M [Corno] What triggered everythin

When I was dating my wife, I asked her to masturbate me because I didn’t want to have sex, so she started making comments about my penis being small after I came, and I said it was mean. She said she wasn’t being mean and that it was the truth, so I kept thinking about it. Then she started being meaner, and I said it turned me on a lot, so she said, “Can I be really mean today?” and I said I’d love that. Then she started telling me that she had already slept with several guys and asked, “How much detail do you want me to give you?” and I said, “You choose and be as mean as you want.” Then she started picking up her cell phone, came over and spat on my dick and said, “You know my friend that you like so much, before I met you I used to have sex with him,” so I froze and said, “Is that all?” Then she started, “When he had sex with me, I felt so hot because he was so strong, I came a lot on his dick and he was the first guy I had anal sex with.” I kept thinking about it because we had never had anal sex. She started talking about how big and delicious his cock was, how good it felt to masturbate him. Finally, she showed me the messages she had exchanged with him. The thing is, she didn’t even masturbate me, and I was leaking a lot, so she said, “Masturbate thinking about how much I came and still come thinking about that big white cock.”
