Highly recommend the experience. Each Mistress is a unique gem, and together --watch out. I had a wonderful time, in spite of an "interruption" soon after we began ( oops). In fact it made it better as we sat for a few minutes and I talked to them as people. I think that made the rest of the session work much better for me. A little bit of real familiarity adds to the feelings, don't you think?
The Fortress is amazing. The Tatami Room was very nice and small -- a point that makes it highly recommended in my book -- can't run that far to escape and it is very cozy.
The worst thing I could say is that I had to wait in the shower a little while as Mistress Seung and Ahn got a towel for me, but even that wasn't bad as I kept myself busy scrubbing away (I bet they are smiling now if they are reading this -:- )
Hope to get back there someday.
