I listened to it all once when my wife's cellphone somehow dialed the house during her tryst. I didn't know what was going on at first, but then I heard her say, "Why are you looking at me like that?" I couldn't hear his side of the conversation clearly, but she was giggling at what he was saying, then there was, "What if someone comes in?" She was at work at the restaurant, and it was late, end of shift, and they would have been closed. She said, "Wait, I'll take it off," then there was quiet except for her moaning. Then there was a loud moan and a man's voice saying, "Damn yiur pussy is hot." He was giving it to her pretty good for several minutes then the phone went dead. She came home about 45 minutes later and went straight to bed. When I joined her, she was naked and wanted to fuck, but wouldn't let me lick her pussy. That was one of the hottest fuck sessions we ever had, and I knew I was a proxy fuck. Never told her about it at the time, but I met the guy at her Christmas party several months later. It was pretty obvious he was the one from the way they were looking at each other.
