My Grandma caught Me

I'm Scott 27 and I live close to my grandma Lois 62 widow. Anyway I've a thing for mature women, I like fucking them. It started when I started work out of state and living in a boarding house and a mature boarder came home drunk late one night. I had not long gotten back myself and had just finished showering and was heading back to my room in my shorts. I hadn't thought anyone else was up and so I headed for my room, then I ran into Joan 57 and she was drunk and horny and she grabbed my cock and straight out asked me to fuck her so I did. It was the start of regular sex with her till I returned home and I had taken a liking to fucking mature women because of fucking Joan. Mainly because they weren't as picky as girls my own age, also I soon was able to pick out mature women who would be willing bed partners. I bought a small house and done it up over time. I had affairs with mature women I met, they were willing and it usually last a few weeks and then we parted. I met Harriet 59 and had been fucking her on and off, usually when her husband Donald was away. So I was home fucking Harriet and Lois came over to bring me a cake, as she did from time to time. She had her own key and let herself in and caught me fucking Harriet. It was a little awkward, but after I went and seen Lois at her home. She wasn't concerned that I was fucking Harriet, as she didn't know Harriet. But she asked why I was with a mature woman than one closer to my own age. I said one reason they can't get pregnant and the other is less hassle. She smiled and said you should find yourself a wife at your age. I said I'm looking and no luck as yet, all was good between us as there wasn't anything wrong as far as Lois knew. She didn't know Harriet was married and thought her a widow like herself. I continued with Harriet for another month or so. But Donald got a job interstate and she moved away, I hadn't anybody else at the time. So was on the look out for another sexual partner, Lois asked had I found a girlfriend yet and I said no. She then asked was I still seeing Harriet and I said no she moved away. Anybody else she asked, no I'm seeing nobody and then she asked would I do her a great favor. Anything I answered, she then asked me to sleep with her as she had gotten very horny after catching me and Harriet bed together. Playing with herself wasn't satisfying her anymore, especially when I and her been together before. I was shocked and slow to respond and she added she had to ask for peace of mind. I recovered my composer and decided why not, she was willing and I liked fucking mature women. So I agreed and we went to her bed and fucked, it was a little awkward at first. But it passed and we became regular lovers, she was willing to drain my balls anytime I asked her. Then the rent on her place was increased and I asked her to live with me and she agreed. She gives me sex regularly and tells me to find a good girl to marry. No luck as yet.
