A mysterious fourth joins the Halloween foursome, her identity hidden behind a mask. Willow, Aria, and Tommy, already lost in pleasure, welcome her eagerly. She licks Aria's pussy while Tommy fucks Willow from behind, their moans echoing in the room. The mystery guest joins in, her tight pussy taking Tommy's cock alongside Aria's. They switch positions, the guest's big ass slapping against Tommy's thighs as she rides him in cowgirl. The night ends with a chaotic mess of bodies, juices, and spent fluids, the mystery guest's identity still unknown, leaving the trio hungry for more.
