Note: This story was dynamically reformatted for online reading convenience. Mary Francis and her brother Tom were having sex together for about the last year and her brother kept wanting her to let him fuck her, but she wouldn't let him go that far and fuck her. She'd only suck him off and let him suck on her titties and eat her pussy and that was as far as she would go. Finally one day she tells Tom, " Tom, I've decided that I want to fuck Daddy and I'll bet that you would like to fuck Mom, right." Tom says, "Shit, yeah, I'd love to get hold of Mom and fuck her and I wouldn't mind sucking on Dad's cock either, and have him cum in my mouth." She says, "What do you think the chances of your fucking Mom and sucking Dad's cock are and having Dad to fuck me." He says, "Shit, are you kidding, I'd say the chances are absolutely zero. It'd never happen. Maybe Dad would fuck you but Mom would never let me fuck her. " She says, "Tell you what, I'll bet you that I can get Dad to fuck me in the next couple of days and maybe even have Mom to let you fuck her." He says, "Shit, how the fuck do you expect to do that. It'd be nice if you could but it'll never happen." She says, "I'll bet that I can do it and if I don't get it done, then I'll let you fuck me as a consolation prize." He says, "You mean that if you don't get Dad to fuck you, then I can fuck you instead." She says, " That's right and just think, if I fail you'll get to fuck me and if I succeed then you'll most likely be able to fuck me all the time anyway because the whole family will be fucking together. " He says, "Shit the whole family. You mean that we'd be fucking Agnes and Clint also. What do you want from me if you do succeed in doing it." She says, "If I do succeed in doing it I'll want you to eat my pussy for 15 minutes a day continuously for 7 days." He says, "Shit, that ain't a bad deal, I'd love to eat your pussy for 15 minutes every day for even longer than 7 days." That night, Mary's father is in the living room in front of the TV but he is reading the newspaper and has it up in front of him.Mary comes strolling in and doesn't have a stitch of clothes on. She goes over to her father's chair and says, "Dad, Can I ask you to do something for me?" He says, "Sure honey what do you want me to do for you?" He goes back to concentrating on the paper and she says, "Dad, I want you to fuck me." He says, 'sure honey, I'd love to when do you want me to do it to........what!" He puts the paper down and sees her naked and gasps and says, "Holy shit, what the fuck are you doing here in front of me naked?" She says, "I told you Daddy, I want to suck your cock and I want you to fuck me, right now before Mom gets home." He says, "Well I must say that you sure do look tempting there in your birthday suit. " She says, "Yeah Dad,I can see that you like what you see also, your starting to get a tent in your pants from your cock getting hard and sticking out." He says, "Alright young lady, that's enough of this kind of talk, if you don't go get some clothes on right now I'm going to give you a spanking and you won't be sitting down for a week." She says, "Well if you got to spank me go ahead but I'm not putting on any clothes until you fuck me. Please Daddy fuck me. It wouldn't be the first time I've been fucked, I've been fucked lots of times by Tom and Clint, but I want you to fuck me." He tells her to get over here and get across his lap and she does but as she does she spreads her legs and he gets a closeup view of her pussy lips. He gives her a light pat on her ass and then spreads her legs even further apart and looks between them . He says, "Shit, how the fuck am I going to resist and pass this up. Get up from there and lay down on your back on the couch and spread your legs as far as possible. Your certain that you want me to do this to you. Is it alright if I eat your pussy first and then fuck you honey? She tells him that she would love it.. He gets down between her legs and begins eating her pussy and while he is doing it in walks Tom. He says, "Holy shit, You did it, you got Dad eating your pussy." She says, "Yeah, and he's going to fuck me when he's finished eating me." Hugh says, "Well your here to watch the going on's also, huh?" It won't be any different from when you fucked her." Tom gets a puzzled look on his face and says Huh? Hugh stops eating her pussy and lines his cock up with her pussy hole and plunges in and she lets out a loud scream. He asks if she's alright and she tells him that she's fine it's just that she's not a virgin anymore thanks to him. He says, "Holy shit, You mean that you have never been fucked before now and she tells him that she hasn't that she lied about Tom and Clint having fucked her. She says, "I only let them eat my pussy and I'd suck their cocks but I'd never let them fuck me. I wanted you to take my cherry from me. He says, "Well it looks like you succeeded in getting me to take it from you. Though really I didn't mind taking that from you." He is about ready to shoot his load of cum and moves up to her mouth and sticks his cock in her mouth and unload into there and she swallows it all, blood and all.She says, "Dad, Tom would also like to suck your cock for you and would like to fuck Mom. Do you think that it would be possible to do them two things?" He says, "Well I know that if he wants to suck my cock that he can do that and if he wants to have me suck his cock I'd love to do that to him also. But now having him fuck your mother is a different story and may be a little more difficult. You do know that now that I've fucked you and if I let him suck my cock and I suck his cock that we will have committed incest and that's against the the law if we're caught. So make sure that neither one of you tell anyone about we did here tonight or what we will be doing together later and with your mother if I can persuade her to go along with us doing it. What about Clint and Helen, do they know what you two have done or are about to do here. She says, "No, Dad, they don't know anything about it, YET. We'll have to break it to them and see if they want to go along, though I'm certain that they'll love the idea of being able to have you fuck Helen and suck Clint's cock. Clint does eat my pussy and I suck his cock for him and Helen hasn't sucked them off but her and I have ate each others pussies. Hugh says, "Well you both had better get upstairs and get dressed, especially you young lady. Tom says, "I thought you were going to suck me off, Dad?" He tells him that he has already shot his wad into his sisters mouth and we'll have to do the sucking later, since he wouldn't get anything out of him. They both leave and he goes back to reading his paper and stops reading and begins to thinking how he's going to tell his wife Helen about what has happened her tonight. Later that night after his wife Helen gets home he says to her, "Honey, I think that you may hate me for what I'm about to tell you and then again, You may love it and love the idea I propose to you." She says, Alright, what the fuck did you do now that's going to cost us more money." He says, "I didn't do a thing that's going to cost us money. Maybe we could even make some money with it. Anyway what happened was this. I was reading my paper and I hear Mary say, "Dad, Can I ask you to do something for me?" He says, "Sure honey what do you want me to do for you?" Then she says, "Dad, I want you to fuck me." I said ," Sure honey anytime." Then it downed on me what she had said and I put my paper down and there she stood, completely naked in front of me. I must say, she was sight to behold and I started to get a hard on right then looking at her. She has a fantastic body on her for her age. Well I told her to go get some clothes on and she said that she would after I fuck her." Helen says, "Holy shit, that's what she actually did come down and let you see her in the nude. Wait'll I get hold of that young lady, I'm going to skin her alive." He says, "Hold on, I'm not finished yet and you may want to skin me alive also. After she said that I asked her what brought this on and she said that she wanted me to fuck her. That she knew all about fucking and that Tom and Clint had fucked her lots of times and she'd sucked their cocks also and now she wanted to suck my cock and wanted me to fuck her." Helen says, "I think I know where this is leading to. You didn't actually fuck her did you?" He says, "Actually Yes I did and it was great. But let me continue. I said , "You mean that your brothers have been fucking you and she said yes. So then I said Get over here and I'm going to give you a spanking and your not going to sit down for a week, So she came over and laid across my lap and as she did she spread her legs and I could see down into her pussy and saw her pussy lips and I couldn't resist, I had to see more of her pussy. I had her lay back on the sofa and spread her legs and I got down and began eating her pussy and while I was Tom comes in and sees us and tells her that it looks like she won the bet. Anyway I ate her pussy and then I fucked her. After we were done she said, "I knew you were going to fuck me, Daddy I could feel the size of your cock when I was laying across your lap and feel your hard on. Anyway when I fucked her I stuck my cock into her and pushed nice and hard and she let out a scream and said to keep going. She had lied to me about being fucked by Tom and Clint and she had never been fucked before. Well I asked her abut what Tom had asked about a bet and she told me that she bet him that she could get me to fuck her and also that Tom wanted to fuck Mom and suck Dad's cock also." Helen says, "Shit that's fantastic, So you fucked your daughter and my son wants to fuck me. Course as old as he is he should have a nice sized cock on him. Hmmmmm! I wonder just how big his cock is anyway?" Hugh says, "There's one way to find out, have him come down here and get his clothes off and see how big it is." She says, "And you wouldn't object if I was to do that." He tells her that why should he object after all he fucked their daughter. She says, "Alright I'll do it, You do know that if I do this and with you having fucked Mary that we'll all be committing incest with our kids." He says, "Does that bother you, I know it don't bother me any." She tells him that it won't bother her either. She goes and calls all the kids down and they come down and she says, Tom and Mary, so you both want to do this?" They both say that they would. She says, "Clint, Agnes, Have you heard about what happened here earlier this evening." Agnes says, "You mean about Mary having Dad fuck her. Yeah we heard about it and wish we had seen him do it to her." Helen says, "Alright, now how do you feel about it if we were all to fuck together?" Agnes says, "You mean that Daddy would fuck me and I could suck his cock?" Helen says, "Exactly, Would you like to do that with your father?" She tells her mother that she would and that Clint would also like to fuck her also. Helen says, "Alright let's all get our clothes off and you all can see each others bodies and your father's and mine. They all begin to get undressed and are soon all naked. She says to Hugh, "Shit Tom's cock is about the same size as yours or maybe even a little larger than yours. Shit, I'm going to love being fucked by that thing of his. Actually Clint isn't that bad looking either for his size and it'll only get bigger and bigger. Come here honey and let me suck that piece of meat of yours a little bit before you stick it into me and fuck me. Clint you can fuck Agnes if you'd like to or maybe even Mary." Hugh says, "Clint, You fuck Mary, I've already fucked her and I haven't fucked Agnes yet. I'll fuck her while you fuck Mary. They all fuck their partners and when they were through. Tom says, " That was great, Mom, can I do it to you from now on or was this just a one time thing?" She tells him that he can fuck her and his sisters from now on as much as he wants as long as they are agreeable and want to be fucked by him or Clint. Mary says, "Does that go for Dad also, that he can fuck Agnes and me whenever he wants to or we want him too." Helen says, "Yes, he can fuck you whenever he wants to, but you do know that men aren't like us girls. They can't fuck one time after another like us girls can. They have to rest for an hour or more after they fuck and cum in order to resupply their balls with more cum. Tom says, "Mom, Dad, do you think it would be alright if I was to have my girlfriend over here and be able to fuck her?" Helen says, "I don't think that is too good an idea. We have to make sure that nobody ever finds out about what we're doing here together." Tom says, But Mom, She has sucked me off about 4-5 times and she wants me to fuck her and her parents are always home or at least one of them are and we can't get any time together long enough to get to fuck. She says, "Well maybe we can let her come over and you can go to your room 'To Steady' or "Do your home work' and we can all not have any sex together while she is here and that way she won't find out about us fucking together. Tom says, "Can I have her to come over tomorrow after school. " Helen tells him that she can come over tomorrow. He goes and calls Terry, his girlfriend and tells her that they can do their homework together tomorrow after school and to ask her Mom if it's alright. A few minutes later she come back on the phone and tells him that her mother says that it's OK as long as his Mom is at home. Helen tells her on the phone to get her Mom and then tells her that she will be home all day tomorrow and not to worry. The next day Tom and Terry come home and go to his room. They both get undressed and he sucks on her tits and then eats her pussy and begins to fuck her and the door opens and it's Clint. Clint says, "I see your getting to fuck her." Tom shouts at him and gets up off Terry and begins chasing Clint out of the room, just as Helen is coming upstairs to see what the shouting is about. Tom says, "Mom, He came in just as I started fucking Terry." Terry comes out into the hall and she doesn't have any clothes on either, and says, "Tom, You mean that your Mom doesn't mind you standing there naked in front of her." He says, "Oh, Shit, Mom, What the fuck are we going to do now. I'm sorry, I completely forgot I was naked when I started chasing Clint." She says, " It's not your fault honey it was all Clint's fault for coming in on you when you were fucking Terry. I think we should come out into the open with her and see what she thinks about it. Terry honey, I don't really mind seeing him naked like this, the same as I don't mind seeing you naked either. You see we have sex together and it's nothing to see each other naked." Terry says, "Holy shit, You mean that Tom fucks you and his sisters also, and his Dad fucks his sisters also?" Helen says, "Does that shock you honey?" Terry says, "Shit no, I wish that Mom and Dad would do that with us. I know my brother would love to fuck Mom and I'd love to have Dad fuck me. So your not mad that Tom has been fucking me." Helen says, "No, That's why your here, Tom said that you had sucked his cock about 4-5 times and that you wanted him to fuck you but couldn't find a place to fuck at. So he asked if he could have you over here and I told him yes that we wouldn't do any fucking while you were here so that you didn't find out about us fucking together." Terry says, "Shit, you don't have to worry about me telling anyone, I'll keep it quiet and won't say a word to anyone about you all fucking together. Do you think I could come back sometime and meet your husband and maybe if he wanted to he could fuck me also. I'd love that, to have an actual man to fuck me. I've dreamt about Daddy fucking me but figured that it would never happen. Helen says, "You can come over whenever you want to Honey and my husband would love to fuck you also as would Tom's brother, Clint, even though he's only 10 years old he sill has a nice sized cock on him that could take very good care of you. Have you ever been fucked before? I didn't hear a scream from you when Tom began fucking you. " She says, "Yes Mam I have been fucked before about 4-5 times by my brothers whenever Mom and Dad wasn't at home." Helen says, "Oh! So your brother fucks you. Has anyone else fucked you beside him?" She says, Well actually when I said I'd been fucked 4-5 time I really meant 4-5 time by each of my brothers. I have 3 brothers and each of them has fucked me about 4-5 times each. When Mom and Dad went out the first time my brother Roger and I fucked together and my other 2 brothers came in and caught us and they wanted to fuck me also and I let them and after that when Roger fucked me they did too. I enjoyed it, being fucked three times, one after the other. maybe Tom , Clint and your husband can fuck me one after the other also sometime. Do you think that it would be alright if I had my brothers to come over sometime and maybe let them fuck Mary and Agnes?" Helen says, "Well, since they've been fucking you, I guess that they can keep their mouths shut about what happens here, so if you want to bring them over sometime, OK go ahead and bring them over, in fact maybe they could fuck me also if they'd like to." Terry says, "I'm sure that they would because they all would like to be able to fuck Mom sometime. Terry leaves and tells them that she'll try to get it where her brothers can come over also. They next day she comes back and has her three brothers with her. They go in and Helen tells her and Tom to go ahead to his room and the boys can take care of her. Roger says, "Holy shit, You mean that what Terry told us is true, that your going to let us fuck you, Mrs. Francis? Helen says, "It is if you really would like to fuck me, I'm not going to make you do it to me unless you really want to fuck me." He says, Shit I do, we all do." She says, "Well then let's all of us get our clothes off and see what we all have to play with, for your size, Roger, you should have a pretty nice sized cock on you for me to play with. I like my cocks nice and big. They all get undressed and Helen says, "Well you do have a nice one on you and your brother also has a nice sized one on him also. I was wondering has any of you ever fucked a girl or your brother in the asshole before. Graham says that he has fucked Roger in the ass a few times. She says, "How about Roger fucking me in my pussy and Graham you fuck me in my asshole and Matt I'll suck your cock and suck you off and all three of you can fuck me at the same time." They all like the idea and they do it to her. She says, "I hear that you guys would like to fuck your mother and Terry would like to have her father fuck her." They tell her that it's true that they would. She says, "Well maybe I can help you guys out and get her to do it with you. Why don't you come back again tomorrow and the next day and the next. Your mother will be wondering why you keep wanting to come back over here all the time. When she asks why you keep coming over here tell her to come over and talk to me. Two days later Grace Winters calls and says that she would like to talk to Helen. Helen tells her to come on over and they can talk. About 15 minutes later Grace come over and they sit and talk. Grace says, "I was just wondering what is going on over here that Terry and her brothers keep wanting to come over here all the time." Helen says, "Nothing is going on, they just play games together. Grace says, "What kind of games?" Helen says, "Oh! Post Office and strip poker, they like that game the best." Grace says, "STRIP POKER! You let them play strip poker, boy you are liberal. You actually let them get naked together" Helen says, "I was just kidding you, They don't play Post Office or strip poker." Grace says, "OH! that's a relief to hear. Can I trust you, Helen. When I heard you say strip poker what flashed through my mind was maybe I could get to see the boys naked. I would love to see what the cock on Roger looks like, I would think that he has a monster on. Me and Les has talked a couple of time about having sex with the kids but we never have, we were afraid that they would hate us for trying to do it with them." Helen says, "You'd be surprised , they would love to have sex with you and your husband and as for Roger he does have a monster cock on him and Graham isn't that far behind him." She hollers upstairs, "ROGER COME ON DOWN HERE" Roger comes down and he is naked. and says, "Hi Mom." She gasps when she sees him naked and asks him where is his clothes and he tells her that there upstairs in Mary's room where he had just started to fuck her, Terry is upstairs with Tom and he's fucking her. Mom I haven't cum yet and my balls are still loaded, The one that I really want to fuck the most is you, if you'd let me, I can fuck Mary later, but I really would like to fuck you though." Grace says, "You mean it, you want to fuck He says, Yes and Terry wants to have Dad to fuck her too. Please let us do this with you and Dad, Graham and Matt and June too would like to be able to fuck with you and Dad, if you'd let us. She motions for him to come over to her and she hugs him and then takes his cock into her mouth and begins sucking it. She says, This should hold you until later when I suck you off but now I want you to fuck me and cum in me and hope that you can make a baby in me, your father cant make babies anymore and I've been wanting to have another one. I hope you don't mind us doing this Helen. Helen says, "It's alright, me and Hugh fuck with our kids too. Roger fucks his Mom and when they are done they all go upstairs and go to Tom's room and go in and Terry, screams "MOM." Grace tells her it's alright to keep going until he cums in her. From then on the Francis family and the Winters family had many enjoyable days and nights together from then on.
