This is Joan's story as she told it to her son Steve, after he stumbled on his parents in a wild sex orgy late one night in their home. When I was 15 and John, your dad, was 17, he started taking me out. We would go to movies, parties, plays, circuses, but the real excitement of the evening was always the sex that we had in the back seat of his father's car before he drove me home. We were using condoms, but one night we ran out of condoms and we both wanted another fuck, so we fucked without any protection. A few weeks later it dawned on me that I had missed my period and must be pregnant. Soon after I started vomiting up my food. That settled it! I was pregnant! Oh shit! I told John. He suggested that I could have an abortion, but I said that I wanted to have his baby. We both decided that we wanted to keep the baby. He told his father, who suggested that I should have an abortion. When John convinced him that we both wanted the baby, he called a family conference with John and me, John's parents and my parents. My dad suggested that I should have an abortion. My mum asked why we did not use contraceptives. After some pretty heated discussion it was agreed that his parents and mine would contribute to support us. We would get married and have the baby. John's father was anxious that John should not be set back scholastically. Since neither of us ever went to church, we married in a registry office, and moved into a cheap house: one bedroom, kitchen, living room, bathroom. It did have a private back yard, with a small, above ground swimming pool, and a shady back veranda. I went to school for the rest of the year and passed all my exams. John did very well in his final school exams and qualified to study law at university. By the end of the school year my breasts were bigger and did not fit in any of my bras, so I stopped wearing a bra. My belly swelled so my panties did not fit, so I stopped wearing panties. Those last weeks, going to school with no bra and no panties made me feel very horny. Fortunately John was there to fuck me every morning and every night. When school finished the summer heat started. Our little house had no air conditioner, so I spent most of my time totally naked in the back yard. Every so often I would climb into the pool to cool off. Then I would climb out and lie in a recliner, without drying myself, and read one of the books that John had recommended. John took a summer job to augment the allowance that our families were giving us. When he arrived home each evening he would find me still naked and fuck me wildly, right there in the back yard. For Christmas we went to my parents for Christmas eve and to John's for Christmas day. I wore a piece of cloth wrapped around my body and tucked into itself under one armpit. Both times John mentioned that I had not worn a stitch of clothing for the past two weeks. Both mothers expressed their disapproval, both fathers grinned and said nothing. On boxing day John and I were relaxing in the backyard. Since I was always naked, he decided that he would be naked too. Then my dad turned up, unannounced, mid-morning. I greeted him and gave him a hug and a kiss. He hugged me back, longer than was necessary, then told me how much being pregnant suited me; it made me look even more beautiful. I fetched beers for dad and John and iced water for me and took him out to the back yard for a chat. He commented that we were so much more relaxed about sex and nudity than his generation. We discussed names for the baby, without deciding anything. We invited him to take a dip in our pool, but he declined. After he left I asked John, “What do you think dad wanted?” “I think that deep down he wanted sex, although he probably would never admit it, even to himself. He spent a lot of his time here staring at your body. His prick was erect the whole time that he was here. My guess is that he is not getting any, or not enough at home. I'm pretty sure, from his attitude to your mum, that he still loves her and would not want to hurt her, but at the same time he would love to get a little action on the side, if it were safe.” “So?” “I think that the next time that he comes here you should give him a surprise blow job.” “What! He's my dad, for Christ's sake.” “We are going to need the allowance that he gives us for a few years yet.” “That makes it sound like prostitution, for fuck's sake!” “Let me explain my theory of love and lust. I love you and I believe that you love me. We also lust after each other. I admit that I lust after anything with two legs, two tits, and a cunt, and I have seen you looking at some of my footie mates with clear lust in your eyes, but your father loves your mother and lusts for you. What could be the harm in offering him a welcome release?” “Oh dear! You make it sound so reasonable. But what about you? Wouldn't you be jealous if I started giving my dad what he wants?” “Providing that I was watching or you told me all about it, no, I don't think that I would be.” That afternoon we had lunch, a gentle fuck and a swim and were sitting out the back when John's dad arrived unexpectedly. I greeted him at the front door with a hug and a kiss. When, instead of breaking the hug, he held me to him with a firm grip on my bum cheeks, I decided to put John's theory to the test; I stuck my thumbs in the waistband of the shorts that he was wearing and pulled them and his undies down to his knees. His half-erect cock ended up between my naked thighs. The look on his face was classic; his lust was fighting with his fear of what his son would think of him and me. “Relax, pop!” I had never called him 'pop' before, but in the light of our developing relationship I thought it appropriate. “John says that he and I love each other. But he lusts after any female within 100 m, and he thinks that I lust after any male near me.” “And do you, my dear?” “Only if they are good looking or rich. You qualify on both counts.” “You flatter me.” “Anyway, John says that maybe you love your wife, but you lust after me. He says that it's OK for me to give you some pleasure provided that he is watching or else I tell him about it afterwards.” Without further ado, I dropped to my knees in front of him and took his, now erect, cock into my mouth. I had never been able to deep throat John, but somehow, perhaps because pop's cock was a little bit thinner, I managed to take him right into my throat. While he was in my throat I tried humming, and that seemed to do the trick; within minutes he was cuming direct to my stomach. After that, we went out the back with beers for the boys and chilled water for me (because I was pregnant with you), and sat and chatted. Pop said, “John your theory that love and lust can be separated works for me. Did it upset you, watching us?” “No, pop, if you had looked at me while Joan was blowing you, you would have realised how aroused I was watching you two.” John had never called his dad 'pop' until then either. “However, I don't think that your mum would understand.” “Don't worry, we will never tell her, or anyone else, will we Joan?” “Of course not.” Pop had left his shorts and undies where they fell and was sitting there with us in just his T-shirt. When the beers were finished, pop decided that he had better get home before he was missed, so he gave me a farewell hug and kiss before he put his shorts back on. “I hope that I will be welcome back sometime?” “Of course! Whenever you feel the urge!” As soon as he left John grabbed me and kissed me passionately, then pushed me down. I realised that he hoped that I could at last deep-throat him. It was a bit more difficult than with pop, but I did manage it. Again, all I had to do was hum to make John cum almost immediately. Then he dived into my pussy, stuck his tongue inside my cunt, then sucked on my clit. Again the erotic activities of the day had made me so horny that I came within minutes. Outside again, with another beer and another iced water, I decided to explore John's theory of lust and love further. “So, John, what are the limits of your love/lust theory? Apparently it's OK for me to give dad and pop blow jobs. But what about you? How do you satisfy your lust? And what if dad or pop wants to fuck me?” “Well let's explore how we both feel about things. How would you feel about watching me fucking someone else?” “I don't know. Until today I could not imagine giving anyone a blow job with you watching, yet now I feel quite comfortable with that idea. It helped that you were so enthusiastic for me to blow you after pop left, and your eating my pussy was even greater.” “So, lets take it one step at a time. If either of us finds that it is getting too heavy, we should agree now that we only have to say 'stop' and we will both pull back to what we are comfortable with. Your fucking your dad or pop is OK with me, provided, as I said before, either I am watching, or you tell me everything afterwards.” “That sounds good to me. Now I'm quite excited about watching you fucking a beautiful young thing.” The next day John had to work, so I was alone and naked as usual when my dad turned up unexpectedly. I greeted him again with a hug and a kiss on the lips. He pulled my body against his and just held on to me by my bum cheeks, just as pop had the day before. After a few minutes like this I decided to take the initiative; I pulled his shorts and undies down past his knees. They fell to his ankles. “I think that you really want to fuck me, dad, and I think that I would like that too.” “I couldn't do that! You are my daughter and John's wife. What would John say if he found out? And what about your mother?” “No one will ever tell mum. But John seems to want me to become a slut and I am starting to like the idea too. Besides why else is your cock so erect in my hands if you don't want to fuck me?” Well, he had no real answer to that so I pulled him by his cock over to the lounge chair, then lay down and pulled him on top of me. Unfortunately I did not feel much from this first time with my dad because he came very quickly in my cunt, then went limp and slipped out of me. “I can't believe that I just fucked my teenage, pregnant daughter!” “Well, I hope that you will fuck me again sometime soon.” “I'm sorry I did not last long enough to give you an orgasm this time. I haven't had a fuck for about 2 years. I hope that next time will be better for you.” “Why don't you and mum do it any more?” “I don't really know. She just lost interest, I think.” “John fucks me every morning and every night and it is still not enough.” “Maybe that's why he wants you to fuck me? Because you're wearing him out?” “No, I don't think so. I think that the idea of my fucking someone else turns him on.” After dad left, I rang John at work and described my latest fuck to him. He was pleased with me. “You've become a real little slut almost over night. I'll have to think about a reward for you for tonight.” When he arrived home from work he was carrying a big bunch of flowers. I was hoping that my reward would be something more erotic, but I thanked him and arranged them in the only vase that we had. But he was acting strangely, he refused to fuck me, saying that he wanted me to be really horny later on. After we had eaten, we were sitting together, naked as usual, watching some crap on TV. When the door bell rang John went to answer it without bothering to cover his nudity. He brought back into our living room, his mate Brian and Brian's girlfriend Sue. Brian had on board shorts, and, I guessed, nothing else. Sue had board shorts and the top half of a bikini. Brian and Sue saw that we were both naked and immediately discarded their shorts and Sue's top. Meanwhile John came back from the kitchen with 3 beers and a soft drink for me. He had Sue sit with him and Brian sat with me. We drank our drinks while John embarrassed me by describing, in great detail, my recent sexual activity with pop and dad. I needn't have felt embarrassed however; Brian's reaction was, “What a magnificent slut, you've become.” and Sue's was, “Wow! Awesome!” Then I was surprised to see Sue take hold of John's cock and start to stroke it. I was even more surprised when John responded by squeezing Sue's nipples. Next, Brian placed his hand on my swollen tummy just as you decided to give him a mighty kick. He grinned at that and pulled me to him and started to kiss me. Finally the penny dropped; this was John's idea of rewarding me, this was what John wanted me horny for. I returned Brian's kiss, enthusiastically, and griped Brian's cock which quickly became fully erect. Before I knew it, I was straddling Brian's lap, facing him, with his cock pressed between my labia. I reached down and positioned his cock at the entrance to my cunt, then scooted forward so that he entered me. As I did this I heard Sue and John moaning, so I assumed that they were doing something similar. Actually I found out a little later, after Brian and I had come as Brian fucked me, that Sue and John were doing something a little different; John was on his back on the floor with Sue on top of him in a sixty-nine. Sue's moans were muffled by John's cock in her mouth and he was moaning into her cunt as he ate her out. Well, now I knew that I loved being a slut, fucking someone else while John watched, and I loved watching my husband, John, sucking (or fucking) another slut. Your father encouraged me to become a slut, not that I took much to get me started, and I love him for it, and I think that he loves me even more than before. We have been having parties, like the one that you stumbled into last night, ever since. Brian and Sue are regulars and over the years we have added a few other good friends to our party circle. Your grandpas know about them and come whenever they can find an excuse to slip out of home for a bit. I hope that you enjoyed your adventure with Mary and the others last night, and if you did we will include you in our parties in future. There's just one condition though. You see, not everyone approves of the way we party, so you must never tell anyone else about them, especially not either of your two grandmas, your school mates, teachers or anyone else for that matter. From the look of ecstasy on his face I understood that he wanted to join in our little orgies in future. “I promise, mummy, that I will never tell anyone who doesn't already know.”
