Alone in her car, a woman named Maria finds solace in self-pleasure as she cruises through the city. Her fingers trace the curves of her body, teasing her nipples through the thin fabric of her blouse. She feels a growing warmth between her legs, her panties growing damp as she slips a hand under her skirt. Her touch becomes more insistent, her breathing ragged as she works herself into a frenzy, oblivious to the world outside her window.
