I couldn't believe my luck when my hot stepdaughter started teasing me. Her mom, my wife, was clueless, always out shopping or at her yoga classes. One afternoon, I caught my stepdaughter touching herself in the living room. She saw me and just smirked, lifting her skirt higher. I couldn't resist. We ended up fucking on the couch, trying to keep quiet, but the thrill of getting caught only made it hotter. Her moans were driving me wild, and I knew we were playing with fire, but I couldn't stop.
