Saki's husband was transferred to a new job and she had to live with her parents-in-law. Saki was happy to see her parents-in-law getting along well no matter how old they were, but she soon found herself faced with a shocking situation. Even though her father-in-law was a grown man, he had a frightening sexual appetite and would violently embrace her mother-in-law every night. Every night, Saki's crotch ached as she heard their lewd moans and lewd sounds, and she began to masturbate while peeking at her parents-in-law's affair. I wanted to be embraced like an animal, too... and she made up her mind and went to seek out her father-in-law and be embraced by him... "I want my father-in-law's huge cock." The son's wife, in heat, couldn't resist and raped him in the night. Unsatisfied with the bland relationship with her husband... Saki indulges in passionate sex with her father-in-law.
