In the heart of Campinas, Mary Butterfly, the exhibitionist wife, takes her carnal cravings to the streets. With husband Alexandre Drazdauskas filming, Mary teases and tantalizes, her naked body a sight for passersby. She chats with a flanelinha, a street parking attendant, who can't help but stare at her bold display. Mary's moans fill the car as she pleasures herself, her excitement growing with each attention-filled moment.
