This is an interesting point about the group dynamic. ive had a few experiences of this sort of situation -- multiple Dommes, multiple submissives -- and initially i was concerned about how the interaction would be among submissives ...but it became quite collegial, supportive and affectionate (emotionally, not just the encouraged bi play) ....to the point that the lead Mistress decided to gag us to make it difficult to talk to each other even when serving the group of Dommes...it felt like that was not a conceit but something that for Her was quite important....and so thus quite important for us to internalize...
