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