My father-in-law, who lives alone, fell down the stairs and suffered minor sprains in his ankle and wrist. He was unable to perform daily activities, so I decided to stay over and care for him for several days. His condition was lighter than expected, and I felt relieved—until I got caught up in his abnormal sexual desire. An extremely vigorous and completely deranged father-in-law ends up stealing his son's young wife, culminating in a shocking scene where he displays their sex right in front of his own son.
