Once Vincent begins fucking his gorgeous mother, Anna, he doesn’t stop. Every weekday afternoon after he returns from college, Vincent and Anna kiss passionately and fuck at least three times every afternoon while his father is at work. Anna becomes so horny that she lets her son and secret lover, Vincent, fuck her every time that they are alone, in every room in their house, and in every position. During one of their “fuck sessions,” two of Vincent’s millions of sperm meet two of Anna’s eggs inside of her fallopian tube and penetrate them, releasing Vincent’s DNA, which combines with Anna’s eggs to form two zygote cells inside Anna’s womb, impregnating her. Nine months later, Anna gives birth to twins, a baby son who looks just like Vincent and a baby daughter who looks just like Anna. Over the next nine years, Vincent fucks and impregnates Anna eight more times, and Anna gives birth to four more baby daughters and four more baby sons.
