A couple decided to live with their father-in-law who was living alone. Not knowing that her father-in-law likes big breasts, Leona, a housewife, spends all day on the defensive. Leona unconsciously stimulated her father-in-law's lower body with her puffy breasts, and when she saw that her father-in-law could bear it, she planned to lure her into buying branded goods. The father-in-law could not stand Leona's provocation and did wrong. The father-in-law was once tagged and forgot that he was his son's daughter-in-law and constantly devoured his desires.
