Chaoyang, who was working hard to raise his only son in a single-mother family, fell in love with a man he met at a part-time job and remarried. It was a condition of remarriage to live with my father-in-law, but I was willing to live with him because my father-in-law took over the large amount of debt I had made to live. I was living happy days with four newly created families. One day, Chaoyang witnesses his father-in-law sucking his son's cock. A frightened and trembling bride also attacks her to fall asleep, and her father-in-law who makes the morning sun. Since this day, Chaoyang, who has been taken down by his father-in-law, gradually drowns in the cock of his perverted father-in-law.
