Yes, I do look at incest depictions if I really like it (BelarusUkraine for foreign affairs and YuiUi for obvious reasons) but I find it hard to believe someone would actually go so far as to support it in real life.

"Mmm well unlike most peope I'm not against incest. I feel if you truely love the person in such a way it shouldn't matter who you are as long as it's mutual."
