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