You should just never announce that you're not going to write things. You inevitably end up horrifying yourself.
I have the oddest incest-squick when it comes to fic. The more happy and functional they are, the more squicked I am. So if it's non-consensual incest, I'm not really squicked, because that safely falls into my "Bad and wrong!" mental box. If it's twisted consensual incest, I generally avoid it, although I can very rarely be sucked in (if it was for a show I cared about, the fact that you wrote it would probably be enough to get me to read it, but the combination of consensual incest and "I have no interest in this show!" is enough to get me to not read). Happy funtime incest fic makes my skin crawl.
