Helping my Mother

I won't go into a long history of how it started, enough to say my father divorced my mother. She went to pieces, and it was up to me to put her back together. But we were left fairly well off by the divorce as my father wanted a quick divorce and our lawyer used it against him. My mother started drinking and would be passed out when I got home from university. Takeout was our go to meal arrangement, and it was me who had to get everything needed. One day I came home from university a bit aroused after watching the girls do track training in their skimpy track kit. My mother was out to it as was now normal and still in her babydoll PJ's. Which didn't leave much to the imagination. So, being horny and her not aware of anything, I fucked her. After I had finished, I ordered our dinner and took my mother to shower her. Which also help wake her up, as usual she wasn't fully aware of much and after dinner. She would go to her bed, but I decided to join her this time and fucked her again and stayed the night with her. She was a bit shocked by my actions but allowed me to continue. This became a regular thing for me on getting home, fucking my mother. I was happy to see her slow her drinking and then finally stop drinking. She still let me fuck her and I was quite grateful to her for that. One thing then happened that shocked me at first, she got pregnant. I hadn't thought about my mother getting pregnant. It's not that I thought she couldn't I hadn't thought about it at all. She of course had every test there was and nothing bad was found and so she decided to have the child. I was already sharing her bed every night and that didn't change, having our daughter was a great boost to my mother's self-esteem. Now 4 years later she is her old self raising our daughter and regularly draining my balls. I've a girlfriend now and in my last year of university, whether or not my girlfriend and I marry is fore the future. But regularly fucking my mother is my pleasure and I'll always fuck her as long as she is willing.
