I had wanted to share Sarah from the early days of our marriage ,but I had only hinted at it to her and she laughed it off .

Well to cut a long story short the years passed and we drifted into late middle age and I thought it would never happen ,I had to be content with watching 3 sum porn and yes wanking to fulfill my fantasy .

I still hinted about my fantasy when we occasionally made love but these times got less and less .

However we still enjoyed life and explored the country in a small camper van staying all over ,it was at one site that things changed unexpectedly.

We were parked next to a large motor home which made our van look like a midget ,it was occupied by a sprightly older guy who we later found out was 70 but we noticed him going out jogging along the beach every day .

On our 4 th night at the site we sat outside sipping a nice red wine when this guy happened to pass by and we gave the usual hellos which led to us chatting ,being sociable we offered him a glass of red which led to him joining us .

As we chatted I noticed his roaming over Sarah when he thought I wasn’t looking , she was dressed in a pair of tight jeans and a tee shirt the usual camping clothing .

Her large breasts were evident under the tight shirt and her curvy backside was on show as she excused herself to go to the toilet block , I watched as our drinking companion tried to hide the fact he was watching as she walked away hips swaying .

He caught me looking and laughed saying you lucky bastard .

I grinned back taking it as it was meant ,then was surprised as he said with a grin do you ever share her ?

I a bit shocked muttered no ,then surprised myself by telling him about my fantasy .

He listened then said want me to try my luck ?

I laughed the wine going to my head and said he was welcome to try ,thinking that was as far as it would go .

Sarah came back and asked if she had missed anything .

Bill our new friend grinned and said Ian was just telling me about his fantasy .

Sarah just gasped and said really ?

I said think it was the wine talking ,but I am game I said laughing .

So am Bill smiled ,then told us how he had done a bit of swinging a few years back .

We chatted Bill telling us about his experiences ,and how some couples enjoyed having a bull join them .

Sarah listened as he talked and I could see despite herself she was getting curious .

We realised the night was getting colder and it was time to go inside ,we got up to say good night but Bill suggested a nightcap in his large motorhome .

He laughed and said promise to behave to Sarah ,and we followed him into his motor home .

The chat continued with Bill starting to flirt with my wife teasing her that she could still make a old man happy .

He laughed and told us it had been a long while since he last had sex but he was still all in working order .

We sat on the comfy seating me next to Sarah Bill opposite and we both found ourselves relaxing in his company .

I said I need to use the toilet and left the camper to go to the camp loos even though Bill said I could use the one in his camper .

I took my time leaving my wife alone with him ,wondering what they were talking about , almost hoping Bill would try his luck with my wife

I made my way back opening the door to find Bll topping up Sarah’s glass using it as an excuse to take my place next to her .

The chat continued Bill getting closer to my wife and casually slipping his arm across her shoulders ,she looked at me sharply but I just smiled .

Well he smiled it’s nearly bed time anyone coming ?

With that he slid a curtain back that concealed a fixed double bed in the rear of his motor home .

Bill then said am going for a walk for a few minutes feel free to chat use the shower get comfortable ,if you are still here when I get back I will know it’s game on .
