They pretty much grew up together though. I just looked up 'incest' on webster and it was defined as "sexual intercourse between persons so closely related that they are forbidden by law to marry; also : the statutory crime of such a relationship." Nothing there about blood relations. If I'm wrong, feel free to correct me.
