Here's my choice: I picked Sara from the very first introduction, and had to wait until this update fro any content with her. I couldn't tell you why, but she just clicked with me. Then comes Meg, probably due to the fact that she has had so much content compared to the other girls at school. Following her is Daughter, but for different reasons. The others are "conquests" (sort of), while D is "real" love. Kait is next. She is the secret slut...wants you to jump her and fuck her like she's never been done, but wants others to think she finds you disgusting. Then Wife. Yeah, I fucked her. Yeah, I mind control fucked her. But that was cause my wienie needed some vag to make it feel better. I tossed her aide as soon as I got off. Last is Zoe. She is last because, well, face it - she is the one we know the least.
Now, having said that, Meg and D are REALLY close, almost tied, and Sara is barely ahead of them. Wife is off to the side, and only kept around as a guaranteed way to get my dick wet. Really need to see how things develop, so to speak, so that we can see if the order changes.
