In the grimy, abandoned tunnels of the metro, two strangers meet, their bodies drawn together by primal lust. They grope and grind, their clothes falling away in the dim light, revealing bare skin sticky with sweat and want. The man's thick, uncut cock springs free, throbbing and ready. The woman, her pussy dripping wet, drops to her knees, taking it deep into her throat, gagging slightly as it hits the back of her mouth. They fuck hard and fast, their bodies slapping together, the echo of their moans filling the empty station. The man grabs her hips, pulling her onto him, impaling her on his cock, as she rides him, her tits bouncing, until they both come undone, their juices mixing on the filthy ground.
