As I reached the end of the trail I could see that I was alone. There were no other footprints in the sand. The beach seemed to be empty, just for me.... walked more than a mile close to the sea and threw my towel down on a sandy spot between some large boulders. I kicked off my sandals and dropped my shorts down, knowing that beach was a nudist place. Laying on my stomach I closed my eyes and took in the good sensation of the sun warming up my bare buttocks. Soon my mind went blank as I fell. And I know it's going to be a big one."Oh, God!" I think to myself, "not now!" But it has no effect on what's happening, and soon, too soon, I have a big problem.

It was a bit awkward, but I could reach it and unlock it. Then, with my right arm free, I could unlock everything else. That was the plan, at least.Oh, but that wasn’t all. I wanted to do some self-torture, not bondage-and-lying-around-doing-nothing. First, I made sure that I wouldn’t go crying for help. My house is pretty isolated, but.
