Speaking strictly in legal age, consenting relationships, I wouldn't see a problem for parent-offspring relations either. Fact is though that those kind of relations happen a LOT less (in fact I can't recall ever hearing about it, now that I think about it) then a sibling relation.
As for my own future children, if they reach the age of 16ish and on some unfortunate day I find out they are messing around with each other, consenting and all, then I won't make a big fuss about it. I'd sit down with them and have a chat, ask some questions (for the love of god, tell me you didn't get your sister pregnant!) and would respect their decisions in the matter unless they start talking about having kids.
A household can get a little tense in a situation like that though. In the back of your head you'll always be asking yourself as a parent if they are upstairs doing their homework or learning for a biology exam.
