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