Rolled for seduction, Now what?

So I've always had one problem with my kitten... Is that she was hard to discipline. Not that she didn't want it or shied away from it but anything I could think of she enjoyed too much. Being a brat? I'll try spanking! didn't work... impact play has been her favorite from the getgo. We've tried assigning tasks temperature play until it got uncomfortable. But the problem was everything that made these work as a punishment she would enjoy too much and it would feed into it. Now don't get me wrong even while being punished I want her to enjoy herself but part of her enjoyment of being a sub is the punishment aspect of things and It was a place where I was failing. Sure she'd be a bit of a brat looking for a spanking but sometime she will outright just not do what was requested and whats a dom to do? well, I finally got it. It was so obvious. Denial, denial of the spankings and the temperature play etc. When I told her this she told me that I was mean and how dare I use her fetishes against her. Then laughed and told me that she guessed that was the point and it was a hot idea. And it couldn't have come at a better time. She's growing more into her bratty self and has been testing the limits and I have been loving it though unable to meet some of her needs until now. We both discussed it and have found this to be what we were looking for and I'm ecstatic. I love my brat and strive to make my kitten happy and meet her needs and part of that is being able to find discipline that is fair and fits within the dynamic that is fair and meets the needs of everyone.
