Due to her husband's lack of interest, Yukiko had been living a sexless marriage for years after giving birth to her son. To cope with her loneliness, she spent her nights pleasuring herself. One day, her son Akira caught her in the act. Unlike her husband, Akira was kind, considerate, and bursting with youthful desire. Amazed by his incredible stamina, Yukiko forgot the boundaries between mother and son, and the two began craving each other intensely. Their starved bodies pressed together, lips locking as an endless, forbidden union began between them.
