Hidden in the shadows, I catch my Russian step-mom, a busty milf, lost in self-pleasure. Her big tits bounce as she fingers her wet pussy, moaning softly. I approach, my cock hard, and she notices me, her eyes widening. "What are you doing?" she gasps, but I'm already stripping, my thick cock springing free. She licks her lips, her guilt fleeting as she takes me in her mouth. I fuck her hard, her creamy pussy gripping me as I talk dirty in Russian. She orgasms, her juices dripping down her thighs, and I pull out, cumming in her panties.
