I couldn't help myself, I just had to do it. The sun felt so good on my naked body, the only other people around were solo men, and they were all hard. Some of them were masturbating openly while looking at me, others furtively, stealing the occasional glance in my direction and quickly removing their hands from their cocks if I started to turn their way.
I sat up, and started brushing the sand off of my body, paying special attention to my nipples, as if there was a lot of sand adhering to them. I then held each breast, one at a time, with my hands, lifting them up, as if I was checking to see if any sand had accumulated under them.
After having attended to my breasts, I moved my hands down my stomach, then skipped down to my legs. I spread them apart as I brushed them off, and spent a long time brushing the sand out of the creases where my thighs meet my body. I then moved up onto my knees, and started to brush the sand out from between my cheeks, looking between my legs as if I needed to see if I had missed any.
By this time I noticed that the men around me had become more attentive; those who were openly pleasuring themselves had actually turned in my direction so that they were masturbating towards me; had any of them cum at that moment they would have erupted in my direction. One man had moved back against a cliff wall, and was standing up; he had one hand holding his balls, while the other slowly stroked up and down on his very large and very erect cock. His eyes never left my body. The onlookers who were shyer were now glancing more frequently in my direction; one man had put a towel over his lower body as if that could conceal the obvious stroking going on beneath it.
I delighted in the sensation of turning all of these men on, and proceeded to the next step.
