Haruka married into the famous Kayama family. My husband’s family was kind and there was nothing for me, but I felt uneasy about the lack of nightlife with my husband. In addition, I feel uncomfortable with my husband and mother-in-law, Natsuko’s familiar appearance that I can’t imagine being a parent and child. One day, my husband and Natsuko went shopping together. Haruka, who is left alone, feels a pain in his body while drinking alcohol to relieve his worries and indulges in masturbation. In the meantime, her father-in-law comes home, and Haruka, who has been seized her weakness, is played with her plump breasts.
