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