A night out turned to lust part 1

My wife and I went out for a few drinks in our local club , there I got talking to a cabby who was on his own , we talked about our sex lives when my wife went to the ladies toilets , we both said that we would love to fuck my wife and his wife at some point in time , any way the night went well my wife Susan got quite tipsy and I said we should go home , so decided to phone for a taxi , then Pete the cabby said he'd only been drinking non alcaholic beer and that he'd take us home , so I agreed, and on the way home , Susan fell asleep and I told Pete that I loved to fuck her arse , it really turned me on and that it would be good to see another man's Cock in her mouth and as I said that Pete pulled up outside our home and Susan woke up as we pulled up , I thanked Pete and said we should meet up sometime.
Susan went into the lounge and just flopped over the arm of the settee drunk, as she did that I got an overwhelming feeling to fuck her nice round ass , so I put my hands up her dress and pulled her tights and knickers off and threw them to one side , I took my pants off and had a really good hard on , I rubbed my cock on Susan's pussy and she just moaned something that made no sense , I took my cock out of Susan's pussy and put the tip of my cock into her nicely rounded arse , it eased in quite nicely, then I really started to fuck her juicy arse ,Susan just moaned with a few mmmmm,s and rŕrrr,s , next minute there's a knock on the door , I pulled my cock out of Susan and answered the door,to my surprise it was Pete the cabby , he asked to use the toilet and i said sure , it turned me on to know someone else was here so I went back inside the lounge and continued fucking Susan's arse .
Pete was leaving and put his head round to the lounge and seen me buggering Susan , next thing he had his cock and pants off and put his cock into my wife's mouth ,well I've never been so worked up in my life , Pete the suggested that we change positions, so I agreed , as I slipped my hard cock out of Susan's arse Pete slipped his big cock in and started pounding like it was his last day on earth , I started fucking her mouth , we kept fucking Susan till the early hours and at one point I got Susan to to get on my cock as I lay on the carpet whilst Pete fucked her now used arse hole , she was filled with plenty off cum in all her holes .
Eventually Pete went and we agreed to it again with his wife and some point a foursome
