I'm adding the Minator-lady to the list of characters with some depth. It seems like she and maybe even the Dullahan are forced to work for the big bad at the end simply because he's in charge. That add level of story, or even tragedy, adds to the sex scenes for me. I'm not just fucking some random "whore" or "slut". She feels like a person. With a life and I stumbled into it and interacted with them. That's more fun to me.
If I do become a patron of the game, I'm gonna definitely push for more in-depth characters like the ones I'm mentioning here.
And also some vagina sex.
