Ramblers Eye View

Since I first lost my virginity at the age of seventeen to a forty six year old in a country park, I've always enjoyed having sex with older men outdoors.
So last month meeting a guy I've had sex with a lot recently, a fifty three year old, we were in the woods by the reservoir with him fucking my arsehole from behind.
I'd literally just orgasmed when we both heard someone say "Kelly, is that you".
I was about to pull off my older friends cock, but he was reaching his orgasm and he came hard up my bum. Thats when we both turned to see a group of older ramblers watching us from only twenty feet away. And one of the ramblers was Mike my neighbour.
It was he who had spoken and was staring at my arse, which by then was dripping cum onto the ground.
Some of the group walked away, but I saw my neighbour hold his cock bulge and definitely gave his dick a few strokes through his trousers.
He eventually followed his group but not before he winked at me.
Mike is in his sixties I'd guess, married and definitely as of the last few weeks flirting with me.
He told me a few days ago his wife will be away for a few days shortly, and wondered if I'd like to take a private walk, as he put it.
I'm really tempted to, but I'm not sure I should fuck a neighbour.
