* While the book doesn't get that far, in ''Literature/MajykByDesign'' by Creator/EstherFriesner, a cat (talking, magical) named Scandal gets split up into a number of copies by villains (who can control the copies). By the end of the book, he reabsorbs them. ''Except'' for the one representing his female side, who being just a kitten was useless to them and out of the fight. He's accelerating her maturation, for this trope's purpose, with her full encouragement. (They ''are'' the only two cats in this world...)
* "Nine Lives", an early Creator/UrsulaKLeGuin story, has a set of ten clones, five male and five female, who join some place where there were already two normal people working. When the clones have sex with each other, one of the non-clones says, "Oh, let them have their damned incest!" and the other says, "Incest or masturbation?" (The clone-sex wasn't a major plot point, just a part of showing how the clone-group couldn't relate properly to outsiders.)
* A similar case of clone incest appears in Creator/JohnVarley's ''[[Literature/GaeaTrilogy Titan]]'', where the lab-cloned Polo sisters privately engage in behavior that's still illegal in Alabama.
* Varley's stories have often had this, including ''The Phantom of Kansas''.
* Used romantically with several pairings amongst the {{Starfish Character}}s in ''Literature/ScorpionShards''. They are soul mates, so to speak, but it gets a little weird when one of them realizes he can't fall in love with someone who isn't part of the group.

* In Creator/FrederikPohl's ''The Coming of the Quantum Cats'', similar characters from a mulititude of timelines mix & match during a cross-time war; when a slightly more advanced timeline decides to quarantine the others to avoid eddies in the space time continuum, a lot of editions get dumped on an uninhabited Earth, where multiple copies of a particularly unsavory mook decide to set up house together.
* In ''Literature/WithATangledSkein'', Niobe kisses ''two'' alternate timeline versions of herself. Clearly justified, as Niobe is essentially described repeatedly as the most beautiful woman of her generation.
* The short story "Blood Sisters" by Creator/JoeHaldeman involved the Mafia cloning a young heiress in order to substitute the clone and get the inheritance. The clone didn't want any part of the plan--she thought of the original as her mother and didn't want her murdered--and went to a private detective to ask for help hiding from the Mob. When she finally ''met'' the heiress, however, the mutual attraction was strong enough to overcome any qualms about [[ParentalIncest being intimate with her mother]]. The detective comments, "I did wonder what you would call what they were doing. Was it a weird kind of incest? Transcendental masturbation?" At the end of the story, it's mentioned that original and clone openly being lovers "started a fad among the wealthy, being the first new sexual diversion since the invention of the vibrator."
* A strange case in Creator/SergeyLukyanenko's ''Autumn Visits'', where Anna has a [[NoodleIncident "shower moment"]] with her not-quite-human duplicate Mary. It's not specified exactly what they do in the shower, but their mutual attraction is clear, although Anna's attraction is partly due to religious fervor (she believes Mary to be {{God}}). The not-quite-human duplicate of AuthorAvatar describes the event as "a real bad case of narcissism".
* Creator/IsaacAsimov wrote a parody of "Home on the Range" called "Home with my Clone" ("...with the Y chromosome turned to X.")
* In ''Literature/{{Redshirts}}'', the main characters get [[spoiler:the actor playing one of the stars of the television show they're characters on]] to help them when [[spoiler:the character he plays]] seduces him. [[spoiler:Or not, they actually just talked.]]
* In "A Clone at Last", a short story by Bill Pronzini and Barry N. Malzberg, a man who has little luck with women commissions a female clone of himself. He waits until the clone is eighteen years old before he tries to seduce her to avoid being arrested for statutory rape.
* In the book ''Literature/{{Goldfinger}}'', when he has captured Bond and expects him to talk (also to die), Bond steels himself, telling him "you can go [[NarrativeProfanityFilter ____]] yourself." Goldfinger good-naturedly replies "Even I am not capable of that, Mister Bond!"
