Mei's son had only ever seen her as a woman, not as his mother. One day, after she became pregnant with their second child, jealousy overwhelmed him and he assaulted her. From that day on, she was tormented by an uncontrollable, intense sexual desire. Eventually, unable to endure it any longer, Mei decided to accept her son purely as a man, choosing to satisfy her urges before her body grew larger from pregnancy.
