Over time, there has been so many, many things. My Master has always been my ‘go to’ expert. I guess the thing that I’m most curious about presently is how a sister sub works. I understand the concept to be two subs who are under the same Master. One sub is usually over the other sub. According to my Master, it is the Master’s responsibility to make sure to take care of each sub, oversee the dynamics and ensure all goes well. I am curious as to how it could work. I see the possible fantasy of a Master having two subs, but their getting along, minus jealous issues seems so difficult!
