While I don't have personal experience, from her social media and website I might suggest Madame Caterina. She offers multiday prison stays and something called "The Torture Farm" also featuring full immersion, multiday sessions with both indoor and outdoor play

Ah, the infamous Domina Nia. I thought I heard the last of her with the demise of MF. If you are looking for active German mistresses I think that the real deal is Madame Catarina.

she advertised in the domme mags like Fem Dom Mystique and V in 1996, "Ralph Lauren wears them, black and blue marks by domina nia", and she worked at the pandora's box.

I would have gone to her, but she was in the scene less than 1 year, that would make her literally an unskilled dangerous novice in my book.

I chose Ms Leda, who'd been doing it at least since 1991.
