As the bus pulls into the stop, a secretive glance is exchanged between two passengers. They slip off to the side, away from prying eyes, and begin their dance of desire. The taller of the two presses the other against the cold, metallic wall, his hands wandering, exploring, until he reaches the object of his lust. He sinks to his knees, pulling the other's pants down, and begins to rim him, his tongue flicking and teasing, the sound of wet, hungry kisses filling the empty bus stop.
