Oh how fun! I so appreciate how my D for the Spanking Romance Review Spanking A to Z challenge also works for the Dungeon Crawl! So I talked more about treatment of marks in my Vala's Story serial, although I also touched on Kathryn Blake's spanking romance "Acting Lessons."
So yes, the damage of impact play is something I think of as a BDSM-er. I find the variety of skin damage possible from BDSM activities to be more varied than "just spanking." Although thankfully reading more spanking fiction has educated me on just how varied even spanking- limited to the buttocks and upper thighs- can mark the bottom's body. While I'm still pondering what to say in a review for Kathryn Blake's "Acting Lessons," I was intrigued that the spanker in her book didn't want to leave serious marks and would use peppermint oil (if I'm remembering right) to lessen the chance of bruising, marks etc. In my own writing, I've used several different preparations, even taking the time to match different remedies to a dom's personality. In Vala's Story, just to name 3 people- Simon prefers Arnica, Iona prefers aloe, and Raanan prefers lavender cream. I've also read people using cocoa butter and coconut oil.
