Welcome to the Forum, HS! Thank you for your well wishes, we are all staying safe and healthy over here ?
I believe the "Tall Asian German Mistress" you are referring to is Mistress Sunya. It's been a few years since she's moved on from Fortress though.

I've never heard of klub Berghain. Is it a fetish club? I hope your travels bring you to NYC soon!
