To be fair, we have no idea what happened in that bedroom. All we know is that, presuming you said yes, the Inquisitor had their hands restrained for, like, point two seconds before rather breathlessly agreeing. Then the hands were let go, and he pulled you close.
That's it. And, yeah... that's pretty okay to me? It's not like he whipped out riding crop and gimp mask before asking you first...
I admit, I may be overly critical on this issue because there are so many people who have no clue but think they do because of "insert popular media here". Every couple of years a book or movie comes around that gives people ideas but no actual knowledge. As a result you see an increase of special injuries in the ER, of people getting stuck in cheap handcuffs and, sadly, people who need counseling.
What many people don't understand is that these things don't have to be physical. There is a lot going on mentally, too. It's a common tactic of ******* doms to find and exploit weaknesses, to instill doubt and to tear someone apart, so they can rebuild them to their liking. I've seen traces of that in IB and how he talks to the Inquisitor later on.
The consent thing... uh. You may be really into something, enjoy it tremendously... but if it is done to you without you getting a chance to say yes, then it's still bad. Even if you enjoyed it. I can think of a few examples but I'm not sure if that would still comply with the rules of this forum.
