No other man had yet been able to equal or surpass the size of his cock; or his stamina, or match the volume of his cum. He was the alpha male in his circle and as he focused on Kelli, thought that he was about to add another in his string of conquests. The woman had her own thoughts about what she was observing and the way Kelli responded to her man. Both strangers were also nude and in a state of total arousal. The woman rubbed her considerable set of tits and fingered her wet pussy, while the man stroked his huge erection. They had happened on them in the afternoon and had watched the animal like intensity of their lovemaking. The man had focused on Kelli, the woman on Adam, and they never had a clear view of Adams erection, only that the woman responded lustfully, with wild abandon and appeared to be very sensitive and was definitely multi-orgasmic. The woman was sure from watching Kelli that the man was not only built, but well endowed as well. She kept these thoughts to herself. Now, they had returned and found them sitting facing each other, clearly ready to start another session. The firelight provided the perfect backdrop. They were two silhouettes but with sharp outlines and good definition. That afternoon, their own lovemaking had taken on a special intensity after watching these two. On some unconscious level, Adam and Kelli felt that they were being watched, but neither spoke this to the other. Kelli had already decided what she wanted from Adam that night. Now, with the remote possibility that someone could be watching the performance, she thought she would make it unforgettable for them, and at the very least, unforgettable for her. She began by leaning forward and taking Adams swollen cock and licking and sucking on it. She used both hands to stroke the length of his shaft. Her dainty hands together barely encompassed his girth and she squeezed him hard as she stroked. Every now and then, the firelight caught a glint of Adams pre-cum flowing liberally from the tip of his rock hard erection. Although Adams posture was great, there was no way of knowing while he was sitting that his hips and buttocks and thighs were solid and thick with muscle and were covering a goodly amount of his shaft that would otherwise be obvious if he were to stand. Kelly began to squeeze her tits around Adams shaft and to stroke his cock with her breasts. Adams erection stuck out of the top of her bosom enough that she could still lick and suck the tip. Adam patiently fucked Kellis tits and mouth. The man replied, Maybe her rack isnt as big, if I can still see his cock head coming up on top. The woman was silent as she began to understand what she was seeing. She hoped she wasnt wrong and longed for the moment when they would step out from behind the bushes to get a closer look at this new stud and his sexy lady friend. Her partner was getting antsy and was so focused on Kelli, that he discounted any evidence that the stranger could measure up to him. He was intent on making Kelli a new slave to his cock. Kelly sensed the time was right. She kept stroking Adams raging steel pole and said I want your cock to be 16 long and 8.5 around. Adams cock responded and slowly, it seemed to the onlookers, began to grow longer although not by much since Kelli already had him at a pretty generous size to begin with. Adam loved the feeling of growing and getting even harder. He began to stroke his cock with both hands and Kelli helped with her two hands. Kellis breast heaved and bounced with the exertion and motion of vigorously stroking Adam. This kept on for a few more moments with Kelli telling Adam how huge he was, how turned on she was, how sexy he was and how she worshipped his cock. The onlookers could not hear the dialogue, but could see the pace had picked up and that the goal was to have the man shoot his wad. The man smirked, Perfect he was thinking. They were not prepared for what happened next. Adam let Kelli know that he was ready to cum. Kelli said I want you to shoot your load up into the air and let it come down on me and wherever. Dont hold anything back I want to see the most cum you have ever produced. Adam took that as a personal challenge. Kelli knew that would get more out of him than ever before. Even Kelli wasnt prepared what happened next.
