After years of a sexless marriage, Yoko's deep-seated frustration had warped her mind and stripped away her reason. One day, noticing her son's cock had grown fully into an adult's size, she fell into a forbidden relationship. Since then, driven by uncontrollable desire, Yoko began acting shamelessly, constantly begging for her son's cock. Her son's hesitation and her husband's return home only deepened the chaos, but she didn't care. Obsessed with sex, Yoko became utterly fixated on her son's perpetually erect cock. Once again today, she lunges at him with an aroused expression, forcing him to creampie her repeatedly until he reaches his limit.
