Jason Winthrop and his 13 year old daughter, Janet were coming home from downtown in a crowded bus They had to stand in the aisle. All of a sudden bus hit a pot hole in the pavement and they all went reaching to grab something to hold onto. Jason reached out and felt something nice and soft and began to rub it and then looked and saw it was his daughter sweater and he had been rubbing her tits. He thought to himself, "Augh Shit, What have I done. Rubbing my daughters tits, though I must say that they sure did feel nice. I wouldn't mind rubbing them again. if I got the chance." He whispers to Janet and says, "I'm sorry Honey. I didn't mean doing that to you." Janet whispers back to him, "That's alright Daddy, I didn't mind it at all. In fact I liked it and wouldn't mind if you was to do it again to me, maybe at home." He gasps and says, "WHAT! What did you say. " She tells him that she'll tell him when they get home. When they get home he asks her what she had said and she tells him that she wouldn't mind if he was to rub her chest again, like he did on the bus, that she liked it when he rubbed her and massaged her tits. He says, "You had better watch your language young lady and don't go saying tits." She says, " Why Dad, Don't you like me to say tits?" He says, "That isn't it I don't mind you saying that word or any of the other words, but you have got to make sure you don't go saying them in front of your mother or strangers." She says, "Shit Dad, I know better than that, I figured that it would be alright with you and that's why I said it to you. Dad, would you like to massage my tits again, only much better this time. If you'd like to, I'd like it if you sucked my tits with your mouth. Would you do that for me please?" While she is talking to him she is rubbing the front of his pants and he can feel his cock getting hard. He says, "Janet, You need to stop that." She says, " Don't tell me that your about ready to cum already?" He says, 'No, I'm not ready to cum but if you kept that up it wouldn't be long before I did. She says, "Dad, Why don't you and I both get naked and you can suck on my tits and I can suck on your cock and you can also maybe eat my pussy." He says, "Janet what has gotten into you. To want to do these things and to have me suck your tits and you suck my cock. It wouldn't be right. I'm your father. She says, "Shit Dad, What the fuck difference does that make. Your a man and I'm a girl and your supposed to fuck girls and I want you to fuck me." He says, "Oh My God, Now you want me to fuck you. This is getting worse. You do know that if I was to fuck you that I could possibly make a baby in you." She says, "Yeah dad, I know and I would love if you did and have your baby. But Josh has been fucking me for about a year now and I haven't gotten knocked up yet." He says, "Josh has been fucking you for a year. How about your sister, Has he been fucking her also?" She says, Sure, we have a schedule. One day he fucks me , then the next day he fucks Sue and the next day he fucks me again, So you see you can join us and you'll be able to fuck me and Sue also and have Josh to suck your cock for you also. I'd love it if we could get mom to join in with all us and we all fuck together. Josh has said that he would love to fuck Mom. Do you think that you could talk to Mom and see if she'd like to go along with all us fucking together. Josh has a nice big cock on him and Mom would probably love to have him fuck her." He says, "I could maybe feel her out and see how she feels about it but I wouldn't count on her wanting to do it. I've been thinking, since you have been fucked by Josh for the past year, maybe it wouldn't be too bad if I was to maybe suck your tits and eat your pussy and maybe fuck you , if you really want me too." She says, "I do Dad, I Do. Let's get our clothes off and get started, I'm anxious to suck your cock and see how your cum tastes . At least we have a couple of days to fuck together before Mom gets back With Josh and Sue. In case she won't go along with us fucking together. It might be a while before we can fuck together again. I'll tell Josh and Sue that we can all fuck together whenever your around and Mom has left the house. He begins to suck her tits and eats her pussy and she tells him that she wants to suck his cock and make him cum. She then begins sucking his cock and a few minutes late he cums in her mouth and she swallows his load. She tells him that when he is ready to go again, then he can fuck her. During the time he is waiting to recharge his nuts. He sucks on her tits and eats her pussy some more. After about an hour and a half he then fucks his daughter. They continue to have sex together the rest of the evening and Janet sleeps with her father. The next day they start all over again. Then the doorbell buzzes about 11:00 and he hurries to put on his pants and a shirt. He goes to the door and opens it and it is his sister, Marge and her husband, Bill. He tells them that he is kind of busy right now and to maybe come back later. Marge forces her way in she says, "Shit Jason the way you look, it looks like you just through your pants on and you didn't even zip up the zipper and your one eyed horse is trying to get out of the barn , Can I see your one eyed horse? I've been wanting to see it since we were kids together, but never got the chance . Of course now it will look much better and bigger. She reaches out and sticks her hand into his pants and pulls his cock out of his pants. She says, "Oh Yeah it's a beauty. Mind if I suck it? Before he can answer she has it in her mouth and is sucking it. He says, "Shit, Is this alright with you what she is doing?" Bill says, "When she wants something she usually gets it, and I don't really mind her sucking your cock. With the way it looks I wouldn't mind sucking it myself. Just then Janet comes out from the living room and is still naked. "Dad, What's Taking so long, Who was it, OH! Aunt Marge and Uncle Bill, Your here. SHIT!. Marge says, "Hello Honey, Your looking very nice today in your birthday suit, Don't she Bill. I'll bet that your probably getting a hard on seeing her like this." He says, "If I didn't have a hard on from you sucking Jason's cock I sure would get one seeing Janet naked. She has a great body on her for her age. I wouldn't mind getting some of her myself." Jane says, "Well shit get your clothes off Uncle Bill and you can have some of me and I hope I can have some of your cock also." He says, "Honey you can have my cock and can have me do to you whatever you want me to do to you with it. That is if your father doesn't mind." She says, "Shit He won't mind, He's been fucking me ever since yesterday afternoon and I love it, so I guess that it's OK if you fuck me also, right Dad?" Jason says, "Shit, Why Not." Marge says, "Why don't we all get our clothes off and you can see my body and how big my tits are now, I would imagine that you'd like to see my tits." He says "I wouldn't mind, and I wouldn't mind fucking you also if you'd be willing." She tells him that she is more than willing and would love to be fucked by him all the time from now on. He says, "Well that would have to be up to Mary. Since you know about Janet and I fucking together, I might as well tell you. I was going to feel Mary out and see if she would be interested in maybe having us all to fuck together all the time. Marge says, "If she was to go along with that do you think Bil and I could join you in the fucking together. Beside Bill wouldn't mind fucking Mary either. maybe Janet could come over to our house and help to get our kids into wanting to fuck with Bill and I." Janet says, "Shit, I'll bet that they fuck already and are either fucking among themselves or their fucking their boy or girl friends. Marge says, "How about I come over and I'll talk to Mary and sort of see how she feels about maybe doing something like this with the kids and if we can get her to go along with doing it then we can all have good times together . Shit we could maybe even make a wad of cash out of doing this. We could maybe make some movies of us fucking the kids. All we'd have to have is a few masks to cover our faces so nobody can see what we look like. Yeah, I like that idea. Oh well lets get some action going here and stop all this talking. Come on brother dear, stick that cock of yours into me and fuck me and I'm sure that Janet is ready to have Bill to fuck her as well. Jason fucks his sister Marge and Uncle Bill fucks Janet. After they are finished they all get dressed and go over to Marge's house and her kids are happy to see Janet. The kids all go up to Agnes and Beverly's room and they tell their brother that he can come into their room also. When Janet gets in the room she asks them if they know about sex and Beverly. Beverly says, " Shit, Of course we do. We're about as old as you. Janet then says, "Have you ever fucked your sisters Ted?" He sort of hems and haws and Bev bursts in and says, "That wouldn't be right for him to do that to us. Though I wouldn't mind having him do it to me ." Janet says, "I was just wondering if maybe Ted would like to fuck me. I've wanted to be fucked by him for so long." Ted says, "Holy shit you want me to fuck you, You really mean it. I would love to fuck you if you do mean it." Janet says, "I mean it. Why don't you get your clothes off and let me see your cock. He gets undressed and is soon naked . Janet takes his cock and puts it in her mouth and begins sucking it. Janet says, "OK, now in order to fuck me you have to tells me the truth, Ted. Have you ever fucked your sisters or have they ever sucked your cock?" He says, "OK, They have sucked my cock, I've wanted to fuck them but they wouldn't let me. They were afraid of getting pregnant. Your not afraid of getting pregnant if you let me fuck you?" She tells him No. She tells him that is good that his sisters have sucked his cock and that he can now fuck her. He sticks his cock into her and begins fucking her. When he has cum in her she cleans up the cum that is dripping from her cunt and says, "Let's go on downstairs now and you'll get a surprise when we get down there. He puts his clothes on and she starts out the door and is still naked. He says, "Holy shit, Your going out like that, Mom and Dad and your father will see you naked. She tells him that it will be alright. To come on and lets get downstairs. They go downstairs and when they get there Jason is fucking Marge and Bill is watching them . They are all naked. Janet rushes over to Bill and begins sucking his cock. Bill says, "Does any of the rest of you like to get into the act also. Just come on over and take over from Janet and Ted you can take over from your Uncle Jason and go ahead and begin fucking your mother. Ted does go and takes over fucking his mother and Beverly takes over from Janet and begins sucking her father's cock. Bill tells Beverly that she had better stop sucking him or he'd be cumming and have to wait before he could fuck her. She stops and Bill begins to then fuck her. After Ted and Beverly were finished fucking they wanted to know what happened and why they had started to let them do this . Beverly says, "WE would have loved to do this with you a long time ago if you'd have let us. They tell them what had happened between Janet and Jason. and that if they would like they can join in with them all fucking together and they'd be able to fuck Janet and her sister and brother and also their Aunt Mary. They all shout YES! that they want to do it. Marge says, "Now all we have to do is get Mary to go along with this. For the next two days they all had fun together and finally it was time for Mary to return with the rest of the kids. Jason meets Mary and they come home and when they get there Mary sees Marge and Bill and wants to know why they are there. Marge tells her that they need to talk and go to Mary's room. The kids all go to their room and Janet tells them what has happened and about their Dad having fucked her and her being fucked by Uncle Bill. Josh says, "Holy shit, You mean that Dad and Uncle Bill have both fucked you. Shit that means that I can fuck you now since they have done it to you. Janet tells him that it's OK with her if he was to fuck her now and that Dad won't mind him fucking Sue also. That he was going to be fucking her also. Marge is working on Mom right now to get her to go along with fucking with us and then you can fuck Mom. He says, "WOW! That would be great if I could fuck Mom. Meanwhile over in Mary's room, Marge begins to talking to Mary. "Mary, I hope what I'm about to tell you doesn't hit you too hard. You wanted to know why we are here. Well I don't really know the best way to tell you this without hurting you too much. We've been over here almost all the time for the last two day. You see Jason has been fucking me. He's fucked me so many times I've lost count of how many he's done it to me. Mary says, "HE'S WHAT! HE'S BEEN FUCKING YOU." Just then there come a knock on the door and Jason comes in, He says, "I guess you told her, Huh? Marge. I heard the screaming downstairs. Mary, Honey what she has told you is true. I have been fucking Marge for the last two days. The reason we decided to tell you about it is we decided to tell you about it and try to get you to go along with doing it also." Mary says, "What do you mean to go along with it? You mean to sort of wife swap. You fuck Marge and Bill would fuck me?" He says, "Well, actually yes that's part of it. Actually You would be able to be fucked by Bill and Ted and Josh." Mary says, "What, Ted and Josh , But their just children." Marge says, Ted maybe a child but he has a man sized cock on him and I'll bet that Josh does also. Mary says, "I didn't know that you fucked with you kids Marge." Marge says, "Well actually we haven't until a couple of days ago. After Jason fucked me, We all got to talking and decided to try to get you to go along with us and also get the kids involved, and Janet said that she thought that my kids were already fucking together and as it turned out they were. But she went to my house to sort of feel them out and found out that they had been fucking together." Mary says, "How the fuck did Janet get involved in all this anyway?" Jason says, "I hope that this doesn't affect you too much honey, But I was fucking Janet when Marge and Bill first came over, and I through on pants and a shirt and forgot to zip my pants and the head of my cock was sticking out and Marge saw it and began sucking it. That is how it all began. I know you want to know how I got started to fucking Janet. Well we were riding home on a bus and it hit a pothole in the pavement and I lost my balance and went grabbing for something and I grabbed Janet's sweater and began feeling it. Later I told her I was sorry about feeling her chest and she told me that she didn't mind and would like me to feel her a lot more times and maybe even suck on her titties. Well we talked and things led to me ending up fucking her and she told me that her and Sue had been fucking with Josh for about a year." Mary says, "OH! My God, You mean that you actually fucked your own daughter. and that she has been fucking for about a year with Josh.?" He says, "Well I hope you aren't too upset about it, but we would like to have you be included with us." Janet says. "Bill would love to fuck you and Josh has said that he would love to fuck you also Mom and as for how big his cock is, Would you mind if he showed you what it looks like. Maybe you'll like what he has in his pants and get you to want to join us." Maybe if you'd like Ted could show you what he has also, actually his cock is way bigger than Josh's cock." Mary says, "Well if they didn't mind letting me see their cocks, I wouldn't mind seeing them. They both take their pants off and bare their cocks to her. Mary says, 'Shit Ted's cock is about the same size as Jason's cock. "She then asks Josh if he'd mind if she was to suck it and he tells her to go ahead and she does. Marge says, "Does this mean that your in with us and don't mind fucking with the kids?" Mary says, " Marge, You were right, these two do have man sized cocks on them and I guess I'm into it myself now that I've sucked my son's cock" Marge says, "Shit lets all get naked and choose partners. They do and keep changing partners the rest of the evening. and from then on they visited each other much more than they used to.
