Mom's late nights visit

I'm Gerald 28 live alone in my own home, I the youngest of 3 and the only male. My father Richard divorced my mother Hanna 53 5 years ago and married his P A. Hanna didn't take it very well and started to drink, but after the divorce was final she stopped drink and started to put her life back together. She had married at 18 already pregnant and hadn't had any career of her own. She sold the house she got as part of the settlement and downsized to smaller cottage. My sisters are both married and have their own children, I haven't found a wife yet. Then in January 2019 Hanna dropped by to visit me on a Saturday afternoon, I was doing some repairs to my house. It was run down when I bought it 2017 and I'm doing it up as time and money permit. All major work is complete and it just the small jobs left to do. Hanna visit was a surprise as I thought she was away visiting my sister Catherine. After a couple of hours she was leaving and offered to clean my house for me as it was a mess from repair work I had been doing. I hadn't cleaned much after finishing repairs, only my bedroom, bathroom, lounge and Kitchen were passable, the other rooms were a mess. I would be away for 2 days and I gave her a key, I had intended to do a quick clean and remove the rubbish leftover from the repairs and get a cleaning service to give the house a good clean. So on the Sunday I got rid of all the rubbish to give Hanna easy access to do the cleaning. Hanna came over on the Monday and started cleaning the house and finished it on the Tuesday. I got back early on the Wednesday and was amazed how good my home looked now it was cleaned. I rang Hanna thanked her, then just after 10 pm I was in bed and intending on going to sleep. I heard the front door open and then shut. Then there was someone in my bedroom doorway, I turned on my bedroom light and saw it was my mother Hanna. I asked her what was wrong and why she visiting so late. She said You said you owed me big time for cleaning your house and I came to collect. What do you want I asked, a good fucking was her reply and she dropped coat to the floor and was standing there totally naked. I was shocked at first and I always sleep naked and felt my cock harden and asked had she been drinking and she said no I'm so horny and need fucking. I threw aside my bedspread and told her to join me. She did and I fucked twice before fell asleep, in the morning she made me breakfast and then I went to work. Since then she comes over anytime she wants fucking and I make sure she is well fucked. I've also went and see her at her place several times and straight asked her for a fuck. She always agrees to have sex with me.
