A slim, 30-year-old Japanese wife, Masako, finds herself in a dangerous game of chance with her lover. After a few glasses of wine, her resolve weakens, and she surrenders to her carnal urges. In a haze of alcohol and lust, she lets him fill her tight pussy with his throbbing cock, her body convulsing in intense, squirting orgasms before he pulls out, painting her with his hot, sticky seed.
