So that Natasha Romanoff backwards interrogation techniques? Let’s throw garbage at that.
Obviously, she learned that in the Red Room. Except her Red Room handlers didn’t give a shit about her wellbeing or it was another way from them to train her to withstand pain and she had to go through the whole interrogation, not just till the things got bad. And more often than not, it included rape – either as an another tool to subdue her/humiliate her or just some goons got bored. And through that Natasha learned to enjoy it. She doesn’t really like sex after all that but being forced to do it against her will instantly turns her on.
In the present day Natasha tries to opt out of her “backwards interrogation” before the things go south. But let’s say something went wrong and she can’t get away and the interrogator (who’s that is up to you) decides to rape her. And to his delight and Natasha’s horror, she gets really aroused at the idea. And I don’t mean just her body reacting against her will – she really, really gets off on that, even if just the thought of it makes her sick to her stomach. It’s still non-con since Natasha doesn’t want it to be happening and she has no control over that but she can’t help but enjoy it and orgasm. A lot.
