Living with my stepmother. My stepfather is away for work, so it's just me, my wife, and my stepmother living together. My mother is his second wife—she's not much older than me, incredibly beautiful, and has a stunning figure. One day, I caught my stepmother in the act of cheating. Using that secret against her, I pressured her into giving in to my advances. At first she refused, but after persistent touching and foreplay, she gradually gave in, and we ended up having sex.
