This happened in the summer of 2010, after I graduated from high school. I had always been VERY interested in sex and while being an awkward asf teenager who never even dated until after this particular summer, I was always jacking off to the thoughts of many women I knew both my age and older, usually older finding them much more attractive than half the women I knew personally (usually for just being outright cunts to me in school and even since then).
My mom, bless her soul, was one of the most beloved people in my life, seeing as how being the youngest out of five siblings (all four others being half-siblings) and my parents separated -never married, really- left me living with my mother for most of my life at that time. At first she was perfectly healthy, working a part-time job helping my grandmother and the older (and hotter) of my twin half-sisters put DMV paperwork through the system. Then, my cat bit her foot after she accidentally stepped on his tail.
