Arthur, a caveman in the throes of raw desire, fantasizes about a primitive fuck session. He grunts and groans, stroking his massive cock while imagining a wild, untamed woman riding him hard. His body glistens with sweat as he pictures her big tits bouncing, her tight pussy gripping his cock, and her nails digging into his back. Arthur's fuck lust is primal and insatiable, a testament to his untamed, animalistic nature.
