Margo Sullivan, the seductive stepmother, has been secretly yearning for her stepson's touch. Today, she can't resist any longer. "I've been a bad girl," she confesses, her voice a low, sultry purr. She turns, presenting her round ass, and he groans, his cock straining against his jeans. "Spank me," she begs, and he tentatively brings his hand down, leaving a red mark on her creamy skin. She moans, "Harder," and he obliges, his breath coming in short gasps. She reaches back, pulling her panties aside, revealing her wet pussy. "Now, fuck me like the bad girl I am," she demands.
