Lol, I can't. Indeed, as soon as Q-knife was mentioned it made me think of Car Fight and Susan - A Girl Apart.

Not to say that I didn't enjoy it at all, but unfortunately I can't say I enjoyed this story as much as Car Fight and Susan. But that's more because it took things in a direction that felt more weird, and also the whole mother/daughter incest isn't my thing. Can't say anything bad about writing, just didn't happen to fit my fetish.
