My mother is secretly in heat as she gazes passionately at my cock, her only son, who has become erect after seeing my mother's defenseless breasts and panties. We are in a relationship where we should never touch each other, but when I press my erect cock against her so that my father doesn't find out, my mother's body becomes ablaze. Although she initially resists, she finally allows her son's cock to penetrate deep inside her hot pussy.
