I asked our son to fuck his mother

Carrie and I have been married for 35 years and we love each other deeply. We married when I was 19 and she was just 18 and pregnant. We had only had sex a half dozen times before she got pregnant we were married, but on our wedding night, over about a 12 hour period, I filled her cunt with 12 loads of my cum. She was as up for it as I was. For the next three months or so I fucked her almost every night and talked her into sucking my cock a few times. She didn't enjoy it and really disliked it the couple times I shot my cum in her mouth. When she was approaching her eighth month and getting pretty big, I stopped, as I did not know if it was good for her or the baby at that point. We had a beautiful baby girl. Over the next several years we carried on a better than average sex life, fucking probably around five times a week on average. Almost three years after our daughter was born, we had our son. At that point she had her tubes tied so we would not have a bigger family. We continued a good sex life but I have to admit that it was better for me that for her. I didn't last a long time and she didn't get to orgasm but she still enjoyed doing it. I got a blowjob once in a while and she always finished me off with her hand and made me cum on my stomach. It was only on my birthdays that she would suck me to completion as a special birthday present. Then she would go to the bathroom and spit it out. She never swallowed. We only did anal sex once before she told me that that hole was OUT ONLY! We had been married about five years when I talked her into letting me invite another swinging couple over to spend the evening with us. We swung occasionally for a couple years and even joined a swingers club that we went to a few times. One time I watched her go off with three guys. I wish I could have watched but I was off to another room with a lady beside me. Admittedly, my mind was more on what Carrie was doing than what I was doing that time. After about two years of part time swinging, Carrie told me that she wasn't really enjoying it and said she did not want to do it any more. She said that I still could if I wanted to but that she really didn't want to know about it if I did. I did, but not a lot. About three years ago things started to change. My sexual desire was as strong as ever but my ability wasn't. I stared having fewer spontaneous erections and I would go limp right after cumming and seldom was I ready for seconds that night. At the same time she was changing too. She started enjoying sex more and started having orgasms. Now that she did, I wanted to be sure that she got the most out of it so because I could not fuck her long enough to bring her to climax, I started giving more foreplay. I would rub her clit till she started to cum before I started fucking her pussy. That worked pretty well. Over the last year or so things have continued down hill for my cock. I would not get a full hard erection. It was hard enough to use but not good and hard, even with the little blue pill. Finally it got to the point where I sometimes would not get hard at all. I would still bring her to orgasm without using my cock but I could tell that she wasn't getting what she wanted or needed. I tried toys but she said that a plastic cock just didn't do it for her. A couple times she told me how much she loved me and then asked me if it would be all right with me if she went out and found a hard cock to satisfy her needs. She said that she really needed a good hard fucking, that it was filling her mind most of the time. It wasn't all right with me. I guess I was worried about her finding someone else that she would rather be with and leave me or that she would catch some kind of VD (that was never in my mind back when I was fucking around on her) or that other people that we know would see her out with other men. I thought about it and had just about decided to tell her to go ahead when our problem was solved. I walked into the hall bathroom and our eighteen-year-old son, David was sitting on the toilet masturbating his hard cock. I quickly apologized and left but soon started thinking about what I had just seen. Our daughter, Julie was now eighteen and off to college in a different state. David was fifteen and as I just saw, he was equipped like a man. In my mind I pictured the answer to my problem, if I could get him and Carrie to agree. I would not be worried about her finding another man or be anywhere near as worried about diseases or other people talking about my wife going out with other men. Getting David and Carrie to have sex together would solve all the problems while getting her the sexual satisfaction that I was no longer able to give her. That night in bed, I told Carrie about all of my concerns and the solution that I had come up with. I told her what had happened that afternoon and how I thought that having David fuck her would solve both of our problems. At first she said, "Hell no. He's my son." I kept talking about all the things that worried me about her starting to date other men in order to get the satisfying sex that she needed. Finally she asked, "Do you think he would be interested?" I said that I did not know but I would like to tell him the situation and see what he says. "OK, talk to him." I started to rub her cunt but she pushed my hand away. "Not tonight. I have to think." Even at Carrie's age, she was still a beautiful woman, 5'5" and 135 pounds. Her 34-C tits did sag now but they were still firm and topped with large nipples that still stood out and were easily got hard. She had a little bit of a tummy, but not bad. She didn't shave her pussy and had a thick mat of coarse brown hair covering her still tight cunt. She dressed nicely and turned a lot of heads when we were out. The next afternoon I asked David to come into the den and talk with me. I was nervous about what I was about to do. First I apologized again for walking in on him in the bathroom. "I have something very personal that I want to talk to you about and if it bothers you too much just ask me to stop. Your mother and I are having a problem sexually. I can't get an erection anymore so she is not getting the satisfaction she needs." David interrupted me, "Why are you telling me this, Dad?" I told him to let me finish and it would all be clear. First I asked him if he would tell me if he was a virgin. He paused for a minute of thinking and then said, "OK, no I'm not but I have only done it a few times, why?" "Would you be interested in having sex with your mother in order to help her and me out?" Again he waited a minute before answering me. "I'll tell you the truth, Dad. Ever since I was old enough to know what sex is, I've often thought about fucking Mom. I've peeked at the two of you doing it and many of the times I jerk off, I'm thinking about her. I go on the internet and look at videos of boys fucking older women, thinking that they were Mom and me. Did she say that it is OK with her?" I asked David if he would tell me about his sex life so far. "I first did it when you and Mom were out and Sis and I got foolin around and we wound up having sex." That shocked me. I had never pictured our kids in bed with each other. "After that I had a girlfriend and we fucked twice. You know that I am going with Joann now. We fuck every few days. We've done it a dozen or more times. Don't worry, I always wear a condom." My mind pictured his beautiful teenaged girlfriend on the bed with a man between her legs, fucking her hard, fast and deep. However, the man between her legs was not my son, it was me. I felt a tingle in my balls. I cleared my mind and added, "You would not have to use a rubber with your mom. She can't get pregnant any more. Well, do you want to try it?" "Fuck Ya Dad, I would love to if it's ok." I told Carrie. She was very nervous about doing it but we went to bed early knowing that we were going to see what happens. I started playing with her body, kissing her all over and playing with her clit till I finally got her to react." David was waiting outside our door. When Carrie started to cum, I called to David and he came into the room, naked and with his strong erection leading the way. His mother took a look at him and then closed her eyes. I started kissing her lips and gently squeezing het breasts and David climbed between her legs. His erection was as hard and as big as mine used to be but probably a little thicker. I had her wet so David slid his prick into his mother's cunt with no trouble. As their pelvises met, they both let out loud moans. David started pumping into her and I backed away. I watched, wondering if I was doing the right thing. David was a bull, fucking her hard, deep and fast. With each stroke, Carrie let out a little moan. After about three minutes, she started a hard orgasm. As it built she moaned louder and then in a strained voice said, "Ohhh. That feels so good. Yessss, I'm cumming. Fuck me hard. Fuck your old mom, David. Yesssss!" Carrie tensed up, then shivered and then collapsed. David could feel her vaginal muscles squeezing his shaft as hard as she could. He kept pounding for a couple minutes more before he tensed up and blew a load of cum into his mother's cunt. She had another small climax as she felt his hot sperm pour into her. "David, that was so wonderful. You don't know how much I needed a big hard cock pounding my pussy. Thank you, David. Thank you so much. Come up here and let me suck your wonderful cock clean." He quickly moved up to her head and put his prick to her lips. Her eyes were now wide open and she looked happily into his eyes as she cleaned his shaft. David leaned down and gave his mother a kiss and it wasn't the usual mother and son kiss. Then she pulled me to her and kissed me. David was still hard and he started to get between his mother's legs again but I stopped him and said that that was enough for tonight. David went back to his room and I cuddled Carrie. Before we settled in for a contented nights sleep, she looked at me and said, "That was wonderful. Did we do the right thing?" "Yes," I replied. The next morning, we all sat at the breakfast table. I looked at them, "Shall we talk about it. Carrie, did you like it?" "Yes, I did. I was really nervous about it but it was wonderful and I'm glad we did it. Was it OK for you, David?" "Mom, it was better than I had ever dreamed about. It felt so wonderful to be in you. I could have kept doing it all night. Will we be able to do it again?" We all looked at each other and at the same time said, "Yes." The three of us have been spending two or three nights a week together in bed now, as a family, for about three months. Some nights David stays in our bed all night rather than going back to his room. When he does that, I feel them fucking again in the middle of the night, maybe about two or three in the morning. I just smile to myself and don't let them know that they woke me up. Carrie sucks my limp prick while David fucks her slit. Now, she lets me cum in her mouth and she swallows because she is to busy getting her pussy pounded to orgasm by David to stop. David is often not satisfied with filling her just once. He usually goes a second time and maybe a third. Often if he goes for thirds, his third load of cum ends up in her stomach. Everyone seems happy with our arrangement. We tried to get David's girlfriend, Joann to join us to see if that would help me get a useable erection but they broke up when he asked her. Our daughter is due home for a two-week break from school. We are trying to decide if we should just quit while she's home or if we should try to get her to join us. I'll let you know what happens if you want to know. 1211
