When I was young I would drive the car deep into the woods and have sex for a very long time but a couple of times I got the car stuck and spent ages getting it out after a big session. Once I got the front wheels down a ditch and another time I got the rear axle stuck on a tree stump with both driving wheels off the ground!
Once on the side of a country road with the girl naked in the dark I could see a cop creeping up on us and as he arrived at the side of the car I pointed a flashlight straight in his face and said "Yes! What can I do for you?" He jumped and said "Oh!" and "just don't make too much noise when you leave, sir". The girl said she recognised him as a neighbour!
