Tl;dr - seeking ideas/stories & recommendations for resources, communities, mentors, or subreddits specifically geared towards non-hierarchical poly D/s relationships.

I'm a Master to my romantic partner and collared slave of 3 years, and the slave also has another Sir. I'm close and flirty with this Sir as a metamour, and the three of us play together on occasion. I also have a long term partner who calls me Daddy. We all practice Kitchen Table & non-hierarchical polyamory.

I haven't found any other people who practice non-hierarchical M/s dynamics wherein the slave is free to have any other relationships it pleases, without the Master's permission.

If anyone else is in such a dynamic, I'm curious to hear stories of how do you manage the balance of ownership in the M/s dynamic, with non-hierarchy in your poly dynamic? How you relate to your slave/sub's other Master/Dom(s)? How do you manage balancing the time your sub has to do the tasks you assign them, with the tasks their other dominant assigns them? What kind of communication channels do you keep open with your metamour-Dom?

I don't have a specific "problem" I'm trying to solve. (Things are actually great in all of my dynamics.) I'm just looking for ideas and stories to help me farm new ideas I might not have thought about.
