Tied Up Surprise

My husband surprised me last night by tying me up and blindfolding me. He made sure I was completely at his mercy before bringing out all kinds of toys and spanking paddles. The sensation of the paddle on my bare bottom sent waves of pleasure through me, but he wouldn't let up until I begged for relief. When it was over, we spent hours exploring every fantasy together that neither had dared to speak about. How do you handle a sudden desire to explore BDSM with your long-term partner?
