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