If Only They Knew

My wife's brother is engaged to a girl I used to fuck in high school and my early 20s. Not only that, I had a threesome with her and her older sister in the back of their family Suburban junior year. After he introduced us and we obviously knew each other my wife asked "how well" did I know her. I lied and said we used to hang out in the same friend group. I suppose they'll never know I came in every hole on that women's body for the better part of 5 years. I was her first anal, her first cum swallow, and the reason she got on birth control in high school. She was my also my first anal, first girl to swallow my cum, and only threesome.
