I have a girlfriend that I love. And both she and I are very ordinary people. I'm not interested in perverted things, and I just wanted to have normal sex... but when her sister appeared, my sexual desires became distorted and I started to go crazy! The cleaning-loving sister's unconscious and defenseless sheer ass, her huge ass that was out of the ordinary, and even her thong that was digging into her huge ass, and finally the excitement of doing it next to her even though she was nearby. Everything is fresh and addictive! I want to bury my face in her sheer ass more, be pressed down, die and cum quickly!! I want to move her thong and insert it and be crushed by her full weight! Ah... I'm cheating on her again today to satisfy my distorted sexual desires...
