My father-in-law, who lives alone, fell down the stairs and sprained his ankle and wrist. It seems that it is inconvenient for him to continue his daily life, so I decided to stay and take care of him for a few days. His condition was surprisingly mild, which was a relief, but I was forced to have sex with my father-in-law, who has an extremely strong sexual desire... My father-in-law, who is a crazy man with extraordinary sexual energy, seduced my slender young wife and showed her sex to his son!
