After her Divorce

My mother Joanna 51 got ill and recovered slowly, my father Donald decided she wasn't worth his time. So he divorced her in 2019 and moved interstate, I was still living at home and I stayed with Joanne. The divorced had hurt her and she went a little strange, but I put it down to her illness and the strain of the divorce. She seemed to be improving and then the pandemic started in 2020. So we were isolating together, I'm Colin 27 youngest of 3 and my siblings were married and building their families on the other coast. One night I was in bed reading and my door opened and Joanne walked in and dropped her robe onto the floor and was totally naked. She got into bed with me and asked me to fuck her, I was shocked at first. But with her playing with my cock it went hard and so I fucked her and she spent the night in my bed with me. I've didn't have a girlfriend at the time, but dated fairly regularly and had some success sex wise with my dates. But fucking my mother was at first shocking but very enjoyable and when she asked me to share her bed I agreed. Having regular sex with me seemed to satisfy something and she returned mostly to her old self. Except in the past I wasn't fucking her, I was attending the local university and only the lockdown stopped me attending. When everything got back to near normal, I was still regularly fucking Joanne. I was enjoying the regular sex with her and she had come to terms with her divorce. Last year I finished university and got a job offer interstate and was going to knock it back as I didn't to Joanne alone. She told to take the job and she would sell up and move with me to allow me to start my chosen career. She got a house close to my workplace and we carried on as before. She met Barbara 52 widow and her daughter April 23 (only child)and they became close friends. So close she invited Barbara to join us bed together, which shocked me at first, Barbara is more cuddly then Joanne. But still a great fuck, then I was told Barbara and April would moving in with us. Joanne asked me straight out about marrying April, I had hardly met her and now I was asked to marry her. April quiet and timid wears glasses, good figure and rack looks like Bernadette in big bang theory only a brunette. I wasn't sure and said what does she think and was told she'll do what Barbara tells her too. To add a spice she added you'll still be able to fuck Barbara and me. I was still thinking and she pressed for an answer, I just nodded and Barbara and Joanne started planning my wedding. About 3 days later I got April alone and asked her what she thought of us marrying and she said mommy said I should and I do what mommy says. But I was thinking I should call the whole thing off, but Joanne had April make a foursome and I not only took her virginity, I got her pregnant as well. Not that we knew for a time after that night. I also found out quickly after my first fuck of April, she would let me fuck her anytime I wanted too. I finally decided to marry her and 3 weeks later she was confirmed as pregnant and we had our son in April this year. I quite like being married to April and am doing my best to make her happy. April is very happy being a mother, Neither she, nor Barbara or Joanne work and I'm can get sex from any or all whenever I want.
