Unseen passion: a nighttime tryst in a crowded public train

In the crowded compartment of a public train, under the dim light, a 28-year-old woman with long, black, straight hair sat casually. Her red lips were wrapped around a man, her tongue flicking out suggestively. The climax unfolded subtly, a cumshot in her mouth, leaving a trail on her tongue. Eyes outside the window showed a dark, rain-soaked night, but inside, it was an amateur porn scene playing out unnoticed by the casual passengers.
