I'm Meronym (https://linktr.ee/CEMeronym). I've been teaching classes in my local kink community since 2010. You can find more of my writings on FetLife at https://fetlife.com/Meronym/posts/806394. I love teaching kink classes, but not everyone can attend my classes. For some of my classes, I'm providing my slide sets here with some of the conversation that goes along with them (you'll have to supply your side). I suggest you start with Dungeon Essentials.
