His Mom, Emily didn't know what to get him for his birthday and finally decided to get him a bike for his birthday. She tells her husband Jim, that she was getting him a bike for his birthday but she thought that she would also get him a joke gift also and give it to him first. She says, "I'll have to think about what to get for a couple of days." Her husband, Jim says, "Shit as old as he's getting you should probably get him a box of condoms." She says, "That's maybe a good idea, Yes I like that idea. Maybe he'd even want to use some of them on me, I wouldn't mind that at all." He says, "I know that your kidding but you never know he might just like to use them on you." She says, 'Actually I wouldn't mind it if he was too. That is if you wouldn't mind him fucking me. He says. "I'll tell you what he can fuck you as much as you want him to and Billy can also as long as you let me fuck Angie and Louise." She says, "You mean that you'd fuck your daughters?" He says, "What's wrong with that, your willing to let our sons fuck you. She tells him that he's right and it wouldn't be that much difference for one to fuck the kids than the other. Bruce hears what they are talking about and tells his brother A.J. and his sisters about what they are talking about and that they are talking about having sex with them all. Ruth says, "WOW! That would really be nice to be able to have Dad fuck me. Do you think that we should tell them about us fucking together or keep it from them. Bruce says, "I think we should keep it from them, at least for awhile anyway until we get to doing it with them. " A week later, is his birthday and when he comes down to breakfast on his plate is a box of condoms and Happy Birthday on it. He sees it and says, "WOW! great. Just what I wanted. I wonder if they'll fit me, and he pulls his pants down and his shorts and opens a package. and begins to roll one down his cock. He says, You got just the right size for me how did you know how big my cock was, Have you been spying on me to see how big my cock was." She says, "And just what the fuck do you think your doing showing everybody here your cock and me also." He says, "Shit Mom I figured that it would be alright since you got me such a personal item to use. I thought maybe you'd let me use them on you to see if they work or not." She says, "Are you saying that you'd like to fuck me?" He says "Of course I would Mom all boys want to fuck their Mom's and I'm the same way. I want to fuck you and have dreamt about dong it to you for a couple of years now." Please Mom Let me use some of the condoms after all you did give to me for my birthday." She says, "Well first of all it was joke gift for you, What your really getting is a new bicycle." He says, " You can take the bike back Mom, I'd much rather use the condoms on you if you'd let me, That would be good enough of a birthday present." She says, "Shit, I think that you really do mean it and you do want to fuck me." He tells her that he does mean it and wants to fuck her. She says, "Tell you what . You have one of the condoms on your cock right now and I don't like sucking condoms, If you take off the condom and save it for later, I'll suck your cock for you and maybe suck you off. The rest of you kids go to your rooms. They all begin to complain that they want to watch her suck his cock. Bruce tells her to go ahead and let them watch her suck him off. It would give them instruction on how to suck a cock when they do it to him, or maybe even Dad. He tells her that since they are going to be doing it together that they will probably be doing it all the time together and that Dad will be fucking the girls and that he would be fucking his sisters also since they will be fucking together. She says, " What the fuck are you planning anyway, for us all to fuck together all the time ." He says, 'Yeah Mom, I heard you and Dad talking last week about getting me the condoms and that you wouldn't mind me fucking you or Billy either and Dad would like to fuck Angie and Louise and I told them about it and they want it to happen and have Dad fuck them." She says, "OK I guess it's settled we'll all be fucking together from now on. Your sure you all want to do this with your father and me. They all tell her that they do. Bruce unrolls the rubber off his cock and his Mom then begins sucking his cock with the rest of the kids watching her. After he has cum in her mouth and she swallows his load she then has Bill to get naked and she sucks him off also and then begins eating both girls pussies. After they are finished Bruce asks her if they can play around together for the rest of the day and not get in trouble. She tells him absolutely not that she didn't want anyone to be fucking the girls until their father got home and fucked them first then they can fuck the girls. Bruce says, "Mom I hate to have to tell you this but Dad fucking them wouldn't be the first time that they've been fucked. Me and Billy have been fucking them now for about six months and fucked them maybe 20-30 times so their not virgins anymore. She tells him OK that they can go ahead and fuck together if they want in that case. The kids all fuck and suck for the rest of the day with an occasional stop for their Mom who wanted some fucking also and Bruce and Bill both fucked her that day. About 5:30, Jim arrive home from work and sees the kids all naked together and the boys having their cock sucked. Emily rushes up to him and tells him what has happened today and that she wanted them to wait so that he could be the first one to fuck the girls but Bruce told her that he and Billy had been fucking them for six months. Jim says, 'Oh they have been have they." Emily says. "Forget it Honey, It's past history now. They did it and the girls haven't gotten pregnant from them fucking them. and from now on we'll all be fucking them and they'll be fucking us. so just forget it." He tells her that she's right what has happened has happened and nothing can be done about it now. He shouts to the girls, How about me fucking you girls, who wants to be the first one to have me do it to them." Angie says,"That she wants to be first." He chooses her and takes off his clothes and starts sucking on her titties and then eats her pussy and finally fucks her. While he is fucking Angie the doorbell rings and Emily looks out to see who it is and it's her Mom and Dad. She rushes back to the living room and tells everyone to get dressed that Mom and Dad is here. They all scramble to get dressed and Emily goes back to the door and opens it. and acts surprised to see them . Her mother says, "Yeah, I bet you are I heard you say , Augh shit and go running back to the living room I guess to warn everybody that we were here. Hmmmmm, The way it looks everybody must have just thrown their clothes on as sloppy as everyone looks. Well, Well, and what do we have here, a box of rubbers. What were you all doing using up the rubbers of each other." Emily says, "Mom, how can you say such a thing, your thinking that we've been fucking in here. don't you." She says, "Yes I do think that. and if you were it doesn't matter to me and your father and if you have we'd like to join you in doing it with them. Emily honey, we would have liked to have have had sex with you and your brothers when you were little but were afraid to do it with you and them." Emily says, "Alright Mom you got us, Yeah we were fucking with the kids. Actually it started out as a joke. Jim and I were talking last week and we bought Bruce a bike for his birthday and I said that I was thinking about getting a joke gift also and would have to think about what to get and Jim said as old as he's getting, get him a box of condoms. So I decided to do it and got the condoms and made a comment about maybe he could use them on me, that I wouldn't mind him fucking me at all. Jim said that if I wanted him to fuck me then he should be able to fuck Angie and Louise . I told him they probably would like that. Well we didn't know it then and I found out today that Bruce was close and heard us talking and told the others and also I found out today that him and Billy have been fucking the girls for six months. So this morning I put the box on his plate and had a card on it that said Happy Birthday. While I was cooking breakfast he slips out of his pants and unrolls one of them onto his cock and says that they fit him. I turned around and saw him naked wearing the condom and was shocked and we had a conversation about him being naked in front of me and finally I decided to suck his cock but not with the condom on and he took it off and I sucked him off and swallowed his cum. I asked them if they wanted to do this just today or all the time and they all wanted to do it all the time together with Jim and me. So that's how we got started doing it So you don't really mind that we're doing it, Huh Mom?" She says, "Your father and I would love to join you in doing it with the kids if you didn't mind and they didn't mind. Emily tells her that they'd love to have them join them that she had wanted Dad to fuck her when she was a little girl and then the boys also wanted to fuck her. She says "Just how do yo know that they wanted to fuck me, were you and them doing it together?" Emily tells her that they were having sex together whenever they could and her and Dad wasn't around. C'mon Mom and Dad get your clothes off and let me see how big Dad's cock is and also have me suck him off. They get undressed and Emily begins sucking her father's cock. Jim begins to fucking her Mom. After they are through Emily asks why they are here. She says, "For Bruce's birthday of course we had to bring over his present. But the way it looks we're the ones that's getting the best presents. They continue for the rest of the evening to fuck with the kids and from then on they were steady visitors and continued to fuck with them all.
