I didn't know I was eating her freshly fucked

Shortly after we started hotwifing, My wife and I got home from a party and as I was in the mood for sex, she and I were kissing and swapping tongue for a while when I went down on her. she kept trying to keep me from going down on her. I was real insistent and after several failed attempts, I finally got my tongue into her extremely wet pussy. I was feeling very good about myself since I thought I had made her that excited to be that wet. As I ate her she got very into it and she was pulling my head into her crotch. I was really enjoying her reaction and when we finished, she was shoving her tongue down my throat and crawling all over me. She deep throated me and swallowed my come. She never does this on a regular basis, but she was so turned on. After nodding off for a while, I awoke to her staring at me and then she kissed me and said She was worried I might be mad at her. I asked her why and she said promise you won't be mad. I agreed and then she said remember how you always wanted me to have sex with another guy. I said yes as I felt my cock getting hard. She said she had been thinking about it for a long time and finally thought it might be fun but still couldn't figure out why it would be fun for me. I said trust me it would and pulled her hand to my crotch. She felt my erection and said good, cause she let the young guy down the street fuck her at the party last night. I said you mean I ate his sperm?
She said I thought you knew. I told her I was drunk, but don't remember him even being around her that much. She said she told me she was going to share a joint with him and when she didn't come back for an hour she thought I knew and agreed since I didn't come looking for her. I asked her lots of questions and she said are you still hard? I told her yes. She said good let's fuck again. He was 18 and a really good looking young man. She kept getting hotter and hotter, and we ended up kissing and sucking on each other again. We eventually fucked again and she said she wanted to screw him again. I told her yeah, I wanted to watch but she said she would feel funny doing another guy in front of me, especially a neighbor. I asked if she would ever consider it. she said maybe if it was someone we didn't know. I then told her to call him. she had him come over and said walk down the street and when he saw me drive off come around back and she would let him in. So he did and they got into the spa and screwed several times and she said for me to call her around 11:00 PM and that would be a signal that I was coming home. I arrived to see him walking down the sidewalk. I walked in and she was laying on the couch waiting naked for me to eat her saying oh please eat me that was so good last night.
We have continue this life style for many years and I love it so much.
