I'm part of the anti-NTR crowd. I don't really care about my love-interests having to strip in front of others, at least in the context I saw where it was part of that party game. The examples you provided of fooling around were again all part of the game, and didn't really come close to setting off my NTR aversion. While I have zero interest in experiencing NTR to the extent that my love interests are performing actual penetrative sexual acts with other men, I'm okay with NTR being either an avoidable option, or the price of failure in a game. I'm also not opposed to "incidental" NTR-ish stuff, such as what you've described, if it makes sense for the story, and again, isn't there specifically to be NTR. That entire party scene unfolded as I expected something like it to play out in real life, and honestly I had fun with it and seeing how both my stats, my mind control power, and how I played the game in general affected the outcome and ultimately left me in control of the sex.
