Oh yeah she's great. I actually recognize her from some other scenes, she's Harper the Fox. She has a thread here but unfortunately it doesn't look like it has much content that fits this theme - however, there's a nice collection of her stuff on incestflix, and they all have a nice little storyline and in most they aren't afraid to say the family relationship directly. In her thread here, there's this post where the brother-sister theme is heavily implied but they never actually say the words directly (sadly).
