After the father's death, the family is torn apart by a fierce battle over inheritance between brothers. To them, their mother is nothing more than a housekeeper, her presence as insignificant as air. Yet the sons harbor abnormal desires toward her, forcing her to obey their relentless demands. One day, a son commands her: "If you want to stay in this house, masturbate for me!" Trembling at his words, the mother has no choice but to satisfy his lust with her own body. Drenched in sweat, she accepts her son's penis, welcoming the pleasure deep within her aching womb until she finally reaches climax. An ordinary housewife is dragged from her daily life into a grotesque, twisted world—this story transcends mere eroticism, exposing the depths of perverse family dynamics and raw desire. The dark truth of this distorted household emerges in vivid detail.
