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