In the throes of a road trip, Mama's curiosity gets the better of her as she discovers her son's hidden desires. She finds him in the backseat, his hand wrapped around his hardening cock, his eyes closed in ecstasy. Instead of chastising him, she's intrigued, her own body reacting to the sight. She decides to give in to her taboo urges, taking his length into her mouth, feeling him grow harder against her tongue. He looks down at her, surprise and pleasure warring in his eyes, before she mounts him, riding him slowly, their eyes locked.
