Ok I remember the Danny prompt you are talking about now, and I tend to disagree with that kind of carte blanche blocking (It's fine for major fetish routes, but a main/preferences menu check box would work better and wouldn't rely on people not accidently clicking though text).
I'd prefer a more circumstantial system, if she is being boring or annoying then "the other guy" can have her with my blessing, if "the other guy" tries to crow about it, I want the ability to steal her back or atleast fill her with cum, so the next time he eats her out he gets to know the taste of real victory.
Being locked into a "perma-cuck mode" or "perma-alpha mode" annoys me, I want the freedom to play as my whim dictates, particularly in games that claim to be sandbox. Sure some story arcs demand a certain amount of continuity like the "blue" vs "red" theme, but shit like Darnell trying to mindcontrol Mom is circumstantual, sometimes I just want to sit back and enjoy the show even if I am playing the alpha harem collector, "red" is a little sadist after all, using the Darnell NTR/mindcontrol event to guilt trip Mom into further acts of lewdness isn't outside the scope of that kind of character.
