I was kinda struggling with how to answer this question, but I'll give it a shot.
If you're hoping for a big orgy at the end, you'll be disappointed; Book One is just the first step into a series of shortish games, so while stuff like that could happen in the future, the focus is going to be on the murder investigation and the resolution of that. It's a game with sex in it, but not focused on it.
If you're hoping to see Kylie (or Kyle) with a group of girlfriends that don't hate each other, than that will happen.
