My Sister Slept With My Husband While I Babysat Her Kids,

I was the fool who babysat my sister Linda’s kids while she slept with my husband, Jack. I thought kindness would be rewarded, but after our wedding, Jack grew distant, glued to his phone, ignoring me. One night, Linda asked me to watch her kids again, claiming she needed to rebuild her life. I went, despite Jack’s indifference.

At Linda’s, I sat alone, waiting hours without a text. An asthma attack forced me to drive home for my inhaler, only to find Linda’s car there. Upstairs, I caught them in our bathroom, laughing, surrounded by wine and rose petals. Betrayed, I grabbed my inhaler and left, vowing revenge.

I took a hair from Linda’s son, Tommy, suspecting the truth. Two weeks later, DNA results confirmed a 70% match—not enough to be sure, but enough to stir doubt. I confronted Jack and Linda with the results, exposing her affair with Jack’s brother, Rick, who paid her to keep quiet. Their lies unraveled as they fought. I took the kids for ice cream, leaving Linda and Jack to their crumbling lies. My sister’s betrayal was her downfall; my revenge was sweet, holding the kids’ hands under the warm sun.
