Some of our clients call a lot. When you talk to the same guy again and again, some creativity is necessary to make it feel fresh and interesting each time...

Other callers don't really want to talk. They specifically ask you to tell them some sort of a story (popular ones are your first time, first experience with another girl, the naughtiest thing you've done)... Sometimes, a caller will just want to listen to you tell him a hot story... something dirty that you did that you can "confess" to him... Look to movies, books, online erotica, magazines for dirty stories to tell when your caller is asking for that. Remembering the scene and adding interesting details will give you a backdrop - your storytelling skills will make him believe it was you...
