Curiously, long time ago, let's say around 6 years ago, I found Niku Ringo style a bit "unfitting" for my standards, nowadays, and after travel and know more than before, cant avoid but laugh´about myself about the silly I was, because Niku Ringo is an awesome master, his fetishes are quite rude for some people but is indeed inciting and arousing. And of course with his evolution we can appreciate that more easily. So let's take this as proof that everything is a matter of perspective and emotional maturity.
Note: Maybe I'm an idiot, but I remember seeing this with a full color cover somewhere else, or is just my senile memory?
