so clearly this author is into incest. thanks for letting us know your fetish that we didn't really need to know about. honestly people should stop saying alabama and instead say japan. although i don't know how often it happens in japan, i can at least say it seems to be something that is hiddenly wanted by them from how many manga/novels/anime/games exist that involve the concept of incest and by the popularity of such things. if you want me to name any such "popular" series that exist oreimo is the perfect example of this. we know that in alabama it definitely happens but japan puts it into their entertainment far more often. not judging here since i don't care what you want to put/rub your d*ck/p*ssy in/on but at the very least keep it to yourself if its irrelevant to the story your trying to tell.
