I was looking more for the mother and father being the parents of themselves.
This is as close as I can find.
The daughter goes back in time to ensure her parents (step brother and sister) conceive her, [spoiler]but she ends up having sex with her own dad, spoiling any chance of her parents having sex, and getting erased from existence until her dad forces himself onto his sister and ensures his daughter gets conceived.[/spoiler]
