Brother, home alone with his sexy step sis, can't keep his eyes off her as she prances around in revealing outfits. One day, she catches him spying and decides to give him a show he won't forget. Teasingly, she strips, revealing her luscious body, and spreads her legs, fingering her dripping cunt. Brother's cock tents his shorts, and she pounces, pushing him onto the bed and straddling him. She grinds on him, then impales herself on his cock, bouncing up and down, her tits jiggling as they fuck raw, their taboo lust consuming them.
