We had been been out sailing for a few hours before sunset. She had worn the tiny bikini I had bought for her last week. She was still uncomfortable with the exposure, but she was beginning to understand how important her exhibition was to the role she had selected for herself. We sat together near the tiller, the sails down and a small anchor holding us in the lee of one of the small islands that dotted this man-made lake. The sun slowly edged its way below the horizon with a blaze of oranges fading eventually to blues and finally deep purples. We nuzzled and cuddled as lovers do, content to simply be close. Finally when the last light had vanished from the sky, I stroked her hair gently and looked into her eyes as I untied the biking top that almost covered her. She made no effort to move but simply waited. My fingers brushed the ends of her nipples as the night air made them crinkle and harden. I pulled her up by her elbo and positioned her so that her stomach lay across the boom. The ferled sail made it a little more comfortable than it might have been. I quickly stretched her arms straight with some soft cotton covered nylon line. One of the nice things about sail boats... lots of soft rope. I ran my hand gently across her back and then across her still covered buttocks. She shuddered at the contact but stayed still and quiet. She had only submitted to me the week before, but she had an uncanny sense of what I wanted. This was but one of the things that made her so very special. My hands slow ran up her legs stopping at the tiny bows holding her bikini bottom in place. I slow pulled and her last covering fell to the deck. I used two more pieces of line to immobilize her legs in place. Sail boats have such convient places to secure ropes. I ran my hands up her legs again, dipping into her wetness only for a second. My hand was soaked from the brief pause and I move around in front of her so she could lick my hand clean. I went below, steading my self from the gentle rocking of the boat. I opened the seat in the cabin and took out the leather barber strap we had found while antique shopping just the day before. Her eyes had glowed when she first picked it up. Now we were going to use it the way she wanted. I climbed back up on deck and made sure to move where she could see the strap in my hand. With my free hand I stroked her cheek gently and then brought the strap to her lips. She kissed it with the intensity that one reserves for a lover. I ducked under the boom and positioned myself behind her. I used the strap to slowly stroke her legs and then her buttocks. Touching her gently with the wide strap. Still she stayed quiet. I moved back just far enough to swing the strap freely. I aimed for the nearest cheek first. The swing made a swishing sound followed by a firm crack as the flat of the strap hit. A bright red band appeared on her skin. The next swing was aimed at the other side. It too made a red band. I slowly covered all the skin of her ass, being careful to stay below her spine and working a little way down the backs of her legs. As I layed on the last few strokes, she broke her silence with throaty moans. I slowed a little to be sure they were not moans of pain. With the last stroke, I could restrain myself no longer. I pushed my speedo from my body and plunged myself into her with a violence that frightened me for a moment. The warmth of her glowing red skin inflamed me. With only a few thrusts I shuddered and came, collapsing atop her for a moment. When my head came closer to hers, I could her her whispering over and over. I had to move around to her head to make it out clearly. She was whispering over and over, "I love you."
