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