The busty brunette's eyes widen as she realizes her man's intention. "Not there," she protests weakly, but her body betrays her, already craving the forbidden sensation. He lubes up her tiny, untouched asshole, rubbing it gently before pressing his cockhead against it. She winces as he pushes past her tight ring, feeling every inch of his thick shaft as it invades her virgin ass. He fucks her slowly, letting her get used to the intense feeling, before increasing his pace, pounding her asshole and making her scream with pleasure and a hint of pain.
