I definitely don't consider step-sibling romances to be incestuous at all. And I don't think that incest could reach the height of slash, simply because of the fact that I don't find slash to be disgusting in the least, while incest is just gross and I believe that a lot of people feel that way. It will be a lot harder to spread the world of incest, than it would be to spread slash in fandom/fannon. Generally, I don't think that people look at the moments between a mother and son, and respond with a "Wow, that was hot."
