My girlfriend and I recently had the chance to take a train while travelling. As soon as we were shown our cabin we both had the same idea. Almost immediately we tok off our clothes and stayed that way to feel how it is to be fully nude with people walking right outside the door. We took lots of pictures and then couldn't wait any longer. The sex was intense! She was soaked by the time I entered her and hearing people's voices and even feeling them bump the door at times as they passed by was a huge turn on. As she came she moaned loudly and it got quiet outside the door for a minute. We will be doing that again I assure you all!
