My wife and I got married right after I graduated and we moved to the city where my job was. She had one more year of college and went back to finish. We were almost 1000 miles apart and started having phone sex. One night the subject of it not being as good as real sex came up and my wife said that a solution to that would be if she got a boyfriend and she called me while they were having sex. I agreed that it would be better and said that the next time she could listen to me having sex with another woman.
So the next night, she didn't wait very long and I think that she already had someone in mind, she called me and I listened to her being fucked and the bed hitting the wall for about twenty minutes. I timed my coming to when my wife and her boyfriend were coming. We were still on the phone when he left and my wife said that I could listen to her having sex most every night. So for a school year I listened to my wife having sex four or five times a week. I found that I was only horny on the days that my wife was having sex and that I didn't want to have sex with any other woman. I would picture in my mind my wife lying on her back with another man between her legs or her being fucked doggy style and have a great orgasm. My wife had eight lovers during that nine months and I did not have any. We got together during school vacations and I noticed that my formerly tight wife was now much looser between her legs.
