On the streets at night, explicit acts drive a woman into abnormal pleasure. She strips her underwear in a drinking district, lifts her skirt to expose her crotch while waiting at a convenience store register, and runs around naked in front of vending machines—acts that destroy the boundaries of daily life and turn her into a pervert. Hidden by the darkness of night, these actions gradually transform her body. Her pussy becomes soaked and wet, and the pleasure continues until the night ends. The city streets at night become the stage symbolizing her metamorphosis.
