A Third in the Marital Bed His ‘Sister’ as a Wedding Gift

On our wedding night, my new husband’s childhood friend walked into our bedroom carrying a pillow. “Rider, you promised I could sleep in the middle,” she declared, pouting as if it were her right. He just laughed it off, telling me not to be so uptight. So I picked up the two-billion-dollar investment portfolio I brought to this marriage and walked out. They thought it was a tantrum. They didn't realize I was about to become their ruin.
