That JAV

One day, Mari, a teacher, and her husband, Philosophy, a fellow teacher, visited the home of Yugo, a student in her class who was refusing to go to school. The school had given up on Yugo because of his problematic behavior, but over her objections, they came to visit him at home. However, as soon as Yugo welcomes Mari, he makes her and Philosophy drink tea containing sleeping pills, and then lays Mari on the floor in front of Philosophy. During the act, Mari's father Satoshi, a yakuza, and his gang of thugs appear, and the three of them circle around Mari.
