She had been going out on dates and she found this man that that she really liked and who liked her as well. They kept dating for about 4 months and the man Carl, finally asks her to marry him . She accepted his proposal. Lisa 's daughter, Sue and son Alan also liked Carl. Lisa and Carl decided to get married by a judge and not go for an elaborate wedding. Things went along fine for the couple for the first couple of months and then Lisa got involved with the P.T.A. and was always having to go to the meetings. Carl would stay at home with Sue and Alan, Then one night right after Lisa left for her meeting Sue comes out of her room and goes to the living room where Carl is watching TV. Sue , who was 14 was only wearing a skimpy bikini and the skimpy bikini was nothing but skimpy. The bra part was just a piece of cloth about an inch wide and went across her tits and covered both nipples and only part of her aureole and the bottom part was about an inch wide at the top part and the triangle tapered down to nothing . It was just enough to cover her slit, except she had it pulled up into her slit with her pussy hair showing on each side. She says, 'Hey Carl How do you like the looks of my new bikini, Do you like it. He gasps at seeing her and says, 'Holy shit, That's a bikini? It don't look like you even have anything on. That's some bikini. I especially like the looks of the way you have the bottom part pulled up into your slit and letting the hair hang out on the sides. That really turns me on. seeing your pussy hairs showing like that." She says, 'Oh You do like the looks of that huh? I was hoping that maybe you would like seeing the hair A I giving you a hard on? He says, " No your not giving me a hard on, I already have a hard on ever since you first came in here wearing that bikini. She says, "Tell you what how about you letting me see your cock and if you will I'll remove my top and bottom of the bikini and you can see me completely naked. Would you like to see me naked?" He says, I would but your mother wouldn't approve of me seeing you naked. I doubt that she'd approve of me seeing you in that bikini especially with your pussy hair showing like that. She moves over to him and begins rubbing the front of his pants right in the cock area. He says, "Please don't do that to me or I'm going to be cumming in my pants. She stops and says, "OK I'd rather have you cumming in my mouth. What the fuck is the matter with you, Mom won't know anything about us unless you tell her and I doubt that you would do that, she says, I'll make it even more tempting for you and take the top off and you can see my titties completely naked He says, Please stop this I'm ready to pop my nuts if you don't stop this, You know you don't want to cum in your pants and Mom see the stain in your pants . Come on Carl take your cock out and let me suck you off and you won't have the stain in you pants." He say, "Augh shit OK you win, and he pulls his pants off and she grabs his cock and she sticks it in her mouth and begins sucking him off. He cums in her mouth and she swallows his load. She says, 'Well I enjoyed that very much Carl, Next time you can fuck me." He says, "NEXT Time, You mean that your planning to have me do this to you more than just now. She says, " I don't plan on having you fuck me all he time, only most of the time. I'm going to want you to let me and Alan fuck together also when Mom isn't around." He says, 'Holy shit you want Alan to fuck you also. " She says, " When I have him fuck me and not you he can suck your cock and suck you off." He says, "Shit I 'm not a Homosexual and wanting to suck or be sucked by a boy. She says, "I know that but your probably Bi-sexual and like men and women or you wouldn't have married Mom and there's nothing wrong with sucking a cock Their good tasting especially when you take them all the way and swallow the cum out of them. He says, 'I don't know, I have never sucked a cock and I don't think that I ever will. Just then Alan comes down from his room and sees Carl naked in front of Sue. He says, "Holy shit what the fuck is going on here. Have you been sucking Carl's cock, Sue? Can I suck your cock Carl?" Sue tells him that she has already sucked him off and you'll have to wait until he gets recharged that you can go ahead and suck him off. Carl says, "I didn't say that I was going to let him suck me off. She says, 'No you didn't , You said that you wouldn't suck his cock but you didn't say anything about him sucking your cock. Alan loves sucking cocks and also to have his cock sucked. C'mon Alan and I'll get you off now. Then we better be getting back to normal. It should be getting close to time for Mom to be getting back. They continue too fuck together for the next two months and Sue's Mom don't catch on about it and Carl doesn't tell her anything about them fucking together, By now Sue has talked Carl into sucking Alan's cock and now he enjoys doing it with Alan also This went along for another month or so and then when Lisa was gone to a meeting and they were fucking together, the doorbell rang. Carl throws his pants on real quick and answers the door and it is Lisa's sister, Alice and husband, Fred and their kids. They tell Carl that they were just in the neighborhood and thought that they would stop by and see her sister, but what she saw was much better. Carl asks her what she means and she tells him that they had heard moaning as they were coming up the walk and looked in the window and there is a crack in the curtain and she saw him fucking Sue. Their kids also saw what was going on and now want to know if they can do that also with their Mom and Dad. Alice said that she would like to do it with Carl herself and their son, Hank said that he would like to do it to Sue. Alice says, 'Would you mind if we was to join you in your endeavors with Sue. I'm sure that Fred wouldn't mind fucking Sue while you fuck me and could maybe suck off Alan or vice versa. You see Carl we fuck together all the time and it would be nothing new to us, except a new cock to fuck me which I would love especially with what I saw of your cock. He tells her that he wouldn't mind fucking her as long as she doesn't mind and that Sue wouldn't mind being fucked by Fred, he then tells Alice how Sue first got hm started into fucking her and about her skimpy bikini. Lois asks if she can see the bikini and Her and Sue goes and Sue puts it on an pulls it up into her slit again. They go and show Alice and Lois says, "Mom I have to have one of these bikini's. Alice says,'Why would you want one of these you don't even know how to swim . Lois says, 'Yeah Mom but it would surely give all the guys that see me in it a hard on and want to fuck me. Alice says, "Yeah I hadn't thought of that, Maybe I'll see about getting me one of these also and maybe we can recruit some new cocks to play with. Alice tells Carl to get his clothes off again and fuck her, He does and begins by sucking on her titties and then he eats her pussy and finally fucks her and cums in her. While they are fucking Fred is fucking Sue and he also cums in her as well. Alice asks him where Lisa is and her tells her that she has a P.T.A. meeting every couple of weeks. Alice says, "I'm going to have to remember that. Would you mind if we was to come back here in two weeks when she is gone again Carl and the kids tells her that they would love to have them all come back. They all get dressed and they leave. About a week later Lisa goes over to Alice's house and and Alice asks her what's the occasion for the visit and Lisa says, 'Shit can't I just visit my little sister, after all it's been a while since I have seen you. Lois comes out into the kitchen and sees Lisa and says, "Aunt Lisa are you going to be joining us anytime soon, Hank would love to get you." Alice tells her to get out of here and go play with her brother or something. Lisa says, " What was that all about wanting to know if I was going to be joining her. Alice says, 'Who knows what goes through her mind. They talk and then Alice goes out of the kitchen and when she is gone Lisa notices the calendar on the wall. She notices that it has what looks like Lisa marked on it and goes over to it and sees, 'Lisa Gone' marked on every Thursday for the next couple of months. Alice comes back and Lisa is back in her chair. They talk for about an hour and a half and finally Lisa decides to leave. She wonders why would Alice have 'Lisa Gone' marked on the calendar and then she realizes that Thursday is her night for the P.T.A. meetings. She begins to wonder if there is any connection. A couple days later is the Thursday for her meeting and she leaves. But she doesn't go to the meeting she drives around the block and parks about a Block away from her house. Then about five minutes later she sees a car pull up outside her house and it's her sister and her family that gets out of the car. They go into the house . She thinks to herself, "What the fuck is going on here, Why is Alice going into our house while I'm gone. She goes to the meeting and doesn't says a word about seeing Alice come to the house to Carl or Sue . She let it go and then two weeks later was time to go to the meeting again and she does the same thing, drives around the block and parks about a block away and sure enough the car pulls up in front of their house again and Alice and her family get out and go in the house. She waits for about 10 minutes and decides to get out and walk to the house and find out what is going on in there. She can hear noise in there and she looks in the front window and there is a little crack in the drapes and she can see Alice and her family and Carl ad Sue all naked and fucking together. She thinks, 'So that is what is going on. I wonder how long this has been going on between Carl and my sister and how did it get started with them together. She digs out her door key and goes into the house and goes to the living room and ask if they are having fun together. They all scramble to cover their nakedness. She tells them not to bother that she knows what a cock looks like and the one you have don't look that much different from Carl's cock, Fred. and I enjoy seeing Carl's cock and I don't mind seeing yours either, I hope that don't make you mad Alice, but since you've been working with Carls' cock. I guess it doesn't really matter if you like it or not. Since you've been fucking with my husband, I'm going to start fucking with your husband. Alice tells her that she's glad that she knows about them and that she has felt queasy about fucking with Carl behind her back. Lisa asks how did this all get started . Carl jumps in and tells her how it all got started with him and Sue and then Alice and her family caught us fucking together. That they have been fucking together for about 4 months with Sue and Alan and about month and a half with Alice and her family. Lisa says, "Well since you all have been doing it for that long I have a lot of time in order to catch up to you all. Lisa then starts taking off her clothes and is soon naked also. She goes over to Carl and tells him to let's go he is going to be her number one fuck. They do go at it and Carl cums in Lisa ad Lisa loves it ad says, 'Shit this is gong to have to be at least a weekly party and maybe even an every other day one. I wouldn't mind it being every day but I'll give you guys a day to rest. They continue to fuck together from then on and usually are at each others house about 3-4 times a week.
