Hi, I've read your comment and found a few solutions to some issues you've been having with this content. Feel free to disregard this comment and move on to another NPC who has content that's more up your alley instead!
1. Instead of self-inserting or assigning a very specific, personal role to your Steele, consider yourself more as "guiding shoulder devils/angels" and the Steele as a person who generates their own thoughts and speech according to general patterns provided by the underlying game code. The PC's five possible personalities in TiTs are distinct but also malleable, and various writers will express them in their own various ways.
2. Don't proc scenes you don't like, and you won't have to deal with the fact that the PC did something you'd never want them to do. Writers here do their best to give good atmospheric hints as to the nature of their upcoming scenes, and its up to you as the player to read those and make your decisions accordingly. Hover over buttons for tooltip hints!
3. Have you considered the possibility that perhaps your PC, during your playthrough of Mirrin's scenes, had a high Submission score? This would explain why they would react "like a sheep" in the presence of a dominating personality, such as Mirrin's. You should be able to check this score in your Codex. (Please note I dont know if this scene actually takes Submission into consideration, but
@SoAndSo has been very prolific so far and I doubt he'd forget such a thing.) If you experience something in game where the numbers don't match up the way they should, you need to file a bug report in
this part of the forum, rather than in the author's thread. The vast majority of writers here don't code their content, so they wouldn't know how to fix it.
Tl;Dr there are plenty of hints in the scenes leading up to the sex that allude to the type of sex it's going to be, and paying attention to those hints will save you from reading scenes that aren't your desired type.
I hope you find plenty of content in game to make up for what's not doing it for ya about this NPC!
