Visiting my Mother update

I'm Grant and last year I went to the East Coast to visit my mother Helen and starting sleeping with her. She then got a transfer to the west coast and sold her cottage and since has bought a house on the West Coast for us. She introduced me to Heidi and I started sleeping with her as well as Helen. After our first fuck, Heidi was worried she might get pregnant. But she didn't and I kept fucking her without protection and finally got her pregnant. That was in January and the baby girl is due in September, Heidi and I married in March and still live with Helen and we all sleep together still. Heidi's mother Jean 45 is divorced and I seduced her just after we met and she now also lives and sleeps with us. Heidi isn't letting me fuck her now she is in her last trimester, but I get sex from Helen and Jean. My mother Helen sister Rhonda 42 is coming for a visit when the baby is born and I'm going to see if I can get her into my bed, she has 2 grown children and both are in the military. She late husband Jarrod was a career man in the army and died in a training accident 4 years ago.
