Most taboo stories follow the build up to “crossing the line.” That’s where the dramatic tension is. I thought–what if the real tension occurred after they had?

Then I heard a philosophical question about incest: if adult siblings on vacation had a drunken night together and no one knew, would it still be wrong? My answer has always been about consent rather than the specifics of the relationship. So I thought–what about marrying the two idea?

Then it was just a matter of waiting until I had the characters formed in my head.
