SM Noriko's Accidental Peeing(1986)

The chairman of a yakuza gang is murdered, and it is thought to be the work of a rival organization, but it is actually the work of a subordinate gang leader. The gang leader, who was addicted to S&M, was driven to his liking to drink the urine of the chairman's daughter, "Rinko," and drove the inconvenient father to his death. When the executives found out, they were at a loss and consulted their sworn brother, Nozawa. In order to fulfill the wish of the gang leader, who is hovering between life and death from a stroke, they decide to kidnap the chairman's daughter and train her to become a sex slave.
