No no you're doing it all wrong. You gotta hide the camera in a black t-shirt with the lens poking out through one of the arm holes and be sure to use some black tape to cover up the red LED light. Mom will never notice! hah
Her asshole is ambushed by a giant cock but she manages to evade the intruder. Her anal virginity is safe for now... until the camerman can come up with another $100.
