Soft rope and a safeword

We met in London for a light session: soft ties, a blindfold and nothing extreme. We went over the safeword and the limits before we touched the bed. He tied my wrists to the headboard, kissed my neck and controlled the pace with a calm that drove me mad. Every time I moaned louder he stopped for a second to look at me and check. The contrast between not being able to move and trusting him completely made me come harder than usual. Afterwards he untied me, gave me water and held me until the adrenaline dropped. Good BDSM, for me, is that: power and care at the same time, with no nasty surprises.
