At 30yrs old I married Beth, a cute little girl of 18yrs. My main worry was that she would get tired of me and be wanting 'friends' of her own age.

Well that didn't happen, and after 2 years we are still very happy. Though the worry of her wanting younger guys played so much on my mind that it became a fantasy, which grew and grew till I wanted it to happen. I kept imagining her being fucked by other men and would get off on it whilst we fucked. The images in my mind were like a movie show of her letting strange men use her body.

We used to go out dancing once or twice a week to a local hall. She loved to dance. Whenever she had had too much to drink she would get all romantic on the dance floor, resting her head on my shoulder whilst I discretely felt her up. She really loved that.

We went on vacation and we were having a wonderful time at the beach and sightseeing when she reminded me that we hadn't been dancing for weeks. I asked at the hotel desk if they could recommend a dance hall. The concierge, a young black guy, told me about a place that was only a 15 to 20 minute walk away. But! He warned, that it gets very, very crowded and the dance floor gets packed like sardines and often people get felt up by strangers whilst dancing. Well that sounded like fun to me but I thought I better leave that bit of information out whilst telling Beth.

She was really pleased when I told her we could go dancing that evening. She dressed really sexy, short black mini skirt and white top that was low cut in front. She doesn't wear a bra as her breasts are small but very firm. And of course her favourite red high heeled shoes.

The dance hall was pleasant enough, not crowded at all. We had a lovely time dancing and drinking. As the evening wore on, Beth got more and more 'happy' with all the Martinis she was putting away. The place was also filling up and by 10pm it was as packed as the guy had said it would be.

We were quite packed in on the dance floor, so I took the opportunity to feel Beth up as I was sure that no one could see as we were surrounded by other couples. The music now was all slow songs, so there was a lot of smooching going on all around us. I had my hand down between us and up inside Beth's mini skirt. I was just gently rubbing her pussy through her thong. Not enough to get her over excited but just enough to have her murmuring in quiet passion as she rested her head on my shoulder with her eyes closed.

I too had my eyes closed for a minute or two and I was startled when I looked up and saw a man standing right behind Beth. He had wedged himself between us and the couple behind, he was facing them and I could make out in the dim lighting that there was some movement in his arm, so I could only assume that he was touching up the wife in front of him.

The girls husband must have had enough and suddenly spun his wife out of the mans reach. The man then turned and was facing us. Well I say us, actually he was right behind Beth and he was already rubbing himself against Beth's bottom. She was quite unaware that whatever it was that was happening wasn't being done by me. I said or did nothing to stop the man. My dick sprang into action as I saw that he was easing her miniskirt up baring her bottom to him with only the string of her thong in his way.

I still had my finger on the thong in front when I could feel it being pulled to the side. He was removing any obstruction to her pussy. I now had my finger on her bare pussy as the thong had been moved right out of the way. I then noticed that he seemed to stoop lower, presumably to line up his cock with her pussy. He then rose up a little and started to move up and down in a rhythm that could only mean that he had found his way in and his cock was now inside my lovely Beth. My dick ached it was so hard.

I still had my finger on the front of Beth's pussy. I tentatively moved it forward across her juicy pussy lips and sure enough, I touched his cock and could feel it fucking in and out of my lovely wife. I then felt something touch my chest; it was the back of his hand. He had reached up under her top and was groping her tit.

I wanted so much to get hold of my own dick, I was aching to cum. This whole thing was more than any of my fantasies could ever have hoped to be. Beth moaned a little more loudly and grunted a couple of times in time with his thrusts. Although quite drunk she was experiencing some pleasure from the strangers cock fucking her.
