I'm not big on reading BDSM fanfiction (this is actually the first story I have made my way through entirely) but this was very good! I don't really get the appeal of Dom/Sub life (can't quite wrap my mind around the Sub situation but I can understand it a bit more from the Dom side), having no experience or knowledge of that way of life, but to each their own! There is something intriguing about the way you wrote Gibbs and Tony. I think you were very good at keeping them in-character and while I may have skipped a few of the more BDSM-heavy parts on the whole I quite enjoyed reading this. You are a very, very talented writer and now I shall go read your other stories!
