I am married to an imaginary girl

4 years ago one morning I fantasied that I meet a random girl on the street. We get to know to each other and we realize that we are born on the same date. We thought that we might be separated twins. She invited me at her home the other day so we can talk more. Then we celebrated our birthday together. Then we took a DNA test and of course it turned out that we aren't even related. We realized that we have many things in common and not just our birthday. We both love music, we suffer from the same problem and we are both interested in sex. She told me that she has few friends, have trouble communicating with people and never had a boyfriend just like I do. I told her that I have fallen in love with her and I want her to be the mother of my children and then she told me her big secret. She told me that she has uterus malformation and she was told that she can't have children. She didn't even have periods. I was saddened by this but I told her that I will love her no matter of that because she was the person that I dreamed to encounter. She started crying and hugged me. We decided to have sex next week. First time for both. We did it. I came to her home and we of course before we wanted to do some foreplay. I pulled down her black leggings and underwear and started to sniff and lick her asshole. She liked it and said that she wanted to than me for that with a blowjob. I let her to do so. I was too horny because that never happened to me, couldn't last long and I accidentally came in her mouth. I apologized but she told me that it's not a problem and she liked the taste of my cum and swallowed it. Then I said that one orgasm doesn't mean that it's all over for today and I will fuck her. Of course after some time I pulled down her leggings on the front this time, took them off from her and I started licking her pussy. We went completely naked then and I fucked her. After about 7 minutes I came again this time in her pussy. I did it knowing that she can never get pregnant. That was my first fantasy from one morning. I was fascinated by this fantasy so much that I decide that this will be from now on my imaginary girlfriend. After the first time we started having regular sex sessions. Once every week. Since April 2018 we started going out together. In October 2018 we started living together and in June 2019 we married. We started having sex more often - every day. And up to this day we have sex, we live together and we go out together. In reality I am alone but I am imagining that she is with me.
