After a minute or two, he asked Diana if she wanted to look through the binoculars at the nest he was trying to observe. She couldn't focus the binoculars properly so Michael stood behind her as she held the binoculars and tried to focus them for her. I stood next to Michael and watched as he pressed up against Diana's ass, barely covered by her thin pants. He was wearing shorts and I could see that he was getting hard, his bulge clearly visible. I knew that my wife could feel his cock pressed up against her, but she didn't say anything at first; she just wiggled a little and seemed to press back against Michael's cock as if to urge him on.
For half a minute or so (it seemed much longer to me), Michael stood there, pushed up against Diana as she trained the binoculars at the trees. Michael glanced at me and I gently smiled back at him. I put my hand over my cock which was already hard. He saw me rub my cock through my shorts and then, while still pushing against my wife, he began to gently rub the back of Diana's neck.
Diana arched her back against Michael and turned to look at me. I moved towards her and stood in front of her, looking into her eyes as Michael continued to massage her neck and face from behind. I reached for Diana, held her face and kissed her deeply, feeling her tongue darting into my mouth. I knew that she was very aroused and I could hear her take short, panting breaths. As I kissed her lips and face, I moved my hands down to her shirt, opened the remaining buttons and exposed my wife's breasts. Diana's nipples were erect and hard and, as I reached down to suck on them, she moaned and shuddered as if she was already coming.
Michael had unbuttoned the top of my wife's pants. He pulled them down and let them fall to the grass as I slipped off her shirt. Diana stood there, sandwiched between Michael and me, wearing just her tiny lace panties. She looked so sensual and I was so aroused by her almost naked body. Michael had his fingers under Diana's panties, probing her ass-crack and pussy as I continued to fondle then kiss her breasts and nipples. Diana reached for Michael's cock, unzipped his shorts and let them fall to the ground.
She gasped a little as she took hold of his cock. He was so big, long and thick and at least twice my size. I felt a pang of jealousy and envy but also a feeling of wanting.....wanting to touch it and wanting to see it inside my wife. Diana stroked Michael as he continued to fondle her and then she quickly knelt down in front of him and began to suck his cock, almost feverishly. She held his ass tightly and licked and sucked his balls, all the time running her tongue up and down his big shaft.
