My family wasn’t exactly a normal one. My younger sister and I were raised by a single mom, who by anyone’s standards was a MILF. I’d often hear strangers fucking my mom in the middle of the night. It didn’t really bother me, as she had ways of keeping me happy too. The whole family dynamic rested on sex; favors were repaid with blowjobs, arguments were settled with hate fucking, punishment was sexually dealt. We were taught how to masturbate as soon as we hit puberty; by the time I was a teenager it was like second nature to me.
My sister was a bit younger than I am and had hit puberty a few years ago. She adopted all of my mom’s traits; blue eyes, dirty blonde hair, massive breasts, everything. After a recent discovery, she’s been masturbating more and more. According to my mom, she learned how to squirt. I guess it explains why she’s been so loud. Her ragged moans could be heard all the way from the basement.
