Empty carriage, only the rhythmic clatter and serenity naked. She locks the door, strips, and straddles the seat facing the window. Moonlight paints silver across her skin as she chants “serenity naked” in time with the rails. Four fingers stretch her open; the wet slap echoes louder than the train. “Everyone outside, see serenity naked come,” she gasps. The train enters a tunnel—darkness swallows everything except her rising “serenity naked, serenity naked, fuck, serenity naked!” until she explodes, soaking the leather in a flood of unstoppable “serenity naked” release.
