After having sex with my husband, my father-in-law always kept me out. Satsuki Fumi no

It's been five years since I married my husband. My husband was kind and happy, but he was the only one who couldn't help but complained. My husband only has pale sex because he wants children. One day, when such a manneri act continued, I was seen having sex with my husband by my father-in-law who had been living away from home for several months. After that, my father-in-law secretly attacked my husband's place in bed to see his frustration.
