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