After my wife passed away, I lived with my son and his wife for several years. Lately, I couldn't help but worry about my son's wife. Her clothes are too defenseless and her gestures seem to be inviting. And my son and I were working together at night, so my patience was almost at its limit. One day, when I returned home after a gathering, my wife was masturbating intensely. Although she didn't want to look at it, she did and her wife found out.
