My Grandma's Diary

I'm Frank 23 work as a mechanic and a total smartass, I've had relationships that usually don't last long. My family is fairly well off and all my siblings have been thru university and done well. I wasn't a good student and barely got thru high school and so I trained as a mechanic as I liked cars. I'm my families greatest disappointment career wise, but they hope I will improve overtime. My grandpa Patrick died 2018 and that left grandma Kathleen 65 alone and with the downsizing of my parents to live closer to their first grandchild Patrick, I ended up living with Kathleen as the only relative still living locally. I was okay with that as she didn't try and restricted my activities much at all, I can come and go as I want. Just no parties at her place, when she went to visit her first great grand child Patrick I was alone for 5 days. With all of my friends also away it was a little boring. I sat watching TV after work, but nothing kept my interest for long. After a time I started looking around for something to interest me, gran's books weren't of interest to me. Then I came across several old Diaries of my gran's. I had a look but they were also boring as well, until I found her current diary and found it a lot more interesting. First I should tell you something about Kathleen, she a very conservative religious woman if you went by how she present herself to everyone. But reading her latest diary I found she to be a very randy woman who missed getting fucked by Patrick a great deal and I now knew why they had 6 children of their own. In her diary she writes of having to masturbate herself regularly and getting horny around any male not fully dressed. Like the entry about the plumbers taking off their shirts while digging a small trench next door to replace a water pipe. Then having to go to her bed and masturbate. I thought I would have loved to catch her masturbating, then my devious brain started to get an idea. I wondered what would happen if I was around her in just my swimsuit or just shirtless. I finished her diary and returned it to its place. Then several days later I got home from work and Kathleen was home. I was dirty from work and went straight to shower and change out of my work clothes. I hadn't thought of what her diary had said, but while showering I did and so I only put on pants no shirt and then welcomed Kathleen home with a kiss on her cheek and a cuddle. I expected her to disappear into her bedroom, but she didn't. Then later I wasn't in the mood to watch TV and asked Kathleen would she like to catch a movie with me and we could grab a snack for dinner while out. Yes she would join me for a movie, but no a snack. Saying your shouldn't rush your meals, so we went out and had a meal at restaurant then then on to the movie. We both enjoyed the movie and when we got home went to our beds. I was a little disappointed that she hadn't reacted to me being half dressed. But that was just my first try, more followed and I was about to give up and forget about it. When she asked what I had planned for the upcoming long weekend, I hadn't anything planned and said so. Good I need to go to Patrick's old fishing cabin and check on it and was wondering if you would come along she told me. I would be happy too I said and that meant we would be away from almost everyone as there wasn't any other cabins close by. I arranged to finish early so we could get on the road before the rush. It worked great me and everyone else who were going away for the long weekend had the same Idea. After an hour longer than it would take normally we arrived, there were some branches laying around near the cabin, but no damage I could see. While Kathleen checked inside I removed the branches and gave a tidy up outside. We had cold children and salad from home dinner that night so I decided to have a swim before dinner. I went into the lake and swam about and Kathleen sat on the shore reading. After I finished I stood near her drying myself. After drying my hair I noticed she was looking at me intently and I thought maybe I've finally peaked her interest. But it didn't last long and then we walked back to the cabin and had dinner. After a couple of hours with her reading still and me playing games on my phone. I decided to go to bed, I went to the spare bed and jumped into it and there was a loud cracking noise. The old wooden slats had broken, Kathleen even heard the noise and came to see what had happened. With the bed broken she said I would have to share double bed and we would see what could be done about my bed in the morning. I was only wearing shorts and was going to put on a T shirt, but decided not to. I got into bed beside her and waited awhile and then went to sleep. Later I heard a soft moaning coming from Kathleen and on turning towards he saw she was masturbating herself, with one hand rubbing her breasts and the other her vagina. I got an instant hard-on, Kathleen looked really horny. I hadn't expect to get aroused myself, now that I was a lust filled idea came upon me. Maybe she would let me fuck her, but I couldn't just ask her for a fuck. I decided just to chance it and started to feel her up and see what happens. At first she didn't realize I was touching her, but she soon did and was shocked by my actions. I just said I got carried away and hoped she might want me to help her. By help you mean sex don't you she asked, maybe I responded or just helping you by rubbing you to help get you off. I then started to think I was in big trouble and rolled back onto my back and my cock formed a tent in the covers. Which she saw at once, then to my great surprise she removed the covers and turned on the light and on seeing my hard cock. Without saying anything more she got my cock out of my shorts and just looked at it. Then she started to stroke it and then told me to fuck her. I done as she said and fucked her as hard as I could. But I didn't last very long, but wasn't upset by that she went down on me getting hard again and again fucked her, She really good for an old gal and I was totally spent after the sex. Next morning I awoke and I was getting out of the bed and she awoke and asked me would I give her another fucking. So I did and I soon found out, Kathleen loves to fuck. We fucked the rest of our stay and she had me share her bed at home, unless we had visitors. Now I'm still living with Kathleen and still date girls and yet to find a girlfriend. I've had more sex from Kathleen then I had before I started fucking her.
