Living under the tyranny of an alcoholic father, the mother endures in silence. As her son, he couldn't understand why she submitted so obediently. One night, noticing a faint light seeping from his parents' room, curiosity drove him to quietly approach. There, he witnessed his mother performing oral sex on command from his father. But just before penetration, her arousal faded, and the father left abruptly to go drinking. Seizing the moment, the mother began touching herself, soothing her still warm and heated body with self-pleasure. The next day, while the rest of the family was out, the son found his mother napping. Intending only to cover her with a light blanket, he suddenly recalled seeing her masturbate the previous night—arousal surged within him, and he began touching her body. The mother awoke and tried to resist, but her strength failed. Overpowered, she was forcefully penetrated. In that moment, the son's desire and the mother's pure body became one.
