Wiped and loving it

My wife is my best friend and the love of my life. We got married as soon as we were out of school and our son was born 9 mouth later. Some history we grew up next to each other our bedroom windows were side by side. In the summer we would talk all night long. We told each other everything until we were about 12 then things changed. I don't remember what happened or what I did but she stopped talking to me and closed her window and blinds. My mother asked what happened because Julie's mother stopped talking to her. I said I didn't know? Any way It was about 2 months later when I noticed that her window was open a little bit and when I went over to see their was a note inside my window on the floor. Which said Help I need you to watch so you can be witness to what going on. I really didn't know what to do? Later on I had my lite off waiting for her lite came on when it did I was about to say something when I realized that her father was with her and what he was doing to her I couldn't believe so I pulled out my phone and filmed it. After I went and showed it to my mother and after she realized what was going on she called the police and had Julie's father arrested. Things went back to the way they were. Now all grown up with a son Things are good. Until one night after making love she asked me what it felt like watching her and her father. I didn't know what to say about it and that's when she said that it really turned her on knowing I was watching her getting fucked. She then asked me how I would feel about watching her get fucked by someone else. I said fuck no
That's when she grabbed my dick and asked me why I was so fucking hard. We fucked again and I came so hard and much more then I did the first time that night she said that she even came. From that time she kept saying what about him pointing out different guys we would see in public. Then without anyone seeing she would feel to see if my dick was hard. Then she started asking me how I would like to fuck her pussie full of his cum. To tell you the truth our sex life was pretty good. This one day when we were at the mall when she said ho my god look over there that black guy sitting on the bench with the shorts his dick is hanging out. She said sit down here. She then put her bags in my lap and grabbed my dick finding it getting hard she says you have to let me fuck him. Before I could say anything she was waving to him and left me sitting there as she walked over saying hi and pointing to me I could see as she sat down and started playing with his dick and giving him a kiss.
