That was what I thought you meant Clairic...but, who am I to second guess the one true Bondage Master here? I did believe it was people in the story voting on what happened to her. Much like 'live bdsm internet shows' available to view and send in requests to what happens via chat.
Again, I tried several different searches and haven't came up with much...hmmm, does that mean I may have yet another avenue for a story? May have to see.
Anyway...I will keep my eyes open and, again, hopefully there may be another member who remembers reading something like what you are describing.
