A sudden power outage plunges the metro car into darkness, the only light flickering from the stranger's phone as he brings up a racy video. The woman's breath hitches, her nipples hardening against her silk blouse. He leans in, his breath hot on her neck, and whispers, 'I bet you taste as sweet as you look.' She turns to him, her eyes reflecting the dim light, and responds, 'Find out for yourself.' Their lips meet in a hungry, passionate kiss, their bodies pressing tightly against each other, hands exploring, as the train continues its silent, secret journey through the night.
