The story of Lot always intrigued me. The Bible, actually sanctioning incest? But it really is there if you know where to look (Genesis 19:30-38). Even better, its the daughters who plot to bed their aging, widowed father who had no sons.
To My Daddy, who lies within me,
Happy is our love.
...and when you cum,
I'll be fecund, tonight,
As I'll miss my menses.
Give me again your heady seed,
And forgive me now my lurid intention,
As I forgave you when first we bedded.
And if you'll not feel irritation,
I'll deliver you a baby,
For ours is the loving,
And the climax, and the glory,
