Yao, who married into the prestigious Koyama family, had kind in-laws and a comfortable life, but she was anxious about the lack of nighttime activities with her husband. Additionally, she felt uncomfortable seeing her husband and mother-in-law act so intimately... One day, Yao went shopping with her husband and mother-in-law. Left alone, Yao drank alcohol to vent her frustrations and began to masturbate, but midway through, her father-in-law returned home and caught her in the act. Yao, now vulnerable, had her ample breasts fondled by him.
