Miyuki is also frustrated because her sex life with her husband is not fulfilling. One day, when her husband is not around, her father-in-law's sexual desire explodes and he attacks Miyuki. Miyuki resists, but gradually she becomes addicted to her father-in-law's rough cock, and from then on, she is tied up, deep-throated, vibrated, and creampied every day. One day, the husband comes home early and witnesses his wife and father having sex.
