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