Beneath the harsh fluorescent lights of the metro, a man and woman, bound by no names or histories, lose themselves in a dance of lust. She sits, legs parted, inviting his touch. He responds, fingers tracing her wet slit, making her gasp. The train's motion rocks them, mimicking their lovemaking. She takes him in her mouth, tasting the salt of his skin, before he lifts her, impaling her on his cock. The city's noise fades as they fuck, their bodies slapping together, until they climax, bodies tensing, release washing over them like the train's rush of air.
