I'm very happy my words were so vivid for you! *wriggles in delight* It was so fun to play with this kink (useful exercise for another fic I am working on) and I tried to focus on sensation and how to describe it, so I am very happy you enjoyed it so much~

Trust is the heart of bondage. It's the most satisfying when the parties involved trust each other so absolutely that one can give themselves over to the hands of another and know they are in a safe, pleasurable place. And I feel that Fai and Kurogane have this level of trust now, so they can do that for each other. ♥

That, and I think Kuro-sama really is sexy trussed up in red silk rope. *shivers delightfully*
