To the west about 300 feet away was a couple, both sitting up on their blanket. I noticed them watching us discreetly as Barb undressed. Barb laid do...n beside me on the blanket and got out the suntan lotion. I immediately offered to help her with it, she responded by handing me the bottle and rolling over onto her stomach. I sat on her thighs, straddling them, supporting most of my weight on my knees on the blanket. My semi-erect penis basically lay in her butt crack. After shaking the lotion. Lisa is a corporate lawyer and I am asoftware consultant and have my business in our home. We were doing our best not to grow into the typicalmiddle age couple. Lisa was a perfect wife to bemarried to, a statuesque 5'8" blond with a flawlessfigure that always turned the crowd's head. In heelsand hose her legs would make Jamie Curtis jealous. Her natural C-cup breasts and heart shaped ass stillgave me a hard-on at the most inappropriate moments. I was a little smaller than Lisa at 5'7" and. I gave one last thrust, burying my cock deep into her asshole, and shot the largest load of my life into her colon. I released her ankles, and collapsed on top of her, my cock still lodged into her asshole. She whimpered as she tried to roll away. I didn’t try to stop her, and my semi-limp cock slid out of her asshole with a wet sucking sound. Jeni rolled onto her side and resumed her fetal position, sobbing softly into a pillow.After catching my breath, I got up and looked at the damage. But the phantasy doesnt let me be. In the past i never dreamed about it but nowadays i very often have dreams there i watch her fucking another guy. I wake up unbelievably aroused go to the toilet and jerk off, (one time i woke my wife up and fucked her)and after that i hate the phantasy get jealous and angry about myself. The problem is not only the jealousy. There are more problems like our word not permitted and the risk to lose her to another guy and our background and especially religion..
