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