As the train rumbles on, the stranger leans in, whispering filthy fantasies into the willing ear. The commuter's breath hitches as a warm, wet tongue traces their lobe, sending shivers down their spine. The stranger's skilled mouth descends, engulfing the commuter's throbbing cock, expertly working it beneath their coat, hidden from prying eyes. The commuter's grip tightens on the pole, knuckles white, as they struggle to maintain composure, the stranger's relentless sucking threatening to expose their secret pleasure.
