I am guessing the special NPC's are hard coded in a way there is no varying the way they act.
I am trying to make the Admirer more aggressive. Most times I can if I change his inclinations. I got him at Forward, Bully, Dominant Vibe, Taker, Sadist, Breaker, Dominant using the cheats. And in most ways this works. He resists my resistance to him. Except... when I ask him not to penetrate he apparently reverts back to his insecure nature and immediately relents. Can't figure out any way to change that. So I am guessing that part of his personality is indeed hard coded.
As an NC mod idea, I thought maybe where there is a roommate in the apartment or dorm, they both conspire to get me drunk or horny enough that one gets me drunk or tied up or something and the other roommate appears and they both strip me and take turns with me. Just a thought in the wee hours of this morning.
