Well, if this thread is anything to go by, the playerbase doesn't really care much about the younger girls, it's all about the Milfs. The dev is just giving the people what they want, which is fine by me.
I wouldn't expect that chick to return anytime soon, since the young girs are already an afterthought, and there's still Susan's daughter and that girl who works at the bar waiting in line to get fucked. Eva + Nora threesome on the other hand, should be happening any update now given this one's developments.
