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