At 16, mother "Ran" became pregnant and gave birth to her son. Having received a child from youthful indiscretion, she raised her son alone, supporting their household through night work. Her son attended a part-time school, growing steadily into adulthood. Yet Ran remained unaware that her son had begun to see her as a woman. As the young man matured, he started feeling desire for his beautiful, youthful mother. His urge to possess her exclusively surfaced as lewd, uncontrollable lust, driving him to make advances toward Ran. Despite resisting at first, overwhelmed by her son's forceful advances as a grown man, her body eventually responded—her pussy wetting with arousal. A story of a mother and son torn between forbidden emotions and carnal desire.
