Making mom happy

My father Martin left us last year and doesn't help us out in any way. My mother Glenda 36 has 3 children to take care if you count me. I'm Ross 18 and I work as a plumbers assistant and live with Glenda and my 2 younger siblings, she worked spot jobs when they were available. Glenda is always complaining about how hard it is to provide for the family. She was getting drunk on a regular basis, when she was drunk she said if she was pregnant she could get money from the government and that would solve a lot of her problems. I could say Glenda is totally gorgeous, but truth be told she average looking and build. But she still has a great figure and early last month my siblings were in bed asleep and Glenda was passed out drunk again. So I took her to her bed and while putting her to bed, I recalled her saying getting pregnant would better for her and the family. So I pushed aside her panties and fucked her leaving my seed inside her. Next day she didn't know she had been fucked and went looking for spot work and with the coronavirus job are few and far between. She got a couple hours only and on her way home picked a food hamper from a charity site. I also got food from a charity on my way home as I was only working 2 or 3 days a week at the time. On arriving home Glenda had dinner ready and we all ate and after she hit the bottle again. As had become normal now I put her to bed. I went and made sure my siblings were in bed asleep and and then headed for my bed and while changing for bed. I thought about the previous night and got a hard-on and so totally naked I went to see Glenda was sound asleep still and again I fucked her and left my seed inside her. This was how it was for 5 nights, then Glenda ran out of alcohol and was sober for several nights. I was thinking of getting her a bottle and fucking her again. But I didn't enough money as I had to pay our rent, unable to do anything for myself. I sat and watch TV with the family and after my sibling had gone to bed I was thinking of turning in myself with no work the next day. I was going to go and see I could another food hamper for us. Glenda was a little restless and as I got up to go to my bed, she asked me would wash her back for her. I've done this in the past and she would go and get ready and call me in to wash her back. She would wrap herself in a sheet leaving her back exposed and I would wash it and then leave her to shower. When she called me I entered the bathroom and she was totally naked and told me to undress and join her in the shower. I did as requested and as I washed her back, she told me that she was really horny and wanted to know if I would help her out by fucking her. My cock was hard as soon as I had entered the shower with her and said I would gladly fuck and we had sex in the shower. After I felt ready for another fuck and asked her could we do it again and she looked at me for a moment and nodded and without dressing we went to her bed this I time I left my sperm inside her and she wasn't really happy about that. But it had been done and it was too late to change it. I said well you said you would be better off if you were pregnant and she smiled saying they might not think me being pregnant to my son is proper thing for a mother. Don't tell them who the father is and if they press you for a name say he called himself Donald Trump and I was too drunk to care at the time. She laughed and said I could never be that drunk.
