A boy and his sister write lewd books together. Presumably they will also do lewd things together.
Despite the terrible subject matter, this was a pretty strong first episode. It did a good job setting things up, establishing both siblings’ characters, and kept my interest. I can sort of understand them falling in love despite the sibling thing, since they are step-sisters, from what I gather they never lived together while their parents were alive, and they didn’t meet until they were horny teenagers.
So, yeah, I’m surprised, but I actually liked this. Somewhat looking forward to the rest.
