Tired of Las Vegas every vacation, three couples, college friends, decide to make it a nudist resort this year. "How can the guys keep from getting erections all the time?" one wife asks and one of the husbands suggests lots of sex. They do all work out a fun plan to handle their hardness when it arises but it seems to get out of hand, so to speak. Why not come along and enjoy it along with them? It's nearly as fun as being there. If you like lots of sex, that is.
