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