My Sister Slept With My Husband While I Babysat Her Kids, So Her Biggest Secret Became My Sweetest Revenge — Story of the Day

I was the naive one, babysitting my sister Linda’s kids while she betrayed me with my husband, Jack. I thought kindness would be rewarded, but my marriage crumbled as Jack grew distant, ignoring me for his phone. One night, Linda asked me to watch her kids again. Exhausted, I agreed, but an asthma attack forced me home for my inhaler. There, I found Linda’s car and heard laughter upstairs. In our bathroom, Jack and Linda were together, carefree in my own home. Devastated, I grabbed my inhaler and left, vowing revenge.
Realizing Linda’s son Tommy didn’t resemble her ex, I collected his hair for a DNA test. The results confirmed a 70% match—not enough to be certain, but enough to stir doubt. When Jack moved in with Linda, I confronted them with the results, implying Tommy was Jack’s brother Rick’s child. Linda admitted to an affair with Rick, who paid her to keep quiet. Jack, furious, realized he was just her “bonus.” As their lies unraveled, I took the kids for ice cream, leaving Linda and Jack to their crumbling deceit. Revenge tasted sweeter than chocolate and strawberry combined.
