Last year we had one of those spells of warm weather and my wife Christine and I thought we would go down to a naturist beach not to far away in Kent.We arrived at the beach and it seemed pretty quiet just about a dozen people spread over the beach still it was a weekday,we set up a windbreak put our towels down and stripped of to enjoy the sun after about an hour or so I sat up to look around and could see that it was still quiet except for a man about the same age as us late fifties walking passed, as he got to where we were sunbathing he said good morning and we started chatting about the beach as he was a regular and this was our first time it was an interesting conversation.As it was getting hot I asked him if he would like a cold drink from our cool bag he said ok and I said why dont you sit down and pointed to the sand,we chatted for a while and we seemed to have a lot in common I noticed that his back was getting quite red with the sun and said you should put some lotion on he pulled out the suntan oil and started to rub it in but when he tried to do his shoulders and back it just ran down and he could,nt reach to do it properly as christine was nearest to him I said rub that in for him she looked at me a bit funny but then said to our new friend John lay down and I will rub it on your back for you,watching her squirt the oil on Johns back and rubbing it in was starting to turn me on and I felt quite a hard erection starting when John sat back up I was feeling a bit embarrassed but I did notice that he was quite hard as well we all looked at each other and just smiled I dont know why I said it but I said to Christine we could both do with a hand here I thought to myself what are you saying but they both looked at me and John said well I dont mind and to my surprise Christine reached over and started wanking him off I was so turned on now that I just played with myself while I watched them both it had allways been one of my fantasies to watch her with another man.I let go of myself and reached over to christines pussy which was soaking wet she was really turned on I then felt a hand on my dick and to my surprise it was John, well I had allways been a bit curious so I let him get on with it,There we were the three of us Christine wanking John and him wanking me and I was fingering Christine and trying to make sure nobody could see what was going on, I came first watching the two of them was to much for me then John came all over Christines hand I started to clean up while John carried on fingering Christine until she started moaning and then came as well.we were just in time as some more people started to walk towards us so we just all layed down as if nothing had happend.When it was time to go John said if we were comming down to the beach again give him a call and handed me his phone number but that will be another story.
