What I wanted to do when I became my father-in-law ~ My cute wife has arrived at my house, which I love AV~

A way to realise a completely fictional and fantasy AV world in a realistic way that is almost as legal as possible. The first step is to become a "father-in-law." I want to make my dream come true, where I smell my wife's underwear while my son is away, peek into the bath, wash my erect cock, grab my weakness and turn it into a sex slave. This is a record of a simulation of a real father-in-law life in which a middle-aged man who was always watching his father-in-law's AV, finally becomes a real "sex-in-law" after his son's marriage and living together, and practices domestic eroticism.
