That's similar to what happened with my wife. I was shooting pool, my wife was at the bar sitting next to an older gentleman. I just glanced at them but did not interfere. Eventually I went over and said hi. He looked at me and I gave him the ok look. He continued flirting with my wife. They began touching each other's thighs. I smiled at him and he knew to continue. Eventually he said he was to call for a taxi and I offered to give him a ride with my wife and I. They sit in the backseat together making out. We get back to his place my wife was his for the next 2 hours while watched. My fantasy happened that night.
