It's weird to consider because of it all. I'm not sure if it entirely qualifies, but in my head:
Kiyoko is "Champsexual", right? Berwyn after learning about the experiences Kinu goes through, companions go at each others throat. You let them calm down, but then you can give Berwyn the option to fuck her down several pegs, at the gain of some corruption. If the bitch is gonna be under the eyes of a trickster god, then all trickery is fair game for some payback.
It'd probably end up as NTR by the end of it, if you consider Berwyn's stamina.
