A line marriage was just that, a marriage of men and women of different ages that continues as younger partners joined the older members of the marria...ge. I was still emotionally thinking of the old one man-one woman unions of the before time.I bent down and kissed Rita. She was right and I was wrong. I 'tasted' the emotion coming from Rita and knew she would fit our marriage perfectly. In a wondering voice, Rita looked at me, "You really do want me in your marriage. I can feel your acceptance. I was being asked lots of questions about what they were allowed to do to me and where they were allowed to cum. Just reading the replies was making my pussy wet and I replied to the ones I liked the sound of. one guy in particular took my fancy and I arranged for him to come round that night. When I opened the door there was a nicely dressed, 40 something guy standing there. He was ordinary looking and seemed quite relaxed and I was sure that this wasn't his first time paying for services such. Strangely I could not stop and deep inside I wanted him to take the initiative.His eyes were closed and mine hovered between his legs. Underneath the shorts, there was a man’s penis which I had jerked off only an hour ago. He was well hung and the images of his rock-hard penis in the bathroom were constantly bombarding my mind. I was getting turned on by my son!The dilemma was whether I take some initiative or let him chalk the path? I decided that I should let my son take the lead like a real. So she climbed on top and at that same time in the story I had her slide on top of me and let my hard cock press between us, just like what was happening in the story. I described the uneasy feeling that she felt at first. How she really just wanted to get warm, but that feelings were conflicted in her with thoughts of being safe, not cheating, staying warm, and how I said it was okay to be there and even suggested it. It was a struggle, but the struggle was occurring as they both continued to.
