Last week was my wife's birthday and we celebrated with a party. The run up to it was hectic and quite exhausting. However with everything in place we were ready to have a good time and entertain our guests. The night before she was out with some friends for a while and came back with a playful look in her eye. That she wore a short skirt not normal for a meeting with the girls suddenly intrigued me that she was up to something. She asked if I had been drinking but as that is very rare at home, I shook my head and she said would i like to take her for a little drive. Now the playful look, the skirt and her smile made sense and we were going into the evening sunset for a bit of flashing fun and who knows what else? Quickly into the car we drove towards the dual carriageway and then onto the motorway. The traffic was light and mostly artics roaming north and south but well scattered. I pulled her skirt up and saw her small panties complete with tell tale damp patch. I suggested it was warm enough for her not to need either and she smiled and said she hoped I might say that. I suggested naked would be even better. No sooner said than done and she sat naked next to me as we closed in on two artics. One indicated to pass the other and I pulled into the third lane to give our trucker a treat. She folded her clothes neatly and placed her panties on the dashboard top where the wagon driver would not miss either the panties or what they had been covering a few seconds before. As it was dusk I had my lights on and put the interior light on to illuminate a sexy cunt and body to the lucky guy. Oh yes, he saw all right and a blast of his air horns left no illusion that he might have been studying the road rather than my wife's trimmed cunt. She smiled up at him and got a further deafening blast as we pulled away, his lights flashing and indicators going on and off. I knew he was wanting us to pull off at the next junction but knowing the roads well, this was not a good place to leave, no convenient lay byes. We moved on with a giggle at the sexy scene towards a place where we expected an interested party might see a naked woman being fucked. We flashed five other wagons and got similar blasts or blinding light flashes and Liz was lapping up the attention. Eventually we pulled away from the busy roads onto a single track road which led to some woods we know and a lake where fishermen have been treated to a sexy display. It was one of those nights where the sky refuses to go dark. An weird yellowy green light through the trees as we arrived. Two cars were parked up facing the water. Liz asked me to check the surroundings were free of lady anglers or younger people who might be shocked by seeing a naked woman at the water's edge. I stepped out of the car and walked to the edge of the lake but saw nobody at first, the camouflage obviously working so I moved around then saw a light on the left of me. A sole angler baiting up. His light extinguished and a distant plop of his tackle (fishing tackle) as he sought his quarry. I heard a car door close but was a little out of sight of our car so moved back towards it then I saw Liz standing outside the car still naked talking to a man. I stood stock still and listened intently to the conversation. The guy asked her what she was 'doing there?' 'Looking for fun' she answered. 'Are you alone?' 'Well I am right now' 'What fun are you wanting?' 'Maybe a cock if you are clean' I was now in awe of what she was doing, just rubbing his cock over his trousers and getting both of them turned on 'Can I touch?' he asked. 'Yes but get your cock out first' He obliged and she said it looked good enough to eat, and proceeded to take it in her mouth. His groan of pleasure had me a bit jealous knowing how good she was but it was a major bonus for me to know she was going to be fucked. Being an avid watcher I was happy with this and she took him to a climax just that bit too soon. He shot his come down her throat and within a minute had zipped up and disappeared. Frustrating but they are sometimes as quick as Usain Bolt. We decided that time was getting on and we were both working next day. She dressed where they angler may have seen her but got no response so went back home a tad disappointed but on reflection a lot of harmless fun for us
