At a traditional Japanese inn, the young, sultry innkeeper welcomes a group of eager males for a New Year's celebration. As the night unfolds, they propose a game of King's Game, a thrilling test of her obedience and endurance. The rules are simple: she must follow any command given by the 'king.' The game begins innocently, but soon escalates as she's ordered to strip, revealing her toned, tattooed body. The men's desires grow bolder, demanding she pleasure herself, and then them. The night intensifies as she's filled with multiple loads, leaving her marked with their New Year's greetings.
