My Aunt wanted me to get her Pregnant update

Last my aunt Paula asked me to get her pregnant as the sperm from her late husband Richard was lost in an accident that caused fire at the clinic. I agreed and after sleeping with Paula over several cycles he got pregnant and she had a daughter Mary Jane after her great grandmother. I'm still seeing Paula on a regular basis and sleep with her regularly. In March I was injured in a training exercise and that ended my military career. I moved in with Paula after leaving the hospital and when I was fully recovered I left and have got my own place since. Paula wanted to try for another child and I have agreed to help, I also have a girlfriend called Tracey 22 the daughter of my employer and she knows about me seeing Paula and Mary Jane regularly. But not that I'm the father, she thinks that I'm helping my aunt with things around her home and has come with me several times and she gets on well with Paula.
