So we began an affair. There was never much pretence that this was romance. It was never much more than a sexual relationship, and an exploration and enactment of each other's fantasies.
Very early on we decided on a dirty weekend at a coastal town not far south of Sydney. The excuse was a Jazz Convention, held there every year. We arrived on Friday evening after dark, and booked into the first motel we came across close to the park where most of the Jazz Bands would perform.
In the morning, still not quite light, and with Diana still asleep, I got up and dressed into my jogging gear and set out for about an hour's run. When I got back to the room, it was bathed in light, and Diana was lying provocatively naked on the bed. She ordered me to quickly get my clothes off and join her. Being covered in sweat, I suggested a shower first. She was insistent that time was of the essence.
Obediently I disrobed and lay down naked beside her. I could now see where the light was coming from. Straight ahead of us was a large window, and the sunlight was now streaming in. Diana had opened the curtains when she woke, and I had gone running. I could look straight out onto a staircase, that worked its way out from the building to a platform, and then led back into the deck that surrounded the floor above. Anyone standing on the platform, or below, could see straight onto our bed, and our naked bodies.
"He's coming" she whispered excitedly as we heard footsteps above. "I knew he would come again."
As his feet came into view, she leaned over me and took my cock in her mouth, as she jerked me off feverishly. As soon as I was erect, she straddled me, with her back to our voyeur, and eased herself onto my cock. She then kind of moved me with her body so that we lay at more of an angle across the bed, to afford him a better view. There was a narrow band of cloth across the top of the window on the curtain rod. This prevented our eyes from meeting. She worked her way up and down on my rod, occasionally looking straight at him to ensure he was paying attention.
When I ejaculated, she got up off the bed, with cum dripping down her leg, and onto the floor. Staring at him, she reached between her legs with her hand that she then smeared across the window. She then reached out for the curtains, closed them behind her, and then came through them, walking to our door to lock it.
On another occasion, we were at a harbourside beach (Obelisk) which was an unofficial nudist beach. It was getting later in the afternoon. We had been to lunch, had too much to drink and decided not to go back to work, but to cavort a little in the nude. The beach was quite close to her place. The beach faces due east, with a high hill (Commonwealth Government property) on the western side. The sun therefore came off the beach early. To get its last rays we climbed onto a large boulder, and lay on it. The rest of the beach-goers had left for the day. Immediately we were attracted by very bright blinking off shore. There was a small Navy vessel, virtually at a standstill, close to shore, and we could easily make out two Navy sailors, in white caps, shirts, shorts, long socks and shoes, each with binoculars trained directly at us, standing on the deck of the craft. The sun reflected in the binoculars had caught our attention.
Diane immediately repeated her performance from the motel, but this time she faced them directly as she worked herself up and down my shaft. All the time she waved enthusiastically at our spectators who, after a while, waved back.
