Incestuous Siblings: A Masturbation Marathon

A brother and sister, isolated together, find themselves succumbing to primal urges. She teases him, playing with her wet pussy and big ass, while he tries to hide his growing erection. Caught in the act, they argue, but lust wins out. Naked and aroused, they masturbate in front of each other, her eyes locked on his thick, straight cock. Just as they're about to cross the final boundary, an unexpected intrusion forces them to pause their heated encounter.
