Recently I've started fucking my mother

My father Harold 52 told my mother Janet 46 that he wanted a divorce and after then left the house and hasn't returned. Janet was really upset by Harold wanting the divorce that she started drinking a lot. The divorce is proceeding and Harold has given the house to Janet and made offer about money he is willing to pay her. I on the other hand as the only child haven't been mentioned by Harold. I'm Harold junior 21 and work at a local factory, I'm always been a big disappointment to Harold. Not smart enough for university like he was, but I'm couldn't get interested in studying. But can take a car engine apart and put it back together, as well as making anything I want in metal or timber. Which I sell and make good money when I sell them. But I can't make things quick enough to make a living by just doing that. Janet came home from on the day Harold left and found Janet drunk and over the following days she would be drunk when I got home. Then I decided she had to stop drinking and got rid of all the alcohol in the house and hid her purse. She could buy anymore for a short time, she wasn't happy about me forcing her to stop drinking. That what she said at first, but she calmed down and started to return to her normal self. She said it had been a total shock to her that Harold wanted a divorce, I told her she didn't need him. She said that she missed cuddling up to him in bed, I said you can cuddle to me if you want. She shook her head saying I more than cuddling. I replied I know you mean sex and I will provide that if you want. That was a big shock to her and after minute or two she said I' your mother you can't fuck me its incest. I answered why can't I your passed having babies and it would be just between us nobody else would need to know. After a bit more talking I walked over and gave her a cuddle and kissed her on her cheek. Nothing was said for a while, then I asked her to go to the movies and have dinner out for change. She agreed I think because she felt a bit awkward over the sex talk we had before. We a meal out and then saw a movie together and on getting home I kissed her again. I was going to go to my bed, but Janet asked me to sleep in her bed. I looked at her and she added not for sex just sleep. I smiled and agreed, I went and put on my PJ's and went to her room and got into her bed, she was in her bathroom and came out in her nightgown and joined me un the bed. I kissed her again and she turned off the light. I fell asleep and awoke several hours later wanting to pee and went to her bathroom. On my return I got back into bed with her and cuddled up to her, she was still asleep. I started to feel her up a bit and then she turned over to face me. I was expecting her to be a little cross, but her hand went straight for my cock and started to play with it and it went hard straight away. I moved my hand down to her vagina and once under her nightgown I started to finger her. This was all that it seemed was going to happen, but I asked her to let me fuck her and she said okay. I fucked her again in the morning and regularly over the next week. Then I was told to stay home by factory as everyone had to isolate. I was home isolating for 4 weeks, passing the time fucking my mother Janet. Then our factory started up again and I returned to work, but I'm still fucking Janet and sleep with her every night. I haven't seen or heard from father since he left us.
