* Laura Ingalls Wilder mentions in her ''Little House'' books that this is the way she and her cousins are related.

* In ''HowIBecameYours'', Zuko gets together with Katara... and Azula with Sokka. Though ''lots'' of CharacterDerailment and Katara's love interest Aang hooking up with Toph.

* There exists somewhere an "ending" written for the ''ArabianNights'' that was made several hundred years later, in which Shahryar had magically fallen deeply in love with Scheherazade, decided to keep her, and then his brother magically fell in love with her sister so they could be one big happy family. Never mind that it was poorly written, completely [[CharacterDerailment derailed the king's character]], imposed European-Christian values on the story, and was just a little [[{{Squick}} creepy]] near the end. Basically, it was a glorified FanFic written somewhere in the middle ages.

* ''Howe & Howe Tech'' is about a company run by twin brothers Mike and Geoff, with their wives, Tammy and Tracy, handling office work. Tammy and Tracy are sisters.

The children of one couple are "double cousins" of the children of the other. Since they are as genetically similar as half-siblings, KissingCousins is even more discouraged in such cases.

Bob and Janet are siblings. So are Spencer and Alice. Alice marries Bob, while Janet falls in love with Spencer. In other words, a pair of siblings marry another pair of siblings. Someone marries the sibling of their own sibling's spouse. A quick way to achieve WeddingsForEveryone. Or if the weddings don't take place at roughly the same time, the first wedding provided the ideal opportunity for the second couple to get to know each other.

Not to be confused with BrotherSisterIncest or SettleForSibling (although overlap with the latter is certainly not impossible).

* Mentioned in an aside in To Kill A Mockingbird, although not actually featured. Atticus mentions the concept of double cousins to Scout, saying "two brothers married two sisters." She and Dill work on figuring it out, and reason that if Dill had a sister whom he married, and Jem and Scout got married, their kids would be double cousins. Only off by a little bit there...

** ''SenseAndSensibility'': John Dashwood and his half-sister Elinor Dashwood marry sister and brother Fanny and Edward Ferrars. John and Fanny are already married before the book begins, but Elinor and Edward don't get married until the end (an ArrangedMarriage and ChildhoodMarriagePromise were in the way).

* ''{{Roseanne}}'': Darlene and Becky Conner married David and Mark Healy, respectively.

* In Amy Tan's ''The Bonesetter's Daughter'', sisters LuLing and GaoLing marry brothers Edwin and Edmund Young.

** ''MansfieldPark'': Mrs. Grant plans for her brother and sister Henry and Mary Crawford to marry siblings Julia and Tom Bertram. They both blow it, starting by flirting with the other two Bertrams Maria and Edmund. Note to [[ShipperOnDeck Shippers On Deck]]: Make sure the sides are balanced before attempting this trope. Ironically, at least 2 {{Fan Sequel}}s -- ''Susan Price'' and ''Mansfield Revisited'' -- invoke this trope by marrying Fanny's sister Susan Price to Edmund's brother Tom bertram.
