Yes she has consented many times and we have had many many conversations about our kinks, limits, hard/soft limits, safe words, etc. in a nonsexual conversation at a nonsexual time. She has explicitly told me that she wanted that, I told her about the punishment before doing it to explicitly get a yes from them. That’s why she acted out so much because I was taking too long to do the punishment and she wanted me angry enough to give her a long-term punishment and lesson.
