase after the wife of his best friend - especially his best friend who has just recently saved him from certain death? Stay tuned to find out.

This is an excellent story. Good romance and hot sex in the context of a good action plot. What more could you ask for?
