Shouko lives a happy married life with her husband. Although she lives in harmony with her father-in-law and mother-in-law, she feels disgusted by her father-in-law, who is sloppy and constantly sexually harasses her. One day, unable to control her sexual desires, her father-in-law rapes her with his raw cock and even cums inside her. As his big breasts are played with, Shouko is completely seduced by his technique, which is better than her husband's. Her father-in-law's semen continues to be poured into her uterus with his thrusts, which will definitely get her pregnant! Even though she should hate it, her body is starting to feel pleasure. He cums inside her over and over again, to the point of becoming pregnant.
