Mary and Her husband Frank Lewis and their 4 children were a happy and normal couple, that is until one day when Mary had to go piss and her son Larry was taking a shower at the time. She knocked on the bathroom door and told Larry that she had to pee real bad and can she come in. He tells her to come on in that he didn't mind. She says, "Now you behave yourself and no trying to peek at me while I'm on the toilet." He tells her that he won't that if he did she could peek into the shower and see him also. She tells him that she may just do that and see how much he has grown since the last time that she seen him naked. He tells her that he wouldn't mind if she saw him naked. She says, 'OH! You wouldn't mind me seeing you naked huh? I'll bet that you wouldn't mind seeing me naked either. He says, "Well I think that it would only be fair if you saw me naked that I get to see you naked also. She says, 'Just don't go holding your breath waiting for that to happen. She is sitting on the toilet and looks across the way to a mirror on the other side of the bathroom and she sees the curtain moving and open a little and she see Larry's head peeking out the curtain. She says, "I saw that young man. You get out of that shower right now and towel yourself off. He says, "Holy shit Mom you want me to get out of the shower naked like this and you can see me." She says, "Absolutely, You was looking at me and saw me pissing and my pussy and now it's time that I saw your cock. Augh, Shit Mom you can't do this to me ." She says, "You just keep thinking that now get the fuck out of the shower right now or I'll pull you out of it. He finally gets out of the shower and he has a hard on. So you have a hard on, I suppose that's from seeing me piss and seeing my pussy. He says, "Well only partly Mom. I was already starting to jack off with the stream of water focused on my balls and it was making me horny already and I started to jack off. She says, "Oh so you were jacking off and after you saw my pussy that really gave you a reason to jack off right?" He says, "Yeah Mom, I admit it I was looking so I could see your pussy. I wish I could see your titties also. She says, "Oh so you'd like to see my tits huh? I must say that you do have a nice big cock on you there. Shit the way it looks , I'd say that it looks like it's even bigger that your fathers cock. Would you mind if I was to measure it and see if it's bigger than your father's. He tells her that he wouldn't mind and she spreads her hand open as wide as she can and puts her thumb right at his piss hole and stretches her hand back and has her little finger almost at the end of his cock in his hairs. She says, Shit your cock is about an inch longer than your fathers. When I put my thumb on your father's piss hole and stretch my hand my little finger goes right into his hairs and touches his lower belly, with you I can't even reach the hairs. He says, "You could maybe cup your hand around it Mom and see how much hangs out and see if it's longer than Dad's cock . You could maybe move the skin back and forth some also. If you'd like. I wouldn't mind." She says "Oh, so you'd like me to jack you off huh? Wanting me to move your skin back and forth and then I suppose that if I was to do that long enough You'd want me to maybe put my mouth on your cock and catch the cum that come out of you." He says, " Well that sounds good to me if you'd like to do that to me I wouldn't mind at all." She grabs his cock and starts pulling him towards the door and out into the hallway. She starts to talk him to his room and stops at the girls room and knocks on the door. and tells the girls to come to Larry's room. The door opens and Janet the oldest daughter says, "Holy shit, Why is Larry naked and your holding his cock." The younger daughter Susan hears her and comes running over to the door. She says, "Holy shit he is naked." Mary says, "What do you think about the looks of you brother like this, do you like to see him like this?" They both tells her that they do like him like this but why is he naked like this Mom, He must have done something real bad. Mary tells them to come to the boy's room and she'll explain what happened. When they get to the boy's room she tells Cole to get up. Mary says, "Your brother here is very interested in seeing titties and pussies, and I'd be willing to bet that his brother Cole is the same way also. Right Cole?" Cole says, Yeah Mom I like them also. Mary says, "Good. Now the girls here seem to enjoy seeing Larry's naked cock and I'll bet that they would enjoy seeing yours also, so get your clothes off and let them see how big your cock is also. Cole says. "Mom are you serious, You want me t get naked so they can see me naked." She says, "Well, Yes but it's also for me to see you naked too. Now get your clothes off so I can see your cock and see how big it is and I'm sure the girls want to see it also." Janet says, "Yeah Mo we wouldn't mind seeing his cock also. Cole begins getting his clothes off. Mary says, "OK Good now that you girls can see Larry's and Cole's cocks,I think it's time that they get to see you girls tits and pussies also." Janet says, "Holy shit Mom, you want us to get naked also, What the fuck is going on with you. Shit the next thing will be that you'll want us to be fucked by them." May says "That is exactly right they are going to be fucking you, but not right away, They are going to be fucking me first and then they can have you two later after your father fucks you both." Janet says, "Shit are you serious Mom? Dad's going to fuck us?" Mary says, "Most likely, He don't know about it yet , but I'm sure that he will be willing to fuck you both. While your brothers fuck me." Larry says, "Holy shit Mom, Your going to let us fuck you, you are taking about having us put our cock into your pussy, right? She says, "Of course or do you know of another way to fuck a girl?" Janet says, " Shit Mom what the fuck got all this started anyway?" Mary says, "I have to piss real bad an Larry was taking a shower and I told him not to go peeking while I was on the toilet and then he did peek and watched me piss and saw my pussy and then I decided to make him pay for doing that. Don't you like seeing your brothers naked like this?" Janet says, "Shit of course we do and we like the idea of having them fuck us also as long as you don't mind. It's just having to wait until Dad fucks us first. Mary says, "You can suck their cocks if you'd like while your waiting for your father to get home, course you'll have to wait for them both to replenish their supply of cum since they are both going to be fucking me first. Mom couldn't you just have one of them to fuck you and let have the other on and then you can be fucked by him later and we can then be fucked by the other one also later." Mary says, "Oh alright I guess I could be satisfied with just one of them fucking me for now. Which one do you want to be fucked by?" Janet says, "Really we'd both like to have Larry fuck us since he's the biggest but you can have him to fuck you and we'll get him later. She thanks them and tells him to begin by sucking her tits and then eat her pussy . He follows her advice and does and then he fucks her and cums in her. While Larry is fucking their Mom the girls and his brother are all watching intently and leaning down between their legs and watching his cock as it moves in and out of their mother's cunt. He ends up cumming inside her cunt and pulls out of her and when he does, cum begins leaking out of her. She then tells Cole to come on and begins fucking her also and he does .. He also cums in his mother. When he was finished she tells them both that they were great. Janet and Susan want to know if if would be alright if they were to suck their brothers cocks. She tells them that they can suck them off all day long until she tels their father what they all have done, but they wouldn't be getting any cum out of them right now that it'll be a couple of hour's before they'll be ready to go again. She also tells them don't forget that they can suck their brothers off but NO letting them fuck them, That their father has to be the first one to fuck each of them. If they try to fuck you send them to me and they can fuck me instead. They all begins to do their normal things of the day and then finally it gets to be 5:00 and about time for their Dad to be getting home. He arrives and they all come rushing up to him and hugs him and he says, "What is with them, they have never greeted me like that before when I get home from work. Mary says, "I should have expected something like this from them . There's something that their after and want you to do. He says, "Well with a greeting like that I'll do my best to satisfy them. What is it they they want ?" Janet says, "Tell him Mom Tell him right now. Then he can do me before supper. He says, "Oh I've got to something to her." Mary says, "Let's go to our room and I'll tell you all about what happened today." Janet says, "NO Mom, tell him right here so we can see his reaction to it." Mary says, "Alright , I guess I can since you all know about it anyway and it involves you. She starts out by telling him that she had to piss real bad and Larry was taking a shower at the time. and she saw him peeking at her while she was pissing." He says, "Are you sure that they all should be hearing this about you pissing and such." She tells him that it's alright to have them hear that they already know all about what happened," She then tells hi everything that happened today. and he says, "OH My God, You actually let Larry and Cole fuck you and the girl to suck their cocks and you want me to fuck the girls. At least that is the best part of it all having me to fuck the girls. You really want me to fuck them both?" She tells him that she does. He says, "Well if I have to do it I guess I will though I'm sure going to like doing it to them. Janet says, "Do you mean it Dad what you just said, 'That your going to like fucking us." He says, "That's exactly what I said and mean. I've thought for a long time that I would love to see what it was like to fuck you and Sue but was afraid to say anything to your mother about it and I thought that she'd no want to try something like that. So your anxious to have me fuck you right, Janet?" She tells him that she is and Susan is also. He says, Well get your clothes off and I'll fuck you right now and that will give me time t recharge while we're eating supper and I should almost be ready for Susan not to long after supper. He begins taking off his clothes also and both of them are soon naked and she grabs his cock and begins sucking it for him and also sucks his balls and sucks one in her mouth and rubs her tongue all over it. He stops her and tells her that he is going to be cumming if she keeps that up. She stops and he begins sucking on her tits and then eats her pussy and finally fucks her and cums in her. They all get redressed and have supper and after supper about a half hour later he then fucks Susan . While he is fucking Susan, Janet is being fucked by Larry and after her father has fucked her she is then fucked by Cole also. Mary says, "I guess we have a couple of very happy girls now that they both have been fucked and can fuck from now on and their brothers I would imagine are also happy that they will be able to fuck their sisters and me. There is one thing that I didn't tell the kids today. I called my sister and told her about what I did today with them and her and her family is coming over." Frank says, "Holy shit you mean that you told your sister about fucking with the boys?" Mary says, "It's alright honey, You see Grace and John fucks with their kids also. I found out about it about three weeks ago from her and she had me to come over to her house and try it with the kids and I must say that I love being fucked by her boys. I decided that I had to get you all to do it together also so that I could be fucked by Larry and Cole and I thought about it and then decided to wait until Larry was taking a shower and then I had to go piss real bad and I figured that he'd be peeking to see if he could see me naked and he did exactly what I wanted him to do, and then it just went from there. Everyone went for it just as I hoped that they would. Now we'll be able to fuck with Grace and her family from now on.
