Threesome — Lawrence Block

There's more than one side to every story -- especially in a threesome

Harry, Priss, and Rhoda have a brilliant idea. They're going to write the best “bad” novel and they'll each contribute one third of the story. But what to write about? How about their unusual arrangement? And so this tale of steamy liaisons begins, as Harry and his wife, Priss, welcome randy divorcée Rhoda into their lives -- and their bedroom. The three adventurers embark on an erotic journey that will prove that three is a very pleasure-filled crowd.
