1) I really hope we actually get to fuck the lolis in the ass this time. They didn't have that in the Slave Route.
2) I also hope we figure out what changes between taking Katara/Korra's panties, and giving/keeping them from Kya. I don't mind there being forks in the road, I just wish we knew what we were potentially getting into.
3) Also there's a possibility for even more debauchery if we get Katara to loosen her code about incest which I'm really hoping for.
It's just better when you know someone is crossing their own boundaries. So the potential of Katara and Kya, would be awesome.
I wonder if there is a way to get Katara, Kya, Pema, Jinora, Ikki all at once without it feeling forced and contrived? Like if there was a side plot where you get one of the girls to give in and help you convert every girl in their family for one massive orgy.
Of course this is only something that should be done if the devs have the time to make it good. They have a lot on their plate already so I'm just throwing out ideas of ways to take this story to the next level.
