Fun with my old Neighbor

Last year my divorce was final, a bitter divorce and I'm glad it's over. No children and so a one off payment and nothing else to pay. I moved to another state to restart my life, I can work from anywhere and so I chose a small country town off the beaten track. I'm Andrew 32 and settled into my new place in February. Only one close neighbor Catherine 62 widow and no close relatives living close by. I didn't interact with anyone for the first couple of weeks keeping to myself, Then in March I was cleaning a rubber mat in my backyard and Catherine introduced herself to me. She is nice looking and fit for her age and after that we chatted often. Finally at the end March I was going to the city for a break and to get somethings, Catherine asked me would I mind her coming along with me. No, but I'm staying several days and at a motel I replied, Oh I don't think I could afford a motel room she answered. I then said well you could stay in my room if you don't sharing a room. I never expected her to agree to that, but she did and so we headed off to the city together. On arrival in the city we checked in and put our things in the room, there were 2 beds in the room. Then headed off to do some of the things we had came to do. Returning to the room about 5 and Catherine went to shower and then I did and we went to the local diner for a meal then back to the room and a early night. The next day was busy and we travelled about together and I still had most of stuff done by that evening. We watched T V and then to sleep, the next morning we finished everything and had a look around the city, then dinner at diner and then to a movie together. Returning to our room, Catherine said she would shower before bed and I joking asked did she want me to wash her back with a big grin on my face. She smiled back me and headed to the bathroom, then she turned and said okay I game with a big grin on her face. Not sure whether or not she was serious, I didn't move at first. But she told not to be shy and I got up and went with her into the bathroom. We showered together and she got into her bed after and I got into mine, I looked at her and she asked me to join her in her bed. I did and I fucked her twice and again in the morning, on our way home I turn off on a dirt road and pulled up out of sight of the highway and asked her was she willing to have another on the back seat. She said okay why not and we fucked again and then headed back to our homes. She stayed the night with me and regularly stays overnight since. She calls our relationship friends with benefits and I really enjoy her benefits.
