My parents don't know that I'm dating my stepsister. Of course, once we started dating, we began having sex and our perverted natures gradually became exposed... Eventually, we even sneaked intimate moments when our parents weren't looking! We couldn't hold back any longer and had sex right in front of them with her long skirt concealing it! My upper body remained calm while my lower body was soaked, merging together! With my parents nearby, the thrill of possibly getting caught made us climax over and over! We are no longer satisfied with ordinary sex; we have become ultra-perverted and insatiable step-siblings!
