As the metro doors slide shut, a stranger in a trench coat presses against the woman, his erection evident through his pants. She gasps, her body tensing, then relaxes, her eyes meeting his in a silent understanding. The train lurches forward, jostling them together. He leans in, his lips brushing her ear, "What would you do if I fucked you right here?" She swallows hard, her pussy throbbing at the thought. His hands roam her body, cupping her breasts, sliding down to her hips, pulling her against him. She can feel his hardness, the promise of what's to come. The train stops, passengers get on and off, oblivious to the couple lost in their forbidden dance, their bodies yearning for the taboo pleasure they're about to share.
