Our first time in public was at the nude beach at Kambah Pool in Canberra. I was caressing my partner in the sun and started to rub some lubricant into her cunt. She was loving the freedom and had never had sex in public before. I worked my hand into her and was gently fisting her cunt when we got an audience. It was another guy about our age with a very erect cock and a very curious mind. He wanted to fuck my partner but that was going too far for us. We let him tickle her clit while I was fisting her. His cock was too tempting for me so I started to pull him until he came. That was enough for him and he left. We were then joined by another curious younger guy with a huge erection. He wanted to watch and was also very interested in my partner's glistening, shaven cunt which by now was very swollen and red. I thought it would be good if she could feel how big his cock was so I guided her hand onto his cock and she rubbed him for a little while until I took over and pulled him until he came. That was enough for me and I had to come so I put my cock in her cunt and came in seconds. It wasn't what I wanted. I wanted to fuck her for a while so the others could watch but I couldn't help coming.
