My wife and I spiced up our love life several years ago by having threesomes with another guy involved. All of the meetings went extremely well as she got off on it so much. One night, we invited over a male/female couple. That was a night of pure pleasure! I got to watch the couple have their way with my wife over and over. They both seduced her and she had more pleasure that one night than she has had in a year. I didn't join in until much later into the evening, as I was enjoying watching the two of them have their way with my wife. I finally joined in and not only gave my wife oral, but got to do her in front of another couple. That was a huge turn on for me. It was indeed an extremely hot, fun night.
