We are just a normal married couple Jenny my wife of 36 years is 60 and I am 59. We have never tried swinging and have up to now been satisfied with our sex life. Just a bit of fantasy reading the stories on this site, but that all changed recently when we had our first and unplanned threesome with one of our friends. Our friend Pete and his wife Susan came over from the UK to spend long weekend at our house in Spain and on Friday we had all went to the local beach, where up among the dunes where we all were enjoying the sun. Susan Pete’s wife was in here one piece swimming costume, Jenny my wife of 60 was wearing her bikini bottoms only having taken her top and the look on Peter's face when Jenny removed it, his eyes almost popped out as she brought her very ample pair of tits (38DD) into view. We all sun bathed and chatted over a picnic and a few drinks and I noticed how Pete kept glancing at Jenny’s breasts, I also noticed that it was obvious that he had, what looked like massive erection which he was trying to hide. We all had a good time just chatting etc but Jenny whispered that she felt a bit uncomfortable the way that Pete kept looking at here breasts and the fact that Susan was there. I whispered back you are showing them off Susan’s going to sleep let him enjoy, she said he is enjoying look at his hard on its looks huge, its making me feel uncomfortable. I knew then that what she ment was that it was making her randy and I noticed the wet stain showing on her swim pants. Susan Pete’s wife just laid back on the sand and went to slept, I offered to rub on the sun cream for Jenny starting on her back then onto her front, rubbing the cream into her boobs as she lay there snoozing, Pete was looking so I indicated that he might like to help. I put some cream onto his hands and he took over from me, nothing was said while he massaged her breasts and tweaked her nipples her legs opened involuntary and I could see the now very large wet spot. So I put a hand between her legs. She opened her eyes wide, as she must have realised that there were three hands on her, and has we had never shared or anything it was the first time. She could see me but not Pete, only his hands I smiled and said enjoy, Pete was still playing with her nipples and I was pushing on her pusey through her pants. She went to protest but then just laid back, as Pete was massaging her breasts his hard cock was pocking her head and face through his trunks, I motioned for him to take his trunks off, he did this with one hand, his cock sprang into view hard thick and a bit longer than mine. I nodded and he took it in one hand and leaning over Jenny he put it on her lips, the big end dripping a little. She opened her eyes and looked straight at me, I nodded and she just opened her mouth, it was so erotic my 60-year-old wife with another mans cock in her mouth while I rubbed her pusey and his wife slept next to us. Jenny was so wet I slipped her pants to one side and pushed two fingers deep in her she was loving it. Very quietly so not to wake his wife Susan, Pete and I changed places, me at her breasts and he both licking and fingering her pusey. She was moaning yes then she said please some one fuck me, so trying not to awaken Susan we got her on her hands and knees. Pete put his very hard thick cock up against her and went straight in fucking her hard, I pushed my now so hard cock into her mouth, Susan still slept. It was over too quick we all came together, Pete deep inside her, me in her mouth and Jenny over Pete’s cock. We all just tumbled down into a heap just as Susan opened her eyes.
