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