I was home alone, waiting for my wife to come back from her trip. As I was relaxing on the couch, I heard a soft moan coming from upstairs. I was surprised but also excited. It turned out that my stepmom's mistress had come over for a visit. She had a body to die for, with big tits and a perfect ass. She was wearing a tight dress that showed off her curves perfectly. I couldn't resist the urge to watch her as she slowly undressed, revealing her naked body to me. She then proceeded to give me a blowjob that was unlike anything I had ever experienced before. She took my cock deep into her throat, making me moan with pleasure. After the blowjob, she let me fuck her in both her pussy and ass. The sight of her big tits bouncing as I fucked her was enough to make me cum inside her. It was an unforgettable experience that I will never forget.
