The black beauty's eyes gleam with lust as she kneels, her round, firm ass pushing back against the cold wall. She licks her lips, savoring the taste of pre-cum as she engulfs the throbbing cock, her head moving in a hypnotic rhythm. She can feel the stranger's pleasure, his cock pulsing in her mouth as she sucks, her tongue flicking against the underside. She takes it deep, gagging slightly, but her hunger is insatiable. She can feel her own arousal, her pussy throbbing, wishing the cock in her mouth was inside her, stretching her, filling her completely.
