Just heard the phrase \"No Chromo\" in relation to this trope (from YT anime reviewer Gigguk) and thought it might be an amusing name for it.

I would like to add an example of this trope. It comes from the anime Schwarzesmarken, where the protagonist Theodor Eberbach has sexual relations with his adopted step-sister, Lise Hohenstein. I don\'t remember if the audience revelation that they\'re step siblings come before or after they\'ve engaged in sexual intercourse.

I thought this was just about not being blood siblings, not a love/incest trope. D:

The kind of thing you get to learn every day.....

"In The Lion King 2, isn't it so convenient that Kovu isn't really Scar's son, making it perfectly okay for him to get it on with his cousin?"

Anviliciously hammered in within the first twenty seconds of Kovu's appearance. And Kovu would be Simba's cousin, Kira's second cousin or once-removed cousin or something, so it's not even that squicky from that perspective.

Although if Nala's Scar's kid, that means he's dating his niece... Mufasa's, half-brother/half-sister romance. Or Nala's mom just showed up in the territory already pregnant one day. :p

Big example missing under Comics. The original back-story given for the Post-Crisis Lex Luthor involved him falling for his step Sister Lena.

I'm normally a huge fan of trope images, but this is the perfect example of a bad one. Doesn't illustrate the trope at all, other than his quote.

Does it bug anyone but me that saying not being blood related means its perfectly acceptable for two siblings to screw? (In the sense that it shouldn't matter if they're related, its their lives their choice)

Or that Not Blood Siblings seems to be overly used as some kind of cop out when writers want to get all that "Forbidden Romance" stuff but are too pussy for the squick associated with Incest?

The second part does bug me. As for the first I think "it's their lives, it's their choice" should apply even if they are blood related however further discussion of that belongs on the forums I think.

I don\'t see why it should bother anyone. By definition if two people are not blood related, than they are not siblings. \"Step-siblings\" is nothing more than a social construct.

Type the word in the image. This goes away if you get known.
If you can't read this one, hit reload for the page.
The next one might be easier to see.

How well does it match the trope?
