@reddit_jj4: "I've been sleeping with his brother since our second date," my wife boasted with her friends. "He still thinks those business trips were real." My former classmate sent me the video immediately, without revealing what I knew. I contacted a geneticist about our newborn son's unusual features. On Christmas morning, I presented her with paternity results showing my brother was the father. This morning, she was at my doorstep, begging for forgiveness. #reddit#foryou#usa
