" Many states also apply incest laws to non-blood relations including stepparents, step-siblings, and in-laws." - Wikipedia.
Now, I know its not exactly a credible source but the place the information is sourced from is credible.
"'Incest' is the sexual relations between closely related people, irregardless of age," is the definition according to the same source.
If you've ever thought of having incestuous relations, look up the law in your state first. (:
Because in the end, it doesn't even matter.
