Are there any reference materials (pod cast, movie, shows, etc) that can be used to help get the vibe right?

Anything that it can be compared to to help get in the "headspace" for it? 

Are there any play throughs available?

Etc etc

Very interesting question. From my perspective (author), I tend to push for something fairly Sunstone adjacent as my guiding star. I find Stjepan Sejic provides heartfelt characters with whimsy and real stakes all blended together in a way that I try to bring to my kink related material. But the book also strives for epic fantasy fun in line with D&D's traditions, so throw in a healthy dose of that as well.

Really, it's a vehicle for you to tell your stories in whatever vibe resonates with you. Be that grimdark, erotically silly, or anything in between.

For playthroughs, I'm not personally aware of any, though would love for people to link me to any that might exist.
