The son would just prefer mature women like her mother

sex with my son was something that happened only once, my husband was traveling and we felt that we were both alone, so one night we enjoyed a fuck. But now that I am reviewing the search history of the computer, I realized that my son sees only porn made to incest. I said it only does this excite. And while I was flattered, I was really worried. I did not want my son to be obsessed with my pussy. That’s why I’ve allowed to fuck me once again, only to remove the desire to have sex with a mature girl. We have done nothing special, just a simple fuck and ejaculation inside of me.
