We are a ordinary married couple, we have done quite well over the years with things like houses moving making money out of it that has stopped now we also have good jobs The thing with us we have and always had a good sex life unlike what I often hear from other husbands, so we are pretty lucky This all started after the last kid went to uni, we often talk about things we like to do in bed, it always end up with us having a session, what we talk about are fantasy situations there are a rang of things but one has always come up in some different forms but basically the same sort of thing on much the same lines it involves other men or a man with Sandra my wife, it can involve me or I am watching , we both know in reality it would never happen so its easy to say any thing we like to each other and know its jest fantasy As I said after the youngest one when to uni,we where doing our usual thing one night, I had got Sandra really worked up,and was telling her this bloke was going to fuck her and I knew she may struggle to take him he is enormous and so on We have a rabbit vibrator which is larger than me and I used that on her, I rammed it into her she almost squealed out then cried out harder she climaxed almost immediately she was really worked up, what she said next was a little unusual for her, it was oh god I want a big cock to fuck me, she said it as if she meant it as she climaxed again I was bursting I pulled her onto her knees and fucked her from behind as I did that I pushed two finger up her ares which made her ground out loud with excitement I wasn't long cumming, this wasn't some thing that was unusual for us we did this sort of thing a lot not always the some but on then lines It was afterwards we where having a cuddle and Sandea was saying how good that was,so I said well maybe we will have to get you a stud to do it properly I have said that hundreds of times I was surprised by what her reply was, she said we could do that now we don't have kids at home. it wasn't said in the heat of passion it was in the after glow Next morning we where having a coffee and Sandra asked if we did that for real what would happen,I said you get fucked thinking she was joking, she said no silly if we did have some one do it, I was more than surprised by this she seemed serious and it seemed she had thought about it, I flowed on by saying what do mean what would happen, she said with us if we let it happen its very different from doing what we did last night and talking about it to get us horny, this then lead on to a very surprising discussion for me at lest, Sandra a few years ago would never entertained the idea or talked about apart from our games in the bedroom, now it seemed she maybe sirius about the idea There be to much to go into on here about what was said, her worries where our relationship as a married couple if it happened would we be able to keep it discreet,I pointed our the question of conception as I have been vasectomized and we don't use any She said well we have to use condoms and I would most likely go back on the pill to be safe, so she had put some thought into this Over the next week or so Sandra brought the subject up a couple of time, we where thin talking about how would we go about it, and if we did who would it be, I was finding the idea really horny but if we did do it what may happen afterwards because Sandra had said she have to really fancy the other bloke would she get to involved with him and that course a problem, and would I be jealous and how would I feel or react to another bloke shagging my wife It didn't take long and we where looking into the possibilities of it really happening Sandra took the step of going on the pill she told me one evening what she had done, I think that was the point I knew she was siriu, before long it was who was it to be, she discounted our friend or any one we knew, so where would he come from it left going out and meeting some, that idea was flooded as we would have go outside the area The internet seemed the answer and it didn't take long to to find sites like this one infact this was the one we used in the end The idea was ideal you look first a bit like shopping, so an advert and profile was got together and then put on the site The replys rolled in loads of them, after spending time looking st them Sandra seemed to get a short list together,then it was messages which discounted a couple of them in the end it came down to two possibilities they where emailing each other then she was on the phone to one of them, Sandra seemed to like him his name was Graham in his mid forties so a little older than her, he was divorced also he was experienced he been into swinging some time, I asked why him she said well I fancy him and his not like a lot of them on there, a lot of blokes seat pictures jest of there dicks not of them with face on the photos also he didn't want to meet the next day he asked about her and us it was more like he chatted her up in a way, after a could of weeks of this it looked like it was on the cards we whee going to meet in a pud close to where we lived, this was all Graham's idea he wasn't pushing Sandra or us into any things as he said we meet and chat and see how things go On the evening of the meeting I came home with a packet of durex and gave them to my wife she said I don't think it go that far, as we walked down the road we where both as nervous as hell, in the pub no sigh of Graham we got a drink and waited fifteen minuets late he came in he said he got lost, we seemed to get on right away he was very polite after an hour or so he said I go to loo and be a few minuets and you two can have a chat It was what do you think do we or not, we where still say that when he came back, after he sat down Sandra surprised me by saying we would like you to come home with us she had made her mind up it was out of my hands it seemed At home we sat in the lounge talking, I was wondering what would happen we not really talked about this part, I think Graham had sensed this, he was sitting with Sandra on the sofa his arm went round her shoulder she tensed for a second and looked at me not long after that Graham moved her head round and kissed her, in a few seconds she was kissing him back, once that happened it gave Graham the green light things moved on quite fast I was a bit shocked to fine my wife was that willing the way they where snogging and touching each other she didn't mind when he undid her blouse and when her bra was pulled up she stopped him and undid it for him, it was a bit unreal forme to see my wife toplee getting her nipples sucked in front of me, she was also rubbing his couch By then it was obvious things had gone to far to stop at jest petting, she had undone his zip and had had a hand inside, the strange thing I had a hard on watching this but I had a bit of a shock coming, when Graham eased his taurus down to give Sandra more room I expected him to have pants on but it wasn't that it was what my wife had her hand round I knew his profile said no complaints I could see why he had a semi lob on and I guess it must be a good couple of inches longer than me but its width was huge it was twice or more as wider than mine, I think it surprised my wife she glanced at me then back at his cock, she did no more about but picked it up bent down and took it in her mouth she was licking and sucking the end as she did that it grew and swelled when it was fully hard it had to be a good three inches longer than me and her hand only jest went round it I think if she held it lower down her finger wouldn't of meet the bottom half was very wide Graham stopped Sandra sucking and said would you like to show me your bedroom, with that she stood up fallowed by him it was a unreal sight my wife topless a man with no trousers sporting a hard on, it looked huge to me big and long with a curve back towards him it bounced as he walked Out the door and upstairs they went with me fallowing to our bedroom inside he stopped Sandra by our bed and kissed her with that thing pressed between them I was now witnessing how experienced Graham was also how dangerous it is to let a wife go with a real stud and how he may rune her for ever as was about to happen in this case I was now starting to see Graham was in charge some thing quite new to Sandra I think but it looked like she was enjoying it Graham was taken his time, he kissed her neck and caressed her breasts before spending time sucking each nipple he really got them to stand out very stiff. it was amazing the expression my wife had on her face some thing you don't see if you do it, he obviously bit them a few times it made her gasp, as he did that, he eased her skirt down she had black hold up stockings on and she looked sexy, after given her breasts a lot of attention he went back to kiss her, this time his hand went between her leg she parted them for him I couldn't see what he was doing but I herd her moan in his mouth He then slowly and gently lower her onto the bed, I would say his cock looked harder and maybe bigger than ever now, there was another snog, he then started to tug on her knickers she lifter her bum and he got them past her thighs then off her feet I was amaZed at my wife she opened her legs knees bent, as if showing him her pussy one hand went down to it and touched it she played with it for a moment it looked very wet Graham parted her legs more getting himself between them he was bent over as he started to go down on her I was at the back of him and got a good view of his balls he has got some pare of nuts like two chickens eggs in a sack hanging there they looked over sized in a way Geham spent a long time licking and sucking a very excited woman he gave her at lest two climaxes, he made sure she was ready for what was to come and I would say my wife was gagging for it, he got on top of her holding his cock about to force it into that tight space which is my wife's cunt, I was about to watch him rune my wife but I didn't know that at the time, she lay still as if waiting legs wide apart, he seemed to fumble for a second or two then Sandra gasped I then heard her say Jesus out loud as he pushed he got it inside her and she knew it was there, I moved round to get a better view he had about half in her it looked like it really stretched her pussy, he was about as far as the rabbit can go by then there was three or more inches that would going into her virgin territory,I would think from then on it be narrower and much tighter, Graham must of felt that he seemed to put presser on slowly his mead moved into my wife she was making all sorts of noises moaning and gasping he was to close to Sandra for me to see now, he seemed to pause then move back an inch or two, then gave a hard thrust she went AAAAAH Jesus My wife must of had his full length she lay there panting and he lay still on top of her Then he drew back and then went in again it made her gasp, he then repeated that a few times she gasped each time he bottomed out but she also started moaning it was very obvious she had stated to enjoy the sensation as his movement got a little faster Sandra's legs opened and lifted into the air given him complete access Little did I know or realize that was most likely the moment she became a slut a size queen, he had gone in her deeper than she ever been penetrated touched places that had never been touched before and she would want more of that Graham was now fucking her at a steady pace, she was moaning and obviously enjoying it The movement was a steady rhythm, he was using most of of the length of his dick with each stroke with Sandra laying still taken it, I have made my wife cum hundreds of time time and from the noise she was making she was on the way to a climax, this would be when if I was doing it I would of speed up and that would most likely make me cum but Graham didn't he didn't change his pace, normally Sandra would tense a little maybe gasp as she cums, this was to be very different, she did all that and climaxed but now Graham's cock was still going like a piston in and out of her, she climaxed alright but as I watched she started gasping and moaning she cum again, it was a few moments before she started to tense then her body shook her head rolled from side to side then it seemed she couldn't get her breath she was trembling she gone into a multiple orgasum and Graham had not missed a beat, the orgasum seemed to go on and on, she started to say stop stop her hand on him as to push him off but the cock still keep going inside her, how long it last I am not sure, I think Graham knew what he done and what had happened, he slowed right down my wife was panting under him He seemed to let her rest, then without warning almost he picked her legs up pushed them almost over her, and some how he found a bust of energy after seeing the way he had been fucking I was quite surprised by how fast and hard he went it lasted maybe fife minuets before he grounded the grunted, he was emptying his balls inside her, his ares clinched he jerked a lot, it was only then did I think condoms he didn't use one but where were they still in the kitchen where we left them After Graham had cum he pulled out still holding Sandra's legs up he nodded for me to look as I did he pushed her legs apart so I could see her cunt it looked pinkie in color the lips puffy and rolled back so the slit was quite open and the entrance was gaping as we looked on it was more like a white bubble appeared, then a trickle of spunk ran out I was amazed at my wife letting us do this and more so when Graham let one leg go and then used his fingers to open her up more she still keep her legs open he must of shot a gallon of sperm inside her the amount that was running out Sandra looked exhausted by the experience After a time Graham and me went back to the lounge Sandra showered and then came down I am not going into the conversation but it ended up my wife wanted to see him again and Graham was very keen to do that, at the time I didn't think it was a very strange experience as I was involved in it at the time I did afterwards also I didn't realise it was a life changing experience and how it changed my wife That night all sorts of thing changed from small things like letting a man out of my house that had jest fucked my wife in my bed and me shacking his hand and thanking him for coming round, to other things like I was busting I was so aroused and need sex with my wife which I think she understood and let me I had never put my dick in a pussy so loose and sloppy in my life and the weird thing I really enjoyed it I know I only lasted seconds So that was the start of a new lifestyle for us and many more experiences that fallowed
