In the dimly-lit, echoing metro, Harley Quinn, clad in her signature red and blue, finds solace from the Joker's chaos. She strokes herself, moaning softly, her fingers dancing over her clit and inside her wet pussy. The metro's rumble vibrates through her, adding to her pleasure. Suddenly, the Joker appears, pushing her against a pole. He unzips, revealing his massive, veiny cock. Harley, eager, hops on, riding him reverse cowgirl, her tits bouncing. The metro's sway rocks them, their fucking syncing with its rhythm. Harley's cries echo as the Joker's hot cum splashes inside her, dripping down her thighs.
