One day when a small, neat and clean fifty mother who looks good with a smile was working on housework as usual, she finds a used onahoru in her son's room. Inspired by the scent of her drifting semen, the fifty-year-old mother goes crazy with her masturbation, exposing her strong and intense libido that she had suppressed. Her son, who witnessed her mother's appearance, violently devours a ripe fifty-year-old man with distorted love and carnal desire. A fifty-year-old mother who shakes herself in fellowship with her son drowns in her greedy pleasure.
