A fifty-year-old housewife with a modest impression and beautiful white skin, one day finds a toy in her son's room. Stimulated by it, she unconsciously turns to masturbation from her unsatisfied sexual desire. Seeing her mother's mature pussy spread wide and her white thighs, her son loses his reason and lusts intensely. Mother and son greedily enjoy each other's genitals and indulge in forbidden pleasure. The mother, with her white, ripe body flushed, gasps wildly at her son's penis.
