Daughter-in-law at the mercy of her father-in-law ~ Surrender yourself to the pleasure of falling ~

Mr. and Mrs. Tsuruta moved to her husband's parents' house to buy their own home. Her father-in-law, Bungo, who was divorced at a young age, lives alone at her parents' home, and she happily accepts them. One day, when her husband is alone on a business trip, Mai's lustful father-in-law, who had been watching for an opportunity, pushes Mai down. The father-in-law's desire knows no bounds, and he doesn't care about Mai, who is forced into a relationship and sinks into deep sadness. After this day, her happy life changed completely, and the days of humiliation as she was toyed with by her father-in-law began.
