after my wife passed away, i lived with my son and his wife for years. recently, i couldn't stop thinking about my daughter-in-law. her clothing was too revealing, and her gestures were inviting. she was also having sex with my son at night, and i was at my limit. one day, there was no gathering, so i returned home to find my daughter-in-law masturbating intensely. i thought i shouldn't watch, but i couldn't help it, and she caught me. later, my daughter-in-law approached me. it seemed she liked being watched by me and wanted me to watch again.
