The bride lives with her husband and father-in-law. I was attracted to my husband's seriousness and got married, but I only worked and had no sex. I was attracted to my father-in-law who was kind to me at such times. From the topic of the news one day, the daughter-in-law learned that her father-in-law and husband had the same blood type. If we have the same blood type, but a wife feels guilty but has immoral thoughts. Moreover, the daughter-in-law insisted on witnessing the scene of her husband hating children and her father-in-law masturbating in her daughter-in-law's underwear, so she seduced her father-in-law and had sex. Then, like a kite breaking a string, the love affair kept repeating itself, and finally... immoral and forbidden incestuous intercourse.
