Kate, the dominant stepmom, lounges on the couch, her pussy bare and inviting. Her stepson, having finished his chores, enters, his eyes drawn to her glistening slit. "Homework's done, Mom," he says, his voice thick with lust. She smirks, "Then you know what to do." He drops to his knees, his tongue tentatively exploring her folds. He learns fast, finding her clit, sucking it, making her gasp. She guides him, her hips moving in rhythm with his tongue, until she cums, her pussy flooding his mouth.
