Thanks for commenting - it's encouraging to know that some of my readers enjoy the femslash I'm doing. It's the first time I've tried to write anything with even a hint of D/s, but I was intrigued by what I've read elsewhere by those into BDSM about the power of the sub. I liked the thought that Irene can only control Kate because Kate chooses to do what Irene wants - but not all of the time. And the thought of Kate as the practical implementer behind Irene's complex plans.
