``We're siblings, so... we'll just rub each other.'' It's been 10 years since I asked my good-natured older sister, who is too kind even to me, a NEET, to help me with sex on the condition that I'd even get to her bare legs. One day, when I inserted 2cm of the tip into her wet pussy, she didn't say anything, so I creampied her and had incest. Amamiya Kanan
