My husband's father, who lives alone, fell down the stairs and sprained both his ankle and wrist. Since he was having trouble with daily activities, I decided to stay over and care for him for several days. But his condition turned out to be much better than expected, and I started to relax—until I realized his sex drive had become uncontrollable. Overflowing with stamina, my completely depraved father-in-law began aggressively pursuing me, pushing me into a corner. What shocked me even more was his confession: he had already slept with my husband's wife. Then came the twisted turn of events—he forced me to watch as he had sex with her, flaunting their incestuous affair right in front of her own son.
