While on holiday in Portugal with my wife joy and her cousin helen and husband Iain we managed to have a great week of sun and sea and one fantastic night of sex, Helen and I for years had always flirted whenever we were out and on occasions I had felt her bum and she had shown her tits. It was on our last night of holiday we had been at the beach all day and Joy and Helen had on their bikini's an as usual Iain and I sat and emptied all the beer and spirits while watching all the talent on the beach or so I thought. Every time I said to Iain, look at the body on that he would grunt Yeah, but when I looked his eyes were always fixed on my wife Joy. Joy had a bikini top on that really pushed her tits up and looked stunning even though she and I were a good 10 years older than Iain and Helen. I casually said would you like to fuck her and without thinking he said yes. That night after dinner and when the bar closed we all went up to our room and as we got more and more drunk I managed to get the talk to a sexual nature and eventually I said to Joy and Helen,shall we swop tonight for some fun. Both girls laughing said yes. A few drinks later I winked to Joy and she took Iains hand and said come on then stud lets go next door and leave these two. Helen and I had a drink and I started to try and kiss her but she said that they would not be doing nothing next door and it was only a joke they would be waiting to see if we did anything. We then heard the bed banging against the wall and I heard Joys unmistakable grunts as she started to come. I said it dosent sound like nothing to me it sounds as if Iain is sliding his cock right up Joys cunt. We then heard Iain grunting as he shot his spunk deep inside Joys belly as I knew she did not have any condoms. Joy moaned keep going Im coming again and shrieked as she came again. Helen said thats all she will get as he will roll over and go to sleep. Lets show them how its done then as I eased Helens panties off and started to lick her cunt. She came instantly saying she had never been licked before as she always thought it was dirty but could she have some more. Well I licked, sucked and bit her clit for the next hour before she begged me to fuck her. I started to mount her and she said wear a condom but I said no chance Im going to ride you bareback like Iain and Joy did and just rammed it deep into her. As I rode her deep and slow, then hard and fast , then deep and slow again, we heard the bed next door start to bang against the wall again as Iain and Joy fucked again. Helen said the bastard never fucks me twice in the same night, No but I will, all night if you want. I want she said, fill me with your spunk now,I increased my thrusts and exploded deep inside Helen. Great she murmured now I need more. Well that was what happened the whole night, fucking and sucking, We all agreed the next day it was a one off not to be repeated, but me and Helen still meet once a month for a good session
