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