I'm new, and the idea of writing fantasies for other people is very exciting to me. Three things, does it have to be from your first-person POV? I'd much rather write it in the third person, with the main character being the wife. Second, it's a great erotic concept, the youth pastor's wife, and I think there are a million places to go with it. Your specific fantasy seems to short change it. Meaning, what you describe is the plot to a thousand different porns, each indistinguishable from one another. It could be much more interesting, say, if it takes places during a youth group retreat... or at the church itself. Third, I'd rather the youth pastor's wife's name be my own.
