History BrotherSisterIncest / WebComics

* [[http://the-qlc.com/loserz/go/390 This]] ''Webcomic/{{Loserz}}'' strip mentions [[Franchise/ResidentEvil Chris and Claire Redfield]] having such a relationship.

* [[http://www.studs-up.com/2009/12/analagous-madness/ This]] ''Studs Up'' comic has two people discussing this trope as an analogy to being a [[UsefulNotes/EnglishPremierLeague Spurs]] fan. They almost got to the logical conclusion before {{Squick}} sets in.

* Touched on in ''Webcomic/GirlGenius'' -- WordOfGod says that [[spoiler: Gil and Zeetha are fraternal twins separated at a young age -- which makes [[http://www.girlgeniusonline.com/comic.php?date=20080418#.VvGHluKLTIV the scene]] where Gil walks around the room naked with Zeetha watching appreciatively, until she points out that he's not wearing any pants,]] actually kind of squicky.

* In the MassiveMultiplayerCrossover [[FanWebComics fan web comic]] ''Webcomic/GrimTalesFromDownBelow'' by Bleedman, Minimandy/Minnie seems to love her brother, Grim Junior, in a manner beyond what would be acceptable sibling behavior.
** Her heretofore ambiguous feelings, once made explicit, are also cranked up to AxeCrazy levels as indicated by [[http://grim.snafu-comics.com/?comic_id=107 this late strip]]. Although, she is [[NotHimself Not Herself]] there. Afterwards [[http://grim.snafu-comics.com/?comic_id=136 she doesn't seem to have given up hope]] and his response seems ambiguous. In still later strips they seem to have settled down to a PseudoRomanticFriendship until Mimi shows up, arouses Minnie's jealousy and just plain arouses Junior.

* ''Webcomic/PowerpuffGirlsDoujinshi'' takes the mild vibe between [[WesternAnimation/DextersLaboratory Dexter and Dee Dee]] mentioned below and runs with it.

* In ''Webcomic/{{Shortpacked}}'' it's revealed that Amber and Faz are half siblings...which is a problem for Amber, as Faz had been [[SurpriseIncest hitting on her]] since the day they met. She's also reluctant to tell him the truth because she fears that that would just ''encourage'' him by invoking UsefulNotes/GeneticSexualAttraction. [[spoiler:She eventually tells him when their father dies. He does end up losing interest in her, though it seems to be less about them being siblings and more about him feeling betrayed that she didn't tell him sooner. (Him finding a girlfriend certainly helped, though.)]]

* ''WesternAnimation/TheLoudHouse'':
** The Spanish web comic ''[[Webcomic/TheLoudHouseCuevaDelCaos Cueva del Caos]]'' is built around this trope, with Lincoln and Lynn getting into a relationship after coming across a secret room in their basement and [[spoiler: Lincoln having affairs with Luna and Leni.]]
** This is the premise of the Webcomic/SinKidsAU, in which Lincoln has impregnated all of his sisters.

In still later strips they seem to have settled down to a heterosexual version of a TwoGirlRomanticFriendship until Mimi shows up, arouses Minnie's jealousy and just plain arouses Junior.

* ''[[http://www.absolutehotsister.com/ Absolute Hot Sister]]'' is built on this trope. Ellen has gone so far as to suggest to her brother Kevin that they sleep in the same bed and take showers together.

* In ''Webcomic/FeyWinds, two members of [[BigBad Sigurd's]] Minionz, Hansel and Gretel, apply.

* Averted in ''Webcomic/DanAndMabsFurryAdventures'': Dan seems to find thinking about his half-sister in a sexual way as [[{{Squick}} squicktastic]] [[http://www.missmab.com/Comics/Vol_692.php as the average troper]].

* In the MassiveMultiplayerCrossover [[FanWebComics fan web comic]] ''Webcomic/GrimTalesFromDownBelow'' by Bleedman, Minimandy/Minnie seems to love her brother, Grim Junior, in a manner beyond what would be acceptable sibling behavior.

* In ''Webcomic/{{Polkout}}'' [[http://www.polkout.com/page156.htm it's the reason Polkster wants an older sister.]] TOTALLY {{NSFW}}.
* [[http://the-qlc.com/loserz/go/390 This]] ''Webcomic/{{Loserz}}'' strip mentions [[Franchise/ResidentEvil Chris and Claire Redfield]] having such a relationship.
* ''Webcomic/PowerpuffGirlsDoujinshi'' takes the mild vibe between [[WesternAnimation/DextersLaboratory Dexter and Dee Dee]] mentioned below and runs with it.

* ''Webcomic/NSFWComix'' has Cuthwald and his sister. Averted at first, but [[spoiler:played straight after [[NotQuiteDead he was rescued from being cremated at his funeral]].]]

* ''[[http://www.absolutehotsister.com/ Absolute Hot Sister]]'' is built on this trope. Ellen has gone so far as to suggest to her brother Kevin that they sleep in the same bed and take showers together.
* [[http://www.studs-up.com/2009/12/analagous-madness/ This]] ''Studs Up'' comic has two people discussing this trope as an analogy to being a [[UsefulNotes/EnglishPremierLeague Spurs]] fan. They almost got to the logical conclusion before {{Squick}} sets in.
* ''Webcomic/TowerOfGod'' has [[MagnificentBastard Khun]], a BlueBlood who is rumored to be in love with his half-sister Maria.
* This is a key part for one of Butterfly's slaves in ''Webcomic/{{Collar 6}}''. She and her sister were both married to the same man, since polygamy is okie-dokie in this world, and he thought they should engage in this. She didn't agree while her sister did. That got her shipped off to attempt unpleasant "changing" in her thinking.
* Apple and Orange from ''Webcomic/FruitIncest'' make no efforts to hide their relationship from the audience, to the point that their cousins are more visibly squicked by their SickeninglySweethearts status than the actual incest part.
* ''WebComic/RiceBoy'' has a rather... uncomfortable sequence where Golgo, increasingly unstable and depressed, [[http://www.rice-boy.com/see/index.php?c=152 has sex with his apparent sister]] with their facial expressions implying that this isn't the first time. And unlike some examples, he ''really'' doesn't seem to enjoy it. Subverted as we later learn [[spoiler: Golgo is a Searcher, meaning that she isn't really his sister at least not in the conventional sense (if she was she'd be over 3,000 years old by the time of the story). Somehow this reveal doesn't make the above scene any less unsettling.]]
* Touched on in ''Webcomic/GirlGenius'' - WordOfGod says that [[spoiler: Gil and Zeetha are fraternal twins separated at a young age - which makes [[http://www.girlgeniusonline.com/comic.php?date=20080418#.VvGHluKLTIV the scene]] where Gil walks around the room naked with Zeetha watching appreciatively, until she points out that he's not wearing any pants,]] actually kind of squicky.
* Megaman and Roll is ''maybe'' this in ''Webcomic/MegamanSpriteComic''. [[http://megamanspritecomic.tumblr.com/post/15144466769/this-is-the-first-comic-and-megamans-brother-zero Megaman seems unsure himself]], but certainly doesn't seem to mind it.

* In ''Webcomic/{{Shortpacked}}'' it's revealed that Amber and Faz are half siblings...which is a problem for Amber, as Faz had been [[SurpriseIncest hitting on her]] since the day they met. She's also reluctant to tell him the truth because she fears that that would just ''encourage'' him by invoking the genetic sexual attraction concept.

* ''Webcomic/TowerOfGod'' has [[MagnificentBastard Koon]], a BlueBlood who is rumored to be in love with his half-sister Maria.

* In ''Webcomic/{{Shortpacked}}'' it's revealed that Amber and Faz are half siblings...which is a problem for Amber, as Faz had been [[SurpriseIncest hitting on her]] since the day they met.

(Him finding a girlfriend certainly helped, though.)

* ''Webcomic/BetterDays'' and ''Webcomic/BadlyDrawnKitties'', which had a shared cast of characters, including twins Fisk and Lucy Black. The two comics used the sibling's special relationship in completely different ways. ''Better Days'' used the relationship [[http://www.jaynaylor.com/betterdays/archives/2004/10/chapter-10-brot-19.html dramatically]], while ''BDK'' used it as a CrossesTheLineTwice RunningGag.
** Although as ''Better Days'' progressed both characters seem to deny it happened, it slowly became a forgotten dropped storyline, and both moved on to their respective RelationshipSue

** At one point, Doctor Lovetalk's sex-therapy radio show takes back-to-back calls from a brother-sister pair trying to enact their violent rape fantasies on each other. [[NoJustNo She hangs up on both calls]].
