@MandyXMarxxx I'm not sure about dungeons besides one thats called Refugium, but there are dungeons/"rooms" to rent and they're pretty indeed! I can give you some links for them if you're interested, maybe you can dm me(?)
@MandyXMarxxx maybe dreams do come true.. how about Hamburg? pretty big bdsm/femdom scene! but I'd also travel across the country to witness a session with u
