Affair

My mother-in-law arrives tonight and will spend a week with us as we celebrate our youngest graduation from high school. I will pick her up at the airport and we will be in each other's arms and kissing like teenagers as soon as we get to the car. Our affair is in its third year and it just keeps getting hotter and juicier. My wife has no clue and my father-in-law is so obese he can't travel.
