Following on from part one Jess is watching over my shoulder as I write this in her words to make sure I get the facts correct. We laid on the beach for a while nothing was said until Jess suggested a cooling dip in the sea, Mark said he would continue to soak up the sun so Jess and I made our way into the water, were in up to our chests when I put my arm around Jess she said you know don't you I put my hand on her pussy and said I do now. Jess said as soon as you were gone Mark asked if I minded him taking his shorts off I said go for it, Mark was laying on his back and I could see his cock getting erect I said to Mark you must be thinking about your girl friend by the state of that. He sat up and said far from it I was thinking of you, ever since I was about 16 I used to really fancy you I used to love the summer parties you and my parents used to have seeing you in short dresses really got me horny. Jess said I am old enough to be your mother although you are a very good looking guy, with that Mark moved next to Jess and put his arm around her and drew her in for a very passionate kiss I tried to pull away Jess said but he was so strong and then I stated to enjoy it by then it was to late. His hand was now stroking my nipples and soon was inside my bikini bottom playing with my pussy and involuntary my hand was stroking his nice hard young cock. My bikini bottoms were soon off and Mark was pushing his young cock into my willing pussy it felt so wrong yet so nice, he did not last very long we he came it was the amount of cum that suprised me he seemed to just keep filling me with his cum and when he pulled out it just kept flowing out although I did not have a orgasam I felt satisfied . Mark lay back on his towel but his cock was still hard and he was slowly wanking it then reality set in I said Mark that should not have happened but he just said he has waited a long time to do that but he was sorry it did not last long and and next time he will last a lot longer I said what do you mean next time and with that we both see you walking back, as Marks cock was still hard he had to lay on his front and probably still is that's why he did not come into the sea with us. All the time Jess was telling me what had happened she was playing with my rock hard cock and my fingers were well buried in her cum soaked pussy, she said I hope you are not angry but my hard cock gave her the answer I think. We made our way back to Mark who was looking very sheepish but Jess reassured him that all was ok and we both explained about our swinging life style, Mark looked so relieved I said the only disappointment for me was I did not see it. By now it was time to go so we packed up and made our way back to the car. When we arrived back at our apartment Jess invited Mark in for a cool drink I thought may be she had a repeat in mind but I was disappointed, but we both agreed if Mark wanted we could all go out for a meal later and if all went well perhaps Mark could stay over for the night, he was more than happy to agree, so we arranged to meet Mark later that evening. When Mark had left I almost tore Jess's cloths off no for play just her legs over my shoulders and my cock pushing up her still very wet pussy for some hard fucking which Jess loves we both came together and lay in each other's arms until it was time to shower and get ready to meet Mark again.
