Cheating Is Better When The Wife Is Around

My wife is smoking hot, but her stepsister is a pervert, so you can't blame me. How could I resist pounding her ass when she was wearing that tiny bikini right in front of me? I know that she saw how hard my dick was, but she's the one who came looking for it behind my wife's back. If she was as horny as me, all I could do was shove my dick in her mouth. I'm glad I did because her throat was deep, her pussy was tight, and knowing that my wife could catch us at any moment made everything even better.
