The story of Lot always intrigued me. The Bible, actually sanctioning incest? But it really is there if you know where to look (like Genesis 19:30-38). Even better, its the daughters who plot to bed their aging, widowed father who had no sons...
My daddy's my lover; I want none else.
He lieth within me in green pastures:
He lieth within me by still waters.
He rocketh my world:
He leadeth me in the paths of pure incest, 'cause I want him to.
Yea, though we kiss in a world that could bring our deaths,
I shall fear no evil, when he is within me;
His rod, a thick staff, it comforts me.
He preparest the bedroom just for me, like unto my fantasies;
He annointest my vault with semen; My cunt runneth over.
Surely climax and babies will follow me all the days of my life,
And I will dwell in my lover dad's house forever.
