incest story idea

[Guest]

Would like to read a story about two successful middle-aged brothers who have been accustomed to sharing each other's wives, unbeknown to their teenage daughters. When their wives both leave (with each other) the husbands are bereft, emotionally and sexually. Their daughters console them, first with each uncle (at Dad's suggestion) and then with their own father. Story ends with the kind of orgy that they used to have with their wives.
Will check back to see if anyone has written this. No Qs please. I would like to see how many variations on this theme people invent and I do not want to structure it anymore than the bare outline above.
