So little known fact, I'm actually a huge pervert. That being said, this manga hits so many fetishes for me... I just think its awesome. I have kind of a thing for tall women, cavewomen, and a whole lot of other things I'd rather not post. But I think it's great. This isn't a deep story or anything but there actually IS a plot, believe it or not. Heck the story even has a touching ending, which I kinda wasn't expecting.
If you're looking for some good smut then you've come to the right place as far as I'm concerned.
