I replied with I would.
For me, I have no problems with incest. If two people in love want to have a physical relationship even though they are related, then I am no one to discriminate against it. It is against my principles and I would see myself as a hypocrite if I see incest relations in a different light than any other relations. Also, i would like to clear that my thinking comes from the fact that I have seen my cousin getting married to his own cousin (so that makes my cousin sister marrying my cousin brother who are both related to each other the same way I am related to them, via my mother's side of the family).
Saying that, I have never had any problem reading stories that contain incest. The only incest that troubles me, as Graeme put it, is rape or non-consensual and cross-generational. But that is true with all types of sex for me. I cannot bear to read/see cross-generational or non-consensual sex. Even BDSM or kink is a big turn off for me. In short, I like vanilla-sex. A bit of role playing is fine... lol
Coming back to the topic, I have read many stories that involve incest, both on literotica and nifty. Again, stories that revolve totally around sex with no plot whatsoever are a big not for me as a reader. My Step Brother Jacob, is one example. While having a good plot, it contained to much of explicit sex and that is a big turn off for me as a reader, be it any type of story.
While reading, I look for a good plot and good writing skills, the pairing doesn't matter. If the story is well put, I would certainly read it.
Just my .5 cents
