Female led relationships discussion

I picture myself in a dreamlike state, attending to a Mistress who keeps several slaves, where I must share her attention with others just like me. The prospect of belonging to a Woman who also owns multiple subs and slaves appeals greatly to me. I would enjoy interacting with them according to the hierarchy my Mistress sets out, or however else she sees fit. Beyond the practical aspects of real life, I am eager to hear your thoughts on the concept of a Slave Harem.
