A mother who is fifty years old and has a strong libido spends her days in agony, violently aching her ripe and growing body. A son who witnesses the appearance of a mother who uses toys to calm her strong desire and indulges in masturbation. A mother who feels abnormally excited by being seen by her son invites her son to spread her own pussy. The mother who straddles the face and licks the ripe mako and raises the voice of indecent pleasure awakened to the forbidden fellowship and escalated the act. A fifty-year-old mother who plays with Ji-ko, tastes semen, and guides her to Oma-ko!
