With her arms bound above her head and legs spread wide, a horny submissive awaits her anal initiation. Her dominant partner lubes up her tight asshole, slowly pushing a finger in, making the sub gasp. The dominant replaces their finger with a thick dildo, fucking the sub's ass gently at first, then picking up speed. The sub's moans fill the room as she's used roughly, her body jerking with each thrust. The dominant brings the sub to the edge of orgasm, then pulls out, leaving her wanting more as they tease her with a soft touch before resuming the hard fucking.
