A curious brother stumbles upon his girlfriend's hidden anal fetish as she innocently bends over to pick up a fallen book. His eyes widen at the sight of her tiny, puckered hole, barely hidden by her lacy thong. Unable to resist, he approaches her from behind, running his hands over her curves. She gasps, pushing back against him, silently giving her consent. He slides a finger along her crack, feeling her tightness, before slowly pushing it inside. She moans, her body relaxing, eager for more. He adds another finger, scissoring them, preparing her for his thick cock.
