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