Brothers having their way with their sisters is cool, as well as the other way around.
Another thing that would be cool and fun to read, would be if a whole family(both sides),got together for a family reunion and ended up screwing their brains out.
How about if a brother and sister (both in their mid to late 30's) arrive at one of their homes to find out that the house has been burglarized and the burglar is still there. He makes them both strip (they came from prudish family and have never even seen each other naked) and suck and fuck each other while he watches.
George,
I finished a story with your idea tonight look for it in the future if they decide to put it on and let me know what you think! It is called "Brain, Brawn and the Beauty"
