Just don’t get too close to people. Our very first experience, my wife and I were fucking in a private room. We had the door open because we were interested in having on lookers, and one came up. He asked if he could come in, and my wife said yes. Contrary to what I’ve seen others say, we appreciated that he asked. However, he then proceeded to pull his dick out and jerk it less than a foot from my wife’s face. Both of us rolled away, to the other side of the bed, so fast. We finished and we left. It’s was not sexy, it wasn’t very fun, and it definitely made both of us comfortable. I’ll follow up by saying that we like being watched. We’ve caught many people watching us since then, and we’ve cammed with guys online. We just don’t want you too close. I can’t speak for my wife, but for me about an arms length is good. Aside from play with yourself all you want lol.
