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