These all have the same problem of implying a low preference score, which is already an issue with Anal Slut.
I don't really have
data on this, but from anecdotal evidence, that's pretty much not true. Most women (and men!) don't really want anything to do with the back door, never mind limiting themselves to
only that.
The game is, of course, escapist fantasy and we can have whatever we wish in it.
But you
were told, via trait descriptions and small blurbs telling you she seems to both love and hate it now. It was
subtle, that's true.
That's already kind of a thing. It's what the 'refuses' condition is supposed to be.
We already had the discussion that such a mechanic needs to be
communicated to the players somehow, and the main ways to do that in the game are stat numbers, titles derived from those numbers (including 'refuses', 'reluctant', 'Skilled Stripper', 'Rank X', etc), and traits. And Goldo deliberately removed the 'Stairway to Heaven' to make a brothel-focused game.
There are several ways you could accomplish this. Perhaps the most hardcore would be to copy the 'locked fixation' mechanic to preference scores, make an 'absolutely refuses' version that never improves no matter how hard you beat her.
That would, of course, come with its own communication issues and would clash with how the game generally treats reluctance, i.e. that it can
always be overcome with some effort.
Another is Bonanza's 'fixation-locked' preferences, which would softlock your girl into refusal until you remove the fixations and/or increase your/her stats/rank pretty heavily.
This is supposed to be based on some kind of obedience mechanic. She obeys, because shes's a good little slavegirl, not because she likes it.
Now, you might disagree with this. I did, and added checks which made everyone at 'very reluctant' or 'refuses' always scream their heads off. But I doubt Goldo wants to do that.
Yeah, the fact that even rape mostly increases preferences fucks with that. You need a 'dom' personality to resist liking the invading dick(s).
Basically, the game isn't really set up to be a hardcore slave trainer. You could, of course, change that. I did, although I didn't focus on mono-act girls. Some people liked it, some didn't, and the whole thing was a lot of work. That's how it is, good stuff isn't free.
I will repeat once again, if you truly wish something as specific as that in the game, you need to either do it yourself or
personally convince Goldo or some modder (_neronero, most likely
). And Goldo doesn't read this forum.
