Prompt: Character A and character B have been married or in a relationship for decades. Late in life, A decides that he or she wants to try an open relationship or a poly relationship. How does the couple deal with this?
Suggested Characters/Pairings: Any, but I don't want to read about a heterosexual male looking for a new girlfriend.
Theme/Tone: smutty, dramatic, maybe a little angsty
Additional Info: Every character involved in the romantic or sexual activity should be above the age of fifty -- in other words I'm not interested in reading about an older character wanting to fool around on his or her partner with a young character.
