I've been reading various different long stories and very little emotional turmoil takes place. I've read Variations on a Theme, Double Take, and a bit of Country Boy, City Girl along with almost all of Jay Cantrell's stories. In all but Jay's stories there seems to be very little drama, the stories focus on the sex and nothing really happens beyond that. There's no uncertainty, no doubt, as to who will fuck who, nor are there any breakups or hurt feelings (for longer than one chapter). I've been told that drama was coming in Country Boy, City Girl but I became bored by the story before I could reach it.
I am not asking for a story where everything ends horribly but rather something where the couple or poly relationship needs to overcome divisiveness or controversy or anger.
