Rita Mills, the petite blond, sneaks up on her stepson as he's pleasuring himself. Instead of being shocked, she's turned on, pushing her huge labia and throbbing pussy against his dick through her panties. He rubs her, feeling her wetness seep through. She encourages him, "Don't stop, baby. Cum in my panties. Fill me up." He obliges, his hot cum soaking her panties and dripping out, leaving her a creamy, satisfied mess.
