Ashley and Dan go on a cruise with their best friends, Rachel and Matt. The cruise turns out to be for swingers and they wind up changing partners with each other. Swinging with their best friends was easy, now they're about to do it with total strangers. Something that before getting on board the ship they never considered. Now they are on board for everything the lifestyle offers. Dan is immediately seduced by the idea of having sex with a woman other than his wife, especially since she is so different from Ashley. He has the best sex of his life and while at first, Ashley was not keen to the idea of sex with a stranger, the man turns out to be nothing like what she expected him to be. She definitely enjoyed the new experience.
