my wife is 33 and very pretty, size 10 with lovely long blonde hair, im 40 and love her very much but have wanted to see her act like a slut with another man for a long time now, shes always liked to talk about it but would never actualy do it untill the day i met peter, he is 50 yrs old slim and fit for his age, wed been going through a slow patch as far a sex went, a bit boring and predictable for both of us and id met peter through my work, anyway i found out that he was into swinging and had seen quite a few cpls in the past, i told him all about my fantasy and he said he was sure he could get her to go along with it as he new just what kind of things to say to her,he asked if i had any pictures of her so i showed him some the next day of her naked or in just her stockings that shed let me take a while back,he said she was fantastic and got very exited, we arranged for him to come to the house one night on the pretext of work,i got some booze in and before he arrived plyed my wife with a fair bit to drink till she was fairly merry,the one thing peter had warned me was that once shed had his cock once she would want him more and he could get her to be much more daring but i thought he was just bragging and said great lets do it, any way he arived and to cut along story short he was amazingly charming and i could actualy see my wife likeing him and when he steered the conversation to sex she readily talked openly to him which was not like her,she was getting a bit drunk by now and i went to the toilet, as i came back i looked through the door to the living room and he was sitting with her and had his hand up her skirt as i walked in she pushed him away and tried to make out nothing was going on,he winked at me and went to the toilet ,i asked her what shed been doing and she said nothing as though she was offended,i told her it was ok and i realy wanted to see her with him,what with the drink and his charm she just agreed but said it would just be a one off,at that peter walked in bollock naked and i know its always said but his guy s cock realy was big it was rock hard and he was stroking it all 9inches of it, my wife just gasped ,he told her she was lovely and that he new i wanted to see him fuck her, then he stood her up and undressed her ,i just sat back and watched ,he kissed and played with her tits then lay her on the sofa, opend her legs and fingerd her ,after a while he knelt down and slid his cock in her gently bit by bit till he was up to his balls, iwas wanking my own cock by this time and after a long while of fucking her slow he started to realy ram her hard, she had her legs up over his shoulders and was moaning in exstasy,it was fantastic to watch and towards the end he told he had had the snip so could he spunk up her? she just moaned and said "do what you want im loving it" and then he grunted and shot up her for what seemed like ages, she orgasmed and i could realy see she was loving it, as he pulled out of her some of his spunk came out and went on the sofa, her cunt was very open still and coverd in his sperm ,after a long talk he persuaded her to let him come around again the next week end and then left,she was still horny so i took her to bed and had the best fuck for ages, there is a lot more to what were doing with peter now but ill tell more at a later date. to be continued........
