From 1975 my wife Penny and I had been on regular nudist holidays in the south of France. We tried a few in the UK but the weather was never warm enough and it was, by French standards, expensive. We found a really nice nudist campsite north of Marseilles called Rouet and went there for three or four years running. We liked it for a few reasons the main one being that it was new and very modern. The other was that it was very liberal in it's attitude and nobody seemed to bother what you did as long as you weren't a nuisance or disrespectful. Most of the campers were either German or Scandinavian so rowdy behaviour was very rare.
Penny and I enjoyed ourselves there, and casual swinging was acceptable and very relaxed. There was never any pressure and just a wave and an offer of an evening meal and a few glasses of 'Vino Sexo' would often lead to some fun.
At the end of each week there was a beach party with a bar b qué and a huge fire and lots of sex in the shadows. You didn't have to be naked all the time but most people enjoyed the warm evenings and didn't go textile at all.
We had been dancing and having fun and by about 10.30 things started to slow down and people were returning to their tents. Penny and I sat on a log and watched the fire die away and enjoyed our last bottle of wine. We were approached by a group of Germans, 6 lads and two girls all their mid twenties like us. They very politely asked us if we would like to join their group as they had food and wine and wanted to keep the party going for a bit longer.  We could see no reason not to so we all got together and did our best to chat in some version of English/German. It was really nice and relaxed, and the wine certainly helped.
One of the lads came and sat next to Penny. He was a handsome figure and I saw Penny's face light up. It was helped by the fact that one of the girls was eagerly blowing one of the other lads so it was pretty clear how this was going.
He looked over at me and said in not very good English "Your wife, she very pretty, I like to have her, yes?" I was about to answer but in the time it took me to make up my mind and ask Penny if she was interested, Penny had decided for herself. She already had her hand on his crotch and was leaning in to kiss him. There was a collective "Ohhhh" from the German group and I was pretty sure this was a bit of a set up. I didn't mind, and I smiled and nodded my approval at them. I knew Pen wouldn't mind, if she was getting attention she was happy. She had a hold of the bloke's cock and was stroking it gently. I looked at it and wondered if it would ever stop growing. He was working on Penny's tits and they were having a good time.
The remaining girl came over to me and pressed her self against my arm her large tits and warm skin against mine was very inviting and I put my arm round her shoulders and gave her a squeeze.
Penny now had the lads cock fully hard and it was impressive. She looked over at me and just said "Ok?" I nodded and gave her a smile and she stood up pulling the lad up with her. As he stood she dropped to her knees on the sand and gave his cock a rub as she kissed the nob and licked his shaft before sliding her lips over it and into her mouth. The girl next to me was rubbing her hand up and down my leg, and I was starting to get hard. "Your wife" she said" you like to watch her fuck yes?"
With a rapidly growing cock I couldn't have denied it. "Oh yes" I said, "I like her enjoying herself"
She moved her hand to my dick and rubbed it slowly as she laid her head on my shoulder "You like to enjoy me too" she said. "Oh yes I certainly would" I replied and with my free hand stroked and squeezed her tits as she continued to wank my cock.
Penny was now well in her stride and one of the other lads came over and stood next to his pal rubbing his cock. Pen took one look at it and started rubbing his cock too before sucking him as well. She switched between the two cocks one after the other.
This set a trend and pretty soon Pen had all six lads round her either wanking their own cock or had Penny sucking it. She thought this was great fun and was giggling her head off. My girl got up and deftly swung her legs over mine and holding my cock upright lowered her wet pussy down onto me. Her ample tits bounced in front of me  and I buried my face in them and sucked on her nipples. She looked at me and said, " You don't cum yes?  You say when Ok?" I took it to mean she didn't want me to cum up her so I nodded and replied "Ok, I'll tell you when". She continued to bounce up and down and was moaning and talking in German. It was all very sexy.
One of the lads standing behind Penny wanking, said something like 'I'm gonna cum' and with a grunt shot a load all over Penny's back. It landed between her shoulder blades and ran down her spine and into  the crack of her bum. Penny burst out laughing and carried on sucking cocks. This kind of set up a chain reaction and over the next few minutes or so all six lads covered her face and body with spunk.
I had to quickly lift my girl off my cock before I let go and she knelt between my knees and put my cock between her tits and finished me off  there. I shot my load over her neck and cleavage. Penny was still taking cocks in her mouth, and even Herr Back Cummer managed a second load in her mouth.
I have to say Penny looked fabulous as she knelt in the sand laughing her head off covered with loads of cum glistening in the moon light. The lads picked her up and put her back on her feet and then of all things gave her a round of applause. First one then all of us ran into the sea and splashed about having fun and laughing. Penny was able to wash the spunk of her and the lads were picking her up and tossing her into the waves. She was loving it. My girl stayed arm in arm with me and Pen and we went back to the embers of the fire to dry off.
We finished off the last of the food and wine and headed back to our tents. In the morning me and Penny didn't stir much as both of us nursed headaches which isn't surprising given what we drank. Unfortunately we never saw the Germans again. They may not have been on our site or they may have moved on but they were a great bunch and a good laugh.
