I was married to Merril and Jackie was married to Alan, and by and large, we were all very happy with our lot.
The four of us had arranged a weekend away on the south coast, but at the last minute, Alan was stuck at work later than expected and he asked if Merril and I could collect Jackie and for Alan to travel down the following day in his own car.
This was agreed and Merril and I picked Jackie up from her house at about six oclock on a Friday evening. She was carrying a large suitcase, which we threw in the boot of the car. She was wearing a t shirt and denim shorts.
Merril had prepared some cold food for us all for when we arrived at our resort, and she was balancing plates of clingfilm covered plates, and plastic tubs full of delicious sandwiches on her knees.
It was Merril who suggested that she should travel in the back seat so that she could have space for all the food. And so it was that Jackie sat next to me up front for our journey.
We set off southbound for a trip that would probably take the best part of four hours. We stopped for refreshments after covering a hundred miles or so, and both girls took the opportunity of sharing a bottle of wine.
We continued our journey and Jackie climbed onto her seat and kneeling, turned around to face Merril while they were talking.
By now the alcohol had taken hold of both girls and they were acting in that slightly drunk way that affects us all from time to time.
As we continued on our way, the darkness came down and Merril, who was sitting directly behind me became more drowsey.
We turned a sharp bend causing Jackie to lose her balance.She was still kneeling and facing the wrong way, and instinctively her arm shot out into my lap, and onto my groin area. I had until that moment not realised that my penis had swollen into a semi erection, and now my embarrassment was complete with Jackie totally aware of my condition.
"Oops. sorry, Steve" she said. "I lost my balance"
I glanced in the rear view mirror and saw that my wife was leaning back with her eyes closed, and had not noticed what had just happened.
"Naughty you" I said, and my hand slid up Jackie's bare leg under her shorts and onto the crotch of her panties.
