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