This. Especially if the aunt is close in age to the nephew. That adds an extra sexy dynamic to it.
>man meets a beautiful woman
>they become friends
>they develop strong feelings and attraction for each other
>they find out they're actually aunt and nephew, but didn't know this because the family was separated decades after a war or something like that
>the rest of the story is them trying to suppress their desires but failing and eventually getting married and having kids
