After her husband's death, Natsuko Kayama's drinking increased, and her libido grew uncontrollable. She began engaging in an incestuous relationship with her son, giving him a blowjob before he leaves for cram school, then masturbating as she lingers in the afterglow. In the evening, her younger brother visits, and fueled by alcohol, they have sex. When her son returns home, she gives him another blowjob in the bath, then continues with more sex in the bedroom. Never satisfied, Natsuko relentlessly pursues deeper pleasure. This is the long-awaited, intensely erotic masterpiece featuring Milf Natsuko Kayama, blessed with huge breasts and a voluptuous ass.
