Brother-Sister Incest/Web Original


 * That same website also has Becka the Beast, which features a weird variant: Gia and Becka fall in love, but circumstances involving Becka's abusive father force Gia's father to adopt Becka.
 * This has cropped up in Survival of the Fittest a couple of times (although in one case this was Twincest). Matthias Kovalenko of V2 was scarily obsessed with his sister Jodeen. (fortunately, she never made it onto the island). Nothing explicit ever occurs, but from Matthias' thoughts, most get the impression it isn't just brotherly concern.
 * Fortunately averted in Broken Saints:
 * In the Forest Tales (Chakona Space) setting, there are a number of examples of this (as well as some Parental Incest) between members of various genetically-engineered species such as chakats and foxtaurs. Hermaphrodite chakat sisters Forestwalker and Goldfur enjoy recreational sex, and foxtaur brother and sister Garrek and Malena are also mated (this is hand waved with the explanation that they have been genetically engineered to eliminate the sorts of diseases and conditions that inbreeding can produce in humans, and as created species do not share the exact same moral Squick factors as their creators).
 * Granted, Chakats and most other species still have taboos against inbreeding so Goldfur and Forestwalker are careful not to have sex when either one is in heat. Foxtaurs allow one generation of inbreeding because most of them can't leave their isolated Amish-style villages thanks to Territorial Attachment Syndrome, and a shortage of males.
 * Simon Bar Sinister and Penny Dreadful were a brother-sister team of supervillains in the Global Guardians PBEM Universe. In addition to being murderous psychopaths, they were utterly and completely in love with one another, to the point of getting physical while they were in the middle of a crime.
 * In Tea, Biscuits and Incest Mikayla eventually learns that her boyfriend Jayden is also her half-brother.
 * In supernatural web soap California Heaven, an episode features brother and sister, Dominic and KC, in a very seductive dance nearly kissing. Thought, it looks like KC was possessed. However, in a most recent episode, Dominic stares at KC as she is sleeping and she seems to have no problem with it.
 * Implied in Spooning With Spoony III, when Spoony fucks both The Nostalgia Critic and The Other Guy (along with plenty of other people) and tells the latter he makes noises just like his brother.
 * In The Gamers Alliance, Desdemona and Mordecai are siblings and very much in love although they have to hide their relationship from everyone else. Desdemona eventually gets pregnant with Mordecai's child and intends to give birth to the child, using it as a means to install herself on the Remonian throne by claiming that the child belongs to King Marcus.
