In this artist's previous work (marie and alex), they didnt exactly follow bdsm etiquette but they were respecting each other's boundaries if it's any help
Well the first one to come to my mind is "My Partner's Tastes and Fetishes". It incorporates safeword, aftercare and discussion of kinks ^^ 1Penny4YourThoughts
Is it too much to hope that the bdsm in this actually follows proper bdsm etiquette?
