I went out for a drive one afternoon, the weather was fantastic I had the top down the wind was blowing through my short hair life was good, I came across this wooded area with a car park so I pulled over to stretch my legs, there where a couple of cars parked and as I looked through the trees I could see a couple semi naked getting up to some naughty now being the curious women that I am I went over to say hello, the couple where a bit taken aback at first but I introduced myself and tried to put them at ease, well what happened next was simply amazing Paul and Vivian asked if I would like to join in, boy would I, I walked over to where they where lying and as I did I striped down to my bra and panties, we had an amazing sex session which lasted for hours.
