Oh there is a bit in the bible (I think in Genesis) where lot fucks his daughters because they want to have children and God has just destroyed the world again so he is the only man. They know that he wouldn't consent so they get him drunk and then do him.
In fact I google searched it and here it is:
Revised standard version
Genesis 19:30-35
Now Lot went up out of Zo'ar, and dwelt in the hills with his two daughters, for he was afraid to dwell in Zo'ar; so he dwelt in a cave with his two daughters.
And the first-born said to the younger, "Our father is old, and there is not a man on earth to come in to us after the manner of all the earth.
Come, let us make our father drink wine, and we will lie with him, that we may preserve offspring through our father."
So they made their father drink wine that night; and the first-born went in, and lay with her father; he did not know when she lay down or when she arose.
And on the next day, the first-born said to the younger, "Behold, I lay last night with my father; let us make him drink wine tonight also; then you go in and lie with him, that we may preserve offspring through our father."
So they made their father drink wine that night also; and the younger arose, and lay with him; and he did not know when she lay down or when she arose.
King James Version
Genesis 19: 30-36
And Lot went up out of Zoar, and dwelt in the mountain, and his two daughters with him; for he feared to dwell in Zoar: and he dwelt in a cave, he and his two daughters.
And the firstborn said unto the younger, Our father is old, and there is not a man in the earth to come in unto us after the manner of all the earth:
Come, let us make our father drink wine, and we will lie with him, that we may preserve seed of our father.
And they made their father drink wine that night: and the firstborn went in, and lay with her father; and he perceived not when she lay down, nor when she arose.
And it came to pass on the morrow, that the firstborn said unto the younger, Behold, I lay yesternight with my father: let us make him drink wine this night also; and go thou in, and lie with him, that we may preserve seed of our father.
And they made their father drink wine that night also: and the younger arose, and lay with him; and he perceived not when she lay down, nor when she arose.
Thus were both the daughters of Lot with child by their father.
