Mother's night visits

I knew my father was neglecting my mother 47 and she got depressed and her doctor put her on some medication to help her get over her depression. My father still too little notice of her and went away fishing. That night I was in my bed and then my door opened, and my mother came in, I turned on my light and she was totally naked. I was confused and shocked, more confused than shock, I think. She asked me would I be a good son and fuck her, my confusion disappeared, and shock took over. But my cock went rock hard and I finally came back to Earth you could say. Knowing my mother wouldn't ask me to do something unless it was important to her, I agreed, and we fucked and spent the night together. It wasn't just to help my mother; I'd already had a hard-on and there was a great deal of self-interest on my part as well. That whole weekend was spent fucking my mother and it wasn't just her asking me for sex, I asked as well. My father returned late Sunday evening and was gone before 7 in the morning and so I asked my mother for sex before going to the university, she agreed and fucked then showered together. I was home before my father and had sex again with my mother. This is how the days passed for about a month, my mother seen her doctor again and he took her off the medication as there had been side effects reported and the doctor to be cautious. I got home from university and gave my mother the now usual feel up and we went to my bed and fucked. Once the medication had passed thru her system. She still kept fucking me, albeit not as much as before. Then my father decided to ask for a divorce and I think he was surprised when she agreed straight away, no crying or fuss. A quick divorced followed, mother got the house, cash payment and alimony payments as well and my university fees paid and that was it. The first day my father had left the house for good, my mother moved my things into her bedroom. I still had my room she said for when I brought a girlfriend home and sleeping with her was icing on the cake. Still no girlfriend, but I do have a very willing mother.
