Grandmother

My mother's mother 59 had been kept sheltered by her husband rarely going anywhere while he was alive. He controlled everything in her life, my mother on the other hand was married off quickly at 18 never went to college. But my father wasn't as my mother's father thought. He was more liberal in his mindset, so my mother had freedom her mother didn't. In late 2023 my grandfather was playing golf and had a stroke, he died enroute to the hospital. After the funeral, my mother asked me to live with her mother while attended college nearby. It wasn't a demand, but I felt she really wanted me to agree, so I (then 20) did. As the youngest of 3, my twin sisters were going to another college further away. I moved in and soon found it quite shocking, as I hadn't realized how out of touch my gran was with the outside world. She still wrote out a grocery list that my grandfather would've got. My mother was with her at first, but I was to allow her to return home to help my father in their business. I'm pretty relaxed in my outlook and date sometimes, not much success, but not a virgin either. My gran would let me do whatever I wanted, I soon realized. That's the way she was conditioned by my late grandfather. She a great looking woman for her age, I found that out by accident. When I walked in on her totally naked, I quickly left and was shocked to when I realized I'd a boner as a result. My gran had reacted at all which also somewhat shocked me. But it passed then I was asked to stay with my gran during my break from college by my mother. I'd no girlfriend at the time and agreed as I would have more chances of fun with the city then back home in a smaller town. No real plans, given an extra allowance to make my stay better. One day nothing planned and a shopping list to fulfill, I decided to take my gran shopping with me. I expected her to resist she didn't, just went along with my wishes. It was an eye opener to her how everything had changed, after everything was put away, I decided to take her to a movie. She agreed no resistance again, we enjoyed ourselves and so I decided I would take her out more often. Then on a rainy Saturday I'd been working outside unblocking a drain. Was soaked and on entering I striped off the wet clothes, using a towel to dry off. I was about to go to my room to dress, when my gran entered the laundry. She got an eyeful that time, no reaction from her at all. My mind thought back to me seeing her naked and I got an erection. I was shocked by it happening, still no reaction from my gran. She asked me did I need any help, I said yes if you want too. Expecting her to wash my wet clothes I think, but instead she started stroking my hard cock. Saying my grandfather had gotten her to do it for him often, I was a little unsteady, I think it was the shock of her masturbating. She suggested I lay on my bed, and she would get me off. Once on my bed she restarted stroking my cock again, I'd to ask why my grandfather didn't just have sex with her instead of getting masturbated. His heart was her response; I found myself saying I didn't have heart problems. Not expecting anything I think, mainly because I was shocked when stopped stroking my cock and then undressed completely. But a willing woman is a willing woman grandmother or not, so I fucked her. As the saying goes once you start it can be hard to stop, regular sex became normal between us. I still date and get lucky sometimes, but a willing gran makes up for when I'm not.
