I live in the UK and in the early eighties I went on a camping holiday to the west coast of France with my wife and two small boys.
I did not realise how different the French are to us, especially in the way of nudity.
The showers on the site were communial although they did have cubicles but with no doors.
They did have a couple of single shower rooms you could use privately if you wanted.
Then the main surprise was on the beach which was nudist if you wanted.
Sorry about the long intro but it sets the scene for what I am about to tell you.
My wife took my two boys down to the sea to paddle and I just stayed laying in the sun when two women in their 20's came and settled down about five yards from me.
One of them, who was very fit, stripped naked and it was the first shaved pussy I had ever seen except when my wife had had our first when they shaved her in hospital, they did that in the early seventies.
The other girl stripped down to shorts and tshirt, she was plump but still quite attractive.
The naked girl was lying on her stomach and the plump girl started to apply sun cream to her back.
I, by now, had to roll on to my stomach but my cock was bursting.
The plump girl then started to put suncream on the other girls bare bottom and then let it run into the crack of her bum. The girl opened her legs and the plump girl started to masturbate her right in front of me, very quietly and discretely.
My prick was now bursting and I prayed that my wife and kids would not return yet.
The naked girl then started to moan softly and the plump girl kept rubbing her between her legs.
This was the horniest thing I had ever seen and I was like iron and ready to burst when the naked girl let out a soft but slighly louder moan and arched her back, this was too much for me and I came in my swimming trunks what felt like a gallon of cum.
I was soaked.
The plump girl looked at me and winked and I gave her an embarrassed smile back.
They had put this show on for me.
The plump girl sripped off down to her bikini bottoms only, she had lovely big tits, and they both went off down to the sea.
I could hear my kids coming so I had to rub sand in and out of my trunks to try and hide the evidence of me cumming which I think I did successfully. I went into the sea to clean myself off properly.
Later that night when the kids were asleep I had great sex with my wife thinking about my 'friends' on the beach.
One other thing happened on that holiday and I will tell you about it again.
