Sitting in my car at a local spot known for dogging one day and I got lucky.

A couple in a small truck pulled up and got out. She was wearing a short black skirt, boots and black tights. He changed his shoes for boots as it was muddy, she looked at me and smiled. They set off up the path and I followed. He put his hand on her arse and hiked the skirt revealing that the tights were in fact hold-ups. They kept looking around and smiling. I caught up with them and we started talking together.

He said they'd stop at a seat further up and I asked if I could join them. They said yes. We reached the seat. She stood and leaned her hands on the seat and he lifted her skirt to waist height. No knickers! I was delighted and hard.

He got his big cock out and was straight in to her cunt from behind and she lifted her tits out from her top. She said get your cock out and wank if you like...

To be continued if anyone wants to hear the rest.
