My stepsister cheats on her boyfriend with another man while I record it for blackmail

I've always been intrigued by the idea of my stepsister cheating on her boyfriend, and I've been keeping a close eye on her ever since. When I discovered she was seeing another man, I knew I had to act. I convinced her to bring him over under the pretense of filming a homemade porn video with her girlfriend. Little did he know, I had a plan. As soon as they started getting intimate, I sprang into action, recording every moment. The sight of her tight ass bouncing on his big Latino cock was too much to resist. I knew I had to join in, turning our foursome into a wild, unforgettable encounter. The sight of her cheating on her boyfriend, all while I recorded it for blackmail, was the ultimate thrill. I can't wait to see what else she's capable of.
