Dangerous temptation of an incestuous and erotic mother

My father was busy with work and would spend the night at the office, and my mother and I lived like a single-mother family. It happened one day. My mother's faint moans and sticky sounds were leaking from the bath. When I timidly peeked inside, my eyes caught my mother's obscene behavior with her fingers in her genitals. At that moment, the wall of common sense called reason collapsed inside me... And before I knew it, I was licking my mother's wet genitals.
