As the metro train screeches to a halt, the woman turns, locking eyes with the man behind her. She whispers, "I like it black and deep in my ass." He gulps, his cock throbbing, and she smirks, guiding his hand to her soaking wet pussy. He feels her juices coating his fingers as he plays with her clit, making her squirm. She reaches back, unzipping his pants, and pulls out his stiff, eager cock. She lubes it up with her own juices, positioning it at her asshole. As the train starts moving again, she slowly sinks down, taking him deep inside her, her ass stretching to accommodate his thick length. She rides him, her ass slapping against his thighs, as the train rocks them, their moans drowned out by the rhythmic clatter of the tracks.
