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