As for reality, it depends. These tropes tend to gross out anyone who has been raised alongside their stepsiblings. If they met as teens or later, though, it can seem unfair that their parents got got together before they did.

Added DiffLines:

* In Sharon Maas's ''Literature/OfMarriageableAge'', Saroj finds out Nat is her half-brother, only after she's carrying his child. [[spoiler:Of course it turns out she's adopted, in the end.]].
* BrotherSisterIncest is invoked in Richard Ellis Preston Jr.'s ''Literature/ChroniclesOfThePneumaticZeppelin''; although he was seven when adopted, and Max an equivalent age (for a HalfHumanHybrid), and Sabrina was thirteen, Romulus feels guilty about being attracted to either, because they are adoptive siblings.

* LightNovel/TheIrregularAtMagicHighSchool: It's play quite difficultwith this when it turns out that Miyuki is an [[spoiler: [[DesignerBaby improved magician]], that is, she was artificially created, and then genetically modified to have powerful magic powers so that she could stop her brother from destroying the world, if needed. In this way, although she and Tatsuya are certainly blood-related siblings and have the same parents, their genes are quite different so that their potential BrotherSisterIncest connection is safe for their offspring. Later they are engaged, although their feelings are not mutual]].

Added DiffLines:

* It's subtly hinted and discussed in Manga/TanteiGakuenQ about the relationship nature of two stepsiblings Tomoe and Ukon Kiriyu in Setsugekka Murder Case. It's apparently one-sided since the side shown to readers is Tomoe's who tries her hardest to prove Ukon's innocence before TheReveal (he was framed as murderer of his other two stepsisters) while Ukon himself [[spoiler:[[ObfuscatingStupidity pretends to be an airhead]] as he is suspicious that all his stepsisters and stepmother were involved in his father's past accident]]. Kazuma assumes the trope is in play and the stepsiblings' father Samon asks what Tomoe thinks of Ukon. Too bad [[spoiler:she is the true murderer. While later she admits her feelings for Ukon are real, when [[MasterOfDisguise Nanami]] disguising himself as Ukon confronts her about the murder she [[HeKnowsTooMuch immediately stabs him]]]].

* On ''WesternAnimation/{{Gargoyles}},'' the title species lives in large clans that are considered to be a single family--nobody keeps track of who their biological parents are, and thus all gargoyles of the same age group refer to each other as their "rookery brothers/sisters" and older members as their "rookery parents." Their mates are usually rookery siblings. WordOfGod says that real incest never occurs, though, because a) each female can only lay one egg per mating cycle, so rookery siblings never include ''actual'' siblings except in the rare case of twins and b) pheromones prevent [[KissingCousins Kissing Cousin]] relationships.
