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