The wife and I find that having sex in a public place with a chance of getting caught to be both stimulating and exciting, it definitely adds a thrill to the act . What are your thoughts and where have you done it.
There's been several but I think the most memorable was a well know Northern Indiana state park. We were hiking a trail and decided to duck into the woods. We spread out a blanket and went at it. Hearing other hikers on the trail made it even more exciting. After we both were well satisfied, we were just lying there naked when a young deer walked right up to us.
