In the throes of New Year's Eve, Cock Ninja Studios' Kat gives in to her taboo desires, inviting her stepbrother to stretch her tight asshole with his massive cock. She sucks him first, feeling his length hit the back of her throat, then mounts him, riding him until he spanks her ass, pushing her deeper onto his dick. He pounds her, making her scream, before pulling out and coating her ass with his hot, thick cum.
