My father-in-law fell down the stairs, spraining both his ankle and wrist, leaving him unable to perform daily activities normally. As a result, I had to stay over for several days to take care of him. His condition was lighter than expected, which relieved me, but my father-in-law's sexual desire was abnormally strong, and I eventually succumbed to his advances. Full of vigor, he ended up taking my virginity and even flaunted the sex in front of my son, leading to a shocking and intense NTR experience.
