I've always been powerless around my stepsister, especially when she's wearing those tight shorts that show off her amazing ass. She knows exactly how to get me going, and it's not just her ass that's driving me wild. Her body is pure perfection, with a perfect booty and big tits that are just irresistible. I've caught her playing with herself before, and it's the hottest thing I've ever seen. I've always wanted to join in, but my wife doesn't seem to be into it. I'm a bit of a cuckold, and I'm okay with that. I know my wife is watching me fuck my stepsister, and it turns me on even more. The thought of my wife and stepsister having a threesome is just too much to handle. But for now, I'm happy to continue my secret rendezvous with my stepsister, hoping that one day, my wife will join in.
