A pretty wife has been married to her husband for many years, but their relationship has become dull. She feels unhappy and doesn't know what to do.

Thankfully, they live with her husband's father. Things changed when one night, she peeked into the dad's room and saw him masturbating. This turned her on and reminded her of the old days when she used to date older men.
