Empty carriage, only the rhythmic clatter and 五 十 音 順 カタカナ. She locks the door, strips, and straddles the seat facing the window. Moonlight paints silver across her skin as she chants “五 十 音 順 カタカナ” in time with the rails. Four fingers stretch her open; the wet slap echoes louder than the train. “Everyone outside, see 五 十 音 順 カタカナ come,” she gasps. The train enters a tunnel—darkness swallows everything except her rising “五 十 音 順 カタカナ, 五 十 音 順 カタカナ, fuck, 五 十 音 順 カタカナ!” until she explodes, soaking the leather in a flood of unstoppable “五 十 音 順 カタカナ” release.
