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