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