Me and my wife Caroline and me are both 41,we have been together 16 years,we got married 10 years ago.Caz is 5'2'' tall shoulder lenth brown hair size 10 and 36c size tits she has kept her figure well due to not having any kids and regular trips to the gym,and can still turn heads,i am slim 5'10 with brown hair.We have a good sex life and because of my low sperm count we never need contraception.Caz had two previous lovers before we met and was very prim and proper when we first got together but it all changed after this experience i am about to tell you. We had been living together about two years and we were invited to a birthday party,it was in a different town to were we live so we decided to drive to the party,stay in a b&b and drive back the next day so we could both have a drink. On the day of the party we were driving up the motorway, wearing the clothes we were going to wear that night to the party i was smart but casual and Caz was wearing a dress that stopped just above the knee and a jacket,no bra but she was wearing knickers,stockings and suspenders. As we drove along the motorway Caz said all the lorry drivers were staring at her,i told her they were looking at her legs as her skirt had rode up as we were driving along.I asked her if she liked the divers looking at her legs and she said yes So i pulled up along side a lorry and stayed at the same speed as him giving him a good eyeful.I reched over and pulled her skirt up more showing her stocking tops and my hand reached her knickers pulled them to one side and slid a finger in her cunt.Caz's pussy was rearly wet so she must have enjoyed giving the driver a show.All to soon we reached out junction of the motorway so we turned off the motorway and headed for the party. The party was great and when it finished me and Caz went back to the b&b.As soon as we got to our room we started to get undressed quickly and started to fuck,as we fucked i was talking about the lorry driver and Caz got very exited and came almost straight away and this sent me over the edge and i cum too.As we lay there cuddling after i asked Caz why she got so exited when i mentioned the lorry driver and she said she liked the idea of another man wanting to fuck her, so did i and i told her she just said it will probably never happen then she rolled over And went to sleep. The next day Caz went shopping for an hour before we left so i sat in a cafe while she shopped about an hour and half later and phoned my mobile to pick her up.She had her long coat on when she got in the car and as we drove off she said i got something for the lorry drivers to look at,then she took her coat off.I nearly crashed the car when i saw what she was wearing,She had a new black dress on that you could never go out in as it was very revealing and was was made of satin and it was very i could already see the tops of her new hold ups and she never had a bra on.i asked her if she was wearing any knickers and she said yes. We turned onto the mororway and Caz was loving it showing off to the lorry drivers flashing her legs and her body looked great with that dress on.After about three miles the traffic slowed down and we were just crawling,there was a lorry right next to us and as we pulled level with his cab Caz looked at the driver and said the driver was only about 20 and looked nice.He opened his window and said could we pull off at the next sevice station but Caz just laughed ad wound her window back up.She turned to me and said i dont mind him looking but if we stop he will want to join in,i told her we could lock the doors and he would only be able to look and if we didn't like it we could drive off.Caz thought for a about a minuite then wound her window back down and shouted to him 'watching only' and he gave us the thunbs up to say ok.The traffic started to speed up and i pulled up in front of him so he could follow,we turned off at the services and parked in the corner off the car park and he pulled along sie us so no one could see us.He got out and came to my side of the car and i opened the window and said to him watching only mate he said ok but can i wank,i looked at Caz and she said he can if he wants to so he walked round to her side of the car and started watching.Caz then reclined her seat so she was nearly lieing down so i leaned over and started kissing her she reached out and got my cock out and started wanking me.my cock was hard as steel and caz gave an approving moan,i was feeling her tits through the dress then i just got them out and started sucking them.As i was doing this Caz was looking at the driver and said to me that he was getting his cock out,his cock was not big but it was bigger than mine(i'm six and a half inches)And Caz never took her eyes off it.I pulled her dress up so he could see her knickers,she was wearing a small silky thong but she was that wet it was transparent and he could see her pussy through the material,i pulled it to oneside and pushed three fingers straight in she was soaking.Caz then took her eyes off his cock looked me in the eye and said fuck me now so i got in the footwell lined my cock up and slid in balls deep she was that wetHer cunt felt so hot yet so wet at the same time,after ten strokes i knew Caz was about to orgasm her breath quickened she arched her back and kept shouting 'don't stop yes yes yes fuck me harder fuck i;m cumming' then she started shaking and gave out a moan of approval.as her orgasm washed over her it was too much for me and i cum up her cunt.We looked out and lorry driver was still wanking away I said to her jokingly pehaps he needs a hand and Caz said open the window and i'll wank him off i said would you and she said i will if you want me to so i pressed the button and the window went down she then said to lorry driver come here and i'll give you a hand so he came up to the window and stuck his cock throught the window.Caz wrapped her hands around his cock and started to wank him as i watched rfom between her legs my cock was hard again so i pushed it back in her pussy and got into a good rythem.Caz was moaning how good it felt as she kept wanking him and i kept kept fucking her,after a bout five mimites of this Caz started to show signs she was about to cum again so i rearly started to fuck her fast,then the lorry driver said he was going to cum,Caz started shaking but somehow mannaged to keep wanking him off.lorry driver then cum four hot spurts of spunk shot out and landed on Caz's tummy and dress then i started to cum too so i pulled out and shot my spunk into the same place lorry driver had.The driver said that was great put his cock away and went back to his lorry.We tidied ourselfs up and drove home.As soon as we got home we started fucking again thinking about what we had just done.I told her i wanted to see her suck the lorry driver off and Caz said maybe next time,well there was a next time and many more times.I'm not cuckhold we still fuck and i have watched her fuck another man and she has also seen me fuck other women so if this story gets on swingers heaven stories i'll write down some more..........so keep looking.
