I remarried and decided to live with my wife and stepchild. My stepdaughter has a cute face and a firm butt, and I couldn't stop getting turned on, so I did something unbecoming of a parent. I never thought the day would come when she would find out. One day, my stepdaughter whispered in my ear, "You've been secretly sniffing my underwear, haven't you?" and made me feel uneasy. After that, she started playing with my nipples, straddling my rock hard cock and shaking her ass, so I couldn't help it... Even though my wife was right next to me, I had sex with my abnormally horny stepdaughter over and over again!
