My girlfriend's best friend is a 'cojona' - a horny, insatiable vixen who loves to get fucked. Today, she's all mine. I push her against the wall, her ass on full display, and bury my face between her cheeks. She moans and writhes as I lick and tease her asshole, making her 'grabada' - marked by my desire. I slip a finger into her tight pussy, feeling her stretching around me. She begs for more, so I give it to her, filling her ass with my hard cock. She screams and claws at the wall as I fuck her hard and deep, her ass taking every inch of me. I can feel her tightening around me, her body ready to explode. I pull out and cum all over her ass, marking her as mine.
