"Naked Option" is a story of greed and lust, set in the "anything goes" New York City of the mid-1960's. Preston and Margo are an attractive and striving young professional couple. They enjoy an active sex life without any commitment to the future. Preston is a rising and determined investment banker, dedicated to serving both his clients and himself by succeeding in the stock market. Margo works as an architect. Almost by chance, the couple becomes entangled in the life and fortunes of Sidney, a stranger from an entirely different background who enlists Preston to make money for him on the market. Unknown to the couple, Sidney runs a sex club across town. At first, Sidney's amorality and apparent generosity, his eagerness to learn the ways of the elite, and his obvious physical attraction, is seductive to the young couple. Preston and Marlow join in tutoring him in the mores of the elite social group they represent, and the three explore their sexual interests together.
