I started to push the vibrator harder in and out of my arse, and in time with the strokes I sucked my eagerly on the cock in my mouth. She again notic...d and was clearly pleased as she started to play with herself whilst watching me and muttering things about me being fucked and her slut. At one point she even started to suck the dildo with me, sharing our imaginary cock.All of a sudden she issued another instruction. 'I want you to wank hard now and cum on this cock, quickly!'. I was so close. Not one to look a gift horse in the mouth we went for a drive at that time of year there was usually backpackers looking for a ride plus usually some fruit pickers moving from farm to farm.We ran up past Renmark with no success and decided we might as well go over to a nudist area we knew of, though not well known we had met some nice people there in the past.We turned off the main highway and headed down to the river there were a few cars parked among the trees so we knew we weren't totally. Both on business, both alone, both bored, both married, both partners sexually disinclined. Artificial formal conversation turned to relaxed smiles and laughter. Then to casual touching of arms, backs, knees. The steady stream of alcohol helped of course. It loosened their coyness and inhibitions. It also helped to removed suit jackets and loosen buttons on blouse and shirt.They moved after a while to one of the comfy sofas. Harry wore a dark grey suit and white shirt. Sally wore a black suit. She wanted it. She needed to cum again, and she was too far over the edge to care. I put my dick back in her soaking wet pussy. She let out a little moan and quivered. Then, she started moving her ass back and forth on my rock hard cock. I squeezed her hips and we got into a good rhythm. She started with her dirty little mouth again, "Oh My Fucking God! Oh Goddamn! Holy Shit!" I knew she was close and I was too. I said to her again, "Make me cum, Bitch!" She said, "Hell Yeah! Cum goddammit!.
