Mikuru had been receiving fertility treatment for three years, but her father-in-law provided financial assistance for expensive medical treatment that was not covered by insurance. However, the assistance was cut off at the kinship meeting, and the husband begged his father-in-law to continue. My father-in-law wanted to taste Mikuru's body, so he suggested that he should do it only once as a replacement condition. The husband had no choice but to give OK only once and persuade his wife to embrace him. I am embraced by my father-in-law in front of my husband, but when my husband leaves the room, I get drunk with pleasure from the sense of immorality and get acme many times. I couldn't forget the pleasure, and I was excited to be played with by going to my father-in-law's house at a later date, and I culminated many times.
