Now, I'm not going to rail on you the way Esmeralda did, so please refrain from throwing tomatoes and dildos at me.
But I just have to wonder if people who write fluffy!incest fic even have siblings. Because if the majority of incest writers are only children, maybe they don't understand the psychological damages and repercussions of the act, or why it'd be considered gross to think of a sibling in a romantic/sexual way. [insert another page of tl;dr]
Now, I'm not saying people should never write incest again, if they think blood relatives going at it is hot, fine, whatever makes them feel good in the tingly spots. I simply find it disgusting and cannot fathom why anyone with siblings would think it's so attractive, that's all.
