As I said above, I think it is depicting something true to life. Since it is in reference to the kink and not the art, I think you can probably use your own art style, just the kink itself has to be true to reality? So the positions being something actual people can do; fluids and the like in realistic amounts; or showing the gear and/or bondage true to what people actual use?

Whizzy said they are open to interpretation. I hope this helps you jump start figuring out how you'll interpret it.
