Hottest thing your wife has said during sex

After our first swap with a couple my wife and and her partner fit together easily, we were playing when they started. My wife was a little loud with moaning and breathing. The first time any of us had ever had full tilt sex with another in front of our spouse. We both were so infatuated with watching them that we didn’t complete the deed. My wife was bothered that I didn’t get the same thing she did. When we got home she talked me through pretending that she was the other woman. I was calling her the other woman name and talking really dirty talk for us at that time. The way she was totally into being her for me is the most surprising unexpected thing ever. We used that many times after, for her too.
